摘要
自动气象站作为一种自动观测和存储气象观测数据的设备,弥补了空间区域上气象探测数据空白。风向是气象站所测量的重要气象要素之一,对气象和相关领域的发展都有着及其重要的意义。如今风向传感器大多采用的是光电风向传感器,其使用的格雷码盘输出为离散的数字信号,测量精度不高。设计了一种满角度电位器及风向检测算法,研制了一套基于STM32的风向检测装置,并在LCD上显示。实验测试表明,该系统能较好地实现对风向的检测,测量精度明显提高。
As an equipment for automatic observation and storage of meteorological observation data, the automatic meteorological station makes up the gap of meteorological detection data in spatial areas. Wind direction is one of the important meteorological elements measured by meteorological stations, which is of great significance to the development of meteorology and related fields. Nowadays, most wind direction sensors use photoelectric wind direction sensors, which use the Gray code disk output for the discrete digital signal, and the measurement accuracy is not high. In this paper, a full-angle potentiometer and wind direction detection algorithm was designed, and a set of wind direction detection device based on STM32 was developed and displayed on the LCD. Experimental test shows that the system can detect the wind direction well, and that the measurement accuracy is significantly improved.
