To solve the problem of the current infants’ intelligent monitoring products’ low recognition rates for the infants’ crying,an infants’ intelligent monitoring system which can recognize the infants’ crying accurately was designed.The RT5350 chip was used as processor,the PAP7501 chip was used to capture the video signal and audio signal.A Linux kernel was ported to the system,the multi-threaded programming techniques was used to program the application programs.The Mel frequency cepstrum coefficient (MFCC) was extracted as the characteristic parameters, the dynamic time warping (DTW) algorithm was used as the recognition algorithm.The system can communicate with the cloud server to realize the infants’ crying alarm function,and it can also communicate with the user's terminal device to realize the transmission of video data and audio data.The users can monitor the infants effectively with the help of the system.
