  In the system as described above, each terminal is used after being charged at the installation stand in advance. However, when a large number of terminals are used in a facility such as a school, the rated capacity of the power supply facility that supplies power may be exceeded when charging is simultaneously performed on all the terminals. In such a case, the user needs to perform complicated work such as switching terminals to be charged while considering the rated capacity of the power supply equipment.

  In view of such a subject, an object of the present invention is to provide a charge system and charge control server of an information terminal device which can charge a plurality of information terminal devices smoothly.

  A first aspect of the present invention relates to a charging system of an information terminal device. The charging system of the information terminal device according to the present aspect includes a plurality of installation boards on which a plurality of information terminal devices are respectively installed, and a charge control server that controls the charging operation of the information terminal device. The installation stand is configured to be communicably connected to the charge control server and to supply power to the information terminal device installed on the installation stand. The charge control server controls charge timings of the plurality of information terminal devices such that the power consumed via the plurality of installation platforms is equal to or less than a predetermined capacity.

  According to the charging system of the information terminal device according to this aspect, since the power consumed via the installation table does not exceed the predetermined capacity, even if the information terminal device is installed casually on a plurality of installation devices, It is possible to avoid exceeding the rated capacity of the power supply equipment that supplies power to these mounting bases during charging. In addition, since the charge start timing of the information terminal device is controlled by the charge control server, the user can omit the trouble of switching the information terminal device to be charged according to the charge condition of each information terminal device. It is possible to charge all the information terminal devices simply by installing the device on the installation stand. In addition, since a user for monitoring and operating the charge is not required, labor cost can be reduced. As described above, according to the charging system of the information terminal device of the present aspect, charging of a plurality of information terminal devices can be smoothly performed.

  In the charging system of the information terminal device according to the present aspect, the charge control server is configured to determine a predetermined amount of power consumed via the plurality of installation platforms among the plurality of information terminal devices installed on the plurality of installation platforms. When the number of the information terminal devices whose number is equal to or less than the capacity of the information terminal device is set as the charge object and when the charging of the one information terminal device set as the charge object is completed, the one information terminal device is removed from the charge object. One of the other information terminal devices may be included in the charge target. In this way, charging of the plurality of information terminal devices can be smoothly completed while suppressing the power consumed via the plurality of installation platforms to a predetermined capacity or less.

  Alternatively, in the charging system of the information terminal device according to the present aspect, the charge control server is configured to consume power consumed via the plurality of installation platforms among the plurality of information terminal devices installed on the plurality of installation platforms. The number of the information terminal devices whose number is equal to or less than a predetermined capacity is set as a charge target, and when the charge level of the one information terminal device set as a charge target reaches a predetermined level, the one information terminal device is It may be configured to be excluded from charging targets and to include one of the information terminal devices not to be charged in the charging targets. In this case, the charge levels of all the information terminal devices can be quickly raised to a predetermined level and set to a usable state, as compared with the case where each information terminal device is charged to full charge.

  In the charging system of the information terminal device according to the present aspect, the charge control server acquires information capable of identifying power consumption at the time of charging from the information terminal device installed on the installation stand, and based on the acquired information The charging timing of the plurality of information terminal devices may be controlled such that the power consumed via the plurality of installation platforms is less than or equal to a predetermined capacity. In this case, charging timing can be properly controlled based on the acquired power consumption of the information terminal device. For example, even when information terminal devices having different power consumptions during charging are installed on the installation stand, the charging timing can be appropriately controlled based on the power consumption acquired from each information terminal device.

  In this case, the charge control server holds a database in which identification information capable of identifying the power consumption when charging the information terminal device is associated with the power consumption when charging the information terminal device, and the installation table Power consumption corresponding to the information capable of identifying the power consumption at the time of charging acquired from the information terminal device installed in the database is extracted from the database, and the extracted power consumption is acquired as the power consumption of the information terminal device It can be done. In this case, the power consumption of the information terminal device can be smoothly acquired by referring to the database.

  In the information terminal device charging system according to the present aspect, the charge control server may be configured to set a charging time zone for the plurality of information terminal devices. In this case, for example, the information terminal apparatus can be charged during a low electricity bill such as at night or on holidays, so that the electricity bill for charging can be suppressed.

  In this case, the charge control server may be configured to set the time zone for charging the plurality of information terminal devices based on the charge state of the information terminal devices installed on the plurality of installation platforms. In this case, for example, even if it is not possible to complete charging of all the information terminal devices only in the time zone to which the midnight rate is applied, the charging time zone is set to include the time zone to which the midnight rate is applied. Thus, charging of all the information terminal devices can be reliably completed while suppressing the charge for charging.

  A second aspect of the present invention relates to a charge control server that controls the charging operation of a plurality of information terminal devices respectively installed on a plurality of installation stands. The charge control server according to the present aspect controls the charge timing of the plurality of information terminal devices such that the power consumed in the plurality of information terminal devices is equal to or less than a predetermined capacity via the plurality of installation platforms.

  According to the charge control server of the present aspect, the same effect as that of the first aspect is exhibited.

  As described above, according to the present invention, charging of a plurality of information terminal devices can be smoothly performed.

  The effects and significances of the present invention will become more apparent from the description of the embodiments shown below.

  Next, processing of the information terminal device 10 and the charge control server 30 will be described with reference to FIGS.

  FIG. 5 is a flowchart showing a process related to charging of the information terminal device 10. This process is started when the terminal 12 is connected to the terminal 22 of the installation stand 20 in each information terminal device 10.

  When the terminal 12 is connected to the terminal 22, the control unit 111 sets the information terminal device 10 in the charging standby state (S101). Specifically, the control unit 111 uses the power supplied from the terminal 22 of the installation stand 20 to supply the power to each part of the information terminal device 10 without supplying the power to the battery 113. The unit 114 is controlled.

  Subsequently, the control unit 111 transmits the charge request information to the charge control server 30 via the installation stand 20 (S102). The charge request information includes information for identifying that it is the charge request information, and a model name and a terminal number of the information terminal device 10. When the charge control server 30 receives the charge request information from the information terminal device 10, the charge control server 30 determines whether the charging of the information terminal device 10 may be started, and when the timing when the charging can be started, the information terminal device Send charging instruction information to 10. The processing of the charge control server 30 will be described later with reference to FIGS. 6 (a) to 8.

  Subsequently, the control unit 111 determines whether or not charge instruction information has been received from the charge control server 30 (S103). If charge instruction information is received (S103: YES), the control part 111 will set the said information terminal device 10 to a charge condition (S104). Specifically, the control unit 111 uses the power supplied from the terminal 22 of the installation stand 20 to supply the power to the battery 113 and to supply each unit of the information terminal device 10 with the power supply unit 114. Control. Thus, the battery 113 is charged.

  Subsequently, the control unit 111 determines whether charging of the battery 113 is completed (S105). Specifically, control unit 111 determines whether or not the charge level of battery 113 has reached the level of full charge.

  When the charging of the battery 113 is completed (S105: YES), the control unit 111 sets the information terminal device 10 to the charging completed state (S106). Specifically, the control unit 111 supplies the power to each unit of the information terminal device 10 without supplying the power to the battery 113 using the power supplied from the terminal 22 of the installation stand 20 as in the charging standby state. To control the power supply unit 114. Subsequently, the control unit 111 transmits the charge completion information to the charge control server 30 via the installation stand 20 (S107). The charge completion information transmitted in S107 includes information for identifying that it is charge completion information, and the terminal number of the information terminal device 10.

  FIG. 6A is a flowchart showing a process related to a charge request of the charge control server 30. This process is repeatedly executed for each information terminal device 10 in the charge control server 30.

  The control unit 131 determines whether or not the charging request information transmitted in S102 of FIG. 5 has been received (S201). When the charge request information is received (S201: YES), the control unit 131 determines, based on the charge request information and the charge power database, the information terminal device 10 that is the source of the received charge request information (hereinafter, "charge request terminal" ) Charging power is acquired (S202).

  The charging power database is stored in advance in the storage unit 132 of the charging control server 30, and includes items of model name and charging power as shown in FIG. 7A. In the charging power database, the model name is identification information capable of identifying the power consumption at the time of charging of the information terminal device 10, and the charging power is the power consumption at the time of charging of the information terminal device 10. The model name included in the charge request information is information that can identify the power consumption at the time of charge. In S202, the control unit 131 refers to the charge power database of FIG. 7A and extracts the charge power corresponding to the model name included in the received charge request information, thereby obtaining the charge power of the charge request terminal. get.

  Subsequently, the control unit 131 adds the charge request terminal to the charge standby list (S203). The charging standby list, as shown in FIG. 7B, indicates the information terminal device 10 in the charging standby state and indicates the priority of the information terminal device 10 to the charging state. The charging standby list is updatable stored in the storage unit 132 of the charging control server 30, and includes items of priority, terminal number, and charging power. The information terminal device 10 with a low priority value (high priority) is charged preferentially. In the example shown in FIG. 7B, the information terminal device 10 with the highest priority is the terminal indicated by the terminal number 12, and the information terminal device 10 with the lowest priority is the terminal indicated by the terminal number 15. is there. In S203, the control unit 131 registers the terminal number and charging power of the transmitting terminal in the charging standby list as the terminal with the lowest priority.

  Subsequently, the control unit 131 executes the charge instruction transmission process shown in FIG. 6B (S204). When the charge instruction transmission process ends, the process related to the charge request shown in FIG. 6A ends.

  FIG. 6B is a flowchart showing the charge instruction transmission process of the charge control server 30.

  The control unit 131 calculates the available capacity based on the charge target list and the rated capacity (S301). The charging target list indicates the information terminal device 10 in a charged state, as shown in FIG. 7C. The charge target list is updatable stored in the storage unit 132 of the charge control server 30, and includes items of a terminal number and charge power. The rated capacity is the amount of power that can be supplied from the power supply facility 43, and is stored in advance in the storage unit 132 of the charge control server 30. The rated capacity is set in advance in the charge control server 30 by the user.

  Here, the rated capacity is Wr, the total of the charging power of the information terminal device 10 in the charging state (the total of charging power of the charging target list) is Wc, the number of the installation stand 20 is N, and the information terminal device 10 in the charging state Assuming that the number of (the number of terminals in the charging target list) is n, the free capacity Wf is calculated by the following equation (1).

  Wf = Wr− {Wc + (N−n) × 5} (1)

  In the above equation (1), the power consumption of the information terminal device 10 in the standby state is uniformly set to 5 W. Also, there may be an installation stand 20 in which the information terminal device 10 is not installed and there is no need to supply 5 W necessary for the standby state to the information terminal device 10. The above equation is configured on the assumption that the information terminal device 10 is in a standby state in the (N−n) installation bases 20 in consideration of the case of being installed at any timing.

  Subsequently, the control unit 131 determines whether or not there is the chargeable information terminal device 10 in descending order of priority in the charge standby list, based on the free capacity calculated in S301 (S302). Then, when there is a chargeable information terminal device 10 (S302: YES), the control unit 131 sets the chargeable information terminal device 10 as the "charge target terminal" (S303).

  For example, in the case where the charging standby list is in the state shown in FIG. 7B, if the available capacity is 50 W, the information terminal devices 10 with priorities 1 and 2 become charging target terminals. If the free space is 30 W, only the information terminal device 10 with priority 1 is the charging target terminal. If the free capacity is 10 W, the charging target terminal is not set. When the free capacity is 20 W, the determination in S302 is NO, and the charging target terminal is not set. Even when the free capacity is 20 W, the information terminal device 10 of priority 2 may be the charging target terminal prior to the information terminal device 10 of priority 1.

  Subsequently, the control unit 131 deletes the charging target terminal from the charging standby list, and adds the charging target terminal to the charging target list (S304). And control part 131 transmits charge indication information to a charge object terminal (S305). The charging instruction information includes information for identifying that it is the charging instruction information. On the other hand, if there is no chargeable information terminal device 10 (S302: NO), the processing of S303 to S305 is skipped.

  FIG. 8 is a flowchart showing a process related to the charge completion of the charge control server 30. This process is repeatedly executed for each information terminal device 10 in the charge control server 30.

  The control unit 131 determines whether or not the charge completion information transmitted in S107 of FIG. 5 has been received (S401). When the charge completion information is received (S401: YES), the control unit 131 erases the information terminal device 10 (hereinafter referred to as "charge completed terminal") from which the received charge completion information is derived from the charge target list (S402) ). Then, the control unit 131 executes the charge instruction transmission process shown in FIG. 6B (S403). When the charge instruction transmission process ends, the process related to charge completion shown in FIG. 8 ends. By the process related to charging completion, charging of the other information terminal device 10 is started instead of charging of the charging completion terminal.

  The progress of charging of the information terminal device 10 will be described with reference to FIGS. 9 (a) to 9 (d).

  In the example shown in FIGS. 9A to 9D, 100 installation stands 20 are provided, and the numbers from 1 to 100 are added to each installation stand 20 for convenience. 9A to 9D, the information terminal device 10 included in the charge target list is surrounded by a broken line, and the information terminal device 10 included in the charge standby list is surrounded by a dotted line.

  FIG. 9A shows that the information terminal device 10 installed on the 1st to 50th installation base 20 is placed on the charging object list because the information terminal device 10 is installed on each of the 1st to 5th installation base 20. The information terminal device 10 that has been added and installed on the 51st to 53rd installation bases 20 has been added to the charging standby list. In FIG. 9A, the charge remaining amount of the information terminal device 10 installed on the first installation stand 20 is 30%, and the charge remaining amount of the information terminal device 10 installed on the second installation stand 20 is The remaining charge amount of the information terminal device 10 installed on the third to 53rd installation base 20 is 0%.

  When a predetermined time has elapsed from the state of FIG. 9A, as shown in FIG. 9B, the remaining charge amount of the information terminal device 10 installed on the first installation stand 20 becomes 100%, and this information terminal The device 10 is removed from the charge target list. Then, when the information terminal device 10 installed on the first installation stand 20 deviates from the charging target list, the free capacity calculated in S301 of FIG. 6B increases. As a result, as shown in FIG. 9C, the information terminal device 10 newly installed on the 51st installation base 20 is added to the charging object list.

  When a predetermined time passes from the state of FIG. 9C, as shown in FIG. 9D, the remaining charge amount of the information terminal device 10 installed on the second installation stand 20 becomes 100%, and this information terminal The device 10 is removed from the charge target list. Then, the information terminal device 10 newly installed on the 52nd installation base 20 is added to the charging target list.

<Effect of Embodiment 1>
According to the first embodiment, the following effects are achieved.

  Since the power consumed via the installation table 20 does not exceed the rated capacity, even if the information terminal device 10 is installed on a plurality of installation tables 20 casually, the power supply facility 43 for supplying power to the installation table 20 It is possible to avoid exceeding the rated capacity. If charging exceeding the rated capacity is performed, for example, there is a risk that the breaker of the power supply equipment 43 may fall, and in the worst case, smoke or ignition may occur. According to the first embodiment, such a risk can be avoided in advance. In addition, since the information terminal device 10 can be charged even if the rated capacity of the power supply equipment 43 is reduced, the cost for the power supply equipment 43 can be reduced.

  Further, by controlling the charge start timing of the information terminal device 10 by the charge control server 30, the information terminal device 10 having a low charge level is sequentially charged, and finally the charge levels of all the information terminal devices 10 are desired. It is considered a level. Specifically, as described with reference to FIG. 6 (b), when there is a chargeable information terminal device 10 in the charge standby list, charge instruction information is transmitted to the information terminal device 10, Charging of the information terminal device 10 is started. As described above, since charging is sequentially performed, the user can omit the trouble of switching the information terminal device 10 to be charged according to the charging status of each information terminal device 10.

  Further, even if the charge remaining amounts of the plurality of information terminal devices 10 are different from one another, charging of all the information terminal devices 10 can be performed simply by installing the plurality of information terminal devices 10 on the installation stand 20. In addition, since a user for monitoring and operating the charge is not required, labor cost can be reduced. When the user for monitoring and operating the charging becomes unnecessary, the information terminal device 10 can be charged during a low electricity bill such as at night or on holidays, so that the electricity bill can be suppressed.

  As described above, according to the charging system 100, charging of the plurality of information terminal devices 10 can be smoothly performed.

  Further, among the plurality of information terminal devices 10 installed on the plurality of installation platforms 20, the charge control server 30 is configured such that the number of information terminal devices 10 for which the power consumed via the plurality of installation platforms 20 is less than the rated capacity. Is set as the charge target. When the charge control server 30 completes the charging of the one information terminal device 10 set as the charge target, the charge control server 30 removes the one information terminal device 10 from the charge target, and charges the one information terminal device 10 not to be charged. Include in the target. Specifically, when the chargeable information terminal device 10 is present in the charge standby list, the information terminal device 10 is set as a charge target terminal. Then, when the charging is completed, the charging completed terminal is deleted from the charging target list, and the charging target terminal is set again according to the charging standby list. By repeating such control, charging of the plurality of information terminal devices 10 can be smoothly completed while suppressing the power consumed via the plurality of installation tables 20 to a predetermined capacity or less.

  Further, the charge control server 30 can appropriately calculate the free capacity based on the obtained charge power in S301 of FIG. 6B by obtaining the charge power of the information terminal device 10. Therefore, charge control server 30 can control charge timing appropriately. For example, even when the information terminal devices 10 having different power consumption at the time of charging are installed on the installation stand 20, the charge timing can be properly controlled based on the power consumption acquired from each information terminal device 10.

  Further, the charge control server 30 obtains the charge power of each information terminal device 10 by referring to the charge power database. Thereby, charge control server 30 can acquire charge electric power of information terminal device 10 smoothly.

Second Embodiment
In the charging system 100 of the second embodiment, the information terminal devices 10 of the same model are used. Therefore, in the second embodiment, since all the charging powers of the information terminal device 10 have the same value, if one charging power is stored in advance in the storage unit 132, the total Wc of the charging powers can be calculated. Therefore, in the second embodiment, the charging power database is not necessary. The other configuration and control of the second embodiment are similar to those of the first embodiment.

  FIG. 10 is a view schematically showing a screen 200 displayed on the display unit of the charge control server 30. As shown in FIG. The screen 200 includes an input area 201 for inputting a rated capacity of the power supply equipment 43, and an input area 202 for inputting power consumption (charging power) required when charging each information terminal device 10.

  The control unit 131 of the charge control server 30 displays the screen 200 on the display unit according to the display instruction of the user. The user inputs numerical values in the input areas 201 and 202 and operates the OK button. Thereby, the control unit 131 receives the rated capacity of the power supply equipment 43 and the charging power per information terminal device 10, and stores the received value in the storage unit 132. The control unit 131 performs processing using the rated capacity and the charging power stored in the storage unit 132 in S301 of FIG. 6B.

  When 25 W is input as the charging power for one information terminal device 10, 1500 W is input as the rated capacity, and the number of installation bases 20 is 100, the free capacity Wf is calculated based on the above equation (1). Is calculated by the following equation (2).

  Wf = 1500− {n × 25 + (100−n) × 5} (2)

  Substituting Wf = 0 into the above equation (2) results in n = 50. Therefore, in this example, when the number of information terminals to be charged is increased until the free capacity Wf becomes 0, it can be understood that 50 information terminal apparatuses 10 can be charged in parallel at the maximum.

  According to the second embodiment, the user can set the rated capacity of the power supply facility 43 in the charge control server 30. Therefore, even when the rated capacity of the power supply equipment 43 is changed, the information terminal device 10 can be properly charged. Also, the user can set the charging power of the information terminal device 10, and the charging control is performed with the charging power of the information terminal device 10 all being the same value. This eliminates the need for a charging power database and simplifies control.

Embodiment 3
FIG. 11A is a flowchart illustrating processing relating to a charge request of the charge control server 30 according to the third embodiment. In FIG. 11A, S211 is added between S203 and S204, as compared with the flowchart shown in FIG. 6A. The other configuration and control of the second embodiment are similar to those of the first embodiment.

  In the third embodiment, charging of each information terminal device 10 is performed in a predetermined time zone. The predetermined time zone is, for example, a time zone to which a late night charge is applied. The predetermined time zone is set in advance in the charge control server 30 by the user. Charging control server 30 waits for charging of each information terminal device 10 until the current time reaches a predetermined time zone, and in response to the current time reaching a predetermined time zone, charging control server 30 causes each information terminal device 10 to Start charging.

  As shown in FIG. 11A, when the control unit 131 adds the charge request terminal to the charge standby list (S203), the control unit 131 then determines whether the current time is included in a predetermined time zone (S211). ). If the current time is not included in the predetermined time zone (S211: NO), the process waits at S211. If the current time is included in the predetermined time zone (S211: YES), the charge instruction transmission process of S204 is executed.

  As described above, when the process of S204 is performed when the current time is included in the predetermined time zone, the charging operation of the information terminal device 10 is performed in the predetermined time zone. Thus, as described above, when the predetermined time zone is set to a time zone in which the electricity bill is cheap, such as nighttime, the electricity bill for charging the information terminal device 10 can be suppressed.

  In addition, since the process of FIG. 11A is performed for every information terminal device 10, a plurality of charge instruction transmission processes are started in the charge control server 30 at the timing when the current time becomes a predetermined time zone. Become. Therefore, in such a case, the control unit 131 may execute only one of the charging instruction transmission processes started at the same timing.

Fourth Embodiment
In the fourth embodiment, compared to the third embodiment, a charging time zone is set according to the charging state of each information terminal device 10. That is, in the third embodiment, charging is started when the current time has reached a predetermined time zone set by the user. However, in the fourth embodiment, the predetermined time is determined based on the charge state of each information terminal device 10. The charging control server 30 sets the charging time zone so as to include the time zone of Specifically, the charge control server 30 of the fourth embodiment further performs the process shown in FIG. In addition, the information terminal device 10 of the fourth embodiment transmits the necessary charge capacity (the capacity required for full charge) to the charge control server 30 at predetermined time intervals (for example, several seconds). The control unit 131 stores the received necessary charge capacity in the storage unit 132. The other configuration and control of the fourth embodiment are similar to those of the third embodiment.

  FIG. 11B is a flowchart showing a charging time zone setting process of the charge control server 30 in the fourth embodiment. This process is repeatedly performed at a predetermined time interval (for example, several seconds).

  The control unit 131 can complete the charging of these information terminal devices 10 in a predetermined time zone based on the necessary charging capacities (charging states) of all the information terminal devices 10 included in the charging standby list and the charging target list. It is determined whether or not (S501). When the charging can not be completed only in the predetermined time zone (S501: NO), the control unit 131 determines the predetermined charging state of all the information terminal devices 10 included in the charging standby list and the charging target list. The time zone is changed (S502).

  For example, as shown in FIG. 11C, when the time from the start time T1 to the end time T2 is set in advance as a predetermined time zone, if the charging is not completed only in this time zone, the start time is from T1. Change to T3. Thus, the charging time zone is set to include a predetermined time zone, and charging is performed in the set time zone. Thus, charging of all the information terminal devices 10 can be reliably performed.

  Thus, the time slot (T3 to T2) to be changed is set to include the original time slot (T1 to T2). In this way, if the original time zone is a time zone where the electricity bill is cheap, according to the time zone after change (T3 to T2), while suppressing the electricity bill for charging, all the information terminal devices 10 The charging can be completed. In addition, the end time of the charging time zone may not necessarily coincide with the ending time T2 of the predetermined time zone, and if the charging time zone includes the predetermined time zone, the end of the charging time zone The time may be set to a time later than time T2.

Fifth Embodiment
FIG. 12A is a flowchart illustrating processing relating to charging of the information terminal device 10 in the fifth embodiment. In FIG. 12A, S111 is added in place of S105 in comparison with the flowchart shown in FIG. The other configuration and control of the fifth embodiment are similar to those of the first embodiment.

  As shown in FIG. 12A, the control unit 111 determines whether or not the charge level of the battery 113 started in S104 has reached a predetermined level (S111). The predetermined level is a value smaller than the full charge level of the battery 113, and is, for example, half the charge capacity (full charge capacity) of the battery 113. The predetermined level may be held in advance by the charge control server 30, or may be set arbitrarily by the user.

  When the battery 113 is charged to a predetermined level (S111: YES), the control unit 111 sets the information terminal device 10 to the charge completed state (S106) as in the case shown in FIG. The charge completion information is transmitted (S107).

  As described above, when the information terminal device 10 is charged to a predetermined level, the timing at which the information terminal device 10 being charged is erased from the charge target list can be advanced compared to the case where the full charge is performed. As a result, the charging of the other information terminal devices 10 is started quickly, and as a result, the charging of all the information terminal devices 10 is completed quickly. Therefore, compared with the case where each information terminal device 10 is charged to a full charge, the charge levels of all the information terminal devices 10 can be quickly raised to a predetermined level and set to a usable state.

  After all the information terminal devices 10 have been charged to a predetermined level by the process as described above, next, all the information terminal devices 10 may be controlled to be charged to a fully charged level.

  For example, as illustrated in FIG. 12B, the control unit 131 of the charge control server 30 determines whether charging of a predetermined level has been completed for all the information terminal devices 10, that is, in the charge target list and the charge standby list. It is determined whether the information terminal device 10 has disappeared (S601). When the charging of the predetermined level is completed (S601: YES), the control unit 131 transmits an instruction to start the process for achieving the full charge to all the information terminal devices 10 (S602). Thereby, in all the information terminal devices 10, the process of FIG. 5 is started, and the information terminal devices 10 are charged to the level of full charge sequentially. In this way, the charge levels of all the information terminal devices 10 can be quickly set to usable predetermined levels, and if there is time, charging can be performed automatically to the level of full charge.

  Alternatively, before the processing of FIG. 12 (b) is performed, control is performed to reset the predetermined level to a value increased by a predetermined value and to charge all the information terminal devices 10 to the predetermined level after resetting. It is also good.

<Modification example>
As mentioned above, although embodiment of this invention was described, this invention is not restrict | limited at all to the said embodiment.

  For example, in the above embodiment, the information terminal device 10 is a tablet terminal, but may be another type of information terminal device such as a mobile phone or a notebook computer.

  In the above embodiment, when the charging is completed, the control unit 111 of the information terminal device 10 transmits the charge completion information to the charge control server 30, as shown in S107 of FIG. However, the present invention is not limited to this, the control unit 131 of the charge control server 30 transmits information for confirming the charge state to the information terminal device 10 at predetermined time intervals, and the control unit 111 of the information terminal device 10 When the information to be confirmed is received, the charge state of the information terminal device 10 may be transmitted to the charge control server 30.

  Moreover, in the said embodiment, although the model name of the information terminal device 10 was contained in charge request information, the power consumption at the time of charge of the information terminal device 10 may be included. In this case, since the control unit 131 of the charge control server 30 can directly acquire the charge power of each information terminal device 10 from the received charge request information, the charge power database becomes unnecessary.

  Moreover, in the said embodiment, although the charge control server 30 controlled the charge operation of the information terminal device 10 by communicating with the information terminal device 10, control of the charge operation is not restricted to this. For example, the control unit may be provided on the installation stand 20, and the charge control server 30 may control the charging operation of the information terminal device 10 by communicating with the control unit of the installation stand 20. In this case, the control unit of the installation stand 20 may simply relay the communication between the information terminal device 10 and the charge control server 30, or based on the communication with the charge control server 30, the information terminal device The charge of 10 may be controlled.

  Moreover, in the said Embodiment 3, the charge control server 30 may be equipped with charge priority mode and cost priority mode. For example, when the charge priority mode is set, the control unit 131 does not perform the process of S211 shown in FIG. 11A, and when the cost priority mode is set, the control unit 131 performs the process shown in FIG. As shown in a), the process of S211 is performed. Thereby, when the charging priority mode is set, the charging operation is started even if the current time is not in the predetermined time zone. On the other hand, when the cost priority mode is set, the charging operation is started when the current time is included in a predetermined time zone. When such control is performed, the user can give priority to either quick charging or suppression of the electricity bill by switching between the two modes.

  In addition to the above, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
