Abstract
Chile es un país propenso a temblores y terremotos que frecuentemente causan daños a la infraestructura e incluso pueden causar daños a seres humanos y al ganado. Por lo tanto, es un objetivo deseable desarrollar sistemas de alerta temprana y monitoreo de terremotos. Este proyecto tiene como objetivo probar el desarrollo de una red de sensores inalámbricos (WSN) utilizando una plataforma Libelium® para obtener, transmitir y recolectar datos de eventos sísmicos en un sitio web. Se analiza la viabilidad de poder muestrear, transmitir y almacenar información sísmica para su visualización usando dos protocolos de comunicación inalámbrica, Zigbee y GPRS (General Packet Radio Service). Para el despliegue y analisis de información almacenada del evento sísmico se desarrolla y ensaya una aplicación web, para lo cual, se utilizan algoritmos de procesamiento de señales, con el fin de encontrar patrones que permitan comparar los datos sísmicos.Nuestros resultados indican que generar una alerta temprana utilizando la red implementada depende en gran medida del método de acceso a la comunicación que se va a utilizar. Mientras que GPRS tiene una amplia cobertura, la latencia es el principal problema, mientras que Zigbee provee una tasa de transmisión mayor y más confiable a con cobertura territorial más limitada, dependiendo de las características de los enlaces.
Chile is a tremor and earthquake prone country that frequently cause infrastructure damage and may even take a toll of humans and livestock. Therefore it is a desirable goal, to develop early warning and monitoring systems for earthquakes. This project is aimed at testing the development of a wireless sensor network (WSN) using a Libelium® platform for obtaining, transmitting and collecting seismic event data on a website. Two wireless communication protocols, Zigbee and GPRS (General Packet Radio Service), are tested in order to analyze the feasibility of being able to sample, transmit and store seismic information for display on a website, which runs a web application for the characterization of the seismic event is developed and tested. Signal processing algorithms are used to find patterns of seismic events.Our findings are that generating early warning depends heavily on the communication access method to be used. While GPRS has an extensive coverage, latency is the main issue, whereas the Zigbee protocol provides a higher and more reliable data transmission, although at the expense of more limited coverage, depending on the wireless link characterisitcs.
