Although there has been vehicle anti-theft problem before, but with the promotion of their technology, the traditional means of anti-theft precautions have been unable to meet the needs of the anti-theft market now, so we need a more effective anti-theft system, we have studied a GPS Location-based vehicle anti-theft system. The anti-theft system is in different ways from the past, when the cars are stolen,it can track and report the position of the car in real-time, so that made the thief difficult to succeed.This paper introduces a new and effective anti-theft method. A GPS-based, using GSM digital mobile cellular communications network to provide a short message by wireless data communication, and positioning information and the transmission of orders. Vehicle location anti-theft system on the structure and composition of the working principle and gave a brief on the ARM Embedded System of GPS data extraction and the approach on detection and alarm.This system will effectively send information to the alarm center by GSM. The main task of anti-theft system is how to effectively detect the theft occurred and the first time, the stolen information will be sent to the central anti-theft and vehicle owners.Based on the Linux embedded operating system, using the advantages of GSM network that is large coveraged and high-speed communication, the system realizes interactive information between the monitoring center and car terminals in real-time. And the effectiveness of the system and stability have been fully able to meet the requirements of morden anti-theft system.
