AI Technical Summary

Technical Problem

In the prior art, the temperature fluctuates greatly in the production process of water-based coatings, and the PID control and regulation response is slow, resulting in untimely regulation in the event of temperature abnormality and poor temperature consistency.

Method used

Using an intelligent monitoring method based on data analysis, the temperature and concentration data in the reactor are periodically obtained, the temperature change period segment is divided by the extreme value of the temperature data, the temperature data deviation index and the chemical reaction deviation index are determined, and the temperature PID control and regulation are combined with the two to determine the degree of temperature adjustment and the necessity of regulation, and the temperature PID control and regulation in the reactor is carried out.

Benefits of technology

It effectively avoids the overall regulation and slow response caused by PID regulation based solely on temperature deviations, ensures that the chemical reaction is always in the best state, and ensures the temperature consistency of the entire production process.
