[Problem that the invention seeks to solve]

The conventional distributed train operation management system is configured as described above, so as shown in Figure 8, a single simulator device is installed and a data transmission line is used to connect the central processing unit and each terminal processing unit. It is necessary to exchange data between terminals, and the system cost is high due to the installation of a separate simulator device and the high performance required for the data transmission system, and also regarding the interface in each terminal processing device. In contrast to the parallel interface using the process I/O device during normal operation, the form of the serial interface is different during simulation, and there are many differences depending on the control mode, so it is difficult to realize a simulation that is close to the actual situation. The points were also hot.

This invention has been made to solve the above-mentioned problems, and aims to provide a distributed train operation control system that can simulate conditions closer to reality.

[Means for solving problems]

The distributed train operation management device according to the present invention has each terminal processing device equipped with a simulation logic having functions such as automatic train control device (hereinafter referred to as ATC) route control simulation and train running simulation, and uses an information transmission system. It is designed to enable communication between the central processing unit and each station terminal device.

[Effect]

The distributed train operation management device in this invention includes:
When carrying out a simulation, the operator's simulation start command causes the simulations to start all at once, and by simply transmitting only the previous station departure information to each terminal processing device, it is possible to verify the operation within its own area. System operation verification is possible by transmitting data to the processing device and display panel.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 to 3 and 5 to 8 are the same as the conventional ones. 4b to 4n are terminal processing devices installed at each station. This terminal processing device 4 will be explained with reference to FIG. In Figure 2,
Reference numeral 40 denotes a terminal control management section, which is configured to input a simulation command α and train information β entering the management area, and to output train information β leaving the management area and information γ such as train position detection and route setting. There is. 41 is a simulator function block,
The train running simulator 411 and the ATC route control simulator 412 are configured to be able to exchange signals with each other, and predetermined signals are input from the terminal control management section 40. 42 is a process control unit, which includes a train tracking logic unit 421 that can exchange signals with the terminal control management unit 40, and a route control management unit 422 that is connected to the terminal control management unit 40, respectively.
and a departure command control section 423, and the train tracking logic section 421 and route control logic section 422 are capable of exchanging signals with each other. Reference numeral 43 denotes a control input/output management section, which includes a movable contact c connected to a train tracking logic section 421, a course control logic section 422, and a departure command control section 423, and a simulation contact s connected to an ATC course control simulator 412.
and a contact P through which a process signal δ for a relay interlocking device, information/public relations device, etc. is input/output. In the terminal processing device 4 configured in this way, for example, 4b and 4n in FIG. 1 are adjusted to have a terminal station function, and 4c to 4c are adjusted to have an intermediate station function, respectively.

Next, the operation will be explained. In FIG. 1, when a simulation condition simulating train operation is set in the input setting section of the central processing unit 1 and started, the contact s of the control input/output management section 43 shown in FIG. As shown in FIG. 8, simulation conditions are transmitted from the central processing unit 1 to each of the terminal processing units 4b to 4n via the transmission devices 2a to 2n and the transmission line 3 (step 101). As a result, each terminal processing device 4b to 4n enters the simulation mode,
Train information β and simulation α within each area are collected and transmitted to the central processing unit 1. The central processing unit 1 receives the input train information (step 102)
Based on this, the display panel 8 is driven to display the train position and course setting status (step 103).
As shown at 104, the operations of step 102 and step 103 are repeated until the simulation ends.

Here, the terminal processing devices 4b~ set at each station
The normal operation of the terminal processing device 4n will be explained with reference to FIG. 4, assuming that the monitoring area of the terminal processing device 4b is the range indicated by A in FIG. 5, for example.

The terminal processing device 4b obtains the train position information from the relay interlocking device 5b, performs train tracking as shown in step 105, and confirms the necessity of entry control for the train to enter the station as shown in step 106. . The train enters the monitoring area A shown in Figure 5 and moves from 2T to 3T.
When entering T, it is determined that entrance control is necessary, and the step is to control the course for 6T and 7T.
Run 107. As the train enters the platform track section from inside the station, train tracking is performed in step 108 and train stop detection is performed in step 109. When a train stop is detected, the train schedule and departure time are checked in steps 110 and 111. When the departure time is reached, the train's departure course is controlled in step 112, and then a bell etc. is sounded in step 113. Performs driving departure control. When the train departs in this manner, the train departure information is transmitted to the next adjacent station in step 114, and the train is tracked in step 115.

Next, a case in which a simulation is performed will be explained with reference to FIG. In Fig. 6, step 105~
Step 115 is similar to that shown in FIG. 4, with simulation logic added to the terminal control logic actually used.

Assuming that the stations where the terminal processing devices 4b to 4n shown in FIG. The terminal processing device 4b which received the simulation command from 1 switches the control input/output management unit 43 to the simulation contact S side as shown in step 202. As a result, all subsequent input/output control is in simulator mode, and at the first station, as shown in step 203, a timetable check is performed in step 110, and when the train departure time arrives, terminal processing is performed as shown in step 112. The route control logic unit 422 of the device 4b is operated to output a departure route setting command. This departure course setting command is obtained by simulating the departure course configuration and signal control using the ATC course control simulator shown in step 206c, and inputting the results again into the control.
The departure control shown in step 118 is performed to output a departure signal command, etc., and furthermore, the departure information shown in step 114 is outputted to the adjacent station. Thereafter, as shown in step 205c, the train simulator is operated to simulate the running of the train, and the train is tracked in step 115.

On the other hand, the terminal processing device 4c at the second station receives a simulation command from the central processing device 1 and switches control input/output to the simulator side. In this state, from the time when the previous station departure information in step 204, that is, the departure information from the first station in step 114, is received, train running from the first station is simulated as shown in step 205a.
This simulated train running result is obtained as train speed and train position information with respect to time. Therefore,
This simulation result is used to simulate the acquisition of train detection information using the ATC route control simulator shown in step 206a, and train tracking is performed in step 105. When a simulated train approaches, it is confirmed in step 106 whether or not entry control is necessary, and then in step 107 the route control logic unit 422 is operated to obtain a command to set an entry route. This command is used to construct interlocking simulation logic in the ATC course control simulator in step 206b, and further to simulate train running in step 205b. Thereafter, in steps 108 and 109, train tracking and stoppage detection are performed. Note that the control logic for departing from the second station is the same as the logic shown in steps 110 to 115 described for departing from the first station, so a description thereof will be omitted. Departure information obtained at the second station is sent to an adjacent third station.

In this way, the first
The train departure information for the station is sent to the second station and the train departure information for the first station is sent to the second station.
The train simulator between the station and the second station is operated, and the train departure information at the second station is sent to the third station, and the train simulator between the second station and the third station is operated. Therefore, information propagation and simulator operation are performed at the first station, second station, and third station.

FIG. 7 shows a simulator function block 41a according to another embodiment, which is similar to that of FIG. 2 except that a passenger model simulator 413 is connected to a train running simulator 111. By using this simulator function block 41a, control similar to the actual process of the train operation management system is possible, and it is also possible to verify the natural occurrence of train delays and the rescheduling of trains in response to the occurrence of delays.

Note that the train running simulator in the above embodiment may have common logic for each terminal processing device, and the ATC
Route control simulators differ depending on the station where the terminal processing device is installed, but the simulator logic is common to each terminal processing device, and programs can be designed so that only the data structure is different.

〔Effect of the invention〕

As described above, according to the present invention, simulated logic is incorporated into each of a plurality of terminal processing devices, so daily maintenance and inspection can be performed without actually running the train, and the system operation can be completed quickly. Functional verification can be performed.
