In order to master the meteorological dynamic accuratelyand acquire the information of wind velocity real-timely and credibly,the wind velocity monitoring system based on ARM micro-controller was designed. The system used the three-cup wind speed sensor as sensor device,STM32 as controller,SP3485 transceiver and HAC-UM as communication transmission module. The measurement technology of wind velocity based on STM32,the general framework of hardware design and the realization method of system software were presented in the design. The design has realized to monitor the wind velocityin real time and accurately by capturing the frequency of the pulse with STM32 timer. After tested,the system has the advantage of low power dissipation,stable performance,high measurement precision,convenient extension function and so on.
