Problems solved by technology

[0014] At present, the rail transit CBTC overspeed protection system has a regional controller on the ground. After the regional controller calculates the movement authorization of the train, it sends it to the on-board controller on the train. The on-board controller calculates the maximum safe running speed of the train. Now The following problems exist in the e

Abstract

The invention relates to a train overspeed protection method and a train. The method comprises the following steps: a train is used for broadcasting the location information of the train to other trains and receiving location information broadcast by other trains; the train is used for acquiring speed-limiting state information of the route, including the occupation state information of the train in each physical section of the route; and the train is used for calculating the movement authority of the train at current time according to the location information broadcast by other trains and the speed-limiting state information. Compared with the prior art that information is needed to be transmitted to the train after a region controller forwards the location information and calculates the movement authority, the technical scheme of the method has the advantages that the process of transmitting the movement authority and location information to the train by the region controller can be reduced, so that data waiting delay can be reduced, and overspeed control can be realized in time.

Description

technical field [0001] The invention relates to the field of rail traffic control, in particular to a train overspeed protection method and a train. Background technique [0002] The rail transit overspeed protection function is to calculate the train speed protection curve according to the position of the train ahead, the state of the trackside equipment and the speed limit, and perform overspeed protection on the train according to the speed protection curve. [0003] In the existing CBTC (Communication Based Train Control System, automatic train control system based on wireless communication), the equipment related to the overspeed protection system includes on-board controller equipment, area controller equipment, interlocking equipment, trackside equipment and communication equipment, wherein the trackside equipment It mainly includes signal machine, axle counting, turnout and other equipment. [0004] In existing CBTC systems, trains regularly send their location info...
