Sistema de monitoramento do uso de salas e laboratórios e controle da movimentação de equipamentos

Abstract

This study presents the development of a system composed by hardware and software to monitor the use of rooms and laboratories and control the movement of equipment that have Radio Frequency Identification (RFID) tags. The goal is to automate the space usage monitoring to increase building safety and energy efficiency, as well as to facilitate mobile equipment location control such as those available in the laboratories. In the proposed system, a monitoring unit is installed in each monitored location, which is coupled to a 125 kHz RFID tag reader and to an LCD display, as well as temperature, relative humidity and light sensors, gas and smoke detectors and sensors of doors and windows opening. The project uses as central command and processing unit a Raspberry Pi board programmed in Python language, which is responsible for the acquisition and interpretation of data from different sensors, the reading of RFID tags and the communication with a server via TCP-IP interface. The server has a database that enables remote data access and monitoring system configuration through a Web platform. The system developed in this study allows the modular installation of sensors from the use of different devices in places where its needed. Besides, its functionality will not be compromised by the installation of such devices, which represents a low-cost solution along with excellent benefits.
