Abstract: Earthquake Prevention and Reduction Information System (EPRIS) includes Seismometry Sub-System,Strong Motion Sub-System,and Active Fault Sub-System and so on. These sub-systems are independent,hetero-structured and cross networked. They are based on different platforms and developed by different programming languages. There is lack of commutation and collaboration among them. At present,CEA plans to build a self-contained Chinese Digital Seismic Networks System in which new operations and new platforms are brought forward. How to protect the existing investment and realize integration between the old systems and new systems is a pending question. In view of independence,hetero-structure and cross-network of EPRIS,a Webservice-based integration model is proposed for EPRIS and a case study is performed in the paper. The Web Services technology is independent of programming language and all kinds of platforms,so it can solve the above-mentioned problem.

摘要： 防震减灾信息系统包括测震、强震、活断层等子系统,这些系统之间是独立、异构和跨网络的。目前,地震行业需要构建一个完备的中国数字地震观测网络体系架构。如何实现原有系统之间的集成,如何在保护现有投资的前提下,把原有系统和新的防震减灾信息系统集成起来是一个亟待解决的问题。考虑到防震减灾信息系统的特点,文中提出了一个基于Web Services的防震减灾信息系统的集成模型,并对一个实例进行了研究。该模型解决了防震减灾信息系统集成中遇到的2个难题,首先是客户端和服务器端的通信问题,其次是防震减灾信息系统之间的互操作性问题。通过研究实例对该模型进行了一定程度上的验证,结果表明该模型对将来面向整个地震行业的防震减灾信息系统的集成具有深远的意义和良好的发展前景。
