After 3 times of ringing by the phone, if the control control unit 100 succeeds in answering the call, a success sound such as 'Ding dong den' or a success signal such as a lamp display and vibration, and the user fails to answer the call It proceeds to the previous stage while generating a beep sound such as a signal or a failure signal such as a lamp display and a vibration.

Subsequently, if the password is correct, a success signal as described above is generated, and a failure signal is generated.

Thereafter, the step of turning on / off any one or all of the remote computer 300.

If the success by the on, off, the success signal as described above, if the wrong signal is generated, it is possible to try again indefinitely immediately. At this time, whether the command of the remote control board is successful or not is immediately distinguished by analyzing the signal from the user PC equipped with the management robot.The remote PC reports the booting result to the relay server after booting. The value is known.

In addition, the present invention is to turn on the power of the remote computer 300, when the line is abnormal, the control control unit 100 is basically self-recovery, in this process the control control unit 100 starts to operate the power Rough

After that, the control and control server 202 goes through a check and self-report.

Subsequently, the control and control unit server 202 is checked and asked if it is attempted for 3 minutes.

In the step of asking for 3 minutes, if yes, periodically log to the control and control server server 202 and leave a unique number and self-approved IP, if no, the modem 103, the router 104 After ON / OFF, after 10 seconds, the control control unit 100 is turned on / off and then the control control unit 100 goes back to the power start step.

Finally, the step of controlling the computer screen of the remote computer 300 applied to the present invention is as shown in FIG.

First, the remote computer 300 is booted and loaded.

Thereafter, the step of communicating with the designated control control unit 100.

Subsequently, the location of the user computer 400 is determined.

After that, the direct communication with the user computer 400 is performed.

If the communication step is successful, the remote computer 300 goes through a step of asking the user of a predetermined time of acceptance / denial. If there is no intention of accepting / rejecting for a certain period of time, automatically accept (specify the setting value at installation).

Subsequently, in case of 'accept', the screen remote control starts and ends by the user computer 400, and in case of 'reject', the request message is output and the process is automatically terminated after waiting for a predetermined time.

On the other hand, the manager computer 500 stops the control unit 100 when a stop command is issued from the server 200 when the monthly fee (ASP) is not paid, and reports again from the beginning when the power is reset, and can be used by the server 200. If it is allowed to continue to use, the server 200 has a stop command and stops. That is, if the control control unit 100 is continuously connected to the state that the monthly fee is not paid, the server 200 is asked whether or not it can be used once every time the power of the control control unit 100 is reset.
