Abstract

The invention relates to power transmission line tower stress monitoring equipment, in particular to a power transmission line tower stress monitoring device. The power transmission line tower stress monitoring device solves the problem that a mature power transmission line tower stress monitoring device is unavailable at present. The power transmission line tower stress monitoring device comprises a main control computer, a solar power generation device and a wind power generation device providing power for the main control computer, JHBU-T pressure sensors arranged on the bottom of each supporting frame of a tower, and a monitoring center PC in wireless communication with the main control computer, wherein the main control computer comprises a computer case, an STC90C516RD single-chip microcomputer is arranged in the computer case, the output end of each pressure sensor is connected with the input end of the single-chip microcomputer, an SIM900A GPRS transmitter module is connected to the output end of the single-chip microcomputer, and a GPRS receiving module is arranged on the monitoring center PC. The power transmission line tower stress monitoring device can well monitor the stress condition of the power transmission tower in real time so that corresponding remedies can be made, severe economical losses are avoided, and safety and high efficiency of power supply are guaranteed.

Description

technical field [0001] The invention relates to a stress monitoring device for a power transmission line tower, in particular to a power transmission line tower stress monitoring device. Background technique [0002] Today, with my country's rapid economic growth and increasingly tense energy sources, the safety of power transmission towers has received more and more attention. Transmission line towers are an important part of the power grid system. In the wild environment, they are easily affected by natural disasters such as strong winds and rainstorms, causing various accidents. In recent years, various accidents of transmission poles and towers have occurred frequently. The tower lodging phenomenon caused by wind speed and direction, wire tension, geological goaf and other environmental factors has seriously affected the normal operation of the power grid and caused huge economic losses. Monitoring the stress status of towers is of great significance to ensure the safe ...
