In modern society, various electronic products including computers have become indispensable elements in daily life.

In particular, computers are the closest and always necessary tools for working at home and at work. Therefore, it is common practice to keep the computer powered on at all times so that it can be used immediately when needed.

However, since the computer is not always used at home or at work, it is a reality that the computer turns on even when not in use, which consumes a lot of power unnecessarily.

As the use of computers has become commonplace, power consumption by the power of computers has already become a social problem. Accordingly, activities to save the use of computers have been made. In addition, efforts have been made to technically reduce power consumption by such computers.

However, until now, technology has been introduced to save power by using only the presence or absence of computer, and the computer is more efficient in consideration of the user's computer usage situation such as the frequency and frequency of the computer user as well as the time when the user is away. No techniques have been introduced to conserve power.

For example, even when the computer user is away for a while, the user enters the standby mode immediately after leaving the computer and waits for four seconds to exit the power saving mode when the computer user returns to the seat. If the user resumes using the computer after entering the hibernation mode, the user may have to wait a longer time, which may cause inconvenience to the user who is away for a short time.

The present invention is to solve the above-described problems, an object of the present invention is to analyze the user's computer usage habits to save power step by step according to the possibility of using the computer, in particular, in consideration of the number of times and time away When the user is away from the computer, each power saving mode entry time is set in advance according to the user's computer usage habits so that the user can enter the power saving mode step by step so that the user's convenience and efficient power saving effect can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

1 is a schematic block diagram showing the concept of the present invention.

As shown, the power saving device 100 by the step-by-step mode conversion according to the present invention can be implemented in the form basically driven in the computer (30). However, the computer is just one example, and in the case of electronic products that require power saving, various applications are possible. In addition, although the driving in the computer 30 is described as an embodiment, the present invention is not limited thereto and may be implemented as one external device.

First, the present invention basically receives the user ID transmitted from the signal generation device 10 possessed by the computer user using the computer, it is determined that the computer user is currently using the computer within the computer 30 If the normal power is supplied and the user ID is not received, it is determined that the user of the computer is not in use and the computer is not used so that the power saving device 100 of the computer 30 can prevent unnecessary energy consumption of the computer. Switch the mode to power saving mode.

Specifically, the signal generator 10 transmits user ID information (hereinafter, referred to as "user ID") through the wireless communication network 20. The signal generator 10 may not only transmit a signal including the user ID at a predetermined time, that is, at a predetermined period or continuously, but also according to a request signal of the transceiver 101 or the power saving device 100. Can be transmitted.

However, the user ID may be applied in various formats when the user ID is information for identifying the user.

On the other hand, the wireless communication network 20 may be applied to various communication methods. For example, RF communication, Zigbee, Blue Pitcher, and the like can be used. As an example of RF communication, short range communication uses a frequency of 2.4 GHz band and long range band uses a frequency of 300 to 400 MHz band. In addition, it is possible to change the communication distance by adjusting the RF transmission power. Here, the RF transmitter may be used for the signal generator 10, and the RF receiver may be used as an information transmitter / receiver connected to the computer 30.

The communication distance for the power saving device 100 to recognize the user ID transmitted from the signal generator 10 needs to be appropriately selected according to the use environment.

Hereinafter, a configuration and method for saving power by stepwise mode conversion using the user ID transmitted from the signal generator 10 at a predetermined period or a request in the above environment will be described in detail.

FIG. 2 is a diagram showing the configuration of a power saving device by mode switching in stages according to the first embodiment of the present invention.

As shown, the power saving device by the step-by-step mode conversion (hereinafter referred to as the "power saving device") 100 is the control unit 110, the user authentication analyzer 120, the timer 131, the time setting unit 133 and It includes a step-by-step mode conversion unit 140.

Here, the user authentication analyzer 120 may include an analyzer 121 and a user authentication information DB 122.

However, in the following description of the present invention, when the user uses a computer, the power saving device 100 does not have a reason to operate. Therefore, the user ID that has been properly authenticated is based on the state that the user ID is continuously received. It will be explained on the premise of inconsistency or absence of generated user ID.

The power saving device 100 receives the user ID transmitted from the signal generation device 10 through the wireless communication network 20 through the transceiver 101.

Here, the transceiver 101 may be provided as a separate device for using the function of the transceiver provided in the computer 30 or for the power saving device 100.

The control unit 110 of the power saving device 100 not only receives the user ID in relation to the transceiver 101, but also transmits a user ID request message to the signal generator 10 through the transceiver 101 when necessary. In response, the user ID may be received. If the user ID is not received, the controller 110 may recognize that there is no reception of the user ID.

The controller 110 transmits the received user ID to the user authentication analyzer 120 and operates the timer 131 according to the analysis result of the user authentication analyzer 120.

Here, the user authentication analysis unit 120 is composed of an analysis unit 121 and the user authentication information DB 122, if the user ID is delivered, the analysis unit 121 is the user authentication information stored in the user authentication information DB 122 Output the analysis result by comparing with the passed user ID.

Here, the analysis result of the analysis unit 121 may output a result that the user ID and the user authentication information stored in the user authentication information DB 122 is the same or not.

However, the user authentication information DB 122 may store user authentication information for one user who is permitted to use, as well as user authentication information for a plurality of users.

When the matching user ID is received, the controller 100 may recognize that the user continues to use the computer, and thus does not operate the timer 131. In other words, the currently supplied power continues to be supplied and the conversion to a separate power saving mode is not performed.

Next, the controller 100 may operate the timer 131 when there is no user ID that matches the analysis result of the user authentication analyzer 120 or when no user ID is received at all.

In this case, when the timer 131 is operated, it may be determined that the user does not already intend to use the computer for a predetermined time, so that the step-by-step mode conversion unit 140 may immediately convert the power saving mode required for power saving.

On the other hand, even if the user is out of a certain area, it is possible to return to the original place in a short time to use the computer, so that it is possible to maintain the current state for a certain time without executing the power saving mode immediately.

This is normal for a certain period of time, even if there is no matching user ID, considering that the user can use the computer again within a certain period of time, and that more power may be consumed when switching to or waking from sleep mode. Keep your computer running In this case, it can be said that normal power is continuously supplied without changing the power saving mode.

When the controller 100 operates the timer 131, the timer 131 starts time counting.

Meanwhile, the time setting unit 133 sets the power saving mode entry time step by step after the timer 131 starts operation. That is, a predetermined power saving mode switching time is set step by step.

Specifically, the controller 100 operates the timer 131 and the timer 131 starts counting the time elapsed. When the count is started by the timer 131, until the count value reaches the power saving mode entry time set in the time setting unit 133, the same user ID or corresponding user ID as the user authentication information is not received or no information is received. If not, power saving mode will proceed.

At this time, the power saving mode entry proceeds step by step according to the power saving mode entry time preset for each power saving mode.

For example, the first power saving mode entry time can be set to 1 minute, the second power saving mode entry time to 5 minutes, and the third power saving mode entry time to 20 minutes. When the monitor is turned off, the second power saving mode is set to the standby mode, and the third power saving mode is set to the hibernation mode, a user ID corresponding to the user authentication information is not received until a minute after the timer 131 starts operation. If not, switch to monitor off mode.

Subsequently, if the user ID corresponding to the user authentication information is not received until 5 minutes and 20 minutes after the timer 131 is operated, the second power saving mode is switched to the standby mode. Switch to hibernation, a hibernation mode.

In other words, when a user ID corresponding to the user authentication information is not received over time, the user recognizes that the time when the user is not using the computer increases and converts the energy saving mode step by step.

On the other hand, if there is a keyboard, mouse, or power switch input in this process, the normal power is supplied from the power saving mode.

3 is a view showing a time setting unit for setting the power saving mode entry time according to the user's computer usage habits according to the present invention.

As illustrated, the time setting unit 133 sets a time corresponding to each of the first power saving mode, the second power saving mode, and the third power saving mode. In this case, the first power saving mode may be a monitor off mode, the second power saving mode may be a standby mode entering mode, and the third power saving mode may be a hibernation mode.

The time setting unit 133 may set each of 1 minute, 5 minutes, and 20 minutes from the time point at which the timer 131 starts to operate as a power saving mode switching time for each of the primary and secondary tertiary orders.

Therefore, when the authenticated user ID is not received or no information is received within each set time, the power saving mode is entered step by step every set time.

4 is a diagram illustrating a configuration of a power saving device by mode switching in stages according to a second embodiment of the present invention.

As shown, the power saving device 100 by the step-by-step mode conversion includes a control unit 110, a user authentication analysis unit 120, a user pattern analysis unit 130 and a step-by-step mode conversion unit 140.

Here, the user authentication analyzer 120 includes an analyzer 121 and a user authentication information DB 122, the user pattern analyzer 130 includes a timer 131 and a pattern analyzer 132, The stepwise mode converting unit 140 includes a mode selecting unit 141, a power saving mode DB 142, and a mode converting unit 143.

However, in the following description of the present invention, when the user uses a computer, the power saving device 100 does not have a reason to operate. Therefore, the user ID that has been properly authenticated is based on the state that the user ID is continuously received. It will be explained on the premise of inconsistency or absence of generated user ID.

The power saving device 100 receives the user ID transmitted from the signal generation device 10 through the wireless communication network 20 through the transceiver 101.

Here, the transceiver 101 may use the function of the transceiver provided in the computer 30 or may be provided as a separate device for the power saving device 100.

The control unit 110 of the power saving device 100 not only receives a user ID in relation to the transceiver 101, but also transmits a user ID request message to the signal generator 10 through the transceiver 101 when necessary. The transceiver 101 may transmit a user ID request message to the signal generator 10 by itself, and may receive a user ID in response thereto. If the user ID is not received, the controller 110 may recognize that there is no reception of the user ID.

The controller 110 transmits the received user ID to the user authentication analyzer 120 and generates a necessary signal according to the analysis result of the user authentication analyzer 120.

Here, the user authentication analysis unit 120 is composed of an analysis unit 121 and the user authentication information DB 122, if the user ID is delivered, the analysis unit 121 is the user authentication information stored in the user authentication information DB 122 Output the analysis result by comparing with the passed user ID.

Here, the analysis result of the analysis unit 121 may output a result that the user ID and the user authentication information stored in the user authentication information DB 122 is the same or not.

However, the user authentication information DB 122 may store user authentication information for one user who is permitted to use, as well as user authentication information for a plurality of users.

The control unit 110 generates a necessary control signal according to the analysis result of the user authentication analysis unit 120, where the required signal is a signal that a matching user ID is received, a signal that a matching user ID is not received, and a user ID. Can generate different control signals for which no is received at all.

When a matching user ID is received, the controller 100 may recognize that the user continues to use the computer, and thus may not output a separate control signal. In other words, the currently supplied power continues to be supplied and no additional power saving mode is converted.

Next, the controller 100 may generate a mode conversion signal as a control signal when there is no user ID that matches the analysis result of the user authentication analyzer 120 or when the user ID is not received at all.

Here, since the mode conversion signal can be seen that the user does not already intend to use the computer for a predetermined time, the mode conversion unit 140 can be converted directly to the mode required for power saving.

In consideration of the fact that the user can return to the original position and use the computer in a short time even when the user is out of a certain area, the control unit 100 can maintain the normal operation state of the computer for a predetermined time without changing the mode immediately. Can output a mode conversion signal.

In detail, the controller 110 may output the mode conversion preliminary signal and the timer operation signal as the mode conversion signal.

The mode conversion preliminary signal is a signal for maintaining the current computer operating state for a predetermined time in consideration of the fact that the user can use the computer again within a certain time even when there is no matching user ID. However, the mode switching preliminary signal may be generated separately by the controller 110 and may not be generated as any signal. At this time, the computer operates normally without conversion to the power saving mode.

Meanwhile, the timer operation signal generated by the controller 100 is transmitted to the user pattern analyzer 130.

The user pattern analyzer 130 analyzes the availability of the user's computer, etc. over time using the user's pattern, and outputs pattern information for converting modes according to the degree of the computer's availability.

The user pattern analyzer 130 includes a timer 131 and a pattern analyzer 132.

The timer 131 starts an operation according to the timer operation signal and generates a signal at a predetermined time. Here, the generated signal is generated at a predetermined period or a predetermined time interval from the time of the first operation, for example, may occur at a constant time interval such as 1 minute, 2 minutes, 3 minutes, of course, 30 seconds, 2 It may occur at predetermined time intervals such as minutes, 4 minutes, and the like.

If the same user ID as the user authentication information is not received within the signal generation time by the timer 131, the pattern analyzer 132 generates pattern information corresponding to the time point at which the signal is generated by the timer 131.

Here, the pattern information includes different pattern information according to the time sequence of the signal generated by the timer 131.

For example, if the user ID corresponding to the user authentication information is not received from the time when the timer operation signal occurs to 1 minute, the pattern analyzer 132 outputs the first pattern information, where the first pattern information is output. May be pattern information corresponding to the monitor off mode stored in the power saving mode DB 142 of the step-by-step mode conversion unit 140.

If the user ID corresponding to the user authentication information is not received until 2 or 3 minutes from the time when the operation signal is generated, the pattern analyzer 132 outputs the second pattern information and the third pattern information, where The second pattern information may be pattern information corresponding to the standby mode of the power saving mode DB 142, and the third pattern information may be pattern information corresponding to the maximum power saving mode of the power saving mode DB 142. In other words, when a user ID corresponding to user authentication information is not received over time, the likelihood of a user using a computer is gradually reduced, thereby recognizing a pattern and converting a power saving mode step by step.

However, the pattern information may be embodied in a specific signal or data form and may recognize only that there is no corresponding user ID at a specific point in time (1 minute, 2 minutes, 3 minutes, etc.). A signal or data to say is sufficient.

That is, the pattern analyzer 132 outputs pattern information necessary for each step according to a time determined by the timer 131.

The step-by-step mode converter 140 selects a power saving mode according to the mode conversion signal of the controller 110 or the user pattern information output from the user pattern analyzer 130 to convert the power supply mode.

Here, the step-by-step mode converter 140 includes a mode selector 141, a power saving mode DB 142, and a mode converter 143.

The mode selector 141 selects a power saving mode by using the user pattern information output from the user pattern analyzer 130.

The power saving mode DB 142 stores the power saving mode corresponding to the pattern information. In particular, information about each power saving mode is stored step by step according to a user's pattern.

For example, the power saving mode DB 142 may store a monitor off mode, a standby mode, and a hibernate mode. Here, the monitor off mode may correspond to the first pattern information, the standby mode may correspond to the second pattern information, and the maximum power saving mode may correspond to the third pattern information.

Finally, the mode converter 143 converts to the energy saving mode selected by the mode selector 141.

That is, the mode converter 143 may turn off the computer monitor, enter the standby state, or may enter the hibernation mode.

5 is a diagram illustrating a power saving method by mode conversion in stages according to a third embodiment of the present invention.

As shown, the power saving method by the step-by-step mode conversion, first, receives the user ID information from the signal generator 10 carried by the user (S10) Here, the reception of the user ID information is a signal generator ( The method may be performed by the method 10 for transmitting the user ID or the method for transmitting the user ID by the signal generator 10 in response to the user ID request signal from the power saving device 100 or the transceiver 101.

After receiving the user ID information, it is determined whether the user ID is normally received (S20). If it is determined that the user ID is not received, the timer operation is performed.

On the other hand, after receiving the user ID information, the predetermined user authentication information and the user ID information is compared (S30), and it is analyzed whether the same user ID information exists (S40).

If the user ID information corresponding to the previously stored user authentication information exists in the received user ID information, the energy saving mode is canceled and the process returns to the first step of receiving the user ID information (S50).

As a result of the determination, when the user ID information corresponding to the user authentication information stored in advance does not exist in the received user ID information, the timer operation is performed (S60).

On the other hand, after the timer operates, if there is no user ID corresponding to the user authentication information, the count value continues to increase, and it is determined whether the count value reaches the preset power saving mode entry time (S70).

As a result of the determination, when the counted value does not reach the preset power saving mode entry time, it is determined that the computer user is using the computer, thereby maintaining the normal operation state of the computer and returning to the user ID information receiving step (S10). .

As a result, when the user ID is not confirmed within the preset power saving mode entry time and the counted value reaches the preset power saving mode entry time, the power saving mode is switched to the power saving mode step by step according to the power saving mode entry time set for each power saving mode. (S80)

For example, it is checked whether a user ID corresponding to the user authentication information is received at a predetermined time interval or at a predetermined power saving mode entry time for each power saving mode after the timer operates. First, when the user ID corresponding to the user authentication information DB is not received until the preset first power saving mode entry time is reached, the mode is switched to the first power saving mode, that is, the monitor is turned off. After entering the first power saving mode, if the user ID corresponding to the user authentication information DB is not received continuously until the preset second power saving mode entry time, it is converted into the second power saving mode, that is, the standby mode. Finally, if the user ID corresponding to the user authentication information DB does not exist until the third power saving mode entry time after the standby mode conversion, the mode is converted into the third power saving mode, that is, the hibernation mode.

However, when changing the power saving mode in the above steps, if there is an external input such as a mouse, keyboard, power switch or the received user ID corresponds to the user authentication information DB, the power saving mode is canceled and normal power supply, that is, normal computer operation. This is done.

On the other hand, the power saving method by the step-by-step mode conversion described above can be implemented by a computer-readable recording medium recording a program.

The invention is not to be limited by the foregoing embodiments and the accompanying drawings, but should be construed by the appended claims. In addition, it will be apparent to those skilled in the art that various forms of substitution, modification, and alteration are possible within the scope of the present invention without departing from the technical spirit of the present invention.
