Abstract

The invention provides a dynamic measurement method, device and system for track settlement and deviation. The measuring method comprises the following steps: acquiring a track profile curve picture; in the track profile curve picture, selecting an arc-shaped highest point on a track profile curve as a center, and intercepting a pixel template; calculating the pixel position of the pixel template in the track profile curve picture through template matching; converting according to the pixel position to obtain the actual space physical position coordinate of the pixel template; and calculating the offset and settlement of the orbit according to the change of the actual space physical position coordinate. According to the system, the monitoring result is transmitted in real time, and the measurement of the pull-out lead height value of the contact line is compensated. And the measured data compensates the measured value of the non-contact pull-out lead height, so that the accurate space physical coordinate of the contact line is obtained.

Description

technical field [0001] The invention relates to the technical field of catenary detection, in particular to a dynamic measurement method, device and system for track settlement and deflection. Background technique [0002] In the electrified track, the transmission line erected along the rail is called the catenary, and its function is to directly transmit the electric energy obtained from the traction substation to the electric locomotive for use. The electric locomotive draws current through direct contact between the pantograph installed on the roof and the catenary wire. In order to ensure that the locomotive can obtain a continuous and stable current, the pantograph and the contact wire must be in reliable contact. Therefore, the quality and geometric parameters of the catenary will directly affect the transportation capacity of the electrified railway. With the increase of the train speed, the requirements for the contact suspension are getting higher and higher, so th...
