嵌入式PLC系统容错软件的设计

Design of the Fault-tolerance Software of Embedded PLC Systems

本文论述了编写嵌入式容错软件的原则;根据这些原则,介绍了基于8051系列处理器的嵌入式PLC设计中编写容错软件的方法。这些原则和方法有利于提高嵌入式PLC的软件可靠性,亦可用其它嵌入式容错软件的编写。

This paper discussed the principle of designing the fault-tolerance software of the embedded system. In accordance with these principles, the methods and technologies of designing the fault-tolerance software of the embedded PLC systems based on 8051 MCU are introduced. These principles and methods can be used to promote the reliability of the embedded PLC and also be used in other embedded systems.
