Description

Location tracking system for missing vehicles}

The present invention relates to a location tracking system for a stolen vehicle. More particularly, the present invention relates to a location and a movement path of a vehicle in a central control station by receiving a specific frequency signal generated from a transmitter installed in a secret location of a vehicle at a receiving station installed in each region. The present invention relates to a location tracking system of a stolen vehicle that enables a vehicle to recognize the vehicle in real time, thereby quickly recognizing that the vehicle is intentionally damaged or stolen.

In general, GPS (Global Positioning System), which is a satellite navigation system, and a system that tracks the position of a vehicle by receiving satellite signals through wired / wireless communication networks, are respectively provided on six track surfaces that are inclined at 55 ° with respect to the earth's equator. When four or five satellites are arranged and four or more satellite signals are received from anywhere on the earth, the system can determine the absolute position of the earth, and the GPS receiver receives a signal containing a specific code from the GPS satellites. It is a system that can calculate your current location (longitude, latitude, altitude) at any point.

GPS is widely used for navigating aircraft and ships, and recently, it is widely used for the purpose of tracking the location of a stolen vehicle through a mobile communication network as well as providing geographic information.

The GPS receiver mounted on the vehicle to track the location of the stolen vehicle has an antenna connected to a GPS receiver (not shown) with a coaxial cable facing the GPS satellite so that the GPS receiver (not shown) can be smoothly received from the satellite. Or, since the structure is exposed to the outside of the vehicle body, it is possible to track the location while grasping the movement path of the vehicle through a base station that can receive a GPS when the vehicle is stolen.

However, if the person who cuts off the vehicle knows the positioning function of the GPS receiver, it is possible to devise a method of weakening and disabling the GPS receiver function by damaging an antenna or coaxial cable exposed to the outside of the vehicle. Accordingly, there is a problem that the operation of the GPS receiver becomes impossible and the location tracking of the stolen vehicle is impossible.

The present invention has been made in view of the problems caused by the damage of the above-described conventional stolen vehicle tracking device, the purpose of which is to select a secret place of the vehicle having a self-diagnosis function and equipped with a transmitter for transmitting a signal of a specific frequency And it is to provide a location tracking system of the stolen vehicle that can determine the movement path and location of the vehicle in real time by installing the receiving end for receiving the frequency signal for each region.

The present invention for achieving this object is equipped with a transmitting device for transmitting a signal of a specific frequency at all times by the power supplied from the battery by selecting the engine room of the vehicle or an enclosed place of the room, the transmitting device A self-diagnosis circuit is installed to detect intentional damage by detecting damage or replacement of the vehicle's attachments, and the frequency signal generated from the transmission device concealed in the vehicle is received by a number of regional receivers installed in a certain area along the roadside. By monitoring the central control station through the site, it can track the location of the vehicle in real time by inquiring the natural frequency signal of the transmitting device mounted on the vehicle to the central control station and recognize deliberate damage such as changing the license plate of the vehicle arbitrarily. As a result, the vehicle is quickly coped with theft.

Hereinafter, the location tracking system of the stolen vehicle of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing an overview of the location tracking system of the stolen vehicle according to the present invention, and FIG. 2 is a block diagram of the location tracking system of the stolen vehicle. 10) is connected to the battery of the vehicle supplying power irrespective of starting the engine, and then select and mount a secret place that is not exposed to the eyes of other people, such as the engine room of the vehicle or an enclosed place in the room, and the transmission device 10, the self-diagnosis circuit 11 is installed to detect the attachment of the license plate, such as the vehicle theft, which can be easily forged by the sensor, and operate the transmitting device 10 by the sensor.

The specific frequency signal transmitted from the transmitter 10 is received at any one of a number of receivers (L1 to Ln, M1 to Mn ... Z1 to Zn) installed for each region by using structures such as street lights and electric poles on the roadside. The received specific frequency signal is transmitted to the central control station 20 through a wide area repeater (G1 ~ Gn) that has jurisdiction over the region, and compares the vehicle with a unique number for each frequency and the frequency receiving location with the stored data. The position of the vehicle can be recognized in real time through the monitor.

For example, when the vehicle information is prepared for each natural frequency of the transmitter 10 mounted on the vehicle, the information about the stolen vehicle is inquired to the central control station 20 while the data is inputted to the computer of the central control station 20, The inquiry signal sent from the control station 20 is sent to the regional receivers (L1 to Ln, M1 to Mn ... Z1 to Zn) through the wide area repeaters G1 to Gn, and then, at the transmitter 10 mounted on the stolen vehicle. It receives the signal of the corresponding frequency generated, and communicates the signal again with the central control station through the repeater, it is possible to track and grasp the movement of the wanted vehicle in real time, and to the self-diagnosis circuit (11) built in the transmitter It is possible to detect that the attachment supported by the artificial damage is made easier to retrieve the stolen vehicle.

In addition, the transmitter 10 for tracking the stolen location of the present invention is installed in a secret place of the vehicle so that only the owner and the related person of the vehicle can know whether the vehicle is installed, thereby preventing damage caused by exposure of the transmitter during theft of the vehicle. It can be safe for enough time.

On the other hand, when the receiver that can recognize the natural frequency signal transmitted from the transmitting device is applied to the switchgear of the doorway through which the vehicle passes, there is also an unmanned doorway monitoring function that can selectively pass only the vehicle allowed access. Modifications are merely possible to implement easily from the present invention.

The location tracking system of the stolen vehicle according to the present invention inputs a unique frequency signal transmitted from a transmitter installed secretly in a vehicle to a central control station via a receiver installed in each region and a wide area repeater, thereby tracking the location of the vehicle when stolen. This easy and self-diagnosis circuit built in the frequency transmitter makes it possible to recognize the act of damaging the attachment of the car, so that it is possible to respond quickly to theft, and to prevent damage to the location tracking device as much as possible. have.
