Laser, microwave and mechanical wave etc.), electric energy is converted to by energy is relayed after sky transmits a distance, then through receiver, is realized
Wireless power transmission.
The wireless power technology to have come out now can generally be divided into three classes according to its electric energy transmission principle:
The first kind is electromagnetic induction principle used by contactless charging technique, and this contactless charging technique is being permitted
Using increasingly extensive in more portable terminals.In this seed type, two coils are placed on close position, when electric current is at one
When flowing in coil, generated magnetic flux becomes medium, causes also to generate electromotive force in another coil.Theoretical and experience is all
Show: when primary current frequency, amplitude are higher, former and deputy back gauge is smaller, compared with air, the opposite magnetic of magnetic core surrounding medium
When conductance is bigger, the efficiency of transmission of electric energy is higher.
Second class is the principle that directly applies electromagnetic wave energy and can be sent and received by antenna.Microwave power transmission, just
It is that directional transmissions are gone out after focusing microwave, in receiving end by RECTIFYING ANTENNA (rect2enna) the microwave energy received
It is converted into direct current energy.
Third class is the resonance method using electromagnetic field.Harmonic technology is widely used in electronic field, still, in power supply skill

And alternating current is provided to charge coil 1, in order to which charge coil 1 is by alternating current transmission to power receiving coil 2.
It is to be understood that inverter is that direct current energy (equipment such as supplying cell, battery electricity) is changed to strike a bargain
The equipment of galvanic electricity (generally 220V, 50Hz alternating current, naturally it is also possible to be the alternating current of other frequencies or voltage).It is by inversion
Bridge, control logic and filter circuit composition.Be widely used in air-conditioning, home theater, electric wheel, electric tool, sewing machine,
DVD, VCD, computer, TV, washing machine, smoke exhaust ventilator, refrigerator, video recorder, massager, fan, illumination etc..Inverter is a kind of
Mature existing equipment.Specifically, inverter is the transformer of DC to AC a kind of, it is in fact that a kind of voltage is inverse with converter
The process of change.Converter is the alternating voltage of power grid to be changed into stable 12V DC output, and inverter is by Adapter
The 12V DC voltage of output is changed into the High Level AC Voltage of high frequency；Two parts equally all use and use to obtain more pulsewidth
(PWM) technology of modulation.Its core is all a PWM integrated manipulator, and that Adapter is UC3842, and inverter is then adopted
With TL5001 chip.3.6~40V of operating voltage range of TL5001, inside set an error amplifier, an adjuster,
Oscillator, the PWM generator for having dead zone function, low-voltage variation circuit and short-circuit protection circuit etc..
It certainly, can also be right if voltage to frequency of default power supply 3 etc. is undesirable even if default power supply 3 is alternating current
Electric current is converted, and suitable alternating current is converted into.It is rectified into specifically, default power supply 3 can carry out conversion by converter
DC conversion is later suitable alternating current by inverter by the direct current of 12V.Specifically, converter is referred to computer
Power supply adaptor or the related devices such as phone charger.
It should be noted that converter is also a kind of existing device, and do not drawn in the present embodiment.But
By converter by AC conversion be direct current be a kind of conventional technical means.
Embodiment two
In practical application, some intelligent door locks not only need to connect the default power supply being arranged in outdoors, it is also necessary to which connection is set
It sets in main controller outdoors；Such as: the corridor doorway of a floor in cell unit building is arranged in the door lock in cell unit building, the door lock
Gate on.When I have a visit from a guest, needing resident by setting, controller sends control signal at home, controls door-lock opening.
Such as: parlor and the farther away house of door, when guest comes to visit, user may need the controller by the way that parlor is arranged in control
Door-lock opening, so that guest enters.In current scheme, it is attached between main controller and door lock by signal wire.Signal wire
It is also to pass through doorframe and door in such a way that door-hinge threads, signal wire is passed through from door-hinge, when door opening and closing, door-hinge and door and doorframe
Relative position can convert, may stretch or compression signal line, reduce the service life of signal wire, or even damage signal

Charge coil 1 connects inverter by the first modulator/demodulator 6；Charge coil 1 is for defeated to the first inverter 4
Alternating current out is modulated, so that the alternating current of the first inverter 4 output carries the first signal, and is mentioned to charge coil 1
For modulated alternating current；
Second modulator/demodulator 7 connects power receiving coil 2, and the first induced current for generating to power receiving coil 2 solves
It adjusts, obtains second signal；
Second modulator/demodulator 7, is also used to connect door lock 11, sends second signal to default door lock 11.
So set, can not only transmit electricity between charge coil 1 and power receiving coil 2, signal transmission can also be carried out.
The control signal that main controller 5 is sent is transferred to control of the intelligent door lock completion for intelligent door lock.
Modulator/demodulator is the abbreviation of Modulator (modulator) Yu Demodulator (demodulator), and Chinese is known as adjusting
System/demodulator (Hong Kong and Taiwan are referred to as modem) is referred to as " cat " according to the partials of Modem cheek by jowl.It is passed through in transmitting terminal
Modulation converts digital signals into analog signal, and converts analog signals into the one of digital signal again by demodulation in receiving end
Kind device.
Digital signal is exactly converted into the defeated analog signal of phone line by so-called modulation；Demodulation, i.e., analog signal
It is converted into digital signal.It is collectively referred to as modulator/demodulator.
The English of modulator/demodulator is MODEM, its effect is analog signal and digital signal " translator ".Electronics
Signal is divided to two kinds, and one is " analog signals ", and one is " digital signals ".The telephone line transmission that we use is simulation letter
Number, and what is transmitted between PC machine is digital signal.So when you want that the computer of oneself is connected into Internet by telephone wire,
Just it must carry out " translation " two different signals using modulator/demodulator.After being connected into Internet, when PC machine is sent out to Internet
Deliver letters breath when, what it is due to telephone line transmission is analog signal, so having to modulator/demodulator come digital signal " translation "
It at analog signal, can just be transmitted on Internet, this process is called " modulation ".When PC machine obtains information from Internet
When, since the information transmitted by telephone wire from Internet is all analog signal, so PC machine is wanted to understand them, it is necessary to
By modulator/demodulator this " translation ", this process is called " demodulation ".Generally speaking it is known as " modulating/demodulating ".
Main controller 5 sends control signal to the first modulator/demodulator 6 in the application (signal is generally digital signal herein)
Afterwards, the alternating current that the first modulator/demodulator 6 provides the first inverter 4 is modulated, so that the alternating current has been stayed in and has been converted into
The signal that the main controller 5 of analog signal is sent.By charge coil 1, (it is a kind of special to regard charge coil 1 as at this time later
Loop aerial) signal is issued.Power receiving coil 2 receives the signal that charge coil 1 is sent, and passes through the second modulator/demodulator 7
