Description

The control equipment for computer monitor by DDC (display data channel) signal controlling}

The present invention relates to a computer-use control device, and in particular, a microcomputer is embedded and a keypad for inputting a command to the microcomputer, and a display window for displaying a control signal or a keypad input signal of the microcomputer are input. Time control The present invention relates to a device capable of controlling computer use by making a screen of a monitor difficult to recognize by controlling a signal between the monitor and a computer through the monitor socket according to a time control command.

The monitor socket is a socket to which a cable with a connector for transmitting a signal between the monitor and the computer can be connected. Generally, the signaling method between the monitor and the computer is called a display data channel (DDC) signal method. Signal compatibility between producers and computer manufacturers. As a low standard global signal system, data information between the monitor and the computer is transmitted through the DC signal connector.

Existing general control devices are built in the main body of the product to automatically cut off the power according to the time control method, or to cut the signal according to the time control through a microcomputer or a timer in the signal connection socket.

In recent years, due to the rapid increase in the spread of computers, the age of computer use is exceeding age from young children to adults. Especially, the Internet using computer has reached ten million people.

However, the side effects of this are not so severe that the Internet addiction caused by the use of the Internet has reached a serious level and is becoming a social problem.

Internet addiction is a symptom of "tolerance symptoms" that can lead to self-satisfaction with the use of the Internet for a long time, and symptoms such as anxiety, anxiety, or compulsive thinking or fantasy (or daydreaming) about the Internet. "Prohibition of symptoms" and the occurrence of social, occupational, and abandonment activities that are important for Internet use.

The attractiveness of the Internet is strong enough to be addicted to it, and its power destroys everyday life and becomes a social problem.

In fact, Internet addiction causes family breakdown due to the unrealistic relationship of virtual space, and uncontrollable desire for use causes academic problems, and various problems occur in the work life due to excessive use of internet after working hours and working hours. The current reality is that even after retirement, it spread to all areas of home and society, harming not only you but also those around you.

In particular, parents who raise their children in the home are not concerned about the fact that their study time is secured by the Internet, and they are struggling to prepare for such measures. The reality is that there are many parts that must be submitted by searching through the computer and the Internet.

In other words, the phenomenon of addiction caused by the use of the Internet is becoming a more serious social problem among adolescent students whose academic habits are beginning to become fixed.

However, in the case of the conventional computer and the Internet, the problem is that there is no way for parents or themselves to restrict their use and supervise their management. I'm leaving without.

The above-mentioned conventional control devices can be used to manage computer usage time, remove peripherals (mouse or keyboard), and enter passwords.However, this can prevent the use of computers required for internet learning or office purposes, Blocking causes a bad sector on the hard disk of the computer, thereby degrading the performance of the computer.

The present invention has been made in order to solve the above-mentioned problems, if you set the available time and input the signal between the computer and the monitor automatically connects the microcomputer automatically maintains the monitor screen, other time is It aims to prevent the user from using the computer by making the screen of the monitor difficult to recognize by the microcomputer automatically blocking the signal between the monitors.

In order to achieve the above object, the present invention forms a keypad for inputting information, a display unit for displaying the input information, and a socket into which the monitor cable is inserted, and the lock device is inserted into the housing so that the monitor cable inserted into the socket cannot be removed. A microprocessor unit configured to generate a signal capable of controlling a connection time of a signal transmitted through the monitor cable according to a housing unit attached to the housing unit and a time control command input from the keypad; A relay for each signal connected to the socket to be inserted is turned on and off by a control signal generated by the microprocessor, a relay for connecting the signal to the other contact point of the relay for each signal, and a monitor connection socket mounted on a computer; Consisting of a cable part with a connector to which it can be connected The technical gist of the device is to control the use of the computer by controlling the monitor signal.

1 is an internal circuit block diagram of a control device according to the present invention, and FIG. 2 is an external view of the control device according to the present invention.

As shown in FIG. 1, the present invention includes a microprocessor 100 for processing information and a display window 110 in which predetermined information is displayed by a control signal of the microprocessor 100, and the microprocessor 100. Keypad 120 for inputting information and a socket 210 into which the monitor cable 210-A can be inserted, and a cable 210-B with a connector connecting the computer and the control device.

The microprocessor 100 of FIG. 1 generates a control signal according to the set time control command.

The time control signal is connected to the monitor cable 210-A and the cable 210-B to which the connector is connected through the relay 200 connected to the microprocessor 100 to turn on and off the signal between the monitor and the computer. To control the time.

The microprocessor 100 allows information input through the keypad 120 and other guide information to be displayed through the display window 110 for efficient input of time control commands, and the like for the strict management of time control. Information also has a function to manage input.

In the use of the present invention, the monitor cable 210-A is coupled to the socket 210 attached to the control device, and then the connector attached cable 210-B is coupled to the monitor connection socket of the computer.

And after the user sets the use time and password through the keypad 120 of the control device to operate the lock device (2) so that the enclosure (1) does not open.

Since the time control is set once and repeatedly turned on and off according to the setting time, the time control is continuously operated unless the user changes the setting, and the control information recorded in the microprocessor 100 is not damaged in case of power failure, Automatically cuts off the signal between the monitor and the computer when no power is applied.

According to the present invention described above, there is an advantage that effective computer control is possible because the computer can not be used to make the screen of the monitor difficult to recognize the signal between the monitor and the computer.
