【摘要】 本文介绍了测量技术与仪器网络化的现状及其发展趋势，探讨了基于局域网的仪器网络的定义、优点及其发展情况。目前，基于局域网的仪器网络的发展正处于起步阶段，可像计算机一样直接连入局域网的网络化仪器初见端倪。能将大多数非网络化仪器接入局域网的接口服务器品种少，价格昂贵，极大的阻碍了仪器网络的发展。为了满足市场的需求，推动基于局域网的仪器网络的发展，本文在参阅了国内外文献资料，分析了各种仪器网络组建方案和接口服务器的设计方案后，阐述了自己对基于局域网的仪器网络的理解，详尽的论述了接口服务器的软硬件设计和网络通信协议的实现。本文是在开发具有串行接口和并行接口的多功能接口服务器的实践基础上写就的。该接口服务器具有多接口、性能可靠、成本低的优点，能把具有EPP并行接口的仪器接入局域网，也是本接口服务器特有的新功能。作者希望通过新型接口服务器的研制，为基于局域网的仪器网络的发展作一点努力。更多还原

【Abstract】 This paper introduces the present state and development trend of measure technology and instrument, discusses the definition, advantage and development status of instruments network based on the local network. At present, it is in the beginning stage of development of instruments network based on the local network. There are a few network-instrument that can directly connect into network like a computer. Interface server that can connect most common instruments into network is lacking and costs highly. So the development of equipments network is slow down. In order to accelerate the development of instruments network, we must develop more interface servers that have all kinds of interface, such as RS232 serial port, EPP parallel port etc. Based on reading internal and external reference literature and analyzing deferent design scheme, this thesis descript author’s understanding of instruments network, expatiate the hardware and software design of interface server and the realization of network communication protocols. The author hopes to contribute to the development of equipments network through developing the multi-function interface server.更多还原
