| 摘要: |
| 为增强地震专题图发布的时效性，提升地震专题图服务能力，设计了一套基于MQTT协议的地震专题图自动生成和推送系统。该系统通过移动互联网与地震速报系统之间保持长连接，利用MQTT协议实时接收地震速报信息，根据地震烈度衰减模型生成地震影响场，然后运用ArcPy站点包进行相关空间分析和自动出图，最后利用企业微信的开发接口，实现了地震专题图的快速发布。地震专题图自动生成和推送系统已向福建省地震局和各地级市地震局相关人员提供服务，并在数次中国台湾的地震中取得良好效果。 |

| Abstract: |
| In order to enhance the timeliness of the release of earthquake thematic maps and to improve the service capability, in this paper we design a set of automatic generation and push system for earthquake thematic maps based on the MQTT protocol. The system maintains a long connection with the earthquake quick report system through the mobile Internet, uses the MQTT protocol to receive the earthquake quick report information in real time, generates the earthquake influence field according to the seismic intensity attenuation model, and then uses the ArcPy site package to perform related spatial analysis and automatic map output. Finally by using the development interface of enterprise WeChat, the rapid release of earthquake thematic maps was realized. The automatic earthquake thematic map generation and push system has provided services to relevant personnel of the Earthquake Administration of Fujian Province and the earthquake administrations of various cities, and has achieved good results in dealing with several earthquakes in Taiwan. |
