摘要
针对传统车载移动气象台在复杂地形中灵活性差和覆盖面积小的缺点,提出了一种基于无线传感器网络的应急气象观测系统。系统包括数据采集层和远程数据传输层,数据采集层实现了一种基于无线传感器网络的便携式气象观测节点,远程数据传输层实现了一种具有通用分组无线业务(GPRS)和北斗卫星通信模块的车载网关。测试结果表明:系统在应急气象观测中便于部署,可以有效扩大气象观测网络的覆盖面积,提高气象观测密度和精度,保证气象观测数据的稳定传输。
Aiming at defects of poor flexibility and small coverage area of traditional vehicular meteorological station in complex terrain, a kind of emergency meteorological observation system based on wireless sensor networks（WSNs） is presented. The system includes data acquisition layer and remote data transmission layer,a portable meteorological observation node based on WSNs is achieved in data acquisition layer and a vehicular gateway with GPRS and the Beidou satellite communications modules in remote data transmission layer. Test result shows that the system is easy to deploy in emergency meteorological observations can effectrively broaden coverage area, increase density and precision and assure stable data transmission.
