2. Description of the Related Art As described in H05165553, a system which has a computer interface, a modem detects a signal from a communication network, and turns on the power of a connected device has been used in the information device market. Has been used in the center. However, in such conventional technology, not only does the system have a password confirmation function, but also the system responds to access such as a wrong telephone, or the system is damaged by allowing unauthorized access from the outside. It could lead to inconvenient results.

[0003] Further, in such a conventional technique, although the power can be turned on to a connected device, there is no function to turn off the power.
There was a possibility that the power company would charge a high electricity rate at a later date.

[0004]

In these prior arts, the access provided via the communication network is:
Many inconveniences have been induced due to the inability to obtain authentication as to whether the range is within the range approved by the parties and the fact that the system itself does not have the function of turning off the power. The present invention has been made in view of the above-mentioned problems of the prior art, and aims to solve the problems by incorporating a user confirmation function using a password and a power-off function, thereby improving the reliability of the system.

[0005]

To achieve the above object, a remote power supply system according to the present invention is characterized in that the remote power supply system has a user confirmation function using a password.

Further, the remote power supply system of the present invention has a computer interface, sends a shutdown signal to the computer interface based on a preset procedure or a procedure transmitted from a partner terminal, and then supplies the power supply outlet. Characterized in that the power supply is turned off.

[0007]

As described above, the remote power supply system of the present invention has a user confirmation function using a password, thereby preventing malfunction of the system due to a wrong telephone call and maintaining security.

Further, the remote power supply system of the present invention has a computer interface, sends a shutdown signal to the computer interface based on a preset procedure or a procedure transmitted from the partner terminal, and then supplies the power supply outlet. By turning off the power supply, it is possible to prevent forgetting to turn off the power supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a remote power supply system according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a block diagram of a remote power supply system of the present invention. With reference to FIG. 1, blocks constituting the outside and the inside will be described. Outside the remote power supply system 1, a communication line interface unit 2 for connecting to a communication network, a computer interface unit 3 for connecting to a computer, and a power supply interface for connecting to an external device requiring power control The unit 4 has three external interfaces.

In the remote power supply system 1, a communication line control unit 7 for detecting a signal from a communication network through a communication line interface unit 2 and a password input from a user through the communication network. Has a password signal detecting unit 8. The password signal detected by the password signal detector 8 is passed to the processor 5 through the system bus 11 and is compared with the password recorded in the memory 6.

The computer communication control unit 9 transmits a shutdown signal to the computer through the computer interface unit 3 before the power supply outlet is turned off according to a preset procedure.

Further, there is provided a power control unit 9 connected to the power interface unit 4 for supplying power to an external device requiring power control.

The communication line control section 7, password signal detection section 8, computer communication control section 9, power supply control section 10, processor 5, and memory 6 in the remote power supply system 1 described above are connected by a system bus 11. . The connection between each control unit and each interface unit that is paired with each other is connected by a dedicated bus 12. The external and internal configurations of the remote power supply relating to the remote power supply system of the present invention have the above-described configurations.

FIG. 2 shows a system configuration diagram of the remote power supply system of the present invention. The configuration of the system will be described with reference to FIG. FIG. 2 shows a system configuration of a minimum unit for expressing the features of the present invention. Remote power system 1
Is connected to a computer 17 via a computer communication cable 16 connected to the computer interface unit 3. The computer 17 connects the power cable 18 of the computer 17 to the power interface unit 4 of the remote power system 1 and can receive power from the remote power system 1.

The remote power supply system 1 is in a state where it can communicate with a communication device 13 connected to the communication line 15 via a communication line 15 connected to the communication line interface unit 2 and a communication network 14. .

Next, the operation of the entire system will be described with reference to FIG. Before starting the description, it is assumed that the remote power supply system 1 does not supply power to the computer 17.

The remote power supply system 1 called from the communication device 13 via the communication network 14 requests the communication device 13 to transmit a password. The password is transmitted from the communication device 13 in accordance with the password transmission request. The remote power supply system 1 checks whether the received password is correct or not according to the method described above. If the password is incorrect, the communication line interface unit 2 is closed and communication is cut off. When the password is correct, the communication with the communication device 13 is continued.

During continuous communication, the communication device 13
Received a power-on instruction from the
The remote power supply system 1 supplies power to the power supply interface unit 4. As a result, the computer 17 is activated.

Thereafter, if the user forgets to turn off the power of the computer 17, the remote power supply system 1
Has a preset power-off procedure, so that after sending a shutdown signal to the computer 17 via the computer interface 3, the power supplied to the power interface 4 is cut off. As a result, after the computer 17 ends normally, the power is turned off. Here, it has been described that the computer is connected to the power supply interface unit. However, it is needless to say that the power supply can be controlled according to the above-described procedure even for other electric devices.

[0020]

Since the present invention is configured as described above, it has the following effects.

By having a user confirmation function using a password, it is possible to prevent malfunction of the system due to a wrong telephone call or the like, thereby improving the reliability of the system.

A computer interface,
By sending a shutdown signal to the computer interface based on a preset procedure or a procedure transmitted from the partner terminal, and then turning off the power supply outlet, it is possible to prevent forgetting to turn off the power.
