Problems solved by technology

[0002] In the traditional train service control system, there is a situation that when the preceding train scheduled to transfer to the next station is delayed, the following train that will pass the next station will catch up with the preceding train, and because the preceding train is not in the If the station stops and slows down, the subsequent trains must also slow down, and the delay of the train will increase further

Embodiment 1

[0013] FIG. 1 is a configuration diagram showing a train service control system according to Embodiment 1 of the present invention.

[0014] In Fig. 1, in a service management system 1 (ground equipment), according to the information obtained from the CTC information acquisition device 11, the train position and speed state of the train in motion are estimated by the train state estimation device 12, and at the same time, the train travel prediction The device 13 predicts the train travel curve and the opening time of the track opening to the passing side within a certain period of time (usually tens of minutes).

[0015] In the service control support ground equipment 2 (ground equipment), the taxiing information selection means 23 searches the taxiing pattern database predetermined by the taxiing pattern generating means 21, while using the calculated current position and speed of the train and the information obtained by the train travel predicting means 13. Tracks turn on ...

Embodiment 2

[0048] In embodiment 1, although the grade is directly controlled and adjusted according to the sliding information, in embodiment 2, a sliding information display is provided on the train to indicate the sliding information to the driver, and the driver can control the train according to the sliding information speed.

[0049] Since the coasting control according to this system is simple, it is also sufficient in this way. For example, the driver compares the received taxiing information with the current position and speed, and when entering a section where taxiing should be performed, taxiing starts. Also, when the speed has reached the coasting target speed, the coasting target speed is maintained and travel is continued.

Embodiment 3

[0051] In this description, although the positions and velocities of the preceding train and the following trains are obtained from track line change information on the ground equipment side, the position and velocity information can be obtained directly from the preceding train through a communication device such as a train radio. The train gets.

[0052] That is to say, the service control support vehicle-mounted equipment 3 includes train information sending means for sending train position and speed information from the train, and the service control support ground equipment 2 includes train information receiving means for receiving train information on the ground, the train position and speed information. The speed information is obtained from the train instead of the train state derivation device 12 . In such a case, the prediction accuracy of the train travel is improved compared to the estimation from the track line change information in the embodiment.

Abstract

Problem: To obtain a train service control system in which inexpensive on-board equipment installed on existing systems and transmissions can be used, and when the train schedule is disrupted and the preceding train is diverted into the station, it is possible to Avoid substantial deceleration of subsequent trains and increased delays. Solution: Predict the train position and speed of the preceding train from the descending and lifting information of a track line by the train state estimation device 12; predict the preceding train from the state of the predicted preceding train by the train operation predicting device 13 The opening time of the track at the dispatching station; the sliding information of the subsequent train is selected from the predetermined sliding mode database 22 according to the opening time of the track predicted by the sliding information selection device 23, so that the following train passes through the track at maximum speed; the selected The sliding information of the following train is sent to the following train, and the following train is controlled to slide by the automatic train control device 32 according to the sliding information received by the information receiving device 31 of the following train.

Description

technical field [0001] The present invention relates to a train service control system in which, when a train schedule is disrupted and a preceding train is diverted into a station, subsequent trains can be prevented from greatly decelerating and an increase in delays can be avoided. Background technique [0002] In the traditional train service control system, there is a situation that when the preceding train scheduled to transfer to the next station is delayed, the following train that will pass the next station will catch up with the preceding train, and because the preceding train is not in the If the station stops and slows down, the following trains must also slow down, and the delay of the train will increase further. [0003] In Patent Document 1, in order to solve the above problems, a method is provided, in which an on-board device predicts and calculates the lane change of the passing track (track) that occurs after the preceding train enters the next station as ...
