Overhead line standard picture library collection device and working method thereof

Abstract

The invention provides an overhead line standard picture library collection device and a working method thereof. The device and the method are applied to a hand-push type inspection vehicle. The hand-push type inspection vehicle is operated on a railway in a construction phase. The collection device comprises a photographing device, a storage module and a triggering device. The triggering device comprises at least two laser radars. The laser radars are arranged at front and rear ends of an advancing direction of the inspection vehicle and are used for outputting triggering signals when it is inspected that the distance between an overhead line support post and the inspection vehicle is equal to a preset threshold value. The photographing device comprises a plurality of photographing modules. The photographing modules are arranged at the front and rear ends of the advancing direction of the inspection vehicle, are connected with the triggering device and are used for photographing pictures of both sides of overhead line components according to the triggering signals. The storage module is connected with the photographing device and is used for storing the pictures of both sides of the overhead line components.

Description

technical field [0001] The invention relates to the field of catenary image collection, in particular to a catenary standard image library collection device and a working method thereof. Background technique [0002] The catenary is a complex system including contact suspension, positioning support device, compensation device and other structures. In the operation and maintenance of the catenary, the "missing, loose, detached, and broken" faults of the catenary components account for a large part of the catenary safety hazards. For a high-speed railway catenary, due to the increase in the tension of the catenary wire and the catenary cable, the force and vibration of each catenary component will also increase significantly, and the safety of the catenary components will be more prominent. [0003] The existing catenary 4C device is a detection device that intelligently analyzes and processes image data and automatically identifies the abnormal appearance of parts; however, a...

[0003] The existing catenary 4C device is a detection device that intelligently analyzes and processes image data and automatically identifies the abnormal appearance of parts; however, automatic identification of catenary images is not easy, and catenary 4C devices involve many types of parts , and the types of defects of each component are various, but in reality catenary component defects are rare, and the image data covering component defects is even rarer, which has great impact on the algorithm research and recognition performance test of automatic image recognition. a big obstacle
