摘　　要：针对区域环境的温度精确监控要求,利用ZigBee无线传感器网络技术,提出了一种基于自适应模糊逻辑的虚拟传感器温度计算方法;利用该算法根据参考点的相关数据,对传感器采集的温度信息进行计算,得到监控点的虚拟温度信息,增加了温度监控系统的鲁棒性;实验结果表明:相对于标准Mandani和均值模糊逻辑算法,基于自适应模糊逻辑的温度计算方法能够获得更为准确的信息,提高了粮仓温度监控的准确性与可靠性。Aiming at the precise requirements of regional environmental monitoring, a calculation method of temperature which based on virtual sensor by adaptive fuzzy logic was proposed, which utilizes wireless sensor network technology of ZigBee. This method of calculating temperature information collected by the sensors, increases the monitor system＇s robustness by adaptive weighting algorithm. The experi- mental results show that temperature calculation method based on adaptive fuzzy logic can obtain more accurate information than standard Mandani fuzzy logic method and average fuzzy logical algorithm, and improve the accuracy and reliability of the temperature monitoring.
