Turnout control method and device

Abstract

The invention provides a turnout control method and device. The method comprises the steps of determining a first logic section where a turnout is located and an overrun area; based on the first logic section and the overrun area, respectively calculating a boundary for triggering a turnout expropriation request and a boundary for triggering an overrun area expropriation request, and sending a corresponding expropriation request to an LCS when a condition for sending the turnout expropriation request and / or the overrun area request is met; and according to the feedback information of the LCS, determining the type of expropriation of the turnout and the overrun area. Lock mechanisms are applied to track sections, turnouts, overrun and the like respectively. When the train leaves the turnout movable area, the current train can release the expropriation of the turnout, and the rear train can add a lock for the turnout and expropriate the turnout. According to the train control system based on train-train communication, by means of the mechanism, the time for pulling the turnout is advanced, the operation interval between trains is shortened, the operation efficiency of the trains is improved, and the operation pressure is reduced.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a switch control method and device. Background technique [0002] At present, the mainstream signaling system in the market is the CBTC (Communication Based Train Control System, Communication Based Train Automatic Control System) system based on train-ground communication. In the traditional CBTC system, the interlocking subsystem is responsible for the control of trackside equipment (such as switches, etc.). The interlocking subsystem regards the front of the turnout, the straight direction behind the turnout, and the lateral direction behind the turnout as a logical section. Only when the train completely clears the logical section where the switch is located, the interlock will unlock the switch and the approach, and the rear car can enter the turnout according to the newly processed approach. When the front vehicle and the rear vehicle pass through the straigh...

AI Technical Summary

Problems solved by technology

When the front vehicle and the rear vehicle pass through the straight or sideways of the turnout respectively, this processing method makes the timing of moving the switch lag behind, and consumes more time for handling the approach, and the timing of the rear vehicle passing the turnout is limited

Both the front vehicle and the rear vehicle travel sideways or straight to the turnout. In the CBTC system, the rear vehicle can only enter the switch area after the front vehicle has completely cleared the logical section, restricting the operation of the rear vehicle.
