[0003] [Patent Document 1] Japanese Patent Publication No. 2022-149810 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-described usage status management system still has room for improvement in terms of reducing the burden on facility employees who use the system. [Means for solving the problem]

[0005] Various aspects of a usage status management system for solving the above problems will be described below. [Mode 1] A usage status management system includes a plurality of terminals worn by a plurality of users who use a facility, a power transmission device installed in the facility and transmitting power to the plurality of terminals via spatial transmission, and a management device that manages the usage status of the facility by the plurality of users, wherein the terminals have a first communication unit configured to be able to communicate with at least the power transmission device, the first communication unit transmitting location information indicating the current location of the terminal, and a power receiving unit receiving power transmitted from the power transmission device, the power transmission device has a second communication unit configured to be able to communicate with both the terminals and the management device, and a power transmission unit that transmits power toward a position indicated by the received location information of the plurality of terminals, and the management device has a third communication unit configured to be able to communicate with at least the power transmission device, and a situation estimation unit that estimates the density of the users in the facility based on the received location information of the plurality of terminals.

[0006] The usage status management system estimates the user density based on the location information of multiple terminals. For example, if multiple terminals are concentrated in a small area, the usage status management system estimates the user density as high. On the other hand, if multiple terminals are dispersed over a wide area based on the location information of the terminals, the usage status management system estimates the user density as low. In this way, the usage status management system can estimate the user density within a facility without requiring visual confirmation by facility employees. Furthermore, because power is supplied to the terminals from the power transmission device via spatial transmission, maintenance due to terminal battery exhaustion, etc., is not required. In this respect, the usage status management system can reduce the burden on facility employees who use the system.

[0007] [Aspect 2] When the facility has multiple areas, at least one power transmission device is installed for each of the areas, and the situation estimation unit of the management device estimates the user density for each of the areas. This is a usage status management system described in [Aspect 1].

[0008] The usage management system can inform users when certain areas of a facility are less crowded than others, or encourage users who are staying in a crowded area to move to a less crowded area.

[0009] [Aspect 3] A usage status management system as described in [Aspect 1] or [Aspect 2], wherein the terminal has a vital sensor that detects the user's vital information, and the management device has a memory unit that stores the multiple users and the multiple terminals in association with each other, and a health condition determination unit that determines, based on the vital information transmitted from the terminal, changes in the health condition of the user corresponding to the terminal that transmitted the vital information.

[0010] The usage status management system determines changes in the user's physical condition based on vital sign information transmitted from the terminal. This allows the usage status management system to provide a sense of security to users using the facility. Furthermore, the usage status management system can use the power transmitted from the power transmission device to provide the power required to drive the vital sign sensor in the terminal.

[0011] [Aspect 4] When one of the plurality of terminals is an optional terminal, the situation estimation unit of the management device generates, as notification information, information encouraging the user wearing the optional terminal to move when there are multiple other terminals near the optional terminal or when the position of the optional terminal has not changed over a determination time, and the third communication unit of the management device transmits the notification information to the optional terminal, and the terminal has a display unit that displays the received notification information.A usage status management system described in any of [Aspect 1] to [Aspect 3].

[0012] The usage management system can eliminate imbalances in user facility usage by displaying notification information encouraging movement on the display unit of a device worn by at least one of the users who are crowded together and the users who are not moving.

[0013] [Aspect 5] A usage status management system described in any of [Aspect 1] to [Aspect 4], wherein the management device has a chat generation unit that generates chat rooms available to two or more users belonging to the same group when there are two or more users among the plurality of users who use the facility as a group, the terminal has a display unit that displays posted information posted to the chat rooms available to the users, and an input unit that is operated when entering the posted information into the chat room, and the third communication unit of the management device, when receiving the posted information from the terminal, transmits the posted information to the terminal corresponding to another user who belongs to the same group as the user corresponding to the terminal.

[0014] When two or more users belonging to the same group are apart within a facility, the two or more users can communicate with each other. Therefore, the usage status management system can improve the convenience of users who use the facility. [Effects of the Invention]

[0015] A usage status management system can reduce the burden on employees at facilities that use the system. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a block diagram showing the configuration of the usage status management system. [Figure 3] FIG. 3 is an example of user information stored in the memory of the management device. [Figure 4] FIG. 4 is an example of facility usage information stored in the memory of the management device. DETAILED DESCRIPTION OF THE INVENTION

[0017] An embodiment of the usage status management system will be described. <Facilities> FIG. 1 shows a facility that employs a usage status management system 10. In this embodiment, the facility is a hot spring facility. The facility has multiple areas AR, including a first area AR1, a second area AR2, a third area AR3, and a fourth area AR4. The multiple areas AR of the facility include, for example, the facility's reception space, rest space, changing room, large bath, open-air bath, and sauna room. The facility's reception space and rest space are shared areas for both men and women, while the rest space, changing room, large bath, open-air bath, and sauna room are separate areas for men and women. Note that the multiple areas AR do not need to be clearly separated by walls, doors, etc.

[0018] <Usage Status Management System 10> As shown in FIGS. 1 and 2, the usage status management system 10 includes a plurality of terminals 20, a plurality of power transmission devices 30, a management device 40, and a display device 60.

[0019] <Terminal 20> The terminal 20 is configured to be wearable on the wrist of a user, for example. The terminal 20 is preferably configured as one unit with a locker key installed in an area AR corresponding to a changing room. The terminal 20 in FIG. 1 indicates the location of the terminal 20 worn by the user. For example, FIG. 1 shows that there are four users in the first area AR1, each wearing four terminals 20. FIG. 1 also shows that three users are relatively close to each other in the first area AR1, and one user is located far away from the three users.

[0020] As shown in FIG. 2, the terminal 20 includes a first communication unit 21, a power receiving unit 22, a storage battery 23, a vital sensor 24, a display unit 25, an input unit 26, and a first control unit 27. The first communication unit 21 has a communication antenna 211. The first communication unit 21 performs data communication with the power transmitting device 30 via the communication antenna 211. The communication standard of the first communication unit 21 may be Bluetooth (registered trademark), Wi-Fi (registered trademark), ZigBee (registered trademark), or the like. In another embodiment, the first communication unit 21 may be configured to perform data communication with the management device 40.

[0021] The power receiving unit 22 has a power receiving antenna 221. The power receiving unit 22 receives a power transmission signal transmitted over space from the power transmitting device 30 via the power receiving antenna 221. The power transmission signal includes microwaves. The power receiving unit 22 converts the power transmission signal transmitted from the power transmitting device 30 into DC power via a rectifier circuit and a transformer circuit (not shown). In this way, the power receiving unit 22 receives the power transmitted from the power transmitting device 30.

[0022] The storage battery 23 is, for example, a lithium-ion secondary battery. The storage battery 23 is supplied with DC power converted by the power receiving unit 22. As a result, the storage battery 23 is charged by contactless power supply. Therefore, as long as the terminal 20 of this embodiment is placed within the power transmission range of the power transmitting device 30, the storage battery 23 will not basically run out of power.

[0023] The vital sensor 24 detects vital information of the user wearing the terminal 20. As an example, the vital information includes one of heart rate, respiratory rate, body temperature, blood pressure, and blood oxygen saturation. The vital sensor 24 transmits the detected vital information to the first control unit 27.

[0024] The display unit 25 is, for example, a liquid crystal display. The size of the display unit 25 is preferably such that the user does not feel uncomfortable when wearing the terminal 20. The input unit 26 may be one or more physical buttons, or may be a touch display. In the latter case, the display unit 25 and the input unit 26 are configured as a single unit. The input unit 26 generates posted information, which will be described later, in response to a user operation.

[0025] The first control unit 27 is an electronic control device configured with a processing circuit including a CPU and a memory. Programs and data are stored in the memory of the first control unit 27. In the first control unit 27, the CPU executes the control programs stored in the memory. In this way, the first control unit 27 performs communication control to control the first communication unit 21, display control to control the display unit 25, and charging control to control the power receiving unit 22 and the storage battery 23.

[0026] In the communication control, the first control unit 27 causes the first communication unit 21 to transmit and receive various information. Specifically, in the communication control, the first communication unit 21 transmits location information indicating the current location of the terminal 20 to the power transmitting device 30. The location information is, for example, a beacon signal. Furthermore, the first communication unit 21 transmits vital information detected by the vital sensor 24 to the power transmitting device 30, and transmits posted information corresponding to operations on the input unit 26 to the power transmitting device 30. When transmitting information, the first communication unit 21 also transmits information identifying the terminal 20, such as a terminal ID and a MAC address. Furthermore, in the communication control, the first communication unit 21 receives notification information, posted information, additional information, and the like transmitted from the power transmitting device 30. As will be described in detail later, the notification information, posted information, and additional information are information that should be notified to the user wearing the terminal 20.

[0027] In display control, first control unit 27 causes various types of information to be displayed on display unit 25. In detail, first control unit 27 causes display unit 25 to display vital information, notification information, posted information, and additional information.

[0028] In the terminal 20, the hardware of the terminal 20, such as the first communication unit 21, the vital sensor 24, the display unit 25, and the input unit 26, operates using power supplied from the storage battery 23. That is, the hardware of the terminal 20 operates using power transmitted via space from the power transmitting device 30. Therefore, even if the terminal 20 includes hardware that consumes high power, the hardware can operate stably. The terminal 20 may also include other hardware for realizing other functions.

[0029] <Power transmission device 30> 1, a plurality of power transmission devices 30 are installed in a plurality of areas AR of the facility, respectively. As an example, the power transmission devices 30 are preferably installed on the ceilings of the areas AR. In this embodiment, one power transmission device 30 is installed for one area AR, but in other embodiments, two or more power transmission devices 30 may be installed for one area AR.

[0030] As shown in FIG. 2, the power transmitting device 30 includes a second communication unit 31, a power transmitting unit 32, and a second control unit 33. The second communication unit 31 has a communication antenna 311. The second communication unit 31 performs data communication with multiple terminals 20 present in the same area AR via the communication antenna 311. The power transmission unit 32 has a power transmission antenna 321. The power transmission unit 32 converts power supplied from a power source (not shown) into a power transmission signal. Then, the power transmission unit 32 transmits the power transmission signal to the terminal 20 via the power transmission antenna 321. In this way, the power transmission unit 32 supplies power to the terminal 20 by spatial transmission. In other words, the power transmission unit 32 supplies power to the terminal 20 by microwave power feeding.

[0031] The second control unit 33 is an electronic control device configured with a processing circuit including a CPU and memory. Programs and data are stored in the memory of the second control unit 33. In the second control unit 33, the CPU executes the control programs stored in the memory. In this way, the second control unit 33 performs communication control to control the second communication unit 31 and power transmission control to control the power transmission unit 32.

[0032] In the communication control, the second control unit 33 causes the second communication unit 31 to transmit and receive various information. In detail, the second communication unit 31 transmits location information, vital information, posted information, and the like transmitted from the terminal 20 to the management device 40, and transmits notification information, posted information, additional information, and the like transmitted from the management device 40 to an appropriate terminal 20. In other words, the second communication unit 31 relays information transmitted and received between the terminal 20 and the management device 40.

[0033] In the power transmission control, the second control unit 33 identifies the location or direction of the terminal 20 based on the received location information of the terminal 20. Then, the second control unit 33 causes the power transmitting unit 32 to transmit a power transmission signal toward the location or direction of the terminal 20. In this way, the power transmitting device 30 can improve the efficiency of wireless power supply to the terminal 20.

[0034] <Management device 40> 2, the management device 40 includes a third communication unit 41 and a control device 42. Unlike the power transmission device 30, only one management device 40 needs to be provided in a facility.

[0035] The third communication unit 41 is communicably connected to the second communication unit 31 of the power transmitting device 30. In this manner, the third communication unit 41 performs data communication with the power transmitting device 30. In this embodiment, the third communication unit 41 is connected to the second communication unit 31 by wire. In other embodiments, the third communication unit 41 may be connected to the second communication unit 31 wirelessly.

[0036] The control device 42 is an electronic control device configured with a processing circuit including a CPU 421 and a memory 422. Programs and data are stored in the memory 422 of the control device 42. In the control device 42, the CPU 421 executes the control program stored in the memory 422. In this way, the control device 42 functions as a communication control unit 51, a situation estimation unit 52, a physical condition determination unit 53, a chat generation unit 54, an additional information generation unit 55, and a display control unit 56. The memory 422 corresponds to a "storage unit."

[0037] As shown in FIGS. 3 and 4, the data stored in the memory 422 of the control device 42 includes user information and facility usage information. As shown in FIG. 3, user information is information about a user. For example, the user information is registered when the user uses a facility for the first time. The user information includes, for example, a user ID, the user's name, the user's date of birth, and the user's address. The user ID is a unique ID that is associated with one user.

[0038] As shown in FIG. 4, facility usage information is information that associates a user who uses a facility with a terminal 20 worn by the user. The facility usage information is registered when a user starts using a facility and deleted when the user finishes using the facility. The facility usage information includes a terminal ID, a user ID, and a group ID. The terminal ID is a unique ID that is linked to one terminal 20. The group ID is an ID that is set when a facility is used by a group. In the example shown in FIG. 4, the group IDs of the user with the user ID "U100" and the user with the user ID "U101" are both "G001". In other words, in the example shown in FIG. 4, the user with the user ID "U100" and the user with the user ID "U101" belong to the same group. The group here is, for example, a group made up of family members.

[0039] <Communication control unit 51> The communication control unit 51 causes the third communication unit 41 to transmit and receive various types of information. Specifically, the communication control unit 51 receives location information, vital sign information, and posted information of a plurality of terminals 20 transmitted from a plurality of power transmission devices 30. Furthermore, the third communication unit 41 transmits the notification information, posted information, and additional information to the power transmission device 30. At this time, the third communication unit 41 also transmits information for identifying the terminal 20, such as a terminal ID and a MAC address, so that the notification information, posted information, and additional information can be received only by the terminals 20 that are intended to receive them.

[0040] <Situation Estimation Unit 52> The situation estimation unit 52 estimates the usage status of users in each of the multiple areas AR based on the location information of the multiple terminals 20 transmitted via the multiple power transmission devices 30. The situation estimation unit 52 acquires location information of one or more terminals 20 present in the first area AR1 from the power transmission devices 30 installed in the first area AR1. Next, the situation estimation unit 52 estimates the usage status of users in the first area AR1 based on the acquired location information of the one or more terminals 20. For example, the situation estimation unit 52 calculates the user density in the first area AR1 by dividing the number of terminals 20 present in the first area AR1 by the floor area of ​​the first area AR1. Then, the situation estimation unit 52 similarly calculates the user density for the second area AR2, the third area AR3, and the fourth area AR4.

[0041] Here, the user density of the first area AR1 is a value indicating the usage status of users in the first area AR1. The greater the number of users present in the first area AR1, the greater the user density of the first area AR1. In other words, a high density indicates a high usage status of the corresponding area AR, and a low density indicates a low usage status of the corresponding area AR. Note that if there are no terminals 20 in an area AR, the user density in one area AR is "0."

[0042] When a first area AR1 is further divided into a plurality of subdivided areas, the situation estimation unit 52 may calculate the user density in one subdivided area by dividing the number of terminals 20 present in one subdivided area of ​​the first area AR1 by the floor area of ​​the subdivided area. In this case, the situation estimation unit 52 calculates the user density for each of the plurality of subdivided areas in one area AR. This allows the situation estimation unit 52 to grasp the user usage status in one area AR in more detail. For example, when a large public bath is defined as an arbitrary area AR, the plurality of subdivided areas of the area AR are an area with a first bathtub, an area with a second bathtub, an area with a jet bath, and an area with a washing area.

[0043] The situation estimation unit 52 may determine the congestion state of the area AR based on the calculated user density. For example, if the user density in the first area AR1 is less than a first determination value, the situation estimation unit 52 determines that the first area AR1 is not congested. Furthermore, if the user density in the first area AR1 is equal to or greater than the first determination value and less than a second determination value greater than the first determination value, the situation estimation unit 52 determines that the first area AR1 is slightly congested. Furthermore, if the user density in the first area AR1 is equal to or greater than the second determination value, the situation estimation unit 52 determines that the first area AR1 is very congested.

[0044] When there is a bias in the usage patterns of users within a facility, it is desirable to eliminate this bias. Therefore, when multiple terminals 20 are present near one of the multiple terminals 20 (hereinafter also referred to as "arbitrary terminals"), the situation estimation unit 52 generates notification information for the user wearing the arbitrary terminal. The notification information here includes information for encouraging the user to move to another area AR or to another sub-area, and information for identifying the terminal 20 worn by the user to whom the notification information should be transmitted. The latter information may be the terminal ID and MAC address described above. Furthermore, when the location of the arbitrary terminal has not changed over the determination time, the situation estimation unit 52 similarly generates notification information for the user wearing the arbitrary terminal. The determination time is preferably set appropriately depending on the area AR in which the user is located. The determination time may also be set based on the user's age, physical condition, and other information contained in the user information. As an example, the determination time may be 10 minutes or more.

[0045] When the situation estimation unit 52 generates the alarm information, the communication control unit 51 causes the third communication unit 41 to transmit the alarm information. Specifically, the alarm information transmitted from the third communication unit 41 is transmitted to the power transmission device 30 provided in the area AR where the terminal 20 worn by the user to whom the alarm information is to be transmitted is located. Then, the power transmission device 30 transmits the alarm information to the terminal 20 worn by the user to whom the alarm information is to be transmitted. As a result, the alarm information is displayed on the display unit 25 of the terminal 20 worn by the user to whom the alarm information is to be transmitted.

[0046] <Health Condition Assessment Unit 53> The physical condition determination unit 53 determines a change in the physical condition of the user wearing the terminal 20 that is the source of the vital information, based on the vital information of the multiple terminals 20 transmitted via the multiple power transmission devices 30. The physical condition determination unit 53 determines a change in the user's physical condition based on the user's heart rate as vital information and the user's age as user information. If it is determined that the user's physical condition is deteriorating, notification information is generated for the user wearing the terminal 20 that detects the vital information. The notification information here is information that makes the user aware of the deterioration of their physical condition.

[0047] When the physical condition determination unit 53 generates the notification information, the communication control unit 51 causes the third communication unit 41 to transmit the notification information. That is, similar to when the situation estimation unit 52 generates the notification information, the notification information is transmitted to the terminal 20 worn by the user to whom the notification information should be transmitted. When the physical condition determination unit 53 generates the notification information, the notification information may be transmitted to a facility employee. This allows the facility employee to quickly recognize that a user has become ill.

[0048] <Chat generation unit 54> The chat generation unit 54 generates a chat room that can be used by two or more users belonging to the same group among multiple users of the facility. That is, in the example shown in Fig. 4, the chat generation unit 54 generates a chat room corresponding to a group ID of "G001". The chat room corresponding to the group ID of "G001" is set so that only the terminal 20 to which the group ID of "G001" is set can view and post to the chat room.

[0049] When one of the multiple terminals 20 having the same group ID posted information via the input unit 26, posted information corresponding to the posted content is transmitted to the management device 40 via the power transmission device 30. In detail, in the management device 40, the third communication unit 41 receives the posted information. Then, the third communication unit 41 transmits the received posted information to other terminals 20 having the same group ID as the one terminal 20 via the multiple power transmission devices 30. In this way, when the third communication unit 41 receives posted information from a terminal 20, it transmits the posted information to terminals 20 corresponding to other users who belong to the same group as the user corresponding to the terminal 20.

[0050] As a result, the information posted on the one terminal 20 is displayed on the display unit 25 of the other terminals 20 to which the same group ID as the one terminal 20 is set. In other words, a plurality of users who use the facility as a group can communicate in the chat room corresponding to the group ID. Note that the information posted in the chat room may be text information, fixed phrases, pictograms, stamps, etc.

[0051] <Additional information generating unit 55> The additional information generation unit 55 generates additional information to be notified to a specific user. The additional information is, for example, coupon information and promotional information for the user, which is generated based on personal information including the user's facility usage history. The additional information is also facility usage plan information, which is generated based on personal information including the user's age, physical condition, and mood. As an example, the usage plan may specify the duration and order of stay in multiple areas AR, and specifically, the duration and interval of use of the sauna room. The additional information, like the notification information, is transmitted by the third communication unit 41 to the terminal 20 worn by the user to whom the additional information is to be transmitted.

[0052] <Display control unit 56> The display control unit 56 controls the display device 60. Specifically, the display control unit 56 causes the display device 60 to display the user density in a plurality of areas AR. The display control unit 56 may cause the display device 60 to display the user density calculated by the situation estimation unit 52 itself, or may cause the display device 60 to display a usage status according to the user density.

[0053] <Display device 60> The display device 60 is, for example, a large monitor. The display device 60 may be installed at the reception desk of the facility or in a rest area of ​​the facility. The display device 60 is preferably installed in a position that is easily visible to users of the facility.

[0054] <Operation of this embodiment> When a user uses a facility, the user first puts on the terminal 20 loaned to them by the facility. At this time, the management device 40 associates the user with the terminal 20 loaned to the user using a user ID and a terminal ID, as shown in Fig. 4. Furthermore, when the user uses the facility in a group with other users, a group ID is set for the user.

[0055] Multiple users using the facility stay in a desired area AR among multiple areas AR. For this reason, as shown in Figure 1, there are areas AR where users are concentrated, such as the fourth area AR4, and areas AR where users are not concentrated, such as the second area AR2. In addition, the number of users using the facility increases or decreases depending on the day of the week and the time of day.

[0056] In this regard, the usage status management system 10 calculates the user density in multiple areas AR based on user location information transmitted from the terminal 20. Furthermore, the usage status management system 10 displays the user density for each area AR on the display device 60 and the facility's website. This allows users currently using the facility to move to an area AR with a lower user density. Furthermore, users who are about to use the facility can take measures such as changing the time of day they use the facility.

[0057] <Effects of this embodiment> (1) The usage status management system 10 estimates the density of users based on the location information of multiple terminals 20. Therefore, the usage status management system 10 can grasp the usage status of users within the facility without requiring confirmation work by facility employees. Therefore, the usage status management system 10 can reduce the burden on facility employees.

[0058] (2) The usage status management system 10 estimates the density of users for each of multiple areas AR. As a result, the usage status management system 10 can inform users that an area AR in a facility is less crowded than other areas AR, or can encourage users who are staying in a crowded area AR to move to a less crowded area AR.

[0059] (3) The usage status management system 10 can determine changes in the user's physical condition based on the vital sign information transmitted from the terminal 20. Therefore, the usage status management system 10 can give a sense of security to users who use the facility.

[0060] (4) The usage status management system 10 can display notification information encouraging movement on the display units 25 of the terminals 20 worn by users who are crowded together within a certain area AR. Furthermore, the usage status management system 10 can display notification information encouraging movement on the display units 20 of the terminals 20 worn by users who have not moved within a certain area AR for a long period of time. In this way, the usage status management system 10 can eliminate imbalances in the usage status of facilities by users.

[0061] (5) The usage status management system 10 generates chat rooms that can be used by multiple users who use the facility as a group. This allows two or more users who belong to the same group to communicate with each other when they are apart within the facility, for example, when the facility is divided into separate men's and women's baths. Therefore, the usage status management system 10 can increase convenience for users who use the facility.

[0062] (6) The usage status management system 10 transmits additional information to the user regarding the user's use of the facility, allowing the user to make plans for after using the facility while using the facility and to use the facility more appropriately.

[0063] (7) Because the terminal 20 is charged by microwave power supply, there is no need to provide a charging terminal or a cover for battery replacement on the terminal 20. This improves the water resistance of the terminal 20. Also, there is no need to worry about the terminal 20 running out of battery, and the hassle of battery replacement is eliminated. Furthermore, because power can be supplied to the terminal 20 at all times, the terminal 20 can transmit a beacon signal with high strength. As a result, the accuracy of the location information of the terminal 20 is improved.

[0064] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0065] The usage status management system 10 can be used in facilities other than bathing facilities. For example, the usage status management system 10 may be used in a sports gym, a theme park, or an event such as a live concert.

[0066] The usage status management system 10 can be used in a facility that has only one area AR. In this case, the usage status management system 10 only needs to include multiple terminals 20, one power transmission device 30, and one management device 40.

[0067] The usage status management system 10 can omit functions related to group chat. The usage status management system 10 can also omit functions related to the transmission of notification information and additional information to users. Furthermore, the usage status management system 10 can omit functions related to determining the user's physical condition.

[0068] The method for calculating the user density in the above embodiment is an example. The situation estimation unit 52 may calculate the user density using other methods. The shape of the terminal 20 can be changed as appropriate as long as it can be worn by the user. For example, the terminal 20 may be shaped so that it can be worn around the neck, or may be ring-shaped.

[0069] The terminal 20 may be configured to be able to communicate with the management device 40 without going through the power transmission device 30. In this case, it is preferable that the terminal 20 and the management device 40 be able to communicate wirelessly.

[0070] The phrase "at least one" as used herein means "one or more" of the desired options. As an example, the phrase "at least one" as used herein means "only one option" or "both of two options" when the number of options is two. As another example, the phrase "at least one" as used herein means "only one option" or "any combination of two or more options" when the number of options is three or more.

[0071] The first control unit 27, the second control unit 33, and the control device 42 are not limited to processing circuits equipped with a CPU and ROM and executing software processing. For example, the first control unit 27, the second control unit 33, and the control device 42 may be equipped with dedicated hardware circuits that execute at least some of the various processes executed in the above-described embodiment. An example of a dedicated hardware circuit is an ASIC. ASIC is an abbreviation for "Application Specific Integrated Circuit." In other words, the first control unit 27, the second control unit 33, and the control device 42 may have any of the following configurations (a) to (c):

[0072] (a) A processing circuit comprising a processing device that executes all of the above processes according to a program, and a program storage device such as a ROM that stores the program. (b) A processing circuit comprising a processing device and a program storage device that execute part of the above processing according to a program, and a dedicated hardware circuit that executes the remaining processing.
