The present invention relates to a controller of a computer, and more particularly, to a controller that can limit the use of a child's computer.

In recent years, computers have gone beyond simple word work or simple one-person games mainly due to the development of the Internet and the spread of high-speed communication networks. The situation is becoming.

However, such an internet can easily find materials and have a good influence on learning. However, children and students are weaker than adults, so once they get into the Internet, they can't break up easily. There is a problem that has a very bad effect on the efficiency of learning.

In addition, if you sit in front of the computer for a long time in such a situation, there is also a problem that impairs vision and health.

Of course, in order to solve this problem, a method of controlling the power supply of the PC power supply or a method of suppressing the use of the keyboard has been proposed. Since the system is not blocked in the long run, there are many problems that can cause the system to fail. In the method of directly controlling the keyboard, the keyboard control program and the program running on the main body of the computer collide with each other, causing frequent downtime. There are many cases where it breaks.

In addition, the method of directly controlling the keyboard may not be able to use it at the time of use due to the control of the use time by date, and if the keyboard is replaced with a commonly used one, the computer may not operate. I have a problem.

Accordingly, the object of the present invention is to provide a computer controller that enables parents to efficiently manage their children's computer use.

Of course, an integrated motherboard is also provided in which sound, video, and LAN functions are integrally formed on the motherboard inside the main body.

In order to output the computational data of the computer to the monitor 10, V, H SYNC (vertical, horizontal synchronization) signal is input from the video card 12 among such peripheral devices and irradiated to the screen of the monitor 10. do.

At this time, the video card 12 and the monitor 10 are connected to the monitor cable (14).

One of the 9-pin and 15-pin monitor cables 14 is selected and used according to the type of the monitor 10.

Hereinafter, a computer use controller according to the present invention will be described with reference to FIGS. 1 to 2.

The video card 12 is connected to one end of the monitor cable 14, the monitor 10 is connected to the other end of the monitor cable 14, and the controller 16 is switched to the middle of the monitor cable 14. The part 18 is connected.

The controller 16 receives and operates the 5V operating power supplied through the video card 12 due to the booting of the computer, and is completely independent of the operation of the central processing unit (CPU) of the computer. It performs a function of controlling the presence or absence of the input of the V, H SYNC (vertical, horizontal synchronization) signal outputted from the video card 12 to the monitor 10.

The controller 16 can operate the monitor 10 only when a separate chip is provided. The controller 16 includes a master chip 19 and a user chip. User Chip) 20.

Each of the master chip 19 and the user chip 20 has a built-in separate memory (EEPROM), which is used by parents to prevent children from using the computer for a long time. ), And the user chip 20 is used by children such as children or students.

In the own memory of the master chip 19 is stored master data that is given the authority to set the use time of the controller 16, the use of the master chip 19 by the master chip 19 in the own memory of the user chip 20 To this end, user data assigned with individual IDs is stored.

The controller 16 will be described in more detail below.

The controller 16 includes a chip insertion unit 22 into which the master chip 19 or the user chip 20 is inserted, a microcontroller 24 performing various operations, and the master chip 20 into the chip insertion unit 22. When inserted into the user chip 20, the key input unit 26 for setting the use time when the user chip 20 is inserted, and the display unit for displaying the set time inputted through the key input unit 26 and its remaining time ( 28), the memory unit 30 for storing data and setting time and remaining time for the master chip 19 and the user chip 20 even when the power is cut off, and the video card (if the use time is exhausted) 12) is composed of a switching unit 18 to block the V, H SYNC (vertical, horizontal synchronization) signal transmitted to the monitor 10 from.

The display unit 28 is formed of any one of a 7-segment, 7 LCD, and a plurality of LEDs to display the use time and the set time.

The key input unit 26 is capable of inputting data in units of hours or minutes, such as an UP-KEY 32 for increasing time and a DOWN key for decreasing time. -KEY) 34, and a SET-KEY 36 for storing the time set in this way in the memory unit 30.

Once power is supplied to the computer main body, V, H SYNC (vertical and horizontal synchronization) signals and DC 5V, the operating power, are input through the video card 12, and the microcontroller 24 operates its own internal memory. If a chip is inserted into the chip insertion section 22, data is received from the chip, and the memory section 30 determines whether the chip is the master chip 19 or the user chip 20. It will be compared with the existing data.

At this time, if the chip of the chip inserting unit 22 is the master chip 19, the microcontroller 24 applies the control signal to the switching unit 18 to turn on the monitor 10 and to the key input unit 26. When the user chip 20 is inserted through) can be set the use time.

If the inserted chip is the user chip 20, the microcontroller 24 displays the usage time on the display unit 28, and the switching unit 18 to turn off the monitor 10 when the usage time limit is exceeded. The monitor 10 is turned off by applying a blocking signal to the.

At this time, the monitor 10 is preferably configured to be switched to the power save mode (POWER SAVE MODE) so that the monitor 10 does not overdo it.

Hereinafter, the control flow of the controller 16 will be described with reference to FIGS. 1 to 3.

When power is applied to the computer main body, V, H SYNC (vertical and horizontal synchronization) signals and operating power are input through the video card 12, and the microcontroller 24 drives its internal memory to operate. Therefore, it is checked whether a chip is inserted into the chip insertion unit 22. (s100)

When the master chip 19 is checked from (s100), the microcontroller 24 inputs the monitor operation signal to the switching unit 18 to turn on the monitor 10, and the key of the controller 16 is pressed. The input unit 26 compares whether there is a key input for time setting.

Of course, at this time, the user can use the computer indefinitely because the monitor 10 is turned on.

If the use time of the user chip 20 is not set from (s102), the master chip 19 is compared with the chip insertion unit 22, and the master chip 19 is not removed. ) Is turned on so that the computer can be used continuously. Once the master chip 19 has been removed from the chip insertion section 22, the microcontroller 24 applies a cutoff signal to the switching section 18 to provide a video card. The monitor 10 is turned off by blocking the V and H SYNC (vertical and horizontal synchronization) signals outputted from the monitor 12 to the monitor 10. (s104).

If there is a use time setting of the user chip 20 from (s102), it is again compared whether or not the master chip 19 is removed from the chip inserting portion 22. If the master chip is not removed, the monitor 10 is ON, so that the computer can be used continuously. (S106)

If the master chip 19 is removed from the chip inserting part 22 from (s106), and the user chip 20 is not inserted in comparison with the user chip 20 being inserted, the microcontroller 24 switches the switching part. A cutoff signal is applied to 18 to turn off the monitor 10 (s108).

When the user chip 20 is inserted from (s108), the user chip 20 is inputted and the user chip 20 is compared with the data stored in the memory unit 30 to determine whether the user is allowed. If the user chip 20 is true, the use time stored in the memory unit 30 is displayed on the display unit 28 to display the use time and the remaining time.

From (s110), the microcontroller 24 compares whether the user chip 20 is continuously inserted into the chip inserting portion 22 and then turns off the monitor.

If the user chip 20 is continuously inserted into the chip inserting portion 22 from (s112), or if the chip is checked as a result of checking the chip from (s100), the microcontroller 24 stores the memory portion 30. In this case, it is compared whether or not the usage time set by the master chip 19 previously stored is exceeded.

At this time, if the use time is exceeded, the microcontroller 24 turns off the monitor 10 by applying a blocking signal to the switching unit 18.

If the use time of the user chip 20 is not exceeded from (s114), since the monitor 10 is continuously turned on, the user can use the computer and the microcontroller 24 continuously checks whether the use time is exhausted. (S116)

Although the embodiments of the present invention have been described in detail as above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiment of the present invention.

As can be seen from the above description, according to the present invention, the parent sets the use time of the computer as the master chip, and the child uses the computer as much as the time set by the parent using the user chip possessed by him, thereby learning. Computers can be used without interruption, allowing parents to manage their children's computer use without friction.

In addition, even if parents go out, it is possible to check how much their children used the computer, so parents can see the outside work with confidence.

In addition, since only the computer monitor is independently operated and controlled independently from the execution program of the computer, there is no problem of conflicting with the program operation of the system, so that the system can be used stably.
