基于Web的工业上位机系统开发

Web-based Industrial Master Computer System Development

随着工业自动化技术进步,工厂系统的设备越来越多,设备状态实时监控、设备复杂逻辑操作、配方工艺生产安排、权限管理、数据统计报表等都需要由上位机来执行。上位机就是在计算机端运行与PLC交互通信的控制软件。大多数语言都可以开发上位机,但是不同语言和平台实现的上位机在通用性、运行速度、界面美观、开发效率、可实现功能、安全性上有较大差异。通过开发多种语言平台的上位机进行比较,本文主要对WNMP(Windows+Nginx+MySQL+PHP)环境下的上位机优点及实现方法进行介绍。

With the advancement of industrial automation technology,there are more equipment in the factory system.Real-time monitoring of equipment status,complex logic operation of equipment,production arrangement of recipe process,authority management,data statistics and reports need to be executed by the master computer.The master computer is the control software that runs on the computer and communicates with the PLC interactively.Most languages can be used to develop the master computer,but the mater computer implemented by different languages and platforms has great differences in versatility,running speed,beautiful interface,development efficiency,realizable functions,and security.Through the comparison of the master computer developed on multiple language platforms,this article mainly introduces the advantages and implementation methods of the master computer under the WNMP(Windows+Nginx+MySQL+PHP)environment.
