Active identification system for hidden train exclusion and hidden train exclusion method

Abstract

The embodiment of the invention discloses an active recognition system used for hidden train elimination and a hidden train elimination method. The system comprises a communication subsystem, an active recognition subsystem and a master control subsystem. The communication subsystem is used for receiving first position information of the nearest adjacent train with a communication function; the active recognition subsystem is used for determining a second distance; and the master control subsystem is used for calculating a first distance according to second position information of a current train and the first position information and confirming that a hidden train is eliminated if it is judged that the difference between the first distance and the second distance is smaller than the length of the train. The first position information of the nearest adjacent train with the communication function is received through the communication subsystem, the active recognition subsystem recognizes the second distance, the master control subsystem obtains the second position information of the current train to judge and confirm that the hidden train is eliminated, hidden train elimination efficiency is improved, and safe and efficient operation of the train is further achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of rail transit, and in particular to an active identification system for removing hidden trains and a method for removing hidden trains. Background technique [0002] Based on the traditional CBTC mobile block train control system, wireless communication transmission means are used for two-way communication between the train and the ground, so that the train can obtain the distance from the train in front in time, and calculate the braking curve to improve the traffic capacity of the section. The system mainly includes: vehicle-mounted VOBC equipment, ground zone controller ZC subsystem, interlocking CI system, wireless transmission DCS system, central control ATS system, and transponder equipment for positioning and point backup, etc., such as figure 1 shown. [0003] The urban train control system based on vehicle-to-vehicle communication is an improvement and upgrade of the traditi...

Problems solved by technology

However, in the process of train tracking establishment, there is a lack of automatic exclusion of hidden trains on the line (communication failures, train positioning failures and other trains that cannot exchange information such as train positions with normal trains), so when there are hidden trains, it is often not normal automatic tracking
