Resumo
Este trabalho desenvolveu um protótipo de um correlacionador de sinais aplicados a vazamento em tubulações de água aterrada. Para tal foi analisado o SoC Zynq, utilizando a placa Minized juntamente com um conversor analógico-digital, Pmod AD1, um módulo GPS, Pmod GPS, um clock em tempo real, Pmod RTCC e um modulo acelerômetro Pmod NAV. Nesta análise foram utilizados modelos criados no software Xilinx Vivado, baseados em Intellectual Property blocks, e o software Xilinx SDK. A partir dos modelos desenvolvidos foram realizados testes com o propósito de validar o sincronismo entre as placas. Inicialmente testou-se um modelo simples apenas utilizando a placa e o módulo Pmod AD1, sendo o teste realizado para verificar a resolução do relógio da placa Minized. Em seguida foi feito o experimento com a placa Minized e o Pmod RTCC visando o sincronismo entre as placas. Os testes de sincronismo foram finalizados utilizando-se o conjunto Minized, Pmod RTCC e Pmod GPS, que obteve bons resultados. Para a finalização da análise da correlação de sinais verificou-se a utilização do Pmod NAV para a aquisição de dados com testes em bancada, apresentando resultados experimentais satisfatórios.
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.
