摘　　要：在分析了嵌入式W eb服务器设计思想的基础上,根据瘦HTTP服务器的设计思想,研究了传统无纸记录仪的Internet扩展设计,详细分析了网络无纸记录仪的具体功能要求,进而确定了网络无纸记录仪的设计框架。将网络无纸记录仪系统分为两个模块;服务器部分由以太网接口模块、TCP/IP协议栈模块、HTTP服务器及嵌入式文件系统模块构成;客户端部分通过ActiveX技术设计了一个虚拟仪表,实现了Internet扩展。根据这种实现方法,提取了一种通用的仪表Internet扩展方案。According to the design concept of thin HTI＇P server, based on analysis of design for embedded Web server, the traditional Internet extension for paperless recorder is studied. The concrete functional demands of the network paperless recorder were analyzed in detail, and then its design frame was confirmed. The network paperless recorder system was divided into two parts：the server was made up of Ethernet interface module, TCP/IP protocol stack module, HTrP server module and embedded file system module; the client, a virtual instrument, was designed by ActiveX technique to fulfill the internet extension. According to the implementing method, a generalized lntemet extension strategy for instruments is proposed.
