Problems solved by technology

[0004] At present, the application of drone inspections for indoor substations is not widespread. The original GPS signal cannot penetrate the wall, resulting in the traditional miniature drones not receiving outdoor GPS signals when flying indoors, unable to realize their own positioning, and thus unable to complete the inspection. Inspection work

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] like figure 1 As shown, an indoor substation inspection UAV positioning method includes the following steps:

[0042] 1) Select an indoor substation, use the satellite navigation receiver to construct the real three-dimensional coordinate system of the indoor substation, and provide the map required for UAV flight.

[0043] Described step 1) specifically comprises the following steps:

[0044] 1-1) Select a certain indoor substation, place the satellite navigation receiver at a point on the ground outside the indoor substation, and the satellite navigation receiver receives the position signal calculated by the outdoor real satellite to obtain the position of the point on the ground outside the indoor substation;

[0045] 1-2) Coordinate conversion: In addition, due to the navigation message received by the satellite navigation receiver, the posi...

Abstract

The invention discloses an indoor transformer station inspection unmanned plane positioning method. The method comprises steps that a real three-dimensional coordinate system of an indoor transformerstation is constructed; an indoor positioning system based on the UWB technology is constructed; an indoor positioning system based on the pseudo-satellite technology is constructed; the indoor positioning system based on the UWB technology is utilized to measure the distance of an unmanned plane, the acquired distance measurement information is solved, and the present position information of theunmanned plane is acquired; and 5), according to the acquired position information, simulation satellite signals are generated and broadcasted, and self positioning is realized. The method is advantaged in that the UWB-based indoor positioning system is utilized to acquire the present position information of the unmanned plane in the indoor transformer station environment, the simulation satellitesignals are generated and broadcasted based on the pseudo-satellite indoor positioning system according to the present position information, self positioning is realized, a problem that GPS signals cannot be received in the unmanned plane indoor transformer station inspection process is solved, and indoor and outdoor seamless positioning of the unmanned plane is realized.

Description

technical field [0001] The invention relates to a positioning method for an indoor substation inspection drone. Background technique [0002] With the rapid development of urban construction, the number of substations continues to increase and the voltage transformation lines become more complex, which leads to a rapid increase in the workload of manual inspections and more intense safety issues. The traditional manual inspection mainly relies on the substation staff to actively inspect the equipment area of ​​the substation, observe and manually record the operating status of the equipment through sensory observation, so as to ensure the safe operation of the substation. However, the huge workload puts a heavy burden on the inspectors, which will cause some inspectors to be passive and slow down, and there are phenomena such as missed inspections and false inspections, which bring serious safety hazards; in addition, the environment of the substation is complex and there ar...
