【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。更多还原

【Abstract】 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.更多还原
