Diseño e implementación de un prototipo para el análisis de salud estructural de un puente a través de una red de sensores inalámbricos utilizando el software matlab.

Abstract

This project proposed the development of a prototype of structural health monitoring using WSN that would be a network of wireless sensors, whose objective was to determine the state of a structure efficiently, simply and without high implementation costs. The development of this device was carried out by means of an Arduino Uno, this equipment was used due to its storage capacity and adaptability since it was in charge of collecting the data by means of the sensors that were connected to it. The sensors used for the development of this project were the SW-420 vibration modules chosen because together with an OPAMP LM393 helped to detect any vibration at the required threshold, these vibration sensors were located on the structure to be analyzed, and that could obtain a more accurate measurement and more accurate data so they allowed to determine the status of it, thanks to international standards which were used to draw conclusions about the structure monitored. XBee devices were used for data transmission due to their low latency and great predictable communication synchronization, since this application requires high data traffic. Which are based on the 802.15.4 standard used to create point-to-point networks, the configuration was done using the XCTU software achieving an open protocol communication, which were responsible for sending the information wirelessly. The information was stored in a SQlite database using Phyton programming language, through the collection of data from the processing and transmission devices the Matlab program delivered comparative results with the international standards detailed in the investigation and the type of damage to the structure was determined.
