【摘要】 NC(Network Computer),是网络计算机的简称,也称之为网络终端机,是一种完全依赖于现代网络的终端设备~[1]。近年来,我国在信息技术领域有很大的进步,已经成功开发了“方舟”、“龙芯”系列及北大众志等通用CPU和基于开放源代码的国产Linux操作系统,如中软Linux、红旗Linux等。这些技术的不断发展和成熟为我国在信息化过程中摆脱对国外软硬件产品的依赖创造了可能。因而我国上下开始逐步重视利用了自主知识产权技术的网络计算机NC研发和应用。 本文依据国家863计划项目《网络终端机(NC)在企业信息化工程中的应用研究》子课题《NC在医院信息系统中的应用研究》的任务要求,在分析和研究现有各医院信息系统的基础上,提出了NC在医院信息系统中应用的总体设计方案,并选取了医生查房系统作为NC应用示范的重点,设计了基于802.11b无线局域网的查房系统。查房系统软件采用B/S模式来实现。服务器端软件主要采用JSP技术、Web数据库技术及相关的网络编程技术来完成;该软件运行于接入服务器上,并与原有的医院信息系统融为一个整体,成为其中的一个子系统,不仅不影响医院原有HIS功能,而且成为医院HIS与PACS相互沟通的桥梁,提高了医院各种资源的兼容性。浏览器端(Browser)采用移动式NC,用无线接入的方式访问接入服务器的资源,它需要自带Web浏览器、具有中文输入功能并支持802.1lb无线局域网协议。 本文着重探讨实现查房系统的软件实现,及其在嵌入式Linux环境下实现无线接入。在本项目研究过程中,作为项目组成员作者参与了NC在其它领域的应用研究和推广工作,首次提出了NC在农村社会经济调查信息系统中的应用推广方案,及反拍卖系统中具有嵌入安全识别NC的应用。更多还原

【Abstract】 NC(Network Computer) is a terminal fully based on network, generally, including Thin Clients and Information Appliance, etc. Recent years, our country has succeeded in developing native common CPU, such as Ark series, GodSon series, and Unity-863 CPU, and domestic Linux Operation Systems based on open source code, such as ChinaSoft Linux, and Redflag Linux, etc. Those techniques make it possible for us to produce our native NC products.According to the requests of the project Research on Network Computer Applied in Hospital Information System, which is the subproject of China 863 Planning Project Research on Network Computer Applied in Enterprise Information Engineering, and based on the analysis of some general Hospital Information Systems, this article proposed the NC applied solution in Hospital Information System. Furthermore, author selected the Hospital Ward Information System as a demonstrated point, and designed a new NC applied system, which worked in Browser/Server mode. The system software is realized mainly by JSP technique, Web Database technique, and some other related network programming techniques, and circulates on a Server. The Server worked as a sub system of HIS. It do not affect the original function of HIS, whereas, it could connect the HIS and PACS. The Browser is a mobile NC, which could connect the Server by the way of wireless. It also should have embedded Web browser and simplified Chinese input function.This article will mainly discuss the key techniques about system software and wireless connection under embedded Linux Operation System. During the research, author, as a team member, actively participated in the work to apply NC in other information fields, and proposed firstly NC applied solution in Country Society Economy Investigating Information System. Author also presented a new NC pattern with embedded security module applied in the Reverse Auction Technology.更多还原
