Description

Power control device with automatic power on function in computer system and method thereof

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system, and more particularly, to a power supply control apparatus and a method having an automatic on function in a computer system for controlling on / off of a computer system.

Computers are currently used for various purposes in various technical fields. The amount of data processed by a computer is getting enormous and it is rapidly increasing in terms of processing speed. However, a computer must receive data and instructions to be processed by a user. As one method of overcoming the limitations of the computer, a program that automatically processes a task pre-input by the user at a predetermined time even without a user's command may be considered. Using such a program, the computer will automatically process pre-entered tasks at a given time, whereby the user can also perform tasks for other processing using the computer, thereby enabling multiprocessing.

However, such a program is operated while the computer is already powered on, so the program must not be powered off to run the program. Therefore, if a user does not use the computer for a long time without performing other processing, the power of the computer must be turned on for the program, and thus there is a problem in that power consumption is high.

SUMMARY OF THE INVENTION The present invention provides a power control apparatus having an automatic power-on function in a computer system that checks every hour to automatically turn on / off the computer power, thereby automatically processing a desired task while reducing power consumption. To provide.

Another object of the present invention is to provide a power control method for an automatic power-on function in a computer system performed by the apparatus.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of a processing apparatus having an unmanned automatic processing function in a computer system according to the present invention will be described as follows.

1 is a block diagram illustrating a power supply control apparatus according to the present invention having an automatic power-on function in a computer system, wherein the power supply control apparatus includes a microcomputer 102, a memory 104, an indicator 106, and an auxiliary power supply ( 108, the timer 122, the loading unit 124, the power supply 126, and the autorun program 128, shown in relation to the power control device, are components included in the computer system as hardware / software. For the description of the power supply control device, FIG. 1 shows only the necessary parts of the computer system.

The power control apparatus according to the present invention relates to an apparatus for turning on a computer at a designated time so that the computer system can be turned on at a designated time and a preset operation can be performed by the user even if the computer is turned off.

Specifically, with reference to FIG. 1, the microcomputer 102 in the power control device checks every hour from the timer 122 that is typically included in the computer system and counts the time, and the power-on time stored in the memory 104. It is compared with to determine whether it matches. Here, the power-on time of the computer system is stored in advance in the memory 104.

The microcomputer 102 generates a signal to turn on the power supply 126 of the computer system when the checked time and the power on time coincide, and if necessary, compare the present comparison to store the next power on time in the memory 104. The power-on time is erased from the memory 104. To this end, the memory 104 is preferably configured as an electrically erasable programmable ROM (EEPROM) capable of storing the power-on time or erasing the power-on time under the control of the microcomputer after the power supply 126 is turned on. Do.

When the power supply 126 of the computer system is turned on by the microcomputer 102, all computer booting processes are completed, and the automatic execution program 128 preset by the user is automatically driven. Here, the automatic execution program 128, for example, the scheduler (scheduler) is pre-set by the user the time information including the job to be automatically processed, and at least the start time and the power-on time of the job. When the automatic execution program 128 is automatically started, first, the time is checked from the timer 122. Then, the work already inputted is processed at that time.

That is, when the power of the computer system 126 is turned on, when the computer system automatically inputs a task to be processed by the computer system and the time information thereof, the power-on time is loaded by the loading unit 124. The microcomputer 102 is transmitted to the microcomputer 102, and the microcomputer 102 stores the power-on time in the memory 104. The loading unit 124 may use, for example, a communication port of a computer, and the microcomputer 102 may directly input a power-on time by using the automatic execution program 126.

Next, even if the computer system is powered off after the power-on time is stored in the memory 104, the power supply control apparatus of the present application remains in an enabled state. That is, as described above, the microcomputer 102 checks the time using the timer 122 included in the computer system, and compares the power-on time with the power-on time pre-stored in the memory 104. Repeat the operation of turning on).

In addition, the power supply control apparatus according to the present invention includes an indicator 106 for displaying the time from the timer 122 checked by the microcomputer 102 so that the user can see it. And an auxiliary power source 108 that supplies power to the microcomputer 102, memory 104, and indicator 106 regardless of whether the power source 126 is turned on or off in the computer system.

Hereinafter, a power control method for an automatic power on function in a computer system will be described with reference to the accompanying drawings.

2 is a flowchart of a preprocessing method for power control of a computer system, which is a method for recording a power-on time. First, it is determined whether the power-on time to be recorded is loaded (step 202). That is, referring to FIG. 1, it is determined whether the power-on time set in the automatic execution program 128 is loaded into the loading unit 102 by the microcomputer 102. If it is determined in step 202 that the power-on time is loaded, the process is repeated.

On the other hand, if it is determined that the power-on time is loaded, the power-on time is input by using an automatic execution program (step 204). That is, the automatic on time is input to the microcomputer 102 via the loading unit 102 in the automatic execution program. Here, in the automatic execution program, time information including an operation to be automatically processed and at least a start time and a power-on time of the operation are set in advance by the user, and the program performs the operation in accordance with the start of the operation. After operation 204, the input power-on time is stored (operation 206). Referring to FIG. 1, it is stored in the memory 104.

3 is a flowchart of a power control method according to the present invention for the automatic power-on function in a computer system, that is, a power control method performed by the microcomputer 102.

First, every time is checked from the timer included in the computer system (step 302). In addition, the inspected time is displayed for the user to view (step 304). Next, the checked time is compared with the power-on time of the prestored computer system, and it is determined whether or not it matches (step 306). Here, the pre-stored power-on time corresponds to the data stored in step 206 of FIG. 2. If the time checked in step 306 and the power-on time do not match, the process returns to step 302 again.

On the other hand, if the checked time and the power-on time coincide, a signal for turning on the power of the computer system is generated (step 308). When the power of the computer system is turned on by this signal, an autorun program preset by the user is driven. After operation 308, the power-on time is erased, and the operation proceeds to operation 302 again to repeat the above operation (operation 310).

As described above, the power supply control apparatus and method according to the present invention have the advantage of reducing the power consumption of the computer system and enabling the computer system to automatically process desired tasks at a specified time.
