Abstract

PURPOSE:To prevent the job of an information processing unit from being interrupted because of the unconditional disconnection of power supply by providing a switch to be switched to either the turning on/off of power supply at set time or the turning off of the power supply by making a power supply disconnection signal outputted from the information processing unit a trigger. CONSTITUTION:If the switch 14 is switched previously to a side (a dot line side) to turn on/off the power supply at the time set from a panel 16, since the power supply disconnection signal (d) outputted from a timer 13 is sent to a power supply turning on/off device 15, when it becomes the time set beforehand, the power supply having been supplied to the information processing unit through an output side power receptacle 18 is turned off by the power supply turning on/off device 15. Besides, if the switch 14 is switched previously to the side (a full line side) to turn off the power supply by making the power supply disconnection signal (a) from the information processing unit the trigger, the power supply disconnection signal (c) is sent to the power supply turning on/off device 15 in accordance with the power supply disconnection signal (a) from the information processing unit. Trouble that the power supply is turned off unconditionally and the job of the information processing unit is interrupted is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic power on/off device that is connected to an information processing device including a computer and peripheral devices, and that automatically turns on and off the power of the information processing device. This invention relates to an automatic power on/off device.

[Conventional technology]

Conventionally, this type of automatic power-on/off device sets the power-on time and power-off time on the device panel, and either turns the power on and off at the set times, or when there is no key input for a certain period of time. , and when there is no job being executed in the information processing device, the power is cut off using a power cutoff signal from the information processing device as a trigger.

[Problem to be solved by the invention]

The above-mentioned conventional automatic power on/off device sets the power on time and power off time on the panel of the device and turns on and off the power at the set times, or turns off the power from the information processing device. The power is turned off using a signal as a trigger, but in the former case, the power remains on even when the information processing device is not in use, which is reasonable in terms of power consumption and hardware lifespan. On the other hand, when the power is cut off, even if there is a job being executed in the information processing device, the power is cut off, resulting in the job being interrupted.

Furthermore, in the latter case, there is a problem in that when a power cutoff signal is sent from the information processing device, the power is cut off each time the information processing device is normally used.

An object of the present invention is to turn off the power to an information processing device when it is not in use, thereby saving power consumption and prolonging the life of the hardware. Jobs on the information processing equipment will not be interrupted due to a power cut, and the power will not be cut off even during the time when the information processing equipment is often used. An object of the present invention is to provide an automatic power on/off device.

[Means to solve the problem]

The automatic power on/off device of the present invention is an automatic power on/off device that is connected to an information processing device and includes a power on/off means for controlling supply power on and off to the information processing device. ) an input means for setting the time and conditions for controlling the power on/off of the power supply; (B) an input means for setting the time and conditions for controlling the power supply on and off; (C) a first switch that is turned off within a power-on securing time period set as a time period for which the power supply is turned on; a timer that outputs a signal and a power cutoff signal, and outputs a time signal indicating the energization secured time period when the time of the energization secured time period arrives; (D) controls the disconnection of the power supply from the input means; When a control signal that sets a condition is received and the circuit is switched to turn on and off the power at the set time, the power on signal and the power off signal output from the timer are used to turn on and off the power. when the circuit is switched to cut off the power supply using the power cutoff signal outputted from the information processing device as a trigger;

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The automatic power on/off device shown in FIG. 1 includes an input side power outlet 17 that receives power supply from the outside, an output side power outlet 18 that supplies power to the information processing device, a decoder 11 that receives and decodes a power cutoff signal, In order to continue supplying power to the information processing device even when the information processing device is not in use, a switch (the first switch ) 12. When the time to control the supply power on and off set by the display operation unit 16 is reached, a power on signal and a power off signal are output respectively, and when the time of the energization ensuring time period comes, energization is ensured. A circuit that receives a timer 13 that outputs a time signal indicating the time zone, and a control signal that sets conditions for controlling the disconnection of the power supply from the display operation unit 16, and turns on and off the power at the set time. (dotted line side) or switch the circuit (solid line side) to turn off the power using the power cutoff signal a output from the information processing device as a trigger.

(input means) 16.

Next, the operation will be explained.

First, the operation on the information processing device side will be explained.

FIG. 3 is a flowchart showing the operation of the information processing device.

As shown in FIG. 3, on the information processing device side, a timer for monitoring key human power is set (step 3A), and while the job is being executed (step 3B), key human power is monitored (step 3C) for a certain period of time. If there is no job and a timeout occurs (step 3E), it is further confirmed that there is no job being executed (step 3F), and a power-off signal a shown in FIG. 1 is transmitted (step 3G). If the power is not turned off even after transmitting the power cutoff signal a, the process returns to step 3A and the same process is performed.

Next, the operation of the automatic power on/off device will be explained.

FIG. 2 is a flowchart showing the operation of the automatic power on/off device shown in FIG.

As shown in FIG. 2, the decoder 11 receives the power-off signal a transmitted from the information processing device (step 2A),
When the received power cutoff signal a is decoded (step 2B) and determined to be a power cutoff signal (step 2C), the power cutoff signal a is sent to the switch 12 as a power cutoff signal.

Since the switch 12 is turned off during the preset energization time period during which the power supply cannot be cut off by the power cutoff signal from the information processing device,
If it is outside the set time period (step 2D), the power cutoff signal passed through the switch 12 is sent to the switch 14 as a power cutoff signal C. Furthermore, if the switch 14 is switched to the side (solid line side) that turns off the power using the power cutoff signal a from the information processing device as a trigger, the power cutoff signal C is sent to the power on/off device 15. It will be done.

Then, the power input from the input side power outlet 17 and supplied to the information processing device via the output side power outlet 18 is cut off by the power on/off device 15 (
Step 2E).

Since the switch 12 is in the OFF state during the set power-on securing time period, the information processing device does not send the power-off signal a.
Even if received, it does not reach the power on/off device 15, so the power is not turned off.

In addition, if the switch 14 is switched to the side (dotted line side) that turns on and off the power at the time set on the panel, the power off signal d output from the timer 13
is sent to the power on/off device 15, so when the preset power off time comes, the power supplied to the information processing device via the output side power outlet 18 is cut off by the power on/off device 15. Further, the power is turned on by sending a power-on signal from the timer 13 to the power-on/disconnect device 15 at a set time.

Since the switch 14 is switched to the side that cuts off the power by using the power cut signal from the information processing device as a trigger, the power is cut off unconditionally and the job of the information processing device is interrupted. There is no need to put it away.

Note that the switching state of the switch 12 described above is determined by the display operation section 1.
The timer 13 is controlled by the timer 13, which is set with the energization securing time from 6.

Furthermore, the switching state of the switch 14 described above is determined by the display operation section 1
It is controlled and set from 6.

〔Effect of the invention〕

As explained above, the present invention enables rational operation in terms of power consumption and hardware life by cutting off the power when the information processing device is not in use, and the power is cut off unconditionally. This has the effect of preventing the job of the information processing device from being interrupted due to the interruption of the job of the information processing device, and also of preventing the power from being cut off during the time period when the information processing device is normally used.
