Sistemas embutidos de muito baixo consumo para redes LPWAN

Abstract

Low Power Wide Area Networks (LPWANs) is the common designation of a set of solutions that seek to connect thousands of low energy, low cost and low bandwidth transmission systems. Despite belonging to the same group, LPWAN technologies are quite diverse and, as such, it is necessary to determine their characteristics to be able to identify which one is the best suited for each particular case. In this dissertation, the development of a low consumption metering system was proposed, with a life expectancy of 10 years. The system shall measure the water consumed by up to 4 di erent households and will use a LPWAN solution exchange messages with a central supervisory system. The consumption of the system depends on several con guration parameters. It is possible to reach the life expectancy through an appropriate customization of the hardware, namely by using adequate clock sources for processing and communication.

Low Power Wide Area Networks (LPWANs) é a designação de um conjunto de soluções que procuram ligar milhares de sistemas de baixo consumo energético, de baixo custo e de baixas necessidades de transmissão. Embora sejam colocadas no mesmo grupo, nenhuma LPWAN é igual e, como tal, é necessário determinar as características de cada uma para que seja possível identicar em que situações quais são as preferíveis. Nesta dissertação propõe-se o desenvolvimento de um sistema de baixo consumo, com uma previsão de vida de 10 anos, que irá fazer contagem de água de até 4 habitações diferentes. Este sistema faz uso das soluções LPWAN para enviar e receber mensagens. O consumo medido do sistema é dependente da sua configuração, sendo possível atingir objetivo de vida parametrizando adequadamente o hard- ware, nomeadamente no que respeita à velocidade de relógio usado para o processamento e comunicação.
