无线传感器网络在加密气象观测中的试用研究

Research on Wireless Sensor Networks in Intensive Weather Observation

无线传感器网络在武汉市气象局开展加密观测试用研究。在对比观测中发现无线传感器节点采集的气温总体比气象观测标准温度偏高;在晴天太阳辐射相对较大的情况下,随着太阳辐射量的增加,误差加大。然而,基于无线传感器网络的加密气象观测系统能够提高气象观测的时空密度,能够降低数据采集和传输的复杂性,在城市防灾减灾和大型社会活动的气象保障服务中,具有一定的服务优势。

Trial study conducted intensive observations of wireless sensor networks in Wuhan Meteorological Bureau. In the comparative observation, it is found that the temperature collected by the wireless sensor nodes is generally higher than the standard temperature of meteorological observation. When the solar radiation is relatively large on a sunny day, the error increases as the solar radiation increases. However, the meteorological observation system Based on wireless sensor network can improve the space-time density of meteorological observation and reduce the complexity of data collection and transmission. It has certain service advantages in meteorological support services of urban disaster prevention and mitigation and large-scale social activities.
