Distributed type station train number tracing logical method

Abstract

The invention discloses a distributed type station train number tracing logical method. By means of the method, the functions such as train number creation, tracing, deletion and recovery of a CTC / TDCS can be effectively achieved. In the field use process, a tracing system is released downwards to stations in a distributed manner, and the influence scope generated when the stations are upgraded and reconstructed is small; single-station tracing data are configured concisely, arithmetic logic is clear, and fault tolerance can be achieved well and a train can be resumed when an abnormal station yard is shown; train number tracing among the multiple stations can be continued automatically and seamlessly, artificial data configuration is not needed, and the method can also be adapted to special station yard connection; and the train is traced in the interstation operation direction among the stations, and abnormal conditions such as train number backspacing and train number reverse tracing cannot occur.

Description

technical field [0001] The present invention relates to the field of railway signaling systems, in particular to a logic method for tracking train numbers at distributed stations Background technique [0002] CTC / TDCS system (decentralized autonomous dispatching centralized system / railway dispatching command system) is currently widely used in the field of railway rail transit. The CTC / TDCS system can supervise and control the operation of trains and help traffic dispatching commanders manage the entire train. It plays an extremely important role in improving the efficiency of rail transportation and ensuring the safety of operation. Among them, the management of the train number is an important foundation of the entire CTC / TDCS system. Only when the tracking of the train number is completed, can the follow-up other cores such as automatic train point reporting, occupancy loss, close tracking alarm, and automatic routing of routes be realized. Function. [0003] Currently,...

AI Technical Summary

Problems solved by technology

The disadvantage is that when the basic data of a station is modified due to construction and renovation, the entire tracking system of the center needs to be updated and restarted, which will affect the information output of other stations and is not conducive to dispatching and commanding

The disadvantages are: a. In general medium and large stations, the link relationship of station objects is extremely complicated, especially for stations with a large number of switches, the system needs to maintain a huge search tree structure

b. It is very difficult to track the recovery of trains in scenarios such as light train jumping or poor shunting "undefeated" in single-car trains

c. Under abnormal scenarios such as flickering, lagging or wrong station display, it will lead to logical tracking errors of train numbers

For example, when a train runs from Section 1 to Section 2, and Section 1 is cleared and occupied by a fault again, it may cause the train number to be tracked back, which is not in line with the actual situation.

d. Trains are transferred between stations through preset methods. Once the preset is lost or lagged behind, it will lead to the inability to connect between stations

The inter-station block mode and the inter-station connection mode are different from station to station (some stations do not have intervals), which will also cause the preset function to fail
