The embodiment of the invention discloses an online charging supplying device and method for a patrol unmanned aerial vehicle. The online charging supplying device comprises a control base station anda grouping control circuit, wherein the control base station is connected with an energy storage charging circuit through the grouping control circuit, and a push-pull inverter circuit, a full-bridgeuncontrollable rectifier circuit and a BUCK circuit are arranged in the energy storage charging circuit; and the output end of the push-pull inverter circuit is coupled with a first resonance coil through a transmitting coil, the first resonance coil is connected with a second resonance coil through magnetic coupling, and the second resonance coil is connected with the full-bridge uncontrollablerectifying circuit through a magnetic coupling receiving coil. According to the system, a dynamic tuning branch is adopted for compensating the change of the original-stage inherent resonant frequencyof the system, the resonance of the primary emission coil of the system is realized while the working frequency of the system is ensured to be constant, and therefore the power transmission capability of the whole coupling mechanism is improved; and the unmanned aerial vehicle can flexibly supply electric energy through the electromagnetic induction technology, so that the cruising ability of theunmanned aerial vehicle is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of unmanned aerial vehicle charging, and specifically relates to an online charging and replenishing device and method for patrolling unmanned aerial vehicles. Background technique [0002] From the energy point of view, there are two main ways to increase the cruising range of UAVs: carrying more power or replenishing power multiple times during missions. For the former, since the relatively mature battery technology has developed to the bottleneck period, a larger battery capacity means a larger battery volume and weight, so increasing the battery capacity will definitely affect the maneuverability and lightweight of the drone; For the method of power supply through multiple times, if it is based on the charging technology of the traditional contact power conduction method, it means that the UAV needs to return to the base station or home port when it needs to replenish power, and...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides an online charging and replenishing device and method for patrol drones, which uses a dynamic tuning branch of phase-controlled inductors to compensate for the inherent resonance of the primary stage of the system caused by changes in mutual inductance parameters and loads in the constant frequency operating mode The change of frequency makes the natural resonant frequency of the primary stage consistent with the operating frequency of the system, thereby improving the power transmission capacity of the entire coupling mechanism and reducing loss, so as to solve the problem that it is impossible to maintain complete coupling due to its own performance or environmental factors in the prior art. Static, will eventually lead to changes in the relative position of the coupling mechanism, resulting in low power transmission capacity of the coupling mechanism
