In the description of the present invention, "battery usage time information" is information indicating an available current consumption of the portable terminal and the available time of the battery unit according to the remaining charge of the battery unit.

For example, the usable time (H) of the battery is proportional to the remaining battery charge (mAH) and inversely proportional to the average current consumption (mA). It is assumed that the current portable terminal continuously consumes 300 mA of current, and the remaining charge of the battery is 2100 mAH. In this case, when the portable terminal does not generate energy loss due to external factors (temperature, resistance, etc.), the remaining charge of 2100 mAH is consumed after about 7 hours.

In this way, information showing a correlation between the average current consumption and the usable time according to the remaining battery charge is referred to as "battery use time information."

In addition, the description of the present invention includes an embodiment in which the average current consumption, available time, and a notification message (for example, "current current consumption is abnormal") are displayed when the average current consumption is abnormal.

The present invention includes an embodiment of displaying an average current consumption and an available time, and displaying a notification message when the available time is less than a preset threshold time.

For example, when the user sets the threshold time to 10 minutes, and the available time of the battery remains less than 10 minutes, the portable terminal may display a notification message (for example, “Battery usage time is 10”). Minutes are left ".

The average current consumption displayed on the screen is characterized in that the average current consumption for a specific time. The average current consumption is preferably calculated by measuring the current consumption at each set period and dividing the measured current consumption by an average value according to the measurement frequency.

The user who checks the notification message then turns off the portable terminal in anticipation of reducing the brightness of the LCD (Liquid Crystal Display) window, changing the call alert notification method from vibration to the lamp, or making an important call. (Off) reduces the power consumption to prepare for battery discharge. The notification message may be displayed on the screen in the form of a pop up, slide, overlay, or output in voice.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a view showing a schematic configuration of a portable terminal according to an embodiment of the present invention.

Referring to FIG. 1, the portable terminal includes a communication unit 110, an input unit 120, a display unit 130, a storage unit 140, a battery unit 150, a current consumption measurement unit 160, and a controller 170. Include.

The communication unit 110 may include a radio frequency (RF) transmitter for upconverting and amplifying a frequency of a transmitted signal, and an RF receiver for low noise amplifying and downconverting a received signal.

The input unit 120 may be formed of a touch pad or a keypad including various function keys, numeric keys, special keys, text keys, and the like, by a user to control the operation of the portable terminal. The input signal is transmitted to the controller 170. In particular, in the present invention, the input unit 120 receives a setting signal for setting the threshold time from the user and transmits it to the control unit 170.

The display unit 130 may be formed of a liquid crystal display (LCD) or the like, and displays various display data generated in the portable terminal and an operation state of the current portable terminal on the screen. In particular, the display unit 130 of the present invention displays the average current consumption, available time and notification message under the control of the controller 170.

The storage unit 140 stores programs and data necessary for the overall operation of the portable terminal according to an embodiment of the present invention. In particular, in the present invention, the storage unit 140 stores the battery usage time information 141 as shown in Table 1 below.

TABLE 1

The battery usage time information 141 is information stored by matching the average current consumption of the current portable terminal with the available time according to the remaining battery charge of the battery unit 150, as shown in Table 1. to be. The battery usage time information 141 may be stored in the form of a database as shown in Table 1. For example, if the current portable terminal consumes 400 mA of current on average, and the remaining battery charge of the battery unit 150 is 2.07 mAH, the battery unit 150 is expected to discharge after about 5 minutes.

The battery unit 150 converts the AC power (110V or 220V) received from the power source into a DC power source to charge the charge, converts the charged amount of charge into a voltage, and transfers it to the control unit 170. To this end, the battery unit 150 preferably includes an AC adapter 151, a charging circuit 152, and an A / D converter 153.

The AC adapter 151 converts AC power (110V and 220V) received from a power source into DC power, and the charging circuit 152 charges through the AC adapter 151 connected to the AC power sources 110V and 220V. To charge.

In addition, the A / D converter 153 is connected to the charging circuit 152 converts the amount of charge charged into a voltage and transfers it to the controller 170.

The current consumption measuring unit 160 measures the current consumption of the battery unit 150. In addition, the measurement of the current consumption is preferably measured for each predetermined current measurement period. The current consumption measurer 160 converts the measured current consumption into a voltage having a magnitude that can be recognized by the current consumption determiner 171 included in the controller 170 and transmits the current to the controller 170. When the voltage converted and amplified by the current consumption measurer 160 is applied to the controller 170, the controller 170 calculates the original battery current consumption, calculates an average of these values (average current consumption), It is displayed on the display unit 130 of the terminal.

The controller 170 performs an overall control operation of the portable terminal.

In particular, in the present invention, the controller 170 calculates an average value of the current currently consumed by the battery unit 150 and determines the available time according to the remaining charge of the battery unit 150. To this end, the controller 170 preferably includes a current consumption determiner 171 and a use time determiner 172.

The current consumption determiner 171 calculates a voltage before amplification of the voltage value received from the current consumption measurer 160, and determines the current consumption of the battery unit 150 using the calculated voltage. .

In addition, the usage time determining unit 172 uses the average current consumption and the remaining charge amount (a value indicating the charge amount as a voltage) received from the A / D converter 153 of the battery unit 150. Determine the possible time. In this case, the available time may be used by using the battery usage time information 141 stored in the storage 140.

The controller 170 displays the current consumption determined by the current consumption determiner 171 and the available time determined by the usage time determiner 172 on the display 130.

When the average current consumption is abnormal (first embodiment), the controller 170 outputs a notification message indicating that the average current consumption, the available time, and the amount of consumption are abnormal.

When the threshold time is set in the portable terminal (second embodiment) and the determined available time is less than the threshold time, the controller 170 outputs a notification message indicating that the available time is short.

2 is a diagram illustrating a method of displaying a current consumption and a usable time of a portable terminal according to a first embodiment of the present invention.

In particular, FIG. 2 illustrates an embodiment of a portable terminal in which a mode for displaying an average consumption amount and a usable time is set when the average current consumption of the portable terminal is abnormal.

1 and 2, the controller 170 controls the current consumption measuring unit 160 to measure current consumption of the battery unit 150 (S201). The measurement of the current consumption is preferably measured for each predetermined current measurement period.

The current consumption measurement unit 160 converts the measured current consumption into a voltage value of a magnitude that can be recognized by the current consumption determination unit 171 included in the control unit 170 and transmits it to the controller 170.

Then, the controller 170 calculates an average current consumption of the current consumption measured by the current consumption measurement unit 160 (S203).

The controller 170 determines whether the average current consumption calculated in step S203 is normal or abnormal using the battery usage time information 141 (see Table 1) stored in the storage 140. It is determined (S205).

For example, when the average current consumption of the current consumption measured by the current consumption measurer 160 is 150 mA, the controller 170 determines the average current consumption of 150 mA as normal (see Table 1). However, if the average current consumption of the current consumption is 210mA, the controller 170 determines that the average current consumption of 210mA is abnormal.

If the determination result of step S205 is abnormal, the control unit 170 checks the remaining charge of the battery unit 150 by using the charging voltage received from the battery unit 150 (S207).

Then, the control unit 170 displays the available time according to the average current consumption measured in step S203 and the battery charge remaining amount calculated in step S207 in the battery usage time information 141 stored in the storage unit 140. Check (S209). For example, assuming that the average current consumption calculated by the controller 170 is 210 mA and the remaining battery charge calculated in step S207 is 2.07 mAH, the available time of the battery unit 150 is about 20 minutes. to be. This means that the battery unit 150 is discharged after about 20 minutes unless the user removes the cause of abnormally consuming the current.

Then, the control unit 170 displays the average current consumption measured in step S203 and the available time checked in step S209 on the display unit (S211). In this case, it is preferable to output a notification message together so that the user can know the abnormal current consumption.

Then, the control unit 170 displays a screen for receiving a selection signal asking the user whether to change the current mode to the power saving mode (S213).

Then, the controller 170 determines whether a signal for requesting the mode change of the portable terminal to the power saving mode is input (S215).

When the mode change request signal is inputted as a result of the determination in step S215, the controller 170 changes the mode of the portable terminal to the power saving mode (S217).

Then, the control unit 170 returns to step S201 to repeat the process.

If the mode change request signal is not inputted as a result of the determination in step S215, the control unit 170 returns to step S201 and repeats the process.

Then, it is determined whether the average current consumption calculated through the steps S201 and S203 is normal or abnormal (S205). If the determination result of step S205 is normal, the controller 170 performs a corresponding function (S206). The corresponding function includes a function of erasing the average current consumption and usable time previously displayed (S211).

In particular, FIG. 3 illustrates an embodiment in which a battery usage threshold time is set in a portable terminal displaying an average current consumption and an available time.

1 and 3, the controller 170 controls the current consumption measuring unit 160 to measure current consumption of the battery unit 150 at step S301. The measurement of the current consumption is preferably measured for each predetermined current measurement period.

Then, the current consumption measurement unit 160 converts the measured current consumption into a voltage having a magnitude that can be recognized by the current consumption determination unit 171 included in the control unit 170 and transmits it to the control unit 170.

Then, the controller 170 calculates an average current consumption of the current consumption measured by the current consumption measurement unit 160 (S302).

Then, the controller 170 checks the remaining charge level using the charging voltage received from the battery unit 150 (S303).

Then, the control unit 170 displays the available time according to the average current consumption measured in step S302 and the battery charge remaining amount calculated in step S303 in the battery usage time information 141 stored in the storage unit 140. Check (S305).

Then, the control unit 170 displays the average current consumption calculated in step S302 and the available time checked in step S305 on the display unit 130 (S307).

Then, the controller 170 determines whether the available time determined in step S305 is less than or equal to a preset threshold time (S309).

As a result of the determination in step S309, if the available time determined in the step S305 is greater than the preset threshold time, the control unit 170 returns to the step S301 to measure the current consumption and repeat the above steps. .

As a result of the determination in step S309, if the available time determined in step S305 is less than or equal to a preset threshold time, the controller 170 determines that the user currently consumes the current abnormally. A notification message is outputted so that it can be performed (S311). The content of the notification message output in step S311 is preferably a content indicating that the usage time of the battery unit is short.

Then, the control unit 170 displays a screen for receiving a selection signal asking the user whether to change the current mode to the power saving mode (S313).

Then, the control unit 170 determines whether a signal for requesting a change of the mode of the portable terminal to the power saving mode is input (S315).

As a result of the determination in step S315, when the mode change request signal is input, the controller 170 changes the mode of the portable terminal to the power saving mode (S317). Then, the control unit 170 returns to step S301 to repeat the process.

When the mode change request signal is not input as a result of the determination in step S315, the control unit 170 returns to step S301 and repeats the above process.

 4 is a diagram illustrating an example of a screen displaying current consumption and usable time of a portable terminal according to the embodiment of FIG. 2. In particular, FIG. 4 is a diagram illustrating an example of a case in which an abnormal current (for example, 450 mA) is consumed for some reason while consuming a current in a normal range.

Reference numeral 410 denotes a screen example when the average current consumption measured by the controller 170 is in a normal range. In addition, reference numeral 420 indicates an average current consumption (for example, 210 mA) and an available time (for example, 20 minutes) on the display unit 130 when the average current consumption (for example, 210 mA) is out of the normal range. One screen example.

In the battery usage time information stored in the storage 140, the average current consumption in the range of "100 mA to 199 mA" is referred to as a normal consumption (see <Table 1>).

Then, the controller 170 outputs a message indicating that an abnormal current is currently consumed in the portable terminal as shown by reference numeral 430. There can be many reasons for abnormal current consumption. The cause may be, for example, a case where the portable terminal exists in a low temperature environment, located in a shadow area of a received signal, or exists in an excessive handover area. However, the causes are often not removed by the user's will. In this case, the controller 170 preferably displays a screen for inputting a user's selection signal for confirming whether or not the portable terminal is changed to the power saving mode as shown by reference numeral 430.

At this time, when the user inputs a setting change request signal to the power saving mode, the controller 130 changes the mode of the portable terminal to the power saving mode as indicated by reference numeral 440. The power saving mode may include decreasing the brightness of the LCD window, changing the method of receiving notification of telephone calls and text messages to silence, and extending the channel search period. When the power saving mode is set in the portable terminal, as shown by reference numeral 440, the average current consumption is reduced to 180 mA to restore the normal range, and the usable time may be extended to 40 minutes. Since the consumption current of the portable terminal is restored to the normal range, the controller 170 deletes the average consumption current and the available time from the display unit 130 as shown by reference numeral 450.

In particular, FIG. 5 illustrates an embodiment in which the battery usage threshold time is set to 10 minutes in the portable terminal displaying the average current consumption and the available time.

The control unit 170 displays the average consumption current (for example, 450 mA) and the available time (for example, 11 minutes) according to the remaining battery charge, as shown by reference numeral 510, on the display unit 130.

When the displayed available time is changed to 10 minutes, which is a usage threshold time, the controller 170 outputs a notification message so that the user may know that the battery available time is less than or equal to the set threshold time (520). At this time, in case the user must use the portable terminal due to the discharge faster than expected (rescue request during winter hiking, emergency call), the control unit 170 in the power saving mode as shown by reference numeral 520 It is preferable to display the input screen of the user's selection signal to confirm whether or not to change the setting. At this time, when the user inputs a setting change request signal to the power saving mode, the controller 130 changes the mode of the portable terminal to the power saving mode as indicated by reference numeral 530. The power saving mode may include reducing the brightness of the screen window, changing the reception notification method of a phone call and a text message to a silent mode, and extending a null search period. When the power saving mode is set in the portable terminal, as shown by reference numeral 530, the average current consumption is reduced from 450mA to 320mA, so that the usable time is extended from 10 minutes to 40 minutes.

In the description of the present invention, only an embodiment of changing the current mode to the power saving mode according to the user's selection when the current consumption is abnormal or when the available time of the battery unit 150 is less than the threshold time will be described.
