过程监测与故障诊断是化工过程工程中的一项重要任务,是保证生产过程安全运行、降低废品率的重要环节。本文在分析各种诊断方法的基础上,结合数据分析、专家系统、模糊逻辑以及面向对象分析等技术,提出并开发了一个化工过程实时监测与模糊诊断系统。该系统由数据校正、过程监测和模糊专家系统三部分组成,采用开放式结构,具有良好的易维护性和可扩充性。
Process monitoring and fault diagnosis are an important task in the chemical process engineering. They are an important part of ensuring the safe operation of the production process and reducing the reject rate. Based on the analysis of various diagnostic methods, combined with data analysis, expert system, fuzzy logic and object-oriented analysis, this paper proposes and develops a real-time monitoring and fuzzy diagnosis system of chemical process. The system consists of data correction, process monitoring and fuzzy expert system composed of three parts, using open structure, with good maintainability and scalability.
