Description

System and Method for Preventing Vehicle Theft Using GPS Receiver}

The present invention relates to a vehicle anti-theft system, and more particularly to a vehicle anti-theft system and method using a GPS receiver for tracking the location of a stolen vehicle using a GPS receiver.

Recently, an autonomous navigation system for vehicles that uses a universal positioning system (GPS) satellite to identify the position of a moving object and matches it on a road map and displays it has been actively proposed.

GPS is a satellite navigation aid system that was originally developed for military purposes. There are two types of positioning services provided by GPS: standard positioning services and precision positioning services. Among them, standard positioning services using relatively inaccurate Coarse Acquisition (C / A) codes are used for civilian purposes. Open to use, anyone with a C / A code receiver can easily find their location and time anywhere on Earth. Accordingly, navigation systems using GPS have been widely used in recent years, and positioning technology using GPS satellites has been used in various fields such as high precision time synchronization, geodetic, navigation of ships, navigation devices of mobile vehicles such as automobiles and aircrafts.

There are 24 GPS satellites, with an altitude of about 20,000 km and a 12-hour cycle, which means that more than four satellites are visible at any time on Earth. In addition, GPS satellites continuously transmit information about time, its own orbit information, general orbital information of all satellites, reliability of each information, and other error correction factors necessary for navigation.

When the GPS receiver is mounted on the vehicle, the position information of the vehicle is continuously monitored through the GPS satellites, and the traffic information can be grasped in real time by the position information of the vehicle. Therefore, the driver of the vehicle equipped with the GPS receiver can easily know where the traffic jam is severe or where the communication is smooth, so that the overall vehicle communication can be performed smoothly.

On the other hand, the number of vehicles has increased rapidly in modern times and is becoming a necessity of modern man. However, as the number of vehicles increases, theft accidents of vehicles increase, resulting in a large amount of property damages of industrial automobile owners that load and carry expensive goods as well as ordinary cars. In particular, stolen vehicles are used for various crimes, so if they are not promptly arranged, mental and physical damages are inflicted on innocent people, and thus human consumption is enormous.

In order to arrange stolen vehicles, they can be arranged in connection with the police station that receives and handles the stolen reports or randomly announces the number of stolen vehicles through public broadcasting so that the stolen vehicle can be found. However, such a method requires a lot of manpower for arranging the vehicle and causes economic loss, and therefore, it takes a long time to arrange the stolen vehicle.

The present invention has been made to solve the above-described problems, when a change in the abnormality of the vehicle equipped with a GPS receiver is detected, by notifying the owner through a wireless terminal to prevent theft of the vehicle and to easily track the stolen vehicle There is a technical problem to provide a vehicle anti-theft system and method using a GPS receiver.

Another technical problem of the present invention is to prevent the loss of the vehicle by stopping fuel interruption to the vehicle when detecting the abnormal change of the vehicle to prevent the vehicle thief from driving.
