Sistema inteligente para monitoração, gerenciamento e controle de iluminação pública e análise de parâmetros da rede elétrica

Abstract

The present paper proposes a system to manage, control and monitor a group of LED luminaires of a street lighting system, being able to control the light intensity of the luminaire and monitoring the power consumption, detection of pedestrians, fault conditions, environmental parameters such as temperature and humidity. Additionally, the system contains a voltage sensor coupled to the grid in order to monitor and manage the power quality parameters. Basically, the system can be divided in three essential parts. The first one regards the smart module, called in this work as SM, which has the responsibility to sensing the parameters stemming from power grid as well as luminaire. The second part is the control module (CM), which has the aim to coordinate the data received from each smart module, storing and subsequently sending the data to the supervisory system. Besides, the control module also has temperature and humidity sensors in order to check and register environmental conditions, providing, in this way, reliability of the measured data. The supervisory system (SS) consists of the final part of the proposed system and it is responsible to save the data in a local memory, to analyze and to monitor problems or even possible faults and sending commands to each CM and/or a respective SM. With the aim to evaluate the proposed system, it was performed experiments to demonstrate the system operation as well as the quality analysis capability. Due to the energy savings potential provided by the technology, it was also studied the economic feasibility of the prototype, aiming a future commercial product. The results have shown that the proposed system is scalable, flexible and efficient.
