摘　　要：许多通信设备如通控机、数话同传机、电台等通过串口进行数据转发,各通信设备室之间通过无线或有线方式通信,通信的中断需要及时找出故障的原因,设计开发串口设备测试仪对出现问题的通信设备或链路进行定位。引入嵌入式操作系统μC/OS-Ⅱ,满足多个串口数据采集的实时性要求,利用CAN总线传输距离远的特点完成数据的汇总与转发,并设计监视任务实时监控系统的运行,使系统可靠性和稳定性得到了较好的解决。Communications equipment such as military-controlled machines transmits the data through serial port. There are interactive data between different equipment rooms, so the communications interruption need for identifying the reasons timely. The paper designs the serial test instrument for problems detecting. The embedded operation system μC/OS-Ⅱ is introduced for catering to the requirement of real-time serial data collection, and it chooses CAN-bus for data-sum and transmit. It also designs monitoring mission for real-time system supervising, so the reliability and stability of system can be better solved.
