Description

[Detailed Description of the Invention] [Summary] The present invention relates to a power control method for a workstation, and also provides a simple operation to release the inoperable state caused by turning off the power when resources are being used in the workstation. When the power switch is turned off and the equipment resources of the workstation are being used by another workstation, the device is switched to power-off mode and set to an inoperable state, and the workstation that is currently in use is disconnected from the power switch. A workstation whose power is to be cut off upon notification of end of use is provided with a release means for detecting the on operation of the power switch, canceling the set power-off mode and setting the workstation to an operable state.

[Industrial application field]

The present invention relates to improvements in power control methods for workstations.

It has equipment resources such as printers and files, and those equipment resources are used by other workstations,
Furthermore, in a system consisting of a WS that also processes data (hereinafter referred to as the server WS) and a WS that uses those device resources through a line (hereinafter referred to as the client WS), when the power switch of the server WS is turned off, , if the client WS is using those equipment resources,
The server WS is configured to be set in an inoperable state (hereinafter referred to as a power-off mode) without turning off the power, and to turn off the power after waiting for a notice of end of use from the client WS.

In this power-off mode, conventionally, the operation of the power switch is disabled, and therefore, if the user wanted to use the server WS again, the only option was to wait until the client WS finished using it and the server WS was powered off.

Therefore, there is a need for a power control system for workstations that can release the power-off mode with a simple operation.

[Problem to be solved by the invention]

As explained above, turning off the power switch means that the operator wanted to turn off the power, but after that, when the operator wants to use the server WS again, in the conventional technology, the server WS is turned off by terminating the client WS. I had no choice but to wait for the WS to turn off automatically and then turn it on again.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a power control method for a workstation that allows a workstation to be released from a power-off mode and returned to a usable state with a simple operation.

[Means to solve the problem]

In order to achieve the above object, the power supply control system for the workstation of the present invention, as shown in the principle diagram of the present invention, uses the equipment resources 31 provided in the workstation when the power switch 32 is turned off. If the station is in use, it is switched to a power-off mode and set to an inoperable state, and the workstation is turned off in response to a notification of end of use from the workstation in use, detecting an on operation of the power switch 32; A canceling means 33 is provided for canceling the set power-off mode and setting the device to an operable state.

[For production]

The release means 33 detects the ON operation of the power switch 32,
If it is in power-off mode, cancel the power-off mode and set the work stage engine to a usable state.

As a result, the power-off mode can be canceled simply by turning on the power switch 32, and the workstation can be used without waiting for other workstations to finish their use.

■If you turn on the power switch 32 while in the power-off mode, the guidance disappears by the release means 33.
Server WS30 becomes available for use as usual.

■When guidance is displayed on server WS30,
Turn off the power switch 34 of the client WS20.

As a result, the client WS20 notifies the server WS30 of the end of use and turns off the power.

- The server WS30 that receives the end-of-use notification automatically powers off.

Figures 3 and 4 show the functions shown in Figure 1.
The processing flow of the power control processing section 9 on the client WS side and the processing flow of the power control processing section 2 on the server WS side are shown, respectively.

(Processing on the Client WS Side) Refer to FIG. 3 When the power is turned on, the client WS20 issues a use start notification to the server WS30 via the line control unit 11 in an initialization process.

When the predetermined data processing is completed and the power switch off is notified from the SW press notification unit 8, the power processing unit 9
A usage termination notice is issued in S30.

Upon receiving the response from the server WS30, the power-off processing unit 12 is called.

As a result, the power-off processing unit 12
Turn off the power.

(Processing on the server WS side) See Fig. 4 When the usage start notification is received from the line control unit 4, the state is set to "Client WS in use", and upon the usage end notification, the state is changed to "Client WS not in use". Set.

When there is a switch press notification (on/off is not distinguished below), if the client WS is in use, it will be set to power off mode and guidance will be displayed, and if the client WS is not in use, it will be turned off. The disconnection processing unit 7 is called.

When the use end notification is received, if the power-off mode is present, the power-off processing unit 12 is called.

The above is the same as conventional power supply control.

If the switch press notification is received and the server is in the power-off mode, this notification indicates that the power is on, so after erasing the guidance display, the power-off mode is canceled and the server WS30 is returned to a usable state. (This part corresponds to the release means 33) [Description of other embodiments] (1) The above has been explained in terms of the relationship between the single client WS20 and the server W330, but the relationship between multiple clients WS20 and the server WS30 The functions in are also similar. In this case, at least one client WS2
When 0 is in use, the server WS is turned off by the power switch 32.
30 cannot be powered off, guidance is displayed, and when the end of use of all clients WS20 is notified, the server WS30 is automatically powered off. When the power switch 32 is turned off again before all the clients WS20 are powered off, the guidance disappears and the server WS30 becomes usable again.

In order to realize this function, as shown in FIG. 5, a counter control process is added that indicates the number of client WSs in use, and is incremented by 1 at the start of use notification and -1 at the end of use notification. When the usage end notification is -1, the counter becomes O, and
If the guidance is displayed, start the power-off processing section 7,
Perform power-off processing. When the power switch 32 is pressed again before the counter reaches 0, the power-off mode is canceled, the guidance disappears, and the WS function of the server WS30 can be used as before the guidance was displayed.

(2) In addition to the counter control described above, there is also a table control method. This means that the client W
The number of S20 is stored in the table, and the corresponding number is deleted with the end-of-use notification. Then, by referring to the contents of this table, it is determined whether to execute power-off.

(3) When in the power-off mode, when returning to the normal mode, control may be performed by pressing a specific key on the keyboard instead of the power switch 32.

〔Effect of the invention〕

1. Even when the server is in power-off mode, the WS function of the server WS can be used by simply pressing the power switch again.

2. Regardless of whether you want to turn off the power or use the WS again in power-off mode, all power-related operations can be performed by pressing the power switch.
Operations are not complicated.
