Description

Backup operation method and device of train, electronic equipment and storage medium Technical Field The present invention relates to the field of rail transit technologies, and in particular, to a method and apparatus for running a train in reserve, an electronic device, and a storage medium. Background In a communication-based train automatic control (Communication Based Train Control, CBTC) system, accurate positioning of trains and continuous acquisition of movement authority (Movement Authority, MA) is highly dependent on stable, real-time train-ground communication. Existing CBTC systems typically take a conservative downgrade operating strategy once the primary and backup communication channels fail, or the train receives an emergency downgrade command from the ground control center. These strategies typically include manual driving strategies where the driver controls the train to creep at very low speeds via visual or ground signals, and full stopping strategies where the train is stopped in place waiting for communication to resume. However, when the above strategy is executed, the train runs or stops at an extremely low speed, which seriously affects the passing ability of the line, resulting in a large area of late time of the train, and reducing the operation efficiency.
