Measurement method of conductance value of monorail contact line

Abstract

The invention provides a single-track contact line conductor height measurement method. The method comprises providing a measurement device installed on a train, reading measurement parameters of the measurement device in an initial state, wherein the measurement device comprises a line laser displacement sensor corresponding to a zone where a contact line is arranged, a first point laser displacement sensor installed above the line laser displacement sensor, and a second point laser displacement sensor installed below the line laser displacement sensor, and measuring a conductor height value of the contact line in train operation. Through the line laser displacement sensor installed on the train, height of the relative device of the contact line is measured in real time, and through the first point laser displacement sensor and the second point laser displacement sensor, inclination correction is realized. The single-track contact line conductor height measurement method realizes real-time measurement of a conductor height of a contact line, prevents train conductor height-caused fault and provides favorable data for contact line maintenance.

Description

technical field [0001] The invention relates to a monitoring and measuring method for a monorail train, in particular to a method for measuring the conductance value of a monorail contact line. Background technique [0002] The monorail locomotive receives current through the pantograph from the grid of the track girder, which consists of contact wires. Faults sometimes occur between the pantograph and the grid, and the relationship between the pantograph and the grid directly affects the safe operation of the train. Existing pantographs do not monitor at all when they are in contact with the power grid during actual operation. They can only be monitored after the train returns to the depot, so that the failures that will occur cannot be effectively prevented. [0003] The height of the contact line on the monorail track beam relative to the running surface of the track beam is called the guide height value in the industry (because the track beam running surface is a vertic...

AI Technical Summary

Problems solved by technology

The existing pantograph has no monitoring at all when it is in contact with the power grid in actual operation, and can only wait for the train to return to the depot for monitoring, so that it cannot effectively prevent future failures

[0003] The height of the contact line on the monorail track beam relative to the running surface of the track beam is called the guide height value in the industry (because the track beam running surface is a vertical surface, the guide height value is the horizontal distance between the contact line and the track beam running surface) , the conductance value of the contact wire is designed within a certain range. Once the conductance value exceeds the normal range, it is easy to cause faults such as pantograph off-line, arcing, and bowing, which will greatly affect the safety of the train.
