Therefore, theft of the object can be prevented by detecting the movement of the object and outputting a warning sound, and the location of the object can be tracked using the positioning system at the time of theft.

Description

Anti-theft device and method using positioning system {device for preventing from stealing using global positioning system, and method of the same}

The present invention relates to an anti-theft device and method using a positioning system, and more particularly, to theft of the object by grasping the position of the object using a global positioning system (GPS) module provided in the object. An anti-theft device and method for preventing the same.

The modern ICT sector is undergoing rapid development and change. The main reason for the change is the development and popularization of computers, which leads to the active development and application of information and communication technologies using computers. An example is GPS, which is a positioning system using satellite communication.

GPS is a system that arranges four or five satellites in each orbit at six orbital planes inclined at 55 degrees with the earth's equator, and communicates with four or more satellites anywhere on the earth. GPS can receive signals containing specific codes from GPS satellites to calculate your current location (longitude, latitude, altitude) at some point in time, especially if you're on the move.

Originally, GPS was developed for military use, but recently, it has been applied in a wide range of fields such as providing simple location information, auto navigation and traffic control of aircraft, ships and automobiles, and collision prevention of oil tankers. In addition, by providing the location information of individuals and vehicles through the network of GPS and mobile communication terminals to police stations, hospitals, etc., it is usefully used in areas such as emergency rescue, traffic information, distribution and logistics.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the basic configuration of an anti-theft device using a positioning system according to the present invention.

Referring to Figure 1, the anti-theft device using a positioning system according to the present invention, the mode selection unit 100, the movement detecting unit 110, the alarm sound output unit 120, the position transmission unit 130, the power supply unit ( 140, an auxiliary power supply unit 150, and a control unit 160.

For convenience of explanation, hereinafter, a television (hereinafter referred to as "TV") will be described by way of example.

The mode selector 100 has a fixed mode and a moving mode function, and provides a setting and / or changing means of the mode. The setting and / or changing of modes such as fixed mode and moving mode can be selected by input means such as a switch provided in a remote controller or a TV. The fixed mode is selected when the TV is fixed, and the moving mode is selected when the TV moves. In order to change the set mode, the user must input a command such as a password, and the mode can be changed if it matches the preset password. This allows the user to perform the TV anti-theft function with a simple operation.

When the TV movement occurs when the mode of the mode selector 100 is selected as the fixed mode, the movement detection unit 110 detects the movement of the TV and outputs a movement detection signal move_sig. Figure 2a is a block diagram showing a detailed configuration of the movement detection unit of the anti-theft device using a positioning system according to the present invention. Referring to FIG. 2A, the movement detecting unit 110 includes a first contacting unit 112, a second contacting unit 114, and a signal output unit 116.

The first contact portion 112 is installed on the fixed portion where the TV is fixed, and the second contact portion 114 is installed on the outer surface of the TV. The first contact portion 112 and the second contact portion 114 are first conductive pads and second conductive pads, respectively, and are electrically connected to each other. The signal output unit 116 outputs a movement detection signal move_sig when the first conductive pad 112 and the second conductive pad 114 are separated and the power is turned off. The signal output unit 116 may be configured as a relay.

The warning sound output unit 120 outputs a warning sound for a predetermined time by a control signal of the control unit 160 when the movement detection unit 110 detects a movement of the TV and outputs a movement detection signal move_sig. When a warning sound occurs due to a malfunction of the user, the user may release the warning sound by inputting a password using an input means such as a remote controller. That is, when the preset password matches the password input for releasing the warning sound, the warning sound is released.

The warning sound can be output for a predetermined time (for example, one of three minutes, one hour, or continuous) according to the user's setting. It is desirable that the user input a password even when the warning sound output time is changed. When the mode of the mode selector 100 is selected as the moving mode, if the TV moves, no warning sound is generated and the location transmission function is not performed.

Figure 2b is a view showing a TV as an example of the configuration of the movement detection unit of the anti-theft device using a positioning system according to the present invention. Referring to FIG. 2B, the second conductive pad of the TV is mounted to the first conductive pad in the direction of the arrow and electrically connected thereto. In FIG. 2B, the first conductive pad is installed on the flat surface (fs). However, in the case of the wall-mounted TV, the first conductive pad may be installed on the wall.

When the movement of the TV is detected, the position transmitter 130 receives the position information signal position_sig of the TV from the GPS satellite and transmits the position information of the TV. Figure 3 is a block diagram showing a detailed configuration of the position transmission unit of the anti-theft device using a positioning system according to the present invention. Referring to FIG. 3, the location transmitter 130 has a GPS module 132 and a transmitter 134.

If the GPS module 132 outputs the movement detection signal move_sig from the signal output unit 116 and the warning sound is not released after a predetermined time elapses, the controller 160 generates the GPS driving signal gps_sig. The GPS module generates position information by receiving the position information signal position_sig from the GPS satellites by the GPS driving signal gps_sig.

The transmitter 134 transmits the position generated from the GPS module 132 to a GPS server connected to a police station or a security company. The GPS satellites simultaneously generate a position information signal (position_sig) composed of two different frequencies. The position information signal (position_sig) consists of a signal of 1.57542 GHz frequency known as L1 carrier and 1.2276 GHz frequency called L2 carrier.

The power supply unit 140 is a device provided to supply power to the mode selection unit 100, the movement detection unit 110, the alarm sound output unit 120, the position transmission unit 130, and the control unit 160. The power supply unit 160 supplies power so that the movement detecting unit 110 detects whether the first conductive pad and the second conductive pad are separated. In addition, by receiving power from the power supply unit 160, the GPS module may perform a reception operation of a signal transmitted from a GPS satellite. 1 illustrates that power of the power supply unit 140 is supplied to each component through the control unit 160 for convenience. However, power can be supplied directly to each component.

In the above-described embodiment, the present invention has been described based on electronic products for convenience of description. However, the anti-theft device and method using a positioning system according to the present invention can be applied to notebooks and artworks. Typically, the notebook is provided with a power supply 140, such as a power supply for receiving power from a battery and an external power cord mounted on the notebook itself. The power supply unit 140 of the artwork may receive power from the outside or may receive power from the battery.

The auxiliary power supply unit 150 supplies power to the movement detecting unit 110, the warning sound output unit 120, the position transmitting unit 130, and the control unit 160 for a predetermined time when the power of the TV is turned off. By providing the auxiliary power supply 150, the normal operation of the anti-theft device, such as the generation of a continuous alarm signal and the transmission of location information when theft is possible.

When the movement of the TV is detected and the movement detection signal move_sig is output, the controller 160 outputs a control signal for causing the warning sound output unit 120 to output a warning sound. At this time, the controller 160 outputs a control signal to stop the output of the warning sound if the password entered by the user and the preset password on the TV to match the warning sound. In addition, the control unit 160 outputs a control signal if the warning sound is not released, and outputs a control signal for transmitting the current position information by receiving the position information signal position_sig.

Figure 4 is a flow chart showing an embodiment of the anti-theft method using a positioning system according to the present invention.

Referring to FIG. 4, the TV is installed such that the first conductive pad 112 attached to the position where the TV is to be placed in contact with the second conductive pad 114 provided on the bottom surface of the TV. Thereafter, the user sets and / or changes the fixed mode or the moving mode through the mode selection unit 100 (S400). Typically, the user selects the fixed mode. When the first conductive pad 112 and the second conductive pad 114 are separated (S410), the controller 160 checks whether the mode of the mode selector 100 is the fixed mode (S420).

If it is determined in step S420 that the fixed mode is the signal output unit 116 of the movement detection unit 110 outputs a movement detection signal (move_sig) (S430). When the mode selection unit 100 is selected as the movement mode in operation S400, when the second conductive pad 114 is separated from the first conductive pad 112, the signal output unit 116 may move the movement detection signal (move_sig). Does not output

The warning sound output unit 120 outputs a warning sound for a predetermined time (for example, one of three minutes, one hour, or continuous) by the movement detection signal move_sig (S440). Beep output time can be adjusted by user's password input. If the password preset by the user and the password input by the user to cancel the warning sound match (S450), the alarm sound output is stopped. This is to release the warning sound when the alarm sound is output by the user moving the TV by mistake during the anti-theft function. If the mode selection unit 100 is selected as the movement mode in step S400 or if the password input in step S450 matches the preset password, the warning sound does not occur or stops.

If the warning sound release command is not input after receiving the movement detection signal position_sig, the controller 160 outputs the GPS driving signal gps_sig. When the GPS module receives the GPS driving signal gps_sig, the GPS module receives the position information signal position_sig from the GPS satellite (S460). The position transmitter 130 generates a position information including a latitude and longitude coordinate value of the current position from the position information signal position_sig and transmits the position information to a GPS server provided to a police station or a security company. (S470).

Referring to another embodiment of the anti-theft method using a location information confirmation system according to the present invention, the warning sound can be output regardless of the mode selection. In other words, when the second conductive pad 114 is separated from the first conductive pad 112, the movement detecting unit 110 outputs a movement sensing signal move_sig when the fixed mode or the moving mode is set. Then, the control signal of the control unit 160 confirms whether the mode selection unit 100 is set, and if it is determined that the fixed mode, the warning sound output unit 120 outputs a warning sound.

According to the anti-theft device and method using the positioning system according to the present invention, when the anti-theft function is set, it is possible to prevent theft primarily by generating a warning sound when the movement of the electronic product is detected. In addition, when a warning sound occurs due to a mode selection and a user mistake, the user may select a mode and release the warning sound through a user confirmation process such as a password input. In addition, if a command for releasing a warning sound is not input, current location information is generated and the location information is transmitted to a GPS server provided in a police station or a security company. This can help locate the stolen electronics.
