DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments.

[0018] <Configuration of environmental control system> 1 shows an example of the configuration of an environmental control system according to an embodiment of the present invention. The environmental control system 1 includes a plurality of environmental devices (10, 20, 30, 40) installed at predetermined positions in a predetermined area BD within a building, a wireless tag 60 that transmits wireless signals including unique identification information, a mobile terminal associated with the wireless tag 60 and transmitting environmental request information related to the environment of the predetermined area within the building, a base station 50 installed at a predetermined position in the predetermined area BD within the building and receiving the wireless signal from the wireless tag 60, and an environmental control device 100 that is connected to the plurality of environmental devices (10, 20, 30, 40), the base station 50, and the mobile terminal 70 via a network and controls the environment of the predetermined area BD within the building by controlling at least one of the plurality of environmental devices (10, 20, 30, 40).

[0019] In the configuration example of Fig. 1, areas BD of two buildings are each equipped with a plurality of air conditioning devices 10, lighting devices 20, blind devices 30, ventilation devices 40, and base stations 50. A user 2 within the area has a mobile terminal 70, which he or she uses to transmit environmental request information to the environmental control device 100. A wireless tag 60 is attached to the user 2 when the user 2 enters area BD within the building, and is used to identify the user 2's location within the area by associating it with the user 2's mobile terminal 70.

[0020] The environmental control device 100 is connected to a plurality of air conditioners 10, lighting devices 20, blind devices 30, ventilation devices 40, base stations 50, and mobile terminals 70 via a network NW. The positions of the plurality of air conditioners 10, lighting devices 20, blind devices 30, ventilation devices 40, and base stations 50 are registered in advance in the environmental control device 100.

[0021] The location of the user 2 within the area is identified by receiving a wireless signal (beacon signal) containing unique identification information transmitted by the wireless tag 60. For example, the location of the wireless tag 60 within the area can be identified by at least three base stations 50 receiving the beacon signal transmitted by the wireless tag 60.

[0022] The environmental control device 100 is configured to control environmental equipment (10, 20, 30, 40) close to the location of the user 2 based on environmental request information from the user 2 received from the mobile terminal 70, thereby providing an environment that suits the location of the user 2 and the requests of the user 2.

[0023] The environmental control device 100 stores the positions (first position information) of the environmental devices (10, 20, 30, 40) within the area and the positions (second position information) of the wireless tags 60 within the area, and when it receives environmental request information from the mobile terminal 70, it identifies at least one environmental device (10, 20, 30, 40) to be controlled based on the position of the corresponding wireless tag 60, the position of the environmental device (10, 20, 30, 40), and the environmental request information, and is configured to control the identified at least one environmental device (10, 20, 30, 40) in accordance with the environmental request information.

[0024] <Environmental control in environmental control systems> FIG. 2 is a diagram illustrating environmental control in an environmental control system according to an embodiment of the present invention. In the configuration example of FIG. 2, two lighting devices 20, two air conditioners 10, and a base station 50 are installed within an area of ​​a building. A user carries a mobile terminal associated with a wireless tag. The wireless tag 60 and the mobile terminal 70 can be associated with each other by, for example, reading a QR code (registered trademark) attached to the wireless tag 60 with a camera of the mobile terminal 70. This QR code may be configured to include information about the URL of the environmental control device 100 to which environmental request information is to be sent.

[0025] When a user 2 carrying a mobile terminal 70 associated with a wireless tag 60 transmits environmental request information such as "hot" or "dark" from the mobile terminal 70, the environmental control device 100 identifies the location of the wireless tag 60 associated with the mobile terminal 70 that transmitted the environmental request information, and identifies, for example, environmental devices installed in a location close to the location of the wireless tag 60 as devices to be controlled. Here, the environmental control device 100 only needs to identify at least one environmental device as a control target. The number of environmental devices to be controlled is determined appropriately depending on the location of the user 2 and the content of the environmental request information.

[0026] 2, environmental request information related to air conditioning and lighting, such as "hot" and "dark," is received, so air conditioner #1 and lighting device #1 located close to user 2's location are identified as control targets, and air conditioning control is performed to lower the temperature and lighting control is performed to turn on the lights in response to the requests, "hot" and "dark." User 2 can receive an environment that meets their request simply by transmitting their environmental request from mobile terminal 70, without having to be aware of their location within their area, the location of the switches for the environmental devices to be controlled, or the dedicated remote controls for controlling each of the environmental devices, so an environmental control system that places little burden on the user can be provided.

[0027] FIG. 3 is a diagram illustrating the characteristics of environmental control in an environmental control system according to an embodiment of the present invention. As shown in FIG. 3, each of the environmental devices (10, 20, 30, 40) operates using dedicated software, and a dedicated control protocol is typically employed for the control signals for controlling each of the environmental devices (10, 20, 30, 40). In the environmental control according to this embodiment, a user 2 transmits environmental request information related to air conditioning and lighting using general-purpose software for browsing the Internet, such as a web browser, installed on a mobile terminal 70. The environmental control device 100 then performs protocol conversion according to the dedicated control protocol for the environmental device corresponding to each piece of environmental request information to generate a control signal. The environmental control device 100 determines the environmental device to be controlled based on the user's environmental request information, performs protocol conversion to the dedicated control protocol for controlling the determined environmental device, generates a control signal, and transmits the generated control information to the environmental device.

[0028] With this configuration, user 2 can receive an environment that corresponds to the environmental request information through a simple operation of sending the environmental request information on general-purpose software for browsing the Internet on mobile terminal 70, without having to worry about the location of the switch of the environmental device to be controlled or the dedicated remote control for controlling each environmental device, thereby providing an environmental control system that places less of a burden on the user. Even when new environmental equipment is installed, it is only necessary to set the environmental control device 100 to perform conversion processing to a dedicated protocol that corresponds to the new environmental equipment, so there is no need to install new software on the user's mobile terminal.

[0029] 3, in the environmental control of this embodiment, a device operation system that operates the environmental devices and a position measurement system that measures the position of user 2 are functionally separated, and the portable terminal 70 of user 2 is configured not to be involved in measuring the user's position. By functionally separating the device operation system and the position measurement system and configuring the software of portable terminal 70 and the wireless signals it sends and receives so as not to be used to identify position information, it is possible to prevent spoofing by outsiders and to build a highly secure system.

[0030] The functional separation of the device operation system and the position measurement system described above does not prevent devices that realize each function from being housed in the same housing, but the mobile terminal 70 that operates the device may be configured as separate hardware from the wireless tag 60. By configuring them as separate hardware, even if the method of position measurement for the wireless tag 60 is changed, there is no need to install new software on the user's mobile terminal 70 or to perform operations or send signals according to the method of position measurement, making it possible to build an environmental control system that places less of a burden on the user.

[0031] <Configuration of environmental control device> 4 shows an example of the configuration of an environmental control device in an environmental control system according to an embodiment of the present invention. Environmental control device 100 includes an environmental device control unit 101 that controls environmental devices; a location information management unit 102 that manages the locations of environmental devices, base stations, and wireless tags; an ID management unit 103 that manages user ID information and associates it with wireless tags; a memory unit 104 that stores location information for environmental devices, base stations, and wireless tags; an input unit 105 that inputs various data such as location information; a display unit 106 that displays various data such as control information for environmental devices; and an I / F unit 107 that connects to environmental devices, base stations, and mobile terminals via a network NW. Environmental control device 100 can be realized by a computer equipped with a central processing unit, memory, and interfaces.

[0032] <Identifying the location of a wireless tag> Fig. 5 is a diagram for explaining how to identify the location of a wireless tag according to an embodiment of the present invention. In the configuration example shown in Fig. 5, three base stations 50 installed in an area BD of a building receive beacon signals transmitted by a wireless tag 60, and the location of the wireless tag 60 within the area BD can be identified based on the signal strength of the beacon signals received by the three base stations 50 and the location information of the base stations 50.

[0033] The method for identifying the location of the wireless tag 60 is not limited to the above-described method, and other methods can be used. For example, the location of the wireless tag 60 may be identified by activating the wireless tag 60 based on wireless signals transmitted from multiple base stations 50 installed at predetermined locations, and having a specific base station 50 receive the beacon signal transmitted by the wireless tag 60. Alternatively, multiple wireless transmitters with narrow wireless signal transmission areas may be installed, and the wireless tag 60 may be activated by the wireless signals transmitted from the wireless transmitters. The beacon signal transmitted from the activated wireless tag may be received by a specific base station 50, and the location of the wireless tag 60 may be identified using the location information of the wireless transmitters.

[0034] <Identifying environmental equipment based on control area> The environmental devices (10, 20, 30, 40) to be controlled may be identified based on their installation positions within the area in which they are installed, but if multiple environmental devices correspond to one control area, the environmental devices to be controlled may be identified based on information indicating the position of the control area of ​​the environmental devices (representative position of the control area).

[0035] Fig. 6 is a diagram illustrating control of lighting devices 20 according to an embodiment of the present invention. In the example of Fig. 6, four lighting devices 20 are installed in an area BD of a building, which is configured with one control area CA#1 controlled by two lighting devices 20 and two control areas CA#2 and CA#3 controlled by one lighting device 20.

[0036] When a user 2 carrying a wireless tag 60 is present at a certain position within area BD of the building shown in FIG. 6, the position (X1, Y1) (representative position of the control area) indicating control area CA#1 of two lighting devices 20 out of the three control areas CA#1-#3 is close to the position (X4, Y4) of the wireless tag, and therefore the two lighting devices 20 in control area CA#1 are identified as the control targets.

[0037] Fig. 7 is a diagram for explaining the control of air conditioners according to an embodiment of the present invention. In the case of air conditioners 10, as in the case of lighting device 20 in Fig. 6, the position (X1, Y1) (control area representative position) indicating control area CA#1 of two air conditioners 10 out of three control areas CA#1-#3 is close to the position (X4, Y4) of the wireless tag 60, so the two air conditioners 10 in control area CA#1 are identified as control targets.

[0038] <Base station location management data> FIG. 8 shows an example of location management data for a base station according to an embodiment of the present invention. The location management data shown in FIG. 8 registers location information for each base station 50 installed in each area of ​​a building. The location of the wireless tag 60 is identified using the location information for this base station 50 and strength information for the beacon signal received by the base station 50. The location information for this base station 50 is sufficient as long as it can identify the relative positional relationship between the environmental device, the base station, and the wireless tag, and does not necessarily have to be absolute location information such as latitude / longitude. The same applies to FIGS. 9 and 10. On the other hand, when environmental devices in multiple building areas are to be controlled collectively, the locations of the environmental devices, etc. may be managed using absolute location information such as latitude / longitude.

[0039] <Location management data for environmental equipment> Fig. 9 is an example of location management data for environmental devices according to an embodiment of the present invention. The location management data shown in Fig. 9 registers the device type and location information for each environmental device installed in each area of ​​a building. This location information may register the location where the environmental device is installed, or, if multiple environmental devices correspond to one control area CA, information indicating the location of the control area of ​​the environmental device (control area representative location) may be registered. If information indicating the location of the control area of ​​the environmental devices is registered, multiple environmental devices corresponding to that control area are identified as control targets.

[0040] <Location management data for users and wireless tags> Fig. 10 shows an example of location management data for users and wireless tags according to an embodiment of the present invention. In the location management data shown in Fig. 10, the tag ID of the associated wireless tag and the location information of the wireless tag 60 are registered for each user ID. The location information of the wireless tag 60 identified using the location information of the base station 50 in Fig. 8 is registered for each user ID / tag ID in Fig. 10, the location of the corresponding mobile terminal 70 is identified using the location information of the wireless tag 60, and the environmental equipment to be controlled is identified based on that location.

[0041] <Environmental control sequence> 11 is a diagram showing an example of an operation sequence of an environmental control method according to an embodiment of the present invention. A user 2 who uses a predetermined area of ​​a building is given a wireless tag 60 for identifying his / her location within the area. The environmental control device 100 has registered therein the location information of the base station 50 shown in FIG. 8 and the location information of the environmental devices shown in FIG. 9.

[0042] The user 2 to whom the wireless tag 60 is assigned associates the assigned wireless tag 60 with the mobile terminal 70, and transmits ID information in which the user ID and the wireless tag ID are associated to the environment control device 100. The association between the wireless tag 60 and the mobile terminal 70 can be performed, for example, by reading a QR code or the like attached to the wireless tag 60 with the camera of the mobile terminal 70. This QR code may be configured to include information on the URL of the environment control device 100. Information on the user ID and tag ID is transmitted to the environment control device 100, and is registered in a state in which the user ID and tag ID are associated with each other, as shown in FIG. 10 . However, at this stage, the location information of the wireless tag 60 has not been registered.

[0043] When a wireless tag 60 within a predetermined area of ​​the building transmits a beacon signal, a base station 50 installed within the predetermined area of ​​the building receives the beacon signal transmitted by the wireless tag 60 and transmits beacon information including strength information of the received beacon signal to the environmental control device 100. The beacon signal includes tag ID information for identifying the wireless tag 60, making it possible to identify which wireless tag 60 transmitted the beacon information.

[0044] The environmental control device 100 identifies the location of the wireless tag 60 using the intensity information included in the received beacon information and the location information of the base station 50 registered in Fig. 8. The identified location information of the wireless tag 60 is registered in the location information data in Fig. 10. In Fig. 10, the user ID and tag ID are registered in association with each other, so the location information of the tag ID can be identified as the location information of the associated user 2.

[0045] When a user 2 inputs an environmental request into a mobile terminal 70 within a specified area of ​​the building, the input request information is transmitted to the environmental control device 100 as environmental request information. The environmental control device 100, which has received the environmental request information, uses the location information in Fig. 10 to identify the location of the wireless tag 60 associated with the mobile terminal 70 that transmitted the environmental request information, and then identifies an environmental device to be controlled using the environmental request information and the location information in Fig. 9. The environmental control device 100 controls the identified environmental device by transmitting a control signal to the environmental device according to the user's request.

[0046] The environmental control device 100 may be configured to feed back the results of the environmental control to the user 2. The content of the feedback may include, but is not limited to, control details such as "The temperature has been increased by 2 degrees" or "The temperature is at maximum," or recommendation information such as "Please open a window" or "Please move to another room." By feeding back the results of the environmental control to the user 2, there is an advantage in that, for example, the transmission of environmental request information by the user 2 can be suppressed.

[0047] <Environmental control flow> Fig. 12 is a diagram showing an example of an operational flow of the environmental control method according to the embodiment of the present invention. The location information of the base station 50 shown in Fig. 8 and the location information of the environmental equipment shown in Fig. 9 are registered in the environmental control device 100 (steps S1-1 and S1-2).

[0048] The environmental control device 100 receives ID information including the user ID and wireless tag ID transmitted from the mobile terminal 70 (step S1-3), and registers the ID information in a state in which the user ID and tag ID are associated with each other, as shown in FIG. 10 (step S1-4).

[0049] The environmental control device 100 receives beacon information including strength information of the beacon signal transmitted by the wireless tag 60 from the base station 50 installed within a specified area of ​​the building (step S1-5), and calculates the position of the wireless tag using the strength information included in the received beacon information and the pre-registered position information of the base station 50 (step S1-6), and registers it in the position information data of Figure 10 (step S1-7).

[0050] The environmental control device 100 receives environmental request information input by the user 2 in a predetermined area of ​​the building (step S1-8). After receiving the environmental request information, the environmental control device 100 uses the location information in FIG. 10 to identify the location of the user 2 who sent the environmental request information (step S1-9), and then uses the environmental request information and the location information in FIG. 9 to identify the environmental equipment to be controlled (step S1-10). The environmental control device 100 controls the identified environmental equipment in accordance with the user's request (step S1-11). The environmental control device 100 may provide feedback on the results of the environmental control to the user 2 (step S1-12).
