Abstract
The present invention relates to a method and system for automatically identifying various information of a train. The method comprises using sensors to collect wheelbase information, processing the information by signal data processing devices, thereby providing information of a train, namely: arranging a plurality of sensors along the rail in the incoming direction of the train, dividing the sensors into at least three groups, each group comprising at least two sensors; analyzing and processing the signal data stream obtained from the sensors and collected when a train vehicle passes by, thereby acquiring the speed and wheelbase of the train, and further acquiring the train segmentation information; determining the vehicle type; acquiring hook locating information; determining the train arrival; determining the train departure; acquiring vehicle number. The present invention further comprises a system for carrying out the information method for automatically identifying information of a train. The present invention can provide a plurality of types of train information with high accuracy, and is easy to be carried out.
