Acceleration Logger and Analyzer

Abstract

In the case of high acceleration values, it is important to obtain data on the vehicles used by third parties in order to prevent possible accidents. For this purpose, it is aimed to design an electronic system which will record the acceleration values of a vehicle during its journey and then to analyze it. Thanks to the accelerometer sensor placed in an experimental vehicle, the g force data that the vehicle was exposed to were obtained and analyzed by Arduino to determine which speeds the drivers were subjected to during the journey. The final product created in the study is an electronic device consisting of an Arduino, an accelerometer and an Arduino SD card reader module. After the physical connection between the elements were established, the Arduino interface was installed in the computer to obtain the instantaneous acceleration values in the direction of the acceleration of the accelerometer. After completing the physical installation of the circuit, different routes were determined within the scope of determined route in order to observe the acceleration values for different situations. The axes in each route obtained were analyzed separately by Matlab and the acceleration values were 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 at the z-axis were encountered during a normal driving. In contrast, in the case of unsafe use of the same vehicle, the values of +0.41 / -0.63 g on the highest x-axis, +0.33 / -0.36 g on the y-axis and +0.18 / -0.18 g on the z-axis were encountered. When the results obtained are shared with the sector and their view are received, the results of our study have been shown to be supportive of the data that the companies have already pursued, and have the characteristics that can meet the needs of the sector.
