Online image detecting device and method for operation state of onboard pantograph of train

Abstract

The invention discloses an online image detecting device for an operation state of an onboard pantograph of a train. The online image detecting device comprises an industrial camera, a fill-in light,an onboard antenna, an onboard display and an onboard processing host unit; the industrial camera is responsible for video image acquisition; and the fill-in light enhances pantograph area brightness;the onboard antenna realizes wireless communication; the display displays videos; and the onboard processing host unit comprises an image processing module, a data transmission module, a data storagemodule and a power control module. A method of the online image detecting device is further provided. The industrial camera captures video images and transmits the video images to the onboard processing host unit in real time; the format is converted through video encoding, so as to process videos by an online image detecting method for pantograph sliding plate wear; meanwhile, subtitles are superposed to display the operation state of the pantograph through the videos on the display; and the onboard antenna sends data and messages to a ground data processing center through the wireless communication. The online image detecting device disclosed by the invention is easy and convenient to detect, high in precision and high in stability, meets requirements for overhauling a pantograph sliding plate, and can provide a reference for detecting a state of a rail transit vehicle.

Description

technical field [0001] The invention belongs to the technical field of on-line detection of urban rail transit trains, and in particular relates to an on-line image detection device and method for the running state of a pantograph mounted on a train. Background technique [0002] The pantograph carbon slide is an important current-collecting component in the electrified vehicle power supply system. It is installed on the uppermost part of the vehicle pantograph, directly in contact with the power supply network line, and guides the current on the power supply network in a static or sliding state, and transmits it to the Vehicle power supply system to maintain the normal operation of the vehicle. During the operation of the vehicle, the service life of the carbon skateboard of the existing structure is mainly determined by several factors such as the net wear of the carbon skateboard, the pull-out value of the power supply network line, and the dynamic cooperation factors bet...

AI Technical Summary

Problems solved by technology

Manual detection needs to be carried out when parking and the accuracy is not high, which has great limitations; the sensor detection of slide wear may interfere with the operation of the pantograph, the device is relatively complicated, the feasibility is not high, and the efficiency is poor; non-contact image detection is The most feasible detection method

At present, the research on dynamic detection systems and devices for pantograph-catenary operating status in urban rail transit is in the ascendant, but none of them involve online detection of pantograph slide wear
