Abstract

PURPOSE:To provide a system for controlling train operation even when a station controller fails in a train operation management system, for which a central processing unit for integrating and controlling the operation manage ment of trains is connected with the station controller provided at each station, for controlling the operation of trains, by a transmission route. CONSTITUTION:A preliminary controller 15 is connected to a transmission route 7 through a station communication device 14. When a station controller 8A fails, the failure occurrence is alarmed by a station communication device 11A. When this alarm is passed on to the preliminary controller 15 through the station communication device 14, train tracking information is formed by the preliminary controller 15, and is transmitted to a central processing unit 1a.

In the figure, 1a and 1b are central processing units that collect the train operation statuses of all stations, monitor the trains and create operation records, and centrally manage the train operation. Is bound to.

3a and 3b are operation panels for inputting timetable change information and the like to the central processing units 1a and 1b, 4a and 4b are character displays for operation input, and 5 is an operation display for displaying train operation status. The panels 6a and 6b are central communication devices that are interposed between the central processing units 1a and 1b and the transmission path 7 to exchange signals such as operation information. 8A, 8B, and 8C are station control devices that are provided for each station under jurisdiction and that control train operations, and take in station equipment information such as track circuits 9, traffic lights (not shown), and switches (not shown). The relay interlocking devices 10A, 10B, 10C are respectively connected. 11A, 11B and 11C are station communication devices which are interposed between the station control devices 8A, 8B and 8C and the transmission line 7 to exchange signals such as operation information. S1 to S6 are stations, and T1 and T2 are trains in operation. 12A, 12B, 12C and 13A, 13B, 13
C indicates a sensor and a station communication device which are connected in parallel with the station control devices 8A, 8B and 8C.

Next, the operation of the conventional system will be described with reference to FIG. Station control device 8A relays train position information to relay interlocking device 10
Train tracking information corresponding to the train is created via A, and transmitted to the central processing unit 1a via the station communication device 11A, the transmission path 7, and the central communication device 6a. Similarly, the station control device 8B fetches train position information via the relay interlocking device 10B, and the station control device 8C fetches train position information via the relay interlocking device 10C and transmits it to the central processing unit 1a. The central processing unit 1a displays the operation status of the train based on the sent train tracking information.
To display. For example, if the station control device 8A fails and the processing function is stopped, the information from the relay interlocking device 10A will not be transmitted to the central processing unit 1a. Therefore, the central processing unit 1a sends and receives train position information via the sensor 12A and the station communication device 13A, simulates train operation, and displays the content on the operation display panel 5.

[0005]

Since the conventional train operation management system is configured as described above, the station control device
When 8A or the like fails, the central processing unit 1a can send and receive train position information via the sensor 12A and station communication device 13A to simulate train operation, but there is a problem that train operation control cannot be performed. It was

The present invention has been made to solve the above problems, and it is an object of the present invention to provide a train operation management system capable of controlling the operation of a train even when the station controller fails. To aim.

[0007]

A train operation management system according to the present invention comprises a central processing unit for integrally managing train operation,
In a distributed train operation management system in which a station control device that is installed in each station and that controls train operation by capturing train position information is connected by a transmission line, in the case where the station control device fails, a signal that reports the failure is sent. It is characterized by comprising means for outputting to the transmission line, and a standby control device which is connected to the transmission line and receives the signal and monitors and controls the operation of the train.

[0008]

When the station control device fails, the standby control device according to the present invention takes in information in the range covered by the failed station control device and exchanges information with the central processing unit.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing the embodiments thereof. In Fig. 1, 1a and 1b are central processing units that collect the train operation status of all stations, monitor the trains and create operation records, and centrally manage the train operation. Are connected to each other.
3a and 3b are operation panels for inputting time change information and the like to the central processing units 1a and 1b, 4a and 4b are character displays for operation input, 5 is an operation display panel for displaying train operation status, and 6a , 6b are central communication devices that are interposed between the central processing units 1a, 1b and the transmission path 7 and exchange signals such as operation information.

In addition to this, the system of the present invention is provided with a standby control device 15 on the center side and is connected to the transmission line 7 via a station communication device 14. 8A, 8B, and 8C are station control devices that are provided for each station under its control and that control the operation of trains, and take in station equipment information such as track circuits 9, traffic lights (not shown), and switchers (not shown). Relay interlocking devices 10A, 10B, 10C are connected respectively. 11A, 11B and 11C are station communication devices which are installed between the station control devices 8A, 8B and 8C and the parallel sensors 12A, 12B and 12C and the transmission line 7 to exchange signals such as operation information. . S1 ~
S6 is a station and T1 and T2 are trains in operation.

Next, the operation of the system of the present invention will be described. When all the station control devices 8A, 8B, 8C are operating normally, the operation is the same as the normal operation of the conventional system. For example, if the station control device 8A fails and the processing function is stopped, the information from the relay interlocking device 10A will not be transmitted to the central processing unit 1a.

Therefore, when the station communication device 11A detects a failure of the station control device 8A, the train position information is transmitted to the standby control device 15 via the transmission path 7 and the station communication device 14 via the sensor 12A. The standby control device 15 creates train tracking information corresponding to the train based on the train position information and transmits it to the central processing unit 1a via the station communication device 14, the transmission line 7, and the central communication device 6a. In addition, the standby control device 15 includes the station communication device 14, the transmission line 7,
It outputs the route setting to the relay interlocking device 10A via the station communication device 11A and the sensor 12A.

[0013]

As described above, according to the present invention, since the station control device is switched to the standby control device when a failure occurs, reliability of train operation monitoring and train operation control can be continuously performed even when a failure occurs. A highly efficient system can be realized.
