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 paper, a method of realizing the design of the windsink control system by using angle sensor and DC motor control is introduced. The design of the STC89C52 microcontroller as the main chip, through the angle sensor MMA7361 and AD converter TLC549 windsurfing angle measurement, the use of measurement results to adjust the PWM value to generate different duty cycle PWM wave DC motor speed control, and thus Adjust the size of the fan wind speed so that the windsurfing different corner. At the same time using LCD12864 to display the relevant information. Each module constitutes a closed-loop control system that enables fast and efficient control of the windsurfing corner.
