Train control system and train control method

Abstract

A train control method which utilizes a ground radio communication unit, which communicates with an onboard communication unit installed on a train, and a balise, which is installed at a predetermined stop position where the train stops and capable of communicating with the train, and is used to calculate a stop limit position to be given to the train on the basis of information obtained via the ground radio communication unit in order to control the operation of the train in a predetermined section. When the radio communication between the onboard communication unit and the ground radio communication unit is disrupted, a radio communication disruption setting section is set with the inclusion of the section where the radio communication is disrupted; the on-track state of a train which is traveling inside the radio communication disruption setting section is estimated on the basis of a first stop limit position which causes the train to travel to the position of the balise, or a second stop limit position which is set ahead of the communication disruption setting section, and the last received position of the train; and the operation of the train is controlled on the basis of the estimated on-track state of the train.

Description

[0001] Related Applications Cited [0002] This application is based on the prior Japanese Patent Application No. 2012-268515 filed on December 28, 2012, and enjoys the priority of this application. This application uses this application as a reference and includes the entire content of this application. technical field [0003] This embodiment relates to a train control system and a train control method. Background technique [0004] In recent years, a train control system has been developed that wirelessly notifies a ground-side control device of a train position detected by the train itself. This system can set the train stop limit position with a higher resolution than the safety function of the existing track line, so that the train operation interval caused by the moving block can be shortened. Moreover, compared with the large amount of complicated wiring required for track lines, there is less ground equipment, which is expected to reduce equipment costs. [0005] ...

Problems solved by technology

[0005] However, if the wireless base station on the ground side fails and a section where wireless communication cannot be performed occurs, the position of the vehicle in the section cannot be grasped on the ground side, and the stop limit position cannot be notified to the train, so the train runs on both sides of the section interrupted
