Abstract

The present invention relates to a system and method of continuously tracking and measuring the geometrical parameters of an overhead line system. The system comprises a dolly body capable of walking along a steel rail, and a measuring device and an industrial computer which are arranged on the dolly body. The measuring device is installed on the dolly body via a rotary motor and comprises an industrial camera and a laser range finder, the optical axis direction of the industrial camera and the laser emergent direction of the laser range finder are arranged parallelly, the industrial camera real-timely shoots the images of the overhead line systems above the rail and sends to the industrial computer, and the industrial computer obtains the position deviation of the emergent laser of the current laser range finder and the overhead line system, utilizes the position deviation to generate a driving signal to send to the rotary motor, and controls the rotary motor to drive the measuring device to act, so that the emergent laser of the laser range finder always irradiates to the detected overhead line system during the walking process of the dolly body, and then the laser range finder obtains the geometrical parameters of the overhead line system directly.

Description

technical field [0001] The invention relates to a system and method for continuously tracking and measuring geometric parameters of catenary. Background technique [0002] The catenary is a high-voltage transmission line erected in a "zigzag" shape along the sky above the rails in the electrified railway for pantographs to take current. The catenary is the main frame of the railway electrification project. It is a special form of transmission line erected along the railway line to supply power to the electric locomotive. Operation is critical. As my country's railway speeds up, the "skylight" time for detecting and repairing faults is getting shorter and shorter, which puts forward higher requirements for the efficiency of catenary detection equipment. [0003] At present, the hand-held catenary measuring instrument is widely used, and the point-to-point laser measurement method is used to measure the geometric parameters such as the conductance and pull-out value of the c...
