基于单片机的帆板控制系统的设计

The Design of Sailboard Control System Base on MCU

文中介绍了一种利用角度传感器与直流电机控制实现帆板控制系统设计的方法。本设计以STC89C52单片机为主控芯片,通过角度传感器MMA7361和AD转换器TLC549对帆板的转角进行测量,利用测量结果调整PWM值产生不同占空比的PWM波对直流电机的转速进行控制,从而调节风扇风速的大小使帆板产生不同的转角。同时采用LCD12864对相关信息进行显示。各个模块构成闭环调节系统,可以实现对帆板转角快速,有效的控制。

In this article, it is introduced that one design method of using the angle sensor and DC motor control sailboard .The STC89C52 microcontroller is used as the core component in this design. The angle of sailboard is measured by bangle sensor MMA7361 and AD converter TLC549. The measurement results to adjust the DC motor speed by PWM wave witch is controlled by different duty ratio value of PWM ,so as to adjust the size of the fan speed to produce different comer windsurfing. At the same time using LCD12864 to display the relevant infomlationo Each module to form a closed loop control system can control the sailboard fast and effectively.
