Abstract

The embodiment of the invention relates to the field of automatic control, and discloses an embedded intelligent liquid level detection control system which is used for controlling the liquid level height of a target container to be kept at a preset height. The embedded intelligent liquid level detection control device comprises a detection device which is installed above a target container and used for detecting the liquid level height of the target container and generating a corresponding liquid level height signal; a comparator, used for receiving and processing a preset signal and a liquidlevel height signal which are set in advance and generating a comparison signal; a control device, used for receiving and processing the comparison signal and generating a control signal; an execution device, used for receiving the control signal and changing the liquid level height of the target container according to the control signal; wherein the detection device is an ultrasonic range finder. The embedded intelligent liquid level detection control system has the advantages of being long in service life and capable of reducing manual labor.

Description

technical field [0001] The embodiments of the present invention relate to the field of automatic control, in particular to an embedded intelligent liquid level detection and control system. Background technique [0002] At present, in many industrial production systems in our country, it is necessary to monitor the liquid level or material level of the system, especially for the measurement of the liquid level of corrosive liquid. To detect the liquid level, the electrode is immersed in the liquid for a long time, which is easily corroded, electrolyzed, and loses sensitivity. Therefore, the corrosion resistance of the test equipment is high. [0003] There are still buildings in residential quarters in my country. The tap water supply system mainly uses high-tower water supply, that is, a reservoir is built on the roof of the building or on an additional high-tower to ensure the constant water pressure of the user. At present, most of the residential quarters adopt the meth...
