Desenvolvimento de protótipo de baixo custo de sistema de detecção de instabilidade de solo em infraestrutura e dutos enterrados

Abstract

This paper presents the project for the development of a low-cost prototype of a system for detection of ground instability and abnormal disturbances in buried infrastructures. The scientific study aims to find solutions that can prevent possible accidents, which have the potential to cause damage, interrupt the operation, or even bring loss of operational perfor mance of buried infrastructures, so that it is possible to conceive a system that has the potential to be employed in real conditions. All the components of the system, the theoretical and prac tical principles of its operation, the objectives and gains resulting from the project are pre sented in a structured way. First, the theoretical basis of the technologies used is shown, with emphasis on the measurement of soil pressure using a resistive pressure sensor, based on the ESP32 platform for data acquisition, processing and sending via Wi-Fi communication net work to a monitoring center. These components will be confined in an acrylic box filled with sand, in order to simulate a real pipeline segment, subjected to traffic pressure, erosion, vibra tions, as well as other unnatural vibrations or disturbances, of lesser or greater intensity. The relevant information will be displayed in a web interface, using HTML markup language. Next, in methods and materials, the project development stages are presented, as well as the materials, equipment and software used. Afterwards, in project implementation, the method ologies used for the study are detailed, as well as how the components should interact to col lect the data necessary for the scientific study. The conditions and limitations of the theoretical model and its differences in relation to the real conditions of the natural environment will also be informed. Next, in results obtained, the data of the project in its full operation is shown and analyzed. Finally, it is concluded through the data obtained that the proposed solution, applied the necessary improvements and changes to its operation in the natural environment, can be tested in real conditions so that it can be used in industry and infrastructures around the world.
