technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging system for a drone with an optical communication function. Background technique [0002] In order to solve the insufficient endurance of drone inspections, the traditional wired charging method has exposed shortcomings such as poor flexibility, low reliability, and low autonomy. In response to these problems, the wireless charging of UAVs is becoming more and more widely used. The wireless charging of drones usually adopts inductive coupling power transfer ICPT (inductive coupling power transfer). During the wireless charging process of drones, it usually needs to communicate with the charging airport. [0003] The existing energy and signal synchronous transmission technology either constructs a pair of coupling coils separately for signal transmission, or intercepts a part of the energy coupling coil as a signal coupling coil for signal transmissi...

Problems solved by technology

Generally speaking, in the environment of the existing ICPT system, there is usually a certain intensity of electromagnetic interference. Although the interference limit can be reduced under the existing technology, due to the complex and changeable environment, and through the wireless in the electromagnetic induction mode The communication method determines the characteristics of low-energy and short-distance communication of its signal transmission, and its attenuation is very severe in the process of air transmission. The influence of electromagnetic interference on it must be considered, which increases the complexity of system design.

In addition, it is necessary to adopt the method of simultaneous transmission of electromagnetic induction mode signals and magnetic coupling induction energy. For the separate transmission of power and signals, the transmission equipment designed by many researchers is cumbersome and complicated, and the power and signals affect each other, resulting in system performance degradation.

However, the transmission of power and signals in the same channel also has problems such as the power transmission power drops and the signal transmission is seriously affected.
