Train running control system with vehicle on-board controller as core

Abstract

The invention discloses a train running control system with a vehicle on-board controller as a core. The train running control system comprises a intelligent vehicle on-board controller IVOC arrangedon each train, wherein the IVOC comprises a train-to-train communication device, an initiative identification device and a main control device. The train-to-train communication device is used for acquiring current running information of other trains; the initiative identification device is used for determining whether an obstacle exists in front of the running direction of the train, and if the obstacle exists, determining a distance between the obstacle and the train; the main control device is used for calculating first movement authority MA of the train according to the current running information of the train and the current running information of the adjacent front train equipped with the train-to-train communication device, determining the first MA as a final MA if no obstacle existsin front of the train, determining a second MA of the current train according to the distance if the obstacle exists, and determining a final MA according to the first MA and the second MA. By virtueof the control system provided by the invention, when the obstacle exists in front of the running direction of the train, the tail collision or more serious accidents of the train can be avoided. Onthe premise of ensuring the safety running of the train, the running efficiency of the train can also be increased.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a train operation control system with a vehicle-mounted controller as the core. Background technique [0002] The Communication Based Train Control (CBTC) system uses communication media to realize two-way communication between trains and ground equipment, and replaces track circuits as media to realize train operation control. [0003] The traditional CBTC system is mainly based on ground control. The train registers with the zone controller (ZC) on the ground, accepts the control of ZC, and actively reports the position to ZC. ZC calculates the movement authorization (Movement Authority) for the train within the jurisdiction area. , MA), through the continuous two-way wireless communication between the vehicle and the ground to realize the interaction of vehicle-ground information, and realize the tracking operation under the target-distance-based mobile block system.

Problems solved by technology

[0005] However, the CBTC system based on vehicle-to-vehicle communication relies on direct communication between trains. Once there is a train without communication equipment or communication equipment failure in front of the vehicle, the vehicle will not be able to know the operation of other vehicles ahead. The mobile authorization error caused by the vehicle, resulting in serious danger

In addition, if there is an obstacle in front of the train, such as an object entering by mistake, or other equipment suspended on the train track, or when trees or other obstacles appear on the track due to extreme weather, the existing vehicle-to-vehicle communication based The CBTC system also cannot realize the identification of obstacles, resulting in the failure of the train to stop in time, resulting in danger, which will cause harm to the train and even the passengers, and the consequences are very serious
