and the energy storage circuit is connected with the amplifying circuit and used for storing electric quantity through the amplifying circuit.
In the energy storage circuit provided in the above embodiment, the spatial magnetic field energy collecting circuit is used to collect spatial magnetic field energy, convert the spatial magnetic field energy into electric energy and output the electric energy, and the amplifying circuit is used to amplify a signal to store electric quantity in the energy storage circuit, so as to provide power for a circuit that needs to be continuously powered, such as a clock memory circuit. Through the magnetic field energy of radiation in the make full use of space, the storage magnetic energy is stored and is the electric energy, realizes green energy recycle, can continuously be the outage of clock memory circuit simultaneously, has solved the higher problem of large capacity energy storage circuit cost among the correlation technique, and the circuit realizes that the cost is lower, and the volume is less simultaneously.
As shown in fig. 1, the spatial magnetic field energy collecting circuit includes: an extension antenna T1, LC tuning circuit; the LC tuning circuit comprises a capacitor C1 and an inductor L which are connected in series, wherein the capacitor C1 is connected with the output end of the extension antenna T1, and the inductor L is used for outputting a voltage signal. Wherein, L is high-precision high-frequency inductance, C1 is high-precision polyester film capacitance, and LC resonance frequency can be calculated by the following formula:
in order to realize the effect that LC resonance frequency diversification can be matched, the invention sets the following three modes to adjust resonance parameters:
the first method is as follows: the capacitance C1 in the circuit can be selected in various ways, and the number of the capacitances can be adjusted by connecting a plurality of capacitances in parallel to achieve the purpose of adjusting resonance parameters; the inductance in the circuit can be selected in various ways, and the purpose of adjusting resonance parameters can be achieved by connecting a plurality of inductances in parallel or reserving the inductances connected in series (short-circuit inductances are firstly connected in the circuit, and short-circuit wires are removed when parameters need to be adjusted), and adjusting the number of the inductances.
The second method comprises the following steps: the sliding variable capacitor and the sliding variable sensor are adopted, and different capacitance values and different inductance values are selected through the sliding sheet.
The third method comprises the following steps: the capacitance and the inductance are placed in the temperature control box by utilizing the influence of the temperature on the capacitance parameters and the inductance parameters, and the resonance parameters of the LC tuning circuit are further adjusted by adjusting the capacitance value of the capacitance C1 and the inductance value of the inductance L through adjusting the temperature in the temperature control box.
In a preferred embodiment of the invention, the amplifying circuit is a half-wave voltage doubling circuit, the voltage multiple of which is one or more times. Usually, the energy collected by the spatial magnetic field energy collecting circuit is weak, and in order to realize that the small energy is gathered into the usable power supply energy, the voltage doubling circuit needs to be designed with a multistage voltage doubling circuit.
Fig. 1 shows a half-wave voltage doubling circuit with a factor of 4, and as shown in fig. 1, the half-wave voltage doubling circuit includes: the capacitors C2, C3, C4 and C5, the diodes D1, D2, D3, D4 and the capacitor C2 are respectively connected with the negative electrodes of the inductor L and the diode D1, and the like.

Meanwhile, in order to stabilize the voltage of the power supply, a voltage stabilizing diode D6 is added and connected in parallel with the energy storage capacitor for stabilizing the output voltage Vout of the energy storage capacitor. Diodes of different voltage grades are selected according to different voltage requirements, but attention needs to be paid to the fact that the voltage used by the circuit cannot exceed the highest output voltage of the voltage doubling circuit.
