Description

DETAILED DESCRIPTION [Overview] In a system that controls a power supply device of an information processing device by a command from the information processing device, the power supply device supplies power when a command instructing power off is issued. The information processing device is stopped because it is disconnected. Therefore, if a command is issued to confirm the function of a command to turn off the power in a test program configured to execute several test modules one after another, the test is interrupted at that point. However, there was a problem that the work was inefficient because the intervention of acquisition was required to restart. In order to solve such a problem, the present invention sets the control state of the power supply control device to a special control for diagnosis, and when a power-off command is received, the power-supply control device does not actually turn off the command and It discloses the configuration of a power supply control device having a function of confirming the operation by reporting to the information processing device that the information has been normally received, and also capable of continuing the test thereafter.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that controls a power supply device that supplies power to an information processing device, and particularly to control when a command to cut off power is received from the information processing device. Pertain to.

[Prior Art] FIG. 2 is a diagram showing a configuration of a power supply system of an information processing apparatus, where 1 is an information processing apparatus, 2 is a power supply apparatus, 3 is a power supply control apparatus, 4 is a power supply section of the power supply control apparatus, Reference numeral 5 represents an operation panel.

In FIG. 2, the power supply device 2 creates a stabilized DC power supply based on a commercial AC power supply (AC100V or AC200V) and supplies it to the information processing device 1. The power supply device 2 is controlled by the power supply control device 3.

That is, the start / end of the operation of the power supply device 2 (opening / closing of the power supply to the information processing device 1) is performed by the power supply control device 3 which receives this signal when the switch provided on the operation panel 5 is operated. This is performed by controlling the power supply device 2 with the power supply control signal. Normally, there are a plurality of types of DC power supplies supplied to the information processing device 1, and the power supply control device controls so that the order of turning them on or off does not adversely affect the circuit elements of the hardware of the information processing device. ing. Then, the power supply control device 3 can control the operation of the power supply device 2 by decoding the command received from the information processing device 1 in addition to the control by the switch on the operation panel 5.

[Problems to be Solved by the Invention] In an information processing system, maintenance and inspection are usually performed in order to ensure system reliability.
In addition to maintenance of input / output devices having mechanically movable parts, these tests test whether or not instructions are correctly executed by the information processing device. Is run on the information processing device.

That is, the test program executes various instructions, determines whether or not they are normally performed, and outputs the result.

In the operation of the information processing system, the above-mentioned test program is usually run at the time of system startup or at the end of work to detect the abnormal state before the system reliability is ensured. Often endeavoring to

In such a test, when a command is issued in the test program to instruct the information processing device to be powered off, the power is cut off and the information processing device is stopped. It stops and it becomes impossible to continue the test.

Therefore, there is a problem that the test for the command for turning off the power supply of the information processing device cannot be performed in the test program.

The present invention has been made in view of such conventional problems, and an object thereof is to provide means for performing a test of the function of a power-off command of an information processing apparatus in a test program.

[Means for Solving Problems] According to the present invention, as described in the claims, the above object controls the operation of a power supply device that supplies power to the information processing device according to an instruction from the information processing device. Is a device capable of switching between normal control and control during diagnosis, and the power supply is turned off when a command for turning off the power is received from the information processing device during control during diagnosis. The present invention is achieved by a power supply control device characterized by including means for making a response to the information processing device that a command for turning off the power supply has been normally received without giving an instruction for starting the operation.

[Embodiment] FIG. 1 is a block diagram showing a configuration of a power supply control device according to an embodiment of the present invention. 6 is a CPU interface, 7 is a panel interface, 8 is a power supply interface, 9 is a time table, and 10 is a time table. Is a calendar clock, 11 is a control unit, 12 is a diagnostic control unit, and 13 is a power supply unit.

In FIG. 1, the panel interface 7 sends a signal to the control unit 11 when a switch or the like on the operation panel is operated.
Tell. Items that can be instructed on the operation panel include turning on / off the power of the information processing device and switching between normal control and diagnostic control.

When the control unit 11 receives a power-on or power-off signal from the panel interface 7, it sends a control signal to the power supply device via the power supply interface 8 to control the power supply device.

When a signal instructing to switch the control to the diagnostic control (hereinafter, also referred to as a diagnostic mode) is received, a part of the control (control at the time of receiving a command described later) is performed by the diagnostic control unit 12. Set to.

The power of the information processing device and the switching to the control diagnostic mode can be performed by a command from the information processing device. That is, when these commands are sent to the control unit 11 via the CPU interface 6, the control unit 11 analyzes the commands and performs the instructed operation.

Regarding turning on / off of the power, the time to turn on / off the power is set in advance in the time table 9, and when the time is reached, the control unit 11 issues a control signal corresponding to the power supply unit. It also has a timer function.

When the control is switched to the diagnostic mode, the diagnostic control unit 12 receives the command (including the disconnection to specify the time) from the information processing device to shut off the power to the power supply device. A response indicating that the command is normally received is sent to the information processing apparatus without issuing an information signal.

Therefore, if the information processing device sets the power supply control device in the diagnostic mode in advance in the test program, it can be confirmed that the command for instructing the power supply to be cut off is normally received by the power supply control device, and the test can be continued thereafter.

[Effect of the Invention] As described above, according to the power supply control device of the present invention, in the diagnostic mode, even if the power-off command is received,
As a result, only the reception status of the command is reported to the information processing device without sending a control signal for instructing the power supply device to turn off the power, so that the information processing device does not stop, so acquisition intervention is not required. It is possible to continuously perform a series of tests including a test of a power off command.

Therefore, there is an effect that a system start-up and a regular test at the end of work can be efficiently and promptly performed.
