Desenvolvimento de um sistema de telemetria para aquisição de dados em voo aplicado ao aerodesign

Abstract

A flight data monitoring system is crucial for maintaining situational awareness action of a crew member. However, if these data can be easily observed will increase assertiveness in decision making. For a team of aerodesign competition, having a system that allows this monitoring will provide the development of a project with better quality, increasing the chances of obtaining a good position during the competition. This work presents the development of a system of telemetry applied to aerodesign for the team of the Universidade Tecnológica Federal do Paraná (UTFPR). For the development of this system two microcontrollers Espressif Systems (ESP) 32 are used, which communicate with each other over a Long Range network(LoRa). One of the microcontrollers is the data transmitter and is connected to sensors that provide navigational aid data, such as barometric pressure information, speed, altitude, air temperature, aircraft attitude to terrain, bow and location. The other microcontroller receives the data and transmits it to a processing unit that shows the user, through a friendly graphical interface, the information exchanged. The node-based programming tool, Node-RED, was used for programming the data processing software and the graphical interface. During the practical test, it was obtained a good result in the transmission of the data read by the data acquisition and transmission unit. It was possible to observe the data being plotted in real time in the graphical interface. The data was saved in a spreadsheet for further analysis.
