一种基于微服务架构的突发事件预警辅助决策系统的设计与实现

单体式架构应用在突发事件预警辅助决策系统开发中不能满足现实需求，本文引入了微服务架构设计开发该辅助决策系统.通过分析微服务架构在复杂系统中相对于传统单体式架构的应用优势，设计出一种基于微服务架构的突发事件预警信息发布辅助决策系统，该系统选用Spring Cloud微服务框架，并对其进行适当的扩展，创建了基于该系统设计的注册中心与网关.系统采用二三维一体化地理信息系统作为展示平台，通过接入各行业静态、危险源动态监测数据，根据设定的模型进行数据融合、处理，辅助进行预警信息生成、发布及应急处置阶段的指挥决策.所设计方案在湖北省突发事件预警发布辅助决策系统中得以实际应用，验证了该类系统使用微服务架构的合理性和有效性.

Design method of early warning assistant decision system for microservice architecture

A single architecture cannot meet the demand for the development of an emergency early warning auxiliary decision system.In order to solve this problem,a microservice architecture is introduced to design and develop the system.By analyzing the advantages of applying a microservice architecture in a complex systeminstead of a traditional monomer-type structure,we designed a microservice architecture based on the emergency early warning information release auxiliary decision system.This system selects the Spring Cloud service framework,and makes an appropriate extension on itto create the registry and gateway based on the system design.The system adopts a 2D and 3D integrated geographic information system as the display platform.By accessing the static monitoring data and hazard source dymamic monitoring data on various industries,the system can integrate and processes data according to the set mode,and assists in command and decision-making in the early warning information generation,release,and emergency response stages.This design scheme has been applied tothe Hubei province emergency early warning and release aided decision system.The rationality and effectiveness of this kind of system,which uses a microservice architecture,has been verified.
