Abstract

PURPOSE:To improve service and reliability by eliminating a possibility of preventing a train from running at a station even when the machine at the station fails, through a distributed total traffic control system. CONSTITUTION:Normally, the train route in a station is automatically managed and controlled by the train route control processing part 17 of a station controller 12 based on the total traffic diagram managed by a central unit 11. When abnormally happens and no total traffic diagram becomes available, the train route at the station is controlled by a manual route control processing part 18 by means of manual interference from the central unit 11. The distributed management of total traffic is carried out under normal conditions while the train route at each station is continuously managed by means of manual interference even when the station controller 12 fails, so as to minimize degradation of service and to improve the reliability of total traffic.

It is equipped with a train route control processing unit 4 that determines the route direction of each train based on the train schedule assigned by 3 and controls the train route, and a manual route control processing unit 5 that controls the train route by manual intervention. Each station is provided with an interlocking device 6 that controls switching between points and signals by means of a signal from the central device 1 and guides station broadcasting, and is connected to the central device 1 by a LAN or other transmission device 7.

However, in such a conventional centralized train operation management system, when an abnormality or failure occurs somewhere in the central unit 1 and the machine goes down, the operation of all trains in the section managed by the central unit 1 is performed. However, there was a problem that it caused a great deal of confusion.

Therefore, in recent years, in order to minimize the influence of such a machine down of the central unit 1, the control units are distributed to each main station unit, and the train operation management for each station is performed by the station control unit. Type train operation management system is being adopted.

This decentralized train operation management system is designed so that even if a station control device goes down, only that station becomes inoperable and other stations can operate normally. However, even in the conventional distributed train operation management system, there is still a problem that the train operation is disabled until the machine down occurs in the station where the station control device has a machine down, and the service deteriorates.

[0006]

As described above, in the conventional centralized train operation management system, when the central unit goes down, it is impossible to operate all the trains in the section managed by the central unit. There was a problem that caused a lot of confusion.

Further, even in the conventional distributed train operation management system, there is still a problem that the train operation cannot be performed and the service is deteriorated at the station where the station controller has a machine down, until the machine down is resolved.

The present invention has been made in view of the above-mentioned conventional problems, and even if a machine down occurs in any station control device, the train operation is continuously continued by manual intervention, and the deterioration of service is minimized. The objective is to provide a train operation management system that can be held to the limit.

[0009]

According to the present invention, there is provided a train operation management system in which a central device and a station control device installed at each main station are connected by a communication line to enable mutual communication. In addition, the train schedule management unit that sequentially registers train schedules is provided, and the station control device includes a train position detection processing unit that detects a train position and a train position management unit that manages the train position detected by the train position detection processing unit. Based on the train track processing unit that allocates the train timetable to the train whose position is detected by collating it with the train operation timetable from the department, based on the train timetable allocated by the train tracking process unit, the direction of travel of the position-detected train And a train route control processing unit that controls the train route, and a manual route control processing unit that controls the train route by manual intervention from the central unit.

[0010]

In the train operation management system of the present invention, normally, the train path control processing unit of each station control device automatically manages and controls the train path of its own station based on the train operation diagram managed by the central unit. When an abnormality occurs and the train operation schedule disappears, the manual route control processing unit controls the train route of the own station by manual intervention from the central unit.

In this way, the decentralized management of the train operation at normal times is performed, and even if one of the station control devices goes down, the train route of the corresponding station is continuously managed by manual intervention, and the deterioration of service is suppressed as much as possible. , Improve the reliability of train operation.
