【Abstract】 A SoPC was constructed using FPGA,and the uC/OS-II operating system was ported to achieve the hardware and software design of a small fan speed intelligent control system based on brushless DC motor; Using DS18B20 temperature sensor to collect ambient temperature and automatically control the motor speed based on the ambient temperature; By using the HC-SR04 ultrasonic module to measure the distance between objects, it has been achieved that when an object approaches the fan to a distance of 8cm, the brushless DC motor automatically limits its speed and the buzzer sounds an alarm; The SU-03T speech recognition module was used to achieve voice control of motor speed; Through serial communication between FPGA and STM32F103C8T6 microcontroller controlled Wi-Fi module, environmental temperature, fan speed, distance alarm signal, and motor rotation direction data can be uploaded to Alibaba Cloud.更多还原
