摘要
介绍在基于51系列微控制器的分布式监控系统中,为满足系统的实时性要求,提高系统的稳定性和可靠性,将嵌入式实时操作系统μC/OS-Ⅱ用于微控制器软件设计,将系统各个功能模块划分成不同优先级的任务,采用多任务占先式运行机制代替传统的单任务顺序运行机制,满足了系统的实时性要求,同时使系统的可靠性和可维护性都得到了很大的提高。
In order to satisfy the required real-time performance and improve the reliability and stability of the system, the embedded RTOS μC/OS- Ⅱ is used for software design in distributed monitoring and control system based on 51 series microcontrollers. The functional modules in the system are divided into many tasks with different priorities, the multi-tasking anticipated operation mechanism is used to replace traditional single task sequential operation mechanism. Thus the requirement of real-time performance is satisfied and the reliability and maintainability of the system are improved greatly.
