Data processing system and method for track flaw detection

Abstract

The invention discloses a data processing system and method for track flaw detection, and the system comprises: a data collection unit which is used for collecting ultrasonic flaw detection data; a data processing unit which is used for receiving the ultrasonic flaw detection data and generating flaw characteristic data; and a communication unit which is used for transmitting the defect characteristic data to an upper computer unit. The programmable data processing unit is arranged at the front end, ultrasonic flaw detection data collection, filtering and flaw judgment are carried out in a hardware circuit mode, the hardware circuit can be triggered based on the same clock signal, it is guaranteed that multiple kinds of collected data are synchronous at each moment, processing and compression of a large amount of data are completed at the front end, the real-time performance and accuracy of the data processing system are effectively improved, meanwhile, the computing force load of a rear-end upper computer is reduced, and the problems that a traditional track flaw detection data processing system is high in rear-end computing force load and poor in real-time performance are solved.

Description

Technical field [0001] The present invention relates to a rail vehicle detection technologies, and particularly relates to a data processing system and method for flaw detection track. Background technique [0002] Train tracks is an important element for guiding traveling of the train. In exercising the train, the track will cause friction with the wheel train, and the vibration causes the track, the track and track bed gravel collision. Therefore, after the train tracks for a long time put into use, the track will produce fatigue damage or wear damage, the track will be damaged to varying degrees, problems such as damaged wear, dents, cracks, holes and loose corrugation defects. [0003] Currently, conventional testing methods for the use of large train track rail testing car. In the process of testing a high-speed, large-scale rail flaw detection car with its speed, strong adaptability lines, and high degree of automation equipment, has become the main means of detection field...
