[Embodiment]
(Control system)
Hereinafter, a control system according to the embodiment will be described. As shown in FIG. 1, the control system includes a facility 100, a facility management apparatus 200, and a network 300.

  The facility 100 is a facility such as a wooden house, a reinforcing steel house, a detached house, an apartment house, and a building. The facility 100 includes one or more devices 110 (devices 111 to 114) and an EMS (Energy Management System) 120. The device 110 is an air conditioning device, an AV (Audio Visual) device, a lighting device, or the like. The EMS 120 controls the equipment 110 provided in the facility 100. The EMS 120 communicates with the facility management apparatus 200 via the network 300. Communication may be performed wirelessly or may be performed by wire.

  In FIG. 1, a facility 100A and a facility 100B are illustrated as the facility 100. The facility 100A and the facility 100B have the same configuration. However, the facility 100A may be a detached wooden house, and the facility 100B may be a building.

  The facility management apparatus 200 has a function of learning a control parameter for controlling a target device that is one of the one or more devices 110, and transmits the control parameter to the facility 100 as a learning result.

(EMS)
Hereinafter, the EMS 120 according to the embodiment will be described. As illustrated in FIG. 2, the EMS 120 includes a communication unit 121 and a control unit 122.

  The communication unit 121 includes a communication module and the like, and communicates with the facility management apparatus 200 via the network 300. For example, the communication unit 121 transmits the control parameter of the device 110 associated with the facility type to the facility management apparatus 200. Similarly, the communication unit 121 transmits the control parameter of the device 110 associated with the user type to the facility management apparatus 200.

  The control unit 122 includes a CPU and a memory, and controls the EMS 121. In the embodiment, the control unit 122 configures a first specifying unit that specifies a first control parameter of a target device that matches the target facility from a facility DB 210 described later. The control part 122 comprises the 2nd specific | specification part which specifies the 2nd control parameter of the object apparatus suitable for an object user from user DB220 mentioned later. The control unit 122 synthesizes the first control parameter and the second control parameter based on the first weight value applied to the first control parameter and the second weight value applied to the second control parameter. A control unit that calculates a third control parameter suitable for the target user in the facility is configured.

  The synthesis method of the first control parameter and the second control parameter is not particularly limited. For example, when the target device is an air conditioner and the control parameter is a set temperature, the weighted average value of the first control parameter and the second control parameter may be calculated as the third control parameter. Alternatively, when the target device is an AV device and the control parameter is the display image quality setting, if the weighted average value cannot be calculated, one of the first control parameter and the second control parameter is set as the third control parameter. It may be calculated. In such a case, one of the first weight value and the second weight value may be regarded as zero.

  In the embodiment, the first weight value and the second weight value may be different depending on the type of the target device. For example, when the target device is an air conditioner, the influence of the facility type is greater than the user type, so the first weight value may be greater than the second weight value. Alternatively, when the target device is an AV device, since the influence of the user type is greater than the facility type, the second weight value may be larger than the first weight value.

  Hereinafter, a case where the user a uses the facility 100A (first type facility) and the user b uses the facility 100B (second type facility) will be described as an example. In such a case, the control parameter obtained by learning the result of the user a using the target device in the facility 100A is not only stored in the user DB 220 described later as a control parameter depending on the user a, It is stored in the facility DB 120 described later as a control parameter depending on the facility 100A. Similarly, the control parameter obtained by learning the result of the user b using the target device in the facility 100B is not only stored in the user DB 220 described later as a control parameter depending on the user b, but also stored in the facility 100B. It is stored in the facility DB 120 described later as a dependent control parameter.

  In this case, consider a case where the target user is the user a and the target facility is a facility 100B used by another user (user b) different from the target user. That is, consider a case where the facility used by the user a changes from the facility 100A to the facility 100B. In such a case, the control unit 122 uses the user b in the facility 100B in addition to the control parameter (second control parameter depending on the user a) obtained by learning the result used by the user a in the facility 100A. Based on the control parameter (first control parameter depending on the facility 100B) obtained by learning the result, the third control parameter is calculated. According to such a configuration, since the target device is controlled by the third control parameter including the first control parameter depending on the facility type, the target device is appropriately selected even if the facility used by the user a is changed. Can be controlled.

  Here, in order to simplify the description, a case where another user different from the target user is the user b is illustrated. However, other users different from the target user may be a plurality of users or may include users of the same user type as the user a.

(Facility management device)

  The facility DB 210 is configured by an HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like, and is a DB (Data Base) that stores control parameters of the target device for each type of facility 100 (hereinafter, facility type). is there. For example, as illustrated in FIG. 4, the facility DB 210 includes, for each facility type (here, facility type B), identification information (here, device ID) for identifying the device 110 and a first for controlling the device 110. Stores information that associates control parameters. The facility DB 210 stores information shown in FIG. 4 for each facility type.

  In the embodiment, the facility DB 210 learns the control result of the device 110 in the facility 100 of the corresponding facility type without distinguishing the user, and learns as the first control parameter of the device 110 in the facility 100 of the corresponding facility type. Store the result.

  Here, the facility type may be classified according to at least one of structure, floor plan, ventilation condition, heat insulation condition, soundproof condition, noise condition, sunshine condition, climatic condition, and power rate. The structure is a parameter indicating the structure of the facility 100 (a wooden house, a reinforced house, a detached house, an apartment house, etc.). The floor plan is a parameter indicating the arrangement, size, usage, and the like of the room that the facility 100 has. The ventilation condition is a parameter relating to ventilation of the facility 100, and is a parameter indicating, for example, the layout of windows, the size of windows, and the capacity of ventilation equipment. The heat insulation condition is a parameter relating to heat insulation of the facility 100, and includes, for example, a wall structure, a wall thickness, a window structure, the number of windows, and a window size. The soundproofing condition is a parameter related to soundproofing that the facility 100 has, such as a wall structure, a wall thickness, a window structure, the number of windows, and a window size. The noise condition is a parameter relating to noise included in the facility 100, for example, a parameter indicating the presence or absence of a noise source around the facility 100. The sunshine condition is a parameter related to the sunshine that the facility 100 has, for example, a parameter that indicates the amount of sunshine for each season and time. The climatic conditions are parameters relating to the climate of the area where the facility 100 is provided, and are parameters indicating, for example, average temperature, average humidity, and average precipitation. The electricity charge is a parameter related to a contract between the facility 100 and the power company, and is a parameter indicating an incentive to comply with, for example, a power purchase charge, a power sale charge, and DR (Demand Response).

  As described above, there are various parameters for classifying the facility type. The structure, floor plan, ventilation condition, heat insulation condition, soundproof condition, noise condition, sunshine condition, climatic condition, and electricity rate overlap each other. Parameters may be included.

  The user DB 220 is configured by an HDD, an SSD, or the like, and is a DB (Data Base) that stores control parameters of the target device for each user type (hereinafter, user type). For example, as illustrated in FIG. 5, the user DB 220 includes, for each user type (here, user type a), identification information (here, a device ID) for identifying the device 110 and second information for controlling the device 110. Stores information that associates control parameters. The user DB 220 stores information shown in FIG. 5 for each user type.

  In the embodiment, the user DB 220 learns the control result of the device 110 by the user of the corresponding user type without distinguishing the facility 100, and the learning result as the second control parameter of the device 110 by the user of the corresponding user type. Is stored.

  Here, the user type is classified by at least one of user identification information, gender, age, voice information, appearance characteristics, life patterns, and economic ideas. The user identification information is a parameter for identifying a user, such as an ID assigned to each user. The gender is a parameter indicating gender. The voice information is similar to the user identification information and is a parameter such as a voiceprint for identifying the user. The appearance feature is a parameter related to the user's appearance, for example, a parameter indicating height and weight. The life pattern is a parameter related to the user's life and is a parameter indicating a night type, a morning type, or the like. The economic concept is a parameter relating to a balance between quality of life (QoL) and costs such as electricity charges, and is a parameter indicating, for example, QoL priority or cost priority.

  The communication unit 230 includes a communication module and the like, and communicates with the facility 100 via the network 300. The communication unit 230 receives the control parameter of the device 110 associated with the facility type from the facility 100. Such control parameters are used for learning the first control parameter stored in the facility DB 210 described above. Similarly, the communication unit 230 receives the control parameter of the device 110 associated with the user type from the facility 100. Such a control parameter is used for learning the second control parameter stored in the user DB 220 described above.

  The control unit 240 includes a CPU and a memory, and controls the facility management apparatus 200. Although not particularly limited, the control unit 240, like the control unit 122, combines the first control parameter and the second control parameter based on the first weight value and the second weight value. In the target facility, it may have a function of calculating a third control parameter suitable for the target user. In such a case, the control unit 240 instructs the communication unit 240 to transmit the third control parameter to the facility 100.

(Control method)
Hereinafter, a control method according to the embodiment will be described.

  First, control of the target device will be described with reference to FIG.

  As shown in FIG. 6, in step S10, the EMS 120 specifies the facility type of the facility 100 (target facility) where the EMS 120 is provided. Although the method of specifying the facility type is not particularly limited, the facility type may be specified by receiving the facility type from a terminal possessed by the target user, and may be performed by pre-registering the facility type with the EMS 120. It may be broken.

  In step S11, the EMS 120 transmits information identifying the facility type to the facility management apparatus 200, and specifies the first control parameter of the target device that matches the target facility from the facility DB 210.

  In step S12, the EMS 120 specifies a user type of a user (target user) existing in the facility 100 where the EMS 120 is provided. The user type identification method is not particularly limited, but the user type identification may be performed by receiving the user type from a terminal possessed by the target user, or by image recognition of the target user. May be.

  In step S13, the EMS 120 transmits information for identifying the user type to the facility management apparatus 200, and specifies the second control parameter of the target device that matches the target user from the user DB 220.

  In step S14, the EMS 120 calculates the third control parameter suitable for the target user in the target facility by combining the first control parameter and the second control parameter based on the first weight value and the second weight value. To do.

  In step S15, the EMS 120 controls the target device according to the third control parameter.

  Here, in FIG. 6, step S11 and step S13 are separate processes, but these processes may be performed simultaneously. That is, the EMS 120 may specify a first control parameter and a second control parameter by transmitting a message including both information identifying the facility type and information identifying the user type to the facility management apparatus 200. Such a message may be considered as a message requesting acquisition of the first control parameter and the second control parameter.

  Secondly, learning of the first control parameter and the second control parameter will be described with reference to FIG.

  In step S20, the target user changes the setting of the target device in the target facility. The facility management apparatus 200 receives the control parameter related to the changed setting from the facility 100.

  In step S21, the facility management apparatus 200 updates the first control parameter stored in the facility DB 210 based on the control parameter received in step S20. In other words, the first control parameter relating to the same facility type as the target facility is updated regardless of the target user.

  In step S22, the facility management apparatus 200 updates the second control parameter stored in the user DB 220 based on the control parameter received in step S20. In other words, regardless of the target facility, the second control parameter relating to the same user type as the target user is updated.

(Function and effect)
In the embodiment, the first control parameter depending on the facility type and the second control parameter depending on the user type are stored in the facility DB 210 and the user DB 220. The EMS 120 calculates a third control parameter suitable for the target user in the target facility by combining the first control parameter and the second control parameter based on the first weight value and the second weight value. Therefore, even if the facility used by the target user changes, the target device can be appropriately controlled.

  In particular, in the initial setting after the facility used by the target user is changed, it is unclear whether the second control parameter depending on the user type is useful in the target facility. Therefore, the above-described configuration is useful when used in the initial setting after the facility used by the target user is changed.

[Modification 1]
Hereinafter, Modification Example 1 of the embodiment will be described. In the following, differences from the embodiment will be described.

  In the first modification, the user type is classified by a combination of two or more users. For example, a combination of two or more users is a family structure or the like. According to such a configuration, even in a case where two or more users share one facility, the target device can be appropriately controlled.

[Modification 2]
Hereinafter, a second modification of the embodiment will be described. In the following, differences from the embodiment will be described.

  In the second modification, when the target user is two or more users, the priority of two or more users is determined. The EMS 120 adapts to the target user by weighting and combining the second control parameter associated with the user type of the user with high priority and the second control parameter associated with the user type of the user with low priority. The second control parameter may be specified. In such a case, the weight value applied to the second control parameter associated with the user type of the user with the higher priority is set to the second control parameter associated with the user type of the user with the lower priority. Greater than the applied weight value.

  Note that the EMS 120 may identify the second control parameter associated with the user type of the user with high priority from the user DB 220. In such a case, the weight value applied to the second control parameter associated with the user type of the user with low priority is zero.

  In the following, priority update will be described. For example, let us consider a case where the setting of the target device is changed when the user X and the user Y exist. In such a case, the EMS 120 determines which of the control parameters suitable for the user X and the user Y is the control parameter after the setting is changed. The EMS 120 relatively increases the priority of the user X if the control parameter after the setting is changed is close to the control parameter suitable for the user X. Furthermore, the second control parameter associated with the user type of the user X may be updated by learning the control parameter after the setting is changed. Similarly, the EMS 120 relatively increases the priority of the user Y if the control parameter after the setting is changed is close to the control parameter suitable for the user Y. Furthermore, the second control parameter associated with the user type of the user Y may be updated by learning the control parameter after the setting is changed.
