Power transmission line inspection system based on power transmission line pole

Abstract

The invention provides a power transmission line inspection system based on a power transmission line tower pole. The power transmission line inspection system comprises tower pole nodes, a power transmission line monitoring system deployed on a cloud computing platform, an unmanned aerial vehicle ground station and an unmanned aerial vehicle. According to the invention, the cruising route of theunmanned aerial vehicle is divided into a plurality of sub-paths through the tower pole nodes, each time the unmanned aerial vehicle completes image acquisition of one sub-path, the collected images are transmitted to the corresponding tower pole node for foreign matter detection, and the detection result is reported to a power transmission line monitoring system; then, the unmanned aerial vehicleempties the stored images, and the environment image of the next sub-path is acquired again; and if the identification result reported by a certain tower pole node is that the foreign matter exists,the power transmission line monitoring system can quickly determine the power transmission line section where the foreign matter appears according to the tower pole node position of the reported foreign matter and the previous tower pole node position.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance, in particular to a power transmission line inspection system based on transmission line towers. Background technique [0002] my country has a vast territory and intersects mountains, rivers and plains. Therefore, my country's high-voltage transmission lines have the characteristics of wide coverage, many points, and long lines. After the transmission line is laid, it is necessary to check the status of the transmission line frequently in order to maintain the faulty transmission line in time. Among the factors that endanger transmission lines, there are more bird damage, ice coating, entanglement of garbage and other sundries, and scratches of tall construction vehicles, etc., which will cause failure or even damage to transmission lines.

Among the factors that endanger transmission lines, there are more bird damage, ice coating, entanglement of garbage and other sundries, and tall construction vehicles scratching, etc., which will cause failure or even damage to transmission lines

Usually, these hidden dangers can only be discovered in time through multiple inspections. In the past, manual patrols were used. However, due to the special location of some transmission lines, it is not easy to observe manually. Therefore, in recent years, machines have gradually replaced manual patrols. For example, through UAV patrols to collect environmental information of transmission lines. In the existing UAV inspection, there are two ways for UAV to transmit images. One is that the UAV collects in real time and establishes a connection with the ground station through a communication link. In order to realize image transmission; the other is that the UAV saves the collected video stream to the onboard SD card, and after the UAV returns, the video stream data is obtained by reading the SD card

[0003] For the first solution, the UAV generally interacts with the ground station through a self-built WIFI link, but the transmission of data in this way has a great limitation on the distance between the UAV and the ground station; The 4G / 5G communication module establishes a communication link with the ground station through the mobile network to transmit data. However, the mobile cellular network is prone to signal instability and disconnection during the flight of the drone, which affects data transmission.

On the other hand, real-time transmission is very power-hungry, and the power storage capacity of drones is very limited, which cannot support long-term image / video stream data transmission

For the second solution, the memory of the onboard SD card is limited, which cannot meet the needs of long inspections

[0004] On the other hand, the ground station performs image recognition after obtaining the image. If there is a foreign object, it can only judge that there is a foreign object in the cruise path, and further analysis of the location of the foreign object is required manually, and the cruise route is usually not short. Therefore, for foreign object analysis heavy workload
