Identifiering och simulering av en låskistas profil

Sammanfattning: The fact that companies test their products is important for our society to function well. It is especially important when products will be used in the welfare, when human health is at stake. This thesis is about tests performed on Phoniro's lockbox. Phoniro's lockbox is a product used in the home service as it can lock and unlock a door it is attached to without a key, with the help of an engine which can be activated with Bluetooth. When the project started, Phoniro's test doors were used to perform tests. These test doors were not a good representation of how doors are in reality. Due to this reality, the first step in the work is to identify a door's profile, specifically how much power the motor needs to turn in the various angles of the latch as it turns the lock. This was done by turning a lock with a motor equipped with an encoder and a current sensor on the motor driving card. An Arduino was used to control the motor and measure these values. In order to perform the tests an engine is attached to Phoniro's lockbox. The engine has the task of counteracting the engine in the lockbox with as much current it takes to turn the lock at the angle the motors is located. The result of the profile measurements are lists of data which can be plotted in a graph were the difference between doors can be seen.
