摘要
为了监测某区域某频率段内声波信号的强弱,提出一种以C8051F060为控制核心的声波信号采集系统的设计方案。采用压力场声波传感器将可识别的声波信号转换为适当幅度的电信号,该信号经过由程控滤波器地处理后直接送至带高速ADC的单片机进行处理,最后以SYG2401281图形点阵液晶为显示器件实现声波信号的实时显示。
In order to monitor the strength of the acoustic signal within a certain frequency in a certain area, and put forward a kind of a design of acoustic signal acquisition system. Using the pressure field sensor converts the identifiable acoustic signals into the appropriate amplitude Electrical signals; the signals are sent to C8051F060 microcontroller. With the corresponding processing operations,software design,display circuit design,and taking the SYG240128 graphics dot matrix LCD as the display device. It achieves the acoustic signal collection and display function of the whole system.
