| 摘要: |
| 地震烈度速报与预警系统主要包含台站观测系统、数据处理系统、紧急地震信息服务系统、网络通讯系统、技术保障系统五大模块。基于四川地震预警台网实际情况,规划设计了紧急信息服务系统中发布系统的架构。本文对系统中运用的MQTT协议、HAProxy开源软件、Dubbo框架等技术进行了介绍,并以2022年芦山6.1级等地震的预警信息发布情况为例,阐述该系统在实现地震预警中的优势与作用。 |

| Abstract: |
| The earthquake intensity rapid reporting and early warning system consists of five key modules:the station observation system,data processing system,emergency earthquake information service system,network communication system,and technical support system. This study focuses on planning and designing the architecture of the publishing system within the emergency information service module. It also introduces the MQTT protocol and Haproxy open-source software as core components. To demonstrate the system's effectiveness,this paper uses the release of early warning information during recent earthquakes in Lushan as a case study. The analysis highlights the system's advantages and functionality in delivering timely and reliable earthquake early warnings. |
