压电式雨量传感器的自适应标定方法
|
摘要
由于压电式雨量传感器安装使用前一般需要进行准确标定,文中以同步采集的翻斗雨量计输出信号为参考雨量,利用基于模型的自适应训练和优化方法,从而实现在模拟降雨或实际降雨中实现传感器输出关系的标定,实现雨滴粒径以及降雨量的测量。试验结果表明,该方法能替代传统的直接标定方法,简化标定实验的硬件需求,为在气象站及野外环境的降雨检测的应用提供参考价值。
Because the piezoelectric rain sensor needs to be calibrated accurately before it is installed and used,the output signal of the dump rain gauge collected synchronously is taken as the reference rainfall,and the adaptive training and optimization method based on the model is used to realize the calibration of the output relationship of the sensor in simulated or actual rainfall,and to realize the measurement of the diameter of raindrops and rainfall.The experimental results show that this method can replace the traditional direct calibration method,simplify the hardware requirements of calibration experiments,and provide reference value for the application of rainfall detection in meteorological stations and field environments.
