Description

Information processing apparatus, power control program selection method, selection program, and information processing terminal

The present invention relates to an information processing apparatus, a power control program selection method, a selection program, and an information processing terminal.

In recent years, in response to heightened awareness of power saving and power saving, measures for power saving setting and power saving efforts have been implemented.
Especially in power saving efforts, in order to avoid excessive power consumption during the daytime in the summer, peak shift / cut of power usage (a part of daytime power consumption is shifted to nighttime power, resulting in the peak of maximum power consumption). Measures to achieve the goal of shifting the period of time and suppressing the peak itself) are important.

For this reason, in a laptop personal computer (notebook PC), it contributes to peak shift / cut, so peak shift / cut time zone (time zone specified by power usage restriction or power saving time zone uniquely defined by each organization) There is a growing momentum to use the power charged in the built-in battery.

Until now, notebook PC batteries have been used for the purpose of operating a computer as a power source when power cannot be obtained from a commercial power source or when there is no commercial power source. Although power can be obtained from a commercial power source, there was no concept of using power from a battery in order to reduce power consumption from the commercial power source at the present time.

For this reason, in order to reduce the power consumption from the commercial power source, in order to cut off the power inflow from the commercial power source, unplug the power plug of the commercial power system and monitor the remaining battery level manually. Operation is performed in which power is supplied and the power plug is connected to the commercial power source again before the remaining battery power runs out.

Or, dedicated software is installed in the notebook PC, and the battery and commercial power source are switched during a predetermined time period.

This software is a program in which the time to switch between battery and commercial power is embedded as a fixed value, and when the specified time comes, power supply from the commercial power and charging of the battery are stopped and the battery is charged. Start using the power. This software uses the battery power until the battery charge capacity is exhausted or the end time is reached.

During this time, even if the battery runs out on the way, the battery is not charged and only the power necessary for operation is supplied from the commercial power supply.

In manual power switching, the power plug must be manually connected and disconnected to switch between battery and commercial power. The user of the notebook PC does not always remove the power plug from the insertion port in order to switch from the commercial power supply to the battery during the peak shift / cut time period. For this reason, there is a problem that the user does not execute switching because it is troublesome to forget to switch or to insert / remove the power plug.

In addition, when the battery charge decreases during the peak shift / cut time period and the power plug is inserted, it is necessary to supply the power for operating the notebook PC and the power for charging the battery. There is a problem of increasing.

Furthermore, if there is a plan to operate with battery power after the peak shift / cut time period, it is necessary to leave the battery power amount in anticipation of the time to operate the notebook PC using the battery. The problem is that it is impossible to estimate the amount of battery charge required for this, monitor the remaining battery level, and manually switch between battery and commercial power when the remaining battery level reaches the required threshold. There is.

When switching power with software, the time is fixed in the software program and switching between battery and commercial power is controlled, so the battery charge is used up during the peak shift and cut time periods, but the peak shift cannot be performed because the battery cannot be charged.・ After the cut time, the battery can not be used. Alternatively, the battery charge is not used up, but the charge is significantly reduced, and the battery is inoperable.

For this reason, there is a problem that it becomes impossible to use the notebook PC in a place where there is no commercial power supply after the peak shift / cut time period.

In the conventional method, there is a problem that the battery and the commercial power source cannot be finely switched, and there is a problem that the efficient switching considering the past use situation and the future schedule cannot be performed.

An object of the present invention is to perform power control in consideration of the usage status of an information processing terminal such as a notebook PC.

The information processing apparatus according to the embodiment includes a storage unit and a processing unit.
The storage unit stores operation result information in which past usage states of the information processing terminal are described, and a plurality of programs that control switching of the power source of the information processing terminal.

The processing unit selects a program suitable for the usage status of the information processing terminal from the plurality of programs based on the operation result information, and transmits the selected program to the information processing terminal.

The information processing terminal according to the embodiment includes a battery, a storage unit, an information collection unit, and a control unit.

The battery supplies power to the information processing terminal. The storage unit stores operation result information in which a past use state of the information processing terminal is described.

FIG. 5 is a configuration diagram of the management server according to the embodiment.
The management server 301 includes an information collection unit 311, an analysis unit 321, a program selection unit 331, a program change unit 341, an instruction unit 351, and a storage unit 361.

The information collecting unit 311 stores the result DB 253-i received from the notebook PC 201-i in the storage unit 361 as the result DB 263-i. Further, the information collecting unit 311 stores the configuration information 254-i received from the notebook PC 201-i in the storage unit 361 as the configuration information 364-i.

The analysis unit 321 refers to the result DB 363-i, analyzes the usage status of the notebook PC 201-i, and notifies the program selection unit 331 of the analysis result.

The program selection unit 331 selects a power control program 362 suitable for the usage status of the notebook PC 201-i from the power control program 362 based on the analysis result. The program selection unit 331 transmits the selected power supply control program 362 to the notebook PC 201-i.

The program change unit 341 modifies the power control program 362. As a result, the operation of the power supply control program 362 is changed. For example, when the battery 241 is scheduled to be used from the schedule information, and the amount of charge of the battery required at that time is determined to be 70% of the full charge, the notebook PC actually has the battery 241 fully charged. If it is assumed that the battery is used only, the software program is determined to make the required battery charge amount 50%.

The instruction unit 351 instructs the notebook PC 201 to switch the power source between the battery 241 and the commercial power source.

The storage unit 361 is a storage device that stores data. The storage unit is, for example, a magnetic disk device or a semiconductor storage device.

The storage unit 361 stores a power control program 362-j (j = 1 to 3), a performance DB 363-i, and configuration information 364-i.

The power supply control program 362 is a program that operates on the notebook PC 201 and performs power control of the notebook PC 201. In the embodiment, three power supply control programs 362 are used. The features of each power control program 362 will be described later.

The performance DB 363-i is information indicating the operating status of the notebook PC 201-i. The contents of the result DB 363-i are the same as the configuration information 254-i.

The configuration information 364-i is information indicating the configuration and performance of the notebook PC 201-i. The contents of the configuration information 364-i are the same as the configuration information 254-i.

Here, the power supply control program 362-j (j = 1 to 3) used in the embodiment will be described.
FIG. 6 is a diagram showing the characteristics of each power supply control program.

In the embodiment, three patterns of power supply control programs 362-j are prepared.
In the embodiment, power supply control programs 362-1 to 362-3 are referred to as day type 1, day type 2, and night type, respectively.

As described above, one of the power supply control programs 362 suitable for the notebook PC 201 is selected based on the usage status of the notebook PC 201, and is installed and executed in the notebook PC 201.

The situation in which the daytime type 1, daytime type 2 and night type power supply control programs are selected and the characteristics of the basic operation are as follows.
(1) Daytime type 1
The day type 1 is used when the notebook PC 201 operates in the daytime, and operation using only the battery occurs during a business trip or the like. The daytime type 1 performs power saving operation during the power saving time (peak shift time), but considers the battery operation schedule and operates to leave the battery charge amount according to the use schedule. The day type 1 transmits the result DB 253 periodically (every hour) to the management server 301 in order to correct the difference between the battery remaining amount prediction based on the schedule and the result value. The management server 301 is updated to a day type 1 program optimized for the notebook PC 201.

(2) Daytime type 2
The day type 2 is used when the notebook PC 201 operates in the daytime but there is almost no situation that requires battery operation. For this reason, the battery will be actively used during power saving time.

Daytime 2 is basically controlled to use the battery 241 during the peak shift / cut time period. For regular usage, the transmission of the results DB 253 to the management server 301 is performed once every 24 hours at the time of activation. Therefore, the update frequency of the day type 2 program is low.

(3) Night type The night type is used when the notebook PC 201 operates at night. There is almost no situation (business trip or the like) in which the notebook PC 201 operates on a battery, and the necessity and possibility of operation with a battery are low because the power demand is marginal at night. There is a possibility that the notebook PC 201 uses a battery for power saving operation time (for example, winter morning and evening time zones) to support power saving operation. The night type has sufficient power supply and does not need to actively control the power supply of the notebook PC 201. For this reason, the transmission of the results DB 253 to the management server 301 is performed once every 24 hours at the time of activation. Therefore, the frequency of updating night type programs is low.

FIG. 7 is a flowchart of processing of the notebook PC according to the embodiment.
In step S501, the control unit 211 checks whether communication with the management server 301 is possible. If communication with the management server 301 is possible, control proceeds to step S502. If communication with the management server 301 is not possible, control proceeds to step S508.

In step S502, the control unit 211 determines whether or not a battery use instruction has been received from the management server 301. If a battery usage instruction has been received, control proceeds to step S507. If a battery usage instruction has not been received, control proceeds to step S503.

In step S503, the control unit 211 transmits the result DB 253 to the management server 301.

In step S504, the control unit 211 receives the power control program 362 from the management server 301, and whether the received power control program 362 is a new program (that is, is different from the currently installed power control program 252). judge. Even if the program has the same pattern, if the program is changed, it is determined that the program is a new program. If it is a new program, the control proceeds to step S505, and if it is not a new program, the control proceeds to step S506. The control unit 211 stores the received power control program 362 in the storage unit 251 as the power control program 252.

In step S505, the control unit 211 installs the power control program 252 in the notebook PC 201.

In step S506, the control unit 211 determines whether or not a notification of canceling the battery use instruction has been received from the management server 301. When the notification of canceling the battery use instruction is received, the control proceeds to step S508, and when the notification of canceling the battery use instruction is not received, the control proceeds to step S507.

In step S507, the control unit 211 uses the battery 241 as a power source.

In step S508, the control unit 211 executes the installed power control program 252.

In step S509, the information collection unit 221 records the usage status information of the notebook PC 201 such as the remaining battery level and the power usage time in the performance DB 253.

FIG. 8 is a flowchart of processing of the management server according to the embodiment.
In step S601, the instruction unit 351 refers to the notification from the smart meter 401 and determines whether or not the power consumption in the organization (the total power used by the information processing apparatuses in the organization) exceeds a threshold value. If the power consumption exceeds the threshold, the control proceeds to step S602, and if the power consumption is less than or equal to the threshold, the control proceeds to step S603. Note that the range of the tissue and the threshold are determined in advance.

In step S602, the instruction unit 351 transmits a battery use instruction for instructing the use of the battery 241 to the notebook PC 201.

In step S603, the information collection unit 311 checks whether communication with the notebook PC 201 is possible. If communication with the notebook PC 201 is possible, control proceeds to step S604. If communication with the notebook PC 201 is not possible, the process ends.

In step S604, the information collection unit 311 receives the result DB 253 from the notebook PC 201, and stores it in the storage unit 361 as the result DB 363.

In step S605, the program selection unit 331 selects a power control program 362 that is optimal for the notebook PC 201 based on the record DB 363. Details of the power supply control program selection process will be described later.

In step S606, the program selection unit 331 determines whether or not the program selected in step S605 (selection program) and the results of the last three selection processes (selection program) are the same. If the result of the last three selection processes is the same as the program selected in step S605, control proceeds to step S607, and if not, control proceeds to step S610.

In the embodiment, the power control program selected this time is not immediately installed in the notebook PC 201, and the results for four times including the current selection result are the same (that is, the same power control is performed four times in succession). When the program is selected), it is considered that the operating tendency of the notebook PC 201 is stable, and the selection program is transmitted to the notebook PC 201.

In step S607, the program selection unit 331 determines whether the selected program and the power control program currently installed in the notebook PC are the same. If the selected program and the power supply control program currently installed in the notebook PC are the same, the control proceeds to step S608, and if different, the control proceeds to step S609.

In step S608, the program selection unit 331 corrects the power supply control program 362 that is the same as the power supply control program 252 currently installed in the notebook PC 201, and transmits it to the notebook PC. Details of the correction process of the power supply control program will be described later.

In step S609, the program change unit 341 transmits the selection program (that is, a new program) to the notebook PC 201.

In step S610, the instruction unit 351 notifies the notebook PC 201 of release of the battery use instruction that instructs release of the use of the battery 241.

Note that the above-described processing such as selection of the optimum program and transmission of the program is performed for each notebook PC 201.

FIG. 9 is a detailed flowchart of the program selection process.
In step S611, the analysis unit 321 refers to the performance DB 363 and extracts commercial power usage information (commercial power usage time and commercial power usage) and battery usage information (battery usage time and battery usage).

In step S612, the analysis unit 321 determines whether the notebook PC 201 is used between 10:00 and 15:00. Whether or not the notebook PC 201 is used is determined from the commercial power usage information and the battery usage information. If the notebook PC 201 is used between 10:00 and 15:00, the control proceeds to step S613. If the notebook PC 201 is not used between 10:00 and 15:00, the control proceeds to step S616.

In step S613, the analysis unit 321 determines whether or not the battery usage amount from 10:00 to 15:00 is 30% or more. If the battery usage is 30% or more, the control proceeds to step S614, and if the battery usage is less than 30%, the control proceeds to step S615.

In step S614, the program selection unit 331 selects the power supply control program 362-1 (day type 1).

In step S615, the program selection unit 331 selects the power supply control program 362-2 (day type 2).

In step S616, the analysis unit 321 determines whether the operating time of the notebook PC 201 between 8 o'clock and 18 o'clock is 4 hours or less. Whether or not the operation time is 4 hours or less is determined from the total of the commercial power usage time and the battery usage time between 8:00 and 18:00. When the operating time of the notebook PC 201 between 8:00 and 18:00 is 4 hours or less, the control proceeds to step S617, and when the operating time of the notebook PC 201 between 8:00 and 18:00 is more than 4 hours, the control proceeds to step S618.

In step S617, the program selection unit 331 selects the same power supply control program 362 as the power supply control program 252 currently installed in the notebook PC 201.

In step S618, the program selection unit 331 selects the power supply control program 362-3 (night type).

FIG. 10 is a detailed flowchart of the program correction process.
FIG. 10 corresponds to step S608 in FIG.

In step S621, the program changing unit 241 determines whether or not the setting of the lower limit value of the remaining amount of the battery 241 (battery remaining lower limit value) has been canceled manually. If the setting of the battery remaining charge lower limit value is cancelled, the control proceeds to step S623, and if the setting of the battery remaining charge lower limit value is not canceled, the control proceeds to step S622.

In step S622, the program changing unit 241 determines whether or not the difference between the predicted remaining battery level at a certain time and the actual remaining battery level (that is, the estimated remaining battery level described in the performance DB 363 and the actual difference) is greater than or equal to a threshold value. To do. If the difference is greater than or equal to the threshold, control proceeds to step S623, and if the difference is less than the threshold, control proceeds to step S624. The “certain time” is, for example, the last time in a time zone in which the battery is used or scheduled to be used when going out.

In step S623, the program changing unit 241 determines whether or not the difference between the predicted remaining battery level at a certain time and the actual remaining battery level is greater than or equal to the threshold value only in the current determination. When it is determined that the difference is equal to or greater than the threshold value only in the case of the current determination, the control proceeds to step S624, and it is not only in the case of the current determination that the difference is determined to be equal to or greater than the threshold value. Then, the control proceeds to step S625.

In step S624, the program change unit 241 ends the process without correcting the power supply control program 362.

In step S625, the program changing unit 241 determines whether the battery is used or the AC power source is used in the scheduled time zone. If the AC power source is used, the control proceeds to step S628. If the AC power source is not used, the control proceeds to step S626.

In step S626, the program change unit 241 calculates the difference between the estimated remaining battery level at a certain time and the actual remaining battery level. The “certain time” is, for example, the last time in a time zone in which the battery is used or scheduled to be used when going out.

In step S627, the program changing unit 241 changes the lower limit value of the remaining amount of the battery 241 based on the difference calculated in step S626.

For example, when the battery remaining amount prediction value at a certain time (the last time in the time zone in which the battery is used) is larger than the actual battery remaining amount, the amount of battery charge required at the start of use of the battery 241 is larger than the necessary amount. It is thought that it is set small. Therefore, when the estimated battery remaining amount is larger than the actual battery remaining amount, the battery charge amount (that is, the lower limit value of the remaining battery amount) required at the start of use of the battery 241 is raised from the current setting.

In addition, when the battery remaining amount prediction value at a certain time (the last time in the time zone in which the battery is used) is smaller than the actual battery remaining amount, the amount of battery charge required at the start of using the battery 241 is less than the necessary amount. It is thought that it is set large. Therefore, when the estimated remaining battery level is smaller than the actual remaining battery level, the battery charge amount required when the battery 241 starts to be used (that is, the lower limit value of the remaining battery level) is lowered from the current setting.

In step S628, the program change unit 241 records as location information that the location where the notebook PC 201 is used can use the AC power supply.

In step S629, the program changing unit 241 has an AC power supply at the location recorded in step S628, and therefore the battery charge amount necessary for using the notebook PC 201 at the location (that is, the lower limit value of the remaining battery level). ) To lower the current setting.

In step S630, the program change unit 241 corrects the selection program based on the change in step S627 or step S629.

In step S631, the program change unit 241 transmits the corrected power control program 362 to the notebook PC 201.

Here, an example of the operation of the notebook PC before and after correction of the power supply control program will be described.

FIG. 11 is a diagram showing a notebook PC schedule and a result DB.
FIG. 12 is a diagram showing the remaining battery level and the result DB when the power control program before correction is used.

FIG. 13 is a diagram showing the remaining battery level and the result DB when the corrected power supply control program is used.

As shown in FIG. 11, it is assumed that there is a plan to use a notebook PC in the conference room A from 15:00 to 18:00.

In the conference room A, there is no AC power supply, and the notebook PC 201 uses a battery 241 as a power supply.

The control unit 211 that executes the power control program 252 installed in the notebook PC 201 acquires schedule information, and predicts the required battery amount. The schedule information describes that the notebook PC is used in the conference room A from 15:00 to 18:00 as described above.

The control unit 211 controls the use and charging of the battery 241 so that the predicted required battery amount is secured.

In the initial state, it is assumed that the battery level is controlled to be 100% at 15:00. The control unit 211 describes the battery remaining amount predicted value in the performance DB 253.

Then, it is assumed that the notebook PC 201 is used as described above, and the information collection unit 221 records the operation performance of the notebook PC 201 in the performance DB 253, and the performance DB 253 is recorded as shown in FIG.

As shown in FIG. 12, it is assumed that the difference between the estimated remaining battery level and the actual remaining battery level is 45% at the scheduled end time.

The performance DB 253 is transmitted to the management server 301 and the power control program 362 is corrected.

As described above, since the remaining battery level is higher than the estimated remaining battery level at the scheduled end time, the power supply program 362 is modified so that the secured remaining battery level is smaller than the current setting.

When the corrected power control program 252 is executed and there is a schedule similar to the above, the control unit 211 predicts that the required remaining battery level is 75% at 15:00. The control unit 211 performs control so that the remaining battery level becomes 75% at 15:00.

The notebook PC 201 is used as described above, and the information collection unit 221 records the operation result of the notebook PC 201 in the result DB 253, and the result DB 253 is recorded as shown in FIG.

As shown in FIG. 13, when the corrected power supply control program 252 is used, the difference between the estimated battery remaining amount and the actual remaining battery amount is 20% at the scheduled end time.

When the corrected power control program 252 is used, it is not necessary to secure the remaining battery level more than necessary, and more batteries 241 can be used during the peak shift / cut time period, so that the power usage can be leveled.

According to the system of the embodiment, by appropriately changing the power supply control program itself in accordance with a change in the usage status of the notebook PC (for example, a change from daytime work to nighttime work, etc.) The battery charge amount can be set appropriately.

Also, according to the system of the embodiment, conventionally, in order to leave battery power, it has been necessary to manually connect and disconnect the outlet, but automatic control is possible by the power control program. Moreover, since each notebook PC is autonomously operated by the power supply control program, peak shift / cut operation and appropriate battery management can be performed even if communication with the management server is impossible.

Further, according to the system of the embodiment, in consideration of the power consumption of the entire organization, the laptop PC is instructed to temporarily cut off the power from the commercial power source in an emergency, and the entire optimum with forcing Operation becomes possible.

In addition, according to the system of the embodiment, the power supply control program is customized according to the usage record of the notebook PC, so that it is possible to secure the battery charge amount according to the performance of each notebook PC.
