The workflow of the circuit being related in accompanying drawing 2 is as follows：Electric capacity C1 obtains electric energy from built-in power generation device, and stores.
When in electric capacity C1 without storage electric energy, voltage is 0V between two electrodes of C1；When built-in power generation device starts to export electric energy,
Electric capacity C1 starts to obtain and stores, and voltage starts positive growth between two electrode, and with the accumulation of electric capacity internal electric energy,
Voltage also gradually rises between two electrodes.The circuit of NMOS tube M1, PMOS M2 and resistance R4 compositions constitutes switches set, opens
" conducting " of pass group and " cut-off " state are controlled by the grid voltage of NMOS tube M1, when the grid voltage of NMOS tube M1（It is designated as
Vg1）The cut-in voltage intrinsic more than NMOS tube M1（It is designated as Vg1 (th)）When, NMOS tube M1 is in " conducting " state.Due to NMOS
Pipe M1 " conducting ", the grid of PMOS M2 pulled down to ground level so that PMOS M2 is also at " conducting " state, so that
VIN networks are in connection status, the intelligence that the built-in power generation device that VIN ends are connected can be connected by VOUT ends with VOUT networks
Lock function circuit is powered, and now switches set is generally in " conducting " state；When the grid voltage Vg1 of NMOS tube M1 is less than NMOS tube
During intrinsic cut-in voltage Vg1 (th) of M1, NMOS tube M1 " cut-off ", due to NMOS tube M1 " cut-off ", the grid of PMOS M2 leads to
Cross resistance R4 and be essentially pulled up to the current potential same with the source electrode of PMOS M2 so that PMOS M2 is also at " cut-off " state, at this moment
Connection between VIN networks and VOUT networks is cut off, and the built-in power generation device that VIN ends are connected cannot be connected by VOUT ends
Smart lock functional circuit power, now switches set is generally in " cut-off " state.
As can be seen here, the control circuit can automatic decision when completion has been collected and stored to electric energy, and when completing,
Powered from trend smart lock functional circuit.In power supply process, the normal work for smart lock functional circuit is fallen in supply voltage
Before outside voltage range, power supply is automatically cut off.
Resistance R1 in accompanying drawing 2, R2, R3 are three resistance of offer voltage divide function.Diode D1 is mainly used for control electricity
The one-way flow of stream.This four electronic devices, determine the opportunity of switches set " conducting " and " cut-off ".It is described in detail below：
When there is no electric energy in electric capacity C1, electric capacity C1 voltage Vc=0V over the ground, the grid voltage Vg1 of NMOS tube M1 is by the electricity
Pressure Vc is obtained through resistance R1 and R2 partial pressure, now grid voltage Vg1=0V, and grid voltage Vg1<NMOS tube M1 is intrinsic
Cut-in voltage Vg1 (th), switches set is in " cut-off " state.Electric capacity C1 is in the stage for gathering and storing electric energy, with built-in
TRT exports electric energy, and electric capacity C1 storage electric energy, voltage Vc is raised, and the grid voltage Vg1 is also raised in proportion therewith；When
When the grid voltage Vg1 is increased to cut-in voltage Vg1 (th), switches set goes to " conducting " state, electric capacity by " cut-off "
C1 starts to be powered to smart lock functional circuit, and the value of voltage Vc described in this moment is designated as Vc (th1).When switch module just " is led
It is logical " when, the voltage at VOUT ends（It is approximately equal to the voltage Vc）By after the positive feedback path being made up of resistance R3 and diode D1,
The grid voltage Vg1 is drawn high into the voltage much larger than the cut-in voltage Vg1 (th) immediately, it is ensured that electric capacity C1 is sustainable
For smart lock functional circuit is powered.
The unilateral conduction of diode D1, it can be ensured that the voltage Vc of electric capacity C1 before the Vc (th1) is increased to, electric capacity
C1 will not be powered by this path being made up of resistance R1, R3 and diode D1 to smart lock functional circuit；Meanwhile, by
There is the positive feedback path being made up of resistance R3 and diode D1 in circuit so that when the voltage Vc of electric capacity C1 just starts to reduce
When, the grid voltage Vg1 also will not be with the cut-in voltage Vg1 (th) be dropped below at once, and switch module will not stand
Carve " cut-out ", and then be able to ensure that electric capacity C1 is continuously smart lock functional circuit and powers.
If hereafter built-in power generation device does not continue to output electric energy, or the generated output of built-in power generation device is less than intelligence
The power of lock function circuit, then the electric energy in electric capacity C1 can gradually decrease, the voltage Vc at its two ends also can be reduced gradually, with this
The reduction of voltage Vc, the grid voltage Vg1 is also reduced by a certain percentage therewith, finally, when grid voltage Vg1 be reduced to it is small
When cut-in voltage Vg1 (th), switch module " cut-off ", electric capacity C1 stops power supply, this at moment its two ends voltage Vc
Value is designated as Vc (th2).
Simply enumerate above, energy-storage travelling wave tube A is not limited to single electric capacity, can be made up of one or more electric capacity, it is also possible to
By it is well known to those skilled in the art other have deposit can the element of function constitute；Three potential-divider networks B, C, E, each be by
The module with voltage divide function that one or more electronic components are constituted, electronic component herein includes but is not limited to electricity
Resistance, electric capacity, diode etc.；Unidirectionally controlled F is not limited only to diode, can be made up of one or more electronic components
Module with unilateal conduction characteristic；Controlling switch group D is also not limited only to the circuit shown in accompanying drawing 2, can be by one
Or multiple electronic components are constituting, module controllable, with " switch " function, electronic component herein including but not
It is limited to resistance, electric capacity, inductance, diode, metal-oxide-semiconductor, transistor, electron tube, photoelectrical coupler, electromagnetic relay etc..
Referring to accompanying drawing 3, with the waveform of each voltage in the above-mentioned control circuit of the actual measurement of oscillograph.Wherein CH1 passages（It is attached
Icon is designated as 1）Represent the waveform of electric capacity C1 both end voltages, CH2 passages（Reference is 2）Represent and provide output voltage to load
The waveform of the voltage at VOUT ends, CH3 passages（Reference is 3）Represent the waveform of the grid voltage of transistor M1.
As can be seen that from the A moment to the B moment, controlling switch group is in " cut-off " state from the oscillogram of accompanying drawing 3,
Electric capacity C1 is in the storage electric energy stage, and the voltage Vc at its two ends is stepped up, and the grid voltage Vg1 of NMOS tube M1 also rises therewith
Height, VOUT network voltages are always 0V.At the B moment, the grid voltage Vg1 is increased to the intrinsic cut-in voltages of NMOS tube M1
Vg1 (th), controlling switch group " conducting ", VOUT terminal voltages are increased to and are approximately equal to voltage Vc；Meanwhile, VOUT terminal voltages are by by electricity
The grid voltage Vg1 moments are drawn high voltage relatively higher by the positive feedback path that resistance R3 and diode D1 is constituted, so that really
Guarantor electric capacity C1 is continuously smart lock functional circuit and powers.
The B moment, electric capacity C1 storage electric energy was reduced between the C moment, the voltage Vc reductions at its two ends, the grid voltage
Vg1 is also decreased；At the C moment, the grid voltage Vg1 is reduced to the cut-in voltage Vg1 (th), and controlling switch group " is cut
Only ", now the grid voltage Vg1 is obtained by resistance R1 and R2 partial pressure again（During controlling switch group " conducting " by resistance R1,
R2 and R3 partial pressures are obtained）, therefore having the process that a moment falls, hereafter the voltage at VOUT ends be gradually decrease to 0V.
