- 自动气象站在气象领域应用广泛,对其提供的气象数据精度要求越来越高。风作为重要的气象要素蕴含巨大的自然力量,是自动气象站检测的重要要素之一,对风速的高精度检测至关重要。如今,自动气象站对风速的检测常使用光电式传感器,其检测精度不够高。因此提出一种全角度无限旋转单电位器,并设计一种高精度风速检测算法,通过电位器单位时间的角度变化,计算三杯式风速传感器角速度,再计算出风速,提高检测精度。以全角度电位器为核心,基于STM32设计一套风速检测装置,经测试该装置能够高精度检测风速,并通过蓝牙通信在手机端显示。
- Abstract:
- Automatic weather stations are widely used in the meteorology field, and the requirements for the accuracy of the meteorological data are getting higher and higher. Wind, as an essential meteorological element which contains a huge natural energy, is one of the important elements for automatic weather station detection. It is very vital for high-precision detection of wind speed. Nowadays, automatic weather stations often use photoelectric sensors to detect wind speed, and their detection accuracy is not high enough. This paper proposes a full-angle infinitely rotating single potentiometer, and designs a high-precision wind speed detection algorithm. Through the angle change of the potentiometer per unit time, the angular velocity of the three-cup wind speed sensor is calculated, then the wind speed is calculated, which improves the detection performanceprecision. This paper takes the full-angle potentiometer as the core and designs a set of wind speed detection devices based on STM32. The test results manifest that the device can detect the wind speed with high precision and display it on the mobile phone through Bluetooth communication.
