Description

  The present invention relates to a signal controller and a signal control program, and more particularly to a signal controller and a signal control program in a centralized traffic signal.

  At the intersection, a signal controller is installed to control lighting or extinguishing of the signal lamps such as blue, yellow and red. The signal controller usually has a rainproof casing and is installed on a utility pole beside the intersection. There are “centralized type” and “point type” signal controllers. The centralized signal controller has a function of performing information communication with a central device installed in a traffic control center or the like, and is controlled by the central device. The point type signal controller controls the signal lamp alone without performing communication with the central device.

  A centralized signal controller has a table control system and a step control system. Table control means that the central device transmits information that can determine the timing for switching the color of one or more signal lamps to the signal controller, and the signal controller itself switches the color of the signal lamp based on the information. This is control for determining timing.

  On the other hand, the step control system is a control in which the signal controller receives a step command transmitted from the central device and advances the light color of the signal lamp from blue to yellow and from yellow to red. Each time the signal controller receives a step command, the signal controller advances the lamp color of the signal lamp by one step.

  As a signal control system using a centralized signal controller and capable of determining the lamp color switching timing of signal display in consideration of the weather, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2008-27024) discloses The following techniques are disclosed. That is, the signal control system has lamp color switching timing determination means for determining the timing of turning on and off each signal lamp color in one or a plurality of signal lamps. The signal control system includes a weather type acquisition unit that acquires a weather type, and the lamp color switching timing determination unit uses the acquired weather type as one of the determination elements of the lamp color switching timing.

  First, the contents of the embodiment of the present invention will be listed and described.

  (1) In the signal controller according to the embodiment of the present invention, the receiving unit that receives the signal control command information from the central apparatus, and the control parameters included in the signal control command information received by the receiving unit are normal. A control parameter determining unit that determines whether or not there is a remote command in the signal control command information received by the receiving unit, and the control parameter determining unit determines that the control parameter is normal A first presentation control unit that performs control so that it can be recognized that the transition to the remote state, which is a state that has been performed, and a signal lamp based on the control parameter included in the signal control command information in the remote state A lamp color switching timing determination unit that determines the timing of lighting and extinguishing of each signal lamp color, and before including the remote command by the receiver And a second presentation control unit that performs control so that the signal control command information has been received is recognizable.

  Thus, for example, the signal controller does not transition to the remote state by the configuration capable of recognizing that the signal controller receives the signal control command information including the remote command and that the signal controller has transitioned to the remote state. In this case, the signal controller cannot receive the signal control command information including the remote command because it cannot receive the signal control command information. It can be determined whether or not the transition is made. Therefore, the operation | work which makes a signal controller the state which can be controlled by a central apparatus can be performed smoothly.

  (2) Preferably, the signal controller further includes a first circuit board and a second circuit board, wherein the first circuit board includes the receiving unit, and the second circuit board includes the lamp. A color switching timing determination unit is included.

  With such a configuration, for example, when there is an abnormality in the receiving unit included in the first circuit board, the first circuit board is removed and replaced while the second circuit board is mounted on the signal controller. Can do. Thereby, for example, even when there is an abnormality in the first circuit board, the control of the signal lamp by the second circuit board can be continued.

  (3) Preferably, the signal controller further recognizes that the confirmation information is transmitted to the central apparatus by transmitting the confirmation information indicating that the transition to the remote state is performed, and that the confirmation information is transmitted by the transmission unit. And a third presentation control unit that performs control that makes possible.

  Thus, when the confirmation information indicating that the signal controller has transitioned to the remote state can be recognized, for example, when the central device cannot receive confirmation information from the signal controller. Whether the signal controller has not performed processing for transmitting the confirmation information or whether the central device has not received the confirmation information even though the signal controller has performed processing for transmitting the confirmation information Can be determined.

  (4) Preferably, the signal controller further includes a first circuit board and a second circuit board, wherein the first circuit board includes the receiving unit, and the second circuit board includes the lamp. Including a color switching timing determination unit, a notification of transition to the remote state is sent from the second circuit board to the first circuit board, the signal controller is further included in the first circuit board, In response to the notification, a transmitting unit that transmits confirmation information indicating that the transition to the remote state has been performed to the central device, and a control that enables the first circuit board to recognize that the notification has been received. A fourth presentation control unit.

  As described above, for example, confirmation information from the signal controller in the central device can be obtained by the configuration capable of recognizing that the notification sent to the remote state from the second circuit board is received in the first circuit board. Is not received from the first circuit board because the notification sent from the second circuit board is not received by the first circuit board, or the confirmation information cannot be sent from the first circuit board or sent from the second circuit board. It is possible to determine whether confirmation information has not been transmitted from the first circuit board even though the notification is received by the first circuit board.

  (5) The signal controller according to the embodiment of the present invention is in a state in which the signal control command information including the remote command is received by the receiving unit that receives the signal control command information from the central apparatus and the receiving unit. A first presentation control unit that performs control such that it can be recognized that the transition to the remote state is possible, and in the remote state, according to a step command included in the signal control command information received by the reception unit A lamp color switching control unit that controls on / off of each signal lamp color in the signal lamp unit, and a step of determining whether the control by the lamp color switching control unit is normal based on the step command. In the remote state, the advance determination unit performs control so that the progress determination unit can recognize that the control has been determined to be normal by the lamp color switching control unit. And a 2 presentation control unit.

  In this way, the signal controller can recognize that the signal controller has transitioned to the remote state and that the display control in the signal lamp is determined to be normal, for example, in the signal controller's step command for the signal lamp. When the central control unit cannot confirm that the corresponding control has been performed normally, the signal controller has not transitioned to the remote state because the signal controller has not transitioned to the remote state, or the signal controller has transitioned to the remote state. Despite this, whether the control was not performed normally, or whether the signal controller changed to the remote state and the control was performed normally, but could not be confirmed in the central unit Can be determined. Therefore, the operation | work which makes a signal controller the state which can be controlled by a central apparatus can be performed smoothly.

  (6) Preferably, the lamp color switching control unit sets the contents of lighting and extinguishing of each signal lamp color in the signal lamp unit for each step, repeatedly executes a cycle composed of a plurality of the steps, and the lamp color switching The control unit receives the step command and proceeds to the next step, and the step determination unit determines whether or not the lamp color switching control unit has normally shifted for all steps included in the cycle. Determining, the stepping command corresponding to a command to shift to the first step in the cycle is received by the receiving unit, or the lamp color switching control unit shifts to the first step, Period until the determination of whether or not the lamp color switching control unit has normally shifted for all the steps included in the cycle is performed by the progress determination unit And a third display control unit that performs control such that it is possible to recognize it.

  In this way, with the configuration capable of recognizing that the process is until the cycle determination is performed in the signal controller, for example, it is possible to recognize that the cycle determination has not been reached due to the occurrence of an abnormality.

  (7) Preferably, the signal controller further includes a first circuit board and a second circuit board, wherein the first circuit board includes the receiving unit, and the second circuit board includes the lamp. Includes a color switching control unit.

  With such a configuration, for example, when there is an abnormality in the receiving unit included in the first circuit board, the first circuit board is removed and replaced while the second circuit board is mounted on the signal controller. Can do. Thereby, even when there is an abnormality in the first circuit board, the control of the signal lamp by the second circuit board can be continued.

  (8) More preferably, the signal control command information received by the receiving unit is transmitted from the first circuit board to the second circuit board, and the first presentation control unit is transmitted from the first circuit board. When the second circuit board confirms that the remote command is included in the received signal control command information, control is performed so as to recognize that the remote state has been changed, and the signal control is performed. The machine further includes a fourth presentation control unit that performs control so that the reception unit can recognize that the signal control command information including the remote command has been received.

  As described above, the signal control command information including the remote command transmitted from the central device is received by the first circuit board, and the signal control command information including the remote command transmitted from the first circuit board is set to the second circuit. For example, when the signal controller does not step, the signal control command information including the remote command from the central device cannot be received by the first circuit board due to the configuration capable of recognizing that it has been received on the board. The second remote command sent from the first circuit board is second even though the signal controller has not transitioned to the remote state or the signal control command information including the remote command has been received by the first circuit board. The signal controller has not transitioned to the remote state because it has not been received at the circuit board, or the signal controller has transitioned to the remote state upon receipt of a remote command at the second circuit board. Warazu can signal controller to determine whether not to perform increment.

  (9) Preferably, the signal controller further includes a fifth presentation control unit that performs control such that the content of the signal control command information received by the receiving unit can be recognized.

Identification becomes easy.

  (10) Preferably, the signal controller performs visual presentation as the control that enables recognition.

  With such a configuration, for example, in the installation work of the signal controller, it is possible to identify the abnormal contents without connecting a personal computer or the like to the signal controller, so that the signal controller can be controlled by the central device. Can be performed more smoothly.

  (11) A program according to an embodiment of the present invention is a signal control program used in a signal controller, wherein the signal control includes a step of receiving signal control command information from a central device in a computer, and a remote command.

And a step of.

  Thus, for example, the signal controller does not transition to the remote state by the configuration capable of recognizing that the signal controller receives the signal control command information including the remote command and that the signal controller has transitioned to the remote state. In this case, the signal controller cannot receive the signal control command information including the remote command because it cannot receive the signal control command information. It can be determined whether or not the transition is made. Therefore, the operation | work which makes a signal controller the state which can be controlled by a central apparatus can be performed smoothly.

  (12) A program according to an embodiment of the present invention is a signal control program used in a signal controller, wherein the signal control includes a step of receiving signal control command information from a central device in a computer and a remote command.

  In this way, the signal controller can recognize that the signal controller has transitioned to the remote state and that the display control in the signal lamp is determined to be normal, for example, in the signal controller's step command for the signal lamp. When the central control unit cannot confirm that the corresponding control has been performed normally, the signal controller has not transitioned to the remote state because the signal controller has not transitioned to the remote state, or the signal controller has transitioned to the remote state. Despite this, whether the control was not performed normally, or whether the signal controller changed to the remote state and the control was performed normally, but could not be confirmed in the central unit Can be determined. Therefore, the operation | work which makes a signal controller the state which can be controlled by a central apparatus can be performed smoothly.

<First Embodiment>
The present embodiment relates to a table control type traffic signal control system.

[System configuration]
FIG. 1 is a diagram showing a configuration of a traffic signal control system according to a first embodiment of the present invention.

  With reference to FIG. 1, the traffic signal control system 801 includes a central device 101, a signal controller 201, a signal lamp 501, and a vehicle detector 601.

  The signal controller 201 is communicatively connected to the central apparatus 101 via a predetermined communication line. The signal lamp 501 and the vehicle detector 601 are electrically connected to the signal controller 201.

  The signal lamp device 501 switches a signal lamp color such as red, blue, or yellow, and displays a signal to the driver or pedestrian of the automobile. The signal controller 201 performs control to repeat switching of the signal lamp color of the signal lamp unit 501 at a predetermined time interval.

  The vehicle detector 601 detects the presence of a vehicle and transmits detector information that is information based on the detection result to the signal controller 201. The detector information includes sensing pulse information indicating the presence or absence of the vehicle at a predetermined time at the detection point, the count of vehicles that passed the detection point per unit time, or the presence of a vehicle per unit time at the detection point. Including ratio. The signal controller 201 switches the lamp color of the signal lamp 501 based on the detector information transmitted from the vehicle detector 601 and the signal control command information transmitted from the central apparatus 101.

  The signal lamp 501 is an assembly of signal lamps controlled by one signal controller, such as a group of a plurality of signal lamps installed at an intersection. The vehicle detector 601 is a collection of vehicle detectors that transmit signals to one signal controller.

  The central apparatus 101 transmits signal control command information to the signal controller 201. The signal control command information in the table control method includes control parameters such as cycle length, offset, number of indications, and split. The signal controller 201 actually determines the lamp color switching timing of the signal lamp unit 501 based on the signal control command information. The central apparatus 101 transmits signal control command information including a remote command in order to cause the signal controller 201 to transition to a remote state. The remote state is a state that can be controlled by the signal controller 201, in which the signal controller 201 transitions by receiving signal control command information including a remote command and normal control parameters. Hereinafter, the remote state in the table control type signal controller 201 is also referred to as a remote state A.

  The signal controller 201 sets the contents of lighting and extinguishing of each signal lamp color in the signal lamp unit 501 for each step. Here, the cycle length, which is a control parameter, is the time required for one step to complete a cycle. The offset is a difference given to the cycle start time by each signal controller when the central apparatus 101 controls the signal controllers at a plurality of intersections in association with each other. In order to avoid the danger of traffic flows crossing each other at intersections, a traffic right is assigned to each traffic flow. A current display is a group of traffic flows that are given the right of traffic for multiple traffic flows that pass through the intersection where the signal is installed, or a time zone in which the right of traffic is assigned to a group of the traffic flows. Say. The term “split” refers to the time ratio of each display in one cycle.

The signal controller 201 transmits confirmation information indicating a history of switching the lamp color of the signal lamp 501 to the central apparatus 101. The confirmation information includes information indicating whether or not the signal controller 201 is in the remote state A. Further, when the signal controller 201 enters the remote state A, the signal controller 201 turns on an LED for presenting the remote state A (hereinafter also referred to as a state LED).
[Task]

  By the way, for example, when a signal controller is newly installed, the installation operator determines whether the signal controller 201 has received the signal control command information from the central apparatus 101 and has entered the remote state A. It is necessary to confirm.

  The installation worker of the signal controller 201 first communicates with the maintenance worker of the central apparatus 101 by a mobile phone or the like, and notifies that the signal controller 201 is ready to receive a remote command. Then, the maintenance worker of the central apparatus 101 is requested to transmit a remote command. Then, the maintenance worker of the central apparatus 101 transmits a remote command from the central apparatus 101 to the signal controller 201 and notifies the installation operator of the signal controller 201 of the transmission. When a remote command is transmitted from the central device 101 and the signal controller 201 that has received the remote command transitions to the remote state A, the status LED is lit. The installation operator of the signal controller 201 can recognize that the signal controller 201 is in the remote state A by confirming the lighting of the state LED.

  However, even if the maintenance worker of the central apparatus 101 notifies the installation worker of the signal controller 201 that the remote command has been transmitted to the signal controller 201, the signal controller 201 is remote. There is a case where the state LED does not turn on without transitioning to the state A.

  For example, if the maintenance worker of the central apparatus 101 mistakenly transmits a remote command to another signal controller, the signal controller 201 does not transition to the remote state A because it has not received the remote command.

  Further, for example, the signal controller 201 is used when there is an abnormality in the transmission path between the central device 101 and the signal controller 201 even when the central device 101 actually transmits a remote command to the signal controller 201. Does not transition to the remote state A because the remote command cannot be recognized.

  Further, control parameters such as the split and the number of indications are stored in advance on the circuit board of the signal controller 201. Even when the signal controller 201 receives the signal control command information from the central device 101, when the control parameter indicated by the signal control command information does not match the control parameter stored in the circuit board, etc. The remote state A is not changed according to the defined standard.

  When the signal controller 201 does not transit to the remote state A, the installation operator of the signal controller 201 cannot easily identify where the abnormality is. An operator who installs the signal controller 201 needs to specify an abnormal part by connecting a personal computer or the like to the signal controller 201 and confirming an operation history of the signal controller 201 in order to identify an abnormal part. There is.

  On the other hand, when the signal controller 201 transitions to the remote state A, the signal controller 201 transmits confirmation information indicating the transition to the remote state A to the central apparatus 101. However, when the central apparatus 101 cannot receive the confirmation information from the signal controller 201, the maintenance worker of the central apparatus 101 cannot easily identify where the abnormality is. For example, the maintenance worker of the central apparatus 101 cannot distinguish whether the signal controller 201 is abnormal or whether the transmission quality between the central apparatus 101 and the signal controller 201 is abnormal.

  Therefore, in the traffic signal control system 801 according to the first embodiment of the present invention, when the signal controller 201 does not switch to the remote state A, the presentation that supports the identification of the abnormality that has occurred is performed.

[Configuration and basic operation of signal controller]
FIG. 2 is an example of a table showing signal lamp color steps in the traffic signal control system according to the first embodiment of the present invention.

  Referring to FIG. 2, the table shows the number of seconds in each step and the signal lamp color on the main road and the secondary road. The main road is, for example, a road with a large amount of traffic among two intersecting roads. The secondary road is a road that intersects with the main road and has less traffic than the main road. The signal controller 201 sets the contents of lighting and extinguishing of each signal lamp color in the signal lamp unit 501 for each step. “PG” indicates a state in which the pedestrian signal is blue and the vehicle signal is blue. “PF” indicates that the pedestrian signal is blinking and the vehicle signal is blue. “PR” indicates a state in which the pedestrian signal is red and the vehicle signal is blue. “Y” indicates a state in which the pedestrian signal is red and the vehicle signal is yellow. “A” indicates a state in which the pedestrian signal is red and the vehicle blue arrow signal is lit. “R” indicates that the pedestrian signal is red and the vehicle signal is red.

  The signal controller 201 determines and stores the number of seconds for each step based on the detector information received from the vehicle detector 601 and the signal control command information received from the central device 101. Then, the signal controller 201 counts the number of seconds in the current step, and when the number of seconds in the stored step is reached, proceeds to the next step.

  The signal controller 201 advances the steps shown in the table from step 1 to step 12 step by step. When the signal controller 201 proceeds the step to step 12, the signal controller 201 proceeds to step 1. Thereafter, the signal controller 201 advances the step again to the next step step by step. Hereinafter, the last step of the table, here step 12 is also referred to as the final step. The first step of the table, here step 1 is also referred to as the first step. A group of steps from the first step to the last step is also referred to as one cycle. Note that the number of steps in one cycle differs depending on the size of an intersection where the signal controller 201 is installed, for example.

  FIG. 3 is a diagram showing the configuration of the signal controller according to the first embodiment of the present invention.

  With reference to FIG. 3, the signal controller 201 includes a communication control unit 301 and a lamp control unit 401. The communication control unit 301 includes a reception unit 11, a reception presentation control unit (second presentation control unit) 12, an inter-board reception presentation control unit (fourth presentation control unit) 13, and a transmission presentation control unit (third presentation control). Part) 14, the transmission part 15, and LED31,33,34. The lamp control unit 401 includes a control parameter determination unit 21, a state switching unit 22, a lamp color switching timing determination unit 23, a lamp color switching control unit 24, and a state presentation control unit (first presentation control unit) 25. , Storage unit 27 and LED 32.

  The receiving unit 11 receives the signal control command information including the remote command from the central apparatus 101 and sends the command reception information indicating that the signal control command information including the remote command has been received to the reception presentation control unit 12.

  The reception presentation control unit 12 receives the command reception information and performs control such that the reception unit 11 can recognize that the signal control command information including the remote command has been received. Specifically, the reception presentation control unit 12 receives the command reception information from the reception unit 11 and turns on the LED 31.

  In addition, the reception unit 11 sends the signal control command information received from the central apparatus 101 to the control parameter determination unit 21. The control parameter determination unit 21 receives the signal control command information, determines whether or not the control parameter included in the signal control command information is normal, and sends determination result information indicating the determination result to the state switching unit 22. Specifically, the control parameter determination unit 21 determines that the control parameter stored in advance in the storage unit 27 matches the control parameter included in the signal control command information, or the difference between the two control parameters is within a predetermined range. Or the like, it is determined that the control parameter included in the signal control command information is normal.

  In addition, the receiving unit 11 sends the signal control command information received from the central apparatus 101 to the state switching unit 22. When it is determined that the remote control is included in the signal control command information received by the receiving unit 11 and the control parameter is normal, the state switching unit 22 moves the signal controller 201 to the remote state A. Transition.

  Specifically, the state switching unit 22 receives the signal control command information including the remote information from the receiving unit 11 and the determination result indicating that the control parameter is normal from the control parameter determining unit 21. When the determination result information shown is received, the signal controller 201 is shifted to the remote state A.

Switch. In addition, the signal lamp device 501 may display not only a circular shape as a signal lamp color but also an arrow and the whole or a part of a person.

  The transmission unit 15 sends the state transition notification received from the state switching unit 22 to the inter-board reception presentation control unit 13. In addition, the transmission unit 15 receives a state transition notification from the state switching unit 22, creates confirmation information including the state transition notification, and transmits the confirmation information to the central apparatus 101. In addition, the transmission unit 15 transmits notification transmission information indicating that the confirmation information including the state transition notification is transmitted to the central apparatus 101 to the transmission presentation control unit 14.

  The inter-board reception presentation control unit 13 receives the state transition notification from the transmission unit 15 and performs control such that it can be recognized that the state transition notification has been received. Specifically, the inter-board reception presentation control unit 13 receives the state transition notification from the transmission unit 15 and turns on the LED 33.

  The transmission presentation control unit 14 receives the notification transmission information and performs control so that the transmission unit 15 can recognize that the confirmation information including the state transition notification has been transmitted.

[Operation]
The signal controller according to the first embodiment of the present invention reads and executes a program including a part or all of each step of the following sequence from a memory (not shown). This program can be installed externally. The installed program is distributed in a state stored in a recording medium, for example.

  FIG. 9 is a diagram illustrating an example of a sequence in which the signal controller according to the first embodiment of the present invention transitions to the remote state A.

  Referring to FIG. 9, first, central apparatus 101 transmits signal control command information to communication control unit 301 (step S11).

  Next, the communication control unit 301 receives the signal control command information from the central apparatus 101, and confirms whether the signal control command information includes a remote command (step S12).

  Next, when it is confirmed that the signal control command information includes a remote command (YES in step S12), the communication control unit 301 turns on the LED 31 (step S13). If the LED 31 has already been lit, the communication control unit 301 continues the lit state. Thereby, the communication control unit 301 presents that the signal control command information including the remote command has been received.

  On the other hand, when it is confirmed that the signal control command information does not include the remote command (NO in step S12), the communication control unit 301 turns off the LED 31 (step S14). If the LED 31 is already turned off, the communication control unit 301 continues the turned off state.

  Next, the communication control unit 301 sends the signal control command information received from the central apparatus 101 to the lamp control unit 401 (step S15).

  Next, the lamp control unit 401 receives the signal control command information and determines whether a condition for causing the signal controller 201 to transition to the remote state A is satisfied (step S16). Specifically, the lamp control unit 401 determines whether or not the signal control command information includes a remote command and the control parameter included in the signal control command information is normal.

  Next, when it is determined that the condition for causing the signal controller 201 to transition to the remote state A is satisfied, the lamp control unit 401 causes the signal controller 201 to transition to the remote state A (step S17).

  Next, the lamp control unit 401 turns on the LED 32 (step S18). If the LED 32 is already lit, the lamp control unit 401 continues the lit state. Thereby, the signal controller 201 is informed that it is in the remote state A (step S18).

  Next, the lamp control unit 401 sends a state transition notification to the communication control unit 301 (step S19).

  Next, the communication control unit 301 receives the state transition notification and turns on the LED 33 to indicate that the communication control unit 301 has received the state transition notification (step S20). That is, the communication control unit 301 in the communication control board 351 presents that the communication control board 351 has received the state transition notification.

  Next, the communication control unit 301 creates confirmation information including a state transition notification and transmits it to the central apparatus 101 (step S21).

  Next, the communication control unit 301 determines whether or not the transmission of the confirmation information to the central apparatus 101 has succeeded (step S22).

  Next, when the communication control unit 301 determines that the transmission of the confirmation information to the central apparatus 101 is successful, the communication control unit 301 turns on the LED 34 (step S23). If the LED 34 has already been lit, the communication control unit 301 continues the lit state. As a result, the communication control unit 301 presents that the confirmation information has been transmitted to the central apparatus 101.

  On the other hand, if the communication control unit 301 determines that the transmission of the confirmation information to the central apparatus 101 has failed, the communication control unit 301 turns off the LED 34 (step S24). When the LED 34 is already turned off, the communication control unit 301 continues the turned off state.

  On the other hand, when it is determined that the condition for causing the signal controller 201 to transition to the remote state A is not satisfied (NO in step S16), the lamp controller 401 performs a single operation on the signal controller 201. (Step S25). The single operation is an operation of controlling the lamp color of the signal lamp 501 with a fixed pattern stored in advance when the signal controller 201 is not in a remote state.

  FIG. 10 is a diagram illustrating an example of a sequence in the case where the signal controller 201 performs a single operation in step S25 illustrated in FIG.

  Referring to FIG. 10, first, the lamp control unit 401 causes the signal controller 201 to perform a single operation (step S31).

  Next, the lamp control unit 401 turns off the LED 32 (step S32). When the LED 32 is already turned off, the lamp control unit 401 continues the turned off state.

  Next, the lamp control unit 401 sends single operation information indicating that the signal controller 201 is performing single operation to the communication control unit 301 (step S33).

  Next, the communication control unit 301 receives the single operation information from the lamp control unit 401 and turns off the LED 33 (step S34). If the LED 33 has already been turned off, the communication control unit 301 continues to be turned off.

  Next, the communication control unit 301 turns off the LED 34 (step S35). If the LED 34 has already been turned off, the communication control unit 301 continues to be turned off.

  FIG. 11 is a diagram illustrating an example of the relationship between the state of each LED and the content of abnormality in the signal controller according to the first embodiment of the present invention.

  For example, the installation worker of the signal controller 201 has received a notification from the maintenance worker of the central apparatus 101 that confirmation information indicating that the signal controller 201 has transitioned to the remote state A has not been received by the central apparatus 101. In the case, the state of the LEDs 31 to 34 is confirmed, and the abnormality content is determined.

  Referring to FIG. 11, when LEDs 31, 32, 33, and 34 are off, there is an abnormality between central apparatus 101 and signal controller 201, or signal control command information including a remote command is transmitted from central apparatus 101. As a result, the signal controller 201 can determine that it has not transitioned to the remote state A. The abnormality between the central apparatus 101 and the signal controller 201 is a case where normal communication is not performed due to a transmission quality problem between the central apparatus 101 and the signal controller 201, for example.

  Further, when the LED 31 is on and the LEDs 32, 33, and 34 are off, there is an abnormality in information transmission from the communication control unit 301 to the lamp control unit 401, or the control parameter included in the signal control command information Due to the abnormality, it can be determined that the signal controller 201 has not transitioned to the remote state A.

  When the LEDs 31 and 32 are on and the LEDs 33 and 34 are off, the signal controller 201 is in the remote state A, but there is an abnormality in information transmission from the lamp control unit 401 to the communication control unit 301. Thus, it can be determined that the confirmation information cannot be transmitted to the central apparatus 101.

  When the LEDs 31, 32, and 33 are on and the LED 34 is off, the signal controller 201 is in the remote state A, but there is an abnormality between the signal controller 201 and the central device 101, so that the central device 101 It can be determined that the confirmation information has not been transmitted to.

  When the LEDs 31, 32, 33, and 34 are on, the signal controller 201 has transitioned to the remote state A and has transmitted confirmation information to the central apparatus 101.

  The signal control command information may be transmitted as one data or may be transmitted as a plurality of divided data. When the data is transmitted as a plurality of data, the transmission interval of each data may be free.

  Further, the control parameter included in the signal control command information transmitted from the central apparatus 101 may be information indicating the parameter value itself, or information specifying a specific pattern among a plurality of predetermined patterns. It may be. Further, the control parameter may be information specifying an allowable range.

  Further, the lamp color switching control unit 24 detects information indicating the timing from the lamp color switching timing determination unit 23 and the presence of the vehicle from the vehicle detector 601 when determining the timing for switching the lamp color of the signal lamp 501. In addition to the information indicating that the signal controller 201 has been used, a constant or the like inherent in the signal controller 201 may be used.

  For example, for the time when the signal color of the signal lamp 501 is yellow, a constant that the signal controller 201 has uniquely may be used.

  By the way, since the centralized traffic signal is controlled by the central device, for example, when installing a new traffic signal, the installation operator confirms that the signal controller can be controlled by the central device. There is a need. However, the signal controller may not be able to be controlled by the central device due to an abnormality in a signal received from the central device or an abnormality in the signal controller itself. In such a case, the installation operator has spent a lot of time identifying the abnormal content.

  On the other hand, in the signal controller according to the first embodiment of the present invention, the reception unit 11 receives signal control command information from the central apparatus 101. The control parameter determination unit 21 determines whether or not the control parameter included in the signal control command information received by the reception unit 11 is normal. The state presentation control unit 25 performs control such that the signal controller 201 can recognize that the signal controller 201 has transitioned to the remote state A. In the remote state A, the lamp color switching timing determination unit 23 determines the timing of turning on and off each signal lamp color in the signal lamp unit 501 based on the control parameter included in the signal control command information. The reception presentation control unit 12 performs control such that the reception unit 11 can recognize that the signal control command information including the remote command has been received.

  In this way, the signal controller 201 can recognize that the signal control command information including the remote command has been received and that the signal controller 201 has transitioned to the remote state A. When the signal controller 201 does not transition to the state A, the signal controller 201 cannot receive the signal control command information including the remote command, and therefore the signal controller 201 does not transition to the remote state A or can receive the signal control command information including the remote command. However, it can be determined whether or not the remote state A is not changed. Therefore, it is possible to smoothly perform the operation of setting the signal controller 201 in a state where it can be controlled by the central device 101.

  In the signal controller according to the first embodiment of the present invention, the communication control board 351 includes the receiving unit 11. The lamp control board 451 includes a lamp color switching timing determination unit 23.

  With such a configuration, for example, when there is an abnormality in the receiving unit 11 included in the communication control board 351, the communication control board 351 is removed and replaced while the lamp control board 451 is mounted on the signal controller 201. And so on. Thereby, for example, even when the communication control board 351 is abnormal, the control of the signal lamp 501 by the lamp control board 451 can be continued.

  Further, in the signal controller according to the first embodiment of the present invention, the transmission unit 15 transmits confirmation information indicating that the state has changed to the remote state A to the central apparatus 101. The transmission presentation control unit 14 performs control such that it can be recognized that the confirmation information has been transmitted by the transmission unit 15.

  Thus, for example, the confirmation information from the signal controller 201 in the central device 101 can be recognized by the configuration capable of recognizing that the confirmation information indicating that the signal controller 201 has transitioned to the remote state A has been transmitted to the central device 101. In the central apparatus 101, the signal controller 201 has not performed the process for transmitting the confirmation information or the signal controller 201 has performed the process for transmitting the confirmation information. It can be determined whether confirmation information has not been received.

  In the signal controller according to the first embodiment of the present invention, the communication control board 351 includes the receiving unit 11. The lamp control board 451 includes a lamp color switching timing determination unit 23. The notification of the transition to the remote state A is sent from the lamp control board 451 to the communication control board 351. The transmission unit 15 is included in the communication control board 351, receives the notification, and transmits confirmation information indicating the transition to the remote state A to the central apparatus 101. The inter-board reception presentation control unit 13 performs control so that the communication control board 351 can recognize that the notification has been received.

  As described above, the central device 101 receives the notification from the lamp control board 451 that the transition to the remote state A has been received by the communication control board 351 from the signal controller 201. If the confirmation information cannot be received, the notification sent from the lamp control board 451 is not received by the communication control board 351, so that the confirmation information cannot be sent from the communication control board 351, or the lamp control board 451. Although the communication control board 351 receives the notification sent from the communication control board 351, it can be determined whether the confirmation information has not been sent from the communication control board 351.

  In the signal controller according to the first embodiment of the present invention, visual presentation is performed as the control that can be recognized.

  With such a configuration, for example, in the installation work of the signal controller 201, it is possible to identify the abnormality content without connecting a personal computer or the like to the signal controller 201. Therefore, the signal controller 201 is controlled by the central device 101. It is possible to more smoothly perform the operation to obtain a state that can be performed.

  Next, another embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated.

<Second Embodiment>
The present embodiment relates to a traffic signal control system of a step control system. The contents other than those described below are the same as those in the traffic signal control system according to the first embodiment.

[System configuration]
A traffic signal control system 802 according to the second embodiment of the present invention includes a central device 102 instead of the central device 101, and includes a signal controller 202 instead of the signal controller 201.

  The central device 102 transmits signal control command information including a command for the signal controller 202 to the signal controller 202. The signal controller 202 transitions to a remote state when receiving signal control command information including a remote command. The remote state is a state that can be controlled by the central apparatus 102 that transitions by receiving signal control command information including a remote command. Hereinafter, the remote state in the signal controller 202 of the step control method is also referred to as a remote state B. When the signal controller 202 receives the signal control command information including the step command in the remote state B, the signal controller 202 switches the contents of each signal lamp color on and off in the signal lamp unit 501.

  Specifically, when the signal controller 202 receives the signal control command information including the step command in the remote state B, the signal controller 202 advances the step shown in FIG. That is, the signal controller 202 moves to the next step in response to the step command. The step command corresponds to a command to shift to the next step. Unlike the signal controller 201 of the table control system, the signal controller 202 does not store the number of seconds of each step, and moves to the next step depending on the timing of receiving the signal control command information including the step command. To do. Hereinafter, proceeding from one step to the next is also referred to as stepping.

  When the signal controller 202 transitions to the remote state B, the signal controller 202 turns on a state LED for presenting the transition to the remote state B. In addition, the signal controller 202 transmits confirmation information including the floor information indicating the current step to the central apparatus 102. The central device 102 receives this confirmation information and recognizes that the signal controller 202 has shifted to the next step.

[Task]
By the way, for example, when a signal controller is newly installed, the installation operator determines whether the signal controller 202 receives the signal control command information from the central device 102 and enters the remote state B. In addition to checking, it is necessary to check whether or not the step is normally performed through one cycle from the first step to the last step.

  The installation operator of the signal controller 202 first contacts the maintenance operator of the central apparatus 102 with a mobile phone or the like, and requests transmission of signal control command information including a remote command and a step command. The maintenance worker of the central device 102 transmits signal control command information including a remote command and a step command from the central device 102 to the signal controller 202.

  The signal controller 202 receives the signal control command information, transitions to the remote state B, and turns on the state LED. The installation operator of the signal controller 202 can recognize that the signal controller 202 has transitioned to the remote state B by confirming the lighting of the state LED. In addition, the signal controller 202 proceeds to the next step in accordance with the step command included in the signal control command information. Then, the signal controller 202 transmits confirmation information including the floor information to the central device 102.

  Subsequently, the central device 102 transmits signal control command information including a step command to the signal controller 202. The signal controller 202 receives the signal control command information including the step command, moves to the next step, and transmits confirmation information including the floor information to the central device 102.

  The central device 102 transmits signal control command information including a step command to the signal controller 202, for example, 12 times in order to make the signal controller 202 step from the first step to the last step. Each time the signal controller 202 receives the signal control command information including the step command, the signal controller 202 proceeds to the next step and transmits the confirmation information including the floor information to the central device 102.

  When the central device 102 transmits signal control command information for one cycle that causes the signal controller 202 to step from the first step to the last step, the central device 102 determines whether or not the signal controller 202 has normally stepped. . Specifically, the central device 102 determines whether or not the number of times that the signal control command information including the step command is transmitted matches the number of steps of the signal controller 202 indicated in the confirmation information. judge.

  When the central controller 102 determines that the signal controller 202 has been normally advanced, the signal controller 202 installation worker receives a communication from the maintenance worker of the central apparatus 102 and receives the signal controller 202. It can be confirmed that the stepping in was successfully performed.

  However, the installation operator of the signal controller 202 may receive a notification from the maintenance operator of the central apparatus 102 that the stepping has not been performed normally. In such a case, the installation operator of the signal controller 202 cannot easily identify where the abnormality has occurred. For example, when the installation worker of the signal controller 202 receives a notification from the maintenance worker of the central apparatus 102 that the step has not been performed normally, the transmission quality between the central apparatus 102 and the signal controller 202 is improved. It cannot be distinguished whether there is an abnormality or whether there is an abnormality in the signal controller 202 itself.

  Further, the signal controller 202 receives signal control command information from the central device 102 until the signal controller 202 receives notification from the maintenance worker of the central device 102 whether or not the stepping has been normally performed. It is not possible to confirm whether or not stepping is being received. That is, the installation operator of the signal controller 202 can know whether or not the step has been performed normally even if the signal controller 202 has not performed the step normally. It is necessary to wait until the central device 102 finishes transmitting the signal control command information.

  Therefore, in the traffic signal control system 802 according to the second embodiment of the present invention, when the step of the signal controller 202 is not normally performed, presentation that supports the identification of the abnormality that has occurred is performed.

[Configuration and basic operation of signal controller]

  The receiving unit 41 receives signal control command information from the central apparatus 102. The receiving unit 41 sends the received signal control command information to the state switching unit 51 and the step determining unit 52. When the signal control command information received from the receiving unit 41 includes a remote command, the state switching unit 51 causes the signal controller 202 to transition to the remote state B, and indicates that the signal controller 202 has transitioned to the remote state B. The state transition notification shown is sent to the state presentation control unit 53, the normal progress presentation control unit 54, and the lamp color switching control unit 55.

  Upon receiving the state transition notification, the state presentation control unit 53 performs control such that the fact that the signal controller 202 has transitioned to the remote state B can be recognized. Specifically, the state presentation control unit 53 receives the state transition notification from the state switching unit 51 and turns on the LED 62.

  In addition, when receiving signal control command information including a step command from the central device 102, the receiving unit 41 sends a step command to the lamp color switching control unit 55. The lamp color switching control unit 55 controls the turning on and off of each signal lamp color in the signal lamp unit 501 in accordance with the step command received from the receiving unit 41.

  Specifically, the lamp color switching control unit 55 proceeds to the next step in response to the step command, and sets the contents of lighting and extinguishing of each signal lamp color for each step in the signal lamp unit 501. The lamp color switching control unit 55 repeatedly executes a cycle composed of a plurality of steps.

  Further, when proceeding to the next step, the lamp color switching control unit 55 sends the floor information indicating the current step of the lamp color switching control unit 55 to the progress determination unit 52, the determination period presentation control unit 57, and the transmission unit 44. . The step determination unit 52 and the determination period presentation control unit 57 can determine that the lamp color switching control unit 55 has shifted to the next step based on the floor information received from the lamp color switching control unit 55. In addition, the transmission unit 44 receives the floor information from the lamp color switching control unit 55, creates confirmation information including the floor information, and sends the confirmation information to the determination period presentation control unit 57.

  Note that the lamp color switching control unit 55 controls lighting and extinction of each signal lamp color in the signal lamp unit 501 in consideration of information from the vehicle detector 601, for example.

  The step determination unit 52 determines whether or not the control by the lamp color switching control unit 55 is normal based on the step command included in the signal control command information. Specifically, the step determination unit 52 determines whether or not the cycle is normally executed by the lamp color switching control unit 55. That is, the progress determination unit 52 determines whether or not the lamp color switching control unit 55 has normally shifted for all the steps included in the cycle.

  For example, the step determination unit 52 determines the number of times that the signal control command information including the step command is received from the receiving unit 41 in one cycle from the first step to the last step, and the floor information from the light color switching control unit 55. The determined number of times the lamp color switching control unit 55 has shifted to the next step is held in the storage unit 58. Then, the step determination unit 52 compares the number of times of receiving the step command stored in the storage unit 58 after one cycle and the number of times the lamp color switching control unit 55 has shifted to the next step. For example, when both coincide, it is determined that the cycle has been executed normally.

  Further, when the step determination unit 52 determines that the cycle has been executed normally, the step execution control unit 54 and the determination period presentation control unit 57 indicate the cycle execution information indicating that the cycle has been executed normally. Send to. In addition, for example, when the signal determination command information including the step command is not received from the reception unit 41 for a predetermined time, the step determination unit 52 performs the lamp color for the predetermined time after receiving the signal control command information including the step command. When the switching control unit 55 does not shift to the next step, or when the number of times the step command has been received is compared with the number of times the lamp color switching control unit 55 has shifted to the next step, the two do not match The cycle failure information indicating that the cycle has not been executed normally is sent to the determination period presentation control unit 57.

  In the normal progress presentation control unit 54, in the remote state B, when the step determination unit 52 determines that the control by the light color switching control unit 55 is normal, the control by the light color switching control unit 55 is normal. Control is performed so that it is possible to recognize the transition to the state determined to be. Specifically, the normal progress presentation control unit 54 turns on the LED 64 when receiving a state transition notification from the state switching unit 51 and receiving cycle execution information from the step determination unit 52.

  The receiving unit 41 receives a step command corresponding to a command to shift to the first step in the cycle, i.e., receives a step command to shift the lamp color switching control unit 55 to the first step. Then, the cycle start command reception information indicating that the step command to shift to the first step has been received is sent to the determination period presentation control unit 57.

  The determination period presentation control unit 57 receives a step command corresponding to the command to shift to the first step in the cycle by the receiving unit 41 or the lamp color switching control unit 55 shifts to the first step. Control is performed so that it is possible to recognize that it is a period until the step determination unit 52 determines whether or not the cycle has been normally executed. Specifically, the determination period presentation control unit 57 receives the cycle start command reception information from the reception unit 41 or receives confirmation information from the transmission unit 44 that can determine that the process has shifted to the top step, and turns the LED 63 on. Light. Then, the determination period presentation control unit 57 receives the cycle execution information or the cycle failure information from the step determination unit 52 and turns off the LED 63.

  Note that the determination period presentation control unit 57 may cause the LED 63 to blink each time a step command is received by the receiving unit 41 or each time the lamp color switching control unit 55 moves to the next step. For example, each time the lamp color switching control unit 55 moves to the next step, if the determination period presentation control unit 57 causes the LED 63 to blink once, the installation operator of the signal controller 202 counts the blinking of the LED 63. Thus, it is possible to recognize how many steps the lamp color switching control unit 55 has shifted to.

  In addition, the reception unit 41 sends the signal control command information received from the central apparatus 102 to the reception presentation control unit 43. The reception presentation control unit 43 receives the signal control command information from the reception unit 41 and performs control so that the reception unit 41 can recognize that the signal control command information has been received. Specifically, the reception presentation control unit 43 receives the signal control command information from the reception unit 41 and turns on the LED 61.

  In addition, the reception unit 41 sends the signal control command information received from the central apparatus 102 to the reception content presentation control unit 42. The reception content presentation control unit 42 receives the signal control command information from the central device 102 and performs control so that the content of the signal control command information can be recognized. Specifically, the received content presentation control unit 42 presents the content of the signal control command information by turning on or off each LED in the LED unit 65.

  The transmission unit 44 transmits confirmation information to the central apparatus 102. Further, the transmission unit 44 sends confirmation information to the transmission content presentation control unit 45. The transmission content presentation control unit 45 receives the confirmation information and performs control so that the content of the confirmation information can be recognized. Specifically, the transmission content presentation control unit 45 presents the content of the confirmation information by turning on or off each LED constituting the LED unit 66.

The “terminal operation” bit is set to “1”, for example, when the signal controller 202 is in the manual operation state. For example, “1” is set in the “operation abnormality” bit when the signal controller 202 has an abnormality or the like.

[Operation]
The signal controller according to the second embodiment of the present invention reads and executes a program including a part or all of each step of the following sequence from a memory (not shown). This program can be installed externally. The installed program is distributed in a state stored in a recording medium, for example.

  FIG. 16 is a diagram illustrating an example of a sequence in which the signal controller according to the second embodiment of the present invention transitions to the remote state B.

  Referring to FIG. 16, first, central apparatus 102 transmits signal control command information including a remote command to communication control unit 302 (step S41).

  Next, the communication control unit 302 receives signal control command information including a remote command from the central apparatus 102, and confirms whether or not the signal control command information includes a remote command (step S42).

  Next, when the communication control unit 302 confirms that the signal control command information includes a remote command, the communication control unit 302 turns on the LED 61 (step S43). If the LED 61 is already lit, the communication control unit 302 continues the lit state.

  On the other hand, if the communication control unit 302 confirms that the signal control command information does not include the remote command, the communication control unit 302 turns off the LED 61 (step S44). If the LED 61 is already turned off, the communication control unit 302 continues the turned off state.

  Next, the communication control unit 302 sends the signal control command information received from the central device 102 to the lamp control unit 402 (step S45).

  Next, the lamp control unit 402 receives the signal control command information and confirms whether or not the signal control command information includes a remote command (step S46).

  Next, when it is confirmed that the signal control command information includes a remote command (YES in step S46), the lamp control unit 402 causes the signal controller 202 to transition to the remote state B (step S47).

  Next, the lamp control unit 402 turns on the LED 62 (step S48). If the LED 62 is already lit, the lamp control unit 402 continues the lit state. Thereby, the lamp control unit 402 presents that the signal controller 202 is in the remote state B.

  Next, the central apparatus 102 transmits signal control command information to the communication control unit 302 (step S49).

  Next, the communication control unit 302 receives the signal control command information from the central device 102, and confirms whether the signal control command information includes a step command (step S50).

  Next, when it is confirmed that the signal control command information includes the step command (YES in Step S50), the communication control unit 302 sends the step command to the lamp control unit 402 (Step S51).

  Next, the communication control unit 302 turns on the LED 63 (step S52). If the LED 63 is already lit, the communication control unit 302 continues the lit state. Thereby, the communication control unit 302 presents a period until it is determined whether or not the cycle has been normally executed.

  Next, the lamp control unit 402 receives the step command sent from the communication control unit 302, shifts to the next step (step S53), and sends the floor information to the communication control unit 302 (step S54).

  Next, the communication control unit 302 receives the floor information from the lamp control unit 402, creates confirmation information, and transmits it to the central device 102 (step S55).

  On the other hand, when it is confirmed that the signal control command information does not include the step command (NO in step S50), the communication control unit 302 sends the signal control command information not including the step command to the lamp control unit 402. (Step S56).

  Next, the communication control unit 302 turns off the LED 63 (step S57). If the LED 63 is already turned off, the communication control unit 302 continues the turned off state. Note that the communication control unit 302 does not receive the signal control command information including the step command from the central device 102 for a predetermined time, or after receiving the signal control command information including the step command from the central device 102, The LED 63 may be extinguished when the floor information that can determine that the process has shifted to the next step is not received from the lamp control unit 402 for a predetermined time.

  Next, the central device 102, the communication control unit 302, and the lamp control unit 402 repeat the operations from step S49 to step S55 until the communication control unit 302 executes, for example, one cycle from the first step to the last step ( Step S58).

  Note that the communication control unit 302 may blink the LED 63 every time the process proceeds to the next step. For example, when the LED 63 is blinked once every time the communication control unit 302 moves to the next step, the installation operator of the signal controller 202 counts the number of steps of the communication control unit 302 by counting the blinking of the LED 63. Can recognize if it has been migrated.

  Next, the communication control unit 302 turns off the LED 63 (step S59). When the LED 63 is already turned off, the turned off state is continued.

  Next, the communication control unit 302 determines whether or not the cycle has been normally executed based on the number of times of receiving the signal control command information including the step command from the central device 102 and the floor information from the lamp control unit 402. Is determined (step S60).

  Next, when the communication control unit 302 determines that the cycle has been executed normally, the communication control unit 302 turns on the LED 64 (step S61). When the LED 64 is already lit, the lit state is continued. Thereby, the communication control unit 302 presents that the cycle has been executed normally.

  On the other hand, if the communication control unit 302 determines that the cycle has not been executed normally, the communication control unit 302 turns off the LED 64 (step S62). If the LED 64 has already been turned off, the communication control unit 302 continues the turned off state.

  On the other hand, when it is confirmed that the signal control command information does not include the remote command (NO in step S46), the lamp control unit 402 causes the signal controller 202 to perform a single operation (step S63).

  Next, the lamp control unit 402 turns off the LED 62 (step S64). When the LED 62 is already turned off, the lamp control unit 402 continues the turned off state.

  FIG. 17 is a diagram illustrating an example of the relationship between the state of each LED and the content of abnormality in the signal controller according to the second embodiment of the present invention.

  For example, when an operator who installs the signal controller 202 receives a notification from the maintenance worker of the central apparatus 102 that the step of the signal controller 202 has not been performed normally, the state of the LEDs 61 to 64 is confirmed. Then, the abnormality content is determined.

  Referring to FIG. 17, when LEDs 61, 62, 63, 64 are off, there is an abnormality between central device 102 and signal controller 202, or signal control command information is not transmitted from central device 102. It can be determined that the signal controller 202 has not received the signal control command information. The abnormality between the central apparatus 102 and the signal controller 202 is a case where normal communication is not performed due to a transmission quality problem between the central apparatus 102 and the signal controller 202, for example.

  Further, when the LED 61 is on and the LEDs 62, 63, and 64 are off, there is an abnormality in information transmission from the communication control unit 302 to the lamp control unit 402, or a remote command is not included in the signal control command information Thus, it can be determined that the signal controller 202 has not transitioned to the remote state B.

  When the LEDs 61 and 62 are on and the LEDs 63 and 64 are off, the signal controller 202 is in the remote state B, but there is an abnormality between the central device 102 and the signal controller 202 or the central device 102. Since the signal control command information including the step command is not transmitted from the signal controller 202, the signal controller 202 can determine that it has not shifted to the first step in the cycle, for example.

  When the LEDs 61, 62, and 63 are on and the LED 64 is off, the signal controller 202 proceeds to the first step in the cycle and proceeds to determine whether the cycle has been executed normally. It can be determined that the process is repeated.

  Further, after the LEDs 61, 62, and 63 are turned on and the LED 64 is turned off, when the LEDs 61 and 62 are turned on again and the LEDs 63 and 64 are turned off, the signal controller 202 is in a remote state. Although it becomes B and it shifted to the first step in the cycle, it can be determined that the determination as to whether or not the cycle has been executed normally has not been made due to an abnormality in the step.

  Further, when the LEDs 61, 62, and 64 are on and the LED 63 is off, the signal controller 202 can determine that the remote state is B and the cycle is normally executed.

  FIG. 18 is a diagram illustrating a relationship between the LED unit and the content of the signal control command information in the signal controller according to the second embodiment of the present invention.

  Referring to FIG. 18, LED unit 65 includes LEDs 71 to 78. The reception content presentation control unit 42 presents the content of the signal control command information received from the central device 102 by turning on or off each of the LEDs 71 to 78.

  Specifically, the received content presentation control unit 42 turns on the LED 71 when receiving the signal control command information in which the “read command” bit 171 is set to “1”, for example. The reception content presentation control unit 42 turns on the LED 72 when receiving the signal control command information in which the “floor keeping” bit 172 is set to “1”, for example. When receiving the signal control command information in which the “remote operation” bit 173 is set to “1”, for example, the reception content presentation control unit 42 turns on the LED 73. The reception content presentation control unit 42 turns on the LED 74 when receiving the signal control command information in which the “stepping” bit 174 is set to “1”, for example. When receiving the signal control command information in which the “sensitive command” bit 175 is set to “1”, for example, the received content presentation control unit 42 turns on the LED 75. When receiving the signal control command information in which the “time adjustment dimming control” bit 176 is set to “1”, for example, the reception content presentation control unit 42 turns on the LED 76. When receiving the signal control command information in which the “presentation switching 1” bit 177 is set to “1”, for example, the reception content presentation control unit 42 turns on the LED 77. When receiving the signal control command information in which the “presentation switching 2” bit 178 is set to “1”, for example, the reception content presentation control unit 42 turns on the LED 78.

  FIG. 19 is a diagram illustrating a relationship between the LED unit and the content of the confirmation information in the signal controller according to the second embodiment of the present invention.

  Referring to FIG. 19, LED unit 66 includes LEDs 81 to 92. The transmission content presentation control unit 45 presents the content of the confirmation information transmitted to the central apparatus 102 by turning on or off each of the LEDs 81 to 92.

  Specifically, the transmission content presentation control unit 45 turns on the LED 81 when transmitting confirmation information in which the “floor confirmation 4” bit 181 is set to “1”, for example. When the transmission content presentation control unit 45 transmits the confirmation information in which the “floor confirmation 3” bit 182 is set to “1”, for example, the LED 82 is turned on. When the transmission content presentation control unit 45 transmits the confirmation information in which the “floor confirmation 2” bit 183 is set to “1”, for example, the LED 83 is turned on. The transmission content presentation control unit 45 turns on the LED 84 when transmitting the confirmation information in which the “floor confirmation 1” bit 184 is set to “1”, for example. When the transmission content presentation control unit 45 transmits the confirmation information in which the “reserved” bit 185 is set to “1”, for example, the LED 85 is turned on. When the transmission content presentation control unit 45 transmits the confirmation information in which the “lamp color 1G” bit 186 is set to “1”, for example, the LED 86 is turned on. When the transmission content presentation control unit 45 transmits the confirmation information in which the “reserved” bit 187 is set to “1”, for example, the LED 87 is turned on. The transmission content presentation control unit 45 turns on the LED 88 when transmitting confirmation information in which the “floor confirmation 5” bit 188 is set to “1”, for example. When the transmission content presentation control unit 45 transmits the confirmation information in which the “present state 2” bit 189 is set to “1”, for example, the LED 89 is turned on. The transmission content presentation control unit 45 turns on the LED 90 when transmitting the confirmation information in which the “present state 1” bit 190 is set to “1”, for example. When the transmission content presentation control unit 45 transmits the confirmation information in which the “terminal operation” bit 191 is set to “1”, for example, the LED 91 is turned on. When the transmission content presentation control unit 45 transmits the confirmation information in which the “operation abnormality” bit 192 is set to “1”, for example, the LED 92 is turned on.

  As described above, in the signal controller 202 according to the second embodiment of the present invention, the receiving unit 41 receives the signal control command information from the central device 102. The state presentation control unit 53 performs control such that it can be recognized that the state has transitioned to the remote state B. In the remote state B, the lamp color switching control unit 55 controls lighting and extinguishing of each signal lamp color in the signal lamp unit 501 in accordance with the step command included in the signal control command information received by the receiving unit 41. The step determination unit 52 determines whether the control by the lamp color switching control unit 55 is normal based on the step command. In the remote state B, the normal step presentation control unit 54 performs control so that it can be recognized that the step determination unit 52 has transitioned to a state in which the control by the lamp color switching control unit 55 has been determined to be normal. Do.

  Thus, for example, the configuration of the signal lamp 501 by the signal controller 202 can be recognized by the configuration capable of recognizing that the signal controller 202 has transitioned to the remote state B and that the display control in the signal lamp 501 is normal. If the central device 102 cannot confirm that the control according to the step command has been normally performed, the signal controller 202 has not transitioned to the remote state B, so that the control has not been performed normally. Even though the controller 202 has transitioned to the remote state B, the control has not been performed normally, or the signal controller 202 has transitioned to the remote state B and the control has been performed normally. Regardless, it can be determined whether the central device 102 has not confirmed. Therefore, it is possible to smoothly perform the operation of setting the signal controller 202 in a state where it can be controlled by the central device 102.

  In the signal controller 202 according to the second embodiment of the present invention, the lamp color switching control unit 55 sets the contents of lighting and extinguishing of each signal lamp color in the signal lamp unit 501 for each step, and a plurality of steps. The cycle consisting of is repeatedly executed. Further, the lamp color switching control unit 55 receives the step command and proceeds to the next step. The step determination unit 52 determines whether or not the lamp color switching control unit 55 has normally shifted for all the steps included in the cycle. The determination period presentation control unit 57 receives a step command corresponding to the command to shift to the first step in the cycle by the receiving unit 41 or the lamp color switching control unit 55 shifts to the first step. Control that makes it possible to recognize that the lamp color switching control unit 55 is in a period until it is determined by the step determination unit 52 whether or not all steps included in the cycle have been normally transferred. I do.

  As described above, the configuration capable of recognizing that the signal controller 202 is in the process until the cycle determination is performed, for example, can recognize that the cycle has not been determined due to the occurrence of an abnormality.

  In the signal controller 202 according to the second embodiment of the present invention, the communication control board 352 includes the receiving unit 41, and the lamp control board 452 includes the lamp color switching control unit 55.

  With such a configuration, for example, when the receiving unit 41 included in the communication control board 352 has an abnormality, the communication control board 352 is removed and replaced while the lamp control board 452 is still mounted on the signal controller 202. And so on. Thereby, even when the communication control board 352 is abnormal, the control of the signal lamp 501 by the lamp control board 452 can be continued.

  In the signal controller 202 according to the second embodiment of the present invention, the signal control command information is received by the receiving unit 41 and sent from the communication control board 352 to the lamp control board 452. When the lamp control board 452 confirms that the remote command is included in the signal control command information sent from the communication control board 352, the status presentation control unit 53 can recognize that the transition to the remote status B has occurred. Control is performed as follows. The reception presentation control unit 43 performs control such that it can be recognized that the signal control command information has been received by the reception unit 41.
