Abstract

The invention relates to an overhead transmission line crossing distance online measurement method, which belongs to the technical field of laser ranging, and aims to solve the problems in the prior art. The method comprises the following steps that 1, a manually set swing range is inputted into an information processor; 2, the information processor controls a motor driver according to a manually set swing range, so that the motor driver drives a swing motor to continuously swing back and forth in the set range and drives a laser range finder to continuously swing back and forth, and the laser range finder scans the crossed unsafe area of the overhead transmission line; 3, a light beam emitted by the laser range finder is projected to a certain power transmission line to generate reflected light, a range finding value d1 is given, and a swing angle value recorded by the encoder at the moment is alpha1; when the light is projected to another power transmission line, reflected light is generated, a distance measurement value d2 is given, and a swing angle value recorded by the encoder at the moment is alpha2; 4, according to cosine theorem, the information processor calculates crossing distance of the transmission line;.

Description

technical field [0001] The invention belongs to the technical field of laser distance measurement, and in particular relates to an on-line measurement method for crossover distances of overhead power transmission conductors. Background technique [0002] In recent years, with the rapid development of the economy and the continuous expansion of the transmission radius and scope of the transmission and distribution network, the path of the transmission line has become more and more complicated, and the phenomenon of transmission lines passing through areas with complex terrain or erecting multiple lines in the same corridor is increasing. , so that the phenomenon of overhead transmission lines crossing is becoming more and more common. Although the distance to the ground required by the regulations is met during the construction of the transmission line, with the long-term operation of the overhead transmission line, there will be some reasons that cause the distance of the co...
