摘要
介绍了一种采用ARM+CPLD结构作为控制核心,以AT89C52完成操作界面和显示处理单元,通过RS485进行数据通讯,通过三组反并联晶闸管作为控制元件,构成三相异步电动机软起动控制和保护系统。分析了硬件系统中各部分电路的功能和作用,并完成了硬件电路的设计与制作。
A controlling and protective system for three-phase AC asynchronous motor＇ s soft-starter was introduced, which was based on ARM＋CPLD as controlcore, AT89C52 as the user interface and display processing unit, data communication via RS485, and three anti-parallel thyristors as control element. The hardware composing of the system was analyzed. The hardware circuit design and production were completed.
