Description

Anti-theft device and method thereof of notebook computer

The present invention relates to an anti-theft device and method of the notebook computer, and more particularly, to an anti-theft device and method of the notebook computer capable of preventing theft by outputting an alarm sound in accordance with the change of position.

Recently, with the development of computer manufacturing technology, miniaturization and light weight have become possible, and accordingly, the spread of portable computer systems, that is, notebook computers, has increased. As the popularity of the notebook computer increases, a lot of loss and theft accidents occur, and data stored in the computer is also lost at the same time, thereby causing many problems.

Due to the above reasons, research into adding a function for preventing theft to a notebook computer continues.

In the prior art, in order to prevent theft, as shown in Fig. 1, a Kensington locking device is installed on one side of the notebook computer (see A of Fig. 1), and if necessary, a separate hook is attached to this part. To prevent theft. At this time, one side of the ring is fixed to the notebook computer, the other side is fixed to the desk or the like.

However, in the conventional technology as described above, there is a problem that the user has to always prepare the ring and carry it around, and even when the user is temporarily away from the user, there is a problem that cumbersome work such as connecting the ring is required.

In addition, there is a problem that it is difficult to prevent theft because the user does not know the theft quickly because there was no function to inform the user when there is no user.

The present invention has been made to solve the above problems, the object of the notebook computer is provided with a semiconductor pressure sensor to determine the movement of the notebook computer and to prevent theft by generating an alarm sound when moving. An anti-theft device and a method thereof are provided.

Another object of the present invention is to provide an anti-theft device and method for preventing theft of a notebook computer by transmitting a message to a user's wireless pager or a cordless phone through a modem embedded in the notebook computer when theft occurs. To provide.

1 is a view for explaining the anti-theft method according to the prior art,

Figure 2 is a block diagram showing the configuration of an anti-theft device according to the present invention.

30: control unit 40: message output unit

50: modem

According to a first aspect of the present invention for achieving the above object, a mode setting unit for determining whether to perform an anti-theft operation to be operated by the user, and is mounted to the bottom of the notebook computer by the mode setting unit The anti-theft device of a notebook computer including a sensor unit for detecting whether the system is lifted when the anti-theft mode is set, and a message output unit for outputting a message informing of theft when the system is detected by the sensor unit. to provide.

In this case, according to an additional feature of the present invention, when the message is output from the message output unit, it is preferable to further include a modem for notifying the occurrence of theft by transferring the message to the user's pager or wireless telephone.

In addition, according to a second aspect of the present invention for achieving the above object, a first step of the user setting the anti-theft mode; A second step of detecting whether the system is lifted and driving the control program when theft is detected; A third step of connecting to a communication device possessed by a user through a modem mounted in the system; And a fourth step of transmitting a theft signal to the communication device of the third step to notify the user of the occurrence of theft.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

2 is a block diagram showing the configuration of an anti-theft device for a notebook computer according to the present invention.

2, reference numeral 10 denotes a semiconductor pressure sensor mounted at the bottom of the notebook computer. The semiconductor pressure sensor 10 is applied to a pressure corresponding to the weight of the notebook computer when the notebook computer is installed on the desk so that the notebook computer can be used, and when the theft occurs, the notebook computer is lifted up. The pressure applied to the vehicle is reduced, and it detects theft and determines theft.

Also, reference numeral 20 denotes an anti-theft mode setting key for determining whether the anti-theft device to perform an operation or stop. When the user lifts the system for movement, the anti-theft device according to the present invention should be prevented from operating so that the keyboard portion of the notebook computer is provided as a separate button so that the user can determine the operation with a simple operation. Do.

In addition, reference numeral 30 denotes a controller for determining whether to output a message notifying the occurrence of theft according to the states of the semiconductor pressure sensor 10 and the anti-theft mode setting key 20, and 40 denotes the controller 30. The message output unit outputs the theft generation message in accordance with the control signal of. In this case, the theft generation output unit 40 may output an alarm sound or output a voice signal such as "do not move the computer".

In addition, reference numeral 50 denotes a modem capable of transferring a message by being connected to a communication device such as a pager or a wireless telephone of a user according to a control signal of the controller 30 when theft occurs.

Referring to the operation of the present invention having the configuration as described above are as follows.

First, when the user wants to empty the seat for a while, pressing the anti-theft mode setting key 20, the system performs the anti-theft function. At this time, a pressure corresponding to the weight of the notebook computer is applied to the semiconductor pressure sensor 10. When the notebook computer is lifted due to theft, the pressure applied to the semiconductor pressure sensor 10 decreases abruptly.

On the other hand, the controller 30 continuously monitors the pressure detected by the semiconductor pressure sensor 20, and if the pressure suddenly decreases, the controller 30 detects it and determines theft. At this time, if theft is detected, the controller 30 outputs a control signal to the message output unit 40 to output an alarm sound or a voice signal, and simultaneously outputs a control signal to the modem 50 to the user. The message is transmitted to a communication device such as a pager or a wireless telephone.

The modem 50 drives a separate program to dial a user's communication device, and transmits a message when a connection is made. The message is a "stolen alarm" stored in text form. Or use a prearranged number and signal.

The user who has received such a message can quickly move to the location where the notebook computer is located, thereby preventing theft.

On the other hand, when the notebook computer is in the power-off (off) state, the anti-theft mode is on (on) to support the minimum power to the semiconductor pressure sensor 20, by turning on the computer (on) when theft is detected Performs the operation of.

The anti-theft device and method of the notebook computer of the present invention as described above can reduce the theft by generating an alarm sound or a voice signal when the system is moved, and promptly notify the user to move to the position of the system To prevent theft.
