摘要：带搅拌釜式反应器（Continuous Stirred Tank Reactor, CSTR）是一种复杂的非线性化学反应器，随着生产的发展，广泛应用于化工、发酵、石油生产、生物制药等工业生产过程中，成为发展国民经济的重要化工设备之一。结合控制要求，通过分析工艺流程，本论文设计了串级PID分程控制方案。方案选定后，进行了硬件和软件的选择。硬件上选用西门子公司的S7-300 PLC，并用相应的STEP7软件编程。然后采用西门子开发的组态王组态软件设计监控画面，并利用Winccflexible软件对系统进行了仿真。HMI是（Human Machine Interface ）的缩写，“人机接口”，也叫人机界面。人机界面（又称用户界面或使用者界面）是系统和用户之间进行交流和信息交换的媒介，它实现信息的内部形式与人类可以接受形式之间的转换。9096

Continuous stirred tank reactor（CSTR）control system development（HMI）
Abstract: Continuous Stirred Tank Reactor is a kind of complex non-linear chemical reactor, with the development of production, are widely used in chemical industry, fermentation, oil production, biological, pharmaceutical and other industrial production process, become one of the important chemical equipment development of the national economy. Combined with the control requirements, through the analysis process, this paper design the cascade PID process control plan. Scheme is selected, the selection of hardware and software. Hardware and the use of Siemens S7-300 PLC, and the corresponding STEP7 programming software. Then use kingview configuration software developed by Siemens design monitoring screen, and use the winccflexible software on the system are simulated.The abbreviation of HMI is the Human Machine Interface, man-machine Interface, also known as the man-machine Interface. Man-machine interface (also known as the user interface or the user interface) is the interaction between system and user and the information exchange medium, it can realize the internal form and human accept form conversion between.
Keywords: stirring tank reactor, Siemens S7-300 PLC and HMI
