Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply control system, and more particularly to a 1# power supply control system suitable for improving the operability of powering on/off a computer system having a work station.

　　　　.

PRIOR TECHNOLOGY The general power control methods for computer systems that have been used in the past include α) A method in which each device is powered on and turned off by Yta; 2)
A method of turning on/off the power of the entire central system unit at once O) A method of turning on/off the power at a specified time (There is a method of turning on/off the power according to commands from 4 host/combiners, etc.) However, they do not control the power of work stations installed at data generation sites that are far away from the central system unit. If this were done, the work station, which may or may not be used, would have to be powered on, which would pose a serious problem in terms of safety and labor savings.

However, it is now generally accepted that work stations are more efficient than conventional batch-based processing, making it possible to use work-stages early in the morning, for legal subversion, etc. This is desirable. The problem here is how to control the power on/off of the central system equipment when the person in charge of the central system equipment is absent, such as early in the morning or late at night. . It is an economical problem to have an operator on standby at the central system equipment in response to usage requests from the work station side. Powering on/disconnecting tubes also wastes a lot of time. Moreover, work station users are inexperienced in handling central system equipment, and consideration must be given to this.

OBJECT OF THE INVENTION The present invention has been made in view of the above circumstances, and its purpose is to eliminate the above-mentioned gap II in the conventional power supply control system, and to enable the user to use a work station from there. 〈 (Usually, several Ion ~ 1.5
The purpose of the present invention is to provide a power supply control method that enables control of the power supply sound of a central system device located at a distance of about Km). In a system consisting of a work station installed at a location remote from the apparatus, and a work and station control device connected to the central processing unit and controlling the work station, there is a system failure in the work station control device. A polling control section operated by an auxiliary power supply that operates even during operation is provided, and a convention corresponding to the state of the work station is set between the polling control section and the leak stay 912, and the polling is performed based on the # convention. The power source control system is characterized in that the central processing unit and the work station control unit are turned on/off in accordance with the state of the work station under the control of the control unit. Ru.

Embodiments of the Invention and Effects Thereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a four-dimensional diagram showing an overview of a work stage system according to an embodiment of the present invention. This system includes a central processing unit (hereinafter referred to as "oPU"), input/output devices (not shown) such as disk devices and line printers, and offices, factories, warehouses, etc. where data is generated. Section F'5 A large number of workpieces with 22 crotches.
Station (hereinafter referred to as jW8J) 6□, 6. ,
...6m and a work station control device (hereinafter referred to as WsOJ) 2 that controls these.

W2O3 is connected to ws6 m6 m . . . 6m by a coaxial knurple δ, *6@* .

1m W2O3 is the Mitaro Pursessa (PROO) 8. which controls the entire W802. A storage device (Ms) Q for storing an area and a mital processor 8 necessary for the operation of the mital processor 8.

It consists of a channel adapter (OA) 7 that connects wsa2 and 0Ptrl with Yt, and a polling adapter (hereinafter referred to as "HTJ") 10 that controls the transfer of information to ws and monitors the barks of each ws. ing. (lPt71 and) ILAlO removed (180
2 (i.e. channel adapter 7, mital processor 8 and memory! # information 9) are respectively connected to power supply 1.
131,3. The tau receives power necessary for its operation from the power supply device (main power supply device) 3. The command to turn on/off the power to the diagnostic power source 1tW3 is performed by the power control s17 from the operation panel (not shown) or the power control 1116 from the RLAIQ, and the command is also sent via the power control line 18t. Controls powering on/off of other central systems. Also, HIIAIO in wso2
receives power necessary for operation from the HLA auxiliary power source (for example, a battery, etc.) 4 through power supply #4.1.

The operation of this embodiment configured as described above will be explained below.

α) When the system is not in operation In this case, only the HLAIQ auxiliary power supply 4 is powered on, and only %at*1o is operating. The power supply device 5 is turned off, and the HL of 0PU1*vso2
The parts other than the system 10 and the input/output devices connected to the system have stopped operating.

■If there is an operator on the central system unit side when starting system operation, the operator operates the power-on switch on the operation panel, and a power-on command is transmitted to the power supply unit w3 through the power control #IT'. be done. As a result, the power supply device 3
At the same time as starting the supply of power to the UI and wsa2, it returns the power control $18 and issues a power-on command to other central system devices such as the file system. In response to this command, the central system unit is powered on and the system is ready for use.

In this case, it goes without saying that all of the input/output devices making up the central system **Tt may be powered on, or only the necessary input/output devices may be powered on.

6) During system operation, when the 1802 receives a command from the CIPUl via the channel adapter 7, the microprocessor 8 executes the command for the specified WS according to the microprogram stored in the storage device 9. It issues commands such as read/write via HLA 1.0 and controls the transfer of information. In addition, if the idle state tP is also set, HLAIO
indicates the status of each VS (in use/not in use, online/
offline, gt power on/off, service suspension, etc.).

(4) When the system operation is finished, the operator on the central system side operates the power-off switch on the operation panel to issue a power-off command to the power source 1111111111 line 17'? Then, the signal is transmitted to the power supply section f13, and then it ends. As a result, the power supply device 5 pieces 0P171. At the same time as the power supply to W2O3 is stopped, a power cut command is sent to the aforementioned central system unit through the power control line 18. This command turns off the power to the entire central system unit and stops using the system. However, even at this point, the %HIIm 10 receives power from the auxiliary power source 4 and monitors the status of each W8 in the same way as in the idle mode.

Hereinafter, the monitoring operation by the U7 module 10 described above will be explained in detail using FIGS. 2 to 6.

FIG. 6 shows each state of the WS (in this case, in use/not in use/power off) and responses returned accordingly.

Next, the power-on control and power-off 19i control of the central system device from the WS side will be explained.

α) While the power-on control system is stopped, as described above, only the auxiliary 111 [4] is powered on, and only the IIIAIO is operating. HLAIO sequentially polls each WS as described above and determines the status of each w8. This determination is made based on the criteria shown in Figures 4 and 5 above. In other words, are all W8s powered off? No response in Mongolia (Response 3)
In this case, the above polling is repeated, but even one device is V
When the power of the S is turned on and response 2 is returned, the sequencer 14 defoods and detects this (determines that the power of the WS has been turned on), and - instructs the power control unit 15 to turn on the system power. issue. □Power control unit 15 is power control unit 1
6, a power-on instruction is issued to the If device 3. As described above, the power supply device 13 starts supplying power to 0PUI and Wso2, and at the same time issues a power-on instruction to other central system devices. As a result, the central system device starts operating, and the system can be used from the WS.

[F] When the power cut-off control system is in use, the power supply device 3. W802 and the central system unit in the middle are also powered on and are 1u:t, AIO.
The auxiliary power source 4 is also powered on.

WS is currently running various jobs, and 1 (LAlo
Open information transmission with WS without L-ring each W8,
The status is being monitored. When the job in each w8 is completed and all wBs are powered off/off, the HLAIO detects response 3 (no response) from all WSs due to the above-mentioned giring. As a result, the first shift of the sequencer can handle all WSs.
It is determined that the power is turned off, and an instruction is issued to the power control unit 16 to turn off the power. A power cut command is transmitted to the power supply device i3 through the power control signal 16. As a result, the h1 power supply device F3 stops supplying power to 0PUI and wso2, and at the same time, the power supply device F3 stops supplying power to the power supply unit I! The above-mentioned through 181ft

However, even at this point, HLAlo is receiving power from the HLA auxiliary lightning source power supply and continues polling to the WS in order to monitor power-on in the fall.

In the above embodiment, the response of each WS to polling from )ILAIO is identified by 7 lags 1, but the invention is not limited to this. For example, the patent identification may be included in the response message It goes without saying that it is okay to include information in any way you like.
