摘要
随着我国异戊橡胶消耗量及需求量的逐渐增加,异戊橡胶生产过程自动化水平的提高就显得势在必行。由于橡胶生产行业具有生产装置体积庞大,设备管线错综复杂,生产过程连续性强等特点,所以又对生产过程中的每套装置的自动化控制水平有着严格的要求。
     本文从实际工程出发,针对某异戊橡胶生产厂里的一套联合装置,进行自动控制系统设计。从低成本自动化的模式出发,设计了一种以IPC工控机、研华公司的ADAM4000系列远端数据采集模块、北京亚控科技发展有限公司的组态王6.53软件以及以传感器技术为基础构成的异戊橡胶生产中的联合装置的自动控制系统。通过不同的传感器采集数据并转化为ADAM4000模块可以接受的信号,采集后的数据通过RS485传输到工控机。工控机通过组态王对数据进行分析处理,并实时显示数据,为异戊橡胶生产过程中的联合装置的正常运行提供保障。在该套控制系统中,还添加了特殊的逻辑控制功能,通过组态王脚本程序的编写,实现符合生产需要的逻辑控制。将电气上未能实现的逻辑控制,通过在上位工控机的组态王软件来实现。另外,将上位监控系统与DCS设备相连,完成数据通讯功能,实现工厂的集中显示,分散控制功能。总之,该套自动控制系统,不仅实现方法简单,而且具有很高的使用价值和较高的理论意义。
With the increasing of the consumption and demand of isoprene rubber in our country, increasing the automation level of isoprene rubber production process becomes more and more imperative. Because the rubber production equipment is large and the pipeline is complex, and the production process is continous and so on, it has strict requirements on each equipment’s automation level in the production process.
     This paper is from the actual project to design a automation control system for a united device in a isoprene rubber production factory. It started from the low-cost automated mode to design a kind of automation control system for the isoprene rubber united device. This system used IPC, Advatech’s ADAM4000 series remote data acquisition modules, Beijing Asia Control Technology Development Co., Ltd.’s Configuration software—kingview6.53, and based of the sensor technology. It can collect signal from the different sensor and transform them to the ADAM-4000 module‘s kind. And then the gathering data is sent to control machine by RS485. The IPC carry on the data analysis processing through the configuration software and display the real time data, it can also provide the safeguard for the isoprene rubber production process in the united device’s normal operation. In this control system, it also increased the special logical control function. Through the configuration software script procedure’s compilation, it realized the proper logical control which the production needs but can not be realized through the electricity technology. Besides, in this system, the upper computer is connected with the DCS equipment to complete the data communication function and realize the factory centralism to demonstrate, dispersion control function. In brief, this automation control system is not only simple to realize and having very high use value and high theory significance.
