Desenvolvimento de sistemas de monitoramento empregando tecnologia LoRa em um protótipo tipo formula SAE

Abstract

Nowadays, the real time information is very important to follow the behavior of the systems that are part of our day to day. We can see in the industry, where a company can monitor its vehicles by satellite or, like in this work, in a race car. Telemetry systems allows vital signs and dynamic vehicle performance to be monitored remotely, in a constant way. Thus, the present work describes a study about the use of LoRa technology in the development of a computer interface telemetry system for the 2019 prototype of the UFSM Formula student team, and involves software design, programming, testing and manufacturing of system components. Information such as engine temperature, oil temperature, battery voltage, among others, are sent to a computer screen and displayed on a custom monitoring interface containing charts, gauges and indicators. In addition, was chose to use Bluetooth communication present in smartphones, to develop an application with a display to steering wheel screen and a monitoring screen for auxiliary telemetry. In this way, although the system has not enjoyed the maximum performance allowed by the LoRa module due to the implementation of high rates of data transmission and large packets, the main objective of collect data from multiple sensors of the prototype and communicate to a computer and a smartphone in real-time was achieved in a satisfactory manner, reaching the requirements requested by the project.
