Contact network flaw detection system

Abstract

The invention discloses a contact network flaw detection system, which comprises a laser imaging radar, an X-ray emitter, a voltage booster, an X-ray receiver and a control circuit board, wherein the laser imaging radar emits a laser beam to a contact line for scanning, laser radiation reflected by the contact line is received to generate continuous analog signals, the continuous analog signals are restored into a real-time contact line image, the height of the contact line in the horizontal direction is calculated after the analog signals are converted into digital signals in a control circuit board, then the abrasion degree of the outer surface of the contact line is determined, the electric energy obtained by a pantograph on the contact line is boosted by the booster and then is supplied to the X-ray emitter, the X-ray emitter and the X-ray receiver form the X-ray flaw detector, flaw detection is conducted on the interior of the contact line, the damaged contact line is positioned through a Beidou positioning module, and then detected information is transmitted to a monitoring center of related departments of a railway and a train running on the line in real time through a 5G communication technology.

Description

technical field [0001] The invention relates to the field of catenary flaw detection, in particular to a catenary flaw detection system. Background technique [0002] The contact wire is a high-voltage pre-tensioned wire erected along the electrified railway, and its material is usually pure copper, copper-silver alloy, copper-magnesium alloy and copper-tin alloy. During the operation of the train, the pantograph sliding plate installed on the top of the locomotive slides through contact with the contact wire, and transmits the obtained electric energy to the power supply system of the electric locomotive as the driving force for its high-speed operation. This process is also called receiving current. The quality and stability of the flow directly determine whether the electric locomotive can run safely and reliably. The pantograph-catenary system composed of pantograph and contact wire constitutes an important power supply system of electrified railway. [0003] The caten...
