Visualization direct current supply grounding device based on video image, and monitor method

Abstract

The invention discloses a visualization direct current supply grounding device based on a video image, and a monitor method. The visualization direct current supply grounding device based on the video image comprises an RTU signal processing part and a grounding transmission control mechanism connected with the RTU signal processing part. The RTU signal processing part comprises a monitor part, an image display part, a power source part, a photovoltaic conversion module and a fiber optic Ethernet channel. The monitor part can transmit measurement signals to a monitor host in real time, wherein the measurement signals comprise ground wire hanging and detaching information, the electrified state of a contact net and the like when maintenance and first-aid repair are carried out; meanwhile, the image display part is started, and the turn-on and turn-off states of a grounding separation switch are collected in real time so that working personnel in a dispatching center can determine the accuracy of the information; meanwhile, the ground wire hanging and detaching position is located, and the purpose of the reliable on-line monitor and visualization monitor is achieved. The problems that in the maintenance and first-aid repair operation of an existing rail traffic power supply system, the ground wire still needs to be mutually hung and detached, actual image information of a spot cannot be visually obtained, the spot cannot be accurately mastered, error judgments are made and error power transmission is caused can be solved.

Description

technical field [0001] The invention belongs to the technical field of electrified railway traction power supply, and in particular relates to a visual DC power supply grounding device based on video images and a monitoring method based on the device. Background technique [0002] When the power supply system along the urban rail transit and other associated systems are performing normal maintenance and emergency repairs, the method of manually hanging and removing the ground wire is generally used at home and abroad. Manually go to the pit foundation site of the power supply partition to manually connect the ground wire to the contact rail (positive pole). [0003] The procedure for manually hanging the ground wire is as follows: connect the ground wire of the electroscope to the running rail (negative pole) -> touch the positive pole of the electroscope to the contact rail (positive pole) for electrical inspection -> confirm whether the contact rail has no electricit...

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the present invention provides a visual DC power supply grounding device and monitoring method based on video images, which solves the problem that the existing rail transit power supply system maintenance and emergency repair operations still require manual installation and removal of the ground wire and cannot be obtained intuitively. The actual image information of the site cannot accurately grasp the site situation, resulting in misjudgment and wrong power transmission
