摘　　要：针对在嵌入式系统中采用“线性”程序设计方法带来的实时性差和扩展性不高的问题,通过在一个嵌入式数据采集系统中移植嵌入式实时操作系统uC/OS-Ⅱ,在分析了在实时操作系统uC/OS-Ⅱ下,确定了系统各个任务的优先级并实现了任务间的相互切换,提高了系统运行实时性和稳定性;数据采集系统移植了传输效率更高的UDP/IP协议栈,实现了系统的网络通信功能;实验表明, 数据采集系统在移植了uC/OS-Ⅱ具有良好的实时性和扩展性并且运行稳定。An embedded Real-time OS is presented for a data collection system, uC/OS-Ⅱ is used to overcome the problem of bad Real-time and expansibility due to adopt the tradition linearity design. After conformed the PRI of all kind tasks of system and realized the switch of task , The data collection system has high real-time performance and stable running environment. Due to UDP/IP suit protocol has been replanted in the system, the data collection system realized net communications.
