Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic power-off method for an information processing device, and more specifically, to information that allows the power to be cut off in response to a power-off signal incorporated in a program. The present invention relates to an automatic power-off method in a processing device.

[Conventional technology]

Conventionally, in online information processing equipment using computers, when the system power of the terminal controller that processes information at each terminal is turned off, the execution of the basic program that executes the main business of this information processing equipment is first terminated. , an automatic power-off method using a so-called timer function has been adopted in which the system power is turned off after a certain delay time has elapsed.

[Problem that the invention seeks to solve]

However, this type of power-off method using a timer function is configured to unconditionally turn off the power to the information processing device after a predetermined period of time has elapsed.
There are cases where it is not possible to reliably complete the execution of an unspecified user program uniquely assigned to each terminal controller. Therefore, it is practically impossible to set a user program that needs to be completely executed to be executed when the timer function is activated.

On the other hand, if the time constant of the timer function described above is set to a large value so that all user programs always complete execution, the terminal controller must continue to operate for an extra period of time, and the power can be quickly turned off and the information processing device There was a problem that the efficient use of the materials was hindered.

[Means for solving problems]

The automatic power-off method according to the present invention has been developed in view of the above-mentioned problems, and includes executing an application program after the execution of the basic program is completed, and detecting the establishment of a condition for power-off during the execution period. The information processing apparatus is characterized in that the information processing apparatus is powered off in response to the detection.

That is, the feature is that after the execution of the basic program is finished, the device is powered off based on a determination function built into the application program rather than a timer function.

〔Example〕 Hereinafter, the present invention will be explained in detail based on examples.

FIG. 1 shows the hardware configuration of a terminal controller 1, which is an information processing device suitable for implementing the present invention.

In the figure, a central processing unit 2 connected to an external host computer (not shown) via an online network includes a program memory 3 in a terminal controller 1 and an auxiliary writing device 4 comprising a magnetic disk system, etc.
, and a PLLJ memory 5 in which product price data is stored. Power inside the terminal controller 1 is supplied from an automatic power supply controller 6, and its connection and disconnection are controlled by control commands from the central processing unit 2. The program memory 3 stores a basic program R3-1 that handles main tasks such as calculation processing, and an application program section 3-2 that handles auxiliary tasks such as modifying product mask files and checking PLLI memory. ing.

The central processing unit 2 communicates with the host computer according to the contents of the basic program section 3-1, processes daily online operations, and then performs auxiliary operations according to the contents of the application program section 3-2. and finally issues a power cut signal to the automatic power controller 6. The automatic power supply controller 6 that receives the power cutoff signal cuts off the power and completely ends the day's work.

FIG. 2 is a diagram showing a power-off processing flow according to the present invention.

That is, when the terminal controller 1 finishes its work for the day, the power off check process (step ■) determines that (1) it is within the time set by the terminal controller 1 (the period can be changed); ) Each execution program has finished its operation, (3) System termination processing of terminal controller 1 (basic program section 3)
-1 included. ) has been completed, and (4) that no online installation request has been made. If all conditions are satisfied, proceed to the next step; if not, return to the previous step.

Next, after waiting for a predetermined time (step ■), step again
If the conditions are unsatisfactory, the process returns to the beginning, and if the conditions are satisfied, the final price data is stored in the PLU memory (step ■). Next, it is determined based on predetermined data whether or not that day is the beginning of the month, and if it is the beginning of the month, the files that have been updated every day until then are re-created, and if not, it is bypassed (step ■
).

Next, the same check as step (2) above is performed again (step (2)), and if the conditions are unsatisfactory, the process returns to the beginning, and if the conditions are satisfied, a power cut signal is sent to the automatic power controller 6 and the power is cut off ( Step ■).

Of the check conditions in steps ■, ■, and ■ above, if there is an online installation request (condition (4)
), it is necessary to wait for the installation process or post-reception process to be completed and then turn off the power to the terminal controller 1.

The flow of such application processing is shown in FIG.

After starting the process (step ■), the terminal controller 1 checks whether or not product mask data or departmental budget data has been received by the host computer at regular intervals in the online installation request file sense process (step ■). Monitor.

At this time, if the product mask data is received, a product mask correction file creation process (step 2) is executed as a post-reception process. Thereafter, PLU memory check processing (step ■) is executed to check the data in the PLU memory, and product mask maintenance processing (step ■) is performed on the product mask file stored in the auxiliary storage device 4.
I do.

If the data received by the terminal controller 1 from the host computer includes departmental budget data, the departmental budget previous year data creation process (step
).

After completing the product mask maintenance process (step ■) or the departmental budget previous year data creation process (step ■) described above, post-embedding processes such as retry (reprocessing) to be performed in case there is an abnormality in the series of processes (step (2) Execute After receiving, the process ends and returns to step (2) and the processing start point (step (2)).

This series of processes is repeated as long as the embedding request remains, and when the embedding request is finally eliminated, the four condition judgments described above are performed in the same way as the power off check process (step ■ in Fig. 2) explained in Fig. 2. Processing is performed (Step ■ in Figure 3). If all conditions are satisfied, PLU memory save processing as system management processing (step 0)
After performing the file recomposition process (step ■), a power cut signal is issued and the automatic power controller 6 turns off the power to the terminal controller 1 (step 0).
.

If it is determined in the power off check process (step ■) that at least one of the four conditions is not satisfied, the process returns to the embedding request file sense process (step ■) and performs a series of steps. Execute application processing repeatedly.

〔Effect of the invention〕

As explained in detail above, in the automatic power-off method according to the present invention, it is possible to determine whether or not to turn off the power to an information processing device such as a terminal controller during the execution of an application program that is subsequently executed after the execution of the basic program is completed. By incorporating and executing such a determination function, it is possible to automatically and efficiently power off the information processing apparatus.
