基于ARM嵌入式系统的微型智能可编程控制器

Micro Intelligent Programmable Logic Controller with ARM Embedded System

微型智能可编程逻辑控制器(PLC)目前越来越广泛地应用到电力系统的各种控制系统中,针对当前国内外微型智能PLC主要以传统的8位、16位单片机为处理器的不足,研制了一种基于ARM嵌入式处理器的微型智能PLC。介绍了系统的体系结构,给出了基于AT91SAM9260芯片的PLC硬件系统设计方案和基于VxWorks嵌入式实时操作系统的软件设计方案。

Micro intelligent programmable logic controller （PLC） has been widely used in various control system of electric power system. However the current micro intelligent PLC still adopts eight bites or sixteen bites single-chip microcomputer as its processor. To overcome its deficiency,an ARM embedded processor-based micro intelligent PLC is designed. The system framework is present concisely. The hardware design based on AT91SAM9260 chip and the software design with the embedded real-time operating system VxWorks,are introduced in detail.
