In order to effectively address the problems of low level control accuracy and low automation caused by the reliance on automatic control mechanisms to construct control circuits in previous paper-making liquid level control systems,this paper focuses on revitalizing the liquid level control system with embedded technology,and in response to the black liquid level control requirements of the alkali recovery and evaporation section of pulp and paper making,a black liquid level automatic control system is designed based on a 52 microcontroller and ultrasonic sensors.The system test results show that the liquid level control system combining microcontroller and sensor has high accuracy,automation,and safety stability.It can not only fully adapt to the current pursuit of unmanned and efficient paper-making industry production system,but also be widely promoted and applied in other industrial fields.
