Train positioning and degradation resource management system and method based on near field communication

Abstract

The invention provides a train positioning and degradation resource management system based on near field communication. The train positioning and degradation resource management system comprises a vehicle-mounted communication module, a trackside passive communication module and a trackside active communication module, the vehicle-mounted communication module is arranged on a train and is in two-way communication connection with a vehicle-mounted controller; the trackside passive communication module and the trackside active communication module are both arranged beside the trackside, the trackside passive communication module and the trackside active communication module are both in two-way near field communication connection with the vehicle-mounted communication module, and the trackside active communication module is in two-way communication connection with a target controller. Operation control of the train in the normal mode and the degradation mode is processed by the vehicle-mounted controller, an axle counter and a transponder are replaced, the engineering construction cost is saved, the types of ground equipment are reduced, the complexity is reduced, and the functions of the ground equipment are simplified.

Description

technical field [0001] The invention relates to the technical field of rail transit signals, in particular to a short-distance communication-based train positioning and degraded resource management system and method. Background technique [0002] Currently, urban rail transit generally adopts vehicle-to-ground communication-based train control (CBTC) system, and is developing a next-generation signaling system based on vehicle-to-ground communication. [0003] For the CBTC system, when the wireless communication between the vehicle and the ground fails, it needs to be downgraded to interlock or (point ATP / ATO) mode operation. At this time, the system relies on the ground interlocking system to complete the interlocking logic operation and the forward movement authorization calculation required by the point-type ATP by collecting information such as section occupancy and clearance output by the axle counting equipment, and the active transponder will point-type ATP Mobile au...

Problems solved by technology

[0006] In order to solve the technical problem of complex ground equipment of the train control system in the existing degraded mode, the present invention provides a train positioning and degraded resource management system based on short-distance communication, which is completed by the on-board controller in both the normal mode and the degraded mode. In degraded mode, there is no need for axle counter and transponder equipment, which saves the cost of engineering construction, reduces the types of ground equipment, reduces the complexity, and simplifies the functions of ground equipment
