Resumen
Actualmente, el problema del ahorro energético ha tomado una gran importancia en la industria debido al impacto que el derroche de energía tiene en el medio ambiente (Ministerio de Energía de Chile, 2018)
Bajo esta problemática, se propone crear un sistema práctico y de bajo coste que permita hacer un monitoreo a tiempo real del consumo eléctrico de uno o más nodos conectados a una red basada en CC2530 de Texas Instruments utilizando topología estrella y sensores ACS712 de efecto Hall, tal que permita llevar una estadística básica y expandible en una base de datos que además, permita enviar alertas de sobreconsumo por correo electrónico utilizando el protocolo SMTP.
En el mercado existen diversas alternativas para elaborar una red de sensores, tales como XBEE o ESP01 sin embargo, la tecnología CC2530 permite un menor consumo (24.3 mA) lo cual da una ventaja comparativa respecto a las alternativas existentes, minimizando el consumo del sensor.
La tecnología CC2530 dispone la capa física del proyecto, por lo que este trabajo incorpora el diseño de un protocolo de aplicación, un servidor que permita recibir el monitoreo y posterior almacenado y despliegue de los datos en un servidor HTTP, almacenando los datos en una base de datos MySQL.
Se implementó con una red de 2 sensores conectados a un nodo central, donde se logró medir cada un segundo los consumos, comparando las mediciones con un wattmetro comercial como control. Las cargas de prueba fueron consumos controlados en un rango discreto entre 10 y 500 Watts, donde se logró graficar una curva de consumo, tal de poder convertir a pesos, multiplicando por el valor del Kilowatt hora, con la capacidad de exportar la planilla MySql a Excel (CSV), dando lugar a un prototipo opensource de bajo costo con proyecciones de mejoras futuras.
Currently, the problem of energy saving has taken a great importance in the industry due to the impact that the waste of energy has on the environment (Ministry of Energy of Chile, 2018) Under this problem, it is proposed to create a practical and low-cost system that allows real-time monitoring of the power consumption of one or more nodes connected to a network based on Texas Instruments CC2530 using star topology and Hall effect ACS712 sensors, such that it allows to carry a basic and expandable statistics in a database that also allows to send overconsumption alerts by email using the SMTP protocol. In the market there are several alternatives to develop a network of sensors, such as XBEE or ESP01 however, CC2530 technology allows lower consumption (24.3 mA) which gives a comparative advantage over existing alternatives, minimizing sensor consumption. The CC2530 technology provides the physical layer of the project, so this work incorporates the design of an application protocol, a server that allows receiving the monitoring and subsequent storage and deployment of the data on an HTTP server, storing the data on a base of MySQL data. It was implemented with a network of 2 sensors connected to a central node, where it was possible to measure the consumptions one second, comparing the measurements with a commercial watt meter as control. The test loads were controlled consumption in a discrete range between 100 and 500 Watts, where it was possible to graph a consumption curve, such as converting to pesos, multiplying by the Kilowatt hour value, with the ability to export the MySql spreadsheet to Excel (CSV), giving rise to a low cost opensource prototype with projections of future improvements.
