中文摘要：

针对化工过程对安全性面临的问题与挑战，以感知控制论（Perceptual Control Theory,PCT）的层次性和信息处理与环境交互特性为科学基础，提出一种将信息物理融合系统（cyber-physical system，CPS）的概念和感知控制论相结合的PC—CPS模型。以此为基础，考虑化工过程的特点，构建化工过程安全运行的信息物理融合系统模型。该系统模型具有实时监测、信息共享、故障诊断、故障预测和基于知识的决策建议等功能，并对物理空间感知技术、信息空间融合技术及系统模型的实时性等关键技术进行分析。最后，通过环己烷无催化氧化过程的信息物理融合监控系统为例，描述并验证该系统模型可以用于化工过程，改善了系统运行的安全性。

英文摘要：

Aiming at the problem and challenges of safety for chemical process, based on the levels and information processing and environmental interaction of Perceptual Control Theory （PCT）, PC-CPS model which is incorporated with Cyber-Physical System （CPS） concepts and characteristics of PCT is proposed in this paper. A cyber-physical system model for the safe operation of chemical processes combined with the characteristics of chemical processes is represented. The proposed model has the functions of an ability of sensing real-time monitoring, information sharing, fault diagnosis, fault prediction, and making-decision suggestions by means of the knowledge. Three key technologies which are perception of physical space, information fusion of cyber space and real-time model are described in detailed, Finally. It is exampled by a uncatalysed oxidation of cyclohexane Cyber-Physical monitoring system. That has showed the proposed model which is verificated can be used in chemical processes to improve security.
