[0022] In this embodiment, as shown in the attached Figures 1-6As shown in the figure, a catenary geometric parameter detection device includes a catenary geometric parameter detection module 1, a vehicle-mounted detection host 2, and a vehicle body vibration compensation module 3. The catenary geometric parameter detection module 1 is composed of a geometric parameter detection beam 7. A flexible catenary detection camera 4 is arranged at the left end of the geometric parameter detection beam 7. A rigid catenary detection camera 5 is arranged on the right side of the flexible catenary detection camera 4. A laser 6 is arranged at the right end of the geometric parameter detection beam 7.

[0023] Further, the catenary geometric parameter detection module 1 is installed on the roof center line through bolts.

[0024] Further, it also includes a flexible catenary detection camera 4, a rigid catenary detection camera 5, and an installation base 8 is also arranged at the bottom of the laser 6.

[0025] Further, the vehicle body vibration compensation module 3 is composed of a vibration detection beam 12. Two equipment inlet holes 11 are arranged symmetrically side by side at the center of the vibration detection beam 12. A left vehicle body vibration compensation device 9 is arranged at the left end of the vibration detection beam 12. A right vehicle body vibration compensation device 10 is arranged at the right end of the vibration detection beam 12. An electronic tag reader 13 is arranged at the lower end of the center of the vibration monitoring beam 12.

[0026] Further, the angles set by the left vehicle body vibration compensation device 9 and the right vehicle body vibration compensation device 10 should ensure that there is no visual field obstruction between the compensation devices and the track within a certain range.

[0027] Further, it also includes a vehicle-mounted detection host 2. A host power switch button 14, a storage hard disk compartment 15, no less than 4 M12 power output interfaces, no less than 3 M12 network interfaces, and no less than 1 host power input interface are arranged on the vehicle-mounted detection host 2.

[0028] The detection principle of the catenary geometric parameter detection module 1 is as follows:

[0029] As the vertical and horizontal spatial positions of the contact wire are different, the position of the distorted curve (at the position of the red circle) formed by the line laser hitting the contact wire in the image is also different. By using professional image processing algorithms, the pixel coordinates of the bottom of the contact wire in the image are found, and then through a series of coordinate system calculations, the geometric position of the contact wire in the actual space, that is, the wire height and the pull-out value, are obtained.

[0030] The working principle of the vehicle body vibration compensation module 3 is as follows:

[0031] A non-contact measuring device that adopts the laser light section measurement principle based on machine vision. A compensation measuring device is installed on both sides of the bottom of the vehicle body. The line laser irradiates the rail profile from the side at a certain angle, and the camera collects the distorted laser image of the rail. The measurement computer analyzes and processes it, and uses image processing algorithms to calculate the offsets of the rail in the vertical and horizontal directions relative to the vehicle body. Then, the measurement results of the catenary geometric parameters are corrected through a compensation algorithm.

[0032] The beneficial effects of the present utility model: By adopting a non-contact detection method, the device is installed on the inspection vehicle, and the rapid detection of the catenary geometric parameters can be completed during the vehicle driving process. At the same time, a vehicle body vibration compensation device is configured, which can greatly improve the detection accuracy. This device solves the problems of large workload, low efficiency, and long time consumption of traditional manual work, greatly reduces the labor intensity of on-site workers, improves the efficiency of the detection work, and provides a guiding basis for the maintenance of the catenary.
