A modular electric power monitoring system and its control method based on unmanned aerial vehicles

Abstract

The invention relates to an unmanned-aerial-vehicle-based modularized power monitoring system and a control method thereof. The system comprises more than one unmanned aerial vehicle, a monitoring unit and a ground operation checking control center. The monitoring unit consists of an airplane parking area erected on a grid tower, a control module arranged on the airplane parking area, an image acquisition module, an environment monitoring module and a wireless communication module, wherein the image acquisition module, the environment monitoring module and the wireless communication module are connected with the control module electrically. A plurality of wedge-shaped grooves are formed in the airplane parking area; the control module, the image acquisition module, the environment monitoring module and the wireless communication module are arranged in the corresponding wedge-shaped grooves respectively. The monitoring unit, the unmanned aerial vehicles, and the ground operation checking control center carry out mutual data communication by the wireless communication module. According to the invention, the system and method have the following beneficial effects: with combination of unmanned-aerial-vehicle polling and the airplane parking area arranged at the grid tower, the modules are embedded into the airplane parking area to monitor power transmission in real time; and the operating states of the power cable and the tower on the power transmission line as well as the surrounding situation of the tower can be obtained without any manual field operation.

Description

technical field [0001] The invention relates to the fields of unmanned aerial vehicle technology, power grid operation inspection and maintenance technology, and electric power monitoring technology, and in particular to an unmanned aerial vehicle-based modular electric power monitoring system and a control method thereof. Background technique [0002] With the rapid development of the economy, the society's demand for electric power has increased sharply, and the requirements for power quality have continued to increase. Reduced the workload of transmission line inspection and maintenance. The power cables and towers in the transmission line are exposed to the open air for a long time, and are affected by natural factors and human factors, which increases the difficulty of inspection and maintenance of the transmission line. [0003] In order to meet the safety and stability requirements of the power system, grasp the operation status of the transmission line and eliminate...

AI Technical Summary

Problems solved by technology

In most areas of the country, manual inspection and maintenance of transmission lines is carried out by means of cooperation with helicopters. This method not only has high work intensity, poor working environment conditions, and low work efficiency, but also has risks for personal safety, and some lines are caused by terrain factors. Difficult or even impossible to carry out inspection and maintenance

However, manned helicopters are restricted by factors such as aviation control, weather, and operating costs, so they cannot search for accidents and abnormalities in a timely manner.

At the same time, the monitoring of the power grid by the power sector is mainly concentrated in substations and distribution stations. The monitoring of transmission lines is still at the stage of regular manual inspections. It is impossible to grasp the operation status of transmission lines and the surrounding environment in real time, and it is impossible to find out the location of fault points in time. and failure causes, resulting in low efficiency of line inspection and maintenance

Every year, due to tree and bamboo barriers, lightning damage, external force damage and other reasons, there will be multiple line trip failures in the operation of the line, which will also reduce the quality of power supply virtually.
