Description

  The present invention relates to a charging device and a program capable of connecting a plurality of electronic devices as charging targets.

  In recent years, as a charging device capable of simultaneously charging a plurality of electronic devices such as a mobile phone, a wired connection type charging device having a plurality of connectors and a non-contact type charging device adopting an electromagnetic induction method are known. Yes. In this type of charging device, if a plurality of electronic devices are charged at the same time, the power is equally divided by the plurality of electronic devices, so that sufficient power is not supplied to each electronic device. For this reason, in the past, non-contact charging was performed by deciding the electronic device that gives the highest priority to charging based on the remaining battery capacity ratio among a plurality of electronic devices and charging only the electronic device with the highest priority. An apparatus is known (see Patent Document 1).

JP 2007-089341 A

  However, in the above-described prior art, charging is performed for an electronic device that is alternatively selected from a plurality of electronic devices, and there is a complicated circuit for obtaining the remaining battery ratio. There was a problem that it was necessary on the electronic device side or the charging device side. In addition, it may not always be a good idea to give top priority to an electronic device with the smallest remaining battery level. For example, when the remaining battery level of the electronic device A is about 1/4 and the remaining battery level of the other electronic device B is about 1/5, the user of the electronic device B has no particular plans to go out. Even when the user A is scheduled to go out after 1 hour, charging of the electronic device B with less battery power is given the highest priority, so charging to the electronic device A is not performed at all or insufficient. In some cases, it was possible to go out, and there could be a situation where the battery level was low (battery was exhausted) while on the go.

  Similarly, although the way of charging varies greatly depending on the user, even in such a case, giving priority to an electronic device with the least remaining battery power may not always be a good idea. For example, a user who frequently uses a heavy load function such as a TV broadcast receiving function tries to charge the battery even when the remaining battery level of the electronic device is about 2/3. If there is an electronic device with a remaining charge of about 1/2, it will be given priority, and it may be said that it is in line with the actual situation, such as when there is no remaining battery power while using the TV broadcast reception function. There wasn't.

(First embodiment)
The first embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is an external view showing a charging device to which a plurality of electronic devices can be connected as charging targets.
The charging device 1 has a box shape as a whole, and has a plurality of connectors (not shown) so that a plurality of electronic devices 2 can be connected, and a management device (such as a personal computer or an audiovisual device). 3 can be connected via a cable 4a. The charging device 1 is connected to a commercial power source (not shown) via the cable 4b, but is not limited thereto, and may be connected to the management device 3 as a power source. A display screen DP is disposed on the front surface of the charging device 1, and a power switch PW and a charging start switch ST are disposed.

  The plurality of connectors for connecting the electronic devices provided in the charging device 1 are configured by, for example, USB (Universal Serial Bus) terminals, and the electronic devices 2 can be connected via the cable 5 in a one-to-one relationship. It has become. Here, a plurality of connectors (4 ports in this embodiment) are provided for connecting electronic devices, and a maximum of four electronic devices 2 can be connected as charging targets. The electronic device 2 is a mobile phone that uses a secondary battery (for example, a lithium battery) as a power source. When the electronic device (mobile phone) 2 is connected to the charging device 1, the electronic device 2 is electronically supplied with power from the charging device 1. The device 2 is charged. Here, the management device 3 is charged by performing short-range wireless communication (non-contact type communication such as non-contact IC card, Bluetooth (registered trademark), infrared communication) with the electronic device 2, for example. By collecting and receiving information on the usage status from each electronic device 2 connected to the device 1, it is collected and stored and managed.

  That is, the above-described information on the usage status of the electronic device 2 (hereinafter referred to as usage status) includes past usage status (for example, user behavior history) and future usage status (for example, user behavior schedule). Each electronic device 2 transmits this usage status to the charging device 1 via the cable 5 in response to a transmission request from the charging device 1, or in response to a transmission request from the management device 3 as described above. Then, the data is transmitted to the management apparatus 3 side via short-range wireless communication. The management device 3 collects and manages the usage status received and acquired from each electronic device 2 for each electronic device 2, and electronically connects the charging device 1 via the cable 4 in response to a transmission request from the charging device 1. The usage status for each device 2 is transmitted.

FIG. 2 is a block diagram illustrating basic components of the charging device 1 and the electronic device 2. The charging device 1 has a charging control unit 11 as a core, and the charging control unit 11 includes various types of information stored in the storage unit 12. The whole operation of the charging device 1 is controlled according to the program, and has a central processing unit, a memory (not shown), and the like. The storage unit 12 is an internal memory such as a ROM or a RAM, and has a program area and a data area. In this program area, a program for realizing the present embodiment in accordance with an operation procedure shown in FIG. Is stored. In addition, in the data area of the storage unit 12, various information necessary for the operation of the charging device 1 is temporarily stored in addition to flag information (a setting flag described later), timer information (a charging timer described later), and the like. .

  The charging circuit unit 13 charges the electronic device 2 in a state in which it is detected that the electronic device 2 is connected. The output current (rated) is, for example, 2000 mA, and the connection of the electronic device 2 is performed. In the case where the number is one, charging (single charging) for supplying output current to the one electronic device 2 is performed once, but a plurality of units (2 to 4 units) are provided. In this case, it is assumed that charging is performed in predetermined times (in this embodiment, twice). That is, for example, if the number of connected electronic devices 2 is two, single charging is performed twice for each unit, and if three units are used, only one single charging is performed at the first time, Charge 2 units at the same time for the second time, and if the number of connected units is 4, charge at the same time for 2 units at the first time, and charge the remaining 2 units at the second time. ing.

  Here, when charging two electronic devices 2 at the same time, the output current of the charging device 1 is equally divided into charging currents of 1/2 (1000 mA) and supplied to each electronic device 2. become. In this embodiment, when the number of connected electronic devices 2 is three, only one unit is single-charged at the first time and two units are simultaneously charged at the second time. On the contrary, two units may be charged simultaneously at the first time and only one unit may be charged at the second time. In this embodiment, when charging is performed in a predetermined number of times, the predetermined number of times is two. However, the number of times is not limited to this, and may be three or more. For example, when the number of connected electronic devices 2 is 4, only one unit is charged at the first time, two units are charged at the same time at the second time, and only one unit is charged at the third time. May be performed. In this embodiment, up to four electronic devices 2 can be connected. However, the number may be five or more. For example, when the number of electronic devices 2 is five, the first time. It is also possible to perform single charging for only one unit, perform simultaneous charging for two units at the second time, and perform simultaneous charging for the remaining two units at the third time.

  In this way, when a plurality of (two to four) electronic devices 2 are connected, the charging circuit unit 13 charges the plurality of electronic devices 2 at a predetermined time under the control of the charging control unit 11. Although the process is performed separately, which electronic device 2 is charged at what time is controlled in consideration of the use status of the electronic device 2 described above. That is, the charging control unit 11 predicts information on the future use date and time for each electronic device 2 based on the use situation acquired corresponding to each of the plurality of electronic devices 2, and relates to the future use date and time. The priority order of charging is determined based on the information, and based on this priority order, which electronic device 2 is charged at what time is controlled. Note that the charging circuit unit 13 performs on / off control of power supply to each connector for connecting an electronic device in order to realize the above-described charging control, or controls switching between single charging / simultaneous charging. A circuit is provided.

  In this case, information on future use date and time (hereinafter referred to as use date and time) means that the electronic device 2 is scheduled to be used, such as the scheduled date and time of going out (scheduled date and time of going to work or school), the date and time of the event Date and time. In this embodiment, the date and time is not limited to the hour and minute and date, but may be only the hour and minute, only the day of the week, or only the date (the same applies hereinafter). The charging control unit 11 determines the priority of charging so that charging is started earlier as the usage date and time is closer to the current date and time (date and time when the charging start switch ST is operated), and this priority is higher. The (early) electronic device 2 is charged at the first time, and the electronic device 2 with a low priority (slow) is charged at the second time. For example, when the number of connected electronic devices 2 is 3, single charging is performed for the electronic device 2 having the highest priority at the first time, and the remaining two electronic devices 2 are performed at the second time. I try to charge at the same time. When the number of connected electronic devices 2 is four, the electronic device 2 with the highest priority at the first time and the electronic device 2 with the second highest priority are simultaneously charged, and the remaining two at the second time. Are charged at the same time.

  The electronic device connection unit 14 includes the plurality of connectors (USB terminals) described above, and the charge control unit 11 is connected to the electronic device 2 based on a signal indicating a connection state from the electronic device connection unit 14. Whether the electronic device 2 is connected to which connector is detected, how many are currently connected, and the electronic device according to the detection result 2 is controlled. In addition, the charging control unit 11 can transmit and receive information (usage status) to and from the electronic device 2 through the electronic device connection unit 14 in a state where the electronic device 2 is connected.

  The management device connection unit 15 has a connector (USB terminal) to which the management device 3 is connected, and the charge control unit 11 is connected to the management device 3 based on a signal indicating a connection state from the management device connection unit 15. If the management apparatus 3 is connected, information (usage status of each electronic device 2) is transmitted to and received from the management apparatus 3 via the management apparatus connection unit 15. I am doing so. FIG. 3A shows whether the charging control unit 11 receives and acquires information (usage status) from each electronic device 2 or receives information (usage status of each electronic device 2) from the management device 3. It is determined by referring to the usage status acquisition destination information.

  The usage status acquisition destination information shown in FIG. 3 (1) indicates a guideline from where the usage status is received and acquired, and is arbitrarily set by a user operation. It has the structure which has. “Acquisition destination” indicates from where the usage status is received and acquired, and may be acquired “from each electronic device 2” or “from the management device 3”. The “setting flag” indicates which acquisition source is valid. When the value is “1”, it is valid, and when it is “0”, it is invalid. In the illustrated example, “from each electronic device 2” is valid.

  The time measuring unit 16 measures information on the current date and time, and the charging control unit 11 refers to the current date and time when determining the priority order of charging described above. The display unit 17 has the above-described display screen DP and uses a high-definition liquid crystal or an organic EL. The display unit 17 notifies whether or not charging is in progress by a message display or the like. I will inform you. In this case, the notification of the priority order is performed by displaying information indicating the number of times of charging corresponding to each of the connected electronic devices 2. The operation unit 18 includes the power switch PW and the charge start switch ST described above, and the charge control unit 11 performs processing according to an operation signal from the operation unit 18.

The storage unit 23 is an internal memory such as a ROM or a RAM, and has a program area and a data area, and various programs are stored in the program area.

  The data area of the storage unit 23 temporarily stores various types of information necessary for the operation of the electronic device 2 and also stores a device identifier (device ID) for identifying the electronic device 2. In addition to M1, it has a usage history storage unit M2 and a usage schedule storage unit M3, which will be described later. The battery unit 22 includes a secondary battery 22 a that is charged by supplying power from the charging device 1 in a state where the battery unit 22 is cable-connected to the charging device 1. The charging connection unit 24 has a connector (USB terminal) and is connected to the electronic device connection unit 14 on the charging device 1 side, and can transmit and receive information to and from the charging device 1.

  The wireless communication unit 25 transmits / receives data to / from the nearest base station (not shown). During operation of the call function, the wireless communication unit 25 takes in a signal from the receiving side of the baseband unit and demodulates it into a received baseband signal. When output to the central control unit 21, the central control unit 21 outputs audio from the call speaker SP via the audio signal processing unit 26, and input audio data from the call microphone MC is output to the audio signal processing unit 26. And is encoded into a transmission baseband signal, which is then given to the transmission side of the baseband part and transmitted from the antenna AN1. The display unit 27 uses high-definition liquid crystal or organic EL and displays, for example, standby data, icons, date / time information, text data, and the like.

  The operation unit 28 inputs a power on / off key, dial input, character input, command input, and the like, and the central control unit 21 executes processing according to an input operation signal from the operation unit 28. The short-range wireless communication unit 29 transmits and receives data to and from the management device 3 by short-range wireless communication. For example, a non-contact type communication such as a non-contact IC card, Bluetooth (registered trademark), or infrared communication. Means. The television broadcast receiving unit 30 receives a one-segment terrestrial digital television broadcast for a communication terminal device via an antenna AN2.

FIG. 4A is a diagram for explaining the usage history storage unit M2.
The usage history storage unit M2 stores, for example, a user's behavior history as a past usage situation, and includes “ID”, “date / time”, and “item”. In the illustrated example, the usage history storage unit M2 constitutes a diary that stores and manages the sales history of the salesperson (1) in the company as a usage history, and the departure date and time from the customer A and from the customer A Memorize the date and time of return. “ID” is a serial number (identifier) that identifies a usage history. “Date and time” indicates the date and time of action, and “Item” indicates the specific content of the action. Further, in the example shown in the figure, it is shown that the salesperson (1) went to work at 08:48 am and departed for customer A at 10:12 am.

FIG. 4B is a diagram for explaining the use schedule storage unit M3.
The use schedule storage unit M3 stores, for example, a user's action schedule as a future use situation, and has “ID”, “date and time”, and “item”. The user's action schedule stores, for example, a scheduled wake-up date, a scheduled attendance date / time, and the like as a scheduled date / time and schedule content, and “ID” is a serial number (identifier) that identifies a usage schedule. “Date and time” indicates the scheduled date and time for action, and “Item” indicates the specific content of the action schedule. In the illustrated example, it is shown that the father got up at 07:00 am and went to work at 08:00 am.

  The contents of the usage history storage unit M2 and the usage schedule storage unit M3 are directly transmitted from each electronic device 2 to the charging device 1 as the usage status of the electronic device 2, or transmitted to the charging device 1 via the management device 3. Is done. That is, the charging device 1 determines whether to acquire directly from each electronic device 2 or via the management device 3 based on the contents of the usage status acquisition destination information shown in FIG. Based on the usage status of each electronic device 2, information on the future usage date and time is predicted for each electronic device 2, and charging priority is determined based on the information on the future usage date and time. At this time, in this embodiment, the priority of charging is determined with reference to either the usage history or the usage schedule as the usage status. In this case, whether to determine the priority order of charging with reference to either the use history or the use schedule is determined based on the priority order decision guideline information shown in FIG.

  The priority order determination guideline information in FIG. 3 (2) is a guideline for instructing what kind of usage status is to be used as the usage status to determine the priority order of charging. It is set and has a “setting flag” corresponding to the “guideline”. “Guideline” designates either “usage history” or “scheduled usage” as the type of usage status. The “setting flag” indicates which guideline is valid. When the value is “1”, it is valid, and when it is “0”, it is invalid. The illustrated example shows a case where it is set that priority should be determined based on “usage history”.

  Next, the operation concept of the mobile phone 1 in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. The same applies to other embodiments described later. In addition to the recording medium, an operation peculiar to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 5 is a flowchart showing an outline of the overall operation of the charging apparatus 1.
First, on the charging device 1 side, when the power-on operation is performed by the power switch PW (YES in Step A1), the charging control unit 11 detects which electronic device 2 is connected (Step A2). ), The process waits until the electronic device 2 is connected. However, when at least one electronic device 2 is connected (YES in step A2), the operation waits for the charging start switch ST (step A3). In addition, in this flowchart, when all the charging to the electronic device 2 is completed, or not illustrated, this flow is finished when a power-off operation is performed by the power switch PW. Even when it is detected that no electronic device 2 is connected, this flow may be terminated, and the termination method is arbitrary.

  When the charging start switch ST is operated to start charging (YES in step A3), the charging control unit 11 accesses the electronic device connection unit 14 to connect the connected electronic device 2. In addition to measuring the number of units (step A4), a request for transmission of a device ID is made to each connected electronic device 2, and in response to this, it is read from the device ID storage unit M1 on the electronic device 2 side and transmitted. The received device ID is received for each electronic device 2 (step A5). Then, it is checked whether the number of connected electronic devices 2 is plural (step A6). If not plural, that is, if only one is connected (NO in step A6), this one Single charging for supplying the output current (2000 mA) of the charging device 1 to the electronic device 2 is started (step A7). Then, it is checked whether the charge timer has timed out (timer expired) (step A18), and this single charge is continued until the charge timer expires (YES in step A18) (step A7).

  Here, the charging timer measures the charging time from the start of charging to the end of charging, and a timer time arbitrarily set in advance by a user operation (for example, 60 minutes for single charging) has elapsed. Continue charging until As the timer time, the time required until the battery is fully charged from the state where the remaining battery level is zero is set as standard. However, for example, an arbitrary time such as 2/3 hours required for the full charge is set. You may make it set time. Here, when the timer end is detected (YES in Step A18), after charging is finished (Step A19), it is checked whether there is any other electronic device 2 that has not been charged (Step A20). This is a case where the number of connected electronic devices 2 is one and the single charging is completed, and no other electronic devices 2 that have not been charged remain (YES in step A20). Return to.

If the number of connected electronic devices 2 is plural (2 to 4) (YES in step A6), the usage status acquisition destination information shown in FIG. It is checked whether the “acquisition destination” of “1” is “from each electronic device 2” (step A8). Here, if the “acquisition destination” is “from each electronic device 2” (YES in step A8), the charging apparatus 1 sends a usage status transmission request to each connected electronic device 2, In response, the contents read from the usage history storage unit M2 or the usage schedule storage unit M3 are received and acquired as usage status from each electronic device 2 (step A9).
Subsequently, referring to the priority order determination guideline information in FIG. 3B, the process proceeds to step A11 for acquiring either the use history or the use schedule.

If the “acquisition destination” is “from the management apparatus 3” (NO in step A8), a request for transmission of the usage status is sent to the management apparatus 3 side, and the response is transmitted from the management apparatus 3 side in response thereto. The usage status of each electronic device 2 is received and acquired (step A10). That is, on the management device 3 side, the contents of the usage history storage unit M2 or the usage schedule storage unit M3 of each electronic device 2 are stored and managed, and the charging device 1 stores the device ID of each electronic device 2 connected thereto. By transmitting to the management device 3 side, a request for transmission of the usage status of the electronic device 2 is made, and in response thereto, the usage status corresponding to the device ID transmitted from the management device 3 is obtained.
Subsequently, referring to the priority order determination guideline information in FIG. 3B, the process proceeds to step A11 for acquiring either the use history or the use schedule.

  In step A11, the priority determination guideline information in FIG. 3 (2) is referred to, and it is checked whether the “setpoint” with “1” is “use history”. If there is (YES in step A11), a future use date (planned date to go out) is determined (predicted) based on the “use history” of each electronic device 2 (step A12). FIG. 4 (3) shows the usage history information for each user managed and stored by receiving (collecting) the contents of the usage history storage unit M 2 as the usage status from each electronic device 2 on the management device 3 side. FIG. This user-specific usage history information includes “ID”, “user”, “date / time”, and “item”. “ID” indicates an identifier for identifying a user (salesperson), and “user” Indicates the user name (salesperson name) of the electronic device 2.

  For example, as shown in FIG. 4 (3), the departure time of the salesperson (1) is “10:12”, the departure time of the salesperson (2) is “09:45”, and the salesperson (3) If the departure time is “11:00”, salespersons (1) to (3) based on the past use date “10:12”, “09:45”, “11:00” Determine (predict) the use date and time (scheduled date and time) for the future (for example, tomorrow). In this case, not only the use history of the previous day but also, for example, referring to the use history for one week, one month, and several months, the future use date and time (planned date and time to go out) is determined (predicted). Also good. Also, what day of the week and what time may be predicted as the future use date and time (scheduled date and time to go out).

  If the “setting flag” is “1” and the “guideline” is “scheduled for use” (NO in step A11) as a result of referring to the priority order determination guideline information in FIG. A future use date / time (planned date / time to go out) is determined (predicted) based on the “use schedule” (step A13). FIG. 4 (4) shows information on the usage schedule for each user that is received and collected (collected) as the usage status from each electronic device 2 on the management device 3 side and stored and managed. It is a figure. This user-specific use schedule information includes “ID”, “user”, “date / time”, and “item”, and “ID” is information for identifying a user (a family member such as a father or mother). “User” indicates a user name (name of father, mother, etc.).

  For example, as shown in FIG. 4 (4), the scheduled attendance time of the father is “08:00”, the scheduled attendance time of the mother is “09:00”, and the scheduled attendance time of the child (university student) is “10 o'clock”. If it is “00 minutes”, the scheduled date and time for going out of the father, mother, and child are determined (predicted) based on the future use dates “08:00”, “09:00”, and “10:00”. . In this case, not only the schedule information for today, but for example, referring to the schedule information for one week, one month, and several months ahead, determine (predict) the future use date and time (scheduled date and time) It may be.

  Further, the future use date / time (scheduled date / time to go out) predicted for each electronic device 2 as described above is compared (step A14), and the priority of charging is determined based on the comparison result (step A15). In this case, the priority of charging is determined so that the charging is started earlier as the future use date and time (planned date and time of going out) is closer to the current date and time (operation date and time of the charging start switch ST). For example, in the case of FIG. 4 (3), if the current date and time is “November 20, 09:00”, the order of salespersons (2), (1), (3) is set as the priority of charging. In the case of FIG. 4 (4), if the current date and time is “November 20, 06:00”, the order of charge, father, mother, and child is determined.

  When the priority order of charging is determined in this manner, the priority order is displayed on the display unit 17 to notify the user (step A16), and then charging is started based on the priority order (step A17). At that time, charging of the plurality of electronic devices 2 is performed in predetermined times (twice). That is, as described above, if the number of connected electronic devices 2 is two, single charging is performed twice for each unit, and if three units are used, only one unit is charged for the first time. In the second time, two units are charged simultaneously. If four units are used, two units are simultaneously charged in the first time, and the remaining two units are simultaneously charged in the second time. In this case, as to which electronic device 2 is charged at what time, the higher the priority is, the faster the charging starts. For example, in the specific example shown in FIG. 4 (3), when the electronic devices 2 of the salespersons (1), (2), and (3) are connected, the electronic device of the salesperson (2) at the first time. Start a single charge of only 2. Similarly, in the specific example shown in FIG. 4 (4), when the father, mother, and child electronic devices 2 are connected, single charging of only the father's electronic device 2 is started at the first time.

  Then, it is checked whether the charge timer has timed out (timer expired) (step A18), and charging is continued until the timer expires. In this case, charging is continued until a timer time arbitrarily set in advance by a user operation (for example, 120 minutes for simultaneous charging) elapses. Thereafter, when the end of the timer is detected (YES in step A18), the charging is terminated (step A19), and then it is checked whether there are any other electronic devices 2 that are not charged (step A20). Here, in the above-described example, when only one unit of the single charge is completed and the other electronic device 2 remains (NO in step A20), the process returns to the above-described step A17, and the charge priority order Based on the above, the second charging is started, but if there is no other electronic device 2 that has not been charged (YES in step A20), the process returns to step A2 described above.

  Now, for example, in the case of FIG. 4 (3), the process returns to the above-described step A17 to start the simultaneous charging of the sales staff (1) and (3) to the electronic device 2 for the second time. In the case of FIG. 4 (4), simultaneous charging of the mother and child electronic devices 2 is started at the second time. In such simultaneous charging for two devices, the output current of the charging device 1 is equally divided into halves for charging. Then, after starting the second charge, the process proceeds to step A18 described above, and the second charge is continued until the timer ends. Thereafter, when the end of the timer is detected (YES in step A18), in the above example, since there is no other electronic device 2 that is not charged (YES in step A19), the process returns to the above step A2 at this time. .

  As described above, in the first embodiment, the charging device 1 determines the priority of charging based on the usage status of the plurality of electronic devices 2, and controls charging based on this priority. In a state where a plurality of electronic devices 2 are connected as charging targets, it is possible to realize appropriate charging in consideration of individual usage status of each electronic device 2. For example, it is possible to preferentially charge the electronic device 2 of the user who is going to go out early, and it is possible to prevent the battery from running out when going out. Furthermore, since information such as the remaining battery level is not required from the electronic device 2, it is not necessary to provide a complicated circuit on the charging device 1 side or the electronic device 2 side. .

  In addition, the charging device 1 predicts the future use date and time for each electronic device 2 based on the use status of the plurality of electronic devices 2, and determines the charging priority order based on the future use date and time. For example, when determining the priority order of charging, the priority order can be appropriately determined based on the date and time.

  If the charging device 1 acquires the usage status from each of the plurality of connected electronic devices 2, the current usage status can be obtained directly from the electronic device 2 even if the usage status changes frequently. And more appropriate charge control is possible.

  If the charging device 1 acquires the usage status of each electronic device 2 from the management device 3, the usage status of each electronic device 2 can be collectively acquired by accessing the management device 3. Can be reduced.

  If the charging device 1 acquires the usage history as the usage status of each electronic device 2, it can accurately predict the future usage date and time. For example, by referring to the usage history for one week, one month, and several months, it is possible to predict future usage dates and times (more accurate prediction of going-out dates and times).

  The charging device 1 can accurately predict the future use date and time by acquiring schedule information as the use status of each electronic device 2 and predicting the future use date and time. For example, by referring to schedule information for one week, one month, and several months ahead, it is possible to more accurately predict future use dates (planned dates for going out).

  The current date and the future use date and time are compared, and the charge priority is higher as the current date and time are closer to the future use date and time, so that the charge can be prioritized as the use is earlier.

  If the charging apparatus 1 arbitrarily sets priority order determination guideline information for instructing what kind of usage situation to determine the priority order of charging as a usage situation by a user operation, The priority order can be determined based on the usage situation intended by the user.

  If the charging device 1 displays (notifies) the priority order of charging, the user can know how much his / her electronic device 2 is charged.

  The charging device 1 performs charging in predetermined times according to the number of connected electronic devices 2, and controls which electronic device 2 is charged at what time based on the priority of charging. As a result, it is possible to achieve efficient charging as a whole rather than sequentially charging each electronic device 2 one by one.

In the first embodiment described above, the user's behavior history is used as the past usage status (usage history). However, it may be a call outgoing / incoming history, based on this outgoing / incoming history. Thus, the order of charge may be determined by analyzing how to use the telephone.
In the above-described first embodiment, the user's action schedule is used as the future usage status (usage schedule), but it may be a wake-up setting date and time.

  In the first embodiment described above, information on future use date and time is predicted with reference to either the use history or the use schedule. However, with reference to both the use history and the use schedule, Information regarding future use date and time may be predicted.

  In the first embodiment described above, the management device 3 receives and acquires the usage status from each electronic device 2 via short-range wireless communication. However, the usage status of each electronic device 2 is communicated via the Internet. In the case where storage management is performed in the server device (not shown) on the side, the usage status of each electronic device 2 may be received and acquired from this server device. Of course, it may be obtained directly from the server device without going through the management device 3, and the acquisition method is arbitrary.

  In the first embodiment described above, the charging device 1 determines the priority of charging from the usage status of each electronic device 2 every time the charging start switch ST is operated. However, the usage status does not vary greatly. In this case, the priority order may be determined periodically every predetermined period, for example, once a week or once a month.

(Second Embodiment)
A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, the priority order of charging is determined based on the usage status of each electronic device 2. In the second embodiment, however, the charging priority is determined based on the charging history of each electronic device 2. Thus, the priority of charging is determined. In addition, in the first embodiment described above, the management apparatus 3 is used. However, in the second embodiment, the case where the management apparatus 3 is not used is illustrated.
Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 6A is a diagram for explaining a charge history storage unit M4 (not shown in FIG. 2) provided in the storage unit 23 of the electronic device 2 in the second embodiment.
The charging history storage unit M4 stores information (charging history) at the time of charging, and has items of “ID”, “user”, and “charging history”. The “charging history” It has items of “start”, “end”, “disconnect”, and “frequency”. “ID” indicates a serial number (identifier) for identifying a charging history, and “user” indicates a user name of the electronic device 2 or the like. The “charging history” indicates information (charging history) at the time of charging. “Start” indicates the charging start date and time, “End” indicates the charging end date and time, and “ “Release connection” indicates the date and time when the connection to the charging device 1 is disconnected (released) by lifting the electronic device 2 from the charging device 1, and “Frequency” is the number of times of charging per week, The frequency one week ago is shown.

  FIG. 6 (2) is a diagram showing charging history information for each user who receives and collects (collects) the contents of the charging history storage unit M4 from each electronic device 2 and stores and manages them on the charging device 1 side. It is. The charging history information for each user includes “ID”, “user”, and “charging history”. The “charging history” further includes “start”, “end”, “disconnection”, and “frequency”. Have items. “ID” indicates an identifier for identifying a user (a family member such as father or mother), and “user” indicates a user name (for example, a name such as father or mother).

  FIG. 7A is a diagram showing the charging history acquisition destination information in the second embodiment. This charging history acquisition destination information indicates a guideline from which the charging history is received and acquired, and is arbitrarily set by a user operation. The “configuration flag” corresponding to the “acquisition destination” is configured. “Acquisition destination” indicates from where the charging history is received and acquired, and may be acquired “from each electronic device 2” or “from charging device 1 (self)”. In the first embodiment described above, the information (usage status) of each electronic device 2 is collected by the management device 3 and stored and managed. However, the charging device 1 in the second embodiment is not limited to each electronic device 2. The contents of the charge history storage unit M4 are collected from the device 2 and stored and managed. The “setting flag” indicates which acquisition source is valid and is valid when the value is “1” and invalid when the value is “0”. In the example shown in the figure, a state set when acquiring “from each electronic device 2” is shown.

FIG. 7B is a diagram showing priority order determination guideline information in the second embodiment.
This priority determination guideline determines which charge history should be referred to from among charge end date / time, connection release date / time, and charge frequency when determining the charge priority based on the charge history. This is a pointer that is arbitrarily set by a user operation, and has a “setting flag” corresponding to the “pointer”. “Guideline” indicates which one of charging end date / time, connection release date / time, and charging frequency is referred to, and includes “charge end date / time”, “charge frequency”, and “connection release date / time”. The “setting flag” indicates which guideline is valid. When the value is “1”, it is valid, and when it is “0”, it is invalid. The illustrated example is a case where it is set to determine the priority order “from the charging end date and time”.

8 and 9 are flowcharts showing an outline of the overall operation of the charging device 1 in the second embodiment.
First, on the charging device 1 side, when the power-on operation is performed (YES in step B1 in FIG. 8), the charging control unit 11 performs any one of the electronic devices as in steps A1 to A5 in FIG. 2 is detected (step B2), and it waits until the electronic device 2 is connected, but when even one electronic device 2 is connected (YES in step B2), the charging start switch ST (Step B3).

  Now, when the charging start switch ST is operated to start charging (YES in step B3), the number of connected electronic devices 2 is measured (step B4), and each connected electronic device 2 is measured. The device ID is requested to be transmitted, and in response to this, the device ID read and transmitted from the device ID storage unit M1 on the electronic device 2 side is received and acquired (step B5). And the charge control part 11 searches the information of the charge history classified by user of FIG. 6 (2) based on this apparatus ID, transmits the charge history of a corresponding user to the electronic device 2, and stores the charge history By rewriting the contents of the part M4, the charging history on the electronic device 2 side and the charging history on the charging device 1 side are matched (step B6). This matching process (step B6) may be performed after the charging history is updated on the charging device 1 side, for example, after step B29 described later, but in the second embodiment, before the charging history is updated. The matching process (step B6) is performed.

  Then, the charging control unit 11 checks whether there are a plurality of electronic devices 2 connected (step B7). When only one electronic device 2 is connected (NO in step B7), this one electronic device 2 is connected. Single charging is started for the device 2 (step B8). Subsequently, it is checked whether the charge timer has timed out (timer expired), and the process proceeds to step B23 in FIG. 9 where the single charge is continued until the timer expires. Here, when the end of the timer is detected (YES in step B23), after charging is terminated (step B24), the information on the charging history for each user in FIG. The current date and time are additionally recorded as the charging end date and time in the “end” of the corresponding “charging history” (step B25), and the “frequency” is updated and recorded (step B26).

  Then, it is checked whether or not the connection of the electronic device 2 is disconnected (step B27). When the connection is released (YES in step B27), the information on the charging history for each user in FIG. Then, the current date and time are additionally recorded as “connection release date and time” in “connection release” of the “charging history” corresponding to the electronic device 2 whose connection has been released (step B28). Then, it is checked whether there is any other electronic device 2 that has not been charged (step B29). Now, since the number of connected electronic devices 2 is one and the single charging is completed ( In step B29, YES), the process returns to step B2 described above.

  If the number of connected electronic devices 2 is plural (2 to 4) (YES in step B7 in FIG. 8), the charging history acquisition destination information shown in FIG. It is checked whether the “acquisition destination” with the setting flag “1” is “from each electronic device 2” (step B9). Here, if the “acquisition destination” is “from each electronic device 2” (YES in step B9), the charging device 1 makes a transmission request for charging history to each connected electronic device 2, In response, the content of the charge history storage unit M4 transmitted from each electronic device 2 is received and acquired (step B10). In this case, the charging apparatus 1 refers to the priority determination guide information in FIG. 7B and acquires any one of “charging end date / time”, “connection release date / time”, and “charging frequency”.

  If the “acquisition destination” is “from the charging device” (NO in step B9), the charging device 1 is connected in a state where the contents of the charging history storage unit M4 of each electronic device 2 are stored and managed. The charging history corresponding to the device ID of each electronic device 2 being read is read out and acquired (step B11). Even in this case, the charging apparatus 1 reads out and acquires one of “charging end date / time”, “connection release date / time”, and “charging frequency” with reference to the priority determination guide information in FIG. To do.

  Then, referring to the priority order determination guideline information in FIG. 7B, the “guideline” with the “setting flag” being “1” is “charging end date” (step B12) or “charging frequency”. Or “connection release date / time” (step B13). If the “guideline” with the “setting flag” being “1” is “charging end date / time” (YES in step B12), the electronic device 2 is referred to by referring to the charging history information for each user in FIG. Every time (for each user), the previous charging end date and time are read from “End” of “Charging History”, compared (Step B14), and the priority of charging is determined based on the comparison result (Step B15). ). In this case, a priority order is determined such that the older the charging end date and time, the higher the order. In the specific example of FIG. 6 (2), when the current date and time is “November 20, 2009, 23:00”, the charging end date and time is “Act 20:20, November 20, 2009” by user A. Since user B is “November 20, 2009, 10:00”, user B is older, so the priority order is user B> user A.

  Also, as a result of referring to the priority order determination guideline information in FIG. 7B, if the “setpoint” is “1” and the “guideline” is “charge frequency” (YES in step B13), “charge history” The charging frequency is read out from “Frequency”, and compared (step B16), and the priority of charging is determined based on the comparison result (step B17). In this case, the priority order is determined such that the higher the charging frequency, the higher the order. In the specific example of FIG. 6 (2), the charging frequency of the user A is “5 times / previous week” and the charging frequency of the user B is “2 times / previous week”. , User A> user B.

Further, as a result of referring to the priority order determination guideline information in FIG. 7B, if the “setpoint” is “1” and the “guideline” is “connection release date / time” (NO in step B13), “charge history” The previous connection release date and time are read out from “connection release” of “”, compared with each other (step B18), and the charge priority order is determined based on the comparison result (step B19). In this case, the priority order is determined such that the higher the order is, the farther the date and time when the connection with the charging apparatus 1 is disconnected is from the current date and time. In other words, the order of priority for charging is determined so that the one that is cut first has a higher priority. In the specific example of FIG. 6 (2), when the current date and time is “November 20, 2009, 07:00”, the connection release date and time is “November 20, 2009, 10:30” Since the user B is “November 19, 2009, 11:20”, the user B is farther away (because the connection is disconnected first), so the priority order is user B> user A.

  When the priority order of charging is determined in this way, the priority order is displayed on the display unit 17 to notify the user (step B20 in FIG. 9), and then charging is started based on the priority order (step B21). ). At that time, as in the first embodiment described above, the charging of the plurality of electronic devices 2 is performed in predetermined times (two times), and which electronic device 2 is charged at what number of times has priority. The higher the value, the faster charging starts. When charging is started in this way, the information on the charging history for each user in FIG. 6 (2) is referred to, and the current date and time is displayed in “Start” of “Charging history” corresponding to the electronic device 2 that has started charging. Additional recording is performed as the charging start date and time (step B22).

  Then, it is checked whether the charge timer has timed out (timer expired) (step B23), and charging is continued until the timer expires. Thereafter, when the end of the timer is detected (YES in step B23), after the charging is terminated (step B24), the current date and time are set as the end date of charging in the “end” of the “charging history” in the same manner as described above. While additionally recording (step B25), the "frequency" is updated (step B26). When the connection of the electronic device 2 is cut and the connection is released (YES in step B27), the current date and time are additionally recorded as the connection release date and time in “connection release” of “charging history” (step B28). Then, it is checked whether there is any other electronic device 2 that has not been charged (step B29). If another electronic device 2 remains (NO in step B29), the process returns to the above-described step B21 to charge the battery. Based on the priority order, the second charging is started. If no other electronic device 2 remains (YES in step B29), the process returns to step B2 described above.

  As described above, in the second embodiment, the charging device 1 determines the priority of charging based on the charging history of the plurality of electronic devices 2, and controls charging based on this priority. In a state where a plurality of electronic devices 2 are connected as charging targets, it is possible to realize appropriate charging in consideration of individual charging histories of each electronic device 2, and information such as the remaining battery level can be obtained from the electronic device 2. Since it is not necessary, it is not necessary to provide a complicated circuit or the like on the charging device 1 side or the electronic device 2 side, so that the practical effect in accordance with the actual situation is high.

  If the charging device 1 acquires the charging history from each of the plurality of connected electronic devices 2, the charging device 1 can directly acquire the current charging history from the electronic device 2 even if the charging history fluctuates frequently. And appropriate charge control becomes possible.

  If the charging device 1 reads out the charging history corresponding to the device ID of each connected electronic device 2 in a state where the charging history of each electronic device 2 is stored and managed, the charging device 1 acquires the charging history. The burden on each electronic device 2 side can be suppressed, and even in the electronic device 2 that does not have the function of recording the charging history, the charging priority order can be determined based on the charging history on the charging device 1 side.

  If the charging device 1 determines the priority of charging so that the higher the order of the previous charging date and time, the higher the order of charging, the standard battery remaining amount (power consumption amount) depending on the elapsed time since charging. ) Can be predicted, and the priority of charging can be determined according to the prediction.

  The charging device 1 is expected to have a large power consumption (battery consumption) if the charging priority is determined so that the higher the charging frequency is, the higher the ranking is. The charging priority can be determined according to the prediction.

  If the charging device 1 determines the priority of charging so that the rank becomes higher as the connection release date and time is farther from the current date and time, the fact that the connection release is faster means that the power consumption (battery consumption amount) is larger. The charging priority can be determined according to the prediction.

  If the charging apparatus 1 can arbitrarily set the priority determination guide information that indicates what kind of charging history is referred to determine the charging priority as the charging history by the user operation, The priority order can be determined based on the charging history intended by the user.

  If the charging device 1 displays (notifies) the priority order of charging, the user can know how much his / her electronic device 2 is charged.

  The charging device 1 performs charging in predetermined times according to the number of connected electronic devices 2, and controls which electronic device 2 is charged at what time based on the priority of charging. As a result, it is possible to achieve efficient charging as a whole rather than sequentially charging each electronic device 2 one by one.

In each of the above-described embodiments, the wired connection type charging device 1 that connects the charging device 1 and each electronic device 2 via the cable 5 is exemplified, but a non-contact charging method (for example, an electromagnetic induction method). You may make it apply to the non-contact-type charging device which employ | adopted.
FIG. 10 is an external view showing a non-contact type charging device 1, and the charging device 1 has an entire casing that forms a box, and an upper surface of the charging device 1 on which an electronic device 2 is mounted. It has become. A plurality of (four) charging primary coils 1b arranged in a matrix of rows (vertical) 2 × columns (horizontal) 2 on the entire mounting surface 1a of the non-contact type charging device 1. Is buried. That is, the mounting surface 1a of the charging device 1 is divided into four equal parts by two imaginary lines (vertical and horizontal partition lines) passing through the center point, and a charging primary coil 1b is provided in each of the four equal parts. Each one is buried. The electronic devices 2 are placed one by one in accordance with each of the divided areas. Accordingly, a configuration is possible in which up to four electronic devices 2 can be placed simultaneously.

  In this case, the electronic device 2 is provided with a secondary coil for charging (not shown) in addition to the secondary battery, and the electronic device 2 is mounted (connected) on the mounting surface 1 a of the charging device 1. In this state, charging with the non-contact type charging device 1 is performed by an electromagnetic induction method. Here, contact sensors (not shown) for detecting that the electronic device 2 is placed are arranged at the arrangement positions of the respective charging primary coils 1b, and based on the detection results of these contact sensors. It is detected whether or not how many electronic devices 2 are placed, and at which position the electronic devices 2 are placed. And it supplies with respect to the primary coil 1b for charge matched with the position in which the electronic device 2 is mounted, but in that case, like each embodiment mentioned above, it connects to the number of connection of the electronic device 2. Power is supplied according to the requirements.

  Even in this case, it is checked whether there are a plurality of electronic devices 2 connected. If only one electronic device 2 is connected, an output current of 2000 mA is supplied to the single electronic device 2. Start single charging, if the number of connected electronic devices 2 is two, divide each unit into two single charges, and if three, only one single charge at the first time In the second time, two units are charged simultaneously. If four units are used, two units are simultaneously charged in the first time, and the remaining two units are simultaneously charged in the second time. In this case, as to which electronic device 2 is charged at what time, the higher the priority is, the faster the charging starts.

  Even when applied to the non-contact type charging device 1 as described above, the same effect as that of the wired connection type charging device 1 is obtained, and the convenience of connecting the electronic device 2 to the connector is reduced and the convenience is improved. Is possible.

  The charging device 1 is not limited to the electromagnetic induction method as the contactless charging method, and may be a radio wave receiving method or a resonance method using an electric field or a magnetic field. Here, the contact device is disposed on the connection surface (mounting surface) between the charging device 1 and the electronic device 2 to detect that the charging device 1 is mounted on the electronic device 2. For example, you may make it detect using an electromagnetic induction effect | action. In this case, what is necessary is just to detect that the electronic device 2 was mounted in the charging device 1 by whether the electromotive force generated by the electromagnetic induction action was larger than a predetermined value.

  Further, in each of the above-described embodiments, the charging device 1 performs charging in predetermined times (twice) according to the number of connected electronic devices 2 and which electronic device 2 is determined based on the priority of charging. Although it is controlled whether to charge the second time, charging may be performed while sequentially selecting each electronic device 2 one by one based on the determined priority order.

  In each embodiment described above, the charging timer is used to end the charging. However, when the battery reaches the full charge based on the remaining battery level detected by the remaining battery level detecting unit provided on the electronic device 2 side. In addition, charging may be terminated. In addition, although the mobile device is exemplified as the electronic device 2, the present invention is not limited thereto, and may be any electronic device 2 such as a PDA, a digital camera, a music player, or a multifunction device thereof.

  Furthermore, the “apparatus” and “machine” shown in the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.
