Design of the Active Audio Signal Sensor and its Application in the Correlation Algorithms for Water Leakage Survey

Abstract:

Using piezoelectric sensors and low noise power amplifier, a probe for leak location was designed. With A/D-D/A converter TLV320AIC10s and one DSP chip TMS320C5402 which received the sampled data through McBSP0, the hardware connection of the two way real time sampling and correlation analyzing system for audio signals was accomplished. The software program of the system was completed by using assembly language in conjunction with C code. The experiment results indicate that the system is reliable and practical.
