Diseño de un sistema electrónico para mitigar el robo de teléfonos celulares

Abstract

This technical project, the design of an electronic anti-theft system of mobile phones, consists of two fundamental parts: transmitter control, and an actuator. To better understand the operation of the system, it has been set in the most common scenarios in which tearing-style thefts and robberies are recurrent. The first scenario occurs in small places with large crowding, being public transportation the most common example as we know it is there where the theft of cell phones tends to occur more frequently. For this scenario, the search for the mobile phone depends on an audible signal emitted by the phone case that is part of the electronic anti-theft system and is attached to the stolen phone. This signal will be activated from a transmitting device (bracelet), by radio frequency communication between the bracelet and the phone case. The legitimate owner of the stolen mobile will have the bracelet, which will be used to command the actions in the phone case, as the search for the mobile phone continues. The second scenario occurs in little crowded places or when the victim is distracted by using the mobile phone, it is there where snatching usually occurs. The escape of the criminal will be interrupted by applying an aversive stimulus (electric shock) on the person who stole the mobile phone. This stimulus will be emitted by the phone case and controlled with the bracelet worn by the owner of the stolen mobile phone.
