Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operation management system for managing the operation of transportation facilities such as trains, buses, ships, and airplanes.

[Conventional technology]

FIG. 2 is a block diagram showing the configuration of a train traffic management system that employs, for example, a conventional traffic management system. In the figure, 1 is a central management computer that instructs the operation of transportation facilities according to registered timetable data, and 2 is a control computer included in the timetable data registered in the central management computer 1.
3 is a relay interlocking device for controlling train points, signals, etc. and knowing the status of track circuits; 4 is a display that provides train guidance to passengers; 5 is a guide broadcasting device that provides train guidance to passengers by voice; 6 is a track circuit device that identifies the position of the train; 7 is a point that determines the course of the train; and 8 is a signal.

Further, R is the track (operating route) on which the train runs, and S is the station.

Next, the operation will be explained. In the central management computer 1, timetable data for instructing train operations is manually registered, and this timetable data consists of train numbers for identifying train operations, arrival times and departure times for each station. ing.゛At the relevant time, the central pipe operating computer 1 uses the relay interlocking device 3 via the transmission device 2 to confirm the train position. At this time, the relay interlocking device 3 learns of the change in the state of the track circuit 6 and transmits this to the central management computer 1. When the central management computer 1 learns of the approach of a train, it provides output information to the destination display 4 and the guidance broadcasting device 5 based on the timetable data.

Next, when the train is to depart, when the central management computer 1 determines that the departure time indicated by the timetable data has arrived, it transmits a relay signal based on the timetable data. Since the trains are operated in sequence in this way, each device must be controlled using the schedule data held by the central control computer, and the information held by the relay interlocking device is transmitted in real time. It is necessary to send and receive the information through the transmission line (transmission equipment), and if a failure of the central management computer or failure of the transmission line occurs, control on the entire line is immediately interrupted until the failure or failure is recovered. Each device must be controlled manually, which poses problems such as difficulty in securing maintenance and operation personnel.

This invention was made to solve the above-mentioned problems, and by providing a computer for dividing operation management that controls operation based on timetable data etc. distributed over divided operation routes (stations or station groups), The objective is to create an operation management system that can minimize the impact on the entire line due to failures in the central management computer or failures in transmission lines, and minimize the need for maintenance and operation personnel.

[Means to solve the problem]

In the traffic management system according to the present invention, a divided traffic management computer (station control computer 9) is installed in correspondence with each divided traffic route in which the traffic route (track R) is divided into a plurality of sections in advance. A plurality of computers are arranged in a wide area, and these divided operation management computers control the operation of transportation facilities on the divided operation routes for which they are in charge using decentralized timetable data based on the timetable data in the central management computer 1. This is a characteristic feature.

[Effect]

The central management computer 1 decentralizes the registered timetable data so that each divisional operation management computer can instruct the transportation facilities on each divisional operation route, and sends the registered timetable data to each divisional operation management computer. Transmit each. Therefore, each divided operation management computer registers the decentralized timetable data, and controls the operation of each transportation facility on the divided operation route in accordance with this data.

[Embodiments of the invention]

FIG. 1 is a block diagram showing the configuration of a train traffic management system that employs a traffic management system according to an embodiment of the present invention. In FIG. 1, components corresponding to those shown in FIG. 2 are given the same reference numerals, and their explanations will be omitted. In Fig. 1, reference numeral 9 denotes a station control electronic computer (divided operation management computer) that controls the operation of the transportation facilities on the divisional service routes it is in charge of using decentralized timetable data based on the timetable data in the central management computer 1. 10 is a device 2 for transmitting decentralized timetable data to a station control computer 9, etc.
A distributed database master station 11 is provided in the central management computer 1 to transmit distributed timetable data transmitted from the distributed database master station 10 provided in the station control computer 9. This is a distributed database slave station to be registered. A plurality of station control computers 9 are arranged in a wide area corresponding to stations S or station groups (divided operating routes) in which the train (transportation) track (operating route) R is divided into a plurality of sections in advance. .

Next, the operation will be explained. In the central management computer 1, timetable data for instructing train operation is manually registered, but this timetable data is divided into stations S or station groups so that it can be easily managed by the station control computer 9. This transmitted data is registered in the distributed database slave station 11 and constructed on the station control computer 9 as distributed timetable data. The station control computer 9 monitors the status of the track circuit 6 via the relay interlock device 3 based on the day's timetable, and when it detects that a train is approaching, the station control computer 9 updates the distributed database child. The timetable data is extracted from the station 11 and output information is provided to the destination display 4 and the guidance control device 5. Next, when the train is to depart, when the station control computer 9 determines that the departure time indicated by the timetable data has arrived,
The control data of the point 7 and the green signal request data to the traffic light 8 are transmitted to the relay interlocking device 3.

In this way, this system sequentially manages train operations for each station S or station group (divided service route) based on decentralized timetable data.

According to the above embodiment, decentralized timetable data is constructed in the station control computer installed for each station or station group based on the timetable data in the central management computer, and according to this decentralized timetable data, the station or station group Since the trains within the train are operated under control, there is no need to improve reliability by duplicating or triplicating the central control computer as in the past, and partial train operation changes can be easily made. Even if a failure occurs in a part of a transmission line or a failure in a device, only the relevant control range is affected, and manual control is limited to that range, making it easy to secure personnel.

In addition, in the above embodiment, the case of the train operation management method for managing the operation of trains was explained, but the operation management method of the present invention can also be applied to the operation management of transportation means such as buses, ships, airplanes, etc., and the same applies in this case. You can get a great effect.

〔Effect of the invention〕
