摘　　要：为了向社会公众提供可靠、高效的紧急地震信息,基于地震预警信息发布业务需求,提出了紧急地震信息发布系统的4层技术架构方案,包括数据接入层、核心业务层、中间件层和应用服务层,对MQTT协议、数据加密、信息验证等技术进行了研究,制定了基于MQTT的紧急地震信息发布协议,通过数据加密和Token验证机制保证数据传输过程中的安全性、稳定性,实现了高效的信息发布服务。通过对京津冀、川滇、新疆、甘肃等地区达到发布条件的86个预警事件信息的发布时间、接收时间、应答时间等进行对比分析,得出平均发布时效为570 ms,表明基于MQTT协议的紧急地震信息发布系统的发布协议和技术架构是可行性的。In order to provide reliable and efficient emergent earthquake information to the public,this article proposes a four-layer technical architecture scheme based on the business requirements of the earthquake warning information release,including data access layer,core business layer,middleware layer,and application service layer.The MQTT protocol,data encryption,information verification and other technologies are studied,and an MQTT based information release protocol is developed to ensure the security and stability of data transmission through data encryption and Token verification mechanisms,achieving efficient information release services.By analyzing the timeliness and reliability of warning events,the feasibility of the release protocol and the technical architecture studied in this paper has been verified.The results provide technical solutions for the national intensity rapid reporting and the early warning engineering information release,and have been applied into this information release system which provides the earthquake early warning information services for governments at all levels,schools and the public.Through comparative analysis of the information release time,the reception time and the response time,etc.of 86 emergent earthquake events in Beijing-Tianjin-Hebei region,Sichuan-Yunnan region,Xinjiang and Gansu,we obtain the average release time is about 570 ms,indicating the feasibility of the release protocol and the technical architecture studied in this paper.
