基于FBD语言的嵌入式控制软件的研究与实现

Research and Implementation of FBD-based Embedded Control Software

本文首先介绍了基于嵌入式计算机的开放式软PLC的发展趋势,然后研究应用VisualC++开发的基于FBD语言的嵌入式控制软件,并说明了软件核心框架和功能模块,最后以PID控制模块为例详细介绍了功能模块的程序实现、调试和使用方法。实践证明,该软件与嵌入式计算机结合,可以快速、方便地开发成各种用于现场数据采集、处理和过程控制的设备。

This paper presents a kind of embedded control software which is based FBD language and developed with C++,and lastly describes the implementation,debug and usage of function blocks,with PID control module as a example.The practical results show that this software,combined with embedded computer,can quickly and easily be developed into various systems used for field data acquisition and processing,as well as process control.
