When the battery capacity of device 200 to be charged reaches given threshold, device 200 to be charged passes through the second communication module
204 send charging control signal to charging unit 100, stop charging and issue the user with prompt, as warning light is always on, buzzer
Issue prompting sound etc..
In above-described embodiment, wireless charging, which refers to, carries out energy transmission by alternating electromagnetic field or radio wave, does not need
The attachment devices such as attaching plug, socket, conducting wire.Compared with wired charging, wireless charging do not have power cable frequently plug and
Bare exposed conductor exists, and eliminates the danger of frictional dissipation, electric shock, improves the convenience of electric energy transmission, significantly reduces charging
The quality and volume of system.Detection module is configured in wireless charging device, if the detection module detect charging unit with it is to be charged
When occurring obstruction among device, prompt can be issued and stop charging or the in short-term charging of drop power；If detection module detection charging
When not occurring obstruction among device and device to be charged, the information based on device to be charged feedback is charged, and (e.g., trickle fills
Electricity, constant-voltage charge, constant-current charge, quick charge etc.).
In above-described embodiment, in the design of cue module, cue module is by warning light, buzzer, supersonic generator
Equal components composition, above-mentioned warning light is for prompting user's charged state, and buzzer for prompting user in abnormal cases.It can also
It also is used as driving living body when living body occurs in detection, the supersonic generator is for driving some effects to wireless charging efficiency
And the living body sensitive to ultrasonic wave.
In the design of In vivo detection sensor, when being detected as living body by In vivo detection sensor, charging unit is closed
Detection module and the first communication module, bee while which is constantly flashed by the warning light of the cue module of charging unit
The device that rings issues prompt tone and prompts user, and certain effect of driving is generated to living body, and supersonic generator work issues living body
Sensitive signal is to drive living body.
