Description

  The present invention relates to a portable information processing terminal, and more particularly to a portable information processing terminal equipped with a battery and having a function of managing the battery.

  In recent mobile terminals, various convenient functions such as a camera, a video function, a music playback function, or a Bluetooth function are additionally installed in addition to the original telephone function, and the battery consumption of the terminal tends to increase year by year. Therefore, to prevent inconvenience to the user due to unexpected battery exhaustion, the battery current and battery voltage are measured and the remaining battery time and remaining battery time are displayed, or the power consumption is reduced when the battery voltage falls below the specified battery voltage. It is equipped with functions such as limiting the functions that can be used to suppress it.

  For example, the following Patent Document 1 discloses a technique for calculating the remaining time by updating the remaining battery capacity and the average power consumption per unit time for a predetermined number of times to the power consumption of the corresponding operation mode. Is disclosed. However, when an operation mode that has not been operated on a recent portable terminal that can be operated from a combination of many functions is selected, the remaining time cannot be calculated unless the time corresponding to the number of times of measurement has elapsed. Further, there is a problem that the remaining time cannot be calculated except for the actual operation. Patent Document 2 below discloses a technique for calculating the remaining battery time using only the battery consumption amount registered in advance for each operation function. However, there is a problem that there is no correction due to a change in voltage that varies the battery consumption, and an appropriate calculation result is not obtained.

In the embodiment, a mobile phone will be described as an example of a portable information processing terminal. However, any information processing terminal such as a PDA, a notebook computer, an electronic dictionary, or a portable audio player may be used.

  A first embodiment of the present invention will be described with reference to FIGS. 1 to 3 are diagrams showing the configuration of a mobile phone, and FIGS. 4 to 5 are diagrams showing stored data. 6 to 7 are diagrams showing display examples of the screen of the mobile phone, and FIGS. 8 to 10 are diagrams showing operations of the mobile phone.

[Constitution]
As shown in the external view of FIG. 1, the mobile phone 1 in this embodiment includes a main LCD screen 11 that is a display unit, a keyboard 12 that is an operation unit, a microphone 13, and a speaker 14. As shown in the block diagram of FIG. 2, the mobile phone 1 includes therein a control unit 2 that is a CPU that controls the operation of the mobile phone 1 itself, and a flash memory that stores predetermined information. Part 3. Hereinafter, in particular, the control unit 2 and the storage unit 3 will be described.

  As shown in FIG. 2, a predetermined program is incorporated in the control unit 2, so that the voice processing unit 21 that processes the voice input from the microphone 13 or the voice output from the speaker 14 and the keyboard 12 input. A key code recognizing unit 22 that discriminates the key that has been selected and a screen control unit 23 that controls the display state of the main LCD screen are constructed. The screen control unit 23 includes a battery management processing unit 24 that manages the state of the battery. Further, a battery data storage unit 31 is formed in the storage unit 3.

  As shown in FIG. 3, the battery management processing unit 24 further includes a management setting processing unit 241, a battery voltage reading processing unit 242, and an operation pattern detection processing unit 243 according to a program incorporated in the control unit 21. And a battery remaining value calculation processing unit 244 are constructed. Each of these processing units 241 to 244 has a function of displaying processing contents on the main LCD screen 11 as necessary. The battery data storage unit 31 includes a setting storage unit 311, a battery output change storage unit 312, and a battery consumption storage unit 313. Hereinafter, the processing units 241 to 244 and the storage units 311 to 313 will be described in further detail.

  First, the management setting processing unit 241 has a function of performing various settings relating to battery management based on information input by the user from the keyboard 12 and storing the setting information in the setting storage unit 311. For example, as shown in the battery setting screen of FIG. 7B, a setting for enabling / disabling the battery management function and a setting for enabling / disabling a correction mode for correcting a difference from default data due to battery deterioration. Has the function to perform. In addition, as shown in the battery setting screen of FIG. 7B, the management setting processing unit 241 sets the target date and time (target time) that the battery of the mobile phone 1 desired by the user lasts when the battery management function is enabled. ) And stores the target date and time information in the setting storage unit 311 (target time storage means). Furthermore, as shown in the battery information warning screen of FIG. 6 and the battery information screen of FIG. 7C, the management setting processing unit 241 inputs the pattern number of the operation pattern scheduled to be operated by the mobile phone 1 from the user. It has a function of accepting and setting to calculate the remaining value of the battery in the operation pattern (operation pattern setting means).

  Here, as shown in FIG. 4, the battery consumption storage unit 313 (battery consumption storage means) is a battery at the time of operating each operation pattern for all functions that the mobile phone 1 can operate, that is, operation patterns. Consumption information representing consumption is stored. This consumption information is, for example, a value measured in advance by experiment or a value calculated by theoretical calculation, and a value that is corrected and recorded based on the calculation result of the remaining battery value so far, as will be described later. is there. For example, in FIG. 4, there are eight types of main functions (eg, standby, camera, music playback function, etc.) that are operation patterns that can be operated by a mobile phone, and sub-functions (back This shows a case where there are a plurality of types of functions that can be set in common to each main function, such as the light setting. Specifically, the operation pattern that is the main function is classified into P1 to P8 patterns according to the battery consumption, and divided from the battery voltage BT10 at the time of battery charging to BT0 when the battery is exhausted and divided in units of 0.1V (per fixed voltage) The battery consumption in each operation pattern of each voltage is registered. The divided voltage may be as fine as possible depending on the memory and reading accuracy, and conversely, the division width may be widened. Similarly, the sub-functions are classified and registered in units of battery consumption from P100 to P105. The maximum consumption in FIG. 4 represents the maximum capacity of the battery. Note that the remaining capacity information of each operation pattern can be corrected and recorded based on the calculation result of the remaining battery value, as will be described later.

  The remaining battery time column of the battery consumption storage unit 313 stores remaining time information indicating the remaining driving time of the mobile phone 1 at each output voltage value for each operation pattern described above. For example, when the battery output voltage is BT7 (4.1 V) in the operation pattern P1, it is stored that the remaining 160 hours of driving is possible. However, the remaining battery time is information that can be calculated if the current remaining battery capacity, the operation pattern, and the consumption in the operation pattern are known. This remaining time information can also be corrected and recorded based on the calculation results of the remaining battery value so far, as will be described later.

  Next, the battery voltage reading processing unit 242 (voltage detection means) detects the current output voltage value of the battery. In addition, the operation pattern detection processing unit 243 (operation pattern detection means) detects an operation pattern that is operating in the mobile phone 1, that is, which function is operating among the main functions and sub-functions described above. Then, the battery voltage reading processing unit 242 and the operation pattern detection processing unit 243 indicate the detected operation pattern (a combination of the operation patterns in the case of a plurality of times) and the date / time data operated at a certain voltage interval as battery output change information. Is stored in the battery output change storage unit 312 (battery output change storage means). Here, an example of the battery output change information stored in the battery output change storage unit 312 is shown in FIG. As shown in this figure, a change state of the battery such as an operation pattern, its consumption, and date / time information when changing to each output voltage value is stored in one cycle from completion of charging to battery disconnection. Specifically, from 12:30 on August 1, when charging is completed, it operates for 2 hours with the operation pattern P5 + P100 + P102, then for P6 + P103 for 1 hour, P2 + P102 + P102 for 1 hour, and P7 + P100 + P107 for 3.7 hours. As a result, the battery is exhausted. And the time described corresponding to each battery voltage memorize | stores the time when it became the battery voltage. In addition, the consumption column is a total of the battery consumption of each operation pattern operating from the battery consumption information shown in FIG. 4, and the operation function column stores the result of reading the actually operated function. Is. This battery change information stores the existing data as a history at the time of the next charge, and uses it as comparison data of the same operation pattern or calculates a reduction in operation time due to battery deterioration, etc., as will be described later. Used for correction when calculating the remaining time.

  Next, the battery remaining value calculation processing unit 244 (battery remaining value calculating means, output means) is the remaining predicted value of the battery at the current time (predicted remaining value), that is, the remaining capacity of the battery and the remaining driveable time ( The remaining time is calculated and output to the main LCD screen 11. The output of the calculation result is not limited to the main LCD screen 11 but may be a sub screen or may be output by sound or lamp lighting.

  Specifically, the battery remaining value calculation processing unit 244 reads the battery output voltage value at the read current time, the operation pattern, and the consumption stored in the battery consumption storage unit 313 corresponding to the battery output voltage value and the operation pattern. Based on the amount information and the battery output change information stored in the battery output change storage unit 312, the remaining battery capacity and the remaining battery time are calculated. An example of the calculation will be described with reference to the battery information screen shown in FIG. Note that FIG. 7A transitions to this screen by long pressing the MENU key from the function screen shown in FIG. At this time, as described above, the current output voltage value of the battery and the operation pattern in operation of the mobile phone 1 are detected, and the remaining battery capacity and remaining battery time are calculated. Here, it is assumed that the current time is 18:00, the current output voltage value of the battery is 3.8 V, and the operating pattern during operation is P7, P100, and P107.

  First, “battery information” in the uppermost row in FIG. 7A is the title of the screen, and the detailed information of the battery is displayed below it. “Battery partial” on the first line is a currently displayed battery icon and description of the icon, and “remaining capacity” on the second line is the calculated remaining battery capacity at the current time. As a calculation method, first, for example, when the battery voltage range in which the mobile phone 1 operates is 1.0 V from 4.3 V to 3.3 V, when the currently detected voltage is 3.8 V, (4 .3V-3.8V) /1.0V×100=50%. Subsequently, from the battery output change information of FIG. 5, since the time when the voltage became 3.8 V is 17:46, it is detected that 14 minutes have passed until 18:00 which is the current time. And since the battery consumption per hour of the operation pattern P7 + P100 + P107 operated for 14 minutes is 203, 14/60 × 203 = 47 is calculated. That is, the calculated value 47 represents the amount of battery consumption consumed from when the current output voltage value becomes 3.8 V to the current time. From the above, with respect to the maximum capacity 1000 shown in FIG. 4, the battery consumption is 10% from 50% of the remaining capacity of 3.8V to 40% of 3.7V from the battery consumption 100 per 0.1V. 47/100 × 100 = 47% is consumed, and the remaining capacity (50− (47/10)) = 45.3% can be calculated. This value is the ratio of the remaining battery capacity at the present time, and is displayed as shown in the second row of FIG. The “valid date” on the third line displays the time 17:16 displayed by “Battery partial” currently displayed among a plurality of existing icons.

  The “remaining time” on the fourth line displays the result of calculating the remaining time from the remaining battery capacity calculated as described above. For example, since the remaining battery capacity is calculated to be 45.3% as described above, the capacity of the maximum consumption 1000 × 45.3% = 453 is divided by the consumption of the operating pattern during operation. 453/203 = 2.2 hours are obtained as the remaining time. The remaining time may be calculated from the closest battery consumption and the operation pattern based on the operation pattern during the current operation and the remaining battery time information corresponding to each operation pattern shown in FIG. . In addition, the “operation pattern” on the fifth line displays the function currently being detected detected as described above.

  Further, the battery remaining value calculation processing unit 244 moves the cursor to each pattern by moving the cursor to the operation pattern field and pressing the left / right key on the battery information screen shown in FIG. Can be changed, deleted or edited. When the current operation pattern P7 + P100 + P104 in FIG. 7B is changed to the operation pattern P1 as shown in FIG. 7C, the changed operation pattern, the current output voltage value, Based on the stored consumption information and battery output change information, the battery capacity and remaining time, which are the remaining battery value, are calculated in the same manner as described above. Then, in the example of FIG. 7 (c), it can be seen that the calculated remaining time is extended from 2.2H to 94H, and the user registers the current remaining battery level and the mobile phone 1 without actually operating. Various operation patterns can be set in combination, and the remaining time in each operation pattern can be known. The operation pattern is such that the main function is always input, and only the subfunctions that can be set can be displayed and selected for the set main function. This function allows the user to know the function that maximizes or minimizes the remaining time by arbitrarily combining and setting the registered operation patterns of the mobile terminal. You can easily know whether the battery has until you return home even if you continue to listen to it, or whether the battery has it by changing the sub function while using the main function as it is in the current operation pattern Can do.

  Further, the remaining battery value calculation processing unit 244 always calculates the remaining battery capacity and remaining time as described above at regular time intervals, and based on the calculated remaining time, reaches the target time set by the user. It has a function of determining whether or not driving is possible and outputting the determination result. When it is determined that the battery does not have until the target date and time, for example, a battery information warning screen as shown in FIG. 6B is displayed. In the battery information warning screen, the user can change and set an operation pattern which is a function operated by the mobile phone 1. For example, as shown in the cursor position of FIG. 6B, the actual operation pattern is not changed by changing the operation pattern P7 to P1, but the remaining battery time when the operation pattern P1 is operated is temporarily changed. Is calculated. That is, as described above, based on the operation pattern set here, the current output voltage value, and the stored consumption information and battery output change information, the battery capacity and remaining time that are the remaining battery value are obtained. Is calculated.

  Further, the remaining battery value calculation processing unit 244 is actually stored in the battery output change storage unit 312 when the “correction mode” is set to be effective as shown in FIG. 7B by the setting processing unit 241 described above. Based on the battery output change information shown in FIG. 5 representing the state of the battery, the consumption information shown in FIG. 4 stored in the battery consumption storage unit 313 is corrected (stored). In other words, the difference between consumption information and remaining time information registered by default in the same set operation pattern and the measured data is checked, and if there is a difference, the default data is shown in FIG. It has a function to correct data. Specifically, in the operation pattern of P8, the consumption time from BT5 to BT4 is 0.2H by default, but when the actual measurement is 0.15H, the remaining battery time calculated thereafter is 0.15. By correcting the default data to /0.2=0.75 times, it is possible to correct it according to the deterioration of the battery.

[Operation]
Next, the operation of the mobile phone 1 having the above configuration will be described with reference to the flowcharts of FIGS. First, in each screen process (step S1), the mobile phone 1 checks whether, for example, the battery management function set on the battery setting screen shown in FIG. 7B is valid (step S2). If invalid (No in step S2), the existing battery voltage is periodically read, and a battery voltage periodic process for displaying a corresponding icon representing the remaining battery capacity on the screen is executed (step S3). . On the other hand, if it is valid (Yes in step S2), the battery voltage is read (voltage detection step), the operation pattern is extracted (operation pattern detection step), the battery output change information shown in FIG. The process proceeds to a battery management process for calculating the remaining value (step S4, battery remaining value calculating step, output step). Here, the detailed operation of the battery management process will be described with reference to FIGS. 9 and 10.

  FIG. 9 is a flowchart showing details of the battery management process (step S4). First, in the battery voltage process (step S20, voltage detection step), the current battery voltage reading process and the time when each voltage is reached are stored as shown in FIG. Subsequently, in the operation pattern detection process (step S21, operation pattern detection step), the main function and the sub function in operation are extracted and stored as shown in FIG. Here, the further detailed operation | movement of this operation | movement pattern detection process (step S21) is shown in the flowchart of FIG. First, the main function in operation is extracted, and main pattern processing for extracting the corresponding function from the main operation patterns P1 to P8 in FIG. 4 is executed (step S30). Similarly, a function effective as a sub-function is extracted, and sub-pattern processing for extracting sub-patterns from P100 to P105 is executed (step S31). Then, a combined battery consumption is calculated from the extracted operation pattern and FIG. 4, and a remaining time process (step S32 (step S22)) is performed to calculate the remaining time from the current time and the data of FIG. Is finished (step S33).

  Next, the description will be given returning to the remaining battery time process (remaining battery value calculation step) shown in step S22 of FIG. In the remaining battery time process (step S22), based on the output voltage value and the operation pattern detected in the battery voltage process (step S20) and the operation pattern detection process (step S21), the remaining capacity and the remaining time are calculated as described above. The calculated and extracted operation pattern is displayed on a battery information display screen as shown in FIG. 7A (output process). At this time, it is checked whether or not the target date and time for which the battery is desired to be held is set after the current time on the battery setting screen shown in FIG. 7B described later (step S23). Yes), it is checked whether or not the battery waits until the target date and time (step S24). If the battery has the calculated remaining time until the target date and time (Yes in step S24), the process returns to each screen process (step S1). On the other hand, if the battery does not have the target date and time (No in step S24), the process proceeds to battery information warning screen processing for displaying the battery information warning screen shown in FIG. 6B (step S25). Thereafter, it is checked whether or not the battery information warning screen is to be terminated, such as when the Back key is pressed (step S26). If the battery information is terminated, the process proceeds to a battery management termination process (step S27). When the operation pattern correction setting is performed on this battery information warning screen (operation pattern setting step), the remaining time is calculated based on the changed operation pattern (battery remaining value calculation step), The newly calculated remaining time is displayed (output process).

  Next, returning to step S5 in FIG. Here, in the function screen shown in FIG. 6 (a), has the MENU key been pressed for a long time to make a transition to the battery information display screen (FIG. 7 (a)) that displays the result of the battery management process (step S4)? Check (step S5). If the MENU key is pressed for a long time (Yes in step S5), the process proceeds to a battery information display process for displaying the battery information screen shown in FIG. 7A (step S6). In this battery information display process, first, the currently displayed battery icon, the icon description, and the time when the battery icon display becomes valid are read from the battery output change information of FIG. In the battery information display process (step S8), the remaining capacity, remaining time, and operation pattern calculated in the battery management process (step S4) described above are displayed (output process).

  Thereafter, it is checked whether or not to end the battery information display (step S9). If not (No in step S9), it is checked whether or not the battery setting is selected (step S10). If the battery setting is selected such as when the MENU key is pressed (Yes in step S10), the battery setting screen shown in FIG. 7B is displayed and the process proceeds to the battery setting process (step S11). In this battery setting screen, as described above, the validity / invalidity of the correction mode for correcting the difference between the validity / invalidity of the battery management function and the setting of the target date and time and the default data due to the deterioration of the battery is set. Can do. At this time, an operation pattern that particularly requires correction can be set.

  Thereafter, it is checked whether or not the battery setting is finished (step S12). If the battery key is finished such as pressing the Back key (Yes in step S12), the process returns to the battery information display process (step S6). On the other hand, on the battery information screen shown in FIG. 7A, it is checked whether or not the operation pattern editing process is performed (step S13). If the operation pattern is selected to be rewritten (Yes in step S13), FIG. A transition is made to the operation pattern editing process of the battery information display screen shown in (c) (step S14). Here, when the operation pattern is corrected and set (operation pattern setting step), the remaining time is calculated based on the changed operation pattern (battery remaining value calculation step), and the newly calculated remaining time is calculated. Time is displayed (output process). Thereafter, when the operation pattern editing process is completed (Yes in step S15), the process proceeds to a battery information display process (step S6).

  When the battery is set in step S11 and the correction mode is enabled, the battery is changed at any timing after the battery output change information is accumulated as shown in FIG. The output change information is stored as a history in another area and used as comparison data for the same operation pattern that has been set, or the operation time reduction due to battery deterioration or the like is calculated, and the consumption information in FIG. 4 is corrected ( This is used when calculating the remaining capacity and remaining time thereafter. For example, a difference between consumption information and remaining time information registered by default at a predetermined voltage value of a predetermined operation pattern and measured data is checked, and if there is a difference, default data (FIG. 4) is determined according to the difference. The consumption information shown in FIG. Accordingly, more accurate remaining time and the like can be calculated during subsequent battery management processing in response to battery deterioration and the like. If the difference is large, a display output may be made to notify the user that the battery has deteriorated.

  As described above, according to the mobile phone in the present embodiment, the current output voltage value of the battery and the operating pattern that is operating are detected, and these information, the battery consumption information stored in advance, Furthermore, based on the time-series change information of the stored output voltage value, the remaining capacity of the battery and the remaining drive time can be calculated and output. Specifically, by reading the time when the output voltage value of the battery became the current value, and calculating the capacity consumed in the operating pattern that is operating from this time to the current time, more accurate The remaining battery capacity can be calculated. Therefore, the remaining battery value of the mobile phone can be predicted with higher accuracy, and the user can recognize battery exhaustion more accurately. As a result, unexpected battery exhaustion can be avoided, and convenience for the user can be improved.

  In addition, since whether or not the battery has until a predetermined time is automatically calculated and the result is output, the user can easily recognize whether or not the battery has until the time desired by the user. Further improvement in convenience can be achieved.

  Furthermore, since the registered consumption information and remaining time information are automatically corrected according to changes due to actual battery deterioration, etc., a more accurate battery remaining value can be obtained in response to battery deterioration. Can be calculated. In addition, the user can be notified of the deterioration of the battery, and can be urged to replace the battery.

  In addition, since the user can arbitrarily set the operation pattern and calculate the remaining battery value, the user can know the duration of the battery in various situations. For example, settings such as holding the battery until the target time can be easily performed, and further convenience can be improved.
