Power line sound wave loading device and method based on sound wave positioning

Abstract

The invention relates to the technical field of power line protection, in particular to a power line sound wave loading device and a method based on sound wave localization, and the sound wave localization method comprises the following steps: firstly, obtaining a plurality of modulated waves, then analyzing the modulated waves to obtain a vibration source position and a wave generation moment, and then, according to the wave generation moment and the vibration source position, obtaining a plurality of modulated waves; according to the embodiment of the invention, sound waves are used as carriers, the transmission speed of the sound waves is relatively stable, and the transmission speed of the sound waves is slower than that of electromagnetic waves and light waves, so that under the condition of the same time precision, the transmission speed of the sound waves is relatively stable, and the transmission speed of the sound waves is lower than that of the electromagnetic waves and the light waves. The positioning precision is far higher than that of a carrier using electromagnetic waves or light waves, the requirements of most engineering surveying can be met, mechanical waves are used as the carrier, the power line cannot be damaged, transmission of electric signals cannot be affected, and use is safer.

Description

technical field [0001] The invention relates to the technical field of power line protection, in particular to a power line sound wave loading device and a method based on sound wave positioning. Background technique [0002] Power supply line protection area refers to the protection area planned to ensure the safety of power supply lines. [0003] Taking China as an example, in order to ensure the smooth progress of power production and construction, and effectively maintain the public and personal safety around the line, in accordance with the relevant requirements of Article 10 of the "Regulations on the Protection of Electric Power Facilities" on the protection of power lines, the wire edges extend horizontally to the outside and vertically. In the area within the two parallel planes formed by the ground, the extension distance of the sidelines of the voltage conductors at all levels in general areas is as follows: 1-10 kV is 5 meters, 35-110 kV is 10 meters, 154-330 kV ...
