Abstract

PURPOSE:To put a system in automatic operation at low cost without requiring any special automatic power source controller by dividing the mechanisms and devices of the system into two groups and providing a power supply device for each group. CONSTITUTION:The 1st group of a memory device 9, CPU2, and circuit attachment 10 is connected to a power supply device 11, and a memory device 8 and peripheral device 3 are connected to a power supply device 12. The power supply devices 11 and 12 are connected to a power controller 13 and the CPU2 is connected to the power supply device 12. The power controller 13 turns on the power supply device 12 by a signal from the CPU2. The CPU2, the 1st memory device 9, and circuit attachment 10 are activated all the time to perform power- up operation by receiving a power-on command from a center side.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a data processing system having a central processing unit, a plurality of memory devices, line attachments, and peripheral devices.

(11) Technology background Automated driving by remote control of computer systems is becoming more and more common.
This number is expected to continue to increase in the future. In order to perform automatic operation by remote control, it is necessary to turn off/on the power of the computer system being remotely controlled. This is because when performing automatic operation by remote control, the computer system is operated only for a short period of time, and in consideration of energy saving, hardware lifespan, and safety, the computer system is only used when it is not in use. It is desirable to turn off the power. For example, in chain stores such as supermarkets, each branch has a
A system has been installed and is connected to the center.

Exchange of sales status between the center and each branch system is generally done at night. This is due to the fact that Center R cannot be used during the day due to other errands, and the late-night charges are low.

Mano, is the power supply on the clock where each branch's computer is waiting? on/
There is a way to turn it off, but if there are many branch offices, each computer system will be connected to the center and the data exchange.
I can't predict whether I'll do IR.

It is difficult to actually use it. In such a system, it is very effective to have the ability to turn on and off all the power to the computer systems at each branch office based on commands from the center when necessary.

For this purpose, there are two conventional methods for turning the power on and off by remote control.

1st Fi, public round 411C! In the case of continuous operation, the device receives the CI injury signal (detects the CI injury signal, turns on the power completely, and goes through the first and second steps in 6 steps). and telegram (1
Waiting for a function that can decipher the t+i control information), the communication M'' deciphers the power on/off from the circuit, and turns the power on/off as a control other than partial control. This is a way to turn it off.

(...) Prior Art and Problems Figure 1 shows a conventional embodiment, where 1 is a main unit, 2 is a central processing unit (hereinafter referred to as CPU), and 3 is a human output #eft. , 4 is the power supply device, 5 is 'aim City I

ing. Also, each power supply device has a 10OV commercial power supply. It continues.

Now, among the two methods, the first method is that when the message sent from the center is manually input to N○σ7, it is immediately sent to ○OU5, and No. 615 becomes the supply signal for power supply device rj14, Start up each device f.

In this case, the power supply device t4 is connected to the incoming signal to the NCU'f.
This will be the supply number for the company.

By the way, the first method is relatively low cost and '+l! Although it is an aT function, it is difficult to deal with the case of an erroneous incoming call because the system may be powered on only by the receiving party.

Also, what is the second method? Although there is no need to turn on the power to the system, the functions of controlling procedures and reading messages are all required by CCIJ5, so the CCU3 has memory and control functions. CIVI becomes necessary, making the device large and expensive.Objective of the InventionThe object of the invention is to eliminate the above-mentioned drawbacks and to provide a system that performs automatic operation at a low price and with a small installation area. purpose.

(φ) Structure of the invention In a data processing device having a central processing unit, a plurality of memory devices, a circuit attachment, and a peripheral device, the data processing device comprises a central processing unit, at least one memory device, and a circuit attachment.

In addition, the central processing unit is configured to at least enable the second power supply unit to start supplying power to the second power supply unit. When the supply FTV is not supplying power, it compares the message sent through the upper central processing unit's power supply attachment with the control information stored in the first memo. It is configured to decode and detect that it is a power-on command, and to start supplying power t'' to the second power supply [i.

If it is a startup command, No. 1 is sent from the 0PU2 to the power supply control device 13, and the power is turned on to the second power supply device 12.

Accordingly, the second power supply device 12 supplies power to the second group, the second memory device 8 and the peripheral device #5, thereby starting up the entire system and performing processing operations. . Information transmission with the center is also carried out through this line.

By the way, when the processing operation is completed, a command to stop the 7 stems is issued from the center, which is decoded by the circuit attachment 10, and the system is turned off, leaving only the first group. The first group always exchanges two lines of telegrams with the center, decodes them, and then performs the next processing operation.

As a result, the vP U 2, the first memory device 9, and the same attachment 10 are always alive and the device jiii
