Description
本新型係有關於一種路***通號誌控制系統的設計，尤指一種網路形態之分離式路***通號誌控制器運用網路通訊技術所構成的高可用度系統。 This new type relates to the design of a traffic control system for intersections, especially a high-availability system composed of network communication technology using a network communication technology.
傳統的路***通號誌控制器多採集中式架構，一大型號誌控制器中之控制模組執行燈號控制運算邏輯，並電性連結每一號誌燈之燈號驅動模組，每組燈號驅動單元與外線連接，外線再以一燈一線方式連接各號誌燈桿的號誌燈。傳統號誌控制器中的號誌燈驅動模組需集中配置每一號誌燈號的連接線，再以放射狀佈線方式連接各路口的號誌燈，因此控制箱內號誌燈驅動線路密集又複雜，容易造成驅動電路周遭溫度升高，吸引壁虎、昆蟲依附於密集的線路上造成線路短路，而影響交通號誌的正常運作。此外，密集的號誌燈驅動線路亦需較大體積的控制箱體以容納端子盤或大電力輸出，導致號誌控制箱體龐大，容易成為路口轉角行人步行的阻礙，也影響市容景觀。在號誌控制系統佈線方面，因應管線地下化趨勢，傳統集中式路***通號誌控制器以自身設備為中心，以一燈一線之放射狀佈線方式連結各個路口燈號，在建置施工、未來維修或需要新增號誌燈時(例 如：增加右轉燈組)，需要重挖路面距離長、施工成本高，在施工期間也嚴重影響車輛通行。 The traditional intersection traffic signal controller multi-acquisition Chinese architecture, the control module in a large model controller performs the signal control logic, and electrically connects the signal drive module of each number of lights, each set of lights The drive unit is connected to the external line, and the external line is connected to the number of the respective light poles in a light and a line manner. In the traditional semaphore controller, the locomotive lamp driver module needs to centrally configure the connection line of each horn signal, and then connect the horn lights of each intersection with radial wiring, so the signal light in the control box is densely driven. It is also complicated, which is easy to cause the temperature around the drive circuit to rise, attracting geckos and insects to adhere to dense lines, causing short circuit, which affects the normal operation of traffic signs. In addition, the dense signal driving circuit also needs a large-volume control box to accommodate the terminal block or large power output, resulting in a large control box, which is easy to become a barrier to pedestrian walking at the corner of the intersection, and also affects the cityscape. In terms of the wiring of the control system, in response to the trend of underground pipelines, the traditional centralized traffic signal controllers are connected to each intersection by means of their own equipment, and the construction of the roads. When repairing or when you need to add a new light (example) For example, if you increase the right turn light group, you need to re-dig the road surface for a long distance and the construction cost is high. It also seriously affects the traffic during the construction period.
改良的分離式號誌控制器是將傳統號誌控制器集中式架構改成分離式的網路型架構，以改善一般道路交通號誌的電力線拉線多又長及熱度造成系統穩定度問題，如中華民國專利公報公告編號120810號專利[分散式交通號誌控制器]提出將點燈控制電路由誌控制器中分離出來，並分散安裝於各燈桿或是附近的地方，以達減少電力線引拉長度及防止密集點燈控制電路運作產生熱度影響控制單元之正常運作，此架構之控制單元與點燈控制電路間直接以通訊線連接，控制單元以放射狀佈線型態連接各路口的點燈控制電路，雖可減少佈線，在路口安裝的燈號較多時，佈線仍隨之增多而較複雜。 The improved split-type controller is to change the traditional architecture of the traditional controller to a separate network-type architecture to improve the problem of system power stability caused by the long and long power line of the general road traffic sign. For example, the Republic of China Patent Gazette No. 120810 [Distributed Traffic Signal Controller] proposes to separate the lighting control circuit from the Zhi controller and distribute it to each pole or nearby to reduce the power line. Pulling length and preventing the operation of the dense lighting control circuit to generate heat affect the normal operation of the control unit. The control unit of the architecture and the lighting control circuit are directly connected by a communication line, and the control unit connects the points of each intersection in a radial wiring pattern. The lamp control circuit can reduce wiring, and when the number of lights installed at the intersection is large, the wiring is still increased and complicated.
另一中華民國專利公報公告編號199222號專利[多功能號誌控制系統]提出一分離式架構，將號誌控制系統設計為一微電腦主機電性連結一組以上的分機，每一號誌燈處設一分機以控制號誌燈的工作狀態，以達到電腦監控，減少故障及配線簡單的目的。此架構的特點是由微電腦主機為起始點以通訊線路串接各路口分機，將微電腦主與各路口分機的通訊線路串接起來，其優點是在路口安裝的號誌桿較多或擴充時，微電腦主機與分機間的佈線不會隨之增多，使佈線工程及線路維護上更簡單，此為串接型態之路口分離式交通號誌控制系統的架構。 Another Republic of China Patent Gazette No. 199222 [Multi-Functional Control System] proposes a separate architecture, which is designed to be a microcomputer host electrically connected to a group of more than one extension, each number of lights Set an extension to control the working status of the horn light to achieve computer monitoring, reducing the problem of faults and wiring. The characteristic of this architecture is that the microcomputer host is used as the starting point to connect the intersections of the intersections with the communication lines, and the communication lines of the microcomputer main and the extensions of the intersections are connected in series. The advantage is that when the number of the poles installed at the intersection is more or expanded, The wiring between the microcomputer mainframe and the extension will not increase, which makes the wiring engineering and line maintenance simpler. This is the architecture of the serialized traffic sign control system of the serial type.
稍後另一中華民國專利公報公告編號190230號專利[網路式交通號誌控制裝置]提出一種以網路式控制交通號誌的裝置，亦採分離式架構，該專利係運用電力線的線傳載波調變/解調通信技術，將主控制器及各 路口的號誌燈組控制器直接並接在一對電力傳輸線上，路口號誌燈組控制器再控制該路口的每組號誌燈，主控制裝置與各路口的號誌燈組控制器藉由電力線做網路通信控制，並將該電力傳輸線對採用環狀迴圈配置之方式組成，藉由環狀配線方式，即使因道路施工挖斷部分線路亦可維持線路正常運作。 Later, another Republic of China Patent Gazette No. 190230 [Network Traffic Sign Control Device] proposes a device for controlling traffic signs by network, and also adopts a separate architecture, which uses line transmission of power lines. Carrier modulation/demodulation communication technology, the main controller and each The intersection of the number of the light group controller directly connected to a pair of power transmission lines, the intersection of the number of lights controller to control each group of the number of lights, the main control device and the intersection of the number of lights controller The power line is controlled by the power line, and the power transmission line is formed by adopting an annular loop configuration. By means of the ring wiring, even if some lines are cut off due to road construction, the line can be normally operated.
習知串接型態之網路型路口分離式交通號誌控制系統一般採用網路架構取代傳統號誌控制系統的集中式架構。分離式號誌控制系統由一主控制器與一組以上的燈號控制器連結其控制的號誌燈所構成，主控制器透過一通訊線電性串接各個路口的燈號控制器，如第1圖所示。各燈號控制器再電性連結其控制的號誌燈，在該通訊線上傳送控制或狀態訊息，主控制器與燈號控制器運用網路通訊及編碼/解碼的特性可以確定傳輸訊息的起始與目的設備位址及訊息內容，大幅減少傳統一燈一線的放射狀佈線方式所需的龐雜佈線工程。燈號控制器一般設置於其控制之號誌燈燈桿上或在該燈桿附近位置，以減少佈線成本。 The network type intersection-separated traffic control system of the conventional serial type generally adopts a network architecture to replace the centralized architecture of the traditional sign control system. The split type control system is composed of a main controller and a group of lights controllers connected to the control number of the lights, and the main controller electrically connects the signal controllers of the intersections through a communication line, such as Figure 1 shows. Each light controller is electrically connected to the control light of the control, and transmits a control or status message on the communication line. The main controller and the light controller use the characteristics of network communication and encoding/decoding to determine the transmission of the message. The starting and destination device addresses and message content greatly reduce the complex wiring required for the traditional one-line radial wiring method. The signal controller is generally placed on or near the lamp stem of its control to reduce wiring costs.
當分離式號誌控制器的主控制器或是任一路口的燈號控制器發生故障，或是主控制器與燈號控制器間的通訊線或其他原因造成整體分離式號誌控制器無法正常運作時，主控制器或燈號控制器通常會以系統異常的控制邏輯控制燈號亮滅狀態，以避免造成燈號顯示錯誤或部分燈號無法顯示的問題，此時，路口號誌燈是在無法正常工作狀態下，容易導致路口行車與行人發生交通事故。 When the main controller of the separate type controller or the signal controller of any intersection fails, or the communication line between the main controller and the signal controller or other reasons, the overall separate type controller cannot be In normal operation, the main controller or the signal controller usually controls the light-on status with the abnormal control logic of the system to avoid the problem that the lamp number is displayed incorrectly or some of the lights cannot be displayed. At this time, the intersection number lamp In the state of being unable to work normally, it is easy to cause traffic accidents at intersections and pedestrians.
為避免發生這種情形，本創作提出主控制器或燈號控制器具有備援設備，及在控制器設備的軟體包含系統備援處理的控制邏輯，以便 在部分控制器硬體發生故障時，整體的分離式的號誌控制系統仍可保持正常運作，也就是本創作所提出的高可用度系統架構。 In order to avoid this situation, the author proposes that the main controller or the signal controller has backup equipment, and the software of the controller device includes control logic for system backup processing, so that In the event of a partial controller hardware failure, the overall discrete control system remains operational, which is the high availability system architecture proposed by this creation.

本創作之系統架構及連線示意圖如第2圖所示。本創作具多組主控制器且可相互備援，作用中的主控制器與待命的其他備援主控制器間每隔一時間間隔會互傳控制器設備本身運作狀態訊息給對方，其作用如同設備本身自我心跳(Heart Beat)狀態通報，以確認彼此之運作狀態是否正常，當最高優先權之待命中備援主控制器無法收到先前作用中的主控制器的設備運作狀態正常訊息時，就與各路口的燈號控制器通訊確認其與原作用中主控制器間亦無法協同正常執行號誌控制後，即接替原作用中主控制器執行與燈號控制器 的通訊以完成號誌燈控制作業。例如，當備援主控制器無法收到作用中的主控制器的設備運作狀態正常訊息時，就傳送[詢問通訊狀態訊息]訊息給各路口的燈號控制器，當各路口的燈號控制器回應[號誌控制通訊中斷]時，備援主控制器可確認原先作用中的主控制器與其他控制器已無法通訊，便發送出[取得主控權訊息]訊息給所有控制器，待其他路口的燈號控制器均回應[已確認]且備援主控制器都收到後，自始起就備援主控制器間就切換為作用中的主控制器，並接替原先之主控制器執行與燈號控制器的通訊，完成號誌燈控制作業。 The system architecture and connection diagram of this creation are shown in Figure 2. The creation has multiple sets of main controllers and can be mutually redundant. The active main controller and the other standby main controllers at standby will mutually transmit the operation status information of the controller device to the other party at intervals. Like the device's own Heart Beat status notification, to confirm that each other's operating status is normal, when the highest priority standby primary controller fails to receive the previous active primary device's device operational status normal message Then, it communicates with the signal controller of each intersection to confirm that it cannot cooperate with the original controller in the original operation, and then the master controller performs the operation and the signal controller. The communication is completed to complete the operation of the number of lights. For example, when the backup main controller cannot receive the normal operation status of the device of the active main controller, it sends a [Inquiry Communication Status Message] message to the signal controller of each intersection, when the signal of each intersection is controlled. When the device responds to [Signal Control Communication Interrupt], the backup main controller can confirm that the original active controller and other controllers are unable to communicate, and then send out the [Get Master Control Message] message to all controllers. After the signal controllers of other intersections respond to [confirmed] and the backup main controllers are received, the backup main controller is switched to the active main controller from the beginning, and takes over the original main control. The device performs communication with the lamp controller to complete the control of the lamp.
本創作之另一種作用中的主控制器與待命的備援主控制器間自動切換備援運作方式是運用通訊線的訊息廣播特性，在通訊線上的控制器可以收到所有在通訊線上傳輸的訊息，備援主控制器由通訊線收到作用中的主控制器送出的控制訊息及燈號控制器的回應訊息，並檢查控制訊息是否依時制計畫正常送出及送收訊息內容判斷作用中的主控制器是否正常運作，當判斷或以通訊訊息確認原先作用中的主控制器無法正常運作後，自始起備援主控制器就取得主控權並切換為作用中的主控制器，接替原先作用中的主控制器執行與燈號控制器的通訊，完成號誌燈控制作業。 In another function of this creation, the automatic switching between the main controller and the standby backup main controller is to use the message broadcasting characteristic of the communication line, and the controller on the communication line can receive all the transmissions on the communication line. The message, the backup main controller receives the control message sent by the active main controller and the response message of the light controller from the communication line, and checks whether the control message is in accordance with the schedule of the normal delivery and the content of the received message. Whether the main controller is operating normally. When it is judged or confirmed by the communication message that the original active controller cannot operate normally, the backup main controller obtains the master control and switches to the active main controller from the beginning. Take over the original active controller to perform communication with the signal controller to complete the control of the lamp.
本創作之網路形態之分離式路***通號誌控制系統，具多組主控制器且可相互備援，其中之主控制器與備援主控制器的系統運作參數具保持一致性的控制機制，以確保二者有相同的號誌控制邏輯；系統運作參數包括控制策略參數、日期時 間、時相排列、步階參數、時制計畫、時段型態、周內日、特殊日、連鎖控制、觸動控制、調撥車道、系統參數、通訊參數、號誌控制參數等。主控制器與備援主控制器的系統運作參數保持一致性係透過系統運作參數同步作業達成，其程序為作用中或人工選定之主控制器將其記憶體中儲存的系統運作參數內容讀出，透過通訊線傳送到待命中的備援主控制器或人工選定之其他主控制器，備援主控制器或人工選定之其他主控制器再將收到的系統運作參數內容儲存到其記憶體中，以便作為系統運作參用依據。 The separate intersection traffic signal control system of the network form of the creation has multiple sets of main controllers and can be mutually redundant, wherein the control parameters of the system operation parameters of the main controller and the backup main controller are consistent. To ensure that both have the same gram control logic; system operating parameters include control strategy parameters, datetime Interphase, time phase arrangement, step parameters, time plan, time period type, weekday, special day, chain control, touch control, dialing lane, system parameters, communication parameters, number control parameters, etc. The consistency of the system operating parameters of the main controller and the backup main controller is achieved through the synchronization of the operating parameters of the system. The program reads the contents of the system operating parameters stored in the memory of the active or manually selected main controller. , through the communication line to the standby primary controller or other manually selected main controller, the backup primary controller or other manually selected other host controller to store the received system operating parameter content into its memory In order to serve as a basis for system operation.
系統運作參數同步作業可以自動或手動操作方式完成，執行系統運作參數同步作業的時間點包括：新增或更換一主控制器連到通訊網路時，或是運作中主控制器的系統運作參數有更新時，包括以人為操作或由遠端系統透過網路更新，或依系統控制邏輯自動更新時，即執行系統運作參數同步作業。 The system operation parameter synchronization operation can be completed automatically or manually. The time point for performing the system operation parameter synchronization operation includes: adding or replacing a main controller connected to the communication network, or operating the main controller. The system operation parameter synchronization operation is performed when the update is performed by human operation or by the remote system through the network update or automatically updated according to the system control logic.

The controller includes: an active main controller and a backup main controller, or an active light controller and a backup light controller. For example, at zero o'clock every day, the active controller and the backup controller exchange roles, that is, the active controller is changed to the backup controller role, and the original backup controller changes the role of the controller in order to keep all controllers recurring. The normal operation state; or in daily operation, multiple sets of main controllers alternately switch to the active controller role, and communicate with the signal controller to perform the light number control, thereby achieving the effect of load balancing.

實施例一Embodiment 1
如本創作所述之分離式誌控制系統，如第3圖所示，本實施例由一預設啟動主控制器1a、備援主控制器1b與至少四組路口的燈號控制器2連結其控制的號誌燈4所構成，並以一通訊線3(此處為CAN Bus)串接以電性連結各控制器。當本創作系統正常運作時，由預設啟動主控制器1a執行與各燈號控制器2間的通訊並主控號誌系統之運作，備援主控制器1b此時處於在備用待命的狀態。 As shown in FIG. 3, the present embodiment is connected to the light source controller 2 of at least four groups of intersections by a preset starting main controller 1a and a backup main controller 1b. The control light lamp 4 is constructed, and is connected in series by a communication line 3 (here, CAN Bus) to electrically connect the controllers. When the authoring system is in normal operation, the main controller 1a is activated by default to perform communication with each of the lamp controllers 2 and the operation of the master numbering system, and the backup main controller 1b is in standby standby state at this time. .
本實施例中，預設啟動主控制器1a與備援主控制器1b間每隔一時間間隔會互傳設備本身運作【狀態訊息M1】給對方，以確認彼此之運作狀態是否正常。當預設啟動主控制器1a與各路口之燈號控制器2間未進行通訊超過一預先設定的[最長未通訊允許時間]時，預設啟動主控制器1a會送出【測試訊息M2】給各個燈號控制器2，並由各個燈號控制器2的回應訊息得知其設備本身及其設備之通訊是否在正常狀態，如第4圖所示。 In this embodiment, the preset startup main controller 1a and the backup main controller 1b exchange the [status message M1] of the device itself to the other party at intervals, to confirm whether the operation states of each other are normal. When the preset start main controller 1a and the signal controller 2 of each intersection do not communicate for more than a preset [maximum non-communication allowable time], the preset start main controller 1a sends out [test message M2] to Each of the lamp controllers 2, and the response message of each of the lamp controllers 2, knows whether the communication of the device itself and its devices is in a normal state, as shown in FIG.
一種由備援主控制器1b接替預設啟動主控制器1a運作的情形是：當預設啟動主控制器1a無法與一或多組路口的燈號控制器2通訊時，例如送出【號誌控制訊息M6】給燈號控制器2無法獲得其回應時，即送出【釋放控制權訊息M5】通知備援主控制器1b及燈號控制器2其將釋放號誌 控制權，備援主控制器1b收到通知後，即送出【測試訊息M2】測試與四組路口的燈號控制器2之通訊是在正常狀態時，即發出【取得號誌控制權訊息M7】給所有控制器(含主控制器1a及燈號控制器2)，並自此時起開始接手執行主控燈號控制邏輯運算，與四組路口的燈號控制器2通訊完成號誌燈號控制作業，如第5圖所示。 A case where the backup main controller 1b takes over the operation of the preset start main controller 1a is: when the preset start main controller 1a cannot communicate with the signal controller 2 of one or more sets of intersections, for example, send [signal Control message M6] When the signal controller 2 cannot obtain its response, the [release control right message M5] is sent to notify the backup main controller 1b and the lamp controller 2 that it will release the number. After the control, the backup main controller 1b receives the notification, and sends the [test message M2] test to communicate with the signal controller 2 of the four groups of intersections. In the normal state, the [signal control information M7 is issued. 】To all controllers (including main controller 1a and signal controller 2), and from then on, start to take over the main control signal control logic operation, and communicate with the four groups of intersections of the signal controller 2 to complete the signal No. Control operation, as shown in Figure 5.
另一種由備援主控制器1b自動接替預設啟動主控制器1a運作的情形是：當預設啟動主控制器1a本身已異常無法主動送出釋放號誌控制權訊息給備援主控制器1b時，備援主控制器1b可由無法接收到預設啟動主控制器1a的定時設備本身【狀態訊息M1】通知或預設啟動主控制器1a未回應備援主控制器1b送出的【狀態訊息M1】，且備援主控制器1b再送出【詢問通訊狀態訊息M3】給四組路口的燈號控制器2，並由回應訊息確認其亦與預設啟動主控制器1a之通訊失聯時，備援主控制器1b即送出【取得主控權訊息M4】給所有控制器，並開始接手與四組路口的燈號控制器2通訊以完成號誌燈控制作業，如第6圖所示。 Another situation in which the backup main controller 1b automatically takes over the preset start main controller 1a is that when the preset start main controller 1a itself is abnormal, the release log control right message cannot be actively sent to the backup main controller 1b. When the backup main controller 1b is notified by the timing device itself [status message M1] that cannot receive the preset start main controller 1a, or the preset start main controller 1a does not respond to the [status message sent by the backup main controller 1b. M1], and the backup main controller 1b sends out [inquiry communication status message M3] to the signal controller 2 of the four groups of intersections, and confirms that it also loses communication with the preset startup main controller 1a by the response message. The backup main controller 1b sends out [obtain the master control message M4] to all the controllers, and starts to take over the communication with the signal controller 2 of the four groups of intersections to complete the control of the number of lights, as shown in Fig. 6. .
當本例之預設啟動主控制器1a運作時之系統異常或通訊異常排除後，預設啟動主控制器1a再通知備援主控制器1b要取回號誌控制權，之後即恢復由預設啟動主控制器1a接手與四組路口的燈號控制器2通訊完成號誌控制燈作業。 When the system abnormality or communication abnormality when the preset main controller 1a is started in this example is excluded, the main controller 1a is preset to notify the backup main controller 1b to retrieve the control right of the log, and then the pre-recovery is resumed. The startup main controller 1a takes over the communication with the signal controller 2 of the four groups of intersections to complete the operation of the control light.
本例之實施方式說明如下。預設啟動主控制器1a及備援主控制器1b的硬體電路相同，其示意圖如第7圖所示。二主控制器1a,1b與各路口的燈號控制器2之間以一CAN Bus連線3串接，二主控制器1a,1b之硬體包含：一控制單元電路11：包含微處理器111及記憶體112，執行號誌系統之控 制邏輯，並透過通訊單元電路12與燈號控制器2送收控制命令及狀態資訊；一通訊單元電路12：包含訊號調變/解調電路，將串列通信信號調變為載波信號，或將載波信號解調為串列通信信號，與控制單元電路11以電性連結，並以通訊線3(本例為CAN Bus)傳送載波信號；除以通訊線3串接各個控制器之外，並具備外部通訊線路5(本例為Ethernet)連接ADSL設備與外部交通控制中心的管理系統通訊，以接收交控中心由遠端下達的控制命令及回報異常狀態資訊。 The embodiment of this example is explained below.
