Description

Computer energy saving system based on power usage pattern identification}

The present invention relates to a computer energy saving system based on identifying power usage patterns. A computer energy saving system capable of saving energy by lowering power consumption of a computer by controlling a power saving time when a computer enters a power saving mode.

Devices such as desktop computers and portable computers, abbreviated PCs, operate by combining a body that performs calculations and a monitor for displaying calculation results. These PCs are used so many times that it is difficult to count the number of PCs, from one to many, in restaurants and homes as well as in companies where people work. Computers are already popular enough to say that it is extremely rare to have a PC at home or at work.

Recently, as society is industrialized and advanced, the use of PCs is gradually increasing. In particular, when performing specialized tasks or tasks requiring numerous calculations, it is necessary to connect high-spec PCs or multiple PCs in parallel.

Accordingly, in modern society, power consumed by PCs tends to gradually increase, and many methods for reducing power consumption or standby power wasted by PCs are being studied.

As a prior art for this, Korea Patent Registration No. 10-1769707 discloses 'PC standby power remote monitoring control and control method and device'.

The PC standby power control apparatus according to the prior art includes a server capable of remotely monitoring client PCs and controlling client PCs in response to monitoring results in order to reduce power consumption of client PCs and client PCs, When the power consumption wasted by the client PCs is less than a pre-specified power consumption threshold, the server continues to maintain the time required to switch to the standby mode, and if the wasted power is greater than the pre-specified power consumption threshold, the server continues to standby. It can be controlled to reduce the time taken to switch modes.

Therefore, according to the prior art, unnecessary energy waste can be reduced by collectively controlling the time of entering the sleep mode and the standby mode of the client PC in the server.

However, since this prior art only identifies power consumption without identifying the usage pattern of each PC, when using a program with high power consumption, for example, a graphic program that requires high specifications, depending on the use of a high-specification program of a specific client PC Since the standby mode transition speed can be fully controlled, there is a limitation in that only collective control is performed without control tailored to individual PCs.

Therefore, in order to solve the above problems, it is necessary to develop a new and advanced computer energy saving system that provides energy saving effect by identifying the power usage pattern of individual computers and controlling the power saving mode transition time of the computer based on this. This situation is emerging.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing indicate like elements.

1 is a conceptual diagram of a computer.

Referring to FIG. 1, the computer 10 may include a main body 11 and a monitor 12, and among them, a central processing unit (CPU), a PCH on the motherboard of the main body 11 (Platform Controller Hub) is mounted or embedded. Here, the motherboard is also referred to as a main board, and means a board on which basic circuits and parts are embedded and mounted in the computer 10 . Components of the computer 10 included in the motherboard include a central processing unit (CPU), a microprocessor, a coprocessor, a memory, a BIOS, an expansion slot, an access circuit, a platform controller hub, and the like.

Here, a graphics card (PCI-E Graphics) and system memory, DDR3 memory, are connected to the central processing unit. In addition, the integrated display unit and peripherals unit are connected to the platform controller hub (PCH).

The central processing unit is a device that controls the entire system of the computer 10, and serves to control and adjust a series of processes that receive and process data from various input devices and send the result to an output device. This central processing unit includes a graphic driver (iGFX) for driving a graphic card and an Integrated Management Controller (IMC) for driving a system memory.

Furthermore, these platform controller hubs include displays, input method editors (IMEs), input/output controllers, and real-time clock generators.

On the other hand, the motherboard is equipped with a BIOS (Basic Input/Output System), a small operating system responsible for driving and operating the CPU and PCH. This BIOS controls system input voltage and current, communicates with each device, and sets settings. It plays a role in defining and operating values.

The computer energy saving system based on identifying the power usage pattern of the present invention learns the power consumption pattern including the usage time during which the computer 10 is being used and the power usage during the usage time, and determines the corresponding power consumption pattern. After calculating the corrected power saving time by correcting the time for switching the computer 10 to the power saving mode, the computer 10 performs a function of switching the standby computer 10 to the power saving mode by applying the corrected power saving time.

Learning the power consumption pattern of the computer 10, calculating the corrected power saving time through the learning of the power consumption pattern, and controlling the transition to the standby mode through the application of the corrected power saving time can be implemented through the central processing unit provided in the computer 10. .

Furthermore, the power saving mode conversion control of the present invention can be performed in conjunction with various parts connected to the computer 10, that is, peripheral devices, and this also analyzes and processes input data through the peripheral devices via the central processing unit. there is.

2 is a block diagram showing the detailed configuration of the system of the present invention.

Referring to FIG. 2 , the computer energy saving system based on identifying the power usage pattern of the present invention may include a power saving time setting module 100, a learning module 200, a power saving time correction module, and an energy saving execution module. can

The power saving time setting module 100 performs a function of setting a basic power saving time, which is a time to convert the standby computer 10 to power saving mode.

Here, standby means that the computer 10 is not in use, and determination that the computer 10 is standby determines the input device provided in the computer 10, that is, the mouse, keyboard, touch screen, This refers to the time during which no signals or key inputs are made through a tablet or the like.

At this time, if a signal or key input is not received during the predetermined standby state determination time, it may be determined as in standby. Here, the standby state determination time is not limited to values that can be set, such as 10 seconds, 30 seconds, and 60 seconds.

In this way, when the standby state is maintained for as long as the transition time, the corresponding computer 10 may be switched to the power save mode. Here, the power saving mode may be similar to the conventional standby mode.

Therefore, during such a power saving mode operation, a screen saver or the like may be output through the monitor 12 connected to the computer 10, and when switching to the power saving mode, a hard disk and a CD-ROM drive excluding the main board and memory may be displayed. Since all unused devices are turned off, power consumption of the computer 10 can be reduced.

For example, if the default sleep time is 10 minutes, the computer 10 that has been on standby for 10 minutes is converted to sleep mode. It can be set to minutes, 10 minutes, 30 minutes, or 1 hour. There is no limit to the setting range of the basic power saving time.

However, preferably, the basic power saving time is longer than the above-described standby state determination time, and as described above, the standby state determination time may be 10 seconds, 30 seconds, 60 seconds, etc., and the basic power saving time is 5 minutes, It can be 10 minutes, 30 minutes, 1 hour, etc.

3 is a conceptual diagram illustrating an example of power usage of the process of the present invention.

Referring to FIG. 3 together with FIG. 2 , the learning module 200 basically includes the pattern identification unit 210 and measures the usage time, which is the time the computer 10 is using, and the power consumption during the usage time. It performs the function of identifying the power consumption pattern including

In the above description, the time during which the computer 10 is being used, that is, the time when signals or key inputs are continuously occurring, is identified as the usage time, where signals or key inputs do not occur to exceed the above-mentioned standby state determination time. In this case, it is determined that the use of the computer 10 is stopped and it is determined that the computer 10 enters a standby state. At this time, the duration of the standby state is the standby time, and when a signal or key input is generated again through the input means of the computer 10, it is judged as the end of the standby state and the start of the use state, and the use time is re-counted will happen

For example, the time between the end of the first use time and the start of the second use time is the standby time. Here, since there may be a plurality of use times and standby times, the time between the first and second use times will be referred to as the first standby time, and the time between the second and third use times will be referred to as the second standby time.

Therefore, the pattern identification unit 210 of the learning module 200 determines the power consumption pattern of the computer 10 based on determining the length of each use time and standby time.

Furthermore, when the length of the use time and the length of the standby time are determined, the amount of power used during the use time is determined. That is, the amount of power used during the usage time is determined. In this case, the determination of the amount of power is to determine the amount of power consumed by the computer 10 during the usage time, and the unit of the amount of power usage may be Wh or KWh.

Here, when a plurality of usage times are identified, for example, when the first and second usage times are respectively identified, the power usage for each of the first and second usage times is separately identified, and thus, the power usage during a specific usage time is identified. can be figured out.

Accordingly, the usage time during which the computer is being used and the power consumption during the usage time are identified as power consumption patterns, and the thus identified power consumption patterns may be used to calculate the corrected power saving time.

Furthermore, the pattern detection unit 210 of the learning module 200 may further include the number of processes the computer is running during the usage time in the power consumption pattern. In other words, the power consumption pattern may include usage time, power usage during the usage time, and the number of processes running through the computer during the usage time.

Here, if the number of processes is large and the power usage is high, a large amount of processes are running and the power usage is high, and if there are few processes but the power usage is high, the power usage of individual processes is high (high load). it is possible to understand

Furthermore, in determining the number of running processes, more preferably, it is also possible to determine the name of the running process, and furthermore, the memory allocation amount, cpu allocation amount, and disk allocation amount of each process together.

The power saving time correction module 300 sets the corrected power saving time by correcting the basic power saving time according to the power consumption pattern identified through the pattern identification unit 210 of the above-described learning module 200, preferably power consumption. As the use time identified through the pattern is short and the power consumption is high, the correction power saving time is shortened. Here, the short usage time means that the length of the average usage time on the power consumption pattern is short. Or it means that the maximum value of the length of use time is short.

In other words, a short usage time means that a state that is not in use (standby) but is not switched to power saving mode lasts for a long time. It means that the state of being left in a state of high power consumption is long.

Therefore, when the use time is short, correction is performed so that the corrected power saving time is shorter than the basic power saving time, so that energy can be saved, and it is possible to prevent being left without converting to a power saving mode in an unused state.

Furthermore, since high power usage means that energy is excessively consumed, energy saving can be performed by performing correction so that the corrected power saving time is shorter than the basic power saving time when the power usage is high.

In addition, when the number of running processes is large, power consumption tends to be high. Therefore, when the number of processes is large, energy saving can be performed by performing correction so that the calibrated power saving time is shorter than the basic power saving time. However, if there are few processes but high power usage, it is possible to identify individual processes as having high power usage (high load), so even if the number of processes is small, if the power usage is high, the compensation sleep time is compensated to be shorter than the basic sleep time. By doing so, it is possible to perform energy saving.

However, when the number of processes is small and the power consumption is very low, the calibrated sleep time can be calibrated similarly to the basic sleep time because the number of tasks being performed through the computer is small and it can be determined that the power save is sufficiently performed.

Here, if the number of processes is small, the power consumption is very low, and the usage time is short, the calibrated power saving time may be slightly shorter than the basic power saving time, and if the number of processes is small, the power usage is very low, and the usage time is relatively long, There may be little difference between the calibrated sleep time and the default sleep time.

Furthermore, when the number of processes is large and the power consumption is very low, the power consumption may be judged to be low even though various tasks are performed through the computer, so the calibrated sleep time should be longer than the default sleep time so that the running processes can be sufficiently completed. can

Here, if the number of processes is large, the power consumption is very low, and the usage time is long, various processes are performed for a long time, but the power consumption is low. If the number of processes is large, the power usage is very low, and the usage time is short, the process is performed for a short time but the power usage is low, so the calibrated sleep time can be similar to or slightly longer than the default sleep time. there is.

The energy saving performance module 400 includes a mode switching unit 410 and performs a function of converting a standby computer to a power saving mode by applying a corrected power saving time. Therefore, during the corrected power saving time, the standby computer 10 is converted into a power saving mode to save power consumption, that is, energy.

At this time, when switching to the power saving mode, a screen saver or the like may be output through the monitor 12 connected to the computer 10 as described above, and when switching to the power saving mode, the hard disk and CD- Power consumption of the computer 10 can be reduced since all unused devices such as a ROM drive are turned off.

According to the computer energy saving system based on grasping the power usage pattern of the present invention, the power consumption pattern including the usage time of the computer 10, the power usage during the usage time, and the number of processes running during the usage time is learned. Based on this, by correcting the time for the computer 10 to switch to the power saving mode in which power saving is performed, the computer 10 can be switched to the power saving mode according to the power consumption pattern, taking into account the efficiency of use of the computer At the same time, by preventing energy waste, it is possible to reduce power consumption of the computer 10 and save energy.

In addition, as described above, it is said that the pattern identification unit 210 of the learning module 200 can determine the number of processes running through the computer 10 during the usage time. The dividing unit 220 may be further included to divide the running process into an essential process and a standby process.

Here, the essential process refers to a process that actually needs to be processed or has a high memory and disk allocation among running processes, and means a process with high importance among running processes, and a standby process is not actually processed but is unnecessary. Processes that are running properly or have low memory and disk quotas.

In addition, there is no limitation on the method of distinguishing the essential process from the standby process, but as another preferred embodiment, a process usage pattern of the corresponding computer 10 is analyzed and a process that is frequently used, that is, frequently executed, is classified as an essential process. In the case of a process that is not frequently executed, it is also possible to classify it as a standby process.

That is, a process with a high number of executions may be compared as an essential process, and a process with a low number of executions may be classified as a standby process by comparing execution counts of each process during a predetermined analysis period from the past to the present. Here, the analysis period is a value that can be set by the system administrator and is not limited in its range.

Therefore, through the standby process separator 220 included in the learning module 200, the running process can be divided into an essential process and a standby process. can be said to be

In addition, if the essential process and the standby process are distinguished through the detailed configuration of the learning module 200 in this way, the standby deactivation processing unit 420 that may be included in the energy saving performance module 400 switches the computer 10 to power saving mode. At this time, the waiting process can be deactivated.

Therefore, when the computer 10 is switched to the power saving mode, all standby processes except essential processes can be deactivated, so that the power consumption saving effect through the energy saving system of the present invention can be further enhanced.

In addition, as in the above description, it is said that the number of running processes can be identified through the learning module 200. Here, the power consumption of individual processes that are running through the process identification unit 230 that can be included in the learning module 200 It is also possible to figure out

In more detail, the process identification unit 230 performs a function of identifying individual power consumption, i.e., power consumption of each process running through the computer 10 during the usage time.

For example, if processes 1,2,3 are running, process 1's individual usage during usage time is 3 Wh, process 2's individual usage during usage time is 2 Wh, and process 3's individual usage during usage time is 2 Wh. The power consumption by process is identified as 7Wh, and the individual consumption of each process 1, 2, and 3 can be identified as 3Wh, 2Wh, and 2Wh.

In this way, when the individual usage amount is identified, the energy saving execution module 400 further includes an individual deactivation processing unit 430 to compare the individual usage amount with a preset reference individual power usage amount and deactivate a process exceeding the reference individual power usage amount. function can be provided.

In other words, the individual usage of each running process is compared with the reference individual power usage, and processes indicating individual usage exceeding the reference individual power usage are deactivated. Here, the reference individual power consumption is a value that can be set by a system manager, and is based on not limiting the range of the value.

Therefore, the energy saving effect for the computer 10 can be increased by deactivating processes having individual usage exceeding the standard individual power usage, that is, processes that may cause excessive power usage and thus overload the computer 10. can

In addition, the learning module 200 can classify a plurality of processes being executed through the computer 10 into essential processes and additional processes. To this end, the learning module 200 may include an additional process separator 240. .

The additional process separator 240 provides a function of classifying a plurality of processes into essential processes and additional processes, where the essential process denotes a process of high importance and the additional process denotes a process of low importance. Here, the distinction between the essential process and the additional process may be made based on the process execution record of the corresponding computer 10. Among all processes, a process with a high execution frequency may be classified as an important process, and a process with a low execution frequency may be classified as an additional process. Alternatively, it is possible to directly classify essential processes and additional processes by the system administrator, or to have the classification criteria set by the system administrator.

Therefore, it is possible to classify a plurality of processes into an essential process and an additional process according to a classification standard set by a system manager or a classification standard that can be automatically set in the system, such as the above-described execution frequency.

Furthermore, when the classification of essential processes and additional processes is performed in this way, the energy saving performance module 400 can deactivate processes classified according to power consumption step by step. To this end, the energy saving performance module 400 performs 1 It may include a primary deactivation processing unit 440 and a secondary deactivation processing unit 450.

The primary deactivation processing unit 440 compares the power usage at the time of calculation with a preset reference total power usage, and performs a function of disabling the additional process when the power usage exceeds the reference total power usage.

In other words, when the power usage exceeds the standard total power usage, it is determined that power overload has occurred and an additional process of relatively low importance is deactivated so that energy can be primarily saved. Here, the reference total power usage is a value that can be set by a system manager, and is based on not limiting the range of the value.

Here, when deactivating the additional processes, all processes set as additional processes may be simultaneously deactivated, or sequential deactivation may occur in order of higher or lower power usage among processes included in the additional processes.

Next, the secondary deactivation processing unit 450 compares the power usage after the deactivation of the additional process with the reference total power usage, and performs a function of disabling the essential process when the reference total power usage is exceeded.

When the additional process is deactivated by the primary deactivation processing unit 440, it is common that energy consumption, that is, power consumption decreases according to the deactivation. Exceeding ? means that power consumption is excessive even though the additional process is deactivated.

Therefore, in this case, it is possible to increase the energy saving effect for the computer 10 by additionally deactivating the essential process. can proceed

Here, it is possible to deactivate all of the plurality of processes included in the essential process at once, but preferably, it is also possible to sequentially deactivate the processes included in the essential process in order of high power consumption or in the order of low power consumption. In the case of a process, since it means a process with a relatively high importance, it can be said that it is more desirable to sequentially inactivate a process of low power consumption (process with a relatively low workload) among the processes belonging to the essential process.

Therefore, through this, it is possible to perform additional energy saving through process deactivation based on power consumption, but at this time, the importance of processes can be classified and deactivation can be performed sequentially, starting with processes with low importance, resulting in energy saving and efficient process It has the effect of being able to perform execution control.

4 is a graph showing power consumption for each section of the present invention.

Referring to FIG. 4, the learning module 200 of the present invention includes a past learning execution unit 250 and shows the change in power consumption according to the use time of the computer 10 driven in the past as a graph. It is possible to create and store data.

Here, the x-axis is the usage time, and the y-axis is the power usage. Here, the usage time may be divided into a plurality of sections. At this time, as long as the criterion for sectioning is preferably Wh or KWh, it is possible to compare and process the power usage for each section having a length of 1 hour by sectioning in units of 1 hour.

That is, the usage time of the computer 10 driven in the past is divided into time units such as 1 hour as in the above example, and divided into a plurality of sections, and the power consumption for each section is displayed in a graph such as a bar graph or a line graph. is to city

The graph generated in this way may be stored as learning data in a separate DB, and for this purpose, the learning data may be stored in the storage device in conjunction with a storage device such as a memory provided in the computer 10.

Furthermore, the data generated in this way can be stored hourly, daily, weekly, and monthly. Therefore, learning data refers to a plurality of data representing changes in power consumption during past usage time, and such learning data It can be said to be stored and learning about changes in power usage by section during the past usage time.

In the graph example of FIG. 4, it is shown that the length of the section is set to 1 hour, and the power consumption for each section is identified and displayed as a bar graph value.

5 is a graph showing an overpower usage period of the present invention.

In addition, when the graph is grasped in this way, the overpower determination unit 260, which may be included in the learning module 200, identifies a section in which power consumption exceeding the reference total power consumption continuously appears in the graph, as shown in FIG. Performs the function of recognizing the overpower use section.

In other words, by comparing the power usage value shown in the graph with the reference total power usage that can be set by the system manager as described above, a section in which the power usage exceeds the reference total power usage is identified.

Here, an example of identifying a section in which power usage exceeding the standard total power usage continuously appears as an overpower usage section can be identified with reference to FIG. 5 . The length of the overpower usage period may be equal to or greater than the length of the above-mentioned period.

As an example, if there is one section in which power usage exceeding the standard total power consumption continuously appears, the length of the overpower usage section is the same as the length of the above-mentioned section (1 hour as an example), but if it exceeds the standard total power usage When there are 2 sections in which the power consumption is continuously appearing, the length of the overpower usage section is 2 hours, which may be longer than the length of the above-mentioned section.

Therefore, when power usage exceeding the standard total power usage appears continuously, it can be said that the corresponding section is integrated and identified as an overpower usage section.

The adjustment time determination unit 270, which may be included in the learning module 200, compares the long and short lengths of a plurality of identified overpower usage periods, designates the longest overpower usage period as the maximum usage period, and determines the maximum usage period. Provides a function to determine the length of time as the adjustment time.

For example, if there are a plurality of overpower usage intervals, since the lengths of the overpower usage intervals may be different from each other, the long and short periods of the overpower usage intervals are compared and the overpower usage interval having the longest length is designated as the maximum usage interval. Furthermore, the time length of the maximum use section is identified as the adjustment time.

Therefore, the adjustment time is the length of time during which the power usage is excessively maintained, and therefore, it can be inferred that the process usage during the adjustment time is high, so that it is difficult to grasp even the time when the amount of work performed through the computer 10 is high. possible.

In this way, when the adjustment time is identified, it is possible to sequentially deactivate a plurality of additional processes during the adjustment time when the power usage at the time of calculation is compared with the preset reference total power usage and exceeds the reference total power usage.

As described above, the length of the adjustment time may mean a time when the amount of work performed through the computer 10 is large. In other words, since the length of the adjustment time means a time when the computer 10 has a large amount of work, that is, a time when there are many processes to be processed, the length at which excessive power usage is expected to occur may be the adjustment time.

Therefore, during this adjustment time, a plurality of additional processes are sequentially deactivated, and among the processes included in the additional processes, sequential inactivation occurs in order of higher or lower power consumption.

Therefore, rather than abrupt termination of the process, sequential termination can be performed during the adjustment time, so that computer users can minimize the inconvenience caused by the sudden termination of the process and enjoy the energy saving effect of lowering power consumption. there is
As described above, although the configuration and operation of the computer energy saving system based on the identification of the power usage pattern according to the present invention are expressed in the above description and drawings, this is merely an example and the spirit of the present invention is not reflected in the above description and drawings. It is not limited, and various changes and modifications are possible within a range that does not deviate from the technical spirit of the present invention.
