Description

構成多重跳接式網路的通訊終端、以及多重跳接網路 Communication terminal forming a multiple jumper network, and a multiple jumper network

本發明係有關於構成多重跳接式網路的通訊終端、以及多重跳接網路。The present invention relates to a communication terminal forming a multi-hop network and a multi-hop network.

多重跳接式網路具備複數的通訊終端。包含於複數的通訊終端的各通訊終端會使用電力系統供給的電力來與其他的通訊終端進行無線通訊。因此，各通訊終端在電子系統發生停電時，就變得不能與其他的通訊終端進行無線通訊。另一方面，各通訊終端在該各通訊終端故障而無法動作的情況下，也變得無法與其他的通訊終端進行無線通訊。因此，難以區分各通訊終端變得無法與其他的通訊終端進行無線通訊的原因是電子系統發生停電、還是各通訊終端故障而無法動作的那一者。Multiple jumper networks have multiple communication terminals. Each communication terminal included in the plurality of communication terminals uses the power supplied by the power system to wirelessly communicate with other communication terminals. Therefore, each communication terminal becomes unable to perform wireless communication with other communication terminals when a power failure occurs in the electronic system. On the other hand, each communication terminal becomes unable to perform wireless communication with other communication terminals even when each communication terminal fails and cannot operate. Therefore, it is difficult to distinguish whether the reason why each communication terminal becomes unable to perform wireless communication with other communication terminals is a power outage in the electronic system or the failure of each communication terminal to operate.

因此，有一種提案是包含於複數的通訊終端的通訊終端上，會設置供給來自電力系統的電力的通常電源部，更設置供給會被電池、蓄電池的電力儲藏器放電的電力的預備電源部，讓該通訊終端使用預備電源部所供給的電力來發出停電通知。Therefore, there is a proposal to include a communication terminal including a plurality of communication terminals with a normal power supply unit that supplies power from the power system, and a backup power supply unit that supplies power that is discharged by the power storage of batteries and storage batteries. Let the communication terminal use the power supplied by the reserve power supply unit to issue a power failure notification.

專利文獻1所記載的技術中，廣域監視系統是由母局、切換子局以及複數的子局所構成（段落第[0018]-[0019]段）。子局是由主電源部、預備電源部、電源切換部、控制器部、資訊儲存部、無線通訊部及監視控制部所構成（段落第[0027]段）。主電源部供給來自系統電源的電力（段落第[0028]段）。預備電源部在能夠以電池、雙電層電容器等構成，主電源的輸出下降或無輸出的情況下，會做為預備使用（段落第[0029]段）。電源切換部為了在有主電源的輸出電壓的情況下供給電力至端末，控制電力供給的流動（段落第[0030]段）。主電源的輸出不滿閾值時，切換成來自預備電源部的輸出（段落第[0030]段）。控制器部會執行電源切換部的電源切換監視等（段落第[0031]段）。無線通訊部會以電波發出控制器部所產生的訊號，並將接收的訊號交給控制器部（段落第[0033]段）。在廣域監視系統中，預備電源動作子局的通訊次數被壓抑，結果能夠抑制預備電源的消費，進行預備電源動作的子局能夠維持長時間的通訊（段落第[0145]段）。In the technology described in Patent Document 1, the wide-area surveillance system is composed of a parent station, a switching slave station, and a plurality of slave stations (paragraphs [0018]-[0019]). The slave station is composed of a main power supply unit, a backup power supply unit, a power switch unit, a controller unit, an information storage unit, a wireless communication unit, and a monitoring control unit (paragraph [0027]). The main power supply unit supplies power from the system power supply (paragraph [0028]). The backup power supply unit can be used as a backup if the output of the main power supply drops or there is no output if it can be composed of batteries, electric double-layer capacitors, etc. (paragraph [0029]). The power switching unit controls the flow of power supply in order to supply power to the end when there is the output voltage of the main power supply (paragraph [0030]). When the output of the main power supply is less than the threshold, it switches to the output from the backup power supply unit (paragraph [0030]). The controller section will perform power switching monitoring of the power switching section (paragraph [0031]). The wireless communication unit sends out the signals generated by the controller unit with radio waves, and sends the received signals to the controller unit (paragraph [0033]). In the wide-area monitoring system, the number of communications of the standby power operation slave station is suppressed. As a result, the consumption of the standby power supply can be suppressed, and the standby power operation slave station can maintain long-term communication (paragraph [0145]).

專利文獻1：日本特開2013-89978號公報Patent Document 1: JP 2013-89978 A

設置預備電源部於通訊終端，使通訊終端的成本增加，與使構築多重跳接式網路所需要的設備投資增加。然後，設置預備電源部於通訊終端所造成的通訊終端的成本的增加量，主要受到預備電源部所具備的電子儲藏器的容量影響。因此，可期待減少預備電源部所具備的電子儲藏器的容量。The provision of a backup power supply unit in the communication terminal increases the cost of the communication terminal and increases the equipment investment required to construct a multi-hop network. Then, the increase in the cost of the communication terminal caused by the provision of the backup power supply unit in the communication terminal is mainly affected by the capacity of the electronic storage provided in the backup power supply unit. Therefore, it can be expected to reduce the capacity of the electronic storage provided in the reserve power supply unit.

根據專利文獻1所記載的技術，因此預備電源的消費被抑制（段落第[0145]段），因此也可看見能夠減少構成預備電源部的電池、雙電層電容器等的容量。然而，專利文獻1所記載的技術中，系統電源發生大規模停電，子局的全部成為預備電源動作子局的情況下，預備電源動作子局必須進行主電源動作子局之前進行的通訊，而變得無法抑制預備電源動作子局的通訊次數。考慮到這點，並不一定能夠減少構成預備電源部的電池、雙電層電容器等的容量。According to the technology described in Patent Document 1, the consumption of the backup power source is suppressed (paragraph [0145]), and therefore, it can also be seen that the capacity of the battery, the electric double layer capacitor, and the like constituting the backup power source can be reduced. However, in the technique described in Patent Document 1, when a large-scale power failure occurs in the system power supply and all of the slave stations become the standby power operation slave stations, the standby power operation slave station must perform the communication that was carried out before the main power operation slave station. It becomes impossible to suppress the number of communications of the slave stations of the pre-power operation. Taking this into consideration, it is not always possible to reduce the capacity of batteries, electric double-layer capacitors, and the like that constitute the reserve power supply unit.

本發明是有鑑於這個問題而完成。本發明所要解決的問題是削減設置在構成多重跳接式網路的通訊終端上的預備電源部所具備的電力儲藏器的電容。The present invention has been completed in view of this problem. The problem to be solved by the present invention is to reduce the capacitance of a power storage device provided in a backup power supply unit provided on a communication terminal forming a multiple jumper network.

本發明適用於構成多重跳接式網路的通訊終端。The present invention is suitable for communication terminals forming a multiple jumper network.

通訊終端具備通常電源部、預備電源部、無線部、切換部及控制部。The communication terminal includes a normal power supply unit, a backup power supply unit, a wireless unit, a switching unit, and a control unit.

通常電源部供給電力系統供給的第1電力。Normally, the power supply unit supplies the first electric power supplied by the electric power system.

預備電源部具備電力儲藏器，預備電源部供給電力儲藏器所放電的第2電力。The backup power supply unit includes a power storage device, and the backup power supply unit supplies the second power discharged from the power storage device.

無線部與構成與多重跳接式網路的其他的通訊終端進行無線通訊。無線部將無線通訊的通訊速度切換於第1通訊速度、比第1通訊速度快的第2通訊速度之間。無線部將無線通訊發送出顯示出電子系統的發生停電之停電通知。The wireless part performs wireless communication with other communication terminals forming a multi-hop network. The wireless part switches the communication speed of wireless communication between the first communication speed and the second communication speed which is faster than the first communication speed. The wireless department sends out a power outage notification that shows the occurrence of a power outage in the electronic system through wireless communication.

切換部將使無線部動作的電力切換於第1電力及第2電力之間。The switching unit switches the power for operating the wireless unit between the first power and the second power.

控制部在檢測出電力系統的停電的情況下，讓切換部使無線部動作的電力從第1電力切換到第2電力，讓無線部將無線通訊的通訊速度從第1通訊速度切換至第2通訊速度，讓無線部發送停電通知。When the control unit detects a power failure in the power system, the switching unit switches the power for the wireless unit operation from the first power to the second power, and the wireless unit switches the communication speed of the wireless communication from the first communication speed to the second power. The communication speed allows the wireless department to send a power outage notice.

本發明也適用於多重跳接式網路。The present invention is also applicable to multi-hop network.

根據本發明，電力系統發生停電，無線部以電力儲藏器所放電的第2電力來動作的情況下，無線通訊的通訊速度從第1通訊速度加快到第2通訊速度，能夠縮短無線通訊所需要的時間。因此，能夠削減使無線部動作所需要的電力量，能夠削減電力儲藏器的容量。According to the present invention, when a power failure occurs in the power system and the wireless part operates with the second power discharged from the power storage, the communication speed of wireless communication is increased from the first communication speed to the second communication speed, which can shorten the wireless communication requirements. time. Therefore, the amount of power required to operate the wireless unit can be reduced, and the capacity of the power storage can be reduced.

本發明的目的、特徵、端點及優點藉由以下的詳細說明及圖式能夠更清楚。The purpose, features, endpoints and advantages of the present invention will be made clearer by the following detailed description and drawings.

1 實施型態1 1.1          多重跳接式網路 第1圖係概要顯示具備實施型態1的通訊終端之多重跳接式網路的概要圖。1 Implementation type 1 1.1 Multi-hop network Figure 1 is a schematic diagram showing a multi-hop network with a communication terminal of implementation type 1.

第1圖所示的多重跳接式網路1具備複數的通訊終端11、集約裝置12及母局13。The multi-hop network 1 shown in FIG. 1 includes a plurality of communication terminals 11, an aggregation device 12, and a home office 13.

複數的通訊終端11是4台通訊終端11a、11b、11c、11d，集約裝置12是1台集約裝置，母局13是1台母局。然而，多重跳接式網路1可以具備3台以下或者是5台以上的通訊終端，可具備2台以上的集約裝置，也可以具備2台以上的母局。The plural communication terminals 11 are four communication terminals 11a, 11b, 11c, and 11d, the intensive device 12 is one intensive device, and the parent station 13 is one parent station. However, the multi-hop network 1 can have 3 or less communication terminals, 5 or more communication terminals, 2 or more intensive devices, or 2 or more home offices.

複數的通訊終端11覆蓋單一的多重跳接式網路區域20。The plural communication terminals 11 cover a single multi-hop network area 20.

包含於複數的通訊終端11的各通訊終端11x能夠以第1通訊速度及第2通訊速度來進行無線通訊。第2通訊速度比第1通訊速度快，各通訊終端11x也能夠以彼此不同的3個以上的通訊速度來進行無線通訊。Each communication terminal 11x included in the plural communication terminals 11 can perform wireless communication at the first communication speed and the second communication speed. The second communication speed is faster than the first communication speed, and each communication terminal 11x can also perform wireless communication at 3 or more different communication speeds.

各通訊終端11x電性連接到電力系統30。藉此，各通訊終端11x藉由電力系統30所供給的第1電力來動作。又，各通訊終端11x具備下述的預備電源部，藉由下述的預備電源部所供給的第2電力動作。Each communication terminal 11x is electrically connected to the power system 30. Thereby, each communication terminal 11x is operated by the first power supplied from the power system 30. Moreover, each communication terminal 11x is equipped with the following backup power supply part, and is operated by the 2nd electric power supplied from the following backup power supply part.

通常時，複數的通訊終端11會以第1通訊速度彼此進行無線通訊。又，集約裝置12與複數的通訊終端11所包含的通訊終端11d進行無線通訊。又，母局13與集約裝置12進行通訊。藉此，集約裝置12取得由複數的通訊終端11分別發送的複數的資料，集約取得的複數的資料。母局13取得集約的複數的資料。母局13進行多重跳接式網路1的全體的管理、對各通訊終端11x的控制的分配。Normally, a plurality of communication terminals 11 will wirelessly communicate with each other at the first communication speed. In addition, the intensive device 12 performs wireless communication with the communication terminal 11d included in the plurality of communication terminals 11. In addition, the home office 13 communicates with the intensive device 12. Thereby, the aggregation device 12 obtains the plural data respectively transmitted by the plural communication terminals 11, and aggregates the obtained plural data. The home office 13 obtains intensive plural data. The parent office 13 performs overall management of the multi-hop network 1 and distribution of control to each communication terminal 11x.

1.2 通訊終端的通常時的發送動作 第2圖係實施型態1的通訊終端的發送資料時的動作的流程圖。1.2 Normal transmission operation of the communication terminal Figure 2 is a flow chart of the operation of the communication terminal of the implementation type 1 when sending data.

複數的通訊終端11所包含的各通訊終端11x在通常時，在第2圖所示的步驟S101，以接收狀態待機。又，各通訊終端11x在通常時，會在發送資料時進行第2圖所示的步驟S102至S105。又，各通訊終端11x在通常時，會在發送資料後在第2圖所示的步驟S106回到接收狀態。Each communication terminal 11x included in the plurality of communication terminals 11 waits in a receiving state in step S101 shown in FIG. 2 in the normal state. In addition, each communication terminal 11x normally performs steps S102 to S105 shown in FIG. 2 when transmitting data. In addition, each communication terminal 11x returns to the receiving state in step S106 shown in FIG. 2 after transmitting the data in the normal state.

在步驟S102，各通訊終端11x進行載波感測（CCA），根據CCA的結果來判定是否進入發送模式。各通訊終端11x判定能夠進入發送模式的情況，進行步驟S103。各通訊終端11x判定不能夠進入發送模式的情況，再次進行步驟S102。藉此，各通訊終端11x在能夠判定能夠進入發送模式為止，進行CCA，根據CCA的結果反覆地判定是否能夠進入發送模式。In step S102, each communication terminal 11x performs carrier sensing (CCA), and determines whether to enter the transmission mode according to the result of the CCA. Each communication terminal 11x determines that it can enter the transmission mode, and proceeds to step S103. When each communication terminal 11x determines that it cannot enter the transmission mode, step S102 is performed again. Thereby, each communication terminal 11x performs CCA until it can be determined that it can enter the transmission mode, and iteratively determines whether or not it can enter the transmission mode based on the result of the CCA.

在步驟S103，各通訊終端11x進入發送模式，藉由無線通訊來發送資料。各通訊終端11x藉由無線通訊來發送資料時，以第1通訊速度來進行無線通訊。In step S103, each communication terminal 11x enters a transmission mode, and transmits data through wireless communication. When each communication terminal 11x transmits data by wireless communication, it performs wireless communication at the first communication speed.

在接著的步驟S104，各通訊終端11x等待Acknowledgment（ACK）應答，判定是否接收ACK應答。ACK應答顯示資料正常發送。各通訊終端11x判定了接收了ACK應答的情況下，執行步驟S105。各通訊終端11x在判定沒有接收到ACK應答的情況下，再次進行步驟S102。藉此，各通訊終端11x在能夠判定接收到ACK應答為止，會藉由無線通訊反覆地發送資料。In the next step S104, each communication terminal 11x waits for an Acknowledgment (ACK) response, and determines whether or not to receive an ACK response. The ACK response shows that the data was sent normally. When each communication terminal 11x determines that it has received the ACK response, step S105 is executed. When each communication terminal 11x determines that it has not received an ACK response, step S102 is performed again. Thereby, each communication terminal 11x repeatedly transmits data through wireless communication until it can determine that it has received an ACK response.

在步驟S105，各通訊終端11x結束發送資料。In step S105, each communication terminal 11x finishes sending data.

各通訊終端11x在電力系統30停電時，在步驟S101以接收狀態待機，在發送資料時，執行步驟S102至S105，發送資料後，在步驟S106回到接收狀態。When the power system 30 is out of power, each communication terminal 11x waits in the receiving state in step S101, and performs steps S102 to S105 when sending data, and returns to the receiving state in step S106 after sending the data.

然而，各通訊終端11x在電子系統30停電時，以無線通訊發送資料時，以比第1通訊速度快的第2通訊速度進行無線通訊。藉此，各通訊終端11x在電子系統30停電時，比通常時更能夠縮短發送資料所需要的時間。一般來說，發送資料期間的各通訊終端11x的消耗電力大。因此，縮短發送資料所需要的時間會對削減發送資料期間的各通訊終端11x的消耗電力量有所幫助。因此，各通訊終端11x會在電力系統30停電時以比第1通訊速度更快的第2通訊速度進行無線通訊，藉此縮短發送資料所需要的時間，削減發送資料期間的各通訊終端11x的消耗電力量。However, each communication terminal 11x performs wireless communication at a second communication speed that is faster than the first communication speed when sending data through wireless communication when the electronic system 30 is out of power. Thereby, each communication terminal 11x can shorten the time required to transmit data more than usual when the electronic system 30 is out of power. Generally, the power consumption of each communication terminal 11x during data transmission is large. Therefore, shortening the time required to transmit the data helps to reduce the power consumption of each communication terminal 11x during the transmission of the data. Therefore, each communication terminal 11x will perform wireless communication at a second communication speed faster than the first communication speed when the power system 30 is out of power, thereby shortening the time required to transmit data and reducing the time required for each communication terminal 11x during data transmission. The amount of power consumed.

1.3 通訊終端 第3圖係顯示實施型態1的通訊終端的方塊圖。1.3 Communication terminal Fig. 3 is a block diagram showing the communication terminal of the first embodiment.

複數的通訊終端11所包含的各通訊終端11x構成多重跳接式網路1。Each communication terminal 11x included in the plural communication terminals 11 constitutes a multi-hop network 1.

各通訊終端11x如第3圖所示，具備通常電源部101、預備電源部102、切換部103、無線部104及控制部105。As shown in FIG. 3, each communication terminal 11x includes a normal power supply unit 101, a backup power supply unit 102, a switching unit 103, a wireless unit 104, and a control unit 105.

通常電源部101、預備電源部102及切換部103構成供給使無線部104及控制部105動作的電力之電源部111。Normally, the power supply unit 101, the standby power supply unit 102, and the switching unit 103 constitute a power supply unit 111 that supplies power for operating the wireless unit 104 and the control unit 105.

通常電源部101電性連接電力系統30。通常電源部101將電力系統30所供給的第1電力。Generally, the power supply unit 101 is electrically connected to the power system 30. Normally, the power supply unit 101 receives the first power supplied from the power system 30.

預備電源部102具備電力儲藏器121。預備電源部102藉由通常電源部101所供給的第1電力來對電力儲藏器121充電。又，預備電源部102供給電力儲藏器121所放電的第2電力。電力儲藏器121是雙電層電容器。電力儲藏器121也可以是雙電層電容器以外的電力儲藏器。例如，電力儲藏器121也可以是蓄電池。The reserve power supply unit 102 includes a power storage 121. The backup power supply unit 102 charges the power storage 121 with the first power supplied from the normal power supply unit 101. In addition, the backup power supply unit 102 supplies the second power discharged from the power storage 121. The power storage 121 is an electric double layer capacitor. The power storage 121 may be a power storage other than an electric double layer capacitor. For example, the power storage 121 may also be a storage battery.

切換部103將使無線部104及控制部105動作的電力切換於通常電源部101所供給的第1電力、以及由預備電源部102所供給的第2電力之間。切換部103也可以藉由具備繼電器等的開關元件之硬體來實現，也可以藉由軟體控制來實現。The switching unit 103 switches the power for operating the wireless unit 104 and the control unit 105 between the first power supplied by the normal power supply unit 101 and the second power supplied by the backup power supply unit 102. The switching unit 103 may also be realized by hardware provided with switching elements such as a relay, or may be realized by software control.

無線部104與構成多重跳接式網路1的其他的通訊終端進行無線通訊。無線部104能夠將無線通訊的通訊速度切換在第1通訊速度及第2通訊速度之間。第2通訊速度比第1通訊速度快。無線部104以無線通知來發送顯示出電力系統30發生停電的停電通知。The wireless unit 104 performs wireless communication with other communication terminals constituting the multi-hop network 1. The wireless unit 104 can switch the communication speed of wireless communication between the first communication speed and the second communication speed. The second communication speed is faster than the first communication speed. The wireless unit 104 transmits a power failure notification indicating that a power failure has occurred in the power system 30 by wireless notification.

控制部105控制無線部104及切換部103，儲存資料。The control unit 105 controls the wireless unit 104 and the switching unit 103 to store data.

控制部105在通常時及各通訊終端11x的啟動時，讓切換部103將使無線部104及控制部105動作的電力設定成通常電源部101所供給的第1電力，讓無線部104將無線通訊的通訊速度設定成第1通訊速度。又，控制部105在電力系統30停電時，讓切換部103將使無線部104及控制部105動作的電力設定成預備電源部102所供給的第2電力，讓無線部104將無線通訊的通訊速度設定成第2通訊速度。因此，控制部105檢測出電力系統30停電時，讓切換部103將使無線部104及控制部105動作的電力從第1電力切換成第2電力，讓無線部104將無線通訊的通訊速度從第1通訊速度切換到第2通訊速度。The control section 105 causes the switching section 103 to set the power for operating the wireless section 104 and the control section 105 to the first power supplied by the normal power supply section 101 during the normal time and when each communication terminal 11x is activated, and the wireless section 104 to set the wireless The communication speed of communication is set to the first communication speed. In addition, when the power system 30 is out of power, the control unit 105 causes the switching unit 103 to set the power for operating the wireless unit 104 and the control unit 105 to the second power supplied by the standby power supply unit 102, and the wireless unit 104 communicates wirelessly. The speed is set to the second communication speed. Therefore, when the control unit 105 detects a power failure in the power system 30, it causes the switching unit 103 to switch the power for operating the wireless unit 104 and the control unit 105 from the first power to the second power, so that the wireless unit 104 changes the communication speed of the wireless communication from The first communication speed is switched to the second communication speed.

又，控制部105在檢測出電力系統30停電的情況下，讓無線部104發送停電通知。In addition, when the control unit 105 detects a power failure in the power system 30, it causes the wireless unit 104 to transmit a power failure notification.

又，控制部105在通常時及各通訊終端11x的啟動時，將各通訊終端11x設定為通常通作模式。又，控制部105在電力系統30的停電時，將各通訊終端11x設定為低消耗電力模式。因此，控制部105在檢測出電力系統30停電的情況下，將各通訊終端11x從通常動作模式移動到低消耗電力模式。通常動作模式是不限制各通訊終端11x的功能的第1模式。低消耗電力模式是各通訊終端11x的功能被限制最小限，具有比通常動作模式的消耗電力更低的消耗電力的第2模式。將各通訊終端11x的功能限制於最小限，例如包含遮斷進行無線通訊以外的通訊的外部介面。In addition, the control unit 105 sets each communication terminal 11x to the normal operation mode during normal time and when each communication terminal 11x is activated. In addition, the control unit 105 sets each communication terminal 11x to the low power consumption mode at the time of a power failure of the power system 30. Therefore, when the control unit 105 detects a power failure in the power system 30, it moves each communication terminal 11x from the normal operation mode to the low power consumption mode. The normal operation mode is the first mode that does not restrict the function of each communication terminal 11x. The low power consumption mode is a second mode in which the function of each communication terminal 11x is restricted to a minimum, and the power consumption is lower than that of the normal operation mode. The function of each communication terminal 11x is limited to a minimum, for example, it includes an external interface that interrupts communication other than wireless communication.

1.4 電力系統的停電時的通訊終端的控制程序 第4圖及第5圖係顯示實施型態1的通訊終端在電力系統的停電時的控制程序的流程圖。1.4 The control program of the communication terminal when the power system is out of power Figures 4 and 5 are flowcharts showing the control procedure of the communication terminal of Embodiment 1 when the power system is out of power.

第4圖所示的步驟S111至S115為止，是對電力系統30的停電進行準備的停電準備步驟。第4圖所示的步驟S116至S120為止，是通知電力系統30發生停電的停電通知步驟。第5圖所示的步驟S121至S124為止，是對電力系統30的復電進行準備的復電準備步驟。Steps S111 to S115 shown in FIG. 4 are power failure preparation steps to prepare for a power failure of the power system 30. Steps S116 to S120 shown in FIG. 4 are power failure notification steps for notifying the power system 30 that a power failure has occurred. Steps S121 to S124 shown in FIG. 5 are power recovery preparation steps for preparing power system 30 for power recovery.

在步驟S111，控制部105檢測出電力系統30的停電。In step S111, the control unit 105 detects a power failure of the power system 30.

在接著的步驟S112，控制部105控制切換部103。切換部103按照控制部105所進行的控制，將使無線部104及控制部105動作的電力，從通常電源部101所供給的第1電力切換成預備電源部102所供給的第2電力。In the next step S112, the control unit 105 controls the switching unit 103. The switching unit 103 switches the power for operating the wireless unit 104 and the control unit 105 from the first power supplied by the normal power supply unit 101 to the second power supplied by the backup power supply unit 102 in accordance with the control performed by the control unit 105.

在接著的步驟S113，控制部105控制無線部104。無線部104按照控制部105所進行的控制，將無線通訊的通訊速度從第1通訊速度切換成第2通訊速度。藉此，在停電通知步驟，以第2通訊速度進行無線通訊。In the next step S113, the control unit 105 controls the wireless unit 104. The wireless unit 104 switches the communication speed of wireless communication from the first communication speed to the second communication speed in accordance with the control performed by the control unit 105. Thereby, in the power failure notification step, wireless communication is performed at the second communication speed.

在接著的步驟S114，控制部105設定重置計數器。藉此，開始測量使無線部104及控制部105動作的電力從通常電源部101所供給的第1電力切換到預備電源部102所供給的第2電力後所經過的時間T。又，經過的時間T到達設定的時間Ts的情況下，發生各通訊終端11x的自我重置。設定的時間Ts是因應於各通訊終端11x的納入目的地所要求的規格所決定的固定值。In the next step S114, the control unit 105 sets a reset counter. Thereby, measurement of the time T elapsed after the power for operating the wireless unit 104 and the control unit 105 is switched from the first power supplied by the normal power supply unit 101 to the second power supplied by the backup power supply unit 102 is started. Also, when the elapsed time T reaches the set time Ts, self-reset of each communication terminal 11x occurs. The set time Ts is a fixed value determined in accordance with the specifications required by the acceptance destination of each communication terminal 11x.

步驟S113及S114所執行的順序也可以變更。The order in which steps S113 and S114 are executed can also be changed.

在接著的步驟S115，控制部105是各通訊終端11x從通常動作模式移動到低消耗電力模式。In the next step S115, the control unit 105 moves each communication terminal 11x from the normal operation mode to the low power consumption mode.

在接著的步驟S116，控制部105控制無線部104。無線部104依據控制部105所進行的控制，執行CCA。又，控制部105根據CCA的結果，判定能否移動到發送模式。判定能夠進入到發送模式的情況下，執行步驟S117。判定不能夠進入到發送模式的情況下，再次執行步驟S116。In the next step S116, the control unit 105 controls the wireless unit 104. The wireless unit 104 executes CCA in accordance with the control performed by the control unit 105. In addition, the control unit 105 determines whether it is possible to move to the transmission mode based on the result of the CCA. When it is determined that the transmission mode can be entered, step S117 is executed. If it is determined that the transmission mode cannot be entered, step S116 is executed again.

在步驟S117，控制部105控制無線部104。無線部104依據控制部105的控制，進入發送模式，藉由無線通訊來發送停電通知。要發送的停電通知顯示電子系統30發生停電。In step S117, the control unit 105 controls the wireless unit 104. The wireless unit 104 enters the transmission mode under the control of the control unit 105, and transmits a power failure notification through wireless communication. The power failure notification to be sent indicates that the electronic system 30 has a power failure.

在接著的步驟S118，控制部105控制無線部104。無線部104根據控制部105所進行的控制，前進到接收模式。In the next step S118, the control unit 105 controls the wireless unit 104. The wireless unit 104 proceeds to the reception mode in accordance with the control performed by the control unit 105.

在接著的步驟S119，控制部105控制無線部104。無線部104依據控制部105的控制，等待ACK回答。又，控制部105判定是否接收了ACK回答。判定了接收了ACK回答的情況下，進行步驟S120。判定不接收了ACK回答的情況下，再次進行步驟S116。In the next step S119, the control unit 105 controls the wireless unit 104. The wireless unit 104 waits for an ACK response under the control of the control unit 105. In addition, the control unit 105 determines whether or not an ACK response has been received. When it is determined that the ACK response is received, step S120 is performed. If it is determined that the ACK response is not received, step S116 is performed again.

在接著的步驟S120，控制部105讓各通訊終端11x進入低消耗電力模式。In the next step S120, the control unit 105 causes each communication terminal 11x to enter the low power consumption mode.

在接著的步驟S121，經過的時間T達到設定的時間Ts，發生各通訊終端11x的自我重置。控制部105在此時控制切換部103。切換部103根據控制部105的控制，將使無線部104及控制部105動作的電力，從預備電源部102所供給的第2電力切換成通常電源部101所供給的第1電力。In the next step S121, the elapsed time T reaches the set time Ts, and the self-reset of each communication terminal 11x occurs. The control unit 105 controls the switching unit 103 at this time. The switching unit 103 switches the power for operating the wireless unit 104 and the control unit 105 from the second power supplied by the backup power supply unit 102 to the first power supplied by the normal power supply unit 101 under the control of the control unit 105.

在接著的步驟S122以後，各通訊終端11x的狀態因應電子系統30復電與否而變化。電子系統30復電的情況下，在步驟S123，各通訊終端11x啟動。電子系統30沒有復電的情況下，在步驟S124，各通訊終端11x的電源維持關閉。After the following step S122, the state of each communication terminal 11x changes according to whether the electronic system 30 is re-powered or not. When the electronic system 30 is powered back, in step S123, each communication terminal 11x is activated. If the electronic system 30 is not re-powered, in step S124, the power of each communication terminal 11x is kept off.

1.5 通訊終端的消耗電力的時間變化 第6圖係顯示實施型態1的通訊終端的消耗電力的時間變化的流程圖。第6圖（a）是以第1通訊速度進行無線通訊的情況下的流程圖。第6圖（b）是以第2通訊速度進行無線通訊的情況下的流程圖。1.5 Time change of power consumption of communication terminal Fig. 6 is a flowchart showing the temporal change of the power consumption of the communication terminal according to the first embodiment. Figure 6(a) is a flowchart in the case of wireless communication at the first communication speed. Figure 6(b) is a flowchart in the case of wireless communication at the second communication speed.

第6圖（a）及第6圖（b）顯示各通訊終端11x發送1次停電通知的情況下，各通訊終端11x的消耗電力的時間變化。Fig. 6(a) and Fig. 6(b) show the time change of the power consumption of each communication terminal 11x when each communication terminal 11x transmits a power outage notification once.

如第6圖（a）及第6圖（b）所示，各通訊終端11x被設定在通常動作模式的期間131中的各通訊終端11x的消耗電力是Pa [W]。又，各通訊終端11x被設定在低消耗電力模式的期間132中的各通訊終端11x的消耗電力是Pe [W]。又，無線部104執行CCA期間113中的各通訊終端11x的消耗電力是Pc [W]。又，無線部104發送停電通知的期間134中的各通訊終端11x的消耗電力是Pb [W]。又，無線部104接收ACK回答的期間135中的各通訊終端11x的消耗電力是Pd [W]。消耗電力Pa 、Pb 、Pc 、Pd 、Pe 會滿足的Pa >Pb >Pc >Pd >Pe >0關係。As FIG section 6 (a) and FIG.6 (b), each of the communication terminals 11x are set at 131 during the normal operation mode of the power consumption of each communication terminal 11x is P a [W]. In addition, the power consumption of each communication terminal 11x during the period 132 in which each communication terminal 11x is set in the low power consumption mode is P e [W]. In addition, the power consumption of each communication terminal 11x during the CCA period 113 performed by the wireless unit 104 is P c [W]. In addition, the power consumption of each communication terminal 11x in the period 134 during which the wireless unit 104 transmits the power failure notification is P b [W]. In addition, the power consumption of each communication terminal 11x in the period 135 during which the wireless unit 104 receives the ACK response is P d [W]. The power consumption P a , P b , P c , P d , and P e will satisfy the relationship P a >P b >P c >P d >P e >0.

又，如第6圖（a）及第6圖（b）所示，即使是以第1通訊速度進行無線通訊的情況，以及以第2無線通訊速度進行無線通訊的情況的任一者，期間132、133、134及135的長度的合計是Ts [sec]。又，以第1通訊速度進行無線通訊的情況下，期間133的長度是TCCA [sec]，期間134及135的長度分別是TTX [sec]及TRX [sec]。又，以第2通訊速度進行無線訊的情況下，期間133的長度是TCCA [sec]，期間134及135的長度分別比TTX 及TRX [sec]短。因此，藉由將無線通訊的速度切換成第1通訊速度及第2通訊速度，能夠縮短進行無線通訊的期間134及135的長度的合計。例如，第1通訊速度是100kbps，第2通訊速度是200kbps的情況下，進行無線通訊的期間134及135的長度的合計能夠從（TTX + TRX ）[sec]縮短成（TTX + TRX ）/2[sec]。更一般地，第2通訊速度是第1通訊速度的N倍的情況下，進行無線通訊的期間134及135的長度的合計能夠從（TTX + TRX ）[sec]縮短成（TTX + TRX ）/N[sec]。藉此，能夠削減無線通訊所使用的電力量。Also, as shown in Fig. 6(a) and Fig. 6(b), even if the wireless communication is performed at the first communication speed and the wireless communication is performed at the second wireless communication speed, the period The total length of 132, 133, 134, and 135 is T s [sec]. Furthermore, when wireless communication is performed at the first communication speed, the length of the period 133 is T CCA [sec], and the lengths of the periods 134 and 135 are T TX [sec] and T RX [sec], respectively. In addition, when wireless communication is performed at the second communication speed, the length of the period 133 is T CCA [sec], and the lengths of the periods 134 and 135 are shorter than T TX and T RX [sec], respectively. Therefore, by switching the wireless communication speed to the first communication speed and the second communication speed, the total length of the periods 134 and 135 during which the wireless communication is performed can be shortened. For example, when the first communication speed is 100kbps and the second communication speed is 200kbps, the total length of the wireless communication period 134 and 135 can be shortened from (T TX + T RX ) [sec] to (T TX + T RX )/2[sec]. More generally, when the second communication speed is N times the first communication speed, the total length of the wireless communication period 134 and 135 can be shortened from (T TX + T RX ) [sec] to (T TX + T RX )/N[sec]. As a result, the amount of power used for wireless communication can be reduced.

1.6 電力儲藏器的靜電電容的削減量 電力儲藏器121的靜電電容C會使用電荷Q、電力儲藏器121的電壓降V、消耗電流I、動作時間T及消耗電力P，以式（1）表示。式（1）是由電荷公式及歐姆法則所得。1.6 The amount of reduction in the electrostatic capacitance of the power storage device The electrostatic capacitance C of the power storage 121 uses the charge Q, the voltage drop V of the power storage 121, the current consumption I, the operating time T, and the power consumption P, which are expressed by equation (1). Equation (1) is derived from the charge formula and Ohm's law.

電力儲藏器121的電壓降V是使用通常電源電壓Vin [V]及各通訊終端11x的最低動作電壓Vlow [V]，以式（2）表示。The voltage drop V of the power storage 121 uses the normal power supply voltage V in [V] and the lowest operating voltage V low [V] of each communication terminal 11x, which is expressed by equation (2).

[算式2] V＝Vin －Vlow …（2）[Equation 2] V=V in －V low …(2)

電力儲藏器121的靜電電容C的削減量C’[F]是以第1通訊速度進行無線通訊時提供進行無線通訊的期間134及135中的各通訊終端11x的消耗電力量所必須的靜電電容，減去以第2通訊速度進行無線通訊時提供進行無線通訊的期間134及135中的各通訊終端11x的消耗電力量所必須的靜電電容、以及提供具有與各通訊終端11x被設定在低消耗電力模式的情況的進行無線通訊的期間134及135的長度的縮短量一致的長度的期間中的各通訊終端11x的消耗電力量的必要靜電電容而得。因此，電力儲藏器121的靜電電容C的削減量C’是以式（3）表示。The reduction amount C'[F] of the electrostatic capacitance C of the power storage 121 is the electrostatic capacitance necessary to provide the power consumption of each communication terminal 11x during the wireless communication period 134 and 135 when wireless communication is performed at the first communication speed. , Minus the electrostatic capacitance necessary to provide the power consumption of each communication terminal 11x in the wireless communication period 134 and 135 when wireless communication is performed at the second communication speed, and provide a low power consumption with each communication terminal 11x. In the case of the power mode, the length of the periods 134 and 135 during which the wireless communication is performed is reduced by the same length as the required electrostatic capacitance of the power consumption of each communication terminal 11x. Therefore, the reduction amount C'of the electrostatic capacitance C of the power storage 121 is expressed by the formula (3).

[算式3]

第2通訊速度是第1通訊速度的N倍的情況下，以第2通訊速度進行無線通訊時提供進行無線通訊的期間134及135的長度分別是以第1通訊速度進行無線通訊時提供進行無線通訊的期間134及135的長度的N分之一。因此，以第2通訊速度進行無線通訊時提供進行無線通訊的期間134及135中的各通訊終端11x的消耗電力量是以第1通訊速度進行無線通訊時提供進行無線通訊的期間134及135中的各通訊終端11x的消耗電力量的N分之一。因此，以式（3）所表示的電力儲藏器121的靜電電容C的削減量C’會取正值。When the second communication speed is N times the first communication speed, the lengths of the period 134 and 135 are provided for wireless communication when wireless communication is performed at the second communication speed. One Nth of the length of the communication period 134 and 135. Therefore, when wireless communication is performed at the second communication speed, the power consumption of each communication terminal 11x during the wireless communication period 134 and 135 is provided during the wireless communication period 134 and 135 when the wireless communication is performed at the first communication speed. One Nth of the power consumption of each communication terminal 11x. Therefore, the reduction amount C'of the electrostatic capacitance C of the power storage 121 expressed by the formula (3) takes a positive value.

1.7 實施型態1的發明的效果 根據實施型態1的發明，電力系統30發生停電而藉由電力儲藏器121所放電的第2電力使無線部104動作的情況下，無線通訊的通訊速度從第1通訊速度加快至第2通訊速度，能夠縮短無線通訊所需要的時間。因此，能夠削減使無線部104動作所必要的電力量，能夠削減電力儲藏器121的電容。1.7 Effect of the invention of implementation type 1 According to the invention of the first embodiment, when a power failure occurs in the power system 30 and the wireless unit 104 is activated by the second power discharged from the power storage 121, the communication speed of the wireless communication is increased from the first communication speed to the second communication Speed can shorten the time required for wireless communication. Therefore, the amount of electric power necessary to operate the wireless unit 104 can be reduced, and the capacitance of the power storage 121 can be reduced.

2 實施型態2 2.1 前言 第2圖係實施型態2的通訊終端的發送資料時的動作的流程圖。第3圖係顯示實施型態2的通訊終端的方塊圖。第4圖及第5圖係顯示實施型態2的通訊終端在電力系統的停電時的控制程序的流程圖。第6圖係顯示實施型態2的通訊終端的消耗電力的時間變化的流程圖。2 Implementation type 2 2.1 Preface Figure 2 is a flow chart of the operation of the communication terminal in the second embodiment when sending data. Figure 3 is a block diagram showing the communication terminal of the second embodiment. Figures 4 and 5 are flowcharts showing the control procedure of the communication terminal of the second embodiment when the power system is out of power. Fig. 6 is a flowchart showing the time change of the power consumption of the communication terminal according to the second embodiment.

實施型態2主要是以下的點與實施型態1不同。關於未於下述的點，與實施型態1中採用的架構相同的架構也會在實施型態2中採用。Implementation Type 2 is mainly different from Implementation Type 1 in the following points. Regarding the points not described below, the same architecture as that adopted in the first embodiment will also be adopted in the second embodiment.

2.2 通訊終端 第7圖係顯示構成具備實施型態2的通訊終端之多重跳接式網路的複數的通訊終端的通常時的通訊路徑。第8圖顯示構成具備實施型態2的通訊終端之多重跳接式網路的複數的通訊終端的電力系統停電時的通訊路徑。2.2 Communication terminal Fig. 7 shows a communication path of a plurality of communication terminals constituting a multi-hop network with communication terminals of the second embodiment in normal time. Fig. 8 shows the communication path of the power system when the power system is powered off by the plural communication terminals that constitute the multi-hop network with the communication terminal of the embodiment 2.

複數的通訊終端11如第7圖及第8圖所示，具備通訊終端CT1-CT10。The plural communication terminals 11 are provided with communication terminals CT1-CT10 as shown in Figs. 7 and 8.

2.3 通訊路徑的切換 通訊終端CT1-CT10所包含的各通訊終端CTx具備的控制部105會儲存設定值，這些設定值定義出構成多重跳接式網路1的通訊終端CT1-CT10的通訊路徑。又，控制部105在檢測出電力系統30的停電時，將該設定值從通常的設定值切換到電力系統30停電時的設定值。通常的設定值是將通訊終端CT1-CT10的通訊路徑設定為第7圖所示的通常的通訊路徑的第1設定值。電力系統30停電時的設定值是將通訊終端CT1-CT10的通訊路徑設定為第8圖所示的電力系統30停電時的通訊路徑的第2設定值。第8圖所示的電力系統30停電時的通訊路徑與第7圖所示的通常的通訊路徑不同。2.3 Switching of communication path The control section 105 of each communication terminal CTx included in the communication terminals CT1 to CT10 stores the setting values, which define the communication paths of the communication terminals CT1 to CT10 constituting the multi-hop network 1. In addition, when the control unit 105 detects a power outage of the power system 30, the set value is switched from the normal setting value to the set value when the power system 30 is out of power. The normal setting value is to set the communication path of the communication terminals CT1-CT10 to the first setting value of the normal communication path shown in Fig. 7. The setting value at the time of power failure of the power system 30 is the second setting value of the communication path when the power system 30 is shown in FIG. 8 is set to the communication path of the communication terminals CT1-CT10. The communication path when the power system 30 shown in FIG. 8 fails is different from the normal communication path shown in FIG. 7.

通訊終端CT1-CT10的通訊路徑是第8圖所示的電力系統30的停電時的通訊路徑的情況下，與通訊終端CT1-CT10的通訊路徑是第7圖所示的通常的通訊路徑的情況相比，無線通訊的通訊距離縮短。藉此，即使是無線通訊的通訊速度從第1通訊速度切換到第2通訊速度使得無線通訊的可通訊距離縮短的情況下，也能夠抑制無法無線通訊的情況。又，能夠抑制CCA發生失敗，能夠縮短CCA縮需要的時間。因此，能夠更進一步削減各通訊終端11x的消耗電力量。When the communication path of the communication terminals CT1-CT10 is the communication path during a power outage of the power system 30 shown in Fig. 8, the communication path with the communication terminals CT1-CT10 is the normal communication path shown in Fig. 7 In comparison, the communication distance of wireless communication is shortened. Thereby, even when the communication speed of the wireless communication is switched from the first communication speed to the second communication speed and the communication distance of the wireless communication is shortened, the situation that the wireless communication cannot be communicated can be suppressed. In addition, the failure of CCA can be suppressed, and the time required for CCA reduction can be shortened. Therefore, the power consumption of each communication terminal 11x can be further reduced.

各通訊終端11x所儲存的設定值是顯示從各通訊終端11x發送資料到集約裝置12所需要的跳躍數的數值。以下，將該數值稱為rank。各通訊終端11x在通常時會以無線通訊將資料發送到儲存比各通訊終端11x所儲存的rank更上位的rank的通訊終端。The setting value stored in each communication terminal 11x is a numerical value showing the number of hops required to send data from each communication terminal 11x to the intensive device 12. Hereinafter, this numerical value is referred to as rank. Each communication terminal 11x normally transmits data by wireless communication to a communication terminal storing a higher rank than the rank stored in each communication terminal 11x.

2.5 電力系統的停電時的通訊路徑 如第8圖所示，電力系統30停電時，被付與終端編號「10」的通訊終端CT10會將資料發送到被付與終端編號「6」的通訊終端CT6。又，被付與終端編號「6」的通訊終端CT6會將資料發送到被付與終端編號「7」的通訊終端CT7。又，被付與終端編號「7」的通訊終端CT7會將資料發送到被付與終端編號「8」的通訊終端CT8。又，被付與終端編號「8」的通訊終端CT8會將資料發送到被付與終端編號「9」的通訊終端CT9。又，被付與終端編號「9」的通訊終端CT9會將資料發送到被付與終端編號「5」的通訊終端CT5。又，被付與終端編號「5」的通訊終端CT5會將資料發送到被付與終端編號「4」的通訊終端CT4。又，被付與終端編號「4」的通訊終端CT4會將資料發送到被付與終端編號「3」的通訊終端CT3。又，被付與終端編號「3」的通訊終端CT3會將資料發送到被付與終端編號「1」的通訊終端CT1。又，被付與終端編號「1」的通訊終端CT1會將資料發送到被付與終端編號「2」的通訊終端CT2。又，被付與終端編號「2」的通訊終端CT2會將資料發送到集約裝置12。藉此，電力系統30停電時的通訊路徑無分枝，成為串珠狀的第2通訊路徑。成為電力系統30停電時的通訊路徑的起點之通訊終端是具有最下位rank的通訊終端。例如，成為起點的通訊終端是被付與rank「4」的通訊終端CT10。2.5 The communication path in the event of a power outage in the power system As shown in Fig. 8, when the power system 30 loses power, the communication terminal CT10 assigned the terminal number "10" will send data to the communication terminal CT6 assigned the terminal number "6". Also, the communication terminal CT6 assigned the terminal number "6" will send the data to the communication terminal CT7 assigned the terminal number "7". Also, the communication terminal CT7 assigned the terminal number "7" will send the data to the communication terminal CT8 assigned the terminal number "8".

Thereby, the communication path at the time of power failure of the power system 30 is not branched, and becomes a beaded second communication path. The communication terminal that becomes the starting point of the communication path when the power system 30 is out of power is the communication terminal with the lowest rank. For example, the communication terminal that becomes the starting point is the communication terminal CT10 assigned a rank of "4".

2.6 電力系統的停電時的處理的程序 第10圖及第11圖係顯示具備實施型態2的通訊終端之多重跳接式網路中在電力系統停電時所進行的處理程序之程序圖。2.6 Procedures for handling power outages in the power system Figures 10 and 11 are process diagrams showing the processing procedures performed when the power system is out of power in a multiple jumper network equipped with a communication terminal of implementation type 2.

電力系統30發生停電時，複數的通訊終端CT1-CT10的通訊路徑成為第8圖所示的電力系統30的停電時的通訊路徑。When a power failure occurs in the power system 30, the communication paths of the plurality of communication terminals CT1 to CT10 become the communication paths at the time of the power failure of the power system 30 shown in FIG. 8.

又，成為起點的通訊終端CT10所具備的無線部104，如第11圖所示，藉由無線通訊將顯示出電力系統30發生停電的停電通知BN10發送到下一個通訊終端CT6。又，成為起點的通訊終端CT10以及成為終點的通訊終端CT2以外的成為中繼器的各通訊終端CTj所具備的無線部104，如第10圖所示，在接收狀態等待停電通知BNi從前一個通訊終端CTi送來，在接受狀態等待期間以無線通訊從前一個通訊終端CTi接收停電通知BNi。又，成為中繼器的各通訊終端CTj所具備的無線部104，以無線通訊從前一個通訊終端CTi接收到停電通知BNi後，以無線通訊將停電通知BNj發送到下一個通訊終端CTk。又，成為終點的通訊終端CT2所具備的無線部104，在接收狀態等待停電通知BN1從前一個通訊終端CT1送來，在接受狀態等待期間以無線通訊從前一個通訊終端CT1接收停電通知BN1。又，成為終點的通訊終端CT2所具備的無線部104，以無線通訊從前一個通訊終端CT1接收到停電通知BN1後，以無線通訊將停電通知BN2發到集約裝置12。In addition, the wireless unit 104 included in the communication terminal CT10 that is the starting point transmits a power failure notification BN10 indicating that a power failure has occurred in the power system 30 to the next communication terminal CT6 by wireless communication, as shown in FIG. 11. In addition, the wireless unit 104 of each communication terminal CTj that is a repeater other than the communication terminal CT10 that becomes the starting point and the communication terminal CT2 that becomes the end point, as shown in Fig. 10, is in the receiving state and waits for the power failure notification BNi to communicate from the previous one. The terminal CTi sends it to receive the power failure notification BNi from the previous communication terminal CTi by wireless communication during the waiting period of the receiving state. In addition, the wireless unit 104 included in each communication terminal CTj serving as a repeater receives the power failure notification BNi from the previous communication terminal CTi by wireless communication, and then transmits the power failure notification BNj to the next communication terminal CTk by wireless communication. Furthermore, the wireless unit 104 included in the communication terminal CT2 that is the destination waits for the power failure notification BN1 to be sent from the previous communication terminal CT1 in the receiving state, and receives the power failure notification BN1 from the previous communication terminal CT1 by wireless communication during the reception state waiting period. Furthermore, the wireless unit 104 included in the communication terminal CT2 that is the destination receives the power failure notification BN1 from the previous communication terminal CT1 by wireless communication, and then transmits the power failure notification BN2 to the centralized device 12 by wireless communication.

After receiving the power failure notification BNi, the terminal CTi stops the wireless unit 104 and waits in the receiving state. In addition, the control unit 105 included in the communication terminal CT2 that is the destination causes the wireless unit 104 to wait in the receiving state from the time when the power system 30 has a power failure. After receiving the power failure notification BN1, the wireless unit 104 is stopped and waits in the receiving state.

成為中繼器的各通訊終端CTj所具備的無線部104，將從前一的通訊終端CTi接收的停電通知BNi所含的資料，包含到要發送到下一個通訊終端CTk的停電通知BNj。The wireless unit 104 included in each communication terminal CTj serving as a repeater includes the data contained in the power failure notification BNi received from the previous communication terminal CTi, and includes the power failure notification BNj to be sent to the next communication terminal CTk.

多重跳接式網路1中，為了決定等待時間W1-W9，在通常時發生電力系統30的模擬停電。發生的電力系統30的模擬停電不會伴隨電力系統30的實際的停電。In the multi-hop network 1, in order to determine the waiting time W1-W9, a simulated power failure of the power system 30 occurs in normal times. The occurrence of the simulated power failure of the power system 30 will not be accompanied by the actual power failure of the power system 30.

發生電力系統30的模擬停電時，與電力系統30發生停電的情況相同，複數的通訊終端CT1-CT10的通訊路徑為成為第8圖所示的電力系統30的停電時的通訊路徑。When a simulated power outage of the power system 30 occurs, as in the case of a power outage of the power system 30, the communication paths of the plural communication terminals CT1 to CT10 become the communication paths when the power system 30 shown in FIG. 8 is out of power.

CT5, CT9, CT8, CT7, and CT6 are sent to the communication terminal CT10 which is the starting point. In addition, the wireless unit 104 included in the communication terminal CT10 that is the starting point receives the simulated power failure occurrence notification SBSN through wireless communication. In addition, the wireless unit 104 included in the communication terminal CT10, which is the starting point, as shown in FIG. 13, after receiving the simulated power failure notification SBSN from the centralized device 12 through wireless communication, it will display the simulated power system 30 occurrence of a simulated power failure through wireless communication. The power failure notification SBN10 is sent to the next communication terminal CT6. Furthermore, as shown in FIG. 12, the wireless unit 104 included in each communication terminal CTj serving as a repeater receives the simulated power failure occurrence notification SBNi from the previous communication terminal CTi by wireless communication. In addition, the wireless unit 104 of each communication terminal CTj serving as a repeater receives the analog power failure notification SBNi from the previous communication terminal CTi by wireless communication, and transmits the analog power failure notification SBNj to the next communication terminal CTk by wireless communication. In addition, the communication terminal CT2, which is the destination, receives the simulated power failure occurrence notification SBN1 from the previous communication terminal CT1 through wireless communication. In addition, after the communication terminal CT2, which is the destination, receives the simulated power failure notification SBN1 from the previous communication terminal CT1 through wireless communication, it transmits the simulated power failure notification SBN2 to the centralized device 12 through wireless communication.

成為起點的通訊終端CT10在將模擬停電通知SBN10發送到下一個通訊終端CT6時，會將發生模擬停電的停電發生時刻Tp包含到模擬停電通知SBN10中。停電發生時刻Tp是成為起點的通訊終端CT10接收到模擬停電發生通知SBSN的時刻。When the communication terminal CT10 serving as the starting point transmits the simulated power failure notification SBN10 to the next communication terminal CT6, the power failure occurrence time Tp at which the simulated power failure occurred is included in the simulated power failure notification SBN10. The power outage occurrence time Tp is the time when the communication terminal CT10, which is the starting point, receives the simulated power outage occurrence notification SBSN.

The reception start time difference 184 included in the comparison table 171 is the above-mentioned ΔT6=Tp-T10, ΔT7=Tp-T6, ΔT8=Tp-T7, ΔT9=Tp-T8, ΔT5=Tp-T9, ΔT4=Tp-T5, ΔT3=Tp-T4, ΔT1=Tp-T3, and ΔT2=Tp-T1.

集約裝置12如第12圖所示，以無線通訊向成為終點的通訊終端CT2發送等待時間資訊WI2。又，成為終點的通訊終端CT2以無線通訊從集約裝置12接收等待時間資訊WI2。又，成為終點的通訊終端CT2及成為起點的通訊終端CT10以外的成為中繼器的各通訊終端CTj以無線通訊從前一個通訊終端CTk接收等待時間資訊WIj。又，成為中繼器的各通訊終端CTj以無線通訊向下一個通訊終端CTi發送等待時間資訊WIi。As shown in FIG. 12, the intensive device 12 transmits the waiting time information WI2 to the communication terminal CT2, which is the destination, by wireless communication. In addition, the communication terminal CT2, which is the destination, receives the waiting time information WI2 from the aggregation device 12 by wireless communication. In addition, each communication terminal CTj serving as a repeater other than the communication terminal CT2 which is the destination and the communication terminal CT10 which is the starting point receives the waiting time information WIj from the previous communication terminal CTk by wireless communication. In addition, each communication terminal CTj that becomes a repeater transmits the waiting time information WIi to the next communication terminal CTi by wireless communication.

等待時間資訊WI2包括接收開始時刻差ΔT6、ΔT7、ΔT8、ΔT9、ΔT5、ΔT4、ΔT3、ΔT1以及ΔT2。等待時間資訊WIj包括接收開始時間差ΔTj、…、ΔT2。藉此，成為中繼器的各通訊終端CTj得到接收開始時刻差ΔTj。等待時間Wj從接收開始時間差ΔTj獲得。電力系統30只發生1次模擬停電的情況下，等待時間Wj是接收開始時刻差ΔTj本身。電力系統30發生複數次模擬停電的情況下，等待時間Wj是複數的接收開始時刻差ΔTj的最小值及最大值之間的時間。藉此，能夠將等待時間Wj設定在必要的最小值，能夠削減電力儲藏器121的電容。等待時間Wj也可以藉由補正接收開始時刻差ΔTj來獲得。電力系統30發生複數次模擬停電的情況下，電力系統30的模擬停電也可以1天進行一次，也可以在每次新的通訊終端追加到多重跳接式網路1使通訊路徑變更時進行電力系統30的模擬停電。成為中繼器的各通訊終端CTj開始以接收狀態等待在電力系統30發生模擬停電後經過等待時間Wj後的時間點接收停電通知BNi。例如，通訊終端CT6開始以接收狀態等待在電力系統30發生模擬停電後經過等待時間W6後的時間點接收停電通知BN10。The waiting time information WI2 includes the reception start time difference ΔT6, ΔT7, ΔT8, ΔT9, ΔT5, ΔT4, ΔT3, ΔT1, and ΔT2. The waiting time information WIj includes the reception start time difference ΔTj, ..., ΔT2. Thereby, each communication terminal CTj that becomes a repeater obtains the reception start time difference ΔTj. The waiting time Wj is obtained from the reception start time difference ΔTj. When the power system 30 has only one simulated power failure, the waiting time Wj is the reception start time difference ΔTj itself. When the power system 30 has multiple simulated power failures, the waiting time Wj is the time between the minimum value and the maximum value of the multiple reception start time difference ΔTj. Thereby, the waiting time Wj can be set to the required minimum value, and the capacitance of the power storage 121 can be reduced. The waiting time Wj can also be obtained by correcting the reception start time difference ΔTj. In the case of multiple simulated power failures in the power system 30, the simulated power failure of the power system 30 can also be performed once a day, or each time a new communication terminal is added to the multi-hop network 1 to change the communication path. The simulated power failure of the system 30. Each communication terminal CTj that becomes a repeater starts to wait in a receiving state to receive the power failure notification BNi at a time point after the waiting time Wj elapses after the simulated power failure of the power system 30 occurs. For example, the communication terminal CT6 starts to wait in the receiving state to receive the power failure notification BN10 at a time point after the waiting time W6 elapses after the simulated power failure of the power system 30 occurs.

較佳的是，集約裝置12或母局13將使通訊終端CT1-CT10具有的時刻資訊同步的時刻同步資訊發送到通訊終端CT1-CT10。例如，集約裝置12或母局13每天一次在0點將時刻同步資訊發送到通訊終端CT1-CT10。藉此，通訊終端CT1-CT10所具有的時刻資訊會同步，能夠抑制接收開始時刻差ΔT6、ΔT7、ΔT8、ΔT9、ΔT5、ΔT4、ΔT3、ΔT1以及ΔT2所包含的誤差。此時，時刻同步資訊從母局13或集約裝置12傳送到通訊終端CT1-CT10為止所需要的時間的誤差是微秒等級，通訊終端CT1-CT10所具有的時刻資訊的誤差是秒等級，因此事實上不需要考慮前者的誤差。Preferably, the centralized device 12 or the parent office 13 sends the time synchronization information that synchronizes the time information possessed by the communication terminals CT1-CT10 to the communication terminals CT1-CT10. For example, the centralized device 12 or the home office 13 sends time synchronization information to the communication terminals CT1-CT10 at 0:00 once a day. Thereby, the time information possessed by the communication terminals CT1-CT10 will be synchronized, and the errors contained in the reception start time differences ΔT6, ΔT7, ΔT8, ΔT9, ΔT5, ΔT4, ΔT3, ΔT1, and ΔT2 can be suppressed. At this time, the error in the time required for the time synchronization information to be transmitted from the parent station 13 or the centralized device 12 to the communication terminals CT1-CT10 is in the microsecond level, and the error in the time information possessed by the communication terminals CT1-CT10 is in the second level, so In fact, there is no need to consider the error of the former.

Equation (4) can be imported from the time chart shown in Figure 6.

2.9 實施型態的發明的效果 根據實施型態2的發明，與實施型態1的發明相同，電力系統30發生停電，以電力儲藏器121放電的第2電力使無線部104動作的情況下，無線通訊的通訊速度從第1通訊速度加快到第2通訊速度，能夠縮短無線通訊所需要的時間。因此，能夠削減為了使無線部104動作所需要的電力量，能夠削減電力儲藏器121的容量。2.9 Effect of implementation type invention According to the invention of the second embodiment, similar to the invention of the first embodiment, when a power outage occurs in the power system 30 and the wireless unit 104 is operated with the second power discharged from the power storage 121, the communication speed of the wireless communication changes from the first The communication speed is increased to the second communication speed, which can shorten the time required for wireless communication. Therefore, the amount of power required to operate the wireless unit 104 can be reduced, and the capacity of the power storage 121 can be reduced.

再加上，根據實施型態2的發明，電力系統30發生停電時，通訊終端CT1-CT10的通訊路經成為串珠狀的通訊路徑的狀態下，各通訊終端發送停電通知。因此，各通訊終端發送停電通知的次數僅為1次。又，2個以上的通訊終端不會同時發送停電通知。因此，能夠抑制CCA失敗，能夠以短時間發送停電通知。In addition, according to the invention of the second embodiment, when a power failure occurs in the power system 30, the communication paths of the communication terminals CT1 to CT10 become beaded communication paths, and each communication terminal sends a power failure notification. Therefore, the number of times that each communication terminal sends a power outage notification is only one. In addition, two or more communication terminals will not send power outage notifications at the same time. Therefore, CCA failure can be suppressed, and the power failure notification can be sent in a short time.

Figure 3 is a block diagram showing the communication terminal of the third embodiment. Figures 4 and 5 are flowcharts showing the control procedure of the communication terminal of the third embodiment when the power system is out of power. Fig. 6 is a flowchart showing the temporal change of the power consumption of the communication terminal according to the third embodiment.

實施型態3主要在下述的點與實施型態2不同。關於下述的點，與實施型態2中採用的架構相同的架構也會在實施型態3中採用。Implementation Type 3 is different from Implementation Type 2 mainly in the following points. Regarding the following points, the same architecture as that adopted in Implementation Type 2 will also be adopted in Implementation Type 3.

3.2 電力系統的停電時的通訊路徑 實施型態2中，電力系統30發生停電時，通訊終端CT1-CT10的全部的通訊路徑從通常的通訊路徑切換到電力系統30的停電時的通訊路徑。對此，實施型態3中，電力系統30發生停電時，通訊終端CT1-CT10的一部分的通訊路徑從通常的通訊路徑切換到電力系統30的停電時的通訊路徑。通訊終端CT1-CT10的一部分是具備只有小容量的電力儲藏器121、或者是劣化的電力儲藏器121的通訊終端。藉此，即使是變更通訊終端CT1-CT10的全部的通訊路徑困難的情況下，也能夠削減電力系統30發生停電時通訊終端CT1-CT10消費的電力量。3.2 The communication path during a power outage in the power system In the second embodiment, when a power outage occurs in the power system 30, all the communication paths of the communication terminals CT1 to CT10 are switched from the normal communication path to the communication path when the power system 30 is out of power. In contrast, in the third embodiment, when a power failure occurs in the power system 30, a part of the communication path of the communication terminals CT1 to CT10 is switched from the normal communication path to the communication path during the power failure of the power system 30. A part of the communication terminals CT1 to CT10 is a communication terminal equipped with a power storage 121 having only a small capacity or a degraded power storage 121. Thereby, even when it is difficult to change all the communication paths of the communication terminals CT1 to CT10, it is possible to reduce the amount of power consumed by the communication terminals CT1 to CT10 when a power failure occurs in the power system 30.

第15圖係顯示具備實施型態3的通訊終端之多重跳接式網路中所設置的集約裝置或母局所管理的對照表。第16圖係顯示構成具備實施型態3的通訊終端之多重跳接式網路的複數的通訊終端的電力系統停電時的通訊路徑。Figure 15 shows a comparison table managed by the centralized device or the parent office installed in the multi-hop network with the communication terminal of the implementation type 3. Fig. 16 shows the communication path of a plurality of communication terminals forming a multi-hop network with communication terminals of the third embodiment when the power system is out of power.

When a power outage occurs in the power system 30, an address 212 and a destination address 217 during a power outage will be assigned, so that each communication terminal 11x sends data to the address that has the same address as the destination address assigned to each communication terminal 11x during a power outage Communication terminal. In addition, when a power failure occurs in the power system 30, Trank 216 is paid, so that each communication terminal 11x transmits data to the communication terminal of the lower rank Trank than the Trank paid to each communication terminal 11x.

根據第15圖所示的對照表201，分別被付與終端編號「1」及「2」的通訊終端CT1及CT2，會被付與Trank「1」。又，分別被付與終端編號「3」及「5」的通訊終端CT3及CT5，會被付與Trank「2」。又，分別被付與終端編號「4」、「7」及「8」的通訊終端CT4、CT7及CT8，會被付與Trank「3」。又，分別被付與終端編號「6」、「9」及「10」的通訊終端CT6、CT9及CT10，會被付與Trank「4」。According to the comparison table 201 shown in Fig. 15, the communication terminals CT1 and CT2 assigned terminal numbers "1" and "2", respectively, will be assigned Trank "1".

The address "xx.xxx.xxx.xe" assigned to the communication terminal CT5 of "is the same. Also, the communication terminals CT6 and CT10, which are assigned terminal numbers "6" and "10", will be assigned the destination address "xx.xxx.xxx.xg" at the time of power outage, which is the same as the assigned terminal number "7".

In addition, the communication terminal CT9 assigned the terminal number "9" will be assigned the destination address "xx.xxx.xxx.xh" at the time of power outage, and it will be assigned to the communication terminal CT8 assigned the terminal number "8". The address "xx.xxx.xxx.xh" is the same.

結果，如第16圖所示，電力系統30停電時，分別被付與終端編號「6」及「10」的通訊終端CT6及CT10將資料發送到被付與終端編號「7」的通訊終端CT7。又，被付與終端編號「9」的通訊終端CT9將資料發送到被付與終端編號「8」的通訊終端CT8。又，分別被付與終端編號「4」及「8」的通訊終端CT4及CT8將資料發送到被付與終端編號「5」的通訊終端CT5。又，被付與終端編號「7」的通訊終端CT7將資料發送到被付與終端編號「3」的通訊終端CT3。又，被付與終端編號「5」的通訊終端CT5將資料發送到被付與終端編號「2」的通訊終端CT2。又，被付與終端編號「3」的通訊終端CT3將資料發送到被付與終端編號「1」的通訊終端CT1。又，分別被付與終端編號「1」及「2」的通訊終端CT1及CT2將資料發送到集約裝置12。As a result, as shown in Figure 16, when the power system 30 is out of power, the communication terminals CT6 and CT10 assigned the terminal numbers "6" and "10" respectively send the data to the communication terminal CT7 assigned the terminal number "7" . In addition, the communication terminal CT9 assigned the terminal number "9" sends the data to the communication terminal CT8 assigned the terminal number "8".

In addition, the communication terminals CT1 and CT2 assigned with terminal numbers "1" and "2", respectively, send the data to the aggregation device 12.

第17圖係顯示決定具備實施型態3的通訊終端之多重跳接式網路中的Trank的方法的流程圖。Figure 17 is a flow chart showing the method of determining the Trank in the multi-hop network with the communication terminal of the implementation type 3.

第17圖所示的步驟S131中，開始製作電力系統30停電時的通訊路徑。In step S131 shown in FIG. 17, the creation of a communication path when the power system 30 is out of power is started.

在步驟S132，判定付與到著眼的通訊終端的rank的值是否為1。判定rank的值是1的情況下，執行步驟S133。判斷rank的值不是1的情況下，執行步驟S134。In step S132, it is determined whether or not the value of the rank assigned to the communication terminal of interest is 1. If it is determined that the value of rank is 1, step S133 is executed. If it is determined that the value of rank is not 1, step S134 is executed.

在步驟S133，被付與到著眼的通訊終端的Trank的值被設定成與已經被付與到著眼的通訊終端的rank的值相同的值並儲存。In step S133, the value of Trank assigned to the communication terminal of interest is set to the same value as the value of rank assigned to the communication terminal of interest and stored.

在步驟S134，判定顯示出著眼的通訊終端所具備的電力儲藏器121的容量之預備電源容量是否不滿閾值。預備電源容量不滿閾值的情況下，執行步驟S135。預備電源容量在閾值以上的情況下，執行步驟S133，被付與到著眼的通訊終端的Trank的值被設定成與rank的值相同的值並儲存。在步驟S135，被付與到著眼的通訊終端的Trank的值被設定成比已經被付與到著眼的通訊終端的rank的值更低位的值並儲存。例如，已經被付與到著眼的通訊終端的rank的值是3的情況下，被付與到著眼的通訊終端的Trank的值被設定為4並儲存。藉此，已經被付與到著眼的通訊終端的rank的值是1的情況下，不管預備電源容量是否不滿閾值，Trank的值被設定為1。藉此，能夠抑制被付與rank「1」的通訊終端變得無法發送資料到集約裝置12。又，已經被付與到著眼的通訊終端的rank的值是2或者是比2更低位，且預備電源容量在閾值以上的情況下，Trank的值變被迫與rank的值一致。又，已經被付與到著眼的通訊終端的rank的值是2或者是比2更低位，且預備電源容量不滿閾值的情況下，Trank的值會被設定到比rank的值更低位的值。In step S134, it is determined whether or not the reserve power supply capacity indicating the capacity of the power storage 121 included in the communication terminal of interest is less than the threshold value. When the reserve power supply capacity is less than the threshold value, step S135 is executed. When the reserve power capacity is greater than or equal to the threshold value, step S133 is executed, and the value of Trank assigned to the communication terminal of interest is set to the same value as the value of rank and stored. In step S135, the value of Trank assigned to the communication terminal of interest is set to a lower value than the value of rank assigned to the communication terminal of interest and stored. For example, when the value of rank assigned to the communication terminal of interest is 3, the value of rank assigned to the communication terminal of interest is set to 4 and stored. With this, when the value of rank that has been assigned to the communication terminal of interest is 1, the value of Trank is set to 1 regardless of whether the reserve power capacity is less than the threshold value. As a result, it is possible to prevent the communication terminal assigned the rank "1" from becoming unable to send data to the aggregation device 12. In addition, when the rank value of the communication terminal that has been paid attention is 2 or lower than 2, and the reserve power capacity is above the threshold, the value of Trank is forced to match the value of rank. In addition, if the rank value of the communication terminal that has been paid attention is 2 or lower than 2, and the reserve power capacity is less than the threshold value, the value of Trank will be set to a value lower than the value of rank.

各通訊終端11x將資料發送到被付與的Trank比被付與到各通訊終端11x的Trank更高位的通訊終端。因此，例如，被付與終端編號「4」的通訊終端CT4被付與了比rank「2」及比其低位的Trank「3」的情況下，通訊終端CT4的周圍的通訊終端因為具有與被付與到通訊終端CT4的Trank「3」相同的Trank或高位的Trank，在檢測出電力系統30的停電的情況下，就變得不會中繼通訊終端CT4所發送的資料。藉此，電力系統30發生停電期間所發送的停電通知的發送次數1次就足夠了。藉此，能夠削減具有小的預備電源容量的通訊終端在電力系統30發生停電的期間消耗的電力量。Each communication terminal 11x transmits the data to a communication terminal with a higher rank than the Trank assigned to each communication terminal 11x. Therefore, for example, if the communication terminal CT4 assigned the terminal number "4" is assigned the rank "2" and the lower rank "3", the communication terminals around the communication terminal CT4 have the The same Trank or higher Trank as the Trank "3" attached to the communication terminal CT4 will not relay the data sent by the communication terminal CT4 when a power failure of the power system 30 is detected. In this way, the number of times of transmission of the power failure notification transmitted during the occurrence of a power failure in the power system 30 is sufficient. Thereby, it is possible to reduce the amount of electric power consumed by a communication terminal having a small reserve power source capacity during a power failure of the electric power system 30.

根據實施型態3，與實施型態1相同，電力系統30發生停電，以電力儲藏器121放電的第2電力使無線部104動作的情況下，無線通訊的通訊速度從第1通訊速度加快到第2通訊速度，能夠縮短無線通訊所需要的時間。因此，能夠削減為了使無線部104動作所需要的電力量，能夠削減電力儲藏器121的容量。According to Embodiment 3, similar to Embodiment 1, when a power failure occurs in the power system 30 and the wireless unit 104 is activated with the second power discharged from the power storage 121, the communication speed of wireless communication is increased from the first communication speed to The second communication speed can shorten the time required for wireless communication. Therefore, the amount of power required to operate the wireless unit 104 can be reduced, and the capacity of the power storage 121 can be reduced.

再加上，根據實施型態3的發明，取代定義通常時的通訊路徑之rank213所使用的，定義電力系統30停電時的通訊路徑之複數的Trank216被設定。因此，能夠一邊按照多重跳接式網路1的既存的多重跳接式網路規格，一邊削減通訊終端CT1-CT10的消耗電力量，能夠削減電力儲藏器121的容量。In addition, according to the invention of the third embodiment, instead of the rank 213 used to define the normal communication path, the plural Trank 216 that defines the communication path when the power system 30 is out of power is set. Therefore, the power consumption of the communication terminals CT1-CT10 can be reduced while complying with the existing multi-hop network specifications of the multi-hop network 1, and the capacity of the power storage 121 can be reduced.

另外，本發明在發明的範圍內，能夠將各實施型態自由組合，或將各實施型態適當地變形、省略。In addition, within the scope of the present invention, various embodiments can be freely combined, or various embodiments can be appropriately modified or omitted.
