摘要
文章对钢琴的实时检测进行了研究。采用物体遮挡光电传感器的方式,对琴键进行检测,可以使检测系统更加实时地对琴键信息进行反馈。利用单片机进行数据的存储和记录,将学习者的演奏琴键顺序音符传输给评估系统,使数据通过串口通信传递到LED屏幕上,使钢琴学习者能够更加方便、便捷地进行钢琴学习。
In this paper,the real-time detection of the piano is studied.Using the way of object shielding photoelectric sensor to detect the keys,which enables the detection system to feedback the key information more in real time.The single-chip microcomputer can be used to store and record the data,and the sequence notes of the learners'playing keys can be transmitted to the evaluation system,so that the data can be transmitted to the LED screen through serial communication,and thus piano learners can learn piano more conveniently.
