摘要
在农业生产、气象与环境等领域,测量太阳辐射有着很强的现实意义。主要介绍了一种面向野外环境下太阳辐射测量仪的信号处理方法。该辐射测量仪使用太阳能供电和无线通讯的方式以解决野外环境下无市电、上下位机通讯距离远的问题。信号处理过程主要包括对传感器的输出信号进行信号调制、对信号进行放大、带通滤波滤除噪声以及信号解调。最后使用辐射测量仪进行试验,通过测量数据证明了该信号处理方式的合理性。
It is of great practical significance to measure solar radiation in agricultural production, meteorology, and the environment. This paper mainly introduces a signal processing method of solar radiation measuring instrument suitable for the field environment. The radiation measuring instrument uses solar power to solve the problem of no mains electricity in the field environment and uses wireless communication to solve the problem of long communication distance between the upper and lower computers. Signal processing mainly includes signal modulation, signal amplification, bandpass filtering,and signal demodulation. Finally, the radiation measuring instrument is used to test the signal processing method, and the rationality of the signal processing method is proved by the measured data.
