Abstract
Con el presente Trabajo Fin de Máster se pretende abordar el diseño y la implementación de un sistema de iluminación inteligente en carreteras capaz de ofrecer la mejor iluminación en diferentes ubicaciones atendiendo a factores tales como la actividad medida o la cantidad de luz disponible. Con este tipo de sistemas se pretende reducir la contaminación lumínica de las ciudades, el coste de mantenimiento y el consumo de las luminarias instaladas en las carreteras actuales, así como abordar otros posibles problemas derivados del sistema de iluminación tradicional. Este trabajo se ubica en el contexto de las Smart Cities del Internet de las Cosas en donde sistemas que cuentan con sensores y actuadores mantienen una comunicación para cumplir con un funcionamiento determinado. Tratan, por tanto, de mejorar la calidad de vida de los habitantes y salvaguardar la de otros seres vivos. Para abordar el problema se partirá de un diseño modular genérico para cada región de carretera que cuenta con sensores y actuadores que ayudarán a determinar las condiciones óptimas de iluminación de una región en un momento dado. Los nodos de cada región estarán conectados en red para propagar información relevante para el funcionamiento del sistema. Además, será posible recoger información de actividad de tramos, mandar información de forma periódica a un servidor y comunicar a los dispositivos el estado actual del tramo de carretera. También se van a tratar otros aspectos relevantes tales como la comunicación con dispositivos externos por buses de datos con distintos protocolos, el uso de un protocolo de comunicación, las características de un sistema operativo de tiempo real y la programación en un entorno multihilo.
In this thesis, an intelligent street lighting system capable of providing optimal lighting conditions to drivers will be designed and implemented. To achieve this behavior the system would measure road activity and the amount of light available. The purpose of this system is to reduce light pollution, maintenance cost and power consumption of currently installed and traditional road lights. Other related problems will also be addressed. The behavior of this system is related to Smart Cities in the context of the Internet of Things where devices with sensors and actuators can communicate important messages to the network and as such cooperate to achieve the desired behavior. Their purpose is to improve people’s lives and protect those of other living beings. To tackle this issue, we will create a generic modular piece of hardware for each region of the road that has sensors and actuators helping us determine the optimal lighting conditions always. The hardware of each region will be connected to the same network to be able to send important information that will be needed for a correct system operation. It will also be possible to get important data related to road activity, send data to a server in a periodic manner and communicate the current road state to devices. Other important matters will be addressed like for example communication with external devices using different transmission protocols, the use of a communication protocol, the features of a real time operating system and multithread programming.
