摘　　要：针对SDH光通信设备的高可靠性和高实时性需求,设计了一种采用μC/OS-Ⅱ操作系统的嵌入式实现方案。该方案利用μC/OS-Ⅱ灵活的多任务调度和任务间同步机制,建立了一种基于环形缓冲区和信号量机制的多任务间串口通信模型。通过对任务功能的合理划分和任务优先级设置,该嵌入式系统满足了SDH光通信设备的应用需求。In order to fulfill the high reliability and real-time requirement that the SDH optical communication device needs in practical design, a scheme is proposed by using embedded system based on μC/OS-Ⅱ. Tak- ing advan- tage of the excellent multitask scheduling and synchronization technology of μC/OS-Ⅱ, the scheme establishes a serial communication model which based on a ring buffer and semaphore mechanism. By rea- sonable division of the task function and the priority settings of the tasks, the system designed implements the practical requirement of SDH optical communication.
