结合智能终端和无线通信模块的便携式风速仪

Portable Anemometer Combined with Intelligent Terminal and Wireless Communication Module

风速测量在农业种植、工业生产、气象监测和风力资源等领域有着不可估量的重要性。然而,传统的风速测量所使用的设备普遍配件多、体积较大,不便于携带至工作现场进行测量。为此,采用HY16F19X系列单片机,完成了便携式风速仪的设计。该风速仪以HY16F198单片机为核心,通过带有磁轴的叶轮和工字电感的组合来完成风速信号的采集,信号经放大整形后由单片机接收并处理。另外,该风速仪还设计了温度测量单元,可对环境温度进行测量。风速值和温度值通过蓝牙模块发送至智能终端设备(手机或平板电脑等)显示和存储。该系统成本低、低功耗,安装携带方便,可长时间查看和存储测量数据。

Wind speed measurement has inestimable importance in the fields of agricultural planting,industrial production,meteorological monitoring and wind resources.However,the traditional equipment used for wind speed measurement generally has many accessories and large volume,which is not convenient to carry to the work site for measurement.For this reason,the HY16 F19 X series single-chip microcomputer(SCM)is used to complete the design of the portable anemometer.The HY16 F198 SCM is the core of the anemometer,and the wind speed signal is acquired through the combination of an impeller with a magnetic shaft and an I-shaped inductor.Then,the signal is received and processed by the SCM after being amplified and shaped.In addition,the anemometer is designed with a temperature measurement unit to measure the ambient temperature.The wind speed value and temperature value are sent to the intelligent terminal device(mobile phone or tablet,etc.)for display and storage through the Bluetooth module.The system has low cost,low power consumption,convenient installation and carrying,and can view and store measurement data for a long time.
