Diseño e implementación de un sistema electrónico de alarma e inmovilización vehicular controlado por un teléfono inteligente con comunicación Bluetooth

摘要

This project of Electrical-Electronic Engineering in Telecommunications consists in the implementation of an electronic alarm and vehicle immobilizer technologically innovative because it employs Bluetooth technology and the use of smartphone. The purpose of this work lies in the replacement of the radio frequency device "traditional Remote Control" for an application installed on the smartphone of the vehicle´s owner.This thesis was developed in three segments. The creation of an intuitive and invulnerable smartphone application; the establishing of an autonomous and indecipherable Bluetooth connection between the smartphone and the microcontroller; and, the implementation of a microcontroller and an electronic circuit that is multitasking, low power consuming, compact and resistant to climatic factors.Once completed the process described above, the results are integrated to check if the objectives set at the beginning of this research were achieved with satisfaction.The hardware and software used in this thesis were: Microsoft Visual Studio 2008 IDE, the Samsung i637 smartphone with Windows Mobile 6.5, the RN-41 Bluetooth module, the ATMEGA8 microcontroller, the compiler Bascom, Proteus simulator and a professional electronic circuit.
