摘　　要：在自动化控制及其他民用设备、工业控制如电力设备系统等领域,众多设备的对外通信接口仍然是低速串口。但低速串口有其固有的缺点:无法集中、全面、准确而实时地监控数据。介绍基于微处理器SEP3203串行通信转网络通信数据模块的硬件设计,同时介绍以嵌入式操作系统Nuc leus为平台设计的串口通信、以太网通信和USB接口通信的设计方法。In automatization control and other civilian equipment as well as industrial control field such as electric device system,many devices are still use low-speed serial interface as external communication interface.But there are inherent drawbacks in low-speed serial interface,it is unable to monitor data concentratively,comprehensively,accurately and real-timely.This paper introduces the hardware design of data modules transferring serial communication to network communication based on microprocessor SEP3203.At the same time,the design method of serial communication,network communication and USB interface communication based on embedded operating system Nucleus are introduced as well.
