  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram schematically showing a configuration of a mobile terminal 100 according to an embodiment of the present invention.

  The portable terminal 100 uses the secondary battery 200 as a driving power source. A secondary battery is a rechargeable battery that can be repeatedly charged and discharged. Secondary batteries include, for example, lithium ion batteries, lead acid batteries, nickel cadmium batteries, and nickel metal hydride batteries.

  The mobile terminal 100 is a terminal that can record (for example, record and / or record) broadcast content such as television broadcast and radio broadcast by specifying a start date and time and an end date and time in advance. The portable terminal 100 includes various terminals such as a cellular phone, a PDA (Personal Digital Assistance), a notebook computer, and a portable game device.

  As shown in FIG. 1, the mobile terminal 100 includes a recording schedule management unit 20, a recording unit 30, a remaining battery level detection unit 40, a battery capacity determination unit 50, and a charging schedule proposal unit 60. FIG. 1 also shows a secondary battery 200.

  The recording schedule management means 20 manages reservation information including the recording start date and time and the recording end date and time of a predetermined broadcast content. The recording schedule management means 20 may have a recording schedule table.

  FIG. 2 is an example of a recording schedule table for recording a television broadcast. The recording schedule table shown in FIG. 2 includes, for example, information of recording start date / time, recording end date / time, channel, recording mode, priority, and program name for which recording is desired. The recording mode is a mode for setting how much image quality is recorded. In FIG. 2, the recording mode has, for example, three stages of High (high), Middle (middle), and Low (low). The battery capacity required for recording differs depending on the recording mode. The higher the recording mode, the more battery capacity is required for recording. The priority is an order given in descending order of necessity of recording. In FIG. 2, the priority has three levels of high, medium, and low.

  The recording schedule management means 20 may have a recording reservation function using EPG (Electric Program Guide (electronic program guide, registered trademark)). If an EPG recording reservation function is provided, for example, a broadcast program table automatically distributed is displayed, and a recording start date and a recording end date and time of a predetermined broadcast content are included only by selecting a program name to be recorded. Reservation information can be acquired.

  The recording unit 30 is connected to the recording schedule management unit 20. The recording unit 30 records predetermined broadcast content based on an instruction from the recording schedule management unit 20. That is, the recording unit 30 has a function of recording a predetermined broadcast content from the recording start date and time to the recording end date and time included in the reservation information of the recording schedule management unit 20. The recording means 30 includes at least an application for recording broadcast content, but does not need to include a storage device. As the storage device, a recording medium (for example, a memory card) that can be replaced with a portable terminal can be used. The memory card includes, for example, a compact flash (registered trademark), smart media, an SD (registered trademark) memory card, and a memory stick.

  Of course, the recording means 30 may include a recording device. For example, when a portable terminal has a built-in memory or a built-in hard disk as a storage device, predetermined broadcast content can be recorded in the built-in memory or built-in hard disk.

  FIG. 3 is a flowchart for explaining an example of the charging process of the secondary battery 200 of the mobile terminal 100. Hereinafter, the remaining battery level detection means 40, the battery capacity determination means 50, the charging schedule proposal means 60, and the charging process using these will be described with reference to FIGS.

  In addition, the timing which performs the charging process of the secondary battery 200 demonstrated below is not specifically limited. For example, it is performed immediately after recording a predetermined broadcast content. Thereby, a charge schedule can be known at the time of reservation. Or you may perform regularly every predetermined time (for example, every 3 hours). Or after charging of a portable terminal is complete | finished or after applications, such as a game currently performed with the portable terminal, are complete | finished. Moreover, you may perform when the charge of the secondary battery 200 is completed. When the mobile terminal of this embodiment is applied to a mobile phone, it may be performed when the call is finished. Based on the above, it is possible to know a more reliable charging schedule that reflects the change in the battery capacity of the secondary battery 200.

  As shown in FIG. 1, the battery remaining amount detection means 40 is connected to the secondary battery 200. In step S <b> 502 of FIG. 3, the battery remaining amount detection unit 40 detects the current remaining capacity (A) of the secondary battery 200. The battery remaining amount detection means 40 includes, for example, a voltage measurement circuit. Based on the difference between the charging voltage value (unit: volt (V)) and the discharging voltage value (unit: volt (V)) of the secondary battery 200 detected by the voltage measuring circuit, the battery remaining amount detecting means 40 The current remaining capacity (unit: coulomb (C)) of the secondary battery 200 is calculated in real time.

  As shown in FIG. 1, the battery capacity determination unit 50 is connected to the remaining battery level detection unit 40 and the recording schedule management unit 20.

  In step S504 and step S506 in FIG. 3, the battery capacity determination unit 50 determines the required recording capacity (B) of the secondary battery required for recording a predetermined broadcast content based on the reservation information managed by the recording schedule management unit 20. Then, the expected use capacity (C) of the secondary battery used by the recording start date and time is calculated.

  Hereinafter, the calculation method of the required recording capacity (B) of the secondary battery required for recording the predetermined broadcast content and the expected usage capacity (C) of the secondary battery used by the recording start date and time will be described more specifically. To do.

  First, a method for calculating the required recording capacity (B) will be described.

  The battery capacity determination unit 50 calculates the recording time from the recording start date and time and the recording end date and time included in the reservation information managed by the recording schedule management unit 20. The reservation information managed by the recording schedule management means 20 is obtained from, for example, the recording schedule table illustrated in FIG. The recording time is multiplied by the first average battery capacity, and the required recording capacity (B) of the secondary battery required for recording the predetermined broadcast content is calculated (S504). The first average battery capacity refers to the battery capacity (C / s) required per hour for recording a predetermined broadcast content. The first average battery capacity is, for example, a battery capacity required per hour to receive predetermined broadcast content, a battery capacity (C / s) required per hour to write data of the predetermined broadcast content on a recording medium, And the battery capacity required per hour to turn on the mobile terminal. The battery capacity required per hour to turn on the power of the mobile terminal is, for example, the battery capacity required per time when the mobile phone terminal is in a standby state (a state where a telephone can be transmitted and received at any time).

  The first average battery capacity is set in the mobile terminal when the mobile terminal is shipped from the factory, for example. Alternatively, the battery capacity determination unit 50 may have a predetermined calculation routine and appropriately calculate the first average battery capacity. For example, the battery usage capacity of a portable terminal in a standby state is detected for a predetermined time, and the battery usage capacity is divided by the predetermined time to calculate the first average battery capacity.

  When calculating the required recording capacity (B), the recording schedule of the recording schedule management means 20 may be taken into consideration. Specifically, for example, when the recording schedule management means 20 has the recording schedule table shown in FIG. 2, the recording mode is set so that the first average battery capacity decreases in the order of High, Middle, and Low.

  Next, a method for calculating the planned use capacity (C) will be described.

  The battery capacity determination means 50 multiplies the time from the current date and time to the recording start date and time by the second average battery capacity, and uses the expected capacity (C of the secondary battery used from the current date and time to the recording start date and time). ) Is calculated (S506). The second average battery capacity refers to the battery capacity (C / s) required per hour to turn on the mobile terminal. The second average battery capacity is set to the mobile terminal when the mobile terminal is shipped from the factory, for example, similarly to the first average battery capacity described above. Alternatively, the battery capacity determination unit 50 may have a predetermined calculation routine and appropriately calculate the second average battery capacity.

  In the case where recording of a plurality of broadcast contents is included in the reservation information of the recording schedule management means 20, and the estimated usage capacity (C) of the secondary battery for the second and subsequent recordings is calculated. It is preferable to appropriately use both the first average battery capacity and the second average battery capacity.

  As described above, the battery capacity determination unit 50 calculates the required recording capacity (B) of the secondary battery required for recording the predetermined broadcast content (S504), and determines the secondary battery used by the recording start date and time. The planned use capacity (C) is calculated (S506).

  In step S508 of FIG. 3, the battery capacity determination unit 50 determines whether or not the secondary battery needs to be charged in order to record predetermined broadcast content.

  That is, the battery capacity determination means 50 includes the required recording capacity (B) of the secondary battery required for recording the predetermined broadcast content, and the expected usage capacity (C) of the secondary battery used by the recording start date and time. Using the current remaining capacity (A) of the secondary battery obtained by the remaining battery capacity detection means 40, the difference between the current remaining capacity (A) of the secondary battery (A) and the expected capacity (C) (A− C) is calculated, and the difference (A−C) is compared with the required recording capacity (B). As a result of the comparison, it is determined whether or not the difference (A−C) is smaller than the required recording capacity (B).

  When it is determined that the difference (A−C) is smaller than the required recording capacity (B) ((A−C) <B) (S508: Yes), the predetermined broadcast content is completely recorded from the recording start date and time to the recording end date and time. It is determined that the secondary battery 200 must be charged in order to record data. In this case, the battery capacity determination unit 50 calculates the shortage capacity (B- (AC)) of the secondary battery 200 in step S510 of FIG. As will be described later, the insufficient capacity of the secondary battery 200 may be calculated as B-A.

  On the other hand, the battery capacity determination means 50 compares the difference (A−C) with the required recording capacity (B), and the difference (A−C) is greater than or equal to the required recording capacity (B) ( When it is determined that (A−C) ≧ B) (S508: No), it is determined that the predetermined content can be completely recorded from the recording start date to the recording end date without charging the secondary battery 200. . In this case, since it is determined that charging of the secondary battery 200 is unnecessary, the process proceeds to step S516, and the portable terminal 100 waits until the recording start date and time.

  The battery capacity determination unit 50 does not have to calculate the scheduled use capacity (C) of the secondary battery used from the current date and time to the recording start date and time. That is, step S506 in FIG. 3 may not be performed. In this case, the battery capacity determination means 50 compares the remaining capacity (A) with the required recording capacity (B) in step S508, and the current remaining capacity (A) of the secondary battery is greater than the required recording capacity (B). It is also determined whether or not the

  When it is determined that the remaining capacity (A) is smaller than the required recording capacity (B) (A <B), the secondary battery 200 is charged to record the predetermined broadcast content from the recording start date to the recording end date. Judge that it must be. In this case, the battery capacity determination unit 50 calculates the shortage capacity (BA) of the secondary battery 200 in step S510 of FIG.

  On the other hand, if it is determined that the remaining capacity (A) is greater than or equal to the required recording capacity (B) (A ≧ B), it is necessary to record a predetermined broadcast content from the recording start date to the recording end date. Since it is determined that charging of the secondary battery 200 is unnecessary, the mobile terminal 100 waits until the recording start date and time.

  The above processing method that does not take into account the planned use capacity (C) is less accurate than the processing method shown in FIG. However, since the expected use capacity (C) is much smaller than the required recording capacity (B) (C << B), the above processing method roughly approximates the necessity of charging when recording broadcast content. Is sufficient and has a merit that the determination method is simple.

  Next, the charging schedule proposing means 60 proposes the charging start date and time of the insufficient capacity so that the charging of the insufficient capacity is completed by the recording start date and time in steps S512 and S514.

  Hereinafter, the method for proposing the charging start date will be described more specifically.

  As described above, before the charging start date and time is proposed, the battery capacity determination means 50 preliminarily has the shortage capacity (B- (A-C)) or (B-A) of the secondary battery 200 in step S510 of FIG. Is calculated.

  As shown in FIG. 1, the charging schedule proposal unit 60 is connected to the battery capacity determination unit 50. The charging schedule proposing means 60 calculates the time required to charge the shortage capacity as shown in step S512 of FIG. The required charging time is obtained, for example, by dividing the shortage capacity by the charging capacity per unit time of the secondary battery 200 (unit: C / s). The charging capacity per unit time of the secondary battery 200 is set to a value specific to the type of secondary battery to be used, for example.

  Next, in step S514 of FIG. 3, based on the required charging time obtained in step S512, a charging start date and time for insufficient capacity is proposed so that charging of the insufficient capacity is completed by the recording start date and time. That is, the charging schedule proposing means 60 proposes the date and time before the charge required time of the insufficient capacity as the charging start date and time from the recording start date and time at the latest. When the time from the current date and time to the recording start date and time is longer than the charging time required for the insufficient capacity, the charging schedule proposing unit 60 may propose the current date and time as the charging start date and time.

  The charging schedule proposing means 60 may propose the charging start date and time and / or the charging end date and / or the required charging time.

  The charging schedule proposing means 60 may create a charging schedule table that describes the charging start date and time. An example of the charging schedule table is shown in FIG. The charging schedule table of FIG. 4 includes information on charging start date and time, charging end date and time, and required charging time.

  As explained above, the charging schedule proposing means 60 proposes the charging start date and time of the insufficient capacity.

  In the flowchart shown in FIG. 3, each step is performed in the order of steps S502, S504, and S506. However, the order in which steps S502, S504, and S506 are performed is not limited to this, and may be performed in any order.

  As described above, the mobile terminal 100 according to the present invention is not capable of recording a predetermined broadcast content due to insufficient capacity of the secondary battery 200. The charging start date and time of the insufficient capacity can be proposed. Therefore, the user of the portable terminal can charge the secondary battery prior to the recording start date and time according to the above proposal, and can suppress the failure to record broadcast content due to insufficient battery capacity.

  The portable terminal 100 of the present invention may further include a charging schedule presentation unit that presents the charging start date and time proposed by the charging schedule proposal unit 60. The charging schedule presentation unit has a function of presenting the charging start date and time proposed by the charging schedule proposal unit 60. The charging schedule presenting means may further present a charging end date and time.

  The charging schedule presentation means includes, for example, a display element such as a liquid crystal display or an organic EL display. The display element can present the charging start date and time to the user by, for example, character display. The display element can display the charging start date and time a predetermined time before the charging start date and time. In the following description, a date and time that is a predetermined time before the charging start date and time may be referred to as an alarm date and time.

  FIG. 5 illustrates a charging schedule presentation unit using a display element. FIG. 5A illustrates a display screen of a display element in a standby state. As shown in FIG. 5 (b), the display element displays on the display screen 5 minutes before the charging start date and time, “5 minutes remaining until the start of charging. Please prepare for charging.” Display the start date and time and the charging end date and time.

  The user of the portable terminal can know the charging start date and time proposed by the charging schedule proposing means 60 by looking at the above display, and can charge the secondary battery at the charging start date and time. The battery can be charged before the start date and time. As a result, it is possible to more reliably suppress the failure to record broadcast content due to insufficient battery capacity.

  In addition, if the charging start date and time is presented to the user using a pop-up, the user's attention can be drawn, so that it is possible to more reliably prevent the broadcast content from being missed due to insufficient battery capacity.

  Further, the charging schedule presentation unit may include a speaker. The speaker can present the charging start date and time to the user by voice. In addition, for example, if a sound (for example, a warning sound) is sounded a predetermined time before the charging start date and time, the user's attention can be drawn, so that the broadcast content cannot be recorded more reliably due to insufficient battery capacity. Can be suppressed.

  The charging schedule presentation unit may create a presentation schedule table including information on the charging start date and time. An example of the presentation schedule table is shown in FIG. The presentation schedule table of FIG. 6 includes information of presentation date and time, presentation items, presentation method, and processing results.

  Examples will be described below. Hereinafter, a mobile phone terminal will be exemplified to describe a mobile terminal according to an embodiment of the present invention, but the present invention is not limited to this.

  FIG. 7 is a block diagram schematically showing the configuration of the mobile phone terminal 102.

  The mobile phone terminal 102 includes at least a lithium ion battery 202 as a driving power source. In addition, the mobile phone terminal 102 can receive a television broadcast and record the received broadcast content on the memory card 300. The memory card 300 is a recording medium that can be replaced with the mobile terminal 102. FIG. 7 also shows the lithium ion battery 202 and the memory card 300. In the mobile phone terminal 102 of FIG. 7, components having the same functions as those of the mobile terminal 100 shown in FIG.

  The mobile phone terminal 102 includes a recording schedule management unit 20, a recording unit 30, a remaining battery level detection unit 40, a battery capacity determination unit 50, a charging schedule proposal unit 60, a charging schedule presentation unit 80, and a broadcast reception unit. 90.

  The recording schedule management means 20 has a recording schedule table 22 (see FIG. 2) including information on the recording start date and time and the recording end date and time.

  Broadcast receiving means 90 is connected to recording means 30 and recording schedule management means 20. The broadcast receiving unit 90 includes an antenna 92 for receiving a television broadcast, and a tuner 94 for performing predetermined signal processing on the received broadcast signal and outputting it to the recording unit 30. The broadcast receiving means 90 receives predetermined broadcast content based on the reservation information of the recording schedule management means 20.

  The recording unit 30 is connected to the memory card 300, the recording schedule management unit 20, and the broadcast receiving unit 90. The recording unit 30 records the predetermined broadcast content received by the broadcast receiving unit 90 on the memory card 300 based on the reservation information of the recording schedule management unit 20.

  As described with reference to FIG. 3, the battery capacity determination unit 50 determines whether or not the remaining capacity of the battery 202 is insufficient to record predetermined broadcast content on the memory card 300. When the battery capacity determination unit 50 determines that the remaining capacity is insufficient, the charge schedule proposal unit 60 proposes a charge start date and time. The charging schedule proposing means 60 has a charging schedule table 62 (see FIG. 4) that describes the charging start date and time and the charging end date and time.

  The charging schedule presentation unit 80 includes a display element 82 and a speaker 84. Moreover, the charging schedule presentation means 80 has a presentation schedule table 86 (see FIG. 6) including information on the charging start date and time.

  The charging schedule presentation unit 80 is connected to the charging schedule proposal unit 60. The charging schedule proposing means 60 has a function of measuring time, and determines whether or not the charging start date / time, the charging end date / time, the alarm date / time, etc. have been reached. When the current date and time has reached the date and time, the charging schedule proposal unit 60 notifies the charging schedule presentation unit 80 to make a predetermined presentation. The charging schedule presentation unit 80 makes a predetermined presentation using the display element 82 and the speaker 84 based on the notification.

  Hereinafter, a broadcast content recording method using the mobile phone terminal 102 will be described with reference to the flowchart shown in FIG.

  In step S202, the charging schedule proposing means 60 determines whether or not the alarm date and time (here, for example, 5 minutes before) has been reached. If it is determined that the alarm date has been reached (S202: Yes), the process proceeds to step S204. If it is determined that the alarm date has not been reached (S202: No), the process proceeds to step S202 again.

  In step S <b> 204, upon receiving the notification of the charging schedule proposal unit 60, the charging schedule presentation unit 80 sounds a warning sound using the speaker 84 and performs the display shown in FIG. 5 using the display element 82.

  In step S206, the charging schedule proposal unit 60 determines whether or not the charging start date and time has been reached. When it is determined that the charging start date / time has been reached (S206: Yes), the process proceeds to step S208. When it is determined that the charging start date / time has not been reached (S206: No), the process proceeds to step S206 again.

  When it is determined that the charging start date and time has been reached (S206: Yes), if the battery 202 is charged in step S208 (S208: Yes), the process proceeds to step S212. In step S208, if the battery 202 is not charged (S208: No), the process proceeds to step S210.

  In step S212, the battery remaining amount detecting means 40 determines whether or not the battery capacity sufficient to record the predetermined broadcast content from the recording start date and time to the end date and time is charged. Information relating to recording such as the recording start date and time and the recording end date and time is managed by the recording schedule management means 20. When it is determined that a sufficient battery capacity is charged, the process proceeds to step S214. If it is determined that the charging is not sufficient, the process proceeds to step S212 again.

  In step S214, the remaining battery level detection means 40 notifies the battery capacity determination means 50 that the charging has been completed. The battery capacity determination unit 50 sends the notification to the recording schedule management unit 20. Receiving the notification, the schedule management means 20 instructs the recording means 30 to record the predetermined broadcast content on the memory card 300 based on the reservation information described in the recording schedule table.

  In step S <b> 216, the recording unit 30 records the predetermined broadcast content received by the broadcast receiving unit 90 on the memory card 300 based on an instruction from the schedule management unit 20.

  In step S208, if the battery 202 is not charged (S208: No), the process proceeds to step S210. In step S210, the recording schedule managed by the recording schedule management means 20 can be changed. The recording schedule may be changed by the user of the mobile terminal or automatically by the recording schedule management means 20.

  The change of the recording schedule includes, for example, stop of recording and change of recording start time and / or end time. It also includes lowering the recording mode that was initially set (for example, changing from High to Low, see FIG. 2). When the recording schedule management unit 20 automatically changes the recording schedule, for example, the recording of broadcast content with a lower priority (included in the reservation information of the recording schedule management unit, see FIG. 2) is selectively stopped. Or the recording mode can be lowered. When the recording schedule is changed, the process proceeds to step S202.

  As described above, the mobile phone terminal 102 according to the present embodiment roughly determines whether or not the remaining capacity of the secondary battery is insufficient in order to record predetermined broadcast content, and is insufficient. If it is determined, the charging start date and time is proposed so that the charging is completed by the recording start date and time of the broadcast content, so that it is possible to suppress the failure to record the broadcast content due to insufficient capacity of the secondary battery.

  The present invention is suitably used for various terminals such as a mobile phone, a PDA, a notebook personal computer, and a portable game device capable of recording broadcast contents using a secondary battery as a driving power source.
