Problems solved by technology

However, the traditional manual line inspection method requires a relatively large workload for the inspection personnel. In addition, the complex terrain of our country has added difficulties to the detection of transmission lines; Reliability creates a degree of error
In addition, traditional inspections require drones to be as close to power transmission and transformation equipment as possible to view details; however, due to the complex electromagnetic environment of on-site power transmission and transformation equipment, especially substations, drones will inevitably be affected by the electromagnetic field of our power equipment. Interference, specifically, the flight control of the UAV is interfered, causing the UAV to not work normally, ranging from damage to the aircraft, to damage to power facilities and causing casualties, which is extremely harmful, which in turn leads to the inability of the UAV to enter Carry out inspection work in the station

Embodiment

[0031] A. The quadrotor drone is used as the main body, and the drone bracket is used as the support to ensure that the drone 1 can land on the ground smoothly, and ensure that the drone has sufficient power when it takes off;

[0032] B. Preliminary analysis of the inspection line to be tested, to ensure that the UAV is within the range of endurance, and to ensure that the UAV and the ground receiving system are normal;

[0033] C. The UAV itself has a GPS positioning system and a gyroscope, which are sent to the ground image transmission station through the UAV image transmission station. Before starting the inspection, the staff fixed the field strength meter on the lower gimbal of the UAV to ensure that the RS232 video output interface of the field strength meter can be transmitted to the main body of the UAV. After ensuring that everything is normal, start the UAV.

[0034] D. When the UAV reaches the vicinity of the line to be inspected through GPS positioning, keep a ce...

Abstract

The invention discloses an obstacle avoidance system of a UAV field intensity meter based on power transmission and transformation equipment and a method of the system. The system comprises a multiple-rotor UAV, a UAV body is provided with a flight control system, a movable holder is mounted on a UAV support, and the field intensity meter is mounted on the holder; data of the field intensity meter is transmitted to the flight control system via a data reading interface of the UAV, the flight control system is connected with a picture and video processing system, and the picture and video processing system transmits the data to a ground reception system via a wireless transmission system; and the flight control system is controlled by a ground remote control system. According to the system and method, tour inspection can be carried out on power transmission lines as well as on a transformer station, the working area of the UAV can be broadened substantially, the probability of out-of-control accidents caused by that flight control of the UAV is interfered by an electric field, the safety of the UAV itself as well as power facilities is protected, and the tour inspection efficiency of the power transmission and transformation equipment can be improved substantially.

Description

technical field [0001] The invention relates to an obstacle avoidance system and a method thereof for an unmanned aerial vehicle-mounted field-strength instrument, in particular to an obstacle-avoidance system and a method for an unmanned aerial vehicle-mounted field-strength instrument based on power transmission and transformation equipment, and belongs to the technical field of power transmission and transformation equipment. Background technique [0002] my country's vast territory and complex terrain lead to a wide distribution of transmission lines in our country. Moreover, the natural environment is complex and changeable, and the power transmission line is exposed to the wild for a long time. On the one hand, it has to bear the pressure brought by the power load, and on the other hand, it has to be damaged by external forces such as lightning flashover, pollution and corrosion, and wind and rain for a long time. As a result, hidden dangers such as wear and tear of tr...
