Assuming that the control switch SCC2 is activated, the resonant frequency generated by the first switching circuit is F1, which is represented by the information symbol 1. Suppose When the control switch SCC3 is activated, the resonant frequency generated by the second switch circuit is F2, which is represented by the information symbol 2. Suppose the control switch SCC4 is activated, and the resonant frequency generated by the second switch circuit is F3, which is represented by the information symbol 3. It is assumed that the control switches are activated at the same time. SCC1, SCC2, SCC3 and SCC4, the resonant frequency generated by the total switch circuit is F4, which is represented by the information symbol 4, and so on, the control switch can be activated by combination to generate more resonant frequencies and express more consistent information. Information is transmitted through information symbols such as 0, 1, 2, 3, and 4, and so on. Multiple switch circuits can be set to control the generated resonant frequency to transmit various information states.

所述零线端N和所述火线端L之间串接有电阻R6、电阻R8和电阻R10,所述电阻R8和所述电阻R10的共接端依次通过电阻R9和电容C2接地,所述电阻R9和所述电容C2的共接端与所述微控制器M1的10管脚电性连接;A resistor R6, a resistor R8 and a resistor R10 are connected in series between the neutral wire terminal N and the live wire terminal L. The common terminal of the resistor R8 and the resistor R10 is grounded through the resistor R9 and the capacitor C2 in sequence. The common terminal of the resistor R9 and the capacitor C2 is electrically connected to the 10 pin of the microcontroller M1;

作为上述技术方案的进一步优选的技术方案,所述充电周期,从交流电网选取一个时间点T0,时间点T0所对应的相位角为Ф0,所述零线端N和所述火线端L之间的电压为U,在所述微控制器M1的14管脚(SW1)施加脉冲信号以此打开所述控制开关SC1,交流电压为U1:As a further preferred technical solution of the above technical solution, in the charging cycle, a time point T0 is selected from the AC power grid, and the phase angle corresponding to the time point T0 is Φ0, between the neutral line terminal N and the live wire terminal L The voltage is U, and a pulse signal is applied to pin 14 (SW1) of the microcontroller M1 to open the control switch SC1, and the AC voltage is U1:

U1=U*sin(Ф0)。U1=U*sin(Ф0).

优选地,交流电压U1通过所述电感L1对所述电容C1充电,流过所述电感L1的电流逐步增大,然后逐步减小,所述电容C1上的电压逐步增大,当时间达到T1,流过所述电感L1的电流等于零,所述电容C1上的电压达到最大值Uc1m,控制开关SC1自动关断。由于电路的损耗和交流电压的相位角也在变化,所以电容C1上的电压最大值Uc1m无法达到2倍的U,通常会比2倍的U小一点。Preferably, the AC voltage U1 charges the capacitor C1 through the inductor L1, the current flowing through the inductor L1 gradually increases, and then gradually decreases, and the voltage on the capacitor C1 gradually increases, and when the time reaches T1 , the current flowing through the inductor L1 is equal to zero, the voltage on the capacitor C1 reaches the maximum value Uc1m, and the control switch SC1 is automatically turned off. Since the loss of the circuit and the phase angle of the AC voltage are also changing, the maximum voltage Uc1m on the capacitor C1 cannot reach 2 times U, and is usually a little smaller than 2 times U.

作为上述技术方案的进一步优选的技术方案,所述保持周期,电容C1上的电压保持在最大值Uc1m。As a further preferred technical solution of the above technical solution, in the holding period, the voltage on the capacitor C1 is kept at the maximum value Uc1m.

优选地,流过所述电感L1的电流逐步增大,然后逐步减小,当电流等于零的时候,控制开关SC1关闭,电容C1充入与充电周期相反方向的电荷。Preferably, the current flowing through the inductor L1 is gradually increased and then gradually decreased. When the current is equal to zero, the control switch SC1 is turned off, and the capacitor C1 is charged with charges in the opposite direction of the charging cycle.

所述往复振荡周期,如果继续调制所述控制开关SC1处于打开状态,则持续产生M个振荡周期(M取决于电路的损耗、谐振频率以及交流电网的频率)。In the reciprocating oscillation period, if the control switch SC1 is continuously modulated to be in an open state, M oscillation periods are continuously generated (M depends on the loss of the circuit, the resonance frequency and the frequency of the AC grid).

优选地,反复控制控制开关,即可产生谐振电流,在交流电网下,电路的谐振频率由LC决定,谐振电流也相比被动模式提高很多。Preferably, the resonant current can be generated by repeatedly controlling the control switch. In the AC power grid, the resonant frequency of the circuit is determined by LC, and the resonant current is much higher than that in the passive mode.
