Vehicle-mounted synchronous communication and detection integrated system and method for high-speed maglev train

Abstract

The invention discloses a vehicle-mounted synchronous communication and detection integrated system and method for a high-speed maglev train. The system comprises the maglev train, a signal processing module, a vehicle-mounted base station, a ground base station and a ground partition control unit, wherein the signal processing module and the vehicle-mounted base station are arranged on the maglev train; a standard time slot of a train is divided into 16 sub time slots, and the first time slot is set as a train-ground communication time slot and is used for performing synchronous communication with a ground base station; the other time slots are respectively set as a detection time slot and a signal processing time slot, in the detection time slot, a train obtains position information, and meanwhile, a vehicle-mounted base station transmits linear frequency modulation continuous wave signals with different frequency modulation slopes and periods forwards, receives echo signals and transmits the echo signals to a signal processing module; and in the signal processing time slot, the signal processing module processes the received echo signal. The free time slot of non-local-train communication in maglev train communication is used for detecting the front rail, the safety and reliability of the maglev train during operation are improved, the cost is low, implementation is easy, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a vehicle-mounted synchronous communication detection integration system and method of a high-speed maglev train. Background technique [0002] Since the maglev train adopts unmanned driving technology, in order to ensure the safety of the maglev train during normal operation and prevent road blockage caused by sudden accidents, it is necessary to detect the front track when the maglev train is running, so that the train can detect and respond to emergencies in time. situation. [0003] At present, the railway system is very deficient in early warning of sudden accidents. In the high-speed railway, before the official start every day, the safety of the line will be confirmed by two-way split empty trains. However, this method cannot better guarantee the safety of empty trains, and cannot respond to unexpected situations during the operation of manned trains, wh...
