Abstract
The Brazilian Agency for Industrial Development (ABDI) estimated that the implementation of Industry 4.0 in Brazil could result in annual savings of BRL 35 billion in repairs, BRL 31 billion in production efficiency and BRL 7 billion in energy savings, totaling savings of R$ 73 billion per year. The maintenance of structures can benefit from the innovations brought by Industry 4.0 by replacing costly preventive maintenance, in which specialists are called in based on a prior schedule, by predictive maintenance, in which a monitoring system verifies the condition of the structure in an automated way and specialists are only called in when there are signs of damage or potential failure. Applications include transmission towers, bridges and oil platforms. There is a rich literature containing studies that tackled various challenges in monitoring structural integrity. The concept of energy harvesting offers alternative sources or sources that need power redundancy. Connectivity problems via GPRS due to limited signal coverage by telephone operators can be mitigated through Low Power Wide Area Network (LPWAN) protocols. Electromagnetic interference caused by transmission lines resolved by means of Bragg optical fibers. Several signal processing methods have been developed in order to remove noise, identify damage, perform force identification, etc. In 2008 the Electric Power Research Institute (EPRI) developed a study of promising technologies for monitoring transmission lines. Among the sensors, the use of surveillance cameras, vibration sensors, inclination, leakage current and temperature were highlighted. As for data transmission, the study highlighted the use of Radio Frequency, WiFi and ZigBee. As this is an old study, it did not include more recent technologies specifically aimed at the IoT market that have low energy consumption and greater area coverage, such as LoRa, NB-IoT and Sigfox. This project proposes the construction of a scale transmission tower aimed at the development of customized structural integrity condition monitoring solutions. In this project, it is proposed to develop a monitoring system for electrical energy transmission towers based on technologies typical of Industry 4.0, namely Internet of Things (IoT).
