In the following description, it is assumed that the power supply device 20 is provided in the dining room at home. In this case, the dining room becomes the irradiation range of the infrared beam and becomes the power supply area where power can be received.

FIG. 2 is a block diagram showing the configuration of the power supply management server 10. The power supply management server 10 includes a control device 11, a storage device 12, and a communication device 13. Each element of the power supply management server 10 is connected to each other by a single bus or a plurality of buses. The term "device" in the present application may be read as another term such as a circuit, a device, or a unit. Further, each element of the power supply management server 10 may be composed of a single or a plurality of devices, and some elements of the power supply management server 10 may be omitted.

The control device 11 is a processor that controls the entire power supply management server 10, and is composed of, for example, a single chip or a plurality of chips. The control device 11 is composed of, for example, a central processing unit (CPU) including an interface with peripheral devices, an arithmetic unit, registers, and the like. In addition, a part or all of the functions of the control device 11 are realized by hardware such as DSP (Digital Signal Processor), ACIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), FPGA (Field Programmable Gate Array). You may. The control device 11 executes various processes in parallel or sequentially.

The communication device 13 is a device that communicates with another device via the communication network NET. The communication device 13 is also referred to as, for example, a network device, a network controller, a network card, or a communication module. Specifically, the communication device 13 executes communication with the power supply device 20 via the communication network NET.

FIG. 3 is a block diagram showing a function realized by reading and executing a program stored in the storage device 12 in the control device 11.
As shown in the figure, the control device 11 functions as a management unit 11A, an estimation unit 11B, and a schedule unit 11C. The management device 110 is realized by the management unit 11A, the estimation unit 11B, and the schedule unit 11C.

The management unit 11A manages the power supply history information indicating the power supply history for each of the plurality of power receiving devices 30 including the power storage and power receiving device 30c capable of storing electricity. Specifically, the management unit 11A stores the power supply history information in the power supply history table TBLa5 stored in the storage device 12.

The estimation unit 11B estimates the amount of electric power required by the power storage and power receiving device 30c based on the schedule information indicating the schedule of actions of the user who uses the power storage and power receiving device 30c. The schedule information shows the user's behavior for each time zone, and is stored in the user schedule table TBLa1.

The schedule unit 11C generates a power supply schedule based on the estimation result of the estimation unit 11B, the power supply history information, and the priority order of power supply to the plurality of power receiving devices 30.
According to this management device 110, the amount of power consumed by the power storage and power receiving device 30c is estimated in consideration of the schedule of the user who uses the power storage and power receiving device 30c. You can identify whether it is good or not. As a result, it becomes possible to efficiently supply power to a device that requires power supply in relation to the behavior of the user.

More specifically, the schedule information indicates the user's behavior for each time zone, and the estimation unit 11B refers to the relational information indicating the relationship with the power storage receiving device 30c used in association with the behavior, and the schedule information. The usage time in which the storage power receiving device 30c is used is specified based on the above, and the amount of power required by the storage power receiving device 30c according to the user's behavior is estimated based on the specified usage time and power consumption. .. The relationship information is stored in the relationship table TBLa2. According to this aspect, since the time for using the power storage receiving device can be specified from the behavior schedule of the user, the power supply schedule is set so that the amount of power consumed during use is stored in the storage power receiving device 30c before the start of use. It becomes possible to generate.

The user schedule table TBLa1 stores schedule information in which the user's action and the time zone in which the user executes the action are associated with each other. FIG. 4 shows an example of the stored contents of the user schedule table TBLa1. In this example, it is remembered that the user will take a walk during the time period from 7:00 to 8:00 on December 20th. The schedule information is transmitted from an information processing device such as a user's smartphone to the power supply management server 10. Here, it is preferable that the schedule information stored in the user schedule table TBLa1 is a combination of schedules registered in a plurality of schedule applications. For example, in a company, business schedules may be managed by a computer in the company, in private, schedules may be managed by a smartphone, and in a hobby circle, schedules may be managed by a scheduler provided on the cloud. Although the schedules are managed by independent schedule applicators, the schedules managed by each schedule applicator may be synchronized with the schedule information of the power supply management server 10. In this case, the schedule can be integrated and centrally managed, which improves convenience.

In the relation table TBLa2, the behavior of the user and the power receiving device identification information of the power receiving device 30 used in the behavior of the user are stored in association with each other. The power receiving device identification information is information for uniquely identifying the power receiving device 30. For example, the power receiving module number uniquely assigned to the power receiving module corresponds to the power receiving device identification information. FIG. 5 shows an example of the stored contents of the relation table TBLa2.

It is assumed that the power receiving device identification information "AC0001" corresponds to a smartphone and the power receiving device identification information "AC0002" corresponds to a tablet terminal. In the example shown in FIG. 5, since the “company” is associated with the power receiving device identification information “AC0001” and the power receiving device identification information “AC0002”, when the user goes to work at the company, the smartphone and the tablet terminal are connected. used.
For the storage in the relation table TBLa2, the user may use an information processing device such as a smartphone to transmit the correspondence between the action and the power receiving device 30 to be used to the power supply management server 10.

In the power consumption table TBLa3, the power receiving device identification information and the power consumption of the power receiving device 30 corresponding to the power receiving device identification information are stored in association with each other. FIG. 6 shows an example of the stored contents of the power consumption table TBLa3. In the example shown in FIG. 6, since the power receiving device identification information “AC0002” of the tablet terminal and the power consumption X2 are associated with each other, it can be seen that the power consumption of the tablet terminal is “X2”.

In the power supply schedule table TBLa4, the future time zone and the power receiving device identification information of the power receiving device 30 to be supplied are stored in association with each other. FIG. 7 shows an example of the stored contents of the power supply schedule table TBLa4.
In the power supply history table TBLa5, the past time zone and the power receiving device identification information of the power receiving device 30 to be supplied are stored in association with each other. FIG. 8 shows an example of the stored contents of the power supply history table TBLa5.

In the management table TBLa6, the power receiving device identification information, the power feeding device identification information, and the power feeding state information are stored in association with each other. FIG. 9 shows an example of the stored contents of the management table TBLa6.
The power receiving device identification information is information that uniquely identifies the power receiving device 30, and corresponds to, for example, a power receiving module number uniquely assigned to the power receiving module.
The power feeding device identification information is information that uniquely identifies the power feeding device 20. By storing the electric power receiving identification information and the power feeding device identification information in association with each other in the management table TBLa6, it is possible to know from which power feeding device 20 the power receiving device 30 is to be supplied.

Further, when there is no power receiving device identification information corresponding to the power receiving device identification information in the management table TBLa6, it means that the power receiving device 30 corresponding to the power receiving device identification information is located outside the power feeding area. For example, since the power receiving device identification information "AS0101" shown in FIG. 9 is not associated with the power receiving device identification information, the power receiving device 30 corresponding to the power receiving device identification information "AS0101" may not be in a state where power can be supplied. I understand.

The power supply status information indicates the power supply status of the power receiving device 30. In the power supply state, the power supply device 20 irradiates a beam toward the power receiving device 30 to supply power, and the power supply device 20 receives a power supply start request but waits for power supply to the power receiving device 30. There are "standby", "standby", and "stopping" in which the power feeding device 20 does not irradiate the beam toward the power receiving device 30 and does not supply power.

The power supply status information includes a power supply flag indicating "power supply", a stop flag indicating "stopped", and a standby flag indicating "waiting". Each flag is valid at "1" and invalid at "0". The stopped flag is set to "1" when the power receiving device 30 is not located in the irradiation range of the power feeding device 20 or when the power receiving device 30 is located within the irradiation range of the power feeding device 20 but there is no request for power supply. be. Further, the standby state of power supply corresponds to the case where the maximum value of the power supply power is exceeded when power is further supplied from the power supply device 20.

In the priority list PL, the order in which power supply is prioritized is recorded. In this example, the constant power receiving device 30a has a higher priority of power supply than the power receiving device 30b and the storage power receiving device 30c each time. This is because the constant power receiving device 30a cannot operate unless power is constantly supplied. Further, the power receiving device 30b has a higher priority of power supply than the power storage receiving device 30c each time. This is because the power storage device 30c is not used immediately but is used after being charged in the power supply area, but the power receiving device 30b needs to be operated immediately when the power switch is turned on each time.

Further, the estimation unit 11B described above estimates the consumption tendency of the storage battery for each of the plurality of power storage and receiving devices 30c, and the schedule unit 11C estimates the power supply priority for the plurality of storage and power receiving devices 30c based on the estimated consumption tendency of the storage battery. Is determined, and the result is written in the priority list PL. By determining the power supply priority in this way, it is possible to raise the power supply priority of the device that consumes the power of the storage battery in a short time to that of the device that consumes the power of the storage battery for a long time.

More specifically, the estimation unit 11B charges the charging rate of each of the plurality of power storage and receiving devices 30c immediately before moving from the inside of the power supply area to the outside of the power supply area and the charge immediately after moving from outside the power supply area to the inside of the power supply area. Estimate the consumption tendency of the storage battery based on the rate. In this case, the power storage receiving device 30c stores the charge rate of the storage battery in the memory 32C of the power receiving module 32 at the timing of moving from the power feeding area to the outside of the power feeding area. Then, the charge rate of the storage battery is acquired at the timing when the power storage receiving device 30c moves from the outside of the power supply area to the inside of the power supply area, and the charge rate notification including both charge rates is transmitted from the power storage / power receiving device 30c to the power supply device 20. Then, the power supply device 20 transmits the charge rate notification to the power supply management server 10, so that the power supply management server 10 can grasp the charge rate.

Further, the schedule unit 11C modifies the power supply schedule according to the operating status of the plurality of power receiving devices 30. When there is a discrepancy between the actual power supply and the power supply schedule, the power supply schedule is dynamically modified according to the operating status of the plurality of power receiving devices 30, so that the power supply efficiency can be improved.

When the direction from the beam irradiating device 22 toward the storage power receiving device 30c1 is the first direction and the direction from the beam irradiating device 22 toward the storage power receiving device 30c2 is the second direction, the processing device 21 is the second direction with respect to the beam irradiating device 22. The control data that specifies one direction and the control data that specifies the second direction are supplied in time division. When power is supplied to a plurality of power receiving devices 30 located in the irradiation range, the number of infrared beams that can be simultaneously irradiated by the beam irradiating device 22 is one by irradiating each power receiving device 30 with an infrared beam in a time-division manner. At any one, it is possible to supply power to a plurality of power receiving devices 30.

<2. Power supply schedule>
Next, the pre-registration operation, the power supply schedule generation operation, and the power supply schedule correction operation will be described separately in relation to the power supply schedule.

<2-1: Pre-registration>
In the power supply system 1, the power supply management server 10 controls which power receiving device 30 is irradiated with the infrared beam to supply power to the power supply device 20. This control is executed based on the power receiving device identification information assigned to each power receiving device 30. Therefore, the user of the power receiving device 30 needs to notify the power supply management server 10 of the power receiving device identification information of the power receiving device 30.
There are two methods for registering the power receiving device identification information in the power supply management server 10. The first method is a method of registering the power receiving device identification information in the power supply management server 10 via the power supply device 20.

<2-2: Generation of power supply schedule>
FIG. 16 is a flowchart for explaining an operation of generating a power supply schedule in the power supply management server 10.
First, the control device 11 specifies the power receiving device identification information of the power storage power receiving device 30c used for the action recorded in the user schedule table TBLa1 (Sb1). For example, in the user schedule table TBLa1 shown in FIG. 4, "company" is recorded as an action corresponding to the time zone "December 20, 9:00 to 18:00". In this case, the control device 11 refers to the relation table TBLa2 and specifies the power receiving device identification information “AC0001” of the smartphone and the power receiving device identification information “AC0002” of the tablet terminal as the power receiving device identification information corresponding to the “company”. do.

Next, the control device 11 estimates the amount of electric power required for the scheduled action based on the scheduled use time and the power consumption of the specified power storage and receiving device 30c (Sb2). In the example shown in FIG. 4, assuming a "company" in the time zone "December 20, 9:00 to 18:00", a smartphone and a tablet terminal are specified as the power storage receiving device 30c. The usage time is 9 hours. The control device 11 refers to the power consumption table TBLa3 and acquires the power X1 of the smartphone and the power X2 of the tablet terminal. Then, the control device 11 estimates that the amount of electric power required by the smartphone is "9.X1" in the behavior of working at the "company", and the amount of electric power required by the tablet terminal is "9.X2". Is presumed to be.

Next, the control device 11 calculates the time and power required to supply the estimated amount of power to the power storage receiving device 30c. In the case of the smartphone described above, assuming that the power is supplied by the electric power Y, the time required for the power supply is “9 ・ X2 / Y”.

Next, the control device 11 refers to the power supply history table TBLa5, estimates the time zone in which the power receiving device 30b is used each time, and specifies the power required for power supply (Sb4). The power receiving device 30b corresponds to, for example, a microwave oven, a cooler, a vacuum cleaner, or the like. Since the operation of these devices is used in daily life, it reflects the user's life such as using a microwave oven for breakfast and cleaning in the morning. Therefore, by paying attention to the time zone used, the day of the week used, etc., it is possible to estimate in which time zone it is used. The control device 11 analyzes the power supply history recorded in the power supply history table TBLa5 by a statistical method such as autocorrelation analysis, estimates the time zone used for each power reception device 30b, and estimates the time zone used for each power reception device 30b. The power is specified every 30b.

Next, the control device 11 refers to the power supply history table TBLa5 and specifies the power required for power supply of the constant power receiving device 30a (Sb5). After that, the control device 11 sets the priority of power supply in the order of the power receiving device 30a at all times, the power receiving device 30b each time, and the power storage receiving device 30c, and supplies power so that charging is completed before the storage power receiving device 30c is scheduled to be used. The power supply schedule generated by scheduling is stored in the power supply schedule table TBLa4 (Sb6).
The control device 11 executes power supply to the power receiving device 30 according to the power supply schedule.

<2-3: Correction of power supply schedule>
As described above, the control device 11 schedules the power supply to the power receiving device 30 according to the schedule of the user, but the user may not act according to the schedule. For example, a walk is scheduled from 7 o'clock, but the weather is bad and the person does not go out, or the power switch of the power receiving device 30b is turned on and power supply starts regardless of the schedule.

In this way, the actual power supply does not always match the power supply schedule. On the other hand, as described above, in the power supply schedule, the future behavior of the user is estimated, and the power supply power is allocated so that the power storage and receiving device 30c can be efficiently charged based on the estimation result. Therefore, in the present embodiment, when the actual power supply does not match the power supply schedule, the power supply schedule is dynamically modified.

FIG. 17 is a flowchart for explaining an operation of modifying the power supply schedule in the power supply management server 10.
The control device 11 of the power supply management server 10 determines whether or not the actual power supply and the power supply schedule match (Sc1), and if the actual power supply and the power supply schedule do not match, the control device 11 is not scheduled. It is determined whether or not there is a power supply request from the power receiving device 30b each time (Sc2). When a power supply request is received from the power receiving device 30b each time it is not scheduled, the determination result in step Sc2 is "YES", and the control device 11 determines whether or not the total power including the power supply request exceeds the maximum value of the power supply power. Is determined (Sc3).

If the total power exceeds the maximum value of the power supply, it is not possible to supply power to all the power receiving devices 30 that request power supply. Therefore, the control device 11 cancels the power supply of the power storage and receiving device 30c in ascending order of priority, and adjusts the total power so that it is equal to or less than the maximum value of the power supply power (Sc4). Specifically, the control device 11 reads the priority list PL from the storage device 12 and determines the power storage receiving device 30c for temporarily stopping the power supply according to the priority list PL. Further, the control device 11 updates the power supply state information of the management table TBLa6, and changes the power supply state to the electricity storage power receiving device 30c in which the power supply state is changed from the power supply to the standby state via the power supply device 20. Send a waiting notification to indicate. The power storage receiving device 30c that has received the standby notification can recognize that the stoppage of power supply is not caused by a malfunction such as a communication failure. Therefore, since the power storage receiving device 30c in standby does not transmit the power supply request again, the processing load of the power supply management server 10 can be reduced.

Next, when there is no power supply request from the power receiving device 30b each time it is not scheduled and the determination result in step Sc2 is NO, the control device 11 determines whether the power receiving device 30b was used at the scheduled time each time (Sc5). .. If the power receiving device 30b is not used at the scheduled time each time, the control device 11 advances the power supply schedule of the storage power receiving device 30c in descending order of priority, and adjusts the total power so that it is equal to or less than the maximum value of the power supply power. (Sc6).

When the determination result of step Sc3 is NO, the process of step Sc4 is completed, the determination result of step Sc5 is YES, or the process of step Sc6 is completed, the control device 11 is based on the current power supply state. , Generate a power supply schedule (Sc7).
