Hereinafter, an example of using the multi-function Internet cutoff controller according to the present invention will be described.

First, in order to use the multi-function internet cutoff controller 100 according to the present invention, first and second communication are performed on the first and second connection outlets 120 and 130 exposed on the back of the main body 110 of the multi-function internet cutoff controller 100. By connecting the cable plugs 40 and 50, the computer 30, the modem 10, or the router 20 are connected, and a power cable is connected to the power connection outlet 190.

In addition, when the multi-function Internet blocking controller 100 is operated for the first time, the power button 171 is pressed and initialized.

In this state, the initial operation and password can be changed. In this case, a basic password (for example, '1234') provided for the first time is inputted by pressing the number button 172, and the completion button 173 is pressed, and then the password change button 175 is pressed again. Then, enter a new password (for example, '0506') and press the completion button 173 to set a new password. Of course, the password is naturally stored in the memory 162 of the control panel 160.

And, if you want to change the password, enter the current password (for example, '0506') by pressing the number button 172, press the password change button 175, and then change the password (for example, '0510' can be set by pressing the number button 172 and then pressing the completion button 173.

On the other hand, by displaying the display unit 180 every time a button operation of the key input unit 170 for the above password setting can be set while the controller checks this.

Hereinafter, a process of setting internet usage time will be described.

The Internet use time can be set in two ways: real time setting (specific time zone setting available for the Internet) and the designated time setting (total time available for Internet use per day).

First, the real-time setting method (setting of a specific time zone that can be used on the Internet) may allow, for example, to use the Internet once or five times a day according to the controller's judgment. Can be changed). This is when the controller presses the number button 172 to input the password and presses the completion button 173, then presses the real time button 176, presses the number button 172 '0' and presses the completion button 173. The default input is cleared in sequence and initialized. Then, press the number button 172 '1' (indicates the order of setting the first usage time), and if the usage time is allowed from 6:30 am to 10:30, the number button 172 is pressed. Press '6302230' and then press the Done button 173 to set the real time (that is, the specific time zone available for the Internet), and can be set several times.

In this case, the Internet can be used only at a corresponding time (ie, '6:30' to '22: 30 '). After setting in this way, press the power button 171 to turn it off, and press the power button 171 again to turn it on to operate normally as set.

Therefore, when the set time elapses, the control panel 160 operates the opening and closing means 152 to block the communication line 150 to block the Internet.

Next, the Set Time (Total Days Available for Internet) setting allows the controller to freely allow or restrict the time spent on the Internet within the range of 24 hours per day, for example, using only 1 hour and 35 minutes per 24 hours a day. In the case of allowing 1 hour and 35 minutes, the control panel 160 operates the opening and closing means 152 to block the communication line 150 to block the Internet.

In this case, the set number of times is set once, and the number of resets is preferably unlimited. In addition, an Internet user can freely access and use the Internet within a designated time (for example, 1 hour 35 minutes) regardless of the number of times of Internet access.

That is, the controller presses the number button 172, enters the password, presses the completion button 173, presses the designated time button 177, presses the number button 172, for example, and then presses '135'. Press the completion button 173, press the power button 172 to turn off and press the power button 171 again to turn on and operate as normal.

In this case, when using the Internet, the user must press the start button 178a, then use the Internet, and after the use is finished, press the end button 178b to check the usage time. That is, it does not operate unless the start button 178a is pressed, and all of the available time is extinguished unless the end button 178b is pressed.

On the other hand, if you want to change the time in addition (for example, if you want to modify '7:21 AM' to 8:11 AM), the controller enters the password by pressing the number button 172, the completion button 172 After pressing), after pressing the current time correction button 179, press the number button to enter '0811', and press the completion button (173) to set.

By setting the Internet use time in the above manner, and after the set time elapses, the communication line 150 is completely blocked, thereby preventing inadvertent use of the Internet and effectively blocking and controlling the Internet.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the scope of the present invention to be substantially equivalent to the embodiment of the present invention. Various modifications can be made by those skilled in the art without departing from the scope of the present invention.
