Abstract:

For acidic liquid circulating water concentration fluctuations and neutralization reactions serious lag and other issues, this paper puts forward a MCS-51 microcontroller core circulating water quality analysis control system. Article explains the process control system circulating water, cascade control, and incremental PID algorithm application. Introduced the hardware structure of the control system and peripheral hardware circuit, design a kind of fast, stable PH value control system. Compared to the traditional analysis of the quality of circulating water control system, the presented system has strong data processing ability, but also has small volume and low power consumption, according to characteristics of simplicity.And through the test under different conditions,it can finish a cycle in the 20s to 25s neutralization reaction.The actual test results showed that:rational design of each module, the entire system is stable, fast response.
