[0053] Among them, the pulse generator comprises the timer U2, the resistors R1 and R2, the diodes D1 and D2, the general capacitor C2, and the polarized capacitor C1.

[0054] Specifically, pin 2 of the NOT gate U1 and the cathode of the diode D3 are connected, and a COM IN input end is arranged at the position; pin 3 of the NOT gate U1 is grounded, pin 5 is connected to a power supply, pin 4 of the NOT gate U1, pin 4 of the pulse generator U2 and pin 1 of the counter U3 are connected; one end of the resistor R2 and pin 8 of the pulse generator U2 are connected and connected to the power supply, the other end of the resistor R2, the anode of the diode D1, one end of the resistor R1 and pin 7 of the pulse generator U2 are connected, the other end of the resistor R1 and the cathode of the diode D2 are connected, the cathode of the diode D1, the anode of the diode D2, pin 2 of the pulse generator U2, pin 6 of the pulse generator U2 and the positive electrode of the polarized capacitor C1 are connected, pin 5 of the pulse generator U2 and one end of the general capacitor C2 are connected, the other end of the general capacitor C2, pin 1 of the pulse generator U2 and the negative electrode of the polarized capacitor C1 are connected and grounded; pin 3 of the pulse generator U2 and pin 2 of the counter U3 are connected, pin 7 of the counter U3, pin 9 of the counter U3, pin 10 of the counter U3, pin 16 of the counter U3 and one end of the resistor R3 are connected and connected to the power supply, pin 3 of the counter U3, pin 4 of the counter U3, pin 5 of the counter U3, pin 6 of the counter U3, pin 8 of the counter U3 and the other end of the resistor R5 are connected and grounded, pin 15 of the counter U3 and one end of the resistor R4 are connected, the other end of the resistor R4 and the base of the transistor Q1 are connected, the collector of the transistor Q1 and the other end of the resistor R3 are connected, the emitter of the transistor Q1, the other end of the resistor R5 and the anode of the diode D3 are connected and a COM OUT output end is arranged at the position.
