Description

  The present invention relates to a train operation management device using a train arrival time prediction process and a train arrival time notification method.

  The main function of an automatic route control device (PRC: Programmed Route Control), which is the core of the train operation management device, is to obtain a train operation schedule and track the train position to track the train. Provides various types of passenger guidance information, such as train type, destination, arrival / departure number, and departure time, to the automatic broadcasting system for passenger information installed at each station, departure indicators for station platforms, and destination indicators. It also has functions. This passenger guidance function is naturally an essential function in providing passenger services.

  Guidance information is not useful once the schedule is disrupted due to an accident, etc. In this case, the dispatcher or station staff confirms the train operation status by telephone or radio to the station. The train arrival time is judged and the information is broadcast to the passengers manually.

  However, since the commander and station staff need to carry out the operation and arrangement work for recovery of the delay of the train and also the work of the guidance broadcasting, at the station where the manpower is not enough, or at the station where the train operation density is high, the train There was a problem that the passenger information service at the time of delay was not enough.

  In order to solve this problem, Patent Document 1 discloses a technique for detecting a delay time for an operation schedule by tracking a train position and outputting the detected time to a guidance display device at a station. However, this technology has low utility because information that is highly useful for passengers waiting for the arrival of the train is not the delay time but the arrival time at the station. Actually, there are some current departure signs that display the delay time of the train, such as “15 minutes delay”, but passengers cannot accurately predict the arrival time at the station with this information as a target. It was difficult and could not necessarily meet the needs of passengers.

  On the other hand, Patent Document 2 discloses a technique for outputting a predicted arrival time at a station to a display. According to this technique, the central supervisory control device first obtains the train passage time from the station control device of each station, and calculates the error from the scheduled time of the train schedule and the train speed. Then, the station control device at each station receives error information including the error and the train speed from the central monitoring control device via the LAN, and calculates the estimated arrival time based on the error information.

  In this technology, not only is it necessary to increase the functionality of the station control device installed at each station, but also a high transmission capacity for transmitting information from a plurality of station control devices to the central monitoring control device via the LAN. Since it is necessary to provide communication facilities, it is disadvantageous in terms of facility costs. In addition, since the plurality of station control devices individually calculate the estimated arrival time, there is a problem that the accuracy of the estimated arrival time may be low due to a shift in the transmission / reception timing of information for each device.

  Moreover, although patent document 3 is disclosing the technique which notifies delay information based on the arrival time of the station immediately before acquired from the performance diagram in order to eliminate such a problem of equipment cost, patent document 1 and Similarly, the train delay time was reported to passengers.

Further, the automatic route control device 1, the PRC console 20, the diamond correction device 23, the diamond creation device 3, and the guidance central device 4 are connected to the diamond line L3. The first and second control lines L1 and L2 have a redundant configuration in which the same data always flows, and even if one of them fails, communication can be continued by the other.

  On the other hand, the guidance line L4 multi-connects the guidance central device 4 and the guidance device 60 of each station 6, and the control line L5 multi-connects the CTC central device 5 and the CTC device 61 of each station 6. However, these communication lines are not limited to LANs using metal lines (metal cable lines), but may be wireless communication lines or optical lines, and more specifically ATM (Asyncronous Transfer Mode). It is also possible to adopt a dedicated line other than the LAN such as a line or a frame relay line.

  In this way, the devices and the like constituting the train operation management device construct a communication network and execute the train operation management in cooperation with each other through inter-device communication. The effects of each device will be described below.

  The diagram creation device 3 is a so-called EDP device (EDP: Electric Data Processor), creates a schedule for each day according to a train schedule, and uses the schedule control information 1 and the guidance central control device as the schedule diagram information D. 4 to send.

  The automatic route control device 1 is a so-called PRC device that tracks a train position in accordance with a train detection signal input from each track circuit, and based on the tracking information and the operation diagram information D received from the diagram creation device 3. Then, a route control signal R for appropriately controlling the route of the train is transmitted to the CTC central device 5.

  The CTC central device 5 transmits a control signal C such as a traffic light or a switch to the CTC device 61 of each station 6 according to the route control signal R. Based on the control signal C, the CTC device 61 controls a traffic light, a switch, etc. via an interlocking device.

  On the other hand, the guidance central device 4 is a so-called TID central device (TID: Traffic Information Display) and is based on the train type, destination, arrival / departure number, departure time, etc. received from the automatic route control device 1. Information G is generated and transmitted to the guidance device 60 at each station 6.

  The guidance device 60 is a passenger guidance device such as an automatic broadcasting device in a station yard or a departure sign, and guides the train operation status to the passenger based on the passenger guidance information G received from the guidance central device 4. For example, guidance is performed by voice in the case of an automatic broadcasting device, and is performed by character display in the case of a departure sign.

  The characteristic part of the present invention is the function of the train arrival time prediction unit 231 provided in the diamond correction device 23. When the travel schedule is corrected by the diamond correction device 23, the automatic route control device 1 first transmits the train position tracking information P to the diamond correction device 23. The train arrival time prediction unit 231 predicts the arrival time of the train for each station 6 based on the operation schedule and the tracking information P of the train position, and transmits this arrival time information T to the guidance central device 4. .
