【摘要】 近年来我们国家大力发展专用网络来加强对远程会诊的支持。目前大多数现有的远程会诊平台是基于IPv4网络点对点或集中式系统,网络条件不良往往会导致通信质量下降,服务中断,整个系统陷于瘫痪。各个远程医学中心的平台之间大量使用IPv4网络保留的内部地址缺乏交互,无法合作和资源共享,不仅妨碍了远程医学的发展,同时也由于重复建设导致了资源的浪费。以往的会诊合作在同一个远程医学中心安排下进行,一般采用人工安排的方式,工作效率较低。随着Internet的广泛应用,以及IPv6网络的相关研究的进行,网络带宽的逐渐加大和网络技术的迅速发展,针对现有远程医学会诊平台在现有IPv4网络上运行时遇到一些问题,更促进了研究基于IPv6网络的分布式远程会诊平台来解决医疗机构组成动态联盟时所面临的资源共享和协同工作等问题。文章研究了新一代的Internet协议IPv6协议和传统的IPv4协议相比较所具有的新特点和分布式架构的优势,以及在远程医学中起到的作用。文章讨论了通过会诊事件表达合作医疗机构之间的会诊需求,在各医院信息系统之间搭建了语义互通的桥梁;同时将基于主题和内容的事件发布/订阅机制引入,解决了合作伙伴的查找问题。文章分析了基于IPv6的分布式远程会诊平台的建立过程中所存在的许多关键问题,包括从现有系统移植、数据描述、资源整合、安全保证、用户验证等。文章还详细阐述了原型系统面向服务的远程会诊系统的设计、开发和测试的过程,分析了主要的技术细节。最后,文章在总结研究结果的基础上,分析了还有待解决的问题,为进一步完善该平台的各种功能奠定了基础。更多还原

【Abstract】 In recent years there have been many international telemedicine projects and programmes. Many countries vigorously develop the private network to strengthen the support for teleconsultation. At the present time, the architecture of most teleconsultation platforms is centralized. Poor network condition often leads to low quality of communication, and failure of data center causes all service to terminate. The service scope of each telemedicine center is limited and the cooperation between them is little, which prohibited the development of telemedicine and also resulted in redundant construction. The former consultation cooperation is usually assigned by telemedicine center with manual interference, which decreases the efficiency a lot. The lack of integration between teleconsultation platform and hospital information system (HIS) leads to useless work as well.With the extensive application of Internet, as well as IPv6 network-related research, the network bandwidth and the gradual increase in the rapid development of network technology, but also promote the study of distributed network based on IPv6 teleconsultation platform has become an important trend. Facing the problems of existing telemedicine remote consultation platform, IPv6 is proposed based on the distributed platform for teleconsultation and design, in order to solve the resource-sharing and cooperative-working related problems which medical institutions will meet during the buildup of dynamic alliance. This paper makes a research on the new features of IPv6 network and advantages of distributed architecture, and puts forward a notion of IPv6 based distributed telemedicine remote consultation platform.The paper analyzes many key problems existing in the process of establishing IPv6 based distributed telemedicine remote consultation platform, such as migrating from existing systems, data description, resource integration, security, user authentication, etc. In addition, the technical details in the design, development and test processes service-oriented teleconsultation platform, a prototype project of the platform, have also been introduced.At last, on the base of the conclusion of our research, some problems which should be solved in our future work are pointed out and discussed.更多还原
