Charging system for unmanned aircraft

Abstract

The invention discloses a charging system for an unmanned aircraft. The charging system is characterized by comprising a power-taking device, an electric energy transmitting device, an electric energy receiving device and an aircraft-mounted battery, wherein an overhead transmission line is arranged on the power-taking device; the electric energy transmitting device is for converting power frequency alternating current into high-frequency alternating current; the electric energy receiving device is arranged on the unmanned aircraft; electric energy transmission is realized in a wireless manner between the electric energy receiving device and the electric energy transmitting device; the aircraft-mounted battery is arranged on the unmanned aircraft, is used for supplying power to the unmanned aircraft, and is connected in series to a current loop of the electric energy receiving device. Compared with the prior art, an electric unmanned aircraft charging system based on an alternating-current power transmission overhead line provided by the invention has the advantages that a full-autonomous and safe charging way is realized for the unmanned aircraft, and the distance per charge of the unmanned aircraft is prolonged. Meanwhile, a high-frequency inductive constant-current charging circuit based on an unstable alternating-current power supply is provided, so that unmanned charging operation is fully realized, the dependence of the unmanned aircraft on a ground base or a mobile base station is reduced, labor operation is reduced, and labor cost is reduced.

Description

technical field [0001] The invention relates to a charging system, in particular to a charging system for unmanned aircraft. Background technique [0002] With the development of the times, society's demand for aerial missions is becoming stronger and stronger. Compared with manned aircraft, drones have many incomparable advantages: relatively small size, flexible overall layout, low cost, easy to use, can enter dangerous environments, and can meet the needs of special purposes. [0003] An electric drone is an aircraft powered by an electric motor rather than an internal combustion engine, and sources of power include fuel cells, solar cells, supercapacitors, wireless energy transfer, or other types of batteries. Electric aircraft uses electric propulsion system instead of internal combustion engine power, which has gained many advantages and unique qualities. The most prominent advantages are energy saving and environmental protection, high efficiency and low energy consu...

AI Technical Summary

Problems solved by technology

[0004] Existing electric drones usually return to the ground base when they need to be charged, and then remove the battery to charge or replace the battery. The disadvantages of this method are: first, the flying radius of the unmanned aircraft is small

Since battery life is limited by battery capacity and performance, unmanned aircraft cannot fly in the air for a long time. When the battery is exhausted, it needs to return to the ground base; secondly, it requires a lot of manual work

Although increasing the distribution density of ground bases or ground mobile base stations can increase the working radius of unmanned aircraft, the establishment of multiple bases or mobile base stations requires more manpower and material resources, which greatly increases economic costs.
