A remote controllable multi-terminal wireless charging system

Abstract

The invention belongs to the field of wireless charging technology, and discloses a remote controllable multi-end wireless charging system. The remote controllable multi-end wireless charging system comprises main transmitting equipment, one or a plurality of sets of sub receiving equipment. An MCU, an IO module, an RF communication module, a Bluetooth module, a power control circuit and a resonant transmitting circuit are integrated in the main transmitting equipment. An MCU, an IO module, an RF communication module, a resonant receiving and rectifying circuit and a power control circuit areintegrated in the sub receiving equipment. The main transmitting equipment transmits wireless electric energy to the sub receiving equipment and furthermore realizes operation state control on the subreceiving equipment through internal network communication. Communication connection between an upper computer and the main transmitting equipment is established through Bluetooth, thereby realizingexternal control. A remote end and the upper computer realizes remote control to the integral device through Internet, thereby settling a problem that a load cannot perform free movement in charging of existing wireless charging equipment. Combination of an inner communication mode and an external communication mode make the wireless charging system realize advantages of openness, expandability and flexibility. Furthermore application field and use range of the wireless charging system are expanded.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and more specifically relates to a remote controllable multi-terminal wireless charging system. Background technique [0002] Wireless charging technology (WPT, Wireless Power Transfer) is a technology that realizes energy transmission between power sources and electrical equipment in a non-contact wireless manner. It is widely used in fields such as electric vehicles, medical equipment, and small household appliances. In daily life, the most typical application of wireless charging technology is a one-to-one wireless charging system for mobile phones, which mainly includes a charging stand (wireless energy transmitter) and a charging adapter (wireless energy receiver). Its basic working principle is that the transmitter converts electric energy into an alternating electromagnetic field and transmits it outward through the coil, and the receiving coil rectifies the collected electromagn...
