基于微服务架构的分布式灾情管理系统设计

Design of Distributed Disaster Management System Based on Micro-service Architecture

为及时获取多源异构灾情信息,以多源灾情管理系统的架构和功能模块为研究对象,针对单体系统存在灵活性差、性能低、资源消耗不均衡等问题,提出基于微服务架构设计,在分布式环境下利用SpringCloud框架,通过业务划分,设计独立模块的微服务,同时加入熔断器、消息队列等组件,缓存处理数据。运用地理信息系统实现灾情数据实时获取、灾情编码入库、地震灾情速报产品实时发布以及灾后应急管理。实验结果表明,采用多层微服务架构,系统扩展性增强,并发性能得到提高,提升了灾情数据管理效率。

Taking the architecture and functional modules of the multi-source disaster management system as the research object,in this paper,we proposed the micro-service-based architecture design to obtain the multi-source heterogeneous disaster situation in a timely manner,in order to solve the problems of the poor flexibility,low performance,unbalanced resource consumption existing in the single system. In the distributed environment,the Spring Cloud framework is used to design micro-services of independent modules through business division. At the same time,components such as fuse and message queue are added to cache and process data. The geographical information system is used to achieve the real-time acquisition of disaster data,disaster coding into the database,real-time release of earthquake disaster quick report products and the post-disaster emergency management. Our results show that when the multi-layer micro-service architecture is adopted,the system scalability is enhanced,the concurrent performance is improved,and the disaster data management efficiency is increased.
