RTK positioning-based unmanned aerial vehicle autonomous inspection system and method

Abstract

The invention discloses an RTK positioning-based unmanned aerial vehicle autonomous inspection system and a method thereof. The system comprises a ground terminal system and an unmanned aerial vehiclesystem. The unmanned aerial vehicle system comprises a multi-rotor unmanned aerial vehicle, a flight control subsystem, an airborne wireless communication module and a task load subsystem which is mounted on the multi-rotor unmanned aerial vehicle. The ground terminal system comprises a remote controller and a ground station. The flight control subsystem comprises a flight control module and an RTK positioning module. The flight control module is respectively connected with the airborne wireless communication module, the multi-rotor unmanned aerial vehicle, the RTK positioning module and thetask load subsystem. The task load subsystem comprises a cradle head and a camera arranged on the cradle head. The cradle head is used for controlling the shooting angle of the camera according to aninstruction from the flight control module. The camera is connected with the airborne wireless communication module, and the airborne wireless communication module is respectively connected with the remote controller and the ground station. According to the invention, the consistency of the photographing positions of each tower rod can be ensured. The number of potential safety hazards is reduced,and the convenience is provided for later data analysis.

Description

technical field [0001] The invention relates to unmanned aerial vehicle inspection, in particular to an autonomous inspection system and method for an unmanned aerial vehicle based on RTK positioning. Background technique [0002] With the construction of the power grid and the development of drone technology, the use of drones for power inspections has become a hot spot. There are two main inspection methods: one is controlled by drone pilots Fly around the tower to take pictures, but this method is extremely dependent on the pilot's technology, and even requires an additional gimbal hand to assist in taking pictures. If you want to conduct regular inspections on the same tower, it will undoubtedly increase safety hazards, and it is very difficult for the pilot to control the flight.

[0002] With the construction of the power grid and the development of drone technology, the use of drones for power inspections has become a hot spot. There are two main inspection methods: one is controlled by drone pilots Fly around the tower to take pictures, but this method is extremely dependent on the pilot's technology, and even requires an additional gimbal hand to assist in taking pictures. If you want to conduct regular inspections on the same tower, it will undoubtedly increase safety hazards, and it is very difficult for the pilot to control the flight. It is difficult to ensure the consistency of each tower photo location, which increases the workload of later data analysis; the second is to generate waypoint paths based on the GPS information of the tower and detailed parameters such as tower type, voltage level, tower height, insulator material, etc., so that Guide drones to conduct autonomous inspections

This method requires the cooperation of relevant departments to provide accurate data, which is relatively cumbersome and has certain restrictions. Moreover, if there is a deviation in the provided data, the aircraft may crash into the tower, which is extremely risky.
