According to delivery of electrical energy principle, wireless power transmission can be divided three classes haply: the first kind is the direct coupling type of transformer principle, although this mode power is larger, is only suitable for closely; Equations of The Second Kind electric wave wireless energy transmission technology, directly utilize the electromagnetic wave energy can be by the principle of antenna transmission and reception, although this mode has realized the transmission of long distance and high-power energy, but Energy Transfer is limited by direction, can not cut-through thing, and loss is larger, human body and other biology are had to grievous injury; The 3rd class is non-radiation coupling resonance manner, and this technology can be transmitted in the situation that having barrier, and transmission range is also distant, and through-put power is also larger, and to not injury of human body.
In sum, the third delivery of electrical energy mode has very large potentiality to be exploited, and its appearance has further expanded application target and the field of wireless power transmission technology.Certainly, this biography can pattern will become new developing direction of wireless power transmission.The research of magnet coupled resonant type electric energy transmission technology at present, still in the starting stage, mainly concentrates on raising and the application of special occasions research of systematic function.
In order to make radio energy transmission system be operated in optimum state, conventionally require transmitting coil strictly to align with receiving coil, reduce system capacity loss, make system efficiency of transmission maximum.Yet in practical work process, system inevitably can be interfered, and such as there are horizontal-shift or coupling angle etc. between sending and receiving coil, the absorption of these disturbing factors causes the decline of system efficiency of transmission, cause System Reactive Power increased power, cause energy loss.
The present invention is intended to solve radio energy transmission system and is being subject in external interference situation, the problem that system efficiency of transmission declines.Designed that a kind of intellectuality, real-time are high, the strong operating frequency tracking means of reliability.
Summary of the invention
Technical problem to be solved by this invention is, proposed a kind of frequency-tracking device of the WPT of being applied to system, and this device has intellectuality, real-time is high, reliability is strong feature.
The technical solution adopted in the present invention is: the frequency-tracking device that is applied to WPT system, comprise DSP control system, it is the key control unit of apparatus of the present invention, it is characterized in that, also be provided with: power detecting system is for detection of the electrical energy parameter of WPT system, wireless transmitter module is for transmitting the delivery of electrical energy being obtained by power detecting system, and wireless receiving system is for the wireless signal that receives wireless transmitting system and send and be transported to DSP control system.
Described DSP control system is one of core of WPT system works frequency self-adaption adjusting device, comprises input circuit, DSP minimum system and output circuit etc.The parameter that the electrical energy parameter obtaining from wireless receiving system and DSP set compares, if be greater than setup parameter, dsp system sends control signal and changes WPT system works frequency, if be less than setup parameter, dsp system can not send the control signal that changes operating frequency.
Described power detecting system can detect the electrical energy parameter of WPT system in real time, and electric power signal is transferred to wireless transmitting system transmitting after treatment.
Described wireless receiving system system can receive the signal of telecommunication of wireless transmitting system transmitting in real time, and by this signal of telecommunication, gives dsp system and compare analysis.
A kind of frequency-tracking device that is applied to WPT system of the present invention, this device has high robust, high reliability, intelligentized feature.After system energising work, power detecting system detects the electric power signal of WPT system in real time, signal by wireless transceiver system transmits, signal is delivered to dsp system and is compared analysis the most at last, during output control signal, WPT system works is at optimum frequency point, make WPT system efficiency of transmission maximum, avoided the loss of WPT system energy when being subject to external interference.
