[Field of Invention]

The present invention relates to a stolen vehicle tracking device using a mobile phone capable of immediately detecting a stolen vehicle in real time. A patent application (No. 96-7285) has been made by the present inventor regarding a method of using mobile phone base station coordinates. This is a problem that needs to change the operating system of the exchange has been made possible the present invention that can be applied immediately and accurately know the coordinates of the stolen vehicle in real time.

In order to protect against vehicle theft accidents caused by the proliferation of automobiles, various types of anti-theft systems have been studied. Most of them are operated by a self-detection system, or recently, a pager, a satellite receiver, and a wireless data terminal are used. Although various methods of flashing emergency lights or tracking locations with radio detectors have been introduced in the case of theft reports, the primary focus has been on the prevention of self-theft. It was difficult to escape the city and arrested the vehicle, which resulted in material damages caused by car damage, and the radio wave detection method is limited in supplying it at a high price because it requires nationwide network construction for tracking.

Therefore, the present invention is the idea that there must be a social recognition that a car thefter is arrested immediately to prevent a car theft crime, and when a phone is made to the mobile phone of the present invention installed in a vehicle at the time of theft, it automatically receives a call and moves around. If you read the telephone base station value and the radio wave intensity value and calculate the location by itself or transmit the read data to the tracking center immediately in the form of voice and data, the existing national mobile phone network (including personal mobile communication and outgoing call) You can know exactly the location of the stolen vehicle and use the police to arrest it.

[Background of invention]

Even in Korea, the number of automobiles is close to 10 million and theft of automobiles is frequent and causing a lot of damages. Especially, thefts are becoming more frequent as vehicles are used for crimes or are subject to crimes. Various anti-theft devices have been put to practical use to prevent theft of the vehicle, which are largely inexpensive and have recently developed their own anti-theft detection system in various forms. As a result, it has reached the stage of tracking a vehicle, but it has been applied to only luxury vehicles in the US at a considerable cost, and there is a problem of establishing a nationwide tracking network.

Therefore, in order to solve the problem of self-detection, if the device is released during initial theft, there is no countermeasure and if the alarm responds frequently because it is not sensitive to theft, it may be ideal to track after theft like the latter. However, in the latter case, since a transmission / reception system and a separate tracking terminal have to be arranged in each region, there is a limitation in applying it at a high price and a huge tracking terminal facility cost is required to establish a national tracking network, which is practically impossible. It is possible to construct a nationwide tracking network, including underground parking lot, by using a mobile phone network without investing the facility cost, and the signal is weak to hide the satellite antenna in the car. The present invention has been made in that it is difficult to actually apply to the tracking device.

In other words, the ultimate social goal is to get rid of car theft, which is important for prevention, but through a complete arrest system, the thefter can't get rid of it by not knowing where the tracking / detection system is hidden. In the case of a vehicle, the present invention can be found by connecting to a corresponding mobile phone in a tracking device and calculating the current location by referring to nearby base station information.

[Purpose of invention]

It is an object of the present invention to refer to nearby base station information by connecting with a mobile phone mounted in a tracking device when the vehicle equipped with the vehicle tracking device is stolen using a wide range of mobile telephone networks (outgoing call, cellular, personal mobile phone). The stolen vehicle that can be tracked nationwide using the mobile phone network without receiving a separate tracking network by receiving the current coordinate value calculated in the form of voice and data from the tracking center and automatically displaying it on a computer map or reporting it to each police station. To provide a tracking device.

This is because the focus is on the arrest of the thefter, so the culprit cannot know where the arrester is installed in the vehicle. It is a stolen vehicle tracking device that can arrest a stolen vehicle on site by calculating.

If such a stolen vehicle tracking device becomes so common as a car black box, car thieves will not think of stealing the car until they remove it, which is hidden somewhere in the car. It is an object of the present invention that it can be done.

[Summary of invention]

The present invention connects the transmitting and receiving device of the mobile phone and the central processing unit for controlling the same, and additionally, by connecting the voice synthesis device with the voice input terminal, the mobile phone receives a call instead of ringing automatically when a predetermined instruction code is received. When entering, it reads the number of neighboring base stations and the radio wave intensity value and transmits the data in the format that is promised between voice and both systems, so that the tracking center can identify the location of the vehicle in real time. The built-in rechargeable battery enables to minimize the current consumption by controlling the rate of power supply and cut-off time in order to extend battery life.In many cases, the mobile phone does not receive perfect reception. Call the designated tracking center There may also be configured to notify the site value and the vehicle number, will be described in detail below the present invention will be described with reference to the accompanying drawings as follows.

Detailed description of the invention

The stolen vehicle tracking device of the present invention calculates its own coordinates by reading the neighboring mobile phone base station number and the radio wave strength value when connecting to the mobile phone in the vehicle tracking device and asking the current position using an existing mobile phone network. Or send the relevant data in the form of voice and data to the tracking center for calculation at the tracking center so that the location of the stolen vehicle can be known immediately. Unlike the existing system, using a mobile phone network does not require a new investment to build the tracking network. This is due to the fact that it can be tracked and connected nationwide, and the mobile phone network includes outgoing calls, cellular and personal mobile communications, and a rechargeable battery must be built in to enable tracking even when the car is turned off.

In case of using mobile phone, it can be used immediately by registering the phone to mobile communication only when the vehicle is stolen, and it can be traced and operated to terminate the phone after arrest. Each vehicle tracking device may have a different ESN and a phone number, and a method of registering and tracking a switch with a mobile phone ESN in the vehicle tracking device by operating the same phone number in a different ESN.

If power is supplied to the tracking device after theft of the vehicle, the rechargeable battery can be charged at all times without the need for additional power saving.However, when the vehicle battery is cut off, the rechargeable battery operates for a long time (at least 15 days). To achieve this, an ultra-low power design will be achieved, but by allowing the system to be powered on and off periodically, battery life can be prolonged by an on / off ratio compared to the way it is always powered.

In the case of a mobile phone, the system is configured to provide perfect incoming and outgoing calls.However, due to the limitations of the radio environment and the exchange, it is difficult to provide 100% incoming calls. Finding a tracking device, and when called, reverses the call to the vehicle center and transmits coordinates calculated based on the information of nearby base stations when the call is connected, thereby improving the vehicle tracking rate compared to using a mobile phone only. Private telephones can be applied.

In addition, due to the limitations of mobile phones, it is difficult to receive coordinate values outside the service area. In this case, the vehicle center additionally refers to the contents of the home location registration register (HLR) or visitor location registration register (VLR) of the mobile telephone exchange. It can be configured to locate a stolen vehicle.

Thus, if the stolen vehicle tracking device is configured using a mobile phone network, it is advantageous in terms of cost because it does not require a separate base station and network configuration for constructing a separate tracking network, and the base station number or the radio wave strength or the actual coordinate value calculated from the reference is voice. (Tokyo, North Lat) synthesized and transmitted to the data and converts it to data Modem or tone method, in the case of a digital phone can transmit the data in a short message communication method, etc. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings Same as

A schematic configuration diagram of a stolen vehicle tracking apparatus using a mobile telephone according to the present invention is shown in FIG. 1. A mobile telephone transceiver 2 having an antenna 1 for forming a call path with a tracking setter and a telephone is shown. ) And the central processing unit (3) controlling it, and reading the neighboring base station numbers and respective radio wave strengths in order to read the current real-time coordinate values of the tracking device, the absolute coordinate values of all the base stations of the mobile phone are recorded and the base station data By installing the coordinate calculation means (4) for calculating the current coordinate value by trigonometry with reference to the reference, when the arc is connected, the value of the coordinate calculation means (4) is read and synthesized by voice by the speech synthesis device (7) or the data processing device (8) transmit data in a format that can be recognized by the tracking center, or transmit all nearby base station data to the tracking center without using coordinate calculation means (4). The tracking center uses the base station number and the radio wave intensity data to determine the location by trigonometric method, and the charge / discharge control circuit 12 which controls the rechargeable battery 13 and the charge / discharge so that the vehicle power source 14 operates even when shut off. In addition, the power supply unit 11 cuts off the supply of the + power source 9 under the control of the central processing unit 3 and configured to perform a power saving function.

Instead of sending the values of the coordinate calculating means 4 by the reception of the mobile telephone transmitter / receiver 2, the central processing unit 3 calls the radio pager 6 instead of receiving the mobile telephone to increase the reception rate. When the call is made, the central processing unit 3 controls the mobile telephone transmitting and receiving device 2 to transmit to a predetermined telephone number (tracking center), and when the call is connected, the coordinate values of the coordinate calculating means 4 are read to synthesize the voice. The device 7 can be configured to synthesize voice or to transmit the data processing device 8 to a data format that can be recognized by the tracking center. In this case, the mobile phone transmission and reception device 2 can use an outgoing mobile phone. .

When the vehicle power source 14 is supplied to the tracking device after the vehicle is stolen, the rechargeable battery 13 is charged with the charge / discharge control circuit 12 while always operating without saving power, and the vehicle battery power source 14 is supplied. In this cut-off state, the power supply device 11 is configured such that power is periodically supplied to the system under the control 10 of the central processing unit 3 so that the battery 13 can operate for a long time. It is configured to extend the life of the rechargeable battery 13 by a ratio, and when power is supplied, a process of automatically registering the mobile telephone exchange is performed.

Since the mobile phone is used during the movement, it is configured to switch to the next cell even if it leaves the cell by the handoff function. For this purpose, the mobile phone always has information on neighboring cells, which is the base station's number, field strength, and in some communication methods. As it contains the absolute coordinate value information of the cell, by adding not only the information of one carrier but also the cell information of another carrier, the exact position can be calculated accordingly, and the coordinate calculating means 4 determines the absolute coordinate value of each cell of the operator. As a means for calculating the current position by using the inputted cell data, a separate transmitting / receiving end may be set to retrieve cell information of not only a mobile phone but also a call-only phone and a personal mobile communication.

2 is a program flow diagram for explaining the stolen vehicle tracking device using a mobile phone of the present invention in the standby state after initialization, when the car battery power is not connected, the system is periodically turned on and off by operating in a power saving mode. In this case, when a mobile phone is called or a wireless calling device is called, it is pointed out as a stolen vehicle. When a call is received or a call is made to a designated place and a call is received and a function code requesting data transmission is received, the coordinate value of the coordinate calculating means is read. It converts voice and data in the form promised by voice synthesis device and data processing device and configures transmission information to transmit unique number and coordinate value to tracking center, which is repeatedly transmitted until end code is input or call is terminated. .

As described above, the stolen vehicle tracking device using the mobile phone is connected to the mobile phone in the vehicle tracking device using the existing mobile phone network and asks for the current location. In other words, unlike existing systems using other wireless means, using a mobile phone network has the advantage that it can be directly connected to nationwide tracking and connection without new investment in establishing a tracking network. If it can be traced and nationwide network is established, two-way pager, frequency public communication, wireless data terminal, satellite communication device can be used as a transceiver.

If this stolen vehicle tracking device becomes universal like a car black box, the car thefter will not think of stealing the car until the device is hidden somewhere, and if it is made small, it will ultimately be stolen from society. I think it will contribute to the elimination of.

Although the present invention has been described in detail only with respect to the described embodiments, modifications and variations that are within the spirit and scope of the invention are apparent to those skilled in the art to which the invention pertains and such variations or modifications are limited by the appended claims. You must lose.
