智能机器人识别舞蹈音乐节奏的方法
摘要：
本发明是智能机器人识别舞蹈音乐节奏的方法，它先采集麦克风音乐信号通过两级OP放大器，第一级OP放大器放大后的增益＝15倍的音乐信号，又经第二级OP放大器放大后的增益＝60K/(1K+电阻R19的阻值)；通过模数A/D转换后接入CPU进行数据处理；将经CPU数据处理后的信号进行傅立叶变换，检测为舞曲慢四；将检测为舞曲慢四信号通过H桥电路控制电机启停，实现机器人动作。优点：方便地实现对麦克风音乐信号的放大和采集。对采集的数据进行FFT变换，并利用变址法和离散傅立叶变换系数WN程序化等方法进一步提高FFT变换的计算的速度。经多次试验证明本方法能实现对慢三和慢四舞曲的识别；并制作机器人。
摘要（英）：

The present invention provides a method for intelligent robots to identify the rhythm of dance music, and the first music collection microphone signals through two OP amplifier; firstly, the present invention collects musical signals of a microphone and then lets the signal go through two class of OP amplifier; the gain after being amplified by the first class of OP amplifier is 15 times as large as the music signals; and the gain after being amplified by the second class of OP amplifier is 60 K / (1K plus the Rmin of the resistance R19); the musical signals after being converted by a modulus A / D are connected with the CPU to conduct data processing; the musical signals and the data are processed by the CPU data, can be conducted the Fourier transform to be detected as blues music; the music signal detected as blues music can be controlled to be on or off by a control motor of the H-bridge circuit to realize the movement of a robot; the present invention has the advantages that the amplification and collection of musical signals of microphone can be realized conveniently; the collected data can be conducted FFT transform, and the speed of calculation of FFT transform can be improved further by using indexing method and the programming method of discrete Fourier transform coefficient W N , and so on; a plurality of tests can be proved that the method can realize the identification of waltz and blues, and can be used to make robots.
