When the base of the transistor Q is at a high level, the transistor Q is turned on and the relay KA works. When the base of the transistor Q is at a low level, the transistor Q is turned off and the relay KA does not work. The diode D1 is a freewheeling diode used to release energy on the coil of the relay KA.

[0033] Specifically, the meter valve module 4 also includes a resistor R3 and 220V mains power;

[0034] The 220V mains electricity is used to provide power supply. The resistor R3, the solenoid valve and the switch S are connected in series. When the switch S is closed, the solenoid valve works and the resistor R3 is a sampling resistor.

The transmission content includes operating data, control instructions and alarm information, etc. The main control module 1 controls the on and off of the transistor Q in the control module 3 by outputting high and low levels, and then controls the working state of the solenoid valve in the meter valve module 4. The monitoring module 5 determines whether the solenoid valve is working normally by detecting the current when the solenoid valve is working. When the working current is within the normal range, the monitoring module 5 outputs a low level, otherwise it outputs a high level, which eliminates the process of analog-to-digital conversion, reduces costs, and is more practical.
