[0004] In the existing manual inspection methods, there are many "blind areas", which consume a lot of manpower and material resources, and cannot meet the economic and security requirements of smart grid development; manual inspections of overhead transmission lines, in the complex environment of the field Under the circumstances, the personal safety of the staff is easily threatened by other factors in nature. However, when the existing UAV patrols the line, due to its inaccurate positioning, it cannot meet the technical requirements for the line inspection; because at a suitable distance, the line inspection UAVs can achieve the best line inspection results, thus supporting our correct judgment on the operation of the line

At present, when the UAV is patroll...

Abstract

An electromagnetic field positioning method of an overhead transmission line patrol unmanned aerial vehicle and an apparatus thereof are disclosed. Through measuring a magnetic field vector and an electric field vector of a position where an unmanned aerial vehicle is located, according to a mathematic relation of an electromagnetic field vector and a distance, a space position between the unmanned aerial vehicle and a power transmission line is determined; and through wireless transmission equipment, acquired space position data between the unmanned aerial vehicle and the power transmission line is transmitted to a terminal control system. A three-component method is used to measure the magnetic field vector and a three-axis orthogonal method is used to measure the electric field vector. By using the method and the apparatus of the invention, positioning accuracy of the line patrol unmanned aerial vehicle can be effectively increased; uncertainty brought by observation by naked eyes is avoided; effects of safety and high efficiency are achieved; and simultaneously an intelligent degree of line patrol is increased.

[0057] Examples:

[0058] according to figure 2 As shown in the production of magnetic field vector measuring device 2, according to image 3 The electric field vector measuring device 3 is produced as shown; the magnetic field vector measuring device 2 and the electric field vector measuring device 3 are installed at the bracket 1.2 of the UAV 1; the magnetic field vector measuring device 2 and the electric field vector measuring device 3 are connected to the wireless through a transmission line The transmitting device 4.1 of the transmission device 4, and the transmitting device 4.1 of the wireless transmission device 4 are installed in the fuselage 1.1 of the drone 1; the receiving device 4.2, the alarm device 5, and the terminal control system 6 of the wireless transmission device 4 are installed in Ground control room.

[0059] Start UAV 1 to fly to the vicinity of transmission line 7, measure the magnetic field vector 8 and electric field vector 9 at the position of UAV 1 at this time, and calculate the distance between it and the transmission line 7 at 0.5m to 2m. Between; continue to control UAV 1 to fly along transmission line 7. When UAV 1 runs to point A, it detects that the distance between UAV 1 and transmission line 7 is greater than 2m, and the alarm device 5 sends out the distance is too large Warning, prompt the operator to adjust to the direction of decreasing distance; continue to control UAV 1 to fly along the transmission line 7. When UAV 1 runs to point B, the distance between UAV 1 and transmission line 7 is detected If the distance is less than 0.5m, the alarm device 5 will issue a warning that the distance is too small, prompting the operator to adjust in the direction of increasing distance.

[0060] The invention can effectively improve the positioning accuracy of the line patrol UAV, avoid the uncertainty caused by naked eye observation, achieve the effect of safety and high efficiency, and at the same time improve the degree of intelligence of the line patrol.
