The DC signal of the rectification module output is obtained relatively after the filtering process of the filtration module
Smooth electric signal, in order to which the first energy storage module positioned at rear class carries out collection of energy to it.
In an embodiment of the present invention, first energy storage module includes at least one storage capacitor C3, wherein, institute
It is the low electric capacity of high pressure resistant vast capacity leakage current low power consumption, specifically, the tolerance of the storage capacitor C3 to state storage capacitor C3
Voltage >=500V, is preferably >=1000V；The μ F of capacitance >=500, are preferably >=1000 μ F, such as can select model
1000V/680 μ F electric capacity；Leakage current is less than 10 μ A (output current of most of friction generator is tens μ A)；Power consumption is less than
10 μ W (instantaneous power of most of friction generator is tens μ W).Wherein, the selection of storage capacitor C3 vast capacities is in order at
The consideration of its driving force, a core difficult point of friction generator collection of energy is exactly the collection of energy effect of energy collection module
Rate is relatively low, so may result in and the use that electric energy is still not enough to drive low-power consumption or even super low-power consumption is can be obtained in the unit interval
Electric equipment, and the control module at rear and energy management module are required to certain electric energy and could driven, accordingly, it is capable to measure receipts
Collection module has to carry out primary energy storage with the electric capacity of Large Copacity, can run up to enough electric energy, then just may be used
To drive follow-up electricity consumption module, that is to say, that the capacity of only storage capacitor is sufficiently large, just can guarantee that enough storing up electricity energy
Power, and then guarantee to effectively drive subsequent module work；The high voltage bearing selections of storage capacitor C3 are in order at for friction hair
The consideration of motor High voltage output；In view of the efficiency of energy collection of energy management circuit, storage capacitor C3 also needs to have electric leakage
The characteristics of stream is small and is lost small.
Certainly, first energy storage module can also use other energy storage devices, and the present invention does not make specific to it
Limit, as long as it effectively can collect and store the energy of input electrical signal.
In an embodiment of the present invention, the control module includes signal control module and switch module, wherein：
The signal control module is used for according to the voltage levels state of first energy storage module to the switch
Module exports corresponding control signal；
The switch module is used to control first energy storage module for rear according to received control signal
The power supply break-make of continuous module.
In an embodiment of the present invention, the signal control module is described to open using double hysteresis comparator chip IC L7665
Close module and use switch chip CD4051, both chips belong to chip commonly used in the art, join for its specific structure
Number, the present invention is repeated no more.Certainly, the signal control module and switch module can also use other control devices and derailing switch
Part, the present invention is not especially limited to it, as long as it can accurately control the first energy storage module for the confession of post-module
Electric break-make.
The control module is to control storage capacitor C3 electric discharges or stop the key component that electric discharge continues electric power storage, such as
Fruit without control module, on storage capacitor C3 cannot external any load, as long as because being connected to load, being supported on the unit interval
In the electric energy that consumes all will be greater than the electric energy that the first energy storage module is collected into the unit interval, specifically, because big portion
The instantaneous output highest of point friction generator only has tens μ W, if load is directly connected into the two of storage capacitor C3
End, because the consumption power of load will reach mW ranks, can thus make it that storage capacitor C3 actually appears net electric discharge.
Wherein, the control signal that the signal control module is sent to the switch module is high level signal or low level
Signal, further, the signal control module are selected to the switching molding by detecting the voltage at storage capacitor C3 two ends
Block exports high level signal or low level signal, such as, if the voltage at the storage capacitor C3 two ends is examined higher than a threshold value
Voltage is surveyed, then the signal control module exports low level signal to the switch module；, whereas if the storage capacitor C3
The voltage at two ends is less than the threshold test voltage, then the signal control module is believed to switch module output high level
Number；Specifically, can be by setting its divider resistance R1, R2, threshold test resistance for double hysteresis comparator chip IC L7665
R3 resistance (as shown in Figure 2) sets the threshold test voltage.In an embodiment of the present invention, the threshold test voltage
Be set to 5V, i.e., when the voltage at the storage capacitor C3 two ends is more than 5V, double hysteresis comparator chip IC L7665 output end
OUT1 exports low level signal, on the contrary, when the voltage at the storage capacitor C3 two ends is less than 5V, double hysteresis comparator chips
ICL7665 output end OUT1 output high level signals.
The effect of the switch module is high level signal or low electricity exactly by detect the output of signal control module
Ordinary mail number controls the break-make of itself, such as, if what the switch module detected the output of signal control module is low level
Signal, then switch module conducting (for switch chip CD4051, as pin 13 connect with pin O/I) entirely energy pipe
Manage circuit and be in channel status, so as to realize power supplies of the storage capacitor C3 for subsequent module；If on the contrary, described open
What pass module detected the output of signal control module is high level signal, then switch module disconnects, at whole energy management circuit
In open-circuit condition, now the storage capacitor C3, which only charges, does not power.
Further, described couple of hysteresis comparator chip IC L7665 and switch chip CD4051 startup power is respectively less than
Storage capacitor C3 power output.
In an embodiment of the present invention, the energy management module at least includes interrupted charging management chip.
Because most friction generators are output as discontinuous pulse electrical signal and power output is very low, energy storage
Electric capacity C3 both end voltage, which reaches, just starts electric discharge during 5V, and storage capacitor C3 output of the discharge power than friction generator
Power is much greater, and the electric discharge that factors above inevitably results in storage capacitor C3 is desultory, accordingly, it would be desirable to for energy storage
Electric capacity C3 discharge and recharge is managed.
Interrupted charging management chip is very harsh for the requirement of its minimum condition of work, i.e., must be in operating voltage and work
Make electric current all while reaching requirement, and ensure in the case of persistently giving, interrupted charging management chip ability normal work is no
Then, interrupted charging management chip can not only work, and can also consume the energy stored by storage capacitor C3 by chip leakage current
Totally, therefore the present invention chooses interrupted charging management chip and is managed for the discharge and recharge of the storage capacitor C3, Ji Jiangsuo
The electric energy for stating storage capacitor C3 releases is stored again, to ensure for the steady of the second energy storage module charging current
It is qualitative.
