Pantograph-catenary high-temperature interference identification and detection method

Abstract

The invention discloses a pantograph-catenary high-temperature interference identification and detection method. The infrared camera installed on the rail transit train acquires continuous infrared images, calculates the maximum temperature value and its position coordinates in each frame of infrared images, and then, according to four One or more combinations of the three judging conditions are used to identify and judge whether the maximum temperature value in the infrared image is high temperature interference. The invention can analyze infrared images in real time, identify high-temperature disturbances such as the sun and the moon, reduce the false alarm rate of pantograph-catenary high-temperature defect alarms, reduce the redundancy of false alarm data, and improve the accuracy and effectiveness of high-temperature defect alarms.

Description

technical field [0001] The invention relates to the field of catenary, in particular to a pantograph-catenary high-temperature interference identification and detection method. Background technique [0002] The catenary is a high-voltage transmission line erected in a "zigzag" shape along the sky above the rails in the electrified railway for pantographs to take current. The catenary is the main frame of the railway electrification project, and it is a special form of transmission line erected along the railway line to supply power to the rail vehicles. Generally, it is composed of contact suspension, support device, positioning device, pillar and foundation. [0003] The development of electrified railway is an inevitable trend of railway modernization. The pantograph-catenary operating state safety monitoring system for electrified railway is mainly to detect the pantograph-catenary contact state. When defects such as bowing and pantograph gaps occur, the temperature of...

Problems solved by technology

[0004] However, since the image collected by the infrared camera is not a single pantograph and catenary image, its background is quite complicated, such as the sun, the moon and other objects that emit light and heat by themselves will exist in the image, so it will cause the generated high temperature alarm Data contains a large number of false alarms

And these invalid alarm data will have the following impact: when using wireless transmission technology to transmit back to the data terminal, it will consume a lot of traffic, and the staff will have to manually analyze and process the data again, which will increase the workload
