Dynamic detection system under high-speed running state of train and equipment thereof

Abstract

The invention relates to the technical field of dynamic detection of trains, and discloses a dynamic detection system under a high-speed running state of a train. The dynamic detection system under the high-speed running state of the train comprises rails, sleepers, a vehicle-mounted receiver, a ground control room, a wireless transmission device, a transverse displacement sensor, a vertical displacement sensor, a vehicle speed sensor, a ground control box, a signal amplifier, an information processor, an A / D converter, a central processing unit and a vehicle information storage device; the signal amplifier, the information processor, the A / D converter, the central processing unit and the vehicle information storage device are arranged in the ground control box; the vehicle-mounted receiver is installed in a vehicle driving room through a bolt; and the transmitting end of the wireless transmission device is connected with a control machine in the ground control room through a signal terminal connecting wire. According to the dynamic detection system under the high-speed running state of the train and the equipment thereof, the abrasion degree of wheel treads and the defect damage degree of the wheel treads can be detected during driving, the abrasion degree or the damage degree of bearings at the joints of wheels and axles can be detected during driving, and the driving safetyof the train is improved.

Description

technical field [0001] The invention relates to the technical field of train dynamic detection, in particular to a dynamic detection system and equipment thereof under a high-speed train running state. Background technique [0002] The EMU dynamic fault detection system can detect faults in the operation of the EMU, which is conducive to improving the safety factor of the EMU operation. It can automatically detect the parts of the EMU and improve the work efficiency of the maintenance station, especially when the train is running at high speed. The tread wear of the wheels and the wear of the wheel bearings will cause traffic safety hazards. Although the vehicle body is now equipped with a dynamic image detection system for operating faults, it is used to monitor whether the parts on the chassis of the body are indeed falling. When the vehicle body vibrates, it will bear a large force, but it is impossible to detect the degree of wear of the wheel tread and the degree of dam...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a dynamic detection system and its equipment under the high-speed running state of the train, which can detect the wear degree of the wheel tread and the damage degree of the wheel tread during driving, and can also detect the degree of damage of the wheel tread. The wear or damage degree of the bearing at the connection with the axle solves the problem that it is impossible to detect the wear and tear of the wheel tread and the damage of the wheel tread during driving, and it is also impossible to detect the wear or damage of the bearing at the connection between the wheel and the axle. The question of damage
