Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] The basic principle of the present invention to achieve the purpose of the invention: Establish the mathematical model of the turnout based on the line information related to rail transit, and use the interlocked track circuit occupancy / clearance information to perform logical occupancy and logical exit according to the type of train and the locking state of the turnout Qing's three-point inspection, supplemented by train position report when there is a train position report, comprehensively uses the state machine expert system to realize adaptive train tracking in complex turnout states.

[0036] like figure 1 As shown, the adaptive train tracking method in this complex turnout state includes the following steps:

[0037] Step 1: track line data initialization, load data configuration information such as straight track track segment (Segment) / track idle dete...

Abstract

The invention discloses a tracking method of self-adaptive trains in a complicated turnout state. The method includes step one, initializing track line data and loading transient voltage suppressor (TVS) data configuration information in a straight track zone Segment/ track free detection zone; step two, initializing train data; step three, starting a main circulation body: reading in turnout states and TVS state messages coming from an interlock and reading in position report messages coming from a vehicle-mounted controller; step four, judging whether interlock faults exist; step five, judging whether trains are on line from a vehicle segment; step six, going through all trains in a system; step seven, judging conditions of a position report, inquiring a TVS corresponding to a train envelope in messages coming from the interlock and judging whether the TVS has endpoint logic voidance or not; step eight, inquiring the TVS corresponding to the train envelope in messages coming from the interlock and inquiring the position report of the train in messages coming from the vehicle-mounted controller if the position report exists; and step nine, finishing the main circulation body and skipping to step three.

Description

technical field [0001] The invention relates to a method for realizing train tracking, in particular to an adaptive train tracking method compatible with various turnout states in an urban rail transit control system. Background technique [0002] Urban rail transit trains have high running density, short distance between stations, and high safety requirements. The automatic train control system (ATC) and the train itself need to know the precise position of the train on the line in real time. The automatic train control system distributed on the trackside and on the train According to the relative position of the trains on the line, each train is monitored, controlled, dispatched and safety protected in real time and dynamically. On the premise of ensuring the safety of train operation, the efficiency of the system is maximized to provide passengers with the best service. [0003] Train location information plays an important role in automatic train control technology. The ...
