摘要
介绍了一种基于LoRa协议的风数据采集方法,改进的CFD计算模型进行数值预测,交叉验证得到每组数据的实际值和预测值,均方根误差、相关系数和显著性检验对结果进行分析。结果表明背风坡预测误差大,迎风坡和侧风坡风速误差0. 5m/s左右,风向误差30。左右。
In this paper, a wind data acquisition method based on LoRa protocol is introduced. The improved CFD calculation model is used for numerical prediction. The actual and predicted values of each group of data are obtained through cross validation. Results showed that the leeward slope prediction error is large, and the windward side of side slope error about 0. 5 m/s wind speed wind,the wind error about 30 °.
