摘　　要：为实现对帆板角度的精准控制以及实时显示,本文设计了一种抗干扰能力强、能够快速响应的角度自动控制系统。本系统采用STC89C52单片机作为核心控制器,LM7805和LM7812提供+5V和+12 V电源,通过按键设置帆板的角度,P3022-V1-CW360角度传感器实时采集角度信息,实时角度和设定角度以及PWM波的占空比由LCD1602进行显示,利用PID反馈调节机制控制单片机输出的PWM波送入L298N电机驱动芯片,通过改变电机的转速改变实时风力,进而改变帆板的角度如果帆板角度超出60度,立刻进行声光报警提示。经实验测试表明,本系统可以完成对帆板角度的快速调节,系统响应时间小于5 s,角度相对误差小于10%,整个系统具有良好的稳定性以及快速响应性能,实现了设计要求。To achieve precise control of sailboard angle and real-time display,this paper designs a kind of strong anti-interference ability,fast response angle automatic control system.The system uses STC89C52 microcontroller as the core controller,LM7805 and LM7812 provide+5 V and+12 V power supply,press the key point by setting sail,real-time acquisition of angle P3022-V1-CW360 angle sensor information real time,angle and setting angle and the duty ratio of PWM wave by LCD1602 display,using PID MCU control output feedback regulation mechanism of PWM wave to L298N motor driver chip,by changing the motor speed change real-time wind,and then change the angle of the sailboard sailboard angle exceeds 60 degrees if,immediately after the sound and light alarm.The test shows that the system can complete the quick adjustment of sailboard angle,the system response time is less than 5 seconds,the angle error is less than 10%The whole system has good stability and fast response performance,and realizes the design requirements.
