Abstract

A real-time signal acquisition system based on MS320VC5416 DSP is designed for the functional requirements of portable underground pipe water leakage detector. Realization of the IIR digital filter algorithm based on DSP is proposed, at the same time, the key technologies of filter order, filter algorithm, sample frequency, clock frequency are also analyzed. Testing on-the-field and simulation analysis show that real-time, stability and antinoise capabilities of the system meet the design requirements.
