Control system for liquid level remote surveying and valves

The invention discloses a control system for liquid level remote surveying and valves. The control system comprises a man-machine interface. The man-machine interface is connected with a controller. The controller controls a liquid level remote surveying subsystem, a valve water pump control subsystem, an alarm control subsystem and a database storage subsystem. The liquid level remote surveying subsystem comprises a pressure sensor, a radar liquid level meter, a thermocouple and a floating ball sensor. The valve water pump control subsystem comprises the electromagnetic valve, the ball valve, a water pump and the butterfly valve. The alarm control subsystem comprises a temperature alarm, a liquid level ultralimit and low-limit alarm, a high-voltage alarm and a valve abnormity alarm. The database storage subsystem comprises a sqlite database. The control system has the advantages of being high in precision and convenient to operate.
