[0033] Further Figure 4 As shown, the power module includes a first power board and a second power board, the backplane includes a bus board, the input ends of the first power board and the second power board are respectively connected to 220V / 50Hz single-phase AC power, and the output slots of the first power board and the second power board are installed on the bus board for powering the communication gateway module, the integrated measurement and control module, the logic programming module, and the human-computer interaction HMI module. The first power board includes a rectifier chip U1, the AC_N pin and AC_L pin of the rectifier chip U1 are respectively connected to the AC1_N line and AC1_L line of 220V / 50Hz single-phase alternating current, and a surge transformer FV1 and a capacitor C1-1 are successively connected in parallel between the AC1_N line and the AC1_L line; the -Vo pin and the +Vo pin of the rectifier chip U1 are connected to the output slot, the -Vo pin is grounded, and the +Vo pin outputs the power supply, and the capacitor C1-2, a large current low voltage drop type Schottky diode V1-1, and a capacitor C1-3 are successively connected in parallel between the -Vo pin and the +Vo pin, and a diode V1-2 is connected in series on the +Vo pin wire, and the diode V1-2 is located between the large current low voltage drop type Schottky diode V1-1 and the capacitor C1-3, and the positive end of the diode V1-2 points to the +Vo pin, and the negative end thereof points to the output slot. The second power board has the same structure and the same arrangement as the first power board: the first power board includes a rectifier chip U2, the AC_N pin and AC_L pin of the rectifier chip U2 are respectively connected to the AC2_N line and AC2_L line of the 220V / 50Hz single-phase alternating current, and a surge transformer FV2 and a capacitor C2-1 are successively connected in parallel between the AC2_N line and the AC2_L line; the -Vo pin and the +Vo pin of the rectifier chip U2 are connected to the output slot, the -Vo pin is grounded, and the +Vo pin outputs the power supply, and the capacitor C2-2, a large current low voltage drop Schottky diode V2-1, and a capacitor C2-3 are successively connected in parallel between the -Vo pin and the +Vo pin, and a diode V2-2 is connected in series on the +Vo pin wire, and the diode V2-2 is located between the large current low voltage drop Schottky diode V2-1 and the capacitor C2-3, and the positive end of the diode V2-2 points to the +Vo pin, and the negative end thereof points to the output slot.

Since Vout1-VF is greater than Vout2-VF, the voltage value at the cathode of the diode V2-2 is higher than the voltage value Vout2 at the anode. The diode V2-2 is in the cut-off state, so the second power board is in the standby state and does not provide power to the device. At this time, if the power supply lines AC1_N and AC1_L of the first power board fail or the first power board cannot work normally, Vout1 will have no voltage. At this time, the second power board will immediately cut in to supply power to the device without gaps, ensuring that the device works normally and smoothly. Similarly, if the output slot 2 of the rectifier chip U2 is set as the main power supply module, and the output slot 1 of the rectifier chip U1 is the backup power supply module, it is only necessary to swap the resistance values ​​of the resistors R1 and R2.

[0035] Specifically, the information transmission, signal processing, control method, and control logic involved in this technical solution can be implemented using existing technologies.
