[0001]
BACKGROUND OF THE INVENTION
The present invention is applied to mobile phones and personal digital assistants having various functions. By associating priorities for personal information with battery usage, a plurality of functions are limited in battery capacity. It is related to improving the usability of the portable electronic device in a form that reflects the user's intention.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 2000-253587 discloses an example of an electronic device that enables function control of each functional unit reflecting the user's intention.
FIG. 13 is an example of an operation based on a flowchart disclosed in, for example, Japanese Patent Laid-Open No. 2000-25387, and step S41 reads a value X from a memory storing the number of functions to be secured. Step S42 determines whether or not there is a function that needs to be secured, Step S43 ends the control, Step S44 reads the total required current integration remaining amount of the functional unit that is set to secure the use, Step S44 S45 determines whether or not the remaining capacity Qc of the battery is equal to the total required remaining capacity Qrr (X-1), step S46 is a stop of functions other than the function to ensure use, and step S47 is an icon of the stopped function. Processing for erasing from the LCD display, step S48 is processing for excluding those having a low priority of the function for securing use from the function for securing usage, step S4 Is similar to step S42, determines whether there is a function to be ensured used, step S50 shows the power down state.
[0003]
Next, the operation will be described.
In the initial setting, the user sets a function to be secured for use and a time to be secured for the function to be secured when the remaining battery level is reduced. In the conventional example, the required remaining battery level Qc is calculated individually from the time for which use is desired to be secured and the power consumption of the device, and the sum of each function is obtained. In addition, when there are a plurality of functions to be secured, the priority between these functions is also set. First, in step S41, the value X stored in the memory [MEMX] storing the number of functions to be used is read. In step S42, it is determined whether X is 1 or less. When X is equal to or less than 1 (initial value), it means that there is no setting of the functional unit to be used, and the process proceeds to step 43 and the control is terminated.
[0004]
On the other hand, when X is 2 or more in step S42, it means that one or more functional units to be used have been set, and the process proceeds to step S44. In step S44, Qrr (X-1) [total required current integration remaining of the functional units of the ranks up to X-1 that are set to be secured are stored in the memory [MEMQrr (X-1)]. Amount] is read, and it is determined in step S45 whether or not the remaining capacity Qc of the battery is equal to the total required current accumulated remaining capacity Qrr (X-1). When Qc = Qrr (X-1) in step S45, the functions of all the functional units other than the functional units ranked up to X-1 are stopped in step S46. Then, the user is notified by deleting the icon of the function unit whose function is stopped in step S47. In step S48, a process of X = X-1 is executed in order to exclude a function having a low priority from functions to be secured next from functions to be secured. Further, in step 49, it is determined whether or not there is a function to be secured for use. If X = 0 in this determination, the process proceeds to step S50 and the power is turned off. If X = 0 is not satisfied in S49, the process returns to S44, and the processes of S44 to S49 are repeated.
[0005]
[Problems to be solved by the invention]
Since conventional portable electronic devices are controlled as described above, it is necessary to directly set the usage time secured by the user, and the battery capacity required to secure the power consumption of each function and the usage time of each function. However, it is difficult for users with little electrical knowledge to understand, and there is a problem that the setting considering the balance of each function cannot always be performed well.
For example, if the user is not conscious of the battery capacity, there is a possibility that the sum of the set values of each function is set to a state where the battery capacity is relatively large (for example, the battery capacity is about 50%).
In addition, by changing the settings for high-priority functions, it becomes a control method that changes the percentage of the battery that can actually be used by low-priority functions. It ’s stupid.
[0006]
In the original battery management function, it is important that the battery capacity can be used more efficiently and simply. However, as the setting becomes complicated, the user sets the high-priority function using the element of use time, for example, when the use time for securing the high-priority function is set large, the power consumption Even if it is a low-priority function with a small amount of battery, there is an inconvenience that it cannot be used even though the remaining battery level is sufficient.
While this makes it possible to set the usage time finely and control with high accuracy, it is likely to be inappropriate if the user does not have electrical knowledge, and there is a great difference in usability due to individual differences among users. There is a problem of becoming.
[0007]
Also, with this method, the usage limit is limited for each function of the device set in advance, and the user does not necessarily determine the priority for the data itself handled by the function. There was a problem that the control method could not be said to reflect the intention of the company.
In addition, there are cases where one function handles important information and non-important information, and simply determining the priority for each function does not reflect the intention of the user. It was.
[0008]
The present invention has been made to solve the above-described problems, and an object thereof is to realize battery management by setting information that does not require the user to have electrical knowledge as a setting factor. .
Specifically, it is intended to prevent a user from using other less important functions due to excessive use of less important functions without having electrical knowledge.
It is another object of the present invention to provide a power saving control method that reflects the user's intention to the maximum with respect to the functions used by the user.

[0027]
In FIG. 2, 1 is a battery, 2 is a battery remaining amount detection unit, 3 is a power supply unit, 4 is a power supply control unit, 5 is a power supply switch, 6 is a main control unit, 7 is a CPU (Central Processing Unit), and 8 is A memory (ROM (Read Only Memory)), 9 is a memory (RAM (Random Access Memory)). Reference numerals 10 to 13 denote dedicated circuit units for realizing each function of the portable terminal. As an example of the dedicated circuit unit, 10 is a function A dedicated circuit unit (wireless telephone), 11 is a function B dedicated circuit unit (music recording / playback function), and 12 is a function C dedicated circuit unit (TV (television) receiving function). , 13 is assumed to be a function D dedicated circuit section (game function). Reference numeral 14 denotes an input unit attached to the function D dedicated circuit unit 13, 15 denotes a key input unit, and 16 denotes an LCD (Liquid Crystal Display) display unit.
[0028]
The function dedicated circuits such as the function A dedicated circuit 10, the function B dedicated circuit 11, the function C dedicated circuit 12, and the function D dedicated circuit 13 are also referred to as a plurality of function units.
The battery remaining amount detection unit (remaining amount detection unit) 2 detects the remaining amount of power held by the power supply unit 3.
The power supply control unit 4 controls power supply to a plurality of function units for each function unit.
When the power control unit 4 receives the value of the remaining power level from the remaining battery level detection unit 2, the power control unit 4 controls the power to be supplied based on the received remaining power level and receives an instruction from the main control unit 6. If so, the power to be supplied is controlled based on the instruction.
[0029]
The main control unit 6 stores the program in a memory (for example, ROM 8). The program is loaded from the memory and executed by the CPU 7. The program controls execution of the operations of the plurality of functional units and sends an instruction to the power supply control unit 4. The key input unit 15 and the LDC display unit 16 are controlled. Control relating to the interface with the user, such as a function for setting importance (importance setting unit), is executed by the main control unit 6 using the key input unit 15 and the LDC display unit 16.
The memory (ROM 8 and RAM 9) provided in the main control unit 6 is used as a storage area such as an importance storage unit for storing importance levels and function-limited capacity values.
[0030]
The operation will be described below.
The user operates the key input unit 14 to select a function to be used from a function menu screen normally displayed through the LCD display unit 15, thereby selecting a function to be used and starting the selected function. .
For example, when the user selects the music playback function from the function menu displayed on the LCD display unit 15 using the key input unit 14, the function control of the portable electronic device (mobile terminal) is performed using FIGS. 1 and 2. Explain whether it works.
[0031]
For example, when the user selects a music playback function by key input, the portable electronic device starts a function control flow as S1. Each process shown in FIG. 1 is performed for each function. That is, the flow shown in FIG. 1 is executed for each function selected by the user. Therefore, when a plurality of functions are performed, the processing of the flow of FIG. 1 is performed for each function in accordance with the timing of starting use.
[0032]
In the first embodiment and the embodiments described below, the main control unit 6 (CPU 7) of the portable electronic device, when a function is selected on the menu screen, indicates a register (operation / non-operation of the function). It is assumed that the register A) is set (setting meaning operation). In addition, when the user selects to stop the function, the portable electronic device is assumed to clear (register B) indicating the function operation / non-operation (register B). To do. At the start of each function, the register (register E) indicating that the function of each function unit is restricted is cleared. The main control unit 6 executes register settings such as register A and register E.
[0033]
Next, in S2, the CPU 7 recognizes the function that has been used as a function B (music recording / playback function), and a function set by the user via the key input 14 as an initial value from the memory (RAM) 9. Read the importance of.
[0034]
Next, the process proceeds to S3. In S3, the CPU 7 refers to the function control table (FIG. 3B) defined in the memory (ROM) 8, and the remaining battery that matches the importance set value read in S2 is left. A quantity value (function limit capacity value) is determined and written to the memory (RAM) 9. The function limit capacity value at this time is a remaining battery value for stopping the corresponding function. A function-limited capacity value is calculated and determined for each function.
[0035]
Next, proceeding to S4, the CPU 7 reads from the memory (RAM) 9 in which the latest remaining amount value of the battery obtained from the output information of the remaining battery amount detection unit 2 is stored.
[0036]
In step S5, the CPU 7 compares the function-limited capacity value read in step S2 with the battery remaining amount value read in step S4. The comparison may be performed as long as the units of values to be compared are the same. For example, either the remaining amount ratio (%) or the remaining amount value itself may be used. As a result of the comparison, if the remaining battery level is not yet smaller than the function limit capacity value, it is not necessary to limit the function currently used by the user, and S4 and S5 are repeated at a constant cycle. . This cycle is a cycle that does not affect the processing capability or the like for the main function of the CPU, and an interval of about 1/10 seconds is considered to be sufficient. On the other hand, when the remaining battery level becomes smaller than the function limit capacity value, the process proceeds to S6 to perform the function limit process.
[0037]
In S6, the function B notifies the user that the use of the function B being used is restricted via the LCD display unit 16 that the battery level has reached the function restriction level. Notification to the user is not limited to LCD display. For example, notification by a vibrator existing as a general function in a mobile phone, notification by sound from a speaker, or notification by light from an LED or the like is considered as well. It is done.
[0038]
Next, the process proceeds to S7, where it is confirmed to the user whether or not the corresponding function can be stopped via the LCD display unit 16. The user determines whether or not the function can be stopped by operating the key input unit 14. In addition, although the flow about the case where the user does not input the key is not described here, the timeout time is naturally set in the key input waiting state, and when there is no key input, The process proceeds to either S8 or S9 according to a predetermined definition. If the user permits the suspension of the function, the process proceeds to S9.
[0039]
In S9, a function unit stop process is executed. The device automatically saves data for functions that need to be saved, or notifies the user of an operation for saving data via the LCD display unit 16, and stops the process of whether to save. In the case of a function that does not require processing, the function is terminated as it is. In addition, all processes necessary when each function ends in a normal use state are executed. At the end, a flag (register E) indicating that the function is restricted is set. By detecting this flag (register E), it is possible to obtain means that cannot be selected as a function of the portable device. It is also possible to acquire the value of the flag (register E) and notify the user that the function is restricted. For example, the LCD display unit 15 is notified that the function is restricted, and is controlled so that the function cannot be selected.
[0040]
S10 indicates a state where the function is stopped. Taking a mobile phone as an example, the standby screen is displayed. When the function is stopped, the dedicated circuit unit of the corresponding function is naturally saved by turning off the power control switch 5 to the corresponding function, or the dedicated circuit unit of the corresponding function. The power saving is performed by the power saving mode setting possessed by the main LSI, IC, and the like. In addition, the power consumption of the main control unit 6 is also reduced by stopping the operation of the processing related unit for the corresponding function or reducing the processing.
[0041]
Next, when the user refuses to stop the corresponding function in S7, the process proceeds to S8. The CPU 7 rewrites the function-limited capacity value read in S3 with a function-limited capacity value corresponding to the importance setting having a high rank of importance. Here, the 1 rank setting is automatically changed from the viewpoint that the user's input work such as resetting the importance in the situation that the user wants to continue using becomes annoying for the user. Although the embodiment has been described as being performed, the user may change the importance of the corresponding function directly.
[0042]
After the function limited capacity value is changed in S8, the process proceeds to S4, and S4 and S5 are similarly repeated until the remaining battery level decreases.
[0043]
FIG. 3A shows an example of an initial setting menu for the user to set the importance of each function.
Hereinafter, FIG. 3A will be described.
FIG. 3A includes four columns, and the name of the function is displayed in the first column on the left. Next, the second column from the left is a column for setting the importance, which is set by the user. Next, the third column from the left notifies the user of the function-restricted capacity value determined from the importance set by the user in the second column. Here, the user is more intuitive. The battery usage range is notified. Next, the rightmost column is a column for notifying that the function-limited capacitance value is a set value when correction based on current consumption of each function is added. Processing such as color coding is performed in a column set by the user in FIG. 3A and a column notified by the device side.
[0044]
The user sets the initial setting menu by operating the key input unit 15 to display the initial setting menu on the LCD display unit 16. The setting is determined by, for example, sequentially selecting A, B, and C with the arrow keys of the key input unit in the importance column and pressing the determination key of the key input unit at the corresponding importance level. By referring to the table shown in FIG. 3 (B) based on the set importance, the function limited capacity value is obtained. The obtained function limit capacity value is displayed as a battery use range in the third column as a value of [100% to function limit capacity value], and is notified to the user so that it can be understood intuitively. From the viewpoint of being able to understand intuitively, the display of this part is not a numerical value, and the same can be realized even if notified by a bar display.
[0045]
Furthermore, when all the importance levels are set, the power analysis correction shown in FIG. 4 is performed, and when it is determined that correction is required for the setting of the function restricted capacity value, the correction is performed. This correction is a function with a low importance level, or a function with sufficiently low power consumption. Do something that prevents the problem of obstruction. In other words, even if the function has a low importance level setting, the function with low power consumption is an electronic device in which the function limited capacity value is corrected to a value lower than the normal setting to improve the convenience of each function of the user.
[0046]
Hereinafter, the power analysis correction process of FIG. 4 will be described.
Since the power analysis correction is performed for a function having a low importance level, a means for realizing the importance level C having the lowest importance level as an example will be described in the present embodiment.
[0047]
In step S3-1, the function name and the current consumption value set in the importance C are detected from the initial setting values set by the user using the initial setting menu, and X (n), Y (n ) In a memory (RAM). In the case of the example of the initial setting as shown in FIG.
X (1): Current consumption Y (1): Function C
X (2): Current consumption value Y (2): Function D
The current consumption value when each function is operated is stored in a memory (ROM) as an initial value of the device.
[0048]
Next, proceeding to step S3-2, the number of detected functions set to importance C is stored in K. K is the number of cases to be corrected, which indicates that it is necessary to implement the correction as many times as set in K, and is a control condition for the number of correction determination loops.
[0049]
Next, the process proceeds to step S3-3, and the current consumption of the function set to the importance level B is detected in order to make the correction determination target for the function of the importance level C, and the smallest current consumption value is set to the coefficient B. Store as.
[0050]
Next, it progresses to step S3-4 and the reference | standard for determining whether power correction is executable is calculated | required. Since the correction is performed when the current consumption of the function of importance C is sufficiently smaller than the importance B, in this example, 10% of the current consumption of importance B is determined as a reference. A reference value is obtained by multiplying the coefficient B obtained in S3-3 by 0.1, and this value is stored in Z. Z is a reference value for determining whether to perform power correction.
[0051]
Step S3-5 is a variable setting process for designating the storage location in order to sequentially compare the function detected as importance C with Z obtained in S3-4.
[0052]
Step S3-6 is a process for comparing the current consumption of the function detected as the importance C with the reference value Z determined in S3-4 to determine whether or not to execute power analysis correction. For all the functions designated by the importance level C, it is determined whether or not the power analysis correction is executed at this step when the variable n changes. For the function that is determined to execute the power analysis correction with the function that consumes very little power, the process proceeds to S3-7, and the correction is executed. Further, since the power is large, nothing is changed when the power analysis correction is not executed. This process repeatedly executes the same process for the next function. Step S3-11 is a determination as to whether or not there is still a function to be determined. The power analysis correction is performed assuming that all determination operations are completed when the determined number n is equal to the number K that needs to be determined. The process ends.
In S3-11, if there is still a function to be determined, n + 1 is stored in n, the next corresponding function is designated, and the power analysis correction in S3-6 is determined. Loop.
[0053]
Next, when it is determined in step S3-6 that power analysis correction is to be performed, the process proceeds to step S3-7. In S3-7, the function name stored in Y (n) is read. Next, proceeding to S3-8, the function-limited capacity value determined by the user in the initial setting for the corresponding function is changed to a value corresponding to a level (B in the case of the present embodiment) that is one rank higher in importance. . By this processing, the function limited capacity value obtained by adding power analysis to the importance is set to the corresponding function. Next, the process proceeds to S3-9, and the corresponding function column of the battery usage range notification in the importance initial setting menu shown in FIG. 3A is set to [100% to function according to the newly set function limit capacity value. The limit capacity value (updated value)] is displayed.
[0054]
Furthermore, in S3-10, in order to notify the user that the battery usage range determined here is not only the importance level but also the power analysis correction is applied, for example, a ☆ mark is applied to the power analysis correction. Displayed in the function column (FIG. 5). Until the process of S3-10, the process of power analysis correction is completed for the corresponding function, the process proceeds to step S3-11, and if there is a function that needs to be determined whether the power analysis correction is appropriate, the process loops to S3-6. If not, the process ends.
This power analysis correction process is necessarily performed when the user changes the importance initial setting menu shown in FIG.
[0055]
As described above, in the present invention, by controlling each function based on the flow described above, the area in which the battery can be used is limited according to the importance of the function as shown in FIG. Therefore, it is possible to prevent overuse of low-functions and protect the use of important functions in a balanced state as a whole. As a feature of the present invention, only the general judgment ability, which is considered to be important when the user thinks by comparing functions vs. functions without being aware of the capacity or power consumption of the battery, etc. In this way, it can be linked to the device condition setting. Since the user does not use any electrical knowledge, optimal battery management can be realized regardless of the presence or absence of the user's electrical knowledge.
[0056]
Furthermore, as the devices become multifunctional, the information handled by the devices becomes various. Whether or not it is an important function depends not only on the function of the device but also on the information handled by using the function. In the above embodiment, the battery is operated by the steps to S7 and S8. Since the user's intention is reflected again when the remaining capacity falls below the function-restricted capacity value, not only the functions used by the user, but also the information handled on the user's side, the user's intention Battery management that makes it possible to follow In addition, regarding the setting of the function limit capacity value, by having power analysis correction based on the ratio of power consumption between the functions with high importance and the functions with low importance, unnecessary function restrictions are prevented, and as much as possible over a wide range of batteries. While taking into consideration that many functions can be used, it is possible to protect the use of important functions and to realize a portable electronic device that is very easy to use for the user.
[0057]
This method is simpler and more user-friendly than the method of setting power consumption for each function shown in the prior art and setting the time to use, so that anyone can make appropriate settings. Can do. According to the present invention, it is possible to improve the disadvantage of the prior art that a user who has little knowledge of power consumption, remaining battery power, etc., is likely to have an inappropriate setting.
[0058]
This flowchart does not describe the user's arbitrary function stop, but this flowchart describes the part related to function restriction. If the user arbitrarily stops the function, It is assumed that all values set in the flowchart are changed to initial values and the function is stopped.
[0059]
As described above, this embodiment is a portable electronic device that uses a battery having a function unit capable of operating a plurality of functions independently, and the function unit is independent of the user. It is set by importance setting means for determining the respective importance levels, means for detecting the remaining battery level of the main power source, function stopping means for independently stopping the operation of the function unit, and the importance setting means. Each function part operation stop control means for controlling the function stop means from the relationship between the importance level and the remaining battery level for operating each function part, and means for detecting the operation / non-operation of each function part, Notification / change function] means for detecting that the notification time has been reached, means for detecting information breaks (for example, between music playback songs, TV reception CM, etc.), and the importance of each functional unit shown in the present invention By function stop means executed according to the setting And means for detecting that it has been stopped, also has been described a portable electronic device having an importance setting menu the user can initially set.
[0060]
In addition, each of the functional unit operation stop control means is set to stop the function independently when the remaining battery level is increased in descending order of importance set by the importance setting means. Each function part operation stop control means for controlling the means is characterized in that
[0061]
In addition, the setting menu screen has a column for notifying the user of the battery usage range in which the corresponding function can be used when setting by the importance setting menu.
[0062]
Each functional unit operation stop control means has a storage circuit (power storage unit) that stores in advance the operating power or operating current when each functional unit operates, according to the operating power, A power analysis correction function that automatically corrects the function-limited capacity value determined by the importance level by comparing the power consumption with the other functions with respect to the importance level set by the importance level setting means. It is characterized by that.
[0063]
Further, the setting menu screen has means for notifying that the power analysis correction has been applied in calculating the battery usage range to be notified to the user at the time of setting by the importance setting menu.
[0064]
Embodiment 2. FIG.
Embodiment 2 of the present invention will be described below with reference to the drawings.
First, FIG. 6 and FIG. 7 are flowcharts for connecting terminals A and B. 6 and 7, step S1 indicates that the user has selected an arbitrary function and the use has started, and step S2 indicates reading of the importance setting value set by the user on the initial setting screen. Step S3 shows the start processing of the timer for counting the usage time of the function, Step S4 shows the determination of the function limit capacity value, Step S5 shows the reading of the current remaining battery level, and Step S6 shows the user Step S7 shows the function restriction suitability determination, step S8 shows the corresponding function stop notification processing, step S9 shows the user stop permission determination processing, and step S10 shows the function The change of the limit capacity value is shown, step S11 shows a process of notifying the user of the current importance setting value for the function in use, and step S12 shows the resetting of the importance The user's intention confirmation process with respect to the suitability of the user, step S13 indicates the importance level setting change process, step S14 indicates the function limit capacity value determination process, and step S15 indicates the time setting value setting process until the next notification Step S16 indicates a function end process, and Step S17 indicates a function stop.
[0065]
FIG. 8 is a configuration diagram showing the second embodiment.
In this example, a timer 17 is further added to the first embodiment. Hereinafter, the operation of the second embodiment will be described with reference to FIGS.
[0066]
As in the first embodiment, a case where the user selects and uses a music playback function will be described as an example. S1 indicates a function control flow start. Next, proceeding to S2, the importance level of the corresponding function is read as in the first embodiment.
[0067]
Next, in S3, the timer 17 is started. The timer 17 notifies the CPU when a predetermined time has elapsed. Here, the timer 17 is shown as a hardware configuration, but the timer need not be a clock function that can understand the real time, and can be realized by simple means such as a loop count or the number of times a function is used. is there.
Next, the process proceeds to S4, and the function-limited capacity value is determined from the read importance, as in S3 of the first embodiment.
Next, the process proceeds to S5, and the actual remaining battery level is read as in S4 of the first embodiment.
Next, the process proceeds to S6, and it is determined whether or not the timer 17 started in S3 has elapsed. For example, if the signal input indicating the timer status is at a low level, the timer 17 determines that the specified time has not yet reached, or if the signal input is at a high level, the timer time has passed a specified value. Do. Also, in the case of counting by software, it can be realized by determining the flag value of the corresponding register by providing a register indicating a timer status flag.
[0068]
Next, when progressing to S7, S5-S7 is repeated.
Further, when the timer 17 has passed the notification time, the process proceeds to S11 in order to reflect the user's intention in the battery management. A feature of the second embodiment is a portion shown in steps S11 to S15. The notification time is determined as the program value of this flow, but this notification time is a time for detecting a case where the user uses the function continuously to some extent, for example, about 10 minutes. The setting is assumed. This is based on the point that it is not necessary to treat it as a target of battery management that restricts functions with a little use. This is because it is assumed that the continuous usable time of the device (time until the battery becomes empty from the fully charged state) is about several hours or more, and the continuous usable time of the device is extremely short. In some cases, of course, this notification time needs to be shortened.
[0069]
In S <b> 11, the portable electronic device according to the present invention notifies the user of the setting of the importance level of the function in use that the user has set as an initial setting value via the LCD display unit 16. Next, the process proceeds to S12, and a setting screen is displayed so that the user can change the importance setting as necessary. When the user operates the key input unit 15 and selects not to change the setting, the process proceeds to S15. If the user selects to change the importance level setting, the process proceeds to S13, where the importance level setting change screen is displayed on the LCD display unit 16, and the user arbitrarily selects the importance level and restarts. Is set. However, the setting change here does not change the value of the initial value on the memory (RAM), but changes the value read in S2. Depending on the specifications of the device, the initial value can be changed by rewriting the initial value stored in the memory (RAM).
[0070]
Next, in S14, based on the importance changed in S13 as in step S4, a function limit capacity value (a battery remaining value for stopping the use of the function and limiting the function) is determined in advance. It is determined by referring to the function control table (FIG. 5).
[0071]
Next, in S15, the notification time is set to, for example, 24 hours (a time during which the function is not continuously used), and once resetting is prompted, the notification to the user may be repeated again. It is processed so that there is no. The notification time is set to 24 hours as an example above. However, the notification time is set so that notification to the user is not re-executed as much as possible during continuous use of the same function. There is no problem.
[0072]
In a state where the setting of the timer 17 is substantially invalidated, the process returns to S5, and S5 to S7 are repeated until the remaining battery level falls below the function limit capacity value.
[0073]
This flowchart does not describe the user's arbitrary function stop, but this flowchart is for describing the part related to the function restriction, and when the user arbitrarily stops the function. It is assumed that all values set in this flowchart are changed to initial values and the function is stopped.
Also, even if the termination stop condition of the function in use is met, the termination process is executed after obtaining the user's permission, and the user is given an opportunity to change the setting so that it can be used continuously at that time. As a result, it is possible to reflect the priority of the data itself being handled, and it is possible to perform power control that reflects the user's intention as compared with the prior art.
[0074]
According to the present invention, when the user starts to use the corresponding function and continuously uses it, the importance level is automatically notified so that the current setting can be recognized again and the user can actually For example, when handling more important information than the assumed importance of the function when the initial value is set, the importance is set according to the information currently handled by the user at that time. Can be reset higher. Conversely, it is naturally possible to reduce the importance.
As described above, the portable electronic device according to the present invention can restrict functions not only according to the function but also according to information handled by the user on the function, more reflecting the intention of the user. Battery management can be realized.
[0075]
As described above, in this embodiment, the importance setting means can be set as an initial setting in a situation where the user is not using the function, and the user can start using any function. It has a functional operation start detection unit that detects that, at the same time as the functional operation start detection by the functional operation start detection unit, a time measurement unit that starts time calculation, and after a certain period of time measured by the time measurement unit, A portable electronic device having a notification function for notifying the user of the importance level currently set and a importance level changing function for newly changing the importance level has been described.
[0076]
In the time measurement by the time measurement unit, in a state where the remaining battery level is sufficient, this time measurement is not executed, or the time measurement is cleared so that an arbitrary time does not elapse, or It has a function of stopping the notification function for notifying the importance level and the importance level changing function so as not to operate.
[0077]
Embodiment 3 FIG.
As for step S6 in FIG. 6, in the second embodiment of the invention, the notification time is set and realized in advance as a determination value of the program, but in the third embodiment, in order to obtain a more appropriate notification time, Realized as follows.
The third embodiment of the present invention will be described below with reference to FIG.
In this description, the step 6 (S6) portion of FIG. 6 of the second embodiment will be described, and step numbers will be described as S6-1, S6-2,.
[0078]
S6-1 in FIG. 9 corresponds to S5 in FIG. S6-2 indicates a process for determining whether the remaining battery level is 50% or more, S6-3 indicates a process for setting a maximum time as a notification time, and S6-4 indicates a notification time setting flag. S6-5 represents a process for obtaining the operable time of the function in use by calculation, S6-6 represents a process for obtaining the notification time from the operable time, and S6-7 represents the notification time. S6-8 indicates processing for resetting the usage time count of the function in use to zero, S6-9 indicates reading usage time, and S6-10 indicates The comparison process of the usage time and the notification time is shown. If the usage time has passed the notification time, the process proceeds to S6-11, and otherwise the process proceeds to S6-12. S6-11 corresponds to S11 in FIG. 7, and S6-12 corresponds to S7 in FIG. The processes up to S6-1 in FIG. 9 and the processes after S6-11, S6-12 in FIG. 9 are the same as those in FIGS.
[0079]
Next, notification time calculation processing for notifying the user of importance according to the third embodiment and operations up to the notification will be described.
Similar to the second embodiment, the importance determined by the user at the initial setting when proceeding to S5, the function-limited capacity value determined from the importance, and the reading of the current battery level are completed. Yes. Here, in S6-2, a comparison process is performed to determine whether or not the remaining battery level is below 50%. If the remaining battery level is 50% or more, the user still needs to be aware of the remaining battery level and use the device. If it is determined that there is no notification, the process proceeds to S6-3, and the notification time is provisionally set to a time that does not actually occur. The time setting shall be the maximum value.
For example, it would be sufficient if a setting of about 24 hours is possible. Here, 50% is used as a criterion for determining whether or not to set the notification time. However, this value itself is a value set according to the feature of the device, and it does not have to be 50% in particular. .
[0080]
Next, proceeding to S6-9, the CPU 7 reads the time during which the in-use function has continuously operated from the timer 17 that is counting the time. Next, proceeding to S6-10, it is determined whether or not the continuous operation time of the function in use has passed the notification time setting. If the process branches off from S6-3, the determination here is basically NO, and the process proceeds to S6-12. S6-12 corresponds to step S7 in FIG. 6 of the second embodiment. When the remaining battery level is sufficient, steps S5 to S7 in FIG. 6 of the second embodiment are repeated, and the entire flowchart (FIG. 9) of the present embodiment is in the loop of steps S5 to S7 in FIG. Will be repeated.
[0081]
Next, when the remaining battery level is less than 50% in the determination branch of S6-2, the process proceeds to S6-4. As the process of S6-4, a time for notifying the user of the importance is set. Whether or not a flag indicating whether or not is set is determined. If the flag is set, the time for notifying the importance has already been set, and the process proceeds to S6-9. The steps after S6-9 are the same as above. If the flag is not set, the process proceeds to S6-5. The flag is set in advance by the user via the key input unit 15.
[0082]
Proceeding to S6-5, in order to determine the notification time, an approximate value of the time when the in-use function is continuously used is obtained. For the calculation, a usable battery remaining value is obtained by subtracting the function limit capacity value from the current battery remaining capacity and multiplying by a coefficient such as discharge efficiency. The obtained battery remaining value is obtained by dividing by the consumption current value defined in the table for obtaining the function-limited capacity value.
[0083]
Next, it progresses to S6-6 and the notification time which notifies a user of importance is determined by the ratio with the continuous availability time calculated | required by S6-5. In the present embodiment, 20% is set as the notification time, and the value obtained by multiplying the operable time of the function in use obtained in S6-5 by 0.2 is notified of the importance to the user. Set as time. Further, a flag indicating that the notification time is set in S6-7 is set.
[0084]
Next, in order to measure the time set in S6-6, the operation time counter that has been measured so far is reset, the measurement is restarted from zero, and the process proceeds to S6-9. The steps after S6-9 are as described above.
[0085]
In the third embodiment, the means for notifying the user of the degree of importance is different from the second embodiment that is determined by uniformly setting at the initial stage, and the state and function of the battery that the user has started using. It is an example of calculating the notification time that seems to be optimal from the current consumption of the battery, and notifying the user of the importance level, and in the state where there is enough battery, without giving annoying notification to the user, In addition, in a state where the remaining battery level is low or the battery capacity is consumed, the user can be notified quickly and can be realized so that more effective function restriction can be performed.
[0086]
As described above, in this embodiment, the notification means includes a means for calculating and notifying the notification time setting according to the remaining state of the battery, the consumption current of the function used, and the like. The portable electronic device is described.
[0087]
Embodiment 4 FIG.
The fourth embodiment has a configuration similar to that of the second embodiment. The difference between the second embodiment and the second embodiment is that when the specified time is reached by counting the continuous use time of the function, The setting value of the importance level is notified, and the user is given an opportunity to change the setting value according to the importance of the information handled on the function currently used by the user. On the other hand, the present embodiment is characterized in that the division of information handled in terms of functions is detected, and when the specified number of times is reached, the importance level notification and the change opportunity are similarly obtained. For example, in the case of a music recording / playback function (music playback function), notification is made by detecting that a predetermined number of songs have been played, and in the case of TV, notification is made by detecting the number of transitions to CM. In a game, this means that the number of game over is detected and notified. The fourth embodiment will be described as an embodiment in the case of music reproduction.
[0088]
The fourth embodiment of the present invention will be described below with reference to FIGS.
FIG. 10 and FIG. 11 are flowcharts for connecting the terminal A and the terminal B.
Further, the same steps as those in the second embodiment are denoted by the same step numbers as those in FIGS. 6 and 7, and the description thereof is omitted. In the processing unique to the fourth embodiment, the step numbers are the portions of S8-1 to S8-7. This will be described below.
[0089]
Step S8-1 shows a process of setting the number of songs to be listened to continuously, and shows that three songs are set as an embodiment. Next, step S8-2 indicates that zero is set to the initial value of the register for counting the number of music pieces that have been reproduced. Next, in step S8-3, initialization of the song end status flag set in the control register of the music recording / playback unit (FIG. 2, function B dedicated circuit unit 11) and the status flag are read and stored. The initialization process of the register C used in FIG. Here, it is assumed that the end status flag is set in a main function control routine different from this processing routine, and this flag is set at the end of the song as a trigger. When the flag is withdrawn from the outside, it is assumed that the flag is not set until the end of the next song.
[0090]
Next, through S4 to S5, the process proceeds to step S8-4, where the music end status flag is read and set in the register C (FIG. 2). Here, the status flag is reset simultaneously with reading. Next, the set value is determined in S8-5. When the register C = 1, it indicates that the music has ended, and when the register C = 0, it indicates that the music is being reproduced. Here, when the register C = 0, the process proceeds to S7, and no special process is performed until the music ends or the battery capacity falls below the function limit capacity value, and the process loops between S5 and S7.
[0091]
Next, in S8-5, if register C = 1 and it is detected that the music has ended, the process proceeds to S8-6, and the count of the number of music is incremented by one. For register C, the value is initialized to zero in order to detect the end of the next song. Further, since the status flag has already been reset when S8-4 is executed, the processing here is not necessary. Next, the process proceeds to S8-7, where the number of songs S counting the end of song playback is compared with the value K that defines the number of songs to be listened to continuously, and if they are the same, branch to terminal A in FIG. Then, the process proceeds to a process for notifying the user. The importance level notification / importance level resetting process is the same as that of the second embodiment, and is performed by S11 to S14. Next, it progresses to S8-8. Here, in order to set the notification to the user not to be executed again, as in the second embodiment, in order to realize a value that is practically impossible, as a notification condition, as an example, the number of songs that are continuously listened to Set K to 100 songs and return to S7. The steps after S7 are processed in the same manner as in the first and second embodiments when the remaining battery level falls below the function limit capacity value set based on the set importance.
[0092]
As described above, in the fourth embodiment, in the notification that the user is using the function, for example, it is possible to eliminate the notification of the importance level while listening to music, and the song is finished. It becomes possible to notify in the meantime, and it is possible to notify the user without discomfort.
[0093]
As described above, in this embodiment, the notification means is not time-measured by the timer unit, but by measuring the number of times when the information handled by each function is switched, without impeding the use of the user. A mobile phone having notification means for notification (for example, if the music playback function is used, the number of music playback songs is measured and notified between songs; if the TV function is used, the number of CMs is measured and notified during the CM) A type electronic apparatus has been described.
[0094]
Embodiment 5. FIG.
The embodiment of the present invention differs from the above 1-4 in the method of setting importance. In the first to fourth embodiments, the control is based on information that the user sets the importance of the function of the device in the device. However, the fifth embodiment realizes that importance level is set by holding data that determines the importance level on the information file side that is actually handled on the function, and detecting and reading the data to the device side. It is a method. For example, when viewing a document, the data structure has a document property that retains the importance level setting in the document file data. It is conceivable that the importance level is detected and reflected in the importance level setting on the device side.
[0095]
In the present embodiment, an example in which the importance level is set on the device side by holding data serving as a reference in determining the importance level of each television broadcast in the electronic program guide and downloading it to the mobile device. Show. The data used as the standard for determining the importance can be realized by defining the value set as the importance directly as data, or the type of TV broadcast (news, weather forecast, drama, variety, movie) It is also possible to determine the importance by education). In this case, a setting menu in which the user sets the importance level for each category of the TV program can be realized in the same manner as in FIG.
[0096]
Embodiment 5 of the present invention will be described below with reference to the drawings.
In FIG. 12, the same step numbers as those in FIG. 1 are assigned to steps for performing the same processing as in the first embodiment, and the following description is omitted. Further, the processing peculiar to the fifth embodiment is denoted by step numbers S9-1 and S2, and will be described below.
[0097]
In step S9-1, the user starts using the TV reception function. The TV shown here shows reception of terrestrial digital television in which the main broadcast is started after 2003 as an example of use.
In step S9-2, the user downloads an electronic program guide in order to select reception of TV. Next, in step S9-3, the user selects a program to be viewed by channel selection. At this point, browsing of the TV broadcast is started. Next, proceeding to step S9-4, the portable electronic device according to the present invention detects the type of broadcast of the selected channel from the data of the electronic program guide (for example, content such as news, weather forecast, drama, variety). data).
In step S9-5, the importance level corresponding to the broadcast type is determined from the importance level setting data set by the user as the initial setting of the TV function based on the read broadcast type. The importance level setting can be configured in the same manner so that the function column in FIG. 3A corresponds to the TV broadcast type column, and thus description thereof is omitted.
[0098]
After the importance is determined according to the type of TV broadcast in step S9-5, the process is basically the same as in the first embodiment, and the function limit capacity value of the battery is determined from Table 2 in S4. Next, it progresses to S9-6. It is confirmed whether or not the TV channel has been changed. If the TV channel has been changed, the process returns to S9-4 again to set the importance level. If the channel is not changed, the process proceeds to S5, where the function-limited capacity value and the remaining battery level are compared. If the remaining battery level is large, no special processing is performed until the remaining battery level is reduced. repeat. Further, when the remaining battery level is reduced, the process proceeds to the execution of the stop process after S6. Since S6 and subsequent steps are the same as those in the first embodiment, description thereof is omitted.
[0099]
As described above, in the fifth embodiment, it is possible to set the importance level of a function based on data set in information used by a user. Whether the function of the mobile device is important or not is naturally determined by the information handled on the function, and the function restrictions for battery management are not determined by the function, but on the function. More ideally, it is determined by the information used. Therefore, according to the present invention, it is possible to set a function restriction in ideal battery management, and it is possible to realize a portable electronic device that reflects the user's intention more.
[0100]
As described above, in this embodiment, the importance level is held in the information handled by each function, and by reading the importance level held on the information side, a portable type having means for setting the importance level in the device The electronic device has been described.
According to the present invention, the setting for controlling the power consumption can be performed based on each function.
[0101]
Embodiment 6 FIG.
The power control of the portable electronic device described in the above embodiment can also be realized by a program (power control program). The program is stored in a memory (ROM 8 and RAM 9 in FIG. 2). The program stored in the memory is loaded and executed by the CPU 7.
The program can be recorded on a computer-readable recording medium. The program recorded on the recording medium is similarly loaded and executed by the CPU 7.
[0102]
Embodiment 7 FIG.
It is also possible to add a function for changing the value of the function restricted capacity value stored in the function restricted capacity value table shown in FIG. 3B to the portable electronic device described in Embodiment 1. An example will be described below.
A function limit capacity value screen is displayed that includes a column for inputting the function limit capacity value corresponding to the importance level.
The user inputs the function restriction capacity value to the column for inputting the function restriction capacity value.
The key input unit 15 receives the function-limited capacity value input from the user and passes it to the main control unit 6.
The main control unit 6 stores the input function limit capacity value in the function limit capacity value table. In this way, the function limited capacity value table can be updated.
Thereafter, the main control unit 6 calculates the usage range using the updated function restricted capacity value table.
[0103]
The above function is effective when a user who has become accustomed to using a portable electronic device wants to adjust the function-limited capacity value in accordance with his / her own usage situation.
Further, since the function-limited capacity value can be easily changed, the power source of the portable electronic device can be effectively used.
[0104]
【The invention's effect】
According to the present invention, the setting for controlling the power consumption can be performed based on each function. Further, power consumption can be controlled based on the importance set by the user. Specifically, in the portable electronic device, the importance of the function is set as a user's setting item, and the electrical knowledge part for controlling the function restriction corresponding to the actual battery capacity is given to the device side. The setting of importance (function importance) is based on the judgment of each individual, and is an element that does not require any electrical knowledge for the user under general daily life. Setting the importance level by the user improves the setting variation and inconvenience of the user, and anyone can use the battery efficiently and conveniently.
[0105]
In addition, the functions can be stopped in order of decreasing importance.
[0106]
In addition, by providing a screen for inputting the importance and the function restricted capacity value, the user can easily specify and change the importance and the function restricted capacity value. Therefore, based on the importance set for each function by the user, the remaining battery level that can be used by each function can be limited.
[0107]
In addition, by holding the electric energy value necessary for each functional unit to operate, an appropriate function-limited capacity value can be calculated using the electric energy value.
[0108]
Further, by displaying the power usage range that can be used by each functional unit on the importance setting screen for setting the importance, a more appropriate importance can be set.
[0109]
Further, by prompting the user to change the importance level after a predetermined time has elapsed, a function reflecting the intention of the close user can be executed. Moreover, it becomes easy to reflect a user's intention.
[0110]
Further, by urging the user to change the importance level based on the remaining power level, it is possible to change the importance level according to the remaining power level.
[0111]
In addition, by using the remaining amount of power and the amount of power consumed by each functional unit, it is important to change the importance of the user, so that it is important depending on the remaining amount of power and the expected amount of power consumed. The degree can be changed.
[0112]
In addition, it is possible to detect a break in the operation of the function and prompt the change of the importance according to the break in the operation of the function.
[0113]
Also, importance level information can be obtained directly from a plurality of functional units by holding importance level information in each of the plurality of functional units.
[0114]
In addition, by displaying the stopped function on the function selection menu, it is possible to notify the user of the operation status of the function.
[0115]
Further, when the operation of the function is stopped, it is possible to avoid the function from being stopped in the middle of the operation by using the division of the operation of the function.
