[0066] Continue to see Figure 3 Optionally, the first power switch 120 includes a contact switch corresponding to the relay KA11, and the contact switch corresponding to the relay KA11 is controlled by the coil of the corresponding relay KA11.
[0067] Figure 4 A partial structural diagram of a control module provided by an embodiment of the utility model.

The relay control unit includes an intermediate relay coil 140 and an intermediate relay contact switch. The first end of the intermediate relay coil 140 is connected to the programmable logic control unit 130, and the second end of the intermediate relay coil 140 is connected to the power supply voltage; the programmable logic control unit 130 controls the on and off of the intermediate relay coil 140; the intermediate relay contact switch is connected to the interface conversion unit 310, and the intermediate relay contact switch switches the connection relationship of the interface conversion unit 310.
