Embodiment Construction
[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0038] The application provides a catenary error detection method, which can be applied to a catenary error detection vehicle. Wherein, the catenary error detection vehicle at least includes: a detection vehicle body, a data processing device and an ultrasonic sensor. Among them, the ultrasonic sensor obtains the position coordinates of the detection vehicle body relative to the rail during the operation of the catenary error detection vehicle based on the sensor coordinate system, and sends the collected position coordinates to the data processing device; then, the data p...

The application relates to a catenary error detection method and an error detection vehicle. The catenary error detection vehicle at least includes: a detection vehicle body, a data processing device and an ultrasonic sensor, and the method includes: the ultrasonic sensor, based on the sensor coordinate system, obtaining the position coordinates of the detection vehicle body relative to the rail during the operation of the catenary error detection vehicle, And the collected position coordinates are sent to the data processing device; the data processing device processes the position coordinates based on the static datum coordinate system, and obtains the error offset of the position coordinates relative to the static datum coordinate system, so that according to the error offset, The catenary detection parameters obtained by the catenary error detection vehicle are compensated. By adopting the method, the error compensation of each detection parameter of the catenary can be realized.
Description
technical field [0001] The present application relates to the field of catenary technology, in particular to a catenary error detection method and an error detection vehicle. Background technique [0002] With the development of catenary detection technology, there has been a technology to detect the catenary by using the detection vehicle. The detection equipment on the detection vehicle can obtain the geometric parameters and pantograph-catenary relationship between the pantograph and the catenary in real time during the driving process of the detection vehicle. Parameters and auxiliary parameters and other detection parameters, and the detection parameters are fed back to the operation and maintenance department in real time, and the operation and maintenance department calculates each detection parameter to complete the operation and management of the catenary. [0003] The testing car will vibrate randomly (shaking head, nodding, stretching, ups and downs, rolling and s...
