Embodiment 1

[0047] The targets of the inspection include Yuchang towns and rural areas, and the length of the entire power supply network is 4km. There is no electrified railway nearby, and there is no high-grade power supply line crossing. During the inspection, the personnel set the inspection target located in the town as manual, and the rest of the objects are assigned to the drone. Calculate the hovering angle according to the tower height and tower properties (tension resistance, branch line, branch) of the target object. For example, when the information is a 10-meter tension rod and there is no branch inspection, calculate the angle of the pole's entry and exit line (based on latitude and longitude), Then, according to the focal length of the camera on both sides of the incoming and outgoing lines, take clear photos of the insulating string porcelain bottles at both ends as close as possible.

Embodiment 2

[0049] The inspection target is located in a mountainous country, and if it is crossed by other power lines, it can be all assigned to the UAV, and the UAV first calculates the route with the least leap over the area based on the cross-crossing information of the inspection object. When approaching the crossing area, the flight altitude is automatically calculated, and the flight speed is reduced at the same time, reminding manual video surveillance, slowly flying over the crossing area, and then patrolling normally to ensure the safety of inspections.

Abstract

The invention discloses an operation method for man-machine collaborative inspection of a power distribution network, relates to the field of inspection of power distribution network equipment, and solves the problems of high time consumption and low efficiency of manual inspection. The method comprises the steps that an unmanned aerial vehicle monitors surrounding environment pictures of an inspection object on an inspection route and sends the pictures to an inspection management platform to judge whether flight of the unmanned aerial vehicle is affected or not, the inspection management platform automatically analyzes and plans an affected area and sends the affected area to a mobile terminal and the unmanned aerial vehicle, and workers hold the mobile terminal to reach the inspection area, inspects the influence area to enter the influence area with the inspection object manually, sets a new area inspection task to the unmanned aerial vehicle, the inspection management platform shares, and the unmanned aerial vehicle performs inspection according to the new area inspection task, executes the step C and then executes the step E. The method is high in practicability, can be applied in a man-machine seamless combination mode, and greatly facilitates the inspection operation of the power distribution network.

Description

technical field [0001] The invention relates to the field of patrol inspection of distribution network equipment, in particular to an operation method for man-machine cooperative patrol inspection of distribution network. Background technique [0002] In the inspection operation of distribution network equipment, it is necessary to ensure that the personnel are in place, record the inspection information on site, and judge whether the equipment has potential safety hazards. It is currently the most widely used method to ensure that inspections are in place and complete records of inspection information are made through paper or electronic equipment. Manual patrol inspection mainly has the following disadvantages: First, it needs to manually go to the vicinity of the equipment one by one, which takes a lot of time and is very inefficient. Second, the information collected by manual inspection is incomplete and inaccurate. For example, the pictures taken by the equipment at t...
