Abstract

This project proposes the development of a prototype of structural health monitoring using WSN (Wireless Sensor Networks), whose objective is to determine the state of a structure effectively, simply and without high implementation costs. The development of this device is carried out by means of an Arduino Uno, this equipment is used due to its storage capacity and adaptability since it is the one in charge of collecting the data by means of the sensors that will be connected to it. The sensors used for the elaboration of this project of titration, are the modules of vibration SW-420 chosen since in conjunction with an OPAMP LM393 helps to the detection of some vibration in the required threshold, these sensors of vibration are located on the structure to analyze, obtaining more exact measurement and precise data reason why they allow to determine the state of the same one, thanks to international norms which were used to obtain conclusions on the monitored structure. XBee devices are used for data transmission due to their low latency and great synchronization of predictable communication, since this application requires a high data traffic. Which are based on the 802.15.4 standard used to create point-to-point or point-to-multipoint networks, the configuration is done through the XCTU software achieving an open protocol communication, which are responsible for sending the information wirelessly. The information is stored in a SQlite database using the Phyton programming language, through the collection of data from the processing and transmission devices the Matlab program delivers comparative results with the international standards detailed in the investigation and thus determining the type of damage to the structure.
