说明：  该系统为一个帆板控制系统，通过对风扇转速的控制，通过调节风力大小达到改变帆板角度的目的。本系统以AT89C52单片机作为系统的核心控制芯片，利用ADXL345 三轴加速度传感器来的采集、处理帆板角度，选用中速轴流风机电机作为风扇的制动源，系统显示采用LCD12864液晶，用于实时显示帆板的角度大小。 对于关键的电机驱动电路，经过充分的比较与论证，最终选用驱动模块L298N，通过单片机输出PWM脉冲，更好地实现了电机的调速；并且加入PID控制，实现了控制角度的优化。最后经过多次测试表明，系统完全达到了设计要求，不但完成了所有基本和发挥部分的要求，并增加实现了实时显示占空比全程变化的功能。
(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.)
