Description

Location device for stolen vehicle using wireless pager and city phone.

The present invention relates to a device for confirming the location of a stolen vehicle, and in detail, by configuring the positioning device to be mounted on the vehicle by using the reception function of the pager and the transmission function of the city phone, The positioning device sends the stored vehicle number and alarm code to the city phone base station and transmits it to the city phone base station management device and management server, so that the location of the stolen vehicle can be quickly and easily checked to recover the stolen vehicle early. It is not to be used for a second crime.

In the present invention, the stolen vehicle is an example to which the positioning device can be applied for convenience of description, but of course, not only a car, but also an object that can be moved arbitrarily or arbitrarily, for example, Miana, a probationer, mentally or physically inconvenient. It can be used to track the location of people, animals, valuables, and various objects, and to identify the movement route, and the effects of the operation will be identified as well.

As it is well known, as the penetration rate of automobiles is improved, theft cases of automobiles are increasing. Accordingly, there is a problem that not only the owner's personal damage is caused but also a second crime using a stolen vehicle occurs. In an effort to prevent theft, automobile antitheft devices have been proposed and put into practice in the past.

For example, by installing a shock sensor and a voltage fluctuation sensor in a main part such as a car door, when the door is opened or an external shock is applied, an alarm mounted on the car operates to be alerted for a predetermined time. It has been practical to induce people who pray for theft to give up their theft and escape.

In the case of the anti-theft device, the alarm sound is generated only for a predetermined time due to the impact generated when the door is forcibly opened or the door is opened. If you cut off the power line or damage the alarm sound circuit to make it useless, you cannot expect the anti-theft effect of the vehicle. Moreover, even if the alarm system is normally operated when the vehicle is stolen, other problems such as starting the car Since the function is normal, the escape is possible, so it is not a fundamental anti-theft measure, and the vehicle is stolen for help.

Accordingly, an object of the present invention is to provide an anti-theft vehicle positioning device capable of quickly or easily checking or tracking the current position (moving position or stop position) of a vehicle which has already been stolen, without theft of the vehicle thief.

In order to achieve the above object, the location of the stolen vehicle can be confirmed by using a reception function of a wireless pager having a high reception rate and a unique identification number and a city phone transmission function that can transmit data to a city phone base station that is installed in close proximity to a point organization in the city. Configure the device.

In addition, the present invention is a relatively small transmission and reception radius of about 150m, but instead of the city phone base station installed in public telephones and telephone poles scattered throughout the city in the dot organization (thousands to tens of thousands of city phone base station is installed in each city. By making full use of), you can quickly track the current location of the stolen vehicle in about 150m distance.

Since the pagers only need to receive a call signal for positioning, unnecessary functions such as a display function, an alarm function, a text service function, a vibration function, a selection function, etc. are eliminated and only the antenna and the receiver module are used.

In addition, in the present invention, the city phone transmitting unit constituting a part of the positioning device is a means for transmitting a data such as a vehicle number and an alarm code wirelessly by means of a positioning request (wireless call), not a voice call. Functions such as a radio link setting unit for transmitting and receiving data by establishing a radio link with the city phone base station 8, a memory unit for storing a vehicle number and an alarm code, and propagating the vehicle number data and alarm code data to the city phone base station Eliminate unnecessary functions other than the city phone transmitter to reduce power consumption, manufacturing cost, and volume, and the city phone transmitter can be in standby state with minimal power if a wireless call signal (location signal) is not input to the positioning device. To reduce power consumption.

In addition, the memory unit for storing the vehicle number data and the alarm code data is to use a semiconductor memory that can freely write or erase data and can be modified (modifiable).

In the above, the alarm code is for identifying the call code or the alarm code at the city phone base station, and when the alarm code is sent, the city phone base station recognizes the alarm state for positioning rather than the call state and processes the signal.

In addition, when the call signal is received by the receiver module of the positioning device, the city phone control unit operates the city phone transmitter in standby state (SWITCH OVER), and when the city phone transmitter is operated, it sets a wireless link with a nearby city phone base station and sets a vehicle number and an alarm. Send the code.

In addition, the battery for the positioning device, which is the key to miniaturization, can be easily installed by miniaturization using a small size, and not easily found by the installer.

On the other hand, when the vehicle is stolen, when the positioning device is called by a general telephone or a wireless calling system, the receiver module of the positioning device operates the city phone transmitter in standby state (SWITCH OVER), and the city phone transmitter is connected to the wireless link setting unit. By establishing a wireless link with a neighboring city phone base station, when the wireless link is established, the city phone transmitter transmits the vehicle number and the alarm code stored in the memory unit to the city phone base station, and then disconnects the wireless link. It is determined that the call mode is not determined, and transmits its ID to the city phone base station management device in addition to the vehicle number and the alarm code, and the city phone base station management device according to the location number (address) according to the vehicle number and alarm code and the ID of the city phone base station. The current position of the vehicle (movement position and stop position of the vehicle) ), So that the stolen vehicle can be blocked early from being used for crimes.

And a data input unit 16 for inputting a vehicle number and a non-call identification alarm code of the vehicle in which the positioning device 2 of the present invention is installed at the input terminal of the city phone transmitter 12, A memory unit 10 for storing the vehicle number and the alarm code data inputted to the data input unit 16 is connected, and the memory unit 10 is a semiconductor having a nonvolatile structure capable of freely writing or erasing data (modifiable). Try to use memory.

In the above, the alarm code is for identifying the call code or the alarm code in the city phone base station 18, and when the alarm code is input, the city phone base station 18 is in an alarm state for locating a stolen vehicle instead of a call state. It recognizes and transmits not only its own I / D signal but also the vehicle number data and the alarm code data transmitted from the positioning device 2 to the city phone base station management device 20.

On the other hand, one end of the city phone transmission unit 12 is connected to a wireless link setting unit 22 for establishing a radio link with a nearby city phone base station 18, and when linked with the city phone base station 18, the vehicle number stored in the memory unit 10 And the alarm code data to be transmitted to the city phone base station 18.

In the above, it is preferable that the transmitting and receiving antennas 14 and 6 are housed in a case in the form of a loop so that they are not cumbersome or cumbersome when the present positioning device 2 is installed. Of course, the transmitting and receiving signals are not attenuated or interfered with. The transmitting / receiving antennas 14 and 6 may be integrated or separately installed within the range of not being provided.

In addition, the power supply unit 24 to be operated by the positioning device 2 of the present invention may be used by drawing the power of the vehicle, but the wiring is difficult and may be detected by criminals, so that the battery may be used on its own but may be replaced periodically. In addition, the battery is preferably small so that the volume of the positioning device 2 is greatly reduced so that it is easy to install and not easily seen.

In addition, the reason why the transmitter is used as a city phone transmitter in the present invention is that the transmission and reception radius is about 150 m, but rather narrow, located in scattered places dotted around the city, and installed in public telephones and telephone poles (thousands of thousands per city) To tens of thousands of city phone base stations are installed.) It is possible to quickly track and confirm the current location of the stolen vehicle at a distance of about 150m.

In the present invention, the receiver module 4 having a unique identification number needs only to receive a positioning call signal, and the city phone transmitter 12 also has only the city number base station and the alarm code data necessary for the vehicle location confirmation. ), So that unnecessary call functions (audio functions), display functions, alarm functions, text service functions, vibration functions, selection functions, and the like are eliminated. The power consumption and volume can be reduced by maintaining the standby state until the control signal is inputted from).

That is, in the case of the city phone transmitting unit 12 constituting a part of the present invention positioning device 2, the voice call is not the main purpose, but the city phone base station 18 sends data such as a vehicle number and an alarm code by a location request (radio call). Since it is a means for transmitting to the minimum necessary functions, for example, the city link base station 18, the radio link setting unit 22 for transmitting and receiving data by setting the radio link, and the data input unit 16 for inputting the vehicle number and alarm code ), The memory unit 10 for storing the input vehicle number and alarm code, and unnecessary functions other than the city phone transmitter 12 capable of transmitting the vehicle number data and the alarm code data by radio waves to eliminate power consumption and volume. To reduce the number, using the data input unit 16 to input and store the vehicle number of the vehicle on which the positioning device (2) is installed.

In the present invention, the positioning device 2 is installed in a secret place, for example, the inner corner of the trunk or the bottom of the seat while the radio call signal propagates without large attenuation so that it is not easily visible to the criminal.

Since the city phone base station 18 used in the present invention is installed in public telephones and telephone poles which are located in a dot organization in various places in the city instead of having a relatively small transmission and reception radius of about 150m around (thousands to tens of thousands of city phones for each city) The base station is installed.) Since the current position of the stolen vehicle can be checked (or tracked) at any time, the action can be promptly detected (detected), so that the stolen vehicle can be prevented from being used for the purpose of crime.
