DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a power supply device, an automatic power supply control device, and a central processing unit that receives power supply from the power supply device.

An information processing system is provided with a remote terminal A, and an automatic power supply control device sends out a power supply disconnection signal in accordance with a power disconnection command from the remote terminal, and a line procedure control means and a line switching means are provided. The line switching means switches the connection of the remote terminal line to the line procedure control means according to the power cutoff signal sent in accordance with the power cutoff command from the line switching means, and the line procedure control means checks whether or not the power supply device is disconnected. A signal or message corresponding to the result is transmitted to the remote terminal via the line switching means, and when a turn-on command is issued from the remote terminal, the line control means sends a power-on instruction to the automatic power supply control means. According to this power-on instruction, the automatic power supply control device sends a power-on signal to the power supply device and the line switching means to activate the line switching means, and connects the remote terminal to the central processing unit, thereby connecting the remote terminal to the central processing unit. The power supply of the calculation center can be automatically turned on and off by operating the terminal.

[Industrial application field]

The present invention relates to a remote control method for a power supply device of a calculation center, which enables the power supply of the calculation center to be automatically turned on, turned off, and confirmed by a command from a remote terminal at a remote location.

[Conventional technology]

Even if a user attempts to check the status of the center from a terminal connected to the IVl calculation center, he or she can only find out whether or not the terminal is connected to the application program. Therefore, although it is now possible to turn off the power to the center from the terminal side, it was not possible to determine whether or not the power to the center was reliably turned off.

Therefore, when disconnecting the power to an unmanned center using software from a remote location, contact the center's security personnel to ensure that the power and air conditioning are turned off. I needed to confirm that it was installed.

In addition, although it was possible to automatically turn on the power to the center using a preset calendar timer, it was impossible to turn on the power to the center from a remote location at a time different from the time set above. Met.

Therefore, if it is desired to change the scheduled power-on time, the center staff has to manually turn on the power or change the settings of the calendar timer.

[Problem that the invention seeks to solve]

Due to these circumstances, we have taken the time to unmanned the operation of the calculation center,
Even if efforts were made to save labor, it would be difficult to completely eliminate the need for human labor.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to confirm power-on and power-off of a center from a remote location, thereby promoting unmanned operation and labor-saving of the center operation and management.

[Means for solving problems]

As shown in FIG. 1, the present invention has a central processing unit (hereinafter simply abbreviated as CPU) 2, a power supply device 1, and an automatic power supply control device 4, to which a remote terminal device 6 is connected via a line. The information processing system is provided with a line procedure control means 7 and a line switching means 8, and transmits a power-on signal and a disconnection signal of the automatic power control word W4 to the line switching means 8 together with the power supply 1, thereby switching the remote terminal line. The connection is switched to the CPUZ side when the power is on, and to the line procedure control means 7 side when the power is off.

Therefore, even if the power is cut off and the CPU 2 is stopped, the remote terminal line remains in a communicable state.

Therefore, by outputting the status check result of the power supply device 1 by the line procedure control means 7 to the remote terminal line and displaying it on the remote terminal device 6, it is possible to check whether or not the power supply device 1 has definitely stopped. It can be confirmed on the remote terminal 6.

Also, when the power is turned on, the automatic power supply control device is activated via the line procedure control means 7 via the remote terminal line (2), and the power supply value fil is activated.

[For production]

The line switching means is reversed using the power-on signal and disconnection signal to the power supply device, and the remote terminal line is switched to the power-on state.
By connecting to the CPU when the power is N and to the line procedure control means when the power is OFF, it is possible to check the power status and issue commands to turn on the power on the remote terminal even when the power is OFF.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

First, the remote terminal 6 that can control the center is defined as a special terminal for center operation. This remote terminal 6 is connected to the CPU 2 installed at the center via a line. Note that 3 is a CCP (communication control processing unit) and 9 is a modem.

The above CPU2. Various devices installed at the center, such as the CCP 3, receive power from the power supply value W1 and are automatically turned on and off in response to power on and off signals from the automatic power supply control device 4.

1- In addition to the power distribution device 1, it is also possible to configure, for example, the air conditioner 5 of the center to automatically turn on and off the power under the control of the automatic power control device 4.

In this embodiment, the line procedure control means 7 is installed at such a center.
and line switching means 8. Line switching means 8
switches the connection of the line to the remote terminal 6 in response to the power-on and power-off signals sent from the automatic power control device 4. That is, the line switching means 8 is switched to the CP IJ Z side (upper side in the figure) by the power-on signal, and to the line procedure control means side (lower side in the figure) by the disconnection signal.

Therefore, the remote terminal line is CI while the power is on)
U2 is connected to the line procedure control means while the power is off.

- The line procedure control means 7 includes a line procedure support section;
The apparatus includes a power state recognition section, a message exchange section that sends a message corresponding to the recognized result, and a power-on signal control section.

In addition to its normal functions, the automatic power control device 4 has the additional function of receiving a power-on instruction from the line procedure control means 7 and outputting a power-on signal.

In addition, the automatic power supply control device 41 line procedure control means 72 in the same figure
Line switching means8. The power supply for the modem 9 on the center side is separated from the power supply 1 described in 2 above and kept on at all times.

Next, the operation of this embodiment will be explained.

To turn off the power to the center by remote control, a power cut command is sent from the remote terminal 6.

This command is sent to the CPU 2 via the line, and then transmitted to the automatic power supply control device 4. The automatic power supply control device 4 sends a power cutoff signal to the power supply device 1 and the air conditioner 5 based on the above command.
At the same time, it is sent to the line switching means 8.

When the power supply device 1 and the air conditioning bag N5 receive this disconnection signal, they turn off the power. The power status is sent to the line procedure control means 7, and the power status recognition unit turns off the power.
It is recognized whether the

The message exchange unit sends a message corresponding to this recognition result. The line switching means 8 is inverted by the aforementioned power cutoff signal, and the line procedure control means 7 side is previously connected to the remote terminal line. Therefore, the message is sent to the remote terminal 6. Remote terminal tJ!
16 displays the sent message as described above on the display device.

In this way, a message corresponding to the power status is displayed, so it is possible to check on the remote terminal 6 side whether or not the center power supply unit t and air conditioning bag W5 have been reliably disconnected. . Therefore, when the power is turned off, there is no need for the operator or security guard at the center to check the power supply as in the conventional case.

In addition, when turning on the power, a power-on time is set in the calendar timer, etc. of the automatic power control device 4, and a power-on signal is automatically output at this time, and the power value W1 and the power of the air conditioner 5 are automatically turned on. However, if it was necessary to turn on the power earlier than the above time, conventionally the operator had to turn on the power manually.

In this embodiment, even in such a case, the power can be turned on at any time by sending a power-on command from the remote terminal 6.

Since the line switching means 8 has been switched to the lower side of the figure, the distribution power supply turn-on command is input to the line procedure control means 7. When the line procedure control means 7 receives this command, it outputs a power-on instruction to the automatic power supply control device 4. The automatic power control device 4 sends out a power-on signal based on this instruction.

The power bag w1 and the air conditioner 5 are activated by the power-on signal, power is supplied to the CP 02, etc., the line switching means 8 is switched to the In side in the figure, and the remote terminal line is connected to the CP tJ 2. The Rukoto.

In this embodiment, even when the power is turned on at a time other than the set time, there is no need for human intervention, and the operation can be performed from the remote terminal 6.

〔Effect of the invention〕

As explained above, according to the present invention, after turning off the power to the center by operation from a remote terminal located at a remote location, the status of the power supply and air conditioning of the center can be checked;
It is also possible to instruct the center to turn on power and air conditioning at any time.

Therefore, when a center user wants to use the center after the center's work is finished, there is no need to leave the center staff behind.
