基于ARM和CPLD可编程工业控制器的设计

Design of Programmable Industry Controller Based on ARM and CPLD

采用基于APM和CPLD结合的方式,设计一款可编程工业控制器,既能满足实验室教学要求,又能直接应用现场工业控制。文章阐述了控制器的几大基本模块,以APM为主处理器,用CPLD作为扩展接口的桥接器,扩展出ISA总线接口,用来连接各种数据采集和控制模块。实验表明,该设计具有很大的应用前景。

Based on ARM and CPLD,an embedded industrial controller is designed,it not only meets the demands of laboratory teaching,but also directly applicable for the industrial control.The paper expounds several basic modules of the controller,such as ARM as the mainly processor,and with CPLD as a bridge expansion joints,in order to be an ISA Bus interface expansion which could be used as various data collection and modulation controls. It indicates that the design has a great practical value.
