Abstract

The invention provides a conductor sag monitoring device based on laser distance measurement. The monitoring device comprises a laser distance measurement sensor hung on a conductor. The laser distance measurement sensor is used for measuring the distance between the conductor and the ground. The monitoring device can further comprise an angle sensor, the angle between a laser pulse and a perpendicular line perpendicular to the ground is measured through the angle sensor, and the perpendicular distance between the conductor and the ground is calculated. The invention further provides two methods for using the conductor sag monitoring device based on the laser distance measurement. The distance between the conductor and the ground and the conductor sag are measured with the laser distance measurement methods, the measurement accuracy is high, the implement methods are simple, and the collected data are accurate and reliable.

Description

technical field [0001] The invention relates to a wire sag monitoring device based on laser distance measurement. [0002] The invention also relates to two monitoring methods using a wire sag monitoring device based on laser distance measurement. Background technique [0003] Conductor sag refers to the vertical distance between the lowest point of the conductor and the line between the two suspension points when the suspension height of the conductors on two adjacent poles is the same on a flat ground; Similarly, at this time, there will be two sags within a span, that is, there are two vertical distances from the two suspension points of the wire to the lowest point of the wire, which are called the maximum sag and the minimum sag. The position where the maximum sag occurs depends on the specific circumstances, among which the common maximum sag of the wires between adjacent towers with a height difference of no more than 10% appears in the center of the span. From the ...
