Valve detection device and operating method thereof

A valve control device, comprising:

• a driving circuit, comprising:
• a plurality of solenoid valve terminals which are configured to connect to a plurality of solenoid valves;
• a sensing terminal;
• a switch having at least one input terminal and a plurality of output terminals which are electronically coupled to the plurality of solenoid valve terminals, respectively, wherein the switch connects the at least one input terminal with one of the plurality of output terminals according to a switch signal;
• a first sub-circuit electronically coupled to the at least one input terminal of the switch;
• and
• a second sub-circuit electronically coupled to the at least one input terminal of the switch;
• a microcontroller unit electronically coupled to the driving circuit, sending a first set of the control signals to the driving circuit and sending a detection signal;
• and
• a microprocessor electronically coupled to the driving circuit and the microcontroller unit, repeatedly sensing a voltage level at the sensing terminal when the detection signal is sent to one of the solenoid valve terminals and obtaining a sensing result accordingly until all the sensing results of the solenoid valve terminals are obtained, and sending the switch signal to the switch,
• wherein the first sub-circuit is disabled in response to the first set of the control signals.

A non-transitory computer-readable storage medium storing a program, causing a valve control device to perform a valve control process, wherein the valve control device comprises a driving circuit and the driving circuit comprises a plurality of solenoid valve terminals and a sensing terminal, said valve control process comprising:

• sending a first set of the control signals to the driving circuit;
• sending a detection signal;
• sensing a voltage level at the sensing terminal when the detection signal is sent to one of the solenoid valve terminals and obtaining a sensing result accordingly;
• and
• repeating the step of sensing the voltage level until all the sensing results of the solenoid valve terminals are obtained,
• wherein a first sub-circuit of the driving circuit is disabled in response to the first set of the control signals.
