Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an automatic power-on control device Kl for an information processing system.
I do it.

Conventionally, when turning on the power to an information processing system, the system operator would turn on the information after the power was turned on to the ancillary equipment necessary for operating the information processing system (air conditioner 1 distribution board, etc.). It was necessary to turn on the power to the sensitive layer system. Therefore, when the information processing system starts operating, the system operator must always turn on the power to the information processing system and its auxiliary equipment. In addition, it is possible to turn on the terminal device by simply detecting a change in the signal line of a part of the modem in the terminal device, but in this case, the power is turned on automatically due to noise and Additionally, there was a safety problem in that 14 unauthorized persons could freely turn on the power.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic power-on control device which eliminates the above-mentioned drawbacks.

In order to achieve the above-mentioned objectives, an automatic power-on control device according to the present invention includes a modem signal control means for receiving a power-on request signal whose state changes a predetermined number of times sent from a modem device, and a state control device for receiving a power-on request signal that changes state a predetermined number of times from a modem signal control means. a time creation means that is activated by a change signal and creates a predetermined time; and a measurement means that counts the number of state changes and outputs a signal indicating the number of times when a predetermined number of times has been counted. , logic means for outputting a signal permitting power-on when receiving the output of the measuring means within the predetermined time;
power-on control means that is connected to an information processing system component and ancillary equipment of the component and outputs a power-on signal under certain conditions on the information processing device side when receiving a signal permitting automatic power-on; The system is configured to include notification means for notifying the remote terminal of the success or failure of turning on the 1llc power, and is configured to automatically turn on the power of each device connected to the information processing system via the 1 communication line from the end of the remote terminal. .

According to the above configuration, safe unmanned operation and labor-saving automatic operation of the information processing system are possible, and the object of the present invention can be completely achieved.

Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like. FIG. 1 is a system block diagram mainly showing the power control portion of an information processing system incorporating an automatic power-on control device according to the present invention to automate power-on of each device and its ancillary equipment. When a calling signal requesting power-on is sent from a remote terminal (not shown) via a public communication line, the modem A power-on request is notified through a call break signal C (hereinafter abbreviated as CI signal) line, which is one of the signal lines 51. Power sequencer 4. The electric light 5 and the air conditioner 6 are configured to be powered on by the power-on signal signal of the automatic power-on control value [13] output based on the OI flaw signal. The success or failure of power-on is notified from the automatic power-on control device 3 via N0U1 to a remote terminal (not shown) that requested power-on.

FIG. 2 is a block diagram showing an embodiment of an automatic power-on control device according to the present invention.

When the above-mentioned CI signal is input to the modem control unit 7 which is the modem signal control means, the modem control unit 7 transmits the signal to the modem signal line 5.
When the data terminal ready signal line, which is one of the data terminal ready signal lines, is turned on, the KOI signal is simultaneously sent to the counter 8, which is a measuring means, through the signal line 52 and to the AND circuit 15 through the signal line 54, respectively. The counter 8 counts +l based on the above signal. On the other hand, since the signal indicating 0 (initial value) before counting is also input to the AND circuit 15 via the signal line 53, the AND circuit 15 uses this signal and the CI ON signal of the signal line 54 to The timer 9, which is the creation means, is activated. In this state, the CI flaw signal from the remote terminal is sequentially counted by the counter 8. The counter 8 has a predetermined value indicating a power-on request set as an overflow value, and outputs the signal to the signal line 55 when the CI flaw signal overflows.

If the OI fault signal sent from the modulator/demodulator is accepted and the power-on request is from the 9th terminal, the overflow output of the counter 8 will be output to the signal line 55 within the time predetermined by the timer 9. Become. To be sure, the output signal line 71 of the tie 19 is still "0" and the signal line 56 passing through the inverter becomes 111, so the output signal line 57KId of the AND circuit 14, which is the logic means, is allowed to be powered on. signal,
That is, a "1" signal is output. On the other hand, if the request is not from an authorized terminal, tie! Since the overflow value is not counted and becomes 1 within the predetermined time set by 9, the AND circuit 14 has up to 1 of 1.0#.

When the predetermined time has elapsed, the timer circuit outputs a timeout signal to the signal line 71 and resets the counter 8 via the OR circuit 16. The light timer 9 is also reset by a signal that allows the AND circuit 14 to be powered on, and the counter 8 is also reset through the same route as above.

The power-on control unit 19 is activated by the power-on permission signal, and turns on the power to the air conditioner, electric light, and device 1#, respectively. First, when the power-on permission signal is input, a power-on control signal is sent to the air conditioner via the signal line 58. Next, the power sequencer 4, which sequentially powers on the information processing system components (not shown), is activated, but this is performed according to the following operation. That is, when the power-on control unit 10 is activated, the timer 11 is also activated at the same time, but this is for creating a predetermined time, as in the case of the timer 9. Therefore, before starting the power sequencer, a sensor (not shown) monitors whether the temperature inside the computer room is within a specified value, and within a predetermined time set by the timer 11, the signal line indicates that the temperature inside the computer room is within the specified value. 61 becomes @l'', the power-on control unit lO resets the timer 11 via the signal line 62, and then also starts the power sequencer 4 via the signal line 59.The power sequencer 4 thereby performs each operation in a predetermined order. Turn on the power to the device, and at the same time turn off the power on control unit again.
1l is activated via the signal line 63. At this time, the electric light 54 is turned on via the signal line 74 as required by the system.

Next, the internal pressure ready signal line 6 for a predetermined time of the timer 11
When the power sequencer 4 notifies the completion of successive power-on of the system component devices via the signal line 63, the power-on control section resets the timer 11 via the signal line 63. After this,
The power-on control unit 1O connects the data transmission unit 1 to the data transmission unit 1 via the signal line 6S.
Notify z that power has been turned on. The data transmitting section 12 receives this and activates the NOU control section 13 via the signal line... to signal I! 67 is used to control the dial pulse transmission of the sender registered in advance to NCIUIK. N
When the source is connected via 0Ul, the data transmitter l
z controls the modem controller 7 to transmit a power-on completion message (not shown) to the remote terminal via the signal line 68. The power-on completion message is modem 2. The remote terminal is notified via N0Ul. If the temperature of the computer room is not within the specified value within the predetermined time of the timer 11 after the power supply of the air conditioner 6 is turned on (when the logical value of the signal line 61 is @O''),

If there is no ready signal 64 response from the power sequencer 4 within the time specified by the timer 11 after starting the power sequencer 4, the data transmitter 12 is notified via the signal line 65, and the same method as above is used. The data transmitter 12 notifies the remote terminal that power-on has failed. Power-on control section 1
0 is notified by the timeout signal 70 of timer +11 whether a predetermined time has elapsed. Note that the counter 8 receives the timeout signal 71. of the timer 9. or thai ff1l
When the timeout signal 72 or the logical sum 16 of the signal line 73 having the same polarity as the signal line 65 is established, it is reset (initial value - 0).

In the present invention, the power source of the automatic power-on control device 3 itself is
It is assumed that the automatic power-on control device 3 is always turned on, but when using a public communication line, it is also possible to turn on the power of the automatic power-on control device 3 itself by changing the CI.

As explained in detail above, according to the present invention, when a remote terminal receives a power-on request via a communication line and satisfies predetermined conditions, it is regarded as a power-on request from an authorized terminal. Since the system is configured to turn on the power to each device and auxiliary equipment, the system operator can safely turn on the power from a remote terminal, enabling unmanned and labor-saving automatic operation of the information processing system. It has the effect of becoming.
