Diseño e implementación de un sistema electrónico de supervisión e identificación vehicular con una comunicación inalámbrica.

Abstract

An Electronic System for vehicle supervision and identification with Wireless Communication was designed and implemented in order to understand the characteristic data of the auto motive, supervise, and alert the users about changes in the internal environment of the automobile. The sensor and plates were chosen through the comparative method and characteristic analysis. The module was divided into the following blocks: supplies, sensors, display, processing, storage, and communication. For the implementation the Arduino platform was used, it provided 5 volts of direct current to the system. For the supply block the main source was the vehicle battery and also an internal battery for electrical redundancy. For the sensor block Alcohol, Carbon Monoxide, Temperature, and Positioning were handled. For visualizing a Liquid Cristal Display (LCD) was implemented; the processing block had an Arduino Mega 2560 Card. For the storage block an Electrically Erasable and Programmable Reading Memory (EEPROM) of Arduino was used. The communication block added a Bluetooth transmission card and a Global Mobile System (GMS). The vehicle personalized information was storage in the EEPROM memory which could be visualized through Bluetooth. The environmental values of the car cabin obtained by sensors were observed through LCD screen or the communication block by sending a request via Bluetooth or GMS, thus generating alerts to the users through a text message. In the communication tests it was determined that the Bluetooth communicates to a distance of 5 meters and it matches only if is within the range are of the telephone. For future devices it is recommended to use a date base for tracking the vehicles which have this device incorporated.
