Example Embodiment

[0015] Blockchain technology uses a network consensus mechanism and an asymmetric encryption algorithm to realize trusted direct transactions between two strangers without a third-party guarantee. All nodes in the network are interconnected in pairs. When a transaction occurs, all nodes in the network will record transaction process information at the same time. When a certain node is abnormal, other nodes in the network will use the recorded information to restore the abnormality node. For the defects of the vehicle-to-vehicle communication train control system in the prior art, the blockchain concept can be used to solve the problem.

[0016] The train-vehicle communication train control system based on the blockchain technology of the present invention includes a train monitoring system, an object controller, a data communication system and an on-board controller VOBC arranged on the train. The CBTC system for vehicle-to-vehicle communication in the prior art is still retaine...

Abstract

The invention discloses a block chain technology-based train-train communication train control system. The system comprises object controllers and a train-mounted controller arranged on a train, wherein a route is divided into a plurality of object controller dominated areas, which are controlled by different object controllers; after a train accesses an area and successfully registers, the respective object controller is used for transmitting a maintaining communication train list ID to the new accessing train, direct communication is established between the train and other trains in the areaof the object controller according to the list ID, and the object controller and the train-mounted controllers are interconnected and communicated in the object controller dominated area, full-routeequipment status information can be recorded and updated in real time, and train control can be realized at the train end by the train-mounted controller based on other train location information recorded by the train-mounted controller, the location information of the train-mounted controller and the route equipment status information. The system can completely get rid of dependence of train related train control functions on OC, so that the system complexity can be reduced, and the control flexibility can be improved.

Description

technical field [0001] The invention relates to rail transit technology, in particular to a train control system. Background technique [0002] The traditional CBTC system is mainly based on ground control, and there are problems such as a large number of equipment, complex control, high maintenance costs, and it is not conducive to line upgrading and interconnection. At present, the CBTC system based on vehicle-to-vehicle communication that is being explored in the industry can greatly optimize the traditional CBTC system. From the system architecture level, the vehicle-to-vehicle communication train control system cancels the traditional ZC (Zone Controller, realizes centralized train interval control), CI (computer interlocking, realizes trackside signal equipment control) and other equipment, and uses the enhanced on-board control The system, through the direct communication between vehicles, realizes adjacent train identification, movement authorization calculation, dr...
