For achieving the above object, the invention provides a kind of wireless power supply, comprise range sensor, central control unit, transmitting coil, described range sensor is connected with described central control unit, and described central control unit is connected with described transmitting coil.
Preferably, described wireless power supply, also comprises parameter setting unit, for transmission range reference value.
The present invention also provides wireless power supply system, comprise power receiving system and above-mentioned wireless power supply, described range sensor is for measuring the measuring distance value between described power receiving system and described wireless power supply, when measuring distance value is less than or equal to the distance reference value preset, described central control unit drives described transmitting coil to open power supply process.
Preferably, described in the distance reference value that presets be the value of artificial input in advance, or for sampling the value obtained in setting-up time.
Preferably, described wireless charging system, also comprises display unit, for show preset distance reference value, measuring distance value, power receiving system electricity in one or more information.
The present invention also provides the wireless charging method of above-mentioned wireless charging system, starts or close power supply process according to the distance value between power receiving system and wireless power supply.
Preferably, described wireless charging method, comprises the steps:
First step, range sensor periodic scan measures the measuring distance value between power receiving system and wireless power supply, and this measuring distance value is transferred to central control unit;
Second step, the measuring distance value received and the distance reference value preset contrast by central control unit, and when measuring distance value is less than or equal to the distance reference value preset, central control unit drives described transmitting coil to open power supply process.
Preferably, described in the distance reference value that presets be the value of artificial input in advance, or for sampling the value obtained in setting-up time.
Advantage of the present invention and beneficial effect are: provide a kind of wireless power supply, wireless charging system and wireless charging method, can improve utilization rate of electrical, reduce waste of energy.
The present invention by arranging range sensor in wireless power supply, for measuring the measuring distance value between power receiving system and wireless power supply, and then determine to open or close power supply process according to the measuring distance value of power receiving system and wireless power supply, avoid and to open the electric energy low-conversion and poor efficiency that power supply process causes when the distance of power receiving system and wireless power supply is excessive, thus raising utilization rate of electrical, reduce waste of energy.
