【摘要】：风速仪是测量风速的重要仪器。针对目前常见风速仪存在的体积大、不方便携带、在恶劣环境下感应元件易损坏等问题。设计了基于热敏电阻的无线风速仪。该风速仪以STC12C5620AD单片机和E32-TTL-100无线数据传输模块为核心,使用了敏感的热式风速传感器FS5,克服了以往热式风速仪探头的"脆弱"和不易清理的缺点,同时具有量程大,灵敏度高,使用温度区间大,续航时间长的优点。经小型低速风洞标定,采用最小二乘法拟合,所得方程符合指数分布,复回归系数为0.996和0.997,可满足实际使用的需求。
[Abstract]:Anemometer is an important instrument for measuring wind speed. The wireless anemometer based on thermistor is designed, which is transmitted by STC12C5620AD microcontroller and E32-TTL-100 wireless data. Input module is the core. The sensitive thermal wind speed sensor FS5 is used, which overcomes the weakness of the former thermal anemometer probe and is not easy to clean. At the same time, it has the advantages of large measuring range, high sensitivity and large temperature range. After the calibration of the small low speed wind tunnel and the least square method, the obtained equation accords with the exponential distribution, and the complex regression coefficients are 0.996 and 0.997, which can meet the needs of practical use.
