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 sig

Embodiment 1

[0040] refer to Figure 1 to Figure 3 Shown, the train speed monitoring system of a kind of point-type train control system comprises: interlocking system, according to the detection information of vehicle occupancy detection equipment (such as axle counting system, utilize track sensor, counter record and compare to drive into and drive out of track The axis number of the section) to determine the occupation or clearance of the track section, realize the positioning of the train, and send the occupation or clearance status of the track section and the train position information to the automatic train monitoring system;

[0041] The automatic train monitoring system communicates directly with the interlocking system to obtain the track section occupancy or clearing status and train location information, and calculates the train passage according to the occupancy or clearing status of each track section, combined with the length of the train and the length of the track section ...

Embodiment 2

[0054] refer to figure 2 and image 3 Shown, the train speed monitoring method of a kind of point train control system, comprises the steps:

[0055] S1, the interlocking system determines the occupancy or clearing of the track section according to the detection information of the vehicle occupancy detection equipment, and realizes the positioning of the train;

[0056] S2, the automatic train monitoring system identifies the train through the train group number, and obtains the train length of each car according to the train formation information;

[0057] S3. The automatic train monitoring system periodically receives the clearing status of each track section of the line from the interlocking system, records the time when each track section changes from idle to occupied, and the time when the occupied train completely clears the track section, and calculates two or the difference as the time interval occupied by the orbit segment;

[0058] S4, the automatic train monitor...

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...
