AI Technical Summary

Technical Problem

In the current PTA production process, the quality monitoring methods are outdated and cannot track the quality-influencing factors at each stage in real time, leading to misjudgments or omissions. This makes it difficult to achieve accurate quality anomaly monitoring and parameter optimization throughout the entire process, affecting production efficiency and costs.

Method used

Design a PTA quality anomaly monitoring system, including a production data acquisition module, a quality index function construction module, an anomaly envelope determination module, and a quality parameter optimization module. By acquiring data in real time, a multi-dimensional quality coordinate system is constructed, the minimum quality anomaly envelope function is determined, and this function is used as a constraint to optimize the threshold of key quality indicators. Combined with quality field analysis and parameter coupling estimation, the system realizes full-process quality monitoring and dynamic optimization.

Benefits of technology

It enables real-time monitoring and dynamic optimization of the entire PTA production process, allowing for timely detection and location of quality issues, reduction of defective products, improvement of product quality stability and pass rate, reduction of raw material and energy waste, and enhancement of production efficiency.
