Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. When the above-mentioned device is in use, the electromagnetic eddy current detection sensor needs to be pasted and fixed on the vertical side where the tip of the switch point rail is closely attached to the base rail, and the installation process requires a lot of professionals. The installation efficiency is low due to personnel construction and equipment status adjustment; 2. The electromagnetic eddy current detection sensor in the above device is fixedly installed on the switch point rail. When the point rail is damaged and deformed, the electromagnetic eddy current detection sensor will also be affected. Cause damage and failure, and it is not easy to disassemble for secondary use, and the cost of use is high

Abstract

The invention discloses a turnout switch point closeness detection method based on an image detection technology. The method comprises the following steps: identifying a switch point: tracking the switch point; identifying a fork tip edge; and comparing the fork tip motion trail with the normal motion trail, and carrying out fork tip closeness state detection. The invention provides the turnout junction point closeness detection method based on the image detection technology, non-contact real-time nondestructive detection of turnout junction closeness is realized, the detection efficiency andaccuracy are high, and the turnout junction point closeness detection method is fast and efficient and is very worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a method for detecting closeness of turnout tips based on image detection technology. Background technique [0002] The closure between the switch point rail and the basic rail is a key factor related to traffic safety. When the closure gap between the point rail and the basic rail exceeds 2-4mm, it will cause a train accident. Therefore, it is necessary to carry out daily repair and maintenance on the point rail of the turnout. For the inspection of the point rail and the basic rail, the manual inspection method is time-consuming and laborious. Coupled with the increasingly busy high-speed railways and freight lines in my country, the skylight time for railway maintenance is getting more and more However, the fixed-period maintenance and post-failure repair mode adopted by the current electricity and public works departments is increasingly difficult to meet the n...
