Compensation capacitor defect detection method and device

Abstract

The embodiment of the invention provides a compensation capacitor defect detection method and device. The method comprises the following steps: acquiring current state data of a target compensation capacitor; determining the current environment temperature of the area where the target compensation capacitor is located, the current mains supply condition and a standard visual image corresponding to the target compensation capacitor according to the acquisition position; determining a current correction parameter according to the current environment temperature and the acquisition position; determining the deformation condition of the target compensation capacitor according to the current visual image, the current mains supply condition, the current correction parameter, the acquisition position and the standard visual image; specifically, determining an image difference value according to the current visual image and the standard visual image; and generating the deformation condition according to the current correction parameter and the image difference value. Interference on driving caused by people on the road is reduced, and the probability of occurrence of personal casualty accidents is reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a compensation capacitor defect detection method and device. Background technique [0002] The compensation capacitor in the non-insulated track circuit system is used to realize the electrical isolation between adjacent track circuits, to ensure the effective transmission of signals in this section, and to achieve the balance of power frequency traction return, which is very critical in the non-insulated track circuit system component. At present, the non-insulated track circuits used in my country's large railway lines are generally tuned non-insulated track circuits. [0003] The compensation capacitance detection method based on vision technology mainly adopts the manual inspection method. The inspectors not only have to walk dozens of kilometers at night, but also inspect the signal equipment. The inspection cycle is half a year and one month. [0004] However, th...

[0004] However, the manual inspection method is labor-intensive and the inspection cycle is long. Once the equipment in the section is damaged, it is not easy to find it in time, and it will increase the interference of people on the road and increase the probability of personal injury and death accidents.
