Implementación de un prototipo electrónico de seguridad para bicicletas.

Abstract

An electronic security prototype for bicycles was implemented, for such, it was developed a system that, through a mobile application developed in Android Studio, allows the user to activate or deactivate the alarm system. The system was implemented with an Arduino Mega as the main control board, a motion sensor and a buzzer that emits an alert tone, it also has a SHIELD SIM808 module for sending messages, phone calls, as well as the GPS position. When the movement of the bicycle occurs, it is detected by the motion sensor, generating an alert tone and then making the call and sending text message to the owner of the vehicle, message containing a link that directs the user to the map in the mobile application, where the location of the bicycle at that moment is detailed. As an additional option for system activation, there is a Nextion screen for password access. The device has a lock that immobilizes the rear wheel of the bike; It also has an auto-recharging system that allows the user to recharge the battery that feeds the prototype through the movement of the wheel, for which a dynamo and a solar panel are used, thus having a battery autonomy of approximately 4.59 hours. It has been made different tests to the prototype such as: accuracy of the GPS system, detection of movement before different situations, validation of the opening and closing of the lock, using the mobile application or by entering password and of text message and calls receiving time. In conclusion, the prototype has an efficiency of 99.17%, complying with the objectives set for its implementation, allowing users to feel greater security when leaving their bike unattended. It is recommended to be aware of new technologies that allow generate a lower-dimensional prototype.
