摘　　要：针对某任务计算机系统中多个单板计算机与多串口板之间不能通过背板总线直接进行读、写访问的问题,文中提出了以多串口板为透明桥梁,通过网络数据包实现多个单板计算机与外部设备之间双向数据交互的监控软件解决方案.监控软件充分利用了实时嵌入式操作系统VxWorks的微内核、多任务、组件可裁减特性和消息队列机制解决了同时监听8路外设、实时、大量数据交互等难点问题,实现了一个代码尺寸小、实时性高、处理能力强的监控单元.实验表明:该软件达到了多任务计算机系统的设计初衷,有效完成了网络与多串口之间的透明互通.The terminal display control computer unit of some system had a problem that its single CPU unit cannot access the multi-channel UART board （MCUB） directly through the compact PCI bus. To settle it,the paper presents a monitoring software solution,which takes the MCUB as a transparent bridge,exchanges bidirectional data between the CPU unit and the external devices via network packets. By fully applying the characters of the real-time embedded operating system VxWorks,e.g. micro kernel,multi-task,scalable components and message queue,the software tackles such difficulty as listening eight external devices simultaneously,real time and mass data exchange,realizes a mini-sized,highly real-timed and well processed monitoring system. Experiment shows that the monitoring software satisfies the requirements of system development.
