A power switch connecting portion 12 and a main board power switch connecting portion 9 connected to the power switch connecting portion 12 to control the power of the computer main board 11 in the computer power remote control system 1. .

2 is a block diagram illustrating an internal configuration of a computer power remote control system of the present invention.

The operating power of the computer power remote control system 1 according to the present invention is supplied in three ways.

First, when the computer power remote control system (1) is mounted in the motherboard slot of the remote computer 10 to be used, even when the computer 10 is turned off, Power of 3V to 3.3V is supplied through the power supply port 41.

The power supply port 41 outputs the supplied power to the DC voltage amplification circuit 40 and amplifies up to 5V so that the computer power remote control system 1 operates smoothly.

Second, if the computer 10 is powered on by the computer power remote control system 1 or already turned on, power is also supplied through the power supply port 41 of 3V to 3.3V, but 5V power of the PCI slot is supplied. The supply port 36 is also supplied with power to stabilize the operation.

Third, when the model of the computer main board 11 is old and there is no emergency power supply port 41 of 3V to 3.3V, the computer power remote control system 1 of the present invention may operate when the computer 10 is turned off. Power cannot be supplied from outside. At this time, the external power supply is supplied through the adapter jack 21.

The constant voltage circuit 26 stabilizes the voltage applied from the outside through the adapter jack 21 to exactly 5V and then supplies power to the computer power remote control system 1.

The reverse current prevention diodes 27, 34, and 39 may be different in voltage from each of the three methods of supplying power to the computer power remote control system 1. Therefore, the reverse current is prevented from coming back from the voltage difference. Do not cause voltage collisions.

The trunk line connecting jack 24 is connected to a PSTN (telephone line) network to apply a ring (signal) to the telephone line, and the ring detecting unit 32 detects that the ring is applied through the trunk line connecting jack 24 using a photocoupler. The detected ring is converted into digital pulses and transmitted to the microprocessor 42.

 Dial Number Receiving Unit (DTMF Receiving Unit) 31 receives a voice for operation instruction from remote control system 1 through PSTN (telephone line) network. The digital signal is transmitted to the dial number DTMF, which is an analog signal, which is converted into a digital signal and transmitted to the microprocessor 42.

The microprocessor 42 processes the signal received from the ring detection unit 32 to determine the number of rings, and when the number of rings set by the user is reached, forms a LOOP (a state set to receive a call) and then a LOOP (telephone connection). The control relay 28 is operated. When the LOOP control relay 28 is connected, the 600 Ω impedance is formed by the hybrid transformer 29, so that the telephone exchange switches recognize that the telephone line is formed.

After the LOOP is formed, the microprocessor 42 applies an address and a voice output command to the voice IC 30 to control each voice signal so that the user of the computer power remote control system 1 is operating. Tell your voice.

The microprocessor 42 connects or disconnects the power switch relay 37 when the dial number DTMF signal transmitted from the dial number receiver 31 corresponds to a command for turning on or off the computer 10. The user acts as if the user presses the power switch of the computer 10.

That is, the motherboard switch connecting portion 45 is connected to the power switch connecting portion 12 located on the computer motherboard 11, the computer power switch connecting portion 44 is connected to the computer 10 power switch 14, When the power switch relay 37 of the power switch 14 of 10 is connected in parallel, the same operation as the computer power switch 14 is operated.

The memory 43, which is an external data storage device, operates only when the passwords are matched by storing passwords for protecting the user's information, and stores data arbitrarily set by users.

The reset circuit 38 resets the device when the power is unstable to prevent malfunction of the computer power remote control system 1.

The RS-232 connection connector 25 is connected to the RS-232 connection port 13 on the rear of the computer 10 via an RS-232 connection cable to transmit and receive information necessary for operating a general remote control software.

Accordingly, the microprocessor 42 transmits and receives data to and from the computer 10 and the RS-232 IC 33 based on the command transmitted through the dial number DTMF.

3 is an operation flowchart of the computer power remote control system of the present invention.

First, the user makes a call to the remote control system 1 connected to the remote computer to be used (S1).

The telephone signal is applied to the remote control system 1 from the telephone network through the trunk line connecting jack 24, and the ring detecting unit 32 detects the ring signal and inputs it to the microprocessor 42. The microprocessor 42 determines whether the number of rings input from the ring detecting unit 32 is the number of times set by the user. If the set number of times, the microprocessor 42 connects the control relay 28 to the remote user through the telephone connection jack 23. At the same time, the telephone line is connected and the control signal is applied to the voice IC 30 to transmit a message that the telephone is connected (S2).

On the other hand, if the user answers the call and the dial button (# 0 * 0) is pressed before the number of times set by the user, the computer power remote control system 1 forms a LOOP so that the computer power remote control system 1 It is operated in the same state as received (S3).

While the telephone is connected, the microprocessor 42 controls the voice IC 30 to transmit a voice guidance "Please enter a password" to the user (S4).

When the password using the telephone dial is input by the user according to the above instructions, the dial signal is received by the DTMF receiver 31, and then input to the microprocessor 42 to match whether the password entered by the user matches a previously stored password. Make judgment. As a result, if there is a mismatch, the voice IC 30 is controlled to send the user a voice prompt saying "Incorrect input" to the user and returns to the previous step (S4). (S5).

On the other hand, if the password entered by the user is matched, the microprocessor 42 checks whether or not the power of the remote computer 10 (S6).

As a result, when the computer 10 is turned off, the microprocessor 42 controls the voice IC 30 to send a voice prompt, "Press the star button to turn on the PC." Send to the remote user via the telephone line connected to (S7).

At this time, when the user presses a button other than the star button, the microprocessor 42 controls the voice IC 30 to send a voice announcement saying “incorrectly input” to the user through the telephone line and to perform the previous step (S7). Return to (S8).

On the other hand, when the user presses the star button and the computer 10 is not powered on, the microcomputer 42 controls the voice IC 30 to control the voice IC 30 and the voice button "PC power is not turned on" again with the star button. Return to the previous step S7 to press.

On the other hand, when the user presses the star button and the computer is turned on, the microprocessor 42 controls the voice IC 30 so that the user can enter the voice message of the next step through the telephone line. Send to (S9).

When the microprocessor 42 determines that the user has pressed the star button for inputting the guest IP, the microprocessor 42 controls the voice IC 30 to send the voice message to the user by controlling the voice IC 30. If the entered guest IP is wrong, the voice IC 30 controls the voice announcement "Incorrect input" and the voice announcement "Enter the guest IP" again to the user (S10).

Thereafter, the microprocessor 42 checks the user IP input by the user and inputs a voice prompt saying "The guest IP input is xxx.xxx.xxx.xxx. If it is correct, press the asterisk and press the well sperm to enter again." When the voice IC 30 is controlled and sent to the user and the well sperm is pressed, the process returns to the previous step S10 (S11).

If it is determined that the microprocessor 42 matches the guest IP, the microprocessor 42 controls the voice IC 30 to send the voice announcement to the user by controlling the voice IC 30, which is the last step. When the computer is able to work on a remote site, the control relay 28 is blocked to terminate the telephone connection (S12).

On the other hand, if it is determined in step S6 that the power of the computer 10 is already on, it is determined whether the computer 10 connected to the computer power remote control system of the present invention is driven (S13).

If the microprocessor 42 determines that the power of the computer 10 is still booting (when the communication with the computer power remote control system 1 does not occur within three minutes after the power is turned on), the "PC is not yet running" The voice announcement is controlled by the voice IC 30 to be sent to the user and the control relay 28 is cut off to terminate the telephone connection.

If the microprocessor 42 determines that the computer 10 connected to the computer-powered remote control system 1 of the present invention cannot be driven within 3 minutes, " Please press the asterisk for the guest IP input and the well sperm for turning off the PC. &Quot; And transmits the voice announcement to the user by controlling the voice IC 30, and when the user presses the star button, the user inputs an IP according to the voice announcement in steps S10 to S12 and connects with the computer 10 to be used. The voice IC 30 is controlled to inform the user, and when the user presses the well sperm, the computer is terminated in the set path (S14).

At this time, when the user presses the well sperm button to shut down the computer, the computer 10 connected to the computer power remote control system 1 of the present invention is no longer driven, whereas the program is set to shut down using software. Even if the well button is pressed, the computer 10 is not terminated.

On the other hand, when the microprocessor 42 is determined to be driven by the computer 10 connected to the computer power remote control system 1 of the present invention, "The host IP is xxx.xxx.xxx.xxx. Press the star to turn off the PC and press the star to enter the guest IP "voice control message to the IC (30) is sent to the user, if the user presses the well button, the computer is shut down in the set path If you press the zero button, repeat this step (S15) once again, and if you press the star button, enter the IP according to the voice guidance of steps S10-12 to be connected to the computer 10 to use the voice The IC 30 is controlled and sent to the user.

In addition, when it is determined that the user presses a button other than the designated button, the microprocessor 42 reads the message "You have entered the wrong number" and "Enter again the number, Turn off the PC, and enter the guest IP." Press the asterisk " " to control the voice IC 30 and send it to the user (S15).

The microprocessor 42 controls the voice IC 30 to control the voice IC 30, “If the input time has been exceeded,” when the dial is not pressed for 7 seconds after every voice announcement or when the dial is not pressed within 10 seconds. The control relay 28 is cut off at the same time as the call is sent to the terminal to terminate the telephone connection.

On the other hand, even if the person who answers the phone hangs up the handset, the call state is maintained because the computer power remote control system 1 forms a LOOP.

As described above, according to the computer power remote control system according to the present invention has a number of excellent effects as follows.

First, it maximized the compatibility of computer models with different manufacturers using RS-232 communication to prevent collisions between operating systems.

Second, there is no fear of being exposed to others by entering IP and password.

Third, anyone can easily use the remote computer control while listening to the voice guidance.

Fourth, it is possible to remotely control the computer power regardless of the power state (ON / OFF) of the computer to be controlled.
