基于组态王的油品罐区监视系统设计

Design of a Monitoring System for an Oilcan Based on Kingview

监视系统是工业生产的必备系统之一 ,它对于生产的决策和安全有着重要的作用。以前往往用计算机语言去开发比较大型的自动化软件 ,这种方法不仅开发周期长 ,而且难度大 ,通用性也不好。在现代工业生产中 ,取之以代的是工控组态软件 ,其中组态王是国内组态软件中较为优秀的一个。介绍了用组态王来设计油罐的温度和液位的监视系统 ,重点介绍了对温度和液位信号的数据处理方法。

A monitoring system is indispensable for industrial production and it can give engineers more and more time and energy to make appropriate control decision, to avoid the decision mistakes and to realize in time alarming. Previously a great deal of work has to be done in writing these automation softwares and softwares written in this way are not good for wide use and liability. However a configuration software can solve above problems well. Temperature and oil level in the oilcan system are two important parameters that need to be monitored to guarantee the safety of industrial process. In this paper the properties about configuration softwares and the Kingview software are introduced firstly, then the design to implement an oilcan monitoring system with the Kingview is presented. The main function of this system which is made up of data sampling and data processing is to monitor the temperature and the oil level. Therefore the data processing about the two parameters is studied in detail.
