Embodiment Construction
[0016] Such as figure 1 As shown, the present invention is used for the computer to automatically manage the wiring socket of household electronic appliances. The first pin CD, the sixth pin DSR, the eighth pin CTS and the ninth pin RI of the RS232C interface 8 respectively pass through a pull-up resistor R1, R2 , R3, and R4 are connected to the output positive pole of the regulated power supply circuit. These four pins and the output negative pole of the power supply circuit respectively constitute four pairs of terminals of the sensor Rs1, Rs2, Rs3, and Rs4 interfaces. The fourth pin DTR of the RS232C interface 8, the fourth pin Each of the seven-pin RTS is connected to the signal input terminal of 1-way AC electronic switch circuit and 1-way weak current electronic switch circuit through an isolation diode D3, D4, and the AC input terminal of the voltage-stabilizing power supply circuit 5 is connected to the lightning protection and surge protection circuit 51 Parallel conn...
