红外无线传输下钢琴自动演奏机器人设计

Design of automatic piano playing robot based on infrared wireless transmission

文章旨在研究智能制造在钢琴自动弹奏音乐上的应用前景。乐谱数据采用自设红外通信标准进行信号传输。系统通过红外发射控制模块对乐谱数据信号进行红外调制后发射,红外接收控制模块接收、解调红外乐谱数据信号。单片机读取、解析数据信号控制继电器开关,驱动执行机构对钢琴键盘执行乐谱设定的时序升降操作,实现乐谱红外无线传输下的机器人自动演奏钢琴。该设计安装方便,造价低,性能稳定,智能化程度较高。

The purpose of this design is to study the application prospect of intelligent manufacturing in piano automatic playing music.The music score data is transmitted by the self-set infrared communication standard.The system transmits the music score data signal after infrared modulation through the infrared transmitting control module,and the infrared receiving control module receives and demodulates the infrared music score data signal.The singlechip reads and analyzes the data signal to control the switch of the relay,drives the executing mechanism to execute the sequential lifting operation set by the music score on the piano keyboard,and realizes the automatic piano playing of the robot under the infrared wireless transmission of the music score.The design has the advantages of convenient installation,low cost,stable performance and high intelligent degree.
