Device, system and method for detecting and monitoring suspension state of overhead line system

Abstract

The invention discloses a device, system and method for detecting and monitoring the suspension state of a contact network, and relates to the technical field of detection of a contact network suspension system.The accuracy and low time delay of rod scanning can be effectively improved through a low-delay detection module and a threshold value judgment module; the signal filtering module and the interference filtering module are used for carrying out efficient real-time signal analysis, and a detection technology adaptive to various interference scenes is adopted, so that all-weather real-time low-delay detection of the overhead line system suspension state detection and monitoring device can be ensured, and a shot overhead line system image is prevented from deviating from the center of a view field.

Description

technical field [0001] The invention relates to the technical field of catenary detection, in particular to a detection and monitoring device, system and method for the suspension state of a catenary. Background technique [0002] The traditional trigger judgment method of catenary suspension state detection and monitoring device adopts laser to emit light vertically upwards, and high-speed camera is used for real-time analysis to detect any one of pillar, locator, locator support, etc. to generate a trigger signal, and immediately generate a synchronous signal to distribute to the camera and supplementary lights. Because image analysis and data filtering process take a lot of time, especially in the case of complex scenes, the calculation time is increased, which will cause untimely triggering, so that the detected catenary image will deviate from the center of the field of view, or even exceed the scope of the field of view . In addition, the camera acquisition technolog...

Problems solved by technology

Because image analysis and data filtering process take a lot of time, especially in the case of complex scenes, the calculation time is increased, which will cause untimely triggering, so that the detected catenary image will deviate from the center of the field of view, or even exceed the scope of the field of view

In addition, the camera acquisition technology is easily disturbed by flying insects, birds, and high and low tunnel scenes. Therefore, a low-latency, high-accuracy trigger detection technology is urgently needed. The trigger technology of the image acquisition module for the detection of catenary suspension status
