Train speed monitoring system and method of point type train control system

Abstract

The invention discloses a train speed monitoring system and method of a point type train control system. The method comprises the following steps that S1, an interlocking system determines occupationor clearing of track sections according to detection information of vehicle occupation detection equipment, and train positioning is achieved; S2, an automatic train monitoring system identifies a train through a train group number and obtains the length of the train; S3, the automatic train monitoring system periodically receives the occupation clearing state of each track section of a line fromthe interlocking system; S4, the automatic train monitoring system obtains the length of each track section from line configuration data; and S5, the average running speed of the train in the sectionis obtained by dividing the train displacement by the track section occupation time. According to the train speed monitoring system and method, under the condition of train-free continuous two-way communication, monitoring of a dispatching center on the train speed is achieved, and train overspeed / low-speed early warning of the point type train control system is achieved.

Description

technical field [0001] The invention relates to a rail traffic signal system, in particular to a speed calculation and monitoring method for a point-level train automatic monitoring system (ATS, Automatic Train Supervision). Background technique [0002] The point-type train control system has the advantages of less investment and lower maintenance costs, and is especially suitable for lines with low passenger flow and low requirements for driving efficiency, or as a communication-based automatic train control system (CBTC, CommunicationBased Train Control System) The backup degraded mode of the CBTC system will continue the normal operation of the system when the vehicle-ground communication is interrupted or the trackside controller fails, and the continuous two-way communication between the vehicle and the trackside cannot be guaranteed. [0003] The traditional point mode controls train operation in a fixed block mode. When the train passes the pre-set signal point on t...

Problems solved by technology

[0004] Since train-to-ground communication can only be carried out at a specific location, continuous communication with the train cannot be carried out. During the operation of the train, the dispatcher cannot obtain real-time operating information such as the precise position of the train and the speed of the train, and cannot intervene at any time. In addition, the train passes through a The signal point, before reaching the next signal point, can only operate according to the mobile authorization information given by the previous signal point. If the state of the trackside equipment changes during the process, such as the train has read the information protected by the signal machine. The screen door where the platform is located is accidentally opened, or someone presses the emergency closing button of the platform, etc., and the train continues to move because it cannot obtain information. At this time, the train driver must always pay attention to the status changes of the trackside equipment. The safe operation of the train is completely guaranteed by the driver.
