Abstract

This work developed a prototype of a signal correlator applied to leakage in buried water pipes. The Zynq SoC was analyzed using the Minized board together with an analog-to-digital converter, Pmod AD1, a module GPS, Pmod GPS, a real-time clock, Pmod RTCC and a Pmod NAV accelerometer module. For this analysis we used models created in the Xilinx Vivado software, based on Intellectual Property blocks, and the Xilinx SDK software. From the developed models tests were carried out in order to validate the synchronism between the boards. Initially, a simple model was tested using only the board and the module Pmod AD1, and the test was performed to verify the resolution of the Minized board's clock. Then the experiment was performed using the Minized board and the Pmod RTCC aiming the synchronism between the boards. In order to finalize the synchronization tests, we used the Minized set, Pmod RTCC and Pmod GPS, which presented good results. For the conclusion of the analysis of the correlation of signals, the use of the Pmod NAV for the data acquisition was verified and then benchmarked, presenting satisfactory experimental results.
