Diseño de un prototipo para la geolocalización de adultos mayores con problemas de desorientación utilizando tecnologías basadas en el internet de las cosas.

Abstract

In the present work for getting the degree, the design and implementation of a prototype of geolocation for older adults who have problems of disorientation was made, through the use of various technologies related to the Internet of Things (IOT). It was initiated with theoretical research and subsequent validation with professional criteria in the field of geriatrics in order to know the group of older adults with disorientation problems to which it was intended based on the Global Deterioration Scale (GDS), the GDS 5 grade was selected as the recommendable; regarding the design, each of the elements was determined and technologies involved in the prototype, through a systematic comparison which allowed evaluating both the operating characteristics, the cost, the scope, in addition, a PCB using the EasyEDA tool thus obtaining a portable device, for this it is used the traditional method of ironing and transferring. As a result, a series of data in the form of coordinates was extracted with which it was possible to generate various alerts to have a monitoring based on events or movements in real time. The data obtained regarding precision were very good in favorable environments an accuracy of around 1m was obtained and in unfavorable environments an accuracy of 3m, the delay measurements obtained were between 1000 ms and 4000 ms. From the tests carried out, it was concluded that the implemented system it is precise, reliable, easy to use, scalable and with a wide field of application. It recommends for future work the miniaturization of the prototype to obtain a prototype of lower cost and size, but with the same or better performance.
