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.

Automatic identification method and system for train information

The present invention relates to a trailer system, and particularly to a self-driving trailer system for a radiation imaging inspection system and a method for inspecting a vehicle by radiation imaging of a vehicle through the trailer system. The self-driving trailer system comprises two trailers symmetrical in structure. Each of the trailers comprises a driving device, running wheels, a trailer body, a carrying device, a lift cylinder, a balance wheel, and two pairs of guide wheels. The driving device, the running wheels, and the balance wheel are coupled with the trailer body. The carrying device is coupled with the trailer body through the lift cylinder. A front carrying arm and a rear carrying arm can clamp front wheels of a vehicle under inspection, and move upwards and downwards by the lift cylinder. The trailer system according to the present invention is smooth and reliable in operation and simple in structure, and is applicable to different diameters of wheels of container lorries under inspection and is convenient in operation.

Trailer system and method for inspecting vehicle by radiation imaging of vehicle through trailer system

The present invention discloses an radiation imaging system, comprising: an accelerator for generating rays which penetrate through the objects to be inspected and an synchronous signal; a detector with a plurality of detecting modules, adapted for detecting rays; a signal processor for generating a selection signal according to the synchronous signal, so as to select a detecting module for detecting the rays; a data converter for converting the signal detected by said detecting module into digital data, and then buffering the digital data in said signal processor; and a communication controller connected to an image processor, adapted for transmitting the digital data buffered in said signal processor to said image processor. The system according to the present invention allows high-speed and stable data acquisition and data conversion and accurate and reliable data transmission, when the data amount is significant.
