Abstract
The application provides a train tracking method, device and electronic equipment, and belongs to the technical field of rail transit control. The train tracking method comprises the following steps: in response to a train tracking instruction, acquiring line data determined based on block section information of each block section and switch information of each switch; determining a block section where a train currently locates, and receiving a current switch opening direction value sent by a computer interlocking subsystem; taking the block section where the train currently locates as a starting point, performing path search in the line data based on the current switch opening direction value, and obtaining a train tracking result. Through data structure and algorithm at the software level, the current state of the multi-opening-direction switch can be accurately analyzed and a unique travel path can be determined. The adaptation difficulty of the software system to the multi-opening-direction switch is fundamentally solved, so that the reliable operation of the CBTC system under complex station conditions is ensured without increasing the hardware cost and operation and maintenance complexity.
