基于NB-IoT通信技术的水文遥测系统设计

Design of Hydrological Telemetry System Based on NB-IoT Communication Technology

随着社会进步和信息技术的发展,为了提升城市防汛防旱防风快速应急响应能力,采用低功耗物联网NB-IoT通信技术,以产品集成代替传统系统集成的方式设计水雨情遥测终端,进一步降低设备对外部环境的依赖性,提高水文遥测系统前端数据采集的稳定性与可靠性,让大规模部署水文遥测终端进行监测成为了可能。广州市南沙区三防办根据城市应急防控需求,建设了一套成本低、扩展性强、可靠性高的新一代水文遥测系统,快速覆盖城市易涝风险点,掌控南沙区城市关键位置的水雨情数据实时变化情况,辅助三防应急决策,提高应急响应能力,实现防汛力量的精准布防,降低城市居民财产损失。结果表明,基于NB-IoT通信技术的水文遥测系统首次在广州市范围内大规模应用,能为应对汛期发生的各种灾害提供了高效数据支撑。

With the progress in society and information technology,the rapid emergency response capability for urban flood,drought,and wind prevention needs to be improved.Given the demand,this paper adopts the low-power Internet of Things(NB-IoT)communication technology to design water and rain telemetry terminals in the way of product integration instead of traditional system integration.This technology further reduces the dependence of the equipment on the external environment and improves the stability and reliability of the front-end data acquisition of the hydrological telemetry system,making it possible to deploy the hydrological telemetry terminal for monitoring on a large scale.According to urban emergency prevention and control requirements,Guangzhou Nansha District Flood and Drought Prevention Headquarters Office constructed a new generation of hydrological telemetry system with low cost,strong scalability,and high reliability.By quickly covering urban flood risk points,the system can master real-time water and rain data in the key position of Nansha District to assist the emergency decision,improve emergency response capabilities,and realize the precise distribution of flood control forces,thus reducing the property losses for urban residents.The results show that the hydrological telemetry system based on NB-IoT communication technology applied on a large scale for the first time in Guangzhou can provide efficient data support for dealing with various disasters in flood seasons.
