Power cable intelligent monitoring system based on unmanned aerial vehicle

Abstract

The invention discloses a power cable intelligent monitoring system based on an unmanned aerial vehicle. The system comprises a video image module, a positioning module, a path calculation module, a first controller, a video image module, a second controller, a signal adjustment module, and a monitoring terminal. If the position difference between position information B and position information A is greater than 10m, the first controller gives priority to the position information B, sends the position information B into the second controller and corrects the positioning position deviation of the positioning module, namely, the positioning position information A of the positioning module is corrected into a position signal B, positioning is started again, and a triode Q2 and capacitors C4 and C7 are used for forming an oscillating circuit to improve the signal frequency; LC oscillation consumption is compensated, and meanwhile, an operational amplifier AR3 is used for comparing an output signal of the operational amplifier AR2 with a data reference signal, and if attenuation of the output signal of the second controller is too large, a silicon controlled rectifier Q1 is triggered to be on, so the effect of compensating the signal is realized.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to an intelligent monitoring system for power cables based on an unmanned aerial vehicle. Background technique [0002] With the needs of urban modernization and the development of power technology, cables in large cities in my country are divided into high-altitude cables and underground distribution networks, while the environment of underground distribution networks is more complicated, and cables are often caused by natural aging, corrosion or small animals. In addition, due to the large amount of heat generated during the cable work process, the cable protective layer releases a large amount of harmful gases at high temperatures; water seepage occurs in the cable tunnel due to the impact of the environment, and the high temperature and water seepage of the cable tunnel have a great impact on inspections. The safety and health of personnel are endangered; [0003] Therefore, t...

Problems solved by technology

[0002] With the needs of urban modernization and the development of power technology, cables in large cities in my country are divided into high-altitude cables and underground distribution networks, while the environment of underground distribution networks is more complicated, and cables are often caused by natural aging, corrosion or small animals. In addition, due to the large amount of heat generated during the cable work process, the cable protective layer releases a large amount of harmful gases at high temperatures; water seepage occurs in the cable tunnel due to the impact of the environment, and the high temperature and water seepage of the cable tunnel have a great impact on inspections. The safety and health of personnel are endangered;

[0003] Therefore, the UAV-based power cable intelligent monitoring system is being vigorously developed. UAVs are used to inspect the cable tunnel to inspect the environment in the tunnel, locate the fault location, and reduce the occurrence of cable disasters. However, for some lake bottom or deep Underground cable tunnels in rivers can be tens of meters deep and thousands of meters long, and the lake or river water above the cable tunnel will greatly reduce the signal penetration, that is, the signal transmission attenuation is serious, which is easy to cause The positioning of drone inspection operations is not accurate, and even the fault image information cannot be accurately transmitted to the monitoring system terminal
