Abstract

The invention discloses an automatic centering control system with a self-adaptive line adjustment function. The automatic centering control system comprises a steel a rail flaw detection car map management system, an automatic centering control system and a steel rail flaw detection car detection system. The steel rail flaw detection management map system comprises a ground map computer and a vehicle-mounted map computer. The steeel rail flaw detection car detection system forms a detection B-type graph to realize steel rail joint identification and synchronous positioning. The steel rail flaw detection vehicle map management system provides accurate relative positioning mileage coordinates. The automatic centering control system obtains an automatic centering pre-estimated given value for self-adaptive adjustment according to the centering control parameter sample. The technical problems that an existing automatic centering control system is lagged in control, manual adjustment and given intervention are needed in a small-curvature-radius line, and manual operation can only be relied on when heavy snow covers the line can be solved.

Description

technical field [0001] The invention relates to the technical field of railway engineering, in particular to an automatic centering control system for a rail flaw detection vehicle with adaptive adjustment of a line. Background technique [0002] Ultrasonic rail flaw detection is currently recognized worldwide as one of the most effective and important means to detect internal rail damage early, reduce the risk of rail breakage, and improve train operation safety. The automatic centering control of the detection wheel is the key core technology of the rail flaw detection vehicle. How to control the position of the detection wheel so that the ultrasonic wave can effectively enter the rail will directly affect the quality and effect of flaw detection. The purpose of the automatic centering control of the probe wheel is to ensure that the probe wheel is within a certain deviation range of the center of the rail, so that the joint between the probe wheel and the rail tread is co...
