The present invention relates to a portable notebook, and more particularly, to a portable notebook and an anti-theft method having an anti-theft function that can prevent theft of the portable notebook.

In general, most of the anti-theft methods for laptops ignore the economics and practicality, and only present the idea of 'doing it this way'.

In particular, in the prior art, in order to prevent theft, a Kensington locking device is installed on one side of the notebook computer, and when necessary, a separate hook is connected 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 such a technique, the inconvenience that the user always has to prepare and carry the ring occurs, even if the user is temporarily away from the need for cumbersome work such as connection of the ring has a problem that is difficult to move quickly. In addition, there is also 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 theft without the user.

In addition, since these chains are cut off, they are not easy to dismantle, and they are mostly used only in large demand stores such as laptop booths. In addition, if you do not have a place to hang the chain when using outdoors, some users may be reluctant for aesthetic reasons.

      Since the chain type has to occupy a certain amount of volume and its performance is heavier as it is heavy, it has been a problem that it is inconsistent with the convenience of notebook users who focus on mobility.

In addition, in order to prevent theft of the notebook, in the case of theft, the notebook detects the vibration of the notebook and when the notebook vibrates, an alarm is generated and an alarm is issued to the surrounding people. Even when the vibration caused by work or the like does not correlate with the theft of the notebook, the alarm caused by the vibration occurs, the use is inconvenient, and there is a problem that the practicality is deteriorated accordingly. In addition, such a vibration sensor type has a disadvantage that the sensing technology of the sensor part is usually uneconomical because it often uses an expensive vibration sensor or gyroscope.

The present invention has been made in view of the above circumstances, and the object of the present invention is that if someone tries to steal the notebook PC, the portable notebook screen can be closed to create a minimal volume and put it in its own bag, etc. With the screen open, the portable notebook is not easy to move, so when the user is away and the system is running, the sensing module detects the movement of the portable laptop screen and when the other person tries to steal the laptop screen The present invention provides a portable notebook and an anti-theft method with an anti-theft function that can emit an alarm sound when the door is closed.

A power module for supplying power to each device of the portable notebook; And

And a control module configured to receive the detection signal to generate an alarm signal or to supply power from a predetermined battery when the power supply line of the power module is cut off to generate the alarm signal.

Anti-theft method in a portable notebook according to a second aspect of the present invention for achieving the above object,

a) operating the anti-theft detection system by selecting an anti-theft start button provided in the portable notebook;

b) detecting the movement of the portable notebook; And

c) generating an alarm signal when the movement of the portable notebook is detected.

Preferably, the anti-theft method in the portable notebook,

When the power button is pressed during the theft detection system operation, the power button is not operated or the alarm sound is further generated.

More preferably,

When the portable notebook is discharged while the theft detection system is in operation and the portable notebook is rebooted, the notebook theft system is operated on the screen of the portable notebook by dual operation in the BIOS Setup step and the OS startup step. Displaying a password input window;

If the password entered through the password input window is a password set by a user, terminating the program for preventing theft; And

The method may further include generating an alarm sound when a password input through the password input window is an error of a predetermined number or more.

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

1 is a block diagram of a portable notebook computer having an anti-theft function according to an embodiment of the present invention, and FIG. 2 is a schematic internal block diagram of FIG. 1.

Referring to FIG. 1, when a sensor 140 is provided between a screen and a keyboard of the portable notebook 100 to cover the screen in the direction of the keyboard, the sensor 140 generates a detection signal. An example of the sensor 140 includes a light receiving / light emitting device, a reflective photointerrupter, a transmissive photointerrupter, and the like, which are infrared sensors. In addition, it is also possible to use a variable resistor as the sensor 140.

The sensor 140 generates an alarm signal when the signal of the portable notebook screen is different from the state in which the anti-theft system is driven, and the generated alarm signal is not turned off until a password is input by the user. Therefore, when the detection signal is generated by the sensor 140, an alarm signal is output by the detection signal to inform that the portable knob book is stolen.

In addition, when the system is operated, at the same time, when the light emitting diode (LED) 120 does not cover the screen of the portable notebook 100 to start blinking, it is possible for others to know that they are in theft situation.

In addition, when the notebook is turned off due to various reasons while the sensing module is turned on and the sensing module is turned on, the notebook or the power cord may be recharged to recharge the battery. When rebooting, the portable notebook's system does not go to the operating system, but a password prompt is displayed immediately to allow the portable notebook to continue booting if the password is entered correctly, or the password is immediately displayed on the first screen even if the OS (windows, etc.) is operating. The input window is displayed so that the portable notebook can be operated when the password is correctly entered.

In other words, when the portable notebook is rebooted, the notebook theft system is operated in the BIOS Setup step and the OS startup step so that a password input window is displayed on the screen of the portable notebook.

Therefore, even when the hard disk of the portable notebook is formatted or replaced with another hard disk, the burglar alarm system operates in the CMOS area so that the portable notebook can be used only when the correct password is input to the portable notebook.

2, the portable notebook includes a sensing module 210, a power module 230, a control module 250, and an output module 270.

The sensing module 210 is connected to the sensor 140 of FIG. 1 to detect whether the screen of the portable notebook 200 moves in the direction of the keyboard or whether the screen of the portable notebook 200 is moved to control a detection signal. Provided as a module.

The power module 230 supplies power to each device of the portable notebook 200 as a battery attached to the portable notebook 200 or a power supplied from the outside.

The control module 250 receives the detection signal from the sensing module 210 to generate an alarm signal, or generates the alarm signal when the power supply line of the power module 230 is cut off. In other words, when the battery or power line of the notebook is detached by someone, an alarm is generated when the RTC (Real Time Clock) battery is powered.

The portable notebook 200 further includes a built-in speaker (not shown) to output the alarm signal as a sound.

In one application, the portable notebook 200 is equipped with an LED in a predetermined position of the portable notebook to display the alarm signal, in which the LED flashes the light to display the alarm signal. The LED starts operation when the anti-theft system according to the present invention is turned on, and the LED is turned off when the portable notebook 200 is turned off.

The operating state of the present invention configured as described above will be described.

3 is a flowchart illustrating a method of realizing an anti-theft function in a portable notebook according to an embodiment of the present invention.

When the anti-theft start button provided in the portable notebook is selected, the anti-theft system implemented in the portable notebook operates, and the screen saver is driven after a predetermined time elapses (S300 and S310). In addition, due to the operation of the anti-theft system, the portable notebook detects movement by using a sensor attached to a predetermined position and causes the LED mounted at the predetermined position of the portable notebook to be damped (S320).

In this case, the anti-theft system generates an alarm signal when the movement of the portable notebook is detected. An example of the movement of the portable notebook is that the screen of the portable notebook is covered in the direction of the keyboard or the battery of the portable notebook is removed. Or when the power supply from the power cord connected to the portable notebook is cut off.

In addition, when the power button is pressed during the theft detection system operation, the power button does not operate or the alarm sounds.

As described above, when detecting the movement of the portable notebook, the alarm signal is generated (S380).

When a predetermined time elapses after the anti-theft start button is selected in the portable notebook, a screen saver is driven on the screen. When one of the keypads of the portable notebook is selected, a password input window is displayed (S340 and S350).

The anti-theft system implemented in the portable notebook generates an alarm when the password input through the password input window is an error more than a predetermined number of times (S360). However, the alarm sound is implemented to be released when the password is set by the user.

When the password input in the password input window in step S360 is correct by the user-set password, the portable notebook switches the anti-theft system to the standby state to detect the movement state of the portable notebook (S370).

In one application, when the password is an error more than a predetermined number of times, not only an alarm but also an LED attached to one side of the portable notebook is implemented to blink, and the blinking of the LED is only OFF when the password is input. To be designed.

As described above in detail, according to the portable notebook and the anti-theft method with an anti-theft function of the present invention, since the system is implemented inside the portable notebook, there is no need to purchase and install equipment for theft prevention separately By selecting one shortcut key on the system, theft system can be driven, thereby providing convenience for the user.

In addition, it is possible to implement an anti-theft system by using the devices of the portable notebook already built, without the need to embed additional devices such as a speaker or a power source in the portable notebook to implement the system of the present invention, in particular the battery If is missing, the alarm sound can be issued using the RTC battery.
