A precise positioning device and auxiliary tooling for imaging equipment of the running part

Abstract

The invention discloses a precise positioning device for imaging equipment of running parts, which includes imaging equipment, and the imaging equipment is connected with an installation frame; the installation frame is arranged under the track and is installed and connected with the track through a first suspension module; A limit module is provided, and the limit module is used to determine the horizontal position of the installation frame. Taking the track as the reference plane, set up the installation frame on the track, and then fix the imaging device on the installation frame, thus ensuring that the distance between the imaging device and the running part of the train is consistent, and it is convenient for the collected images to be processed by algorithm and improve detection accuracy. The present application also provides an auxiliary tool for the positioning device.

Description

technical field [0001] The invention relates to the field of train operation security equipment, in particular to a precise positioning device and auxiliary tooling for imaging equipment of running parts. Background technique [0002] With the continuous increase of my country's railway mileage, the importance of trains in transportation is also increasing. In order to ensure the safety of driving, the running part that carries the train running on the track needs to be inspected regularly to eliminate potential safety hazards on the running part. [0003] The current inspection method usually adopts image acquisition and recognition. The data acquisition box, including imaging equipment, trigger sensors and other components, is pre-buried on the rails. When the train passes by, the data acquisition box is triggered and takes pictures of the running part of the train, and then sends the collected images to into the backend for analysis. Using the imaging detection method,...

Problems solved by technology

[0004] The problem is that since the data collection box is directly buried in the foundation under the track, it is difficult to keep the location of the data collection box consistent

The distance between the imaging equipment and the running part in the data acquisition box is different, so that there are changes in size and angle between the pictures taken by different imaging equipment, which is not conducive to the analysis and diagnosis of the image by the image recognition algorithm at the back end, affecting the detection accuracy
