Train communication management method of TACS system

Abstract

The invention discloses a train communication management method of a TACS system. The method comprises the steps that a train establishes communication with an ATS and an RMC in a communication area; the RMC registers and tracks a communication train in a communication area of the RMC; the RMC plans reserved path resources according to the route requests and path planning of the multiple trains; the RMC tracks the position of each train in the communication area in real time, searches forward from the position of the head of the current train in the route running direction based on a planned path, searches an adjacent front train, informs the front train information in combination with an adjacent area, judges the front train needing to establish communication with the current train for the current train, and informs the VOBC of the current train of the ID of the front train; and when the train VOBC receives the front train which is identified by the RMC in an auxiliary manner and needs to establish communication, the train VOBC determines the situation and establishes communication with the unique front train. According to the invention, direct communication between vehicles and real-time interaction of main operation information are realized.

Description

technical field [0001] The invention relates to a train communication management method of a TACS (train autonomous operation system based on train-to-vehicle communication) system. Background technique [0002] In principle, the vehicle-to-vehicle communication system increases the wireless communication capability between the vehicle-mounted systems to the CBTC system based on vehicle-to-ground communication. Based on the wireless communication between the front and rear vehicles, the real-time operation safety information of the train is communicated. Since the operation of the train is affected by the allocation of traffic resources, On the same resource planning route, there is a competition relationship between the front and rear trains for running resources, so there will be mutual influence in operation. The existing communication management has the following patented technologies: [0003] The existing invention patent with the publication number CN109677461A divid...

Problems solved by technology

Disadvantages: There is a boundary in the jurisdiction of the object controller. According to the solution in this technical document, after the train enters the corresponding jurisdiction, it needs to establish communication with all communication trains in the jurisdiction. Due to the boundary of the jurisdiction, when the train crosses the jurisdiction boundary In the process, in the switching process of establishing communication with different object controllers, there must be discontinuity in train communication, and communication with some trains is suddenly established, and communication with other trains is disconnected

There are shortcomings and deficiencies: the train management unit under this technical document needs to combine the information of the route ahead and the information of the train operation diagram, and the sequence of the planned operation diagram may be inconsistent with the actual sequence of the train line, so the sequence of the planned operation diagram It is judged that the train sequence connection relationship established may not be the actual operation sequence, and the train communication sequence of the sequence link caused by the deviation between plan and actual operation is not accurate enough

There are shortcomings and deficiencies: pay attention to the locked position information of the switch position as the basis for identifying the vehicle in front. If the position of the switch is not locked, it is considered that the approach does not have connectivity, and the vehicle in front under the corresponding path cannot be identified until the position of the switch is turned in place. Recognize and establish communication with the preceding vehicle on the connected path, lack of predictability

The relative distance comparison method needs to calculate the relative distance of all trains within the range of the approach, and the comparison method lacks continuity
