Abstract
Los sistemas convencionales de iluminación vial no permiten el control de la intensidad de luz en función del tráfico de peatones o vehículos, sólo tienen dos modos de operación automático (prendido/apagado) dependiendo de la luz del día, y consumen una gran cantidad de energía eléctrica. En este artículo se describe el diseño, desarrollo, e implementación de un nuevo sistema de iluminación vial inteligente basado en tecnología LED, un dispositivo electrónico embebido inalámbrico (hardware) de bajo consumo energético desarrollado desde cero, y energía solar fotovoltaica. El dispositivo embebido incluye firmware especializado y un protocolo de comunicación inalámbrico energéticamente eficiente, que permite conformar una red de sensores infrarrojos de detección de peatones y vehículos, para el control y regulación de intensidad de las luminarias LED. Un piloto fue instalado en una calle aledaña al campus de la Universidad Privada Boliviana en la ciudad de Cochabamba, Bolivia, donde se realizaron medidas del consumo energético del sistema, que confirman un ahorro energético del 72.8% gracias al control inteligente desarrollado.
Conventional street lighting systems do not allow controlling the light intensity depending on the traffic of pedestrians or vehicles, only operate in two automatic modes (on/off) according to the availability of daylight and consume enormous amounts of electric energy. In this article, we describe the design, development and implementation of a new intelligent street lighting system that is based on LED technology, an energy-efficient embedded wireless control device (hardware) designed from scratch, and photovoltaic solar energy. The embedded device includes specialized firmware and an energy-efficient wireless communication protocol, that allows to form a network of infrared sensors to detect pedestrians and vehicles, so as to control and dim the LED luminaires. We implemented a pilot system in a back road of the campus of Universidad Privada Boliviana, in the city of Cochabamba, Bolivia, where energy consumption measurements confirm energy savings of 72.8% thanks to the developed intelligent control system.
