Power transmission line online inspection flight monitoring system

Abstract

The invention discloses a power transmission line online inspection flight monitoring system comprising an inspection command car and an aircraft; the inspection command car moves along a fixed powertransmission line, and controls the aircraft to move in certain assigned area; a remote transmit-receive device, a command operation system, a wireless data video image acquisition system, a generatorand a computer are arranged in the inspection command car; the remote transmit-receive device controls the aircraft to transmit the data gathered in a preset time period to the wireless data acquisition system; the wireless data acquisition system receives the aircraft data and transmits same to the computer. The system uses a redundancy determination mode to determine a power transmission line fault generation position and an aircraft deviation position, and the determination mode is accurate; the system uses field video taking mode to determine fault positions; the video data can be processed by a digital determination mode, and the determination can be done in a direct image contrast mode; the determination modes are more directly.

Description

technical field [0001] The invention relates to the technical field of monitoring and control of power transmission lines, in particular to an online inspection and flight monitoring system for power transmission lines. Background technique [0002] In recent years, with the development of the power system, the total length of high-voltage transmission lines in my country has continued to increase, and the coverage has continued to expand. In order to ensure the safety of transmission lines and their equipment, the daily inspection of power system transmission lines is an important link. However, the manual inspection of high-voltage transmission lines has a large workload and high inspection cost, and the difficulty of manual inspection will be greatly increased in complex geographical environments and harsh weather conditions; although helicopter inspections can improve the efficiency of inspections, they have a significant impact on climate conditions and geographical envi...

Problems solved by technology

However, these status monitoring systems are limited by specific monitoring targets and monitoring methods are limited, so it is difficult to fully and accurately reflect the line operation status, cannot meet the requirements of line inspection, and it is difficult to expand functions; on the other hand, these monitoring systems are limited by GPRS or CDMA Information and communication technology has shortcomings such as small transmission data capacity, poor security and reliability, and cannot meet the real-time monitoring requirements of the state quantities required for line inspections.

Since these line status monitoring systems are out of touch with tasks such as daily inspections of transmission lines, the utilization rate is not high and the economic benefits are low
