The system is a windsurfing control system. Through the control of fan speed, the angle of windsurfing can be changed by adjusting the wind power. This system uses AT89C52 chip as the core of the system control chip, angle acquisition and processing using ADXL345 three axis acceleration sensor array to the selection of medium speed axial fan motor as the braking source fan system, using LCD12864 liquid crystal display panels, the size of the angle for real-time display.
The key to the motor drive circuit, through the comparison and discussion of full, final selection of L298N driving module, through the microcontroller output PWM pulse, better realize the motor speed; and adding PID control, realize the optimization of control angle. Finally, several tests show that the system has fully met the design requirements, not only to complete all the basic and play part of the requirements, and increase the real-time display of duty cycle changes in the entire function.
