摘　　要：提出一种基于现场可编程门阵列的异常声音探测系统,通过对采集的现场声音信号进行时域和频域分析并提取异常声音的特征,将异常声音从正常声音中分离出来进行识别。当发生异常声音后能发出控制指令进行报警保护或相关的过程控制,实现在工农业的安全防护、声目标识别、机器智能等领域的预定声音事件探测。Presents the abnormal noise detection system based on FPGA, by collecting on-site audio signal in time domain and frequency domain analysis and extraction of abnormal noise characteristics of the abnormal noise from the normal separation of voice identification. After the event of abnormal noise control instructions can be issued to police protection or related to process control to achieve in the industrial and agricultural security, voice target recognition, machine intelligence and other areas of the target sound event detection.
