Double-band imaging discharge detector for high-speed train, and application method of double-band imaging discharge detector

Abstract

The invention discloses a double-band imaging discharge detector for a high-speed train, and an application method of the double-band imaging discharge detector. The detector comprises a visible light lens, a visible light camera, an ultraviolet lens, an ultraviolet camera, and a processing and control board, and a power board. The detector is installed behind a pantograph of the roof of a locomotive. The visible light camera matched with the visible light lens obtains visible light background images of the pantograph and an overhead line system in front of the locomotive, and transmits the images to the processing and control board. The ultraviolet camera matched with the ultraviolet lens and a filter obtains the ultraviolet target images of the pantograph and the overhead line system in front of the locomotive, and transmits the images to the processing and control board. The processing and control board carries out the image processing, and judges whether the key parts of the pantograph and the overhead line system perform partial discharge and whether the pantograph and the overhead line system generate arcs or not, and carries out the positioning and displaying of video images when the partial discharge happens or the arcs are generated. The detector can timely find out the partial discharge conditions, detects the arc state in real time, and reduces the unnecessary economic loss in order to guarantee the normal transportation order of the high-speed train.

Description

technical field [0001] The invention relates to the field of photoelectric detection, in particular to a dual-band imaging discharge detector for high-speed rail and its application method. Background technique [0002] When the high-speed rail locomotive is running, the required current is obtained from the high-voltage contact line through the pantograph at the top of the locomotive. When the two are in good contact, the voltage of the two is equal. However, when the pantograph is lifting the bow to take the current, due to the hard point of the catenary, the vibration of the catenary (pantograph head), the sudden change of conductance, the freezing of the catenary (pantograph), the corrosion of the catenary, etc. The electrical contact between the "bow-net" is unreliable, and the "bow-net" will go offline. An arc will be generated when the train is offline. The higher the train speed, the greater the probability of being offline, and the greater the arc will be. How to ...

Problems solved by technology

[0003] Moreover, high-speed rail line inspections mainly use manual inspections or special-purpose locomotive visible light imaging inspections. After processing, sometimes manual participation in analysis and positioning is required, which is troublesome
