- W2391113144 abstract "Aiming at the features of current domestic water supply pipeline leakage detection by manual listening,i.e.low reliability and poor anti-interference,and according to the acoustic signal characteristic of the water supply pipeline leakage and the cross-correlation detection,this paper designs a leakage detector based on the TMS320VC5402.The detector uses modified periodogram to estimate the power spectrum of the pipe vibration signal and then determine whether there is a leakage.when positioning on the leakage point,two detectors are used to sample the pipeline's leakage signal at the same time and then cross-correlation algorithm is used to calculate the leakage point.The hardware scheme and the software chart of leakage-measurement system are provided.This detector comprises of DSP minimum system,data acquisition module,wireless communication module and MCU man-machine interface module.The test results show that this detector has a good detection capability and its locate error is within half a meter." @default.
