摘要
本文主要讨论了木材加工中的声音识别问题,利用短时傅立叶变换和快速傅立叶变换算法对锯条的断裂声进行识别,采用现在广泛使用的32位ARM9微处理器S3C2410来构建声音识别报警系统,结合实际设计了一套识别报警系统,详细介绍了系统的硬件设计,驱动程序的编写,识别算法的应用和整个嵌入式Linux系统的移植。
In this paper, we mainly discuss the problem of voice recognition. We recognize the fracture sound of saw blade using algorithm of Short Time Fourier Transform and Fast Fourier Transform and construct the sound recognition and alarm system by 32-bit microprocessor S3C2410.So we Combine with practical situation to illustrate that the hardware design of system, the program of driver, the recognition algorithm of application and the porting of whole embedded Linux system.
