【摘要】：公共卫生应急处理部门通过对突发事件、应急保障资源等信息的掌握来制定决策方案,通过对卫生应急资源的精确定位来保障高效的资源调用和决策实施。然而,目前各卫生机构间条块分割,应急资源缺乏有效的整合,存在大量的信息孤岛。因此,如何实现卫生应急资源的数据共享成为了公共卫生应急处理工作必须解决的问题。围绕这一目标,本文首先对卫生应急数据的组织形式和流转特点进行了研究,建立了各级卫生机构之间的应急数据组织结构关系。在此基础上,利用GIS技术和网络通信技术,提出了一种卫生应急数据交换中间件模型,来实现多级卫生机构间的高效、安全数据交换和共享。在模型的实现过程中,本文攻克了以下三点关键技术： 1)通过对XML与数据库双向映射方法的研究,采用基于模型的数据转换方法来实现异构数据源的数据转换； 2)利用基于消息队列模式的中间件技术,通过屏蔽数据交换环境的差异来完成复杂网络中的数据异步、安全通信,从而建立了不同数据库之间的有机联系； 3)提出了一种基于规则的标志词分割匹配算法,利用边分词边匹配的方法来提高地址匹配效率,实现了业务数据和空间地理数据的有序组织,为应急资源的可视化管理提供数据支持。结合浙江省卫生应急处理决策系统,本文对以上提出的数据交换中间件模型进行了应用验证。实践表明,该模型以统一的数据定义与编码、统一的数据转换标准为原则,通过建立各级卫生机构之间的数据交换机制,保障了应急资源的高效调用,提高了应急决策的效率,为实现公共卫生信息化建设的数据共享提供了一种可行性方案。
[Abstract]:The public health emergency management department formulates the decision plan by mastering the information such as emergency events, emergency support resources and so on, and ensures the efficient resource transfer and decision implementation through the accurate positioning of the health emergency resources. However, At present, there are many isolated information islands due to the lack of effective integration of emergency resources among health institutions. Therefore, how to realize the data sharing of health emergency resources has become a problem that must be solved in public health emergency management. Focusing on this goal, this paper first studies the organizational form and flow characteristics of health emergency data, and establishes the organizational structure relationship of emergency data among health institutions at all levels. On this basis, using GIS technology and network communication technology, A middleware model of health emergency data exchange is proposed to realize efficient, secure data exchange and sharing among multi-level health institutions. In the process of implementing the model, the following three key technologies are solved:. 1) based on the research of bidirectional mapping method between XML and database, the data conversion method based on model is adopted to realize the data conversion of heterogeneous data sources; 2) by using the middleware technology based on message queue mode, the asynchronous and secure communication of data in complex network is accomplished by shielding the difference of data exchange environment, and the organic relation between different databases is established. 3) A rule-based segmentation and matching algorithm is proposed to improve the efficiency of address matching and realize the orderly organization of business data and spatial geographic data. Provide data support for visual management of emergency resources. Combined with the health emergency decision system of Zhejiang Province, this paper verifies the above data exchange middleware model. The practice shows that the model is based on the unified data definition and coding, and the unified data conversion standard. By establishing the data exchange mechanism among health institutions at all levels, the efficient transfer of emergency resources is ensured, the efficiency of emergency decision is improved, and a feasible scheme is provided for the realization of data sharing in the construction of public health information system.
