摘　　要：网络通信设备如加固型路由器、台式或背负式指挥终端网口、V35/HDSL等通过以太网接口进行数据收发。设计开发网络设备检测仪对出现故障的设备或链路进行检测和定位。采用32位ARM微处理器同时引入嵌入式操作系统uCOS-II,满足多任务实时性要求。并设计监视任务实时监视系统的正常运行,使系统的可靠性和稳定性得到了较好的解决。Network communication equipments, such as reinforced routers, desktop or backpack command terminal ports and V35/HDSL and so on, send and receive data from or to each other via Ethernet. Network equipment test instrument is designed and developed in order to locate the failed equipment or link. 32 bit ARM processor is selected while the uCOS-Ⅱ embedded operating system introduced, thus to meet the multi-tasking real-time requirements. And the monitoring mission is designed for real-time system supervising, thus the system reliability and stability can be fairly solved.
