Description

  The present invention relates to a station-distributed operation management system in which a central device that manages the operation of a train and a station control device that controls the operation of a train are connected via a communication network, and in particular, between the station control device and the central device. Related to the operation mode management.

  In general, a train operation management system that manages the operation of a train shows track circuit information indicating whether or not the train is on each track circuit (track section) corresponding to the track of the train, and indicates the state of each traffic signal. Incorporate current information, train direction, etc. from the interlocking device, refer to the train schedule information, create tracking information about which train is running in what state, and to the operation management operator Provide information. At the same time, the train operation management system determines the route of each train from the tracking information and a predetermined train schedule, creates route control information, sends it to the interlocking device, and sends signals and switches to the interlocking device. By performing the control, the actual train path is controlled.

  On the other hand, the train operation management system is used when facilities such as the track circuit and signal equipment of the station are updated or new functions are added for better operation management while performing the daily operation described above. The computer program and data will be improved. At this time, it is necessary to confirm whether the modified software functions normally. Conventionally, a simulator is used for the confirmation test, and the train operation is simulated based on the train schedule, and the quality of the repair has been confirmed by the simulation result. In the “simulation” mode, the linkage information is created in a simulated manner, and the train operation management system operates the program used in the “operation” mode by using this, and the route control information is simulated and output. The course control simulation output is merely a pseudo output inside the computer and is not output to an external interlocking device.

  As such a train operation management system, for example, as shown in Patent Document 1, an operation management central device installed at a central command office of a railway company, etc., and a simulation of each train operation management device installed at each station There has been proposed one that can be controlled in synchronization with the operating state and can perform detailed simulation over a wide range.

  FIG. 7 is a block diagram showing a conventional train operation management system. Two station control devices 31a and 31b having the same specifications are installed at each station on the railway company. 31a and 31b perform a so-called hot stand-by dual system operation, one of which performs control output is the main system, and the other which is waiting for control is the sub system. Each station control device 31a, 31b of each station is connected to two operation management central devices 33a, 33b installed in a central headquarters etc. via a communication network 32 such as a LAN. The operation management central devices 33a and 33b are also required to have high reliability for continuous operation. For this reason, the hot stand-by dual system operation is performed in the same manner as the station control device, the information system is provided to the man-machine device for operation management indicated by 34, and the other system waiting for information output is the slave system. . A simulation man-machine device 35 is connected to the slave operation management central device 33b.

The station control device 31 (hereinafter referred to simply as “31” when the main system 31a and the subordinate system 31b are collectively referred to simply as the “station control device”) is provided at each station. Train tracking and route control for each train operating in the vicinity. Then, the result is sent to the operation management central device 33 via the communication network 32 and displayed on the operation management man-machine device 34.
In addition, in this train operation management system, two types of operation modes of “operation” mode using this train operation management system as a normal operation management device and “simulation” mode using as a simulation device are provided, It can be controlled by the system operator.

  When the operation mode is set to “operation”, the station control device creates tracking information of the train using the linkage information input from the linkage device at regular intervals, and sends it to the central device. The central device that has obtained the information collects the information sent from the station control devices of all the stations it manages and constantly displays and outputs it to the man-machine device for operation management. Further, the station control device determines the route of each train from the result of the train tracking to control the train route and the train schedule, creates route control information, and sends it to the interlocking device.

  On the other hand, when performing software maintenance, the operation mode is set to “simulation”. In this case, the station control device generates simulated interlocking information from the built-in simulator at regular intervals, tracks the train using this information, sends it to the central device, and collects information from each station control device at the central device. After that, it is displayed on the man-machine device for operation management. Further, the station control device determines the route of each train from the tracking information based on the simulation result and the train schedule, creates route control information, and sends it to a built-in simulator that simulates the movement of the interlocking device.

JP 2000-016295 A

  In the station-distributed operation management system as described above, the operation check test of the operation management system sets the operation mode to "simulation", while communicating between the operation management central device and the station control device via the communication network, A simulator was used to simulate train travel and create linkage information. In such an operation management system, the communication procedure between the operation management central device and the station control device is the same, so that the system operating in the operation system and the system operating in the test system receive and process communication messages equally. It was.

  Therefore, even if the function that the application identifies and does not process the test message is incorporated, the message reaches the application layer, which increases the operational computer load and increases the processing time of the operational system. As a result, the test could not be carried out while the operation system and the test system coexisted. For this reason, software maintenance was performed within a few hours from the end of the last train to the start of tracking the first train, and during that time, updating to new software, confirmation tests, and restoration to existing software were performed, which was very inefficient.

  The present invention has been made to solve the above-described problems. One system of the operation management central device and the station control device, which is a dual system operation, is an operation system, and the other is a test system. It is an object of the present invention to provide a station-distributed operation management system that enables maintenance work to be performed at any time, and enables efficient system maintenance work.

The station-distributed operation management system according to the present invention is divided into a main system and a subordinate system, and a central system that performs dual system operation and supervises the operation of a train, and a main system and a subordinate system are divided into a dual system. In a station distributed operation management system comprising a plurality of station control devices that operate and perform train tracking and route control, and a communication network that connects these to communicate diamond information and train control information, the main system Communication ports that can be set by distinguishing between the "simulation" mode for performing a pseudo-confirmation test and the "operation" mode for performing a normal operation. In normal operation, all communication ports are set to "operation" mode.
When the confirmation test is performed between the slave systems, the communication ports between the master systems are set in the “operation” mode, and the communication ports between the slave systems are set in the “simulation” mode.

  According to the station-distributed operation management system of the present invention, a “simulation” is performed in which a verification test is performed on each communication port of the master and slave central processing units and each of the master and slave station control devices in a pseudo manner. ”Mode and“ operation ”mode that performs normal operation can be set separately, so that all communication ports are set to“ operation ”mode during normal operation, and communication between main systems is performed when a confirmation test is performed between slaves. Because the ports are set to "operation" mode and the communication ports of the slaves are set to "simulation" mode, one system of the operation management central unit and station control system, which are dual operation, is operated, and the other is tested. As a system, system maintenance work can be performed at any time, and efficient system maintenance work can be performed.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of a station distributed operation management system according to Embodiment 1 of the present invention. Parts corresponding to those in FIG. 7 are denoted by the same reference numerals, and a part of the description is omitted. The station-distributed train operation management system according to the first embodiment operates a train, and provides the train line status, signal display status, and the like from each station control device 31 to the operation management central device 33 via the communication network 32. . In addition, the station distributed train operation management system displays the train line status, signal display status, etc. on the station control device 31 of each station having a train operation simulation function and the operation management man-machine device 34 for operation management. It is comprised with the operation management central apparatus 33 which provides the control operation input in the man-machine apparatus 34 to the station control apparatus 31 via the communication network 32 as control information.

  Communication between the operation management central device 33 and the station control device 31 via the communication network 32 is performed by broadcast communication, and an application determines necessary information. Similarly to FIG. 7, the operation management central unit 33 and the station control unit 31 are each composed of two computers, and normally perform a so-called hot stand-by dual system operation. One of the control outputs is operated as a main system, and the other waiting for control is operated as a sub system. A simulation man-machine device 35 is connected to the secondary operation management central device 33b.

  In such a station-distributed operation management system that performs dual system operation, communication ports of the main and subordinate central processing units 33a and 33b and the main and subordinate station control devices 31a and 31b are provided. For example, the operation management central device 33b and the station control device slave 31b can be set in the “simulation” mode by making it possible to distinguish and set the “simulation” mode for performing a pseudo confirmation test and the “operation” mode for performing normal operation. By setting and opening test communication ports that are different from those used for operation and closing (non-setting) the operation communication ports for those communication ports, the operation management central unit operating in the “operation” mode Since the test communication port is closed between the system 33a and the station controller main system 31a even if the message format and communication protocol are the same, Never running management central unit 33b and the station controller slave 31b operating in Interview configuration "mode receives a message to be transmitted.

  On the contrary, the message between the operation management central device main system 33a and the station control device main system 31a is not received because the operation communication port is closed in the operation management central device 33b and the station control device sub system 31b. The operation management central device main system 33a and the station control device main system 31a operating in the mode, and the operation management central device 33b and the station control device 31b operating in the “simulation” mode can be operated simultaneously without interfering with each other. .

  Note that enabling communication ports to be set separately in "simulation" mode and "operation" mode means that the computer is opened in distinction between when operating in "operation" mode and when operating in "simulation" mode. By making it possible to set a communication port, a communication port managed by the OS to be opened (enabled) or closed (disabled) is set. When performing network communication between computers, a header indicating which message is transmitted to which communication port of which IP address is added. When the computer is turned on and started up, the OS refers to a definition file indicating which communication port is opened (enabled) and opens the communication port. When a message addressed to an opened communication port arrives, the message can be received, but a message addressed to a closed (invalid) communication port cannot be received.

  Therefore, by making the “operation” communication port and the “simulation” communication port completely different, a computer operating in the operation mode and a computer operating in the “simulation” mode cannot communicate (the network is physically connected). However, since the communication ports are different, logical communication is not possible. At this time, computers operating in the “operation” mode (or “simulation” mode) can communicate with each other. Therefore, communication is possible if the central device slave and the station controller slave are operating in the same mode.

FIG. 2 is a block diagram showing the configuration of a station distributed operation management system according to Embodiment 2 of the present invention. The same code | symbol is attached | subjected to the same or equivalent part as the station dispersion | distribution type operation management system which concerns on Embodiment 1 shown in FIG. Therefore, the detailed description of the overlapping part is omitted.
In the station-distributed operation management system according to the second embodiment, a system management terminal that can monitor the operation state of the entire operation management system and stop the operation state (operation mode) of each device or start operation. 36. The person in charge of system operation communicates from the central command office after switching the operation management central device 33b and the station control device slave 31b of the dual system configuration to the stopped state from the system management terminal 36 installed in the central command center. The operation mode of the operation management central device 33b and the station control device 31b is instructed to be switched to “simulation” via the network 32. The operation management central device 33b and the station control device 31b instructed to switch the test can automatically change the operation mode according to the given operation mode according to the flowchart shown in FIG.

  The operation steps will be described according to the flowchart shown in FIG. In step S1, the operation management central device 33b and the station control device 31b are rebooted. After rebooting, at the time of startup, the operating system (OS) refers to the communication port definition file and opens the test communication port according to the communication port definition file at step S2. After the communication port definition file is updated to the operation communication port definition file in step S3 (in preparation for the next time), the operation state is changed to step S4. At this time, if the open communication port is a test communication port, the operation management central device 33b and the station control device 31b have started up in the “simulation” mode, and the operation management central device 33a started up in the operation system. The message transmitted from the station control device 31a is not received because the communication port to be received is different, and the operation management central device 33a and the station control device 31a are opened from the operation management central device 33b and the station control device 31b. Messages are not sent to the operational communication port.

  Further, after the operation management central device 33b and the station control device subordinate 31b having a dual system configuration are changed from the system management terminal 36 of the central control center to the stop state via the communication network 32, the operation management central device 33b and When instructing to switch the operation mode of the station control device 31b to “operation”, the operation management central device 33b and the station control device 31b set “test” and “operation” as “test” shown in the flowchart of FIG. And read and operate.

  That is, the operation management central device 33b and the station control device 31b are rebooted in step S1. After rebooting, at the time of startup, the operating system (OS) refers to the communication port definition file and opens the operation communication port according to the communication port definition file at step S2. In step S3, the communication port definition file is updated to the test communication port definition file (in preparation for the next time), and then the operation state is changed in step S4. At this time, since the main system of the operation management central device 33a and the station control device 31a has been set up with the operation mode “operation”, the operation management central device 33b and the slave system of the station control device 31b are connected to the operation management central device 33a and The same message as the station control device 31a is received and the same processing is performed, but since it is in a standby state, the message is not transmitted according to the definition of the dual system operation.

Embodiment 3 FIG.
FIG. 4 is a block diagram showing the configuration of a station distributed operation management system according to Embodiment 3 of the present invention. The same code | symbol is attached | subjected to the same or equivalent part as the station dispersion | distribution type operation management system which concerns on Embodiment 2 shown in FIG. Therefore, the detailed description of the overlapping part is omitted. In the station distributed operation management system according to the third embodiment, the central processing devices 33a and 33b and the station control devices 31a and 31b are each provided with an “operation mode definition file” representing an operation mode currently being operated. This “operation mode definition file” holds the operation mode until the operation mode reaches “operation” or “simulation” by the mode change input given from the system management terminal 36. With this "operation mode definition file", if the operation mode before shutdown is "operation", the power is turned on and the system automatically starts up to "master" or "secondary" operation, and if the operation mode before shutdown is "simulation" In particular, it will rise up to “test” operation and allow any operation mode configuration according to the given operation mode.

  If you want to switch the operation mode of the secondary system to "Simulation" while the operation mode of the primary system and the secondary system is "Operation" in a dual system configuration, the system operator is a system installed at the Central Command Center. After switching the operation management central device 33b and the station control device slave 31b of the dual system configuration from the management terminal 36 via the communication network 32 to the stopped state, the system management terminal 36 of the central headquarters via the communication network 32 The operation mode of the operation management central device 33b and the station control device 31b is instructed to switch to “simulation”.

  The operation management central device 33b and the station control device 31b instructed to switch the test are automatically operated until the “main system” or “secondary” operation when the power is turned on because the operation mode held before the shutdown is “operation”. Get up. According to the flowchart shown in FIG. 5, step S11 is YES, the communication port definition file is updated to the test communication port definition file in step S12, and the operation management central device 33b and the station control device 31b are rebooted in step S13. After rebooting, at startup, the operating system (OS) refers to the communication port definition file in step S14. If the test communication port definition is in accordance with the communication port definition file, the test communication port is opened in step S15. Next, when the application is activated, the operation mode file is updated to the currently activated operation mode in step S16, and the operation state is changed in step S17.

  At this time, since the opened communication port is a test communication port, the operation management central device 33b and the station control device 31b are started in the “simulation” mode, and the operation management central device 33a started in the operation system. The message transmitted from the station control device 31a is not received because the communication port to be received is different, and the operation management central device 33a and the station control device 31a are open from the operation management central device 33b and the station control device 33b. Do not send messages to the port.

  Similarly, if you want to switch the operation mode of the secondary system to “operation” while operating in the dual system configuration with the operation mode of the master system being “operation” and the operation mode of the slave system being “simulation”, system operation The person in charge changes the operation management central unit 33b and the station control unit subordinate 31b of the dual system configuration from the system management terminal 36 installed in the central command center to the stop state via the communication network 32, and then the central commander The operation management central device 33b and the station control device 31b are instructed to switch to “operation” from the system management terminal 36 via the communication network 32.

  The operation management central device 33b and the station control device 31b instructed to switch the test automatically start up to the “simulation” operation when the power is turned on because the operation mode held before the shutdown is “simulation”. According to the flowchart shown in FIG. 5, step S11 is NO, the communication port definition file is updated to the operation communication port definition file in step S12 ′, and the operation management central device 33b and the station control device 31b are rebooted in step S13. . After rebooting, at startup, the operating system (OS) refers to the communication port definition file in step S14, and if the operation communication port definition is in accordance with the communication port definition file, the operation communication port is opened in step S15 ′. . Next, when the application is activated, the operation mode file is updated to the currently activated operation mode in step S16, and the operation state is changed in step S17.

  In this way, if the operation mode before shutdown is "operation", the power is turned on and startup is started in "primary" or "secondary" operation, and if the operation mode before shutdown is "simulation", it is started in "test" operation. In other words, the operation mode can be switched by bringing the operation mode to “operation” or “simulation” by the mode change input given from the system management terminal 36.

Embodiment 4 FIG.
In the station-distributed operation management system according to the fourth embodiment, the operation control / display includes a switch for operation control of the system and a lamp for displaying an operation state and an operation mode in the operation management central device 33 and the station control device 31. A panel (CIP) is provided so that the system operator can directly perform a mode switching operation or confirm the operation state and operation mode in front of each computer (operation management central device 33 and station control device 31). Is.

  FIG. 6 is an outline view showing an operation control / display panel (CIP) provided in the operation management central device 33 and the station control device 31 of the station distributed operation management system according to the fourth embodiment. The operation control / display panel includes an operation state display unit and an operation unit for each system. In addition, the I system and the II system indicate that they are dual systems, and one corresponds to the main system and the other corresponds to the sub system. The operation state display section is stopped (for example, in the I system), a main operation lamp 11 that is turned on when the main operation is in progress, a slave operation lamp 12 that is turned on when the operation is in progress, and a stop. A stop lamp 13 that is lit in the case, a test operation lamp 14 that is lit when the test operation is being performed, and an operation lamp (operation mode display lamp) 15 that is lit when the operation mode is “operation”.

  The driving operation unit includes a driving operation button 21 for changing the system to the operating state, a stopping operation button 22 for changing the system to the stopped state, and a system switching operation button for switching the operating state of the main system and the slave system during the dual system operation. 23, a key switch 24 that switches between an operation mode and a maintenance mode by inserting a key, and an operation control switch including a mode switching operation switch 25 that switches an operation mode between “operation” and “simulation”. The system operator can directly perform a mode switching operation on the operation unit while confirming the operation state of the system on the operation state display unit on the operation control / display panel.

  Here, if the key switch 24 is on the operation side, the driving operation button 21 and the stop operation button 22 can be operated. If the key switch 24 is on the maintenance side, the mode switching operation button 25 can be operated. If the key is set to the maintenance side and the operation mode is "Simulation", the system automatically transitions to the "Test" operating state when the system starts up. Only transitions. Next, if the key is set to the operation side and the operation mode is `` operation '', the system automatically transitions to the `` primary '' or `` secondary '' operation state when the system starts up, but the operation mode is `` simulation '' If there is, it will only transition to the “stop” state. For this reason, it is possible to prevent the system operator from switching to the test mode during operation or entering the operation state during the test due to an erroneous operation by the system operator.

  The operation in the case where the operation management central device 33b and the station control device 31b, which are operating as the slaves of the dual system constituent devices, are transitioned to the “simulation” mode will be described. For example, in the II system, the operation management central device 33b and the station control device 31b have the operation mode of “operation” and are in the slave operation, so the operation state display section of the operation control / display panel is the slave operation lamp 12b. The operation lamp 15b is lit. When the key switch 24b is operated to the maintenance side on the operation / display panel of the operation management central device 33b and the station control device 31b, the operation management central device 33b and the station control device 31b transition from the secondary operation state to the stop state. . At this time, the secondary operation lamp 12b is turned off and the stop lamp 13b is turned on. When the mode switching operation button 25b on the operation control / display panel is pressed here, the operation mode of the operation management central device 33b and the station control device 31b is changed from “operation” to “simulation” according to the operation of the third embodiment.

  That is, if the operation mode is “operation” in step S11 of the flowchart of FIG. 5, the communication port definition file is updated to the test port definition in step S12, and the computer is rebooted in step S13. After the rise, since the communication port definition file is a test port definition in step S14, the test communication port is opened in step S15, and the operation mode definition file is updated to the “simulation” mode in step S16. At this time, since the operation mode file is the “simulation” mode, the operation lamp 15b of the operation / display panel is turned off, and when the operation state is changed to the operation state in step S17, the operation state is automatically changed to the “test” operation state. The stop lamp 13b is turned off and the test operation lamp 14b is turned on.

  When the mode switching operation button 25b is pressed after the test is completed, since the operation mode is “simulation” in step S11 of FIG. 5, the communication port definition file is updated to the operational port definition in step S12 ′, and step S13. Reboot the computer with. After the rise, since the communication port definition file is the operation port definition in step S14, the operation communication port is opened in step S15 ', and the operation mode definition file is updated to the "operation" mode in step S16. At this time, since the operation mode file is the “operation” mode, the operation lamp 15b of the operation control / display panel is turned on, and when the operation state is changed to the operation state in step S17, the partner system is normally operating in the main system. Therefore, the system automatically transitions to the slave operation state, but since the key switch 24b is set to the maintenance side, the system transitions only to the stop state, and the test operation lamp 14b of the operation control / display panel is turned off. The stop lamp 13b is turned on. The system operator confirms that the stop lamp 13b and the operation lamp 15b of the operation control / display panel are lit, operates the key switch 24b to the operation side, and then presses the operation button 21b to cause the system to operate as a slave operation. Transition to the state. Therefore, the stop lamp 13b is turned off and the slave operation lamp 12b is turned on.

  This invention makes it possible to carry out system maintenance work at any time and at any time, making one system of the operation management central device and the station control device, which is a dual system operation, an operation system and the other system a test system. System maintenance work can be performed, and it is suitable for application to a train operation management system.
