基于单片机的帆板控制系统设计

Design of Control System of Sailboard Based on SCM

利用STC12C5A60S2超低功耗单片机输出的PWM波的占空比控制风扇的转速,使帆板与垂直平面形成一定的夹角,通过SSA6060AH单轴倾角传感器检测电路得到帆板的实际角度值,从而实现对角度的精准控制,测量结果采用8位共阴数码管实时显示。实验结果表明,该系统性能稳定、测量精度高。

The rotational speed of fan was controlled by the duty ratio of PWM wave which was the output of STC12CSA60S2, the ultra low power consumption microcontroller, which made the sailboard and the vertical plane form a certain angle. The actual angle was detected by single shaft angle sensor SSA6060AH, so as to achieve precise control of angle. The results displayed on 8 bit common cathode led. The experimental results showed that the system was stable with high measuring accuracy.
