摘　　要：利用压电式传感器及低噪声低功耗放大器设计了漏水检测探头,使用A/D-D/A转换器TLV320AIC10芯片及TMS320C5402 DSP芯片等实现了两路音频信号实时采样及相关分析系统的硬件电路,采用C语言及汇编语言实现了系统软件设计.实验结果表明,该系统性能可靠,有较高的实用价值.Using piezoelectric sensors and low-noise low-power amplifier, a probe for leak location is designed. With A/D-D/A converter TLV320AIC10s and one DSP chip TMS320C5402 which receives the sampled data through McBSPO,the hardwired connection of the two-way real-time sampling and analyzing system for audio signals is accomplished. The software program of the system is completed by using assembly language in conjunction with C code. The experiment results indicate that the system is reliable and practical.
