Description

Loss and Theft Prevention Device and Prevention Method of Notebook Computer

The present invention relates to a device for preventing and preventing the loss and theft of a notebook computer. More specifically, a notebook computer that is relatively high in the risk of loss and theft is alarmed when a certain distance from the owner causes a loss and theft. And a method for preventing and preventing the loss and theft of a notebook computer.

The spread of portable computers has become commonplace, and the use of only a small number of users for special purposes has become commonplace, and the spread of portable computers has become widespread. In addition, notebook computers have surpassed the desktop top in terms of performance, increasing the opportunities for general users and becoming indispensable for life.

Therefore, a lot of notebook computers that have the advantages of portability are used a lot, but when you move the place is often moved to the current location.

In this case, the conventional notebook computer has a problem that there is a risk of loss and theft. In addition, there is a risk of theft due to its light weight and high price.

However, the conventional notebook computer has no theft prevention function, and has only the power management function and the password function for security to use the power for a long time when carrying.

Therefore, an object of the present invention is to solve the conventional problems, by adding a function to prevent theft and loss in the notebook computer to prevent the loss and theft by the alarm to sound when a certain distance away from the owner to the notebook computer. An object of the present invention is to provide an anti-theft and anti-theft device for notebook computers.

1 is an external view of a loss and theft prevention device of a notebook computer according to an embodiment of the present invention.

1 is a flowchart of a method for preventing the loss and theft of a notebook computer according to an embodiment of the present invention.

The configuration of the present invention to achieve the above object;

A notebook computer having a transmitting means for transmitting the high frequency only to a certain distance;

When the anti-theft function is activated and receives the high-frequency output of the transmission means of the notebook computer and the notebook computer within a certain distance to notify that the standby state, the notebook computer is configured to include a receiver that sounds an alarm when the distance goes out.

The receiver is;

A control means for receiving the high frequency output of the transmitting means of the notebook computer when the anti-theft function is activated and notifying the notebook state if the notebook computer is within a certain distance, and for controlling an alarm to sound when the notebook computer is out of the predetermined distance;

A light emitting diode which emits light by receiving a control signal of the control means;

It is characterized in that it is configured as an alarm device for sounding the alarm by receiving the control signal of the control means.

Another configuration of the present invention to achieve the above object is;

Determining whether an anti-theft function is set;

If the anti-theft function is set, detecting whether a transmission signal comes from the transmitter;

Emitting a light emitting diode when a transmission signal is received from the transmitter;

Generating an alarm sound if a transmission signal does not come from the transmitter;

Checking whether the alarm is released after a predetermined time while generating an alarm sound;

If the alarm has been released, stopping the alarm, or checking again if a signal is coming from the transmitter.

When described with reference to the accompanying drawings the most preferred embodiment which can implement this invention by the above configuration as follows.

1 is a block diagram of an anti-theft and anti-theft device of a notebook computer according to an embodiment of the present invention;

2 is an external view of an anti-theft and anti-theft device of a notebook computer according to an embodiment of the present invention;

3 is a flowchart of a method for preventing the loss and theft of a notebook computer according to an embodiment of the present invention.

As shown in Fig. 1, the configuration of the anti-theft and anti-theft device of a notebook computer according to the embodiment of the present invention;

A first switch connected to the main power source 1 of the notebook computer;

A transmitter (3) connected to the first switch and configured to transmit a high frequency only to a certain distance when the first switch is turned on;

A receiving unit 4 which receives a high frequency output of the transmitting unit 3;

A second switch 8 for turning on / off the anti-theft function;

A controller (5) for judging whether there is a high frequency output by the receiver (8) when the second switch (8) is turned on and performing appropriate control;

An alarm device 9 for receiving an output of the control part 5 and ringing an alarm;

It includes a light emitting diode (6) for receiving the control signal of the control unit to emit light.

Loss and theft prevention device and prevention method of the notebook computer according to an embodiment of the present invention by the above configuration is as follows.

First, when the user needs to move the notebook computer while leaving it, when the first switch 2 and the second switch 8 are turned on, the operation of the anti-theft and anti-theft device of the notebook computer according to the embodiment of the present invention starts. .

When the operation is started, the transmitter 3 receives the main power source 1 through the first switch 2 and generates a high frequency signal which is effective only to a certain distance. Here, the user can arbitrarily set a certain distance.

On the other hand, when the second switch 8 is turned on, the control unit 5 is operated by receiving the auxiliary power source 7, and determines whether the anti-theft function is set (S1). In this case, since the second switch is turned on, it is determined that the anti-theft function is in operation.

Next, the controller 5 detects whether a high frequency signal comes from the transmitter 3 (S2).

At this time, since the transmission signal is coming from the transmitter 3, the controller 5 outputs a control signal to cause the light emitting diode 6 to emit light (S3).

If the user forgets the computer, the distance from the computer is greater than a certain distance, or if the thief runs away from the computer, the transmission signal is not transmitted from the transmitter 3 to the controller 5, so that the controller 5 A control signal for generating an alarm sound is output (S4). At this time, the alarm sound may be a siren or may be replaced with another one.

Next, the controller 5 checks whether the alarm is released after a predetermined time set by the user while generating an alarm sound (S5). If the user is out of a certain distance, it is released by turning off the release switch attached to the alarm device. The release switch may be attached to the alarm device 9, or the second switch 8 may be used in combination.

If the user releases the alarm, the control unit 3 stops the alarm (S6), ie, if the thief steals the computer, the control unit 3 returns to the step S2 of checking whether a signal comes from the transmitting unit (S2). Will be repeated.

In the above process, the main power supply including the transmitter 3 and the first switch 2 are shown in FIG. 2 as the transmitter 21 and the other components are shown in FIG. 2 as the receivers 22 and 23.

As shown in Fig. 2, the receiving device can be in the form of a card 22 or a pen 23, or else.

As described above, in the embodiment of the present invention, by adding a function to prevent theft and loss to the notebook computer, the notebook computer that can prevent the loss and theft by alarming the alarm when a certain distance away from the owner to the notebook computer It can provide a loss and theft prevention device and a prevention method.
