The present invention relates to a traffic signal device in which a signal lamp can be easily added as required.
従来の交通信号装置として、例えば、図5及び図6の(a)、(b)に示すようなものがある。図5において、信号灯器1における赤2R、黄2Y及び緑2Gの各灯器を点灯させる電力が、信号灯器制御機3から前記信号灯器1における各灯器2R,2Y,2G毎にケーブル4を介して供給されている。図5の信号灯器1は、3個の灯器2R,2Y,2Gを備えた車両用信号灯器の場合を示している。歩行者用の場合は、灯器数は2個となる。   As a conventional traffic signal device, for example, there are devices shown in FIGS. 5 and 6 (a) and (b). In FIG. 5, the electric power for lighting the red 2R, yellow 2Y and green 2G lamps in the signal lamp 1 is supplied from the signal lamp controller 3 to the lamps 2R, 2Y and 2G in the signal lamp 1. Is supplied through. The signal lamp device 1 of FIG. 5 shows a case of a vehicle signal lamp device including three lamp devices 2R, 2Y, and 2G. In the case of pedestrian use, the number of lamps is two.
信号灯器制御機3には、商用電源を用いて各部に必要な電力を供給する電源部5、信号灯器1における各灯器2R,2Y,2Gの点灯順序や、点灯時間等を記憶している制御部6、及び該制御部6から指令された点灯信号に対応する開閉素子を制御して、前記電源部5から入力された点灯用電力(AC100V)を外部端子に出力する灯器開閉部7等が備えられている。信号灯器制御機3には、信号灯器1毎及び灯色毎に専用の外部端子があり、該外部端子から信号灯器1における各灯器2R,2Y,2G毎に前記ケーブル4による配線が行われている。   The signal lamp controller 3 stores a power supply unit 5 for supplying necessary power to each unit using a commercial power supply, lighting sequences of the lamps 2R, 2Y, 2G in the signal lamp unit 1, lighting times, and the like. The lamp opening / closing unit 7 which controls the control unit 6 and the switching element corresponding to the lighting signal commanded from the control unit 6 and outputs the lighting power (AC100V) input from the power supply unit 5 to the external terminal. Etc. are provided. The signal lamp controller 3 has a dedicated external terminal for each signal lamp 1 and each lamp color, and wiring by the cable 4 is performed for each lamp 2R, 2Y, 2G in the signal lamp 1 from the external terminal. ing.
信号灯器制御機3は、交通管制センターから伝送部を介して公衆回線により接続されており、この接続により当該信号灯器制御機3の制御及び動作状態の管理が交通管制センターで行われている。   The signal lamp controller 3 is connected by a public line from the traffic control center via a transmission unit, and the control of the signal lamp controller 3 and management of the operation state are performed at the traffic control center by this connection.
図6の(a)、(b)は、交差点における4基の信号灯器1a〜1dと信号灯器制御機3との接続関係を示している。図6(b)に示すように、信号灯器制御機3から同時に点灯する信号灯器1aと1b,1cと1dの各灯器1R,1Y,1G,2R,2Y,2G毎にケーブルによる配線が行われている。このように、同時に制御される信号灯器1aと1b,1cと1dは、前記信号灯器制御機3の同一端子に接続されている。いま、例えば、信号灯器1aと1bにおける各1Gの灯器を点灯させる場合は、信号灯器制御機3における1Gの出力端子に、外部の商用電源から入力された点灯用電力(AC100V)が出力される。   6A and 6B show the connection relationship between the four signal lamps 1a to 1d and the signal lamp controller 3 at the intersection. As shown in FIG. 6 (b), the signal lamps 1a and 1b, 1c and 1d that are turned on simultaneously from the signal lamp controller 3 are wired by cables for each of the lamps 1R, 1Y, 1G, 2R, 2Y, and 2G. It has been broken. Thus, the signal lamps 1a and 1b, 1c and 1d controlled simultaneously are connected to the same terminal of the signal lamp controller 3. Now, for example, when lighting each 1G lamp in the signal lamps 1a and 1b, lighting power (AC100V) input from an external commercial power source is output to the 1G output terminal in the signal lamp controller 3. The
また、後述する図4の(a)、(b)に示すような、交通流の変更を行う場合、交差点には、その交差点に対応した信号灯器の点灯順序と点灯時間を記憶した信号灯器制御機が設置されている。該信号灯器制御機相互間の同期をとることによって交通流を制御している。同期の取り方としては、有線方式と内部時計の時刻により開始時間を合わせる方式とがある。   In addition, when changing traffic flow as shown in FIGS. 4A and 4B, which will be described later, the signal lamp control that stores the lighting sequence and lighting time of the signal lamp corresponding to the intersection at the intersection. A machine is installed. The traffic flow is controlled by synchronizing the signal light controller with each other. As synchronization methods, there are a wired method and a method in which the start time is adjusted according to the time of the internal clock.
そして、交通流の変更を行う場合は、次のような作業を必要としている。即ち、(1)信号灯器制御機における記憶情報の変更;点灯順序が変更してしまうためである。(2)点灯出力の変更;点灯順序の変更で出力する信号灯器数が変更になる場合があるからである。(3)信号灯器に対する配線の変更;前記(1)、(2)の変更に伴い、同時点灯する信号灯器が変わってしまうためである。このように、配線を変えてしまうため、元の制御に戻す場合は上記と同じ作業が必要になる。   And when changing traffic flow, the following work is required. That is, (1) change of stored information in the signal lamp controller; the lighting order is changed. (2) Change in lighting output; the number of signal lamps to be output may be changed by changing the lighting order. (3) Change of wiring for signal lamp; This is because the signal lamps that are turned on at the same time change in accordance with the changes of (1) and (2). In this way, since the wiring is changed, the same operation as described above is required when returning to the original control.
また、交通信号装置に関連する従来技術として、例えば次のような交通信号システムが知られている。この従来技術における交通信号機には、太陽光パネルもしくは風力発電機の単体又は太陽光パネル及び風力発電機の複合体とバッテリとからなる独立電源と、該独立電源と商用電源との切り替えを制御するための制御装置と、前記独立電源の電圧、電流、内部抵抗、比重等を測定するための独立電源状態測定部と、灯器の電圧値や電流値を測定するための灯器状態測定部とが備えられている。また、該交通信号機を遠隔監視及び遠隔制御するための管理装置が遠方に設置され、前記交通信号機と前記管理装置とが電気通信回線を介して接続されて、前記独立電源状態測定部及び前記灯器状態測定部の各測定値が前記管理装置に配信されるようにしている。   Further, as a conventional technique related to a traffic signal device, for example, the following traffic signal system is known. The traffic signal in this prior art controls an independent power source comprising a solar panel or a wind power generator alone or a solar panel and wind power generator complex and a battery, and switching between the independent power source and a commercial power source. A control device for measuring the voltage, current, internal resistance, specific gravity and the like of the independent power source, and a lamp state measuring unit for measuring the voltage value and current value of the lamp. Is provided. In addition, a management device for remotely monitoring and controlling the traffic signal is installed remotely, and the traffic signal and the management device are connected via an electric communication line, so that the independent power supply state measuring unit and the lamp Each measurement value of the instrument state measurement unit is distributed to the management device.
そして、前記灯器状態測定部の測定値から、前記交通信号機に設置されている灯器の劣化、不良等の状態を常時遠隔で監視可能としている。この結果、灯器がいわゆる球切れの状態になる前の適切な交換時期を把握して的確なメンテナンスを講じうるとともに保守コストも削減できるようにしている(例えば、特許文献1参照)。
特開2005−310079号公報(第3〜4頁、図1〜図4)。
And the state of deterioration, defect, etc. of the lamp installed in the traffic signal can be constantly monitored remotely from the measured value of the lamp condition measuring unit. As a result, it is possible to grasp an appropriate replacement time before the lamp is in a so-called ball-out state and to perform accurate maintenance and to reduce maintenance costs (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2005-310079 (pages 3 to 4, FIGS. 1 to 4).
図5及び図6の(a)、(b)に示した従来技術に係る交通信号装置においては、信号灯器制御機に、信号灯器における各灯器の点灯順序及び点灯時間が記憶され、また、信号灯器制御機から同時に点灯する信号灯器の各灯器毎にケーブルによる配線が行われている。このため、同時に点灯している信号灯器を別々に点灯させる制御等に変更したい場合は、信号灯器制御機に記憶されている点灯順序データの変更及び信号灯器制御機と信号灯器の各灯器間のケーブルによる配線の張り直しが必要となり、かなり困難な作業となる。また、信号灯器を追加する場合は信号灯器制御機と信号灯器における各灯器間のケーブルによる配線を追加する必要があり、上記と同様にかなり困難な作業となる。さらに、交差点における信号灯器制御機群は、同時に点灯制御する信号灯器が決められていて、制御中の変更ができないように構成されている。このため、交差点における複数の信号灯器に対し複雑な交通流に的確に対応した点灯動作を行わせることは困難である。   In the traffic signal device according to the prior art shown in FIGS. 5 and 6 (a), (b), the lighting order and lighting time of each lamp in the signal lamp is stored in the signal lamp controller, Wiring with a cable is performed for each lamp of the signal lamp that is turned on simultaneously from the signal lamp controller. For this reason, if you want to change the control so that the signal lamps that are lit at the same time are turned on separately, change the lighting sequence data stored in the signal lamp controller, and between each lamp of the signal lamp controller and the signal lamp Re-wiring with a cable is necessary, which is a very difficult task. In addition, when adding a signal lamp, it is necessary to add wiring by a cable between each lamp in the signal lamp controller and the signal lamp, which is quite difficult work as described above. Further, the signal lamp controller group at the intersection is configured such that signal lamps to be turned on simultaneously are determined and cannot be changed during the control. For this reason, it is difficult to cause a plurality of signal lamps at an intersection to perform a lighting operation that accurately corresponds to a complicated traffic flow.
また、特許文献1に記載の従来技術における交通信号機と管理装置とを接続している電気通信回線は、交通信号機における独立電源の電圧、電流、内部抵抗、比重等の測定値、及び灯器の電圧値や電流値の測定値を管理装置に配信するためだけのものである。   In addition, the telecommunication line connecting the traffic signal device and the management device in the prior art described in Patent Document 1 includes the measured values of the independent power source voltage, current, internal resistance, specific gravity, etc. It is only for distributing measured values of voltage values and current values to the management device.
そこで、共通の信号灯器制御機で複数の信号灯器の点灯動作を個々に遠隔制御するとともにその点灯動作の内容の変更を容易とし、各信号灯器の点灯状態を信号灯器制御機で監視し交通流に危険が生じる組み合わせの点灯状態の場合に直ちに異常表示動作制御に移行させ、交差点等における複数の信号灯器に対し複雑な交通流に的確に対応した点灯動作を行わせ、さらに、必要により信号灯器の追加も容易に実施でき、交通信号装置の最も効果的な運用を可能とするために解決すべき技術的課題が生じてくるのであり、本発明はこの課題を解決することを目的とする。   Therefore, the lighting operation of a plurality of signal lamps is individually controlled remotely with a common signal lamp controller, and the contents of the lighting operations can be easily changed, and the lighting state of each signal lamp controller is monitored by the signal lamp controller. In the case of a combination lighting state that causes danger, immediately shift to the abnormal display operation control, and perform the lighting operation that accurately corresponds to the complicated traffic flow for multiple signal lamps at intersections etc., and if necessary, the signal lamp Therefore, a technical problem to be solved in order to enable the most effective operation of the traffic signal device arises, and the present invention aims to solve this problem.

前記信号灯器8には、さらに前記信号灯器制御機9からの点灯動作指令を受信し、また
該点灯動作指令に対応した点灯動作の確認情報を前記信号灯器制御機9に返送するための通信制御部16、及び受信した前記点灯動作指令に応じて前記3個の灯器11R,11Y,11Gを点灯制御するための点灯制御部17等が備えられている。

And a lighting controller 17 for controlling lighting of the three lamps 11R, 11Y, and 11G according to the received lighting operation command.
前記信号灯器制御機9には、前記信号灯器8側とほぼ同様の太陽電池、風力発電機及びバッテリ18等の組み合わせからなる電源部19が備えられて、商用電源の省電力化が図られている。但し、該電源部19は信号灯器8側に設置される前記電源部19と共用されてもよい。また、信号灯器制御機9には、前記信号灯器8における各灯器11R,11Y,11Gの点灯順序や点灯時間等の情報を記憶し、信号灯器8の識別記号及び灯色を指定するための制御部21、該制御部21から指示された点灯動作指令を信号灯器8への通信回線10上に送信する通信部20、遠隔地(管制センター等)からの指令を行う場合に装備されて集中制御を行うための伝送部22、及び感知器や押ボタン等の入力機器からの信号を取り込んで各種制御を行うための1/F(インタフェース)部23等が備えられている。   The signal lamp controller 9 is provided with a power source unit 19 composed of a combination of a solar cell, a wind power generator, a battery 18 and the like which is substantially the same as the signal lamp unit 8 side, so that the power of the commercial power source can be saved. Yes. However, the power supply unit 19 may be shared with the power supply unit 19 installed on the signal lamp device 8 side. The signal lamp controller 9 stores information such as lighting sequence and lighting time of the lamps 11R, 11Y, and 11G in the signal lamp 8, and designates an identification symbol and a lamp color of the signal lamp 8. The control unit 21, the communication unit 20 that transmits a lighting operation command instructed from the control unit 21 on the communication line 10 to the signal lamp 8, and concentrated when commanded from a remote place (control center, etc.) A transmission unit 22 for performing control, a 1 / F (interface) unit 23 for performing various controls by taking in signals from input devices such as sensors and push buttons, and the like are provided.

You can also
次に、上述のように構成された交通信号装置の動作を説明する。信号灯器制御機9における制御部21には、各信号灯器8の識別記号及び各信号灯器8に対する点灯順序や点灯時間を含む点灯動作情報が記憶されている。一方、各信号灯器8には、前述したように、該信号灯器8自身にそれぞれ灯器点灯用の電源部19が備えられている。前記信号灯器制御機9は、点灯動作を制御する信号灯器8に対し、該信号灯器8固有の識別記号とともに点灯動作指令を通信部20を介して通信回線10上に発信する。   Next, the operation of the traffic signal device configured as described above will be described. The controller 21 in the signal lamp controller 9 stores lighting operation information including an identification symbol of each signal lamp 8 and a lighting sequence and lighting time for each signal lamp 8. On the other hand, each signal lamp 8 is provided with a power source 19 for lighting the lamp, as described above. The signal lamp controller 9 transmits a lighting operation command to the signal lamp 8 that controls the lighting operation, along with an identification symbol unique to the signal lamp 8, on the communication line 10 via the communication unit 20.
自己の信号灯器8の識別記号及び点灯動作指令を通信制御部16に受けた信号灯器8は、点灯制御部17を作動させて前記点灯動作指令に対応した各灯器11R,11Y,11Gの点灯動作を自己が保有する電源部19を用いて実行する。該各灯器11R,11Y,11Gの点灯は、前記点灯制御部17により、LED素子からなる各灯器11R,11Y,11Gにかかる電圧又は流れる電流値を監視し、前記点灯動作指令との照合を行った上で点灯状態とする。そして、信号灯器8は、その点灯動作の確認情報を前記通信制御部16及び通信回線10を介して信号灯器制御機9に返信する。   The signal lamp 8 that has received the identification symbol of the signal lamp 8 and the lighting operation command in the communication control unit 16 operates the lighting control unit 17 to turn on the lamps 11R, 11Y, and 11G corresponding to the lighting operation command. The operation is executed using the power supply unit 19 owned by itself. When the lighting devices 11R, 11Y, and 11G are turned on, the lighting control unit 17 monitors the voltage applied to each of the lighting devices 11R, 11Y, and 11G made of LED elements or the value of the flowing current, and compares it with the lighting operation command. After turning on, turn it on. Then, the signal lamp 8 returns the confirmation information of the lighting operation to the signal lamp controller 9 via the communication control unit 16 and the communication line 10.
また、前記自己が保有する電源部19としては、自然エネルギを利用した前記太陽電池12及び風力発電機13で発電した電力が、図示しないDC−DCコンバータにより安定した直流電源とされて使用される。該太陽電池12及び風力発電機13で発電された電力に余裕があるとき、その余剰電力は、バッテリ14に充電されて夜間や無風時など、前記太陽電池12や風力発電機13の発電容量の低いときに使用される。   Further, as the power supply unit 19 owned by the self, the power generated by the solar battery 12 and the wind power generator 13 using natural energy is used as a stable DC power source by a DC-DC converter (not shown). . When there is a margin in the power generated by the solar cell 12 and the wind power generator 13, the surplus power is charged in the battery 14, and the power generation capacity of the solar cell 12 or the wind power generator 13 is at night or when there is no wind. Used when low.
また、前記信号灯器制御機9は前記バッテリ14の残量を常時監視し、一定容量以下になった場合は、該信号灯器制御機9の指令により省電力モードとして前記LED素子からなる各灯器11R,11Y,11Gの光量を落とす制御が行われる。この光量を落とす制御は、LED素子からなる各灯器11R,11Y,11Gへ流す電流値を減らしたり、パルスによる点灯動作等、電力消費量を減らすことにより行われる。   In addition, the signal lamp controller 9 constantly monitors the remaining amount of the battery 14, and when the battery 14 is below a certain capacity, each lamp unit including the LED elements is set in a power saving mode according to a command from the signal lamp controller 9. Control is performed to reduce the amount of light of 11R, 11Y, and 11G. This control for reducing the amount of light is performed by reducing the amount of current consumed by each of the lamps 11R, 11Y, 11G made of LED elements, or by reducing the power consumption, such as a lighting operation by a pulse.
さらに、電源部19はバッテリ14の容量が減ってしまい、各灯器11R,11Y,11Gの点灯制御ができない寸前になった場合は、充電器15によるバッテリ14の充電を行い、バッテリ14の充電が完了し、バッテリ残量が回復した場合は、充電器15の動作を停止し、外部電力を極力使用しないような制御が行われる。   Further, when the capacity of the battery 14 is reduced and the lighting devices 11R, 11Y, and 11G cannot be turned on, the power source 19 charges the battery 14 with the charger 15 and charges the battery 14. Is completed and the remaining battery level is restored, the operation of the charger 15 is stopped and control is performed so that external power is not used as much as possible.
次いで、「異常表示の検出と異常モードへの移行」、「交差点における信号灯器制御機と信号灯器との接続及び動作」及び「複数交差点における交通流の変更制御」の各具体例について、信号灯器制御機と信号灯器との接続及びその動作を、それぞれ図を用いて順に説明する。   Next, for each specific example of "detection of abnormal indication and transition to abnormal mode", "connection and operation of signal lamp controller and signal lamp at intersection" and "change control of traffic flow at multiple intersections", signal lamp The connection between the controller and the signal lamp and the operation thereof will be described in order with reference to the drawings.
[異常表示の検出と異常モードへの移行]
図2を用いて説明する。図2は異常表示の検出例を説明するための結線図である。共通の信号灯器制御機9に複数の信号灯器8,…が通信回線10を介して接続されている。各信号灯器8は、信号灯器制御機9から点灯動作指令とともに送られる識別記号が自己の上記識別記号と一致した場合、その点灯動作指令に対応した灯器の点灯動作を行う。
[Detection of abnormal display and transition to abnormal mode]
This will be described with reference to FIG. FIG. 2 is a connection diagram for explaining an example of abnormality display detection. A plurality of signal lamps 8,... Are connected to a common signal lamp controller 9 via a communication line 10. Each signal lamp 8 performs the lighting operation of the lamp corresponding to the lighting operation command when the identification symbol sent together with the lighting operation command from the signal lamp controller 9 coincides with its own identification symbol.
信号灯器8における灯器点灯状態の確認は、前記したように、前記点灯制御部17で各灯器にかかる電圧又は流れる電流を監視し、灯器が点灯している状態の電圧又は電流値を検出した場合は、灯器が点灯していると判断し、前記通信制御部16を通じて信号灯器制御機9へ点灯確認情報を返信する。信号灯器制御機9は、接続されている全ての信号灯器8,…より点灯確認情報を受信し、同時に点灯した場合、危険となる組み合わせになっているか否かを監視している。   As described above, the lamp lighting state in the signal lamp 8 is confirmed by monitoring the voltage applied to each lamp or the flowing current by the lighting control unit 17, and determining the voltage or current value when the lamp is lit. If detected, it is determined that the lamp is lit, and lighting confirmation information is returned to the signal lamp controller 9 through the communication control unit 16. The signal lamp controller 9 receives lighting confirmation information from all the connected signal lamps 8, and monitors whether or not the combination is in danger when it is turned on at the same time.
そして、複数の信号灯器が同時に点灯した場合、その点灯した複数の信号灯器の組み合わせが、交通流に危険が生じるおそれがあると思われる組み合わせと合致した場合には、直ちに全ての信号灯器8,…に対し事故が起きないような異常表示動作モードへの移行指令を行う。異常表示動作モードには、閃光動作、全信号灯器の赤点灯動作又は滅灯動作等を含むものとする。   When a plurality of signal lamps are lit at the same time, if the combination of the plurality of signal lamps that are lit matches a combination that may cause danger in traffic flow, all the signal lamps 8, Command to shift to abnormal display operation mode so that no accident occurs. The abnormal display operation mode includes a flash operation, a red lighting operation or a light extinguishing operation of all signal lamps.
また、信号灯器制御機9及び各信号灯器8は、定期的に該信号灯器制御機9からの指令・確認を行っており、通信回線10が断線等のトラブルによって異常が発生し、一定時間の間、指令又は確認信号を受信できなかった場合には、前記異常動作に移行する。このとき、信号灯器制御機9は全灯器に対し、点滅動作又は滅灯動作等の異常動作指令信号を発信し、該指令を受信できなかった灯器は、点灯制御部17からの指令により一定時間経過後に前記異常動作を実行する。   In addition, the signal lamp controller 9 and each signal lamp 8 regularly instruct and check from the signal lamp controller 9, and the communication line 10 is abnormal due to a trouble such as disconnection, and a certain period of time. If the command or confirmation signal cannot be received during this time, the operation proceeds to the abnormal operation. At this time, the signal lamp controller 9 transmits an abnormal operation command signal such as blinking operation or extinguishing operation to all the lamps, and the lamp that has not received the command is in response to a command from the lighting control unit 17. The abnormal operation is executed after a predetermined time has elapsed.

Since it is not necessary to supply electric power, it is possible to connect without considering the signal lamp and the lamp color that are turned on at the same time. In this specific example, connection is made by a single communication line 10 for serial communication.
信号灯器8a,8b,8c,8dの灯器点灯を行う場合は、信号灯器制御機9から各信号灯器8a,8b,8c,8dが持っている固有の識別記号及び点灯動作指令の信号をシリアル通信用の通信回線10を介して時間的な系列として逐次伝送する。   When the lamps of the signal lamps 8a, 8b, 8c, and 8d are turned on, the signal lamp controller 9 serially transmits a unique identification symbol and a lighting operation command signal possessed by each of the signal lamps 8a, 8b, 8c, and 8d. It transmits sequentially as a time series through the communication line 10 for communication.
