摘　　要：结合嵌入式实时操作系统VxWorks实现视频监控系统的实际应用，以其中的串行通信为例，讨论了在VxWorks下实现设备操作和数据通信的关键技术和相应的机制，给出了软件流程和程序示的。所讨论的通信机制可以推广到串行设备以外的其它通信设备。Combining with the application of video supervision system implemented with embedded real-hme operating system VxWorks,with the serial communication in it as an example, the key techniques and corresponding mechanism about realization of device operating and data communication in VxWorks are discussed. Software diagram and corresponding program examples are provided. The communication mechanism discussed here can expand to other communication devices beside serial device in VxWorks.
