摘　　要：以一类常见的化学反应器——连续搅拌反应釜(CSTR)为虚拟仿真对象,提出一种基于化学反应器装置机理模型的开放式虚拟仿真系统开发方法。首先,使用机理分析法建立数学模型;然后,在LabVIEW软件中构建工艺流程界面,并基于四阶龙格-库塔法编制虚拟仿真程序;进一步,利用共享变量引擎将虚拟装置数据发布到OPC Server中,使虚拟系统具有良好的开放性。以Matlab软件为例,说明了共享数据的调用过程。该虚拟仿真系统不但能够较好地模拟CSTR的工艺特性,而且其数据的开放性有助于学生自行设计控制方案、自主开展创新性实验研究。This paper proposes an opening virtual simulation system design method based on the chemical reactor mechanism model. One common chemical reactor referred to as continuous stirred tank reactor （CSTR） is used as the simulation objective. Firstly, its mathematical models are built using the mechanism analysis technique. Then the process flow diagram is constructed by LabVIEW software and the simulation programs are established using the four-order Runge-Kutta method. With the help of shared variable engine （SVE）, the simulation data are deployed to OPC server, which leads to good system open performances. Matlab is used to illustrate the calling procedure of sharing data. This system can simulate the CSTR device characteristics well. Also the openness of simulation helps students to design their own control strategy and provides a platform for the innovative experiment.
