Description

An autonomous inspection device for UAVs based on dual-light intelligent payloads

technical field

The invention relates to the technical field of intelligent hardware technology, in particular to an autonomous inspection device for drones based on dual-light intelligent loads.

Background technique

With the market demand of the green energy industry and the promotion of the government, the photovoltaic industry has developed rapidly. Photovoltaic power stations are often built in remote areas with few people and a large construction area, which also brings difficulties to inspections. In recent years, the use of control The way drones inspect photovoltaic facilities has been improved, but there are still difficulties in manned operation and manned analysis.

The passive method of infrared can detect the failure points of solar panels and equipment very well. However, the disadvantage of infrared video is that it has low resolution and no chromaticity information. Intelligence relies on thermal difference distribution, so there will not be too much detailed information about objects .

UAV operation generally requires professionally trained personnel to operate. In addition, the data after infrared detection also requires personnel with certain experience to determine the specific cause of the fault and come up with a solution to the fault.

During the inspection process, large-area solar panels can be positioned to find out the specific location of damaged solar panels. Traditional drones use GPS positioning, and the positioning accuracy is not enough to locate solar panels, which creates additional difficulties for positioning and troubleshooting.

Another reason why drones cannot be completely unmanned during the inspection process is that the flight time of the drone after a single charge or refueling is short, and the charging or refueling process cannot be unmanned, and human participation is required .

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide an autonomous inspection device for drones based on dual-light intelligent loads, including a drone platform, and the device also includes:

The imaging load of the visible light and infrared dual-light band pan/tilt and stable platform arranged on the lower part of the UAV platform;

A data transmission module arranged in the middle part of the unmanned aerial vehicle platform;

An intelligent terminal module arranged on the upper part of the drone.

Preferably, the device further includes a magnetic resonance-based wireless charging module.

Preferably, the wireless charging module specifically includes a battery and a battery wireless charging receiver.

Preferably, the imaging load of the sightseeing belt pan/tilt and the stable platform specifically includes an infrared thermal imaging camera, a visible light camera, a three-axis pan/tilt, and a stabilizer.

Preferably, the data transmission module specifically includes a data transmission circuit board and a data transmission antenna.

Preferably, the device automatically returns to the voyage through the smart terminal and autonomously wirelessly charges through the wireless charging module.

Preferably, the intelligent terminal conducts precise navigation through the fusion of electronic maps, GPS and visual navigation, and identifies the position and number of the solar panels.

Preferably, the intelligent terminal directly analyzes and obtains the specific information of the damaged solar panel.

Compared with the prior art, a UAV autonomous inspection device based on dual-light intelligent load provided by the present invention has the following advantages: it proposes fusion recognition and visual navigation of infrared and visible light, and at the same time adopts artificial intelligence to realize troubleshooting, Fault analysis, fault handling decision.

In addition, another problem in the large-scale inspection of drones is the limitation of the flight time of the drone. When the battery of the drone is low, it needs to return to the voyage to replace the battery or refuel manually, which is very inconvenient. Using the wireless charging method, the UAV can return to the voyage autonomously and charge itself.
