60kV 7000A换流阀功能试验回路的HMI设计

60kV 7000A The HMI Design of the Functional Test Circuit of the Converter Valve

本文对组态软件界面设计时的经验和技巧做了说明,因为设计出友好的、安全的、操作性强的人机界面需要丰富的经验结合技巧才能实现。文中提到通过访问外部数据库通过查表法实现SER报警的新方法。并且根据组态软件的特性详细说明了通过模拟量替换开关量的方法来节约HMI组态软件中应用的I/O通信点的方法,并给出了具体实现代码。还对HMI组态软件的一些概念,及其基本原理进行了阐述,并对软件内部数据处理流程进行了剖析。

This chapter based on the actual work, illustrates the experience and techniques of configuration software interface design. Because designing a friendly, safe, and user-friendly HMI requires a wealth of experience combined with skill. Mentioned in the article through the visit to the external database through the look-up method to achieve a new method of SER alarm, and the specific implementation code is given. According to the characteristics of the configuration software on the market, one way that replace analog data points by switch data points to saving the I/O data points is described in detail. Also introduces some concepts of HMI configuration software, The basic principle of common HMI configuration software is discussed and the data processing flow of software is analyzed.
