国家地震烈度速报与预警工程定制软件总体设计

国家地震烈度速报与预警工程现已建设世界上规模最大的、总数超过15000个台站的地震烈度速报与预警观测站网。定制软件是预警工程的核心内容之一,将实现我国地震观测领域数据处理系统的全面升级。本文结合定制软件项目建设目标、业务功能需求等情况,从设计思路、总体架构、分系统功能、部署方式、性能指标和关键技术指标等方面对定制软件总体设计进行介绍。定制软件的总体设计契合预警业务功能需求,使得预警工程具备高稳定性、低延时、高可靠度、高处理性能的数据处理、紧急地震信息服务、数据综合服务和技术支持与保障能力,使地震预警和烈度速报两大功能得到落实,使工程项目的防震减灾效能得到切实体现。

Overall Design of Customized Software for the National Seismic About the National Seismic Intensity Rapid Reporting and Early Warning Project

The National Seismic Intensity Rapid Reporting and Early Warning project of China has built largest earthquake intensity rapid reporting and early warning observation station network in the world. With a total of over 15,000 stations,it is about to be put into full testing operation. Customized software is one of the core components of the early warning project,which will realize a comprehensive upgrade of China''s earthquake observation data processing system. In this paper,the overall design of customized software is introduced from the aspects of design ideas,overall architecture,subsystem functions,deployment methods,performance indicators and key technical indicators. Such design with high efficient performance of data processing,emergency earthquake information providing,meets the functional requirements of the early warning,so that the early warning project has high stability and reliability,low latency,comprehensive data service capabilities and technical support capabilities. As the results,the two major functions of both earthquake early warning and intensity quick report are implemented,which makes the earthquake prevention and disaster reduction more efficient.
