基于RT-Linux的嵌入式PLC设计及实现

The Design and Realization an Embedded Programmable Logical Control Structure Based on RT-Linux Operating System

以工控机为硬件平台,利用RT-L inux的实时多任务调度机制,构造了基于RT-L inux的数控系统嵌入式PLC结构,介绍了系统的软硬件体系以及其实现方法。

An embedded programmable logical control （PLC） structure of a computer numerical control （CNC） system was set up based on RT - Linux operating system and industrial PC platform. The software and hardware configuration of PLC was given. Corresponding realization measures, and the real - time multitasking dispatch mechanism of RT - Linux were discussed.
