Problems solved by technology

[0003] However, this driving control method relies too much on the communication status between the train and the OCC and the judgment of the OCC. Once there is a communication failure between the train and the OCC, the train data cannot be fed back in time, and the control data issued by the OCC cannot be received by the train in time. OCC issues wrong control commands due to misjudgment, etc., and the train cannot intelligently adjust the driving status autonomously, which may lead to serious traffic accidents

Abstract

The invention provides a train anti-collision early warning method and device, and applied to control equipment arranged on a train. The method comprises the following steps that a radio-frequency signal reading unit is used for reading information in radio-frequency signal tags arranged at intervals along a rail in a driving process, and the current position of the train is determined according to the currently read information in the radio-frequency signal tags; the current running data of the train are obtained, and the current running data comprise the current driving speed and the drivingdirection of the train; and a driving notification message of the train is generated according to the current position and the current running data, the driving notification message of the train is broadcast through a wireless communication unit, so that mobile terminals of other trains or near-rail workers receiving the driving notification message of the train are enabled to adjust the drivingstate or send an alarm notice according to the driving notification message of the train. In this way, the risk of collision with the other trains or the near-rail workers can be reduced through autonomous action of the train without depending on OCC control.

Description

technical field [0001] The present application relates to the technical field of rail transit, and in particular, to a train anti-collision method and device. Background technique [0002] Please refer to figure 1 , in rail transportation, trains usually need to communicate with the station’s Operating Control Center (OCC). OCC makes judgments based on the current position and speed of each train to control the operation of each train and prevent traffic accidents. [0003] However, this driving control method relies too much on the communication status between the train and the OCC and the judgment of the OCC. Once there is a communication failure between the train and the OCC, the train data cannot be fed back in time, and the control data issued by the OCC cannot be received by the train in time. OCC issues wrong control commands due to misjudgment, etc., and the train cannot intelligently adjust the driving status autonomously, which may lead to serious traffic accident...
