Acceleration Logger and Analyzer

Abstract

In the case of high acceleration values, it isimportant to obtain data on the vehicles used by third parties in order toprevent possible accidents. For this purpose, it is aimed to design anelectronic system which will record the acceleration values of a vehicle duringits journey and then to analyze it. Thanks to the accelerometer sensor placedin an experimental vehicle, the g force data that the vehicle was exposed towere obtained and analyzed by Arduino to determine which speeds the driverswere subjected to during the journey. The final product created in the study isan electronic device consisting of an Arduino, an accelerometer and an ArduinoSD card reader module. After the physical connection between the elements wereestablished, the Arduino interface was installed in the computer to obtain theinstantaneous acceleration values in the direction of the acceleration of theaccelerometer. After completing the physical installation of the circuit,different routes were determined within the scope of determined route in orderto observe the acceleration values for different situations. The axes in eachroute obtained were analyzed separately by Matlab and the acceleration valueswere plotted. According to the results of the analysis, a maximum of +0.22 /-0.34 g at the x-axis and +0.26 / -0.25 g at the y-axis and +0.15 / -0.17 g atthe z-axis were encountered during a normal driving. In contrast, in the caseof unsafe use of the same vehicle, the values of +0.41 / -0.63 g on the highestx-axis, +0.33 / -0.36 g on the y-axis and +0.18 / -0.18 g on the z-axis wereencountered. When the results obtained are shared with the sector and theirview are received, the results of our study have been shown to be supportive ofthe data that the companies have already pursued, and have the characteristicsthat can meet the needs of the sector.
