Problems solved by technology
[0002] At present, the traditional liquid level remote measurement technology uses pressure sensors and radar liquid level gauges to measure the liquid level, and the output is not processed. Therefore, when the liquid level fluctuates, the measurement output will fluctuate. At the same time, due to the poor accuracy of the sensor itself, the measurement has errors. ;The tank capacity output in the traditional liquid level telemetry is estimated; the traditional liquid level telemetry lacks data storage, and the storage time interval is uncertain; the liquid level telemetry and valve control systems are controlled separately, which is inconvenient to operate

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.
Description
technical field [0001] The invention relates to a liquid level remote measurement and valve control system. Background technique [0002] At present, the traditional liquid level remote measurement technology uses pressure sensors and radar liquid level gauges to measure the liquid level, and the output is not processed. Therefore, when the liquid level fluctuates, the measurement output will fluctuate. At the same time, due to the poor accuracy of the sensor itself, the measurement has errors. ;The tank volume output in the traditional liquid level telemetry is estimated; the traditional liquid level telemetry lacks data storage, and the storage time interval is uncertain; the liquid level telemetry and valve control systems are controlled separately, which is inconvenient to operate. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a liquid level remote measurement and valve control system with hig...
