Description

一般來說，現有的交通號誌燈與主控箱之間係以電線連接，也就是說，若一個主控箱對應控制八個交通號誌燈時，主控箱則需以八條電線分別連接各交通號誌燈。 Generally speaking, the existing traffic signal lights and the main control box are connected by wires. That is to say, if one main control box corresponds to control eight traffic signal lights, the main control box needs to use eight wires respectively. Connect each traffic signal light.
承上述之連接方式，遇到路口之燈號需求較多時，將面臨電線數量多且配置複雜的情況，進而於埋設電線或維修交通號誌燈時，導致施工期冗長且施工成本增加；而礙於主控箱容置空間有限，進而限制了對應控制的交通號誌燈數量，故交通號誌燈數量多時，將需要額外增設配線箱；且由於電線配置數量多，故容易產生電線短路的情況，而造成燈號混亂的情況發生；另一方面，更由於電線配置繁雜，是以當故障發生時，將難以尋找故障發生位置。 With the above-mentioned connection methods, when there is a large demand for lights at intersections, there will be a large number of wires and complex configurations. Further, when laying wires or repairing traffic lights, the construction period will be lengthy and the construction cost will increase; and Due to the limited accommodating space of the main control box, the number of traffic signal lights to be controlled is limited. Therefore, when the number of traffic signal lights is large, an additional wiring box will be needed; and because of the large number of wires, it is easy to cause short circuits. When a fault occurs, it will be difficult to find the location of the fault because of the complicated wiring configuration.

請參閱第1圖，其係為本發明之交通號誌控制系統之第一方塊圖。如圖所示，本發明之交通號誌控制系統100包含了控制主機110及交通號誌組120。 Please refer to Figure 1, which is the first block diagram of the traffic sign control system of the present invention. As shown in the figure, the traffic signal control system 100 of the present invention includes a control host 110 and a traffic signal group 120.
續言之，上述之控制主機110產生控制訊號組，控制訊號組由複數個控制訊號組成，各控制訊號具有不同的控制指令及其所欲傳遞的對象(下述所提到之控制子機)。 In addition, the above-mentioned control host 110 generates a control signal group, which is composed of a plurality of control signals, and each control signal has a different control command and the object to be transmitted (the control slave mentioned below) .
交通號誌組120由複數個交通號誌模組121串接連結而成，且各交通號誌模組121包含控制子機122及燈號桿組123，控制子機122連接燈號桿組 123，控制主機110以訊號線連接交通號誌組120之一端的交通號誌模組121，並以另一訊號線連接交通號誌組120之另一端的另一交通號誌模組121；也就是說，控制主機110用兩條訊號線分別連結交通號誌組120之兩端的交通號誌模組121；另一方面，也可以理解為控制主機110以兩條訊號線連接複數個交通號誌模組121中的其中兩個；更進一步地，訊號線之數量並不限定為兩條，是以控制主機110可以複數條訊號線分別連結複數個交通號誌模組121中對應訊號線數量的複數個交通號誌模組121；然，上述僅為舉例，並不以此為限。 The traffic signal group 120 is composed of a plurality of traffic signal modules 121 connected in series, and each traffic signal module 121 includes a control slave 122 and a light pole group 123, and the control slave 122 is connected to the light pole group 123. The control host 110 connects the traffic signal module 121 at one end of the traffic signal group 120 with a signal line, and connects another traffic signal module 121 at the other end of the traffic signal group 120 with another signal line; also That is, the control host 110 uses two signal lines to connect the traffic signal modules 121 at both ends of the traffic signal group 120; on the other hand, it can also be understood that the control host 110 connects a plurality of traffic signals with two signal lines. Two of the modules 121; further, the number of signal lines is not limited to two, so the control host 110 can connect multiple signal lines to the corresponding number of signal lines in the traffic signal module 121 A plurality of traffic signal modules 121; however, the above is only an example, and is not limited to this.
而，上述所提到之控制主機110與交通號誌組120之連結方式之用意在於，由於各交通號誌模組121相互串接，若以一條訊號線連結其中一端的交通號誌模組121並傳送控制訊號組，然後控制訊號組再一一傳送至所串接之下一個交通號誌模組121時，若訊號線發生異常，或其中兩個交通號誌模組121之間串接發生異常時，會導致後續的交通號誌模組121皆無法接收到控制訊號組；是以，若以兩條訊號線分別連結兩端的交通號誌模組121時，只要不是兩條訊號線都發生異常，便可藉由至少一條訊號線傳送控制訊號組到大部分的交通號誌模組121。且，經由此連接方式，可簡易的得知是哪一條訊號線、哪一個交通號誌模組121或是那些交通號誌模組121之間的連結發生異常，而減少找尋故障原因的時間且提升故障排除的效率。 However, the above-mentioned connection method of the control host 110 and the traffic signal group 120 is intended to be that since the traffic signal modules 121 are connected in series, if one signal line is used to connect the traffic signal module 121 at one end And send the control signal group, and then send the control signal group one by one to the next traffic signal module 121 connected in series, if the signal line is abnormal, or two of the traffic signal modules 121 are connected in series When abnormal, the subsequent traffic signal modules 121 will not be able to receive the control signal group; therefore, if two signal lines are connected to the traffic signal modules 121 at both ends, as long as the two signal lines do not occur If it is abnormal, the control signal group can be transmitted to most of the traffic signal modules 121 through at least one signal line. Moreover, through this connection method, it is easy to know which signal line, which traffic signal module 121 or the connection between those traffic signal modules 121 is abnormal, which reduces the time to find the cause of the fault and Improve the efficiency of troubleshooting.
承上述，控制訊號組由二訊號線傳送至各交通號誌模組121，各控制子機122對控制訊號組進行運算而產生對應之控制指令及回報訊號，並依據控制指令驅動燈號桿組123顯示對應之燈號，及傳送回報訊號至控制主機110，控制主機110依據複數個回報訊號產生控制訊號組。由於，控制訊號組中具有複數個控制訊號及其欲傳遞的控制子機122，也就是對不同控制子機122可能會有 不同的控制指令，因此每個控制子機122都需要對控制指令組做運算，並從中得到對應本身的控制訊號及據以運算出控制指令；另一方面，控制主機110需要掌握連結控制了多少控制子機122，因此，各控制子機122再接收到控制訊號組時也會對應產生回報訊號，回報訊號中便產生了控制子機122的相關資料(如訊號、位置、狀態或其組合)，進而當控制主機110接收到各控制子機122所回傳的回報訊號時，便可進一步了解控制了哪些控制子機122，進而可對應的產生控制訊號組，以進行下一輪的交通號誌控制。 In accordance with the above, the control signal group is transmitted to each traffic signal module 121 by two signal lines, and each control sub-machine 122 performs operations on the control signal group to generate corresponding control commands and report signals, and drives the light pole group according to the control commands 123 displays the corresponding light signal, and sends a report signal to the control host 110, and the control host 110 generates a control signal group according to a plurality of report signals. Because there are a plurality of control signals and the control slaves 122 to be transmitted in the control signal group, that is, there may be different control slaves 122 Different control commands, so each control slave 122 needs to perform calculations on the control command group, and obtain the corresponding control signal from it and calculate the control command based on it; on the other hand, the control host 110 needs to know how much the connection controls Control slave 122. Therefore, when each control slave 122 receives the control signal group, it will also generate a corresponding report signal, and the relevant data of the control slave 122 (such as signal, position, state or combination thereof) will be generated in the report signal. , And then when the control host 110 receives the return signal from each control sub-machine 122, it can further understand which control sub-machines 122 are controlled, and then can correspondingly generate a control signal group for the next round of traffic signals control.
而，控制主機110可判斷複數個回報訊號之數量是否等於複數個控制子機122之數量，當複數個回報訊號之數量不等於複數個控制子機122之數量時，對應產生故障訊號。當複數個回報訊號之數量小於複數個控制子機122之數量時，便表示有控制子機122未產生回報訊號，進而表示該控制子機122可能發生異常，故需要產生故障訊號並通報給控制中心，以進行後續處理；另一方面，若複數個回報訊號之數量大於複數個控制子機122之數量時，便表示可能有額外的控制子機122加入，此時產生故障訊號並通報給控制中心，以請控制中心確認是否有新的控制子機122加入或是有誤觸、誤接等情況。然，上數僅為舉例，並不以此為限。 However, the control host 110 can determine whether the number of the plurality of report signals is equal to the number of the plurality of control slave machines 122, and when the number of the plurality of report signals is not equal to the number of the plurality of control slave machines 122, a fault signal is correspondingly generated. When the number of the plurality of report signals is less than the number of the plurality of control slave units 122, it means that the control slave unit 122 has not generated the report signal, which in turn means that the control slave unit 122 may be abnormal, so it is necessary to generate a fault signal and report to the control On the other hand, if the number of report signals is greater than the number of control slaves 122, it means that additional control slaves 122 may be added. At this time, a fault signal is generated and notified to the control Center, so that the control center can confirm whether there is a new control sub-machine 122 added or if there is a mistouch, misconnection, etc. Of course, the above numbers are only examples and not a limitation.
請參閱第2圖，其係為本發明之交通號誌控制系統之第二方塊圖。如圖所示，上述之控制子機122可具有異常檢測單元124，異常檢測單元124用以檢測燈號桿組123且對應燈號桿組123之異常狀態產生異常訊號，即檢測燈號是否可正常運作，其傳送異常訊號至控制主機110，控制主機110對應異常訊號產生故障訊號，故障訊號可通報控制中心，以利後續故障排除處理。 Please refer to Figure 2, which is the second block diagram of the traffic sign control system of the present invention. As shown in the figure, the aforementioned control slave 122 may have an abnormality detection unit 124, which is used to detect the light pole group 123 and generate an abnormal signal corresponding to the abnormal state of the light pole group 123, that is, whether the light signal can be detected In normal operation, it transmits an abnormal signal to the control host 110, and the control host 110 generates a fault signal corresponding to the abnormal signal, and the fault signal can be reported to the control center for subsequent troubleshooting.
值得一提的是，控制主機110與各控制子機122之間的訊號傳送接收採用can bus通訊模組，所傳送的控制訊號組中包含控制指令(如燈號命令)，而所傳送的回傳訊號或異常訊號中包含了子機狀態回傳及綠燈衝突表傳送等，其指令格式如下： It is worth mentioning that the signal transmission and reception between the control host 110 and each control slave 122 adopts the can bus communication module, and the transmitted control signal group contains control commands (such as light command), and the transmitted return The transmission signal or abnormal signal includes slave status return and green light conflict table transmission, etc. The command format is as follows:
1.燈號命令：Cmd+signal(6Bytes)+CheckSum 1. Light command: Cmd+signal(6Bytes)+CheckSum
2.子機狀態回傳：Cmd+Status+DeviceId(2Bytes)+ReportId(2Bytes)+CheckSum 2. Sub-machine status return: Cmd+Status+DeviceId(2Bytes)+ReportId(2Bytes)+CheckSum
3.綠燈衝突表傳送：將綠燈衝突表分成23筆資料傳送，並在最後一筆資料中加入CheckSum以筆對資料之完整性。 3. Green light conflict table transmission: divide the green light conflict table into 23 data transmissions, and add CheckSum to the last data to check the integrity of the data.
(1).Cmd+ConflictData(7Bytes),...,(23).Cmd+ConflictData(6Bytes)+CheckSum (1).Cmd+ConflictData(7Bytes),...,(23).Cmd+ConflictData(6Bytes)+CheckSum
補充定義說明如下：Cmd：指令碼，各種命令皆不同，如燈號命令為A0h。 The supplementary definition description is as follows: Cmd: instruction code, various commands are different, for example, the light command is A0h.
signal：燈號資料，共6bytes帶表各子機上燈號輸出單元之亮燈狀態。 signal: Light signal data, a total of 6 bytes with the light status of the light signal output unit on each slave machine.
CheckSum：檢查碼，用以跟同筆資料檢核用，以確保資料正確性。 CheckSum: Check code, used to check the same data to ensure the correctness of the data.
Status：子機狀態，共8bits各帶表子機現行的各種狀態。 Status: The status of the slave, a total of 8 bits of the current status of each slave with a meter.
DeviceId：子機編號，主機用以判斷為哪台子機回報的資料。 DeviceId: The slave number, the data used by the master to determine which slave is reporting.
ReportId：回報編號，主機用以重設子機編號避免子機編號重複使用。 ReportId: Report number, the host is used to reset the slave number to avoid repeated use of the slave number.
ConflictData：綠燈衝突表資料。 ConflictData: Green light conflict table data.
而，控制子機122可產生子控制訊號且依據子控制訊號驅動燈號桿組123顯示對應之燈號。即，控制子機122可獨立控制其連結之燈號桿組123， 惟仍以控制主機110所傳送的控制指令為優先，因此若控制主機110有給控制子機122控制指令且控制子機122也取得該控制指令時，就算控制子機122產生子控制訊號，也要以控制指令為主而依據控制指令驅動燈號桿組123。 However, the control slave 122 can generate a sub-control signal and drive the light pole group 123 to display the corresponding light signal according to the sub-control signal. That is, the control slave 122 can independently control the connected light pole group 123, However, the control command sent by the control host 110 is still given priority. Therefore, if the control host 110 sends a control command to the control slave 122 and the control slave 122 also obtains the control command, even if the control slave 122 generates a sub-control signal, The light pole group 123 is driven based on the control instruction and according to the control instruction.
續言之，若控制子機122於預設時間未接收到控制訊號組時，控制子機122產生子控制訊號。該情況往往發生於交通號誌控制系統100故障時，導致控制主機110的控制訊號組無法傳送至交通號誌模組121，惟怕交通號誌模組121因未接收到控制指令而無法正常顯示燈號而產生燈號衝突等情況，是以控制子機122可內建防故障保護機制，即如上述所說，若預設時間內未接收到控制訊號組時，則須依據防故障保護機制產生子控制訊號，進而暫時控制燈號改變(如停止顯示燈號或閃黃燈等)，以避免造成重大交通影響；然，上述僅為舉例，並不以此為限。 In addition, if the control sub-machine 122 does not receive the control signal group within the preset time, the control sub-machine 122 generates a sub-control signal. This situation often occurs when the traffic signal control system 100 fails, and the control signal group of the control host 110 cannot be transmitted to the traffic signal module 121, but the traffic signal module 121 is afraid that the traffic signal module 121 cannot be displayed normally because it has not received the control command. Light signal conflicts and other situations are caused by the control slave 122 can have a built-in anti-failure protection mechanism, that is, as mentioned above, if the control signal group is not received within the preset time, the anti-failure protection mechanism must be used Generate a sub-control signal, and then temporarily control the change of the light signal (such as stopping the display of the light signal or flashing amber light, etc.) to avoid major traffic impacts; however, the above are only examples and not limited to this.
進一步地，1.當通訊中斷後，控制子機0.8秒(及上述預設時間)未收到控制主機的控制訊號組時，即關閉該控制子機所有顯示之燈號，以防單一控制子機之燈號與其他控制子機不同步而發生綠燈衝突。 Further, 1. When the communication is interrupted, when the control slave does not receive the control signal group from the control host for 0.8 seconds (and the above-mentioned preset time), all the lights displayed on the control slave are turned off to prevent a single control slave The light signal of the machine is out of sync with other control slave machines and a green light conflict occurs.
2.控制主機與各控制子機的訊號線(通訊線)、電源線及管路連接線皆為並聯在一起，且連接成一環狀，當有外在因素使某線路節點斷路時，控制主機即可測得線路異常(此時燈號及訊號通訊還可正常運作)，在系統還可正常運作時可即時通知相關做緊急處理。 2. The signal lines (communication lines), power lines and pipeline connecting lines of the control host and each control slave are all connected in parallel and connected in a ring. When an external factor causes a circuit node to be disconnected, the control host The abnormality of the line can be detected (the light and signal communication can still operate normally at this time), and when the system can still operate normally, it can be notified immediately for emergency treatment.
3.當控制子機所亮燈號發生綠燈衝突(例如北向綠燈及東向綠燈同時亮起)，此時即會啟動綠燈衝突的保護機制，此機制有兩種模式可選擇： 3. When a green light conflict occurs in the light signal of the control slave (for example, the northbound green light and the eastbound green light are on at the same time), the protection mechanism of green light conflict will be activated at this time. There are two modes for this mechanism to choose:
(1).該綠燈衝突的控制子機將全部燈號完全關閉，以防錯誤燈號造成用路人判斷造成車禍。 (1). The control sub-machine of the green light conflict will completely turn off all the lights to prevent the wrong light from causing a car accident based on the judgment of passers-by.
(2).由控制子機回報控制主機，控制主機即會控制全部控制子機切換為閃光燈號，此模式與傳統號誌控制器相同。 (2). The control slave will report back to the control host, and the control host will control all the control slaves to switch to flash lights. This mode is the same as the traditional signal controller.
(3).綠燈衝突的對應燈號亦可經由控制主機的操作介面更改綠燈衝突表，以使用於特殊點燈的路口。 (3). The corresponding light number of the green light conflict can also be changed to the green light conflict table through the operation interface of the control host, so as to be used at the intersection of special lighting.
(4).全部控制子機的綠燈衝突判斷皆會以全部方向實際點燈的燈號做為判斷，不會因單一控制子機只有接特定方向而沒有偵測出與其他方向有綠燈衝突的狀況(例如單一控制子機只使用北向燈號，程式亦會將東南西方向燈號與本身的北向燈號比對綠燈衝突)。然，上述僅為舉例，並不以此為限。 (4). The green light conflict judgments of all control slaves will be judged based on the actual lights of all directions. There will be no green light conflicts with other directions because a single control slave only connects to a specific direction. Status (for example, when a single control handset only uses the northbound light, the program will also compare the southeast-west direction light with its own northbound light to conflict with the green light). Of course, the above is only an example, and it is not limited thereto.
儘管前述在說明本發明之交通號誌控制系統的過程中，亦已同時說明本發明之交通號誌控制方法的概念，但為求清楚起見，以下另繪示流程圖詳細說明。 Although the foregoing description of the traffic sign control system of the present invention has also explained the concept of the traffic sign control method of the present invention, for the sake of clarity, a flowchart is shown below for detailed description.
