用matlab采集语音，信号加噪去噪，以及fft变换(With Matlab acquisition Voice, the signal plus noise denoising, and fft transform)

通过串口来通信，控制PLC，单片机各种伺服变频等实现运动。(Through serial port to communicate, control PLC, microcontroller servo frequency conversion and so on to achieve movement.)

说明：  113、基于51单片机老人生理智能监控GSM短信 本设计由STC89C52单片机电路+火焰传感器电路+加速度传感器+心率传感器电路+SIM800A_GSM模块电路+电源电路组成。 该系统实时监测老人是否跌倒，是否周围有火以及心率情况。 1、如果火焰传感器检测到火焰，则GSM向特定手机发送：Fire！ 2、如果ADXL345检测到老人跌倒了，则GSM向特定手机发送：Fall！ 3、如果心率传感器检测到老人心率高于120，则GSM向特定手机发送：High Heart！ 4、注意本设计一次上电上述情况每个只能触发一次上报短信，不会连续发送，防止反复发送，请放心使用。 5、短信处理过程有GSM信号灯指示。 6、GSM模块是SIM800A，该模块和SIM900A电路程序完全兼容外观外形一模一样。(GSM SMS for elderly physiological intelligent monitoring based on 51 MCU This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit. The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time. 1. If the flame sensor detects a flame, the GSM sends: fire! 2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall! 3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart! 4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use. 5. SMS processing process is indicated by GSM signal light.)

matlab功能很强大，里面包含了很多程序，可以更好的理解和求解(matlab function is very powerful, which contains a lot of procedures, you can better understand and solve the)
