Implementación de un prototipo de red inalámbrica para la identificación, supervisión y localización en tiempo real de personas con padecimiento de Alzheimer.

Abstract

At the present graduation work an implementation of a prototype of a wireless network was developed in order to identify, supervise and locate people who suffers from Alzheimer. The system permits to register and to store personal data in a database manager on the web (MySQL), the programming carried out on the website and in a native mobile application admis the access to the information through the user’s authentication, to identify people; A unique emergency code recorded in labels of near field communication (NFC) is used. For the information process an Arduino board was implemented with the connection to a GPRS module for the transmission of data and a pulse sensor for the detection of the vital signs of the person. The system will provide through a mobile telephony network infrastructure GSM/GPRS in a wireless form and in real time information of the coordinates of the location of the person and cardiac pulse, in intervals of 3 minutes to be stored on the web. The information is shown in graphic form on a map and in a table of numerical values when accessing the website. From the tests carried out, it is concluded that the time of authentication and data searching is 2 seconds from a Wi-Fi network and 3 seconds from a mobile phone network. The work presents an error from one to two meters in the coordinates, when the location of the person is carried out and matches with similar commercial systems. It is concluded that the implemented network can become a help tool for the care of people with Alzheimer disease. It is recommended to carry out studies which will permit to reduce the size of the implemented device and incorporate sensors for the measurement of other physiological variables.
