A low-cost Smart Security Automobile Tracking by Global Positioning System

摘要

The paper aims to design a smart security automobile warning system via global positioning system (GPS). The vehicle theft prevention and warning system by GPS controlled by the microcontroller. This system consists of the keys and the electronics key radio frequency identification (RFID), which is a device before unlocking into the code protection system, which has a keypad to enter the 4-digit code controlled by the microcontroller. The user can enter the code to corrected and can use the key to start the engine. The users can enter the number code (XXXX) to turn on the system, which can be incorrectly entered 3 times if the user enters the wrong code again. After that, the system will sound a siren with a loudness of 120 dB to protect safety. An impact force sensor (18010P) install to the glass of windows, which detected the attract force more than is 8.5 N. The microcontroller operates via the GSM telephone system, which is sent Short Message Service (SMS) to alert the latitude and longitude of the car’s position via the GPS module to the smartphone. The vehicle owner can follow up on the vehicle on a Google map. This system can be called by using the global system for mobile (GSM) communications system and the car’s electric power system to turn on or turn off the system to stop the engine of the vehicle. The error of a smart security automobile system has 3.30 percent due to the connection of the telephone signal error.
