摘　　要：针对串口通信的局限性,为满足串口通信设备快速灵活接入TCP/IP网络需求,提出了一种基于CPCI总线的串口服务器模块的设计方案。给出了串口服务器模块的系统体系结构,并对硬件结构、板载嵌入式软件和客户端软件3方面做了详细介绍,最后比较了串口服务器模块与传统串口服务器的区别,分析了其主要应用模式。实现了RS232/422串口与TCP/IP网络之间数据的双向透明传输、远程配置管理和数据共享的功能。Aiming at the limitation of serial communication, in order to meet the requirements of serial communication equipment accessing to TCP/IP network quickly and flexibly, a design scheme of serial server module based on CPCI bus is proposed. The system architecture of serial server module is given, and the hardware structure, the onboard embedded software and the client software are introduced in detail. Finally, the difference between serial server module and traditional serial server is compared, and the main application mode is analyzed. The functions such as bidirectional transparent transmission between RS232/422 serial port and TCP/IP network, remote configuration management and data sharing are implemented.
