-A kind of mobile drone autonomous charging base station and system technology field

[0001] The present invention relates to the technical field of drones, in particular to a mobile drone autonomous charging base station and system.

Background technique

[0002] UAVs have the characteristics of being small, light, low-noise, energy-saving, highly maneuverable, and intelligent. UAVs are used as aerial platforms to conduct cruise monitoring of terrain, landforms, engineering structures, etc., that is, "UAV + industry application", which has developed into its real rigid demand. UAVs can be widely used in the fields of land remediation monitoring, water conservancy project construction, natural disaster monitoring and evaluation, urban planning and municipal management, digital earth and other fields. At present, most UAVs use lithium polymer batteries as the main power source, Its battery life is about 30 minutes. During the cruise, the UAV's own electric energy reserves are relatively limited. After the electric energy is exhausted, it needs to stop flying and charge after landing. For long-distance, long-term cruise applications, such as regular dam inspections, disaster area surveys, etc., the infrastructure in the cruise area is incomplete or has been damaged, and it is unable to provide a charging platform and electrical energy for the cruised UAV. Therefore, the insufficient continuous cruise capability is one of the restrictive factors that limit the promotion and application of UAVs, and it is a huge shortcoming of its application in the civilian industry. The existing UAV charging technology has the following shortcomings: 1. Positioning devices, at this stage, mostly use laser alignment technology, electromagnetic interaction correction technology, etc., to correct the GPS positioning error, and realize the high-precision autonomous landing of the UAV. However, such devices are usually complex in structure and high in cost, and it is difficult to strike a balance between high precision and cost. At the same time, for cruising areas such as dams and disaster-stricken areas, the natural environmental conditions in the area are bad, often disturbed by strong winds, rainfall and other environmental factors, and there are big problems with positioning stability and reliability. The present invention includes an auxiliary landing device, which can realize It assists precision landing and fixes the role of drones, and the cost is low. 2. Open base station: Most of the drone charging base stations at this stage are open, which cannot effectively protect the drone. In the present invention, the base station is always in a closed state during the drone charging process. The man-machine is separated from the external environment, eliminating the influence of rain, snow, strong wind and other harsh weather on the drone; 3. The base station cannot be moved: at this stage UAV charging base stations are often fixed and cannot be moved. In engineering applications such as dam inspections, the cruising area is wide and the distance is long, and charging base stations need to be arranged along the line, which is extremely costly. The charging base station of the present invention is mobile and can be deployed in key monitoring areas, which greatly increases the number of unmanned Adaptability of base station; 4. Base station energy storage method: At this stage, most of the energy storage methods of drone charging base stations are solar energy. The charging base station of the present invention adopts multiple energy storage methods, adopts wind-solar complementary power generation technology, and combines wave energy. It can use one or more methods among solar energy, wind energy and wave energy to charge the base station under various climatic conditions.
