MODE FOR CARRYING OUT THE INVENTION

[0012] The embodiments of this disclosure will be described below with reference to the drawings. The embodiments described below are all specific examples of this disclosure. Therefore, the numerical values, shapes, materials, components, arrangement and connection configurations of components, as well as the processes (steps) and their order, shown in the following embodiments are examples and are not intended to limit this disclosure. Accordingly, any components in the following embodiments that are not described in the independent claims of this disclosure will be described as optional components.

[0013] Please note that each figure is a schematic diagram and not necessarily a strictly accurate representation. Furthermore, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations may be omitted or simplified.

[0014] (Embodiment) [composition] First, the configuration of the communication system according to the embodiment will be described. Figure 1 is a block diagram showing the configuration of the communication system 10 according to the embodiment. As shown in Figure 1, the communication system 10 comprises a plurality of lighting fixtures 20 and a control device 30. In Figure 1, an example is shown in which the communication system 10 comprises a plurality of lighting fixtures 20 and a control device 30, but the plurality of lighting fixtures 20 is an example of a plurality of controlled devices 20. For example, the communication system 10 may be equipped with a plurality of other devices such as a plurality of sensors or a plurality of schedulers instead of a plurality of lighting fixtures 20. In this embodiment, the case in which a plurality of lighting fixtures 20 is used as an example of a plurality of controlled devices 20 will be described.

[0015] In the communication system 10, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 constitute a wireless mesh network (hereinafter also simply referred to as a mesh network). A wireless mesh network is an example of a wireless communication network.

[0016] Figure 2 is a conceptual diagram of a mesh network. In Figure 2, each circle corresponds to a lighting fixture 20 (in other words, a communication node). In a mesh network, when information is transmitted from one communication node to another, the information is transmitted, for example, by a routing method, but it may also be transmitted by other methods such as a flooding method.

[0017] The information transmitted through the mesh network may include, for example, control information for controlling the lighting fixture 20 to turn on, turn off, or dim, or setting information that the control device 30 sets for the lighting fixture 20 (e.g., control group settings, control scenes, wireless settings, etc.). In addition, if the mesh network includes environmental sensors, as described later, the measured values ​​(sensing information) of the environmental sensors may also be transmitted.

[0018] Returning to the explanation in Figure 1, let's first describe the lighting fixture 20. The lighting fixture 20 is a base light, etc., installed on the ceiling of an indoor space to illuminate the space. As described above, each of the multiple lighting fixtures 20 has a wireless communication function, and the multiple lighting fixtures 20 form a mesh network. The form of the lighting fixture 20 is not particularly limited and may be a ceiling light, downlight, spotlight, etc. Specifically, the lighting fixture 20 comprises a wireless communication unit 21, a light source 22, and a storage unit 23.

[0019] The wireless communication unit 21 is a processing unit that performs wireless communication (more specifically, radio wave communication) for the lighting fixture 20 to communicate wirelessly with other lighting fixtures 20 and control equipment 30, and is, for example, a wireless communication circuit. After the lighting fixture 20 joins the mesh network, the wireless communication unit 21 performs communication through the mesh network as described above. Before the lighting fixture 20 joins the mesh network, the wireless communication unit 21 periodically transmits beacon signals (sometimes called advertisement signals, etc.) and performs individual wireless communication with control equipment 30 that receive the beacon signals. Specifically, the wireless communication unit 21 performs wireless communication according to communication standards such as BLE (Bluetooth® Low Energy) or Bluetooth® mesh.

[0020] The light source 22 emits white light into the room so that the lighting fixture 20 can illuminate the room. The light source 22 is implemented by, for example, an LED (Light Emitting Diode) element, but may also be implemented by other light-emitting elements such as a semiconductor laser, organic EL (Electro-Luminescence), or inorganic EL.

[0021] The memory unit 23 is a storage device that stores various information necessary for the operation of the lighting fixture 20, such as the setting information described later. The memory unit 23 is implemented, for example, by a semiconductor memory.

[0022] Next, the configuration of the control device 30 will be described. The control device 30 is an information terminal used by the user to configure settings related to the mesh network (initial setup and setting changes) and to control multiple lighting fixtures 20. The control device 30 is, for example, a mobile terminal such as a smartphone, tablet, or PDA (Personal Digital Assistant). The control device 30 may also be a dedicated remote controller used in the communication system 10. Specifically, the control device 30 comprises an operation reception unit 31, a display unit 32, a wireless communication unit 33, an information processing unit 34, and a storage unit 35.

[0023] The operation reception unit 31 receives user input. Specifically, the operation reception unit 31 is implemented by a touch panel or the like.

[0024] The display unit 32 displays various images. The display unit 32 is implemented by a display panel such as a liquid crystal panel or an organic EL panel.

[0025] The wireless communication unit 33 is a processing unit that performs wireless communication (more specifically, radio wave communication) for the control device 30 to communicate wirelessly with each of the multiple lighting fixtures 20, and is, for example, a wireless communication circuit. Specifically, the wireless communication unit 33 performs wireless communication in accordance with communication standards such as BLE.

[0026] The wireless communication unit 33 has multiple receiving antennas (antenna arrays) 331. The wireless communication unit 33 uses the multiple receiving antennas 331 to receive wireless signals (hereinafter also referred to as first wireless signals) transmitted from each of the multiple lighting fixtures 20. The wireless communication unit 33 also transmits wireless signals (hereinafter also referred to as second wireless signals) to the lighting fixtures 20 to control the lighting state of the lighting fixtures 20.

[0027] The information processing unit 34 causes the wireless communication unit 33 to transmit a wireless signal in response to user operations received by the operation reception unit 31. The information processing unit 34 is implemented, for example, by a microcomputer, but may also be implemented by a processor or dedicated circuit. The functions of the information processing unit 34 are realized by the execution of computer programs (software) stored in the storage unit 35 by the hardware, such as the microcomputer or processor that constitutes the information processing unit 34.

[0028] The memory unit 35 is a storage device that stores information necessary for information processing, such as computer programs executed by the information processing unit 34. The memory unit 35 is implemented, for example, by semiconductor memory. The computer programs stored in the memory unit 35 include dedicated application programs (also referred to as dedicated apps) for operating the control device 30 as either a setting terminal or a control terminal.

[0029] [Initial setup operation related to the comparative example] The control device 30 can build a mesh network by performing an initial setup operation. The initial setup operation will now be described. Figure 3 is a flowchart showing an overview of the initial setup operation. As shown in Figure 3, the initial setup operation includes a detection phase S10, a configuration phase S20, and an identification and registration phase S30 in that order. The specific processes performed in each phase will be described below with reference to the sequence diagrams. Figures 4A and 4B are sequence diagrams of the initial setup operation related to a comparative example. The initial setup operation shown in Figures 4A and 4B is performed, for example, after multiple lighting fixtures 20 have been installed on the ceiling by the installer.

[0030] First, let's explain the process performed in the detection phase S10. The operation reception unit 31 of the control device 30 receives a start operation from the user to instruct the start of the initial setup operation (S101). Figure 5 is a diagram showing an example of the initial setup screen displayed on the display unit 32 of the control device 30 in step S101 of Figure 4A. As shown in Figure 5, the initial setup screen displays a device registration icon 321 that accepts an instruction from the user to start the initial setup operation. In other words, by selecting the device registration icon 321 on the display screen in Figure 5, the operation reception unit 31 receives a start operation from the user.

[0031] Furthermore, the display screen in Figure 5 also shows a map image 324. The map image 324 is a view from above of an area where multiple lighting fixtures 20 are installed. In the example in Figure 5, the pre-planned installation locations of the lighting fixtures 20 are indicated by icons (hereinafter also referred to as planned installation icons). The planned installation icons are displayed on the map image 324 based on location information entered by the user. In other words, the map image 324 is an image showing the installation locations of multiple lighting fixtures 20. The map image 324 is stored in the storage unit 35 in advance. The strings such as "Temporary L001" shown on the planned installation icons are identification numbers assigned by the information processing unit 34. The same applies to Figures 6, 7A, and 7B thereafter.

[0032] Returning to the explanation in Figure 4A, each of the multiple lighting fixtures 20 periodically transmits a beacon signal (sometimes called an advertisement signal, etc.) before joining the mesh network (S102). Upon acceptance of the start operation in step S101, the wireless communication unit 33 of the control device 30 receives the beacon signal (i.e., the first wireless signal). The beacon signal emitted by each of the multiple lighting fixtures 20 contains identification information for that lighting fixture 20. The identification information is, for example, a MAC (Media Access Control) address, but it can be any identification information that can uniquely identify the lighting fixture 20.

[0033] The processes described above in steps S101 to S102 are the processes performed in the detection phase S10. Next, we will explain the processes performed in the configuration phase S20. The processes performed in the configuration phase S20 are also called provisioning processes.

[0034] The information processing unit 34 establishes a communication connection between the wireless communication unit 33 and any one of the multiple lighting fixtures 20 that are the source of the beacon signal received in step S102 (S201), and begins individual communication with the lighting fixture 20. The information processing unit 34 causes the wireless communication unit 33 to transmit setting information to the lighting fixture 20 (S202). The lighting fixture 20 receives the setting information and stores it in the storage unit 23 provided in the lighting fixture 20 (S203).

[0035] The configuration information is the information required for the lighting fixture 20 to join the mesh network. The configuration information includes the network ID of the mesh network to which the lighting fixture 20 belongs, and the address information (unicast address) of the lighting fixture 20 used for communication within the mesh network. The configuration information may also include, if necessary, a security passcode (authentication information) used for communication within the mesh network, information regarding the wireless communication frequency channel, and identification information of the control device 30 that performed the initial setup operation. Once the configuration information is stored in the storage unit 23, the lighting fixture 20 can join the mesh network.

[0036] When the lighting fixture 20 has finished storing the setting information, it sends a setting completion notification to the control device 30 (S204). When the information processing unit 34 of the control device 30 receives the setting completion notification by the wireless communication unit 33, it disconnects the communication connection with the lighting fixture 20 that it connected to in step S201 (S205).

[0037] The process from steps S201 to S205 is repeated until all lighting fixtures 20 have joined the mesh network. In other words, the information processing unit 34 of the control device 30 performs configuration processing by establishing a communication connection with each of the lighting fixtures 20 that were able to receive the beacon signal in step S102. Lighting fixtures 20 that have joined the mesh network either stop the periodic transmission of beacon signals that they were performing before joining, or continue the periodic transmission of beacon signals while increasing the transmission interval of the beacon signals.

[0038] The processes described above in steps S201 to S205 constitute the processes performed in the configuration phase S20 (also referred to as the configuration process). Next, the processes performed in the identification and registration phase S30 will be explained.

[0039] As shown in Figure 4B, the information processing unit 34 establishes a communication connection between one of the multiple lighting fixtures 20 that have joined the mesh network and the wireless communication unit 33 (S301). Note that the process in step S301 can be omitted by not terminating (maintaining) the communication connection with the lighting fixture 20 that last transmitted the setting information in the setting phase S20. Furthermore, the process in step S301 can also be omitted when the control device 30 joins the mesh network (the control device 30 itself is a communication node in the mesh network).

[0040] Next, the information processing unit 34 displays icons for the multiple lighting fixtures 20 that have joined the mesh network on the display unit 32 (S302). For example, the information processing unit 34 displays multiple icons 322 corresponding to the multiple lighting fixtures 20 in a horizontal row, as shown in the initial setup screen of Figure 6. Figure 6 is a diagram showing an example of the initial setup screen displayed on the display unit 32 of the control device 30 in step S302 of Figure 4B.

[0041] Returning to the explanation in Figure 4B, the operation reception unit 31 receives a selection operation from the user for one of the multiple icons 322 (S303). The selection operation is, for example, a tap operation on one of the multiple icons 322 on the display screen in Figure 6. The information processing unit 34 transmits a blinking command via the mesh network to the lighting fixture 20 (hereinafter also referred to as the target lighting fixture 20) corresponding to the selected icon 322 (S304). More specifically, the blinking command is transmitted from the wireless communication unit 33 of the control device 30 to the lighting fixture 20 wirelessly connected in step S301, and then transmitted to the target lighting fixture 20 via the mesh network. The blinking command is also transmitted on the display screen in Figure 6, for example, after the selection operation, triggered by the reception of a tap operation on the blinking icon 323. Note that in step S304, the blinking command that the information processing unit 34 has the wireless communication unit 33 transmit corresponds to the second wireless signal.

[0042] The flashing command is a signal to selectively flash the target lighting fixture 20. When the target lighting fixture 20 receives the flashing command, it flashes (S305). This allows the user to identify the target lighting fixture 20. Note that the flashing of the target lighting fixture 20 in step S305 corresponds to a change in the control state of the controlled device 20.

[0043] The user visually confirms the actual installation location of the flashing light fixture 20 (S306) and specifies the installation location of the flashing light fixture 20 on the map image 324 (for example, one installation icon from among multiple installation icons). The operation reception unit 31 receives the user's operation to specify the installation location of the light fixture 20 in the map image 324 (S307). Figure 7A shows an example of the initial setup screen displayed on the display unit 32 of the control device 30 before step S307 of Figure 4B is executed, and Figure 7B shows an example of the initial setup screen displayed on the display unit 32 of the control device 30 when step S307 of Figure 4B is executed.

[0044] In the display screen shown in Figure 7A, if the lighting fixture 20 that the user has visually confirmed (in the example of Figure 7A, the lighting fixture 20 corresponding to the icon 322 displayed in inverted black and white) is installed at the location of the planned installation icon with identification number "Temporary L006", for example, the user taps the planned installation icon with identification number "Temporary L006" to select it. When the operation reception unit 31 receives the tap operation from the user, the information processing unit 34 displays a display screen on the display unit 32 as shown in Figure 7B. Specifically, the information processing unit 34 displays a display screen on the display unit 32 showing a selection icon 325 near the planned installation icon. Then, when the user taps the selection icon 325 to select it, the operation reception unit 31 receives the operation to specify the installation location of the lighting fixture 20 in step S307.

[0045] Returning to the explanation in Figure 4B, upon receiving the specified operation in step S307, the information processing unit 34 associates the identification information indicated by the icon 322 selected in step S303 with the installation position (coordinates) specified in step S307 and stores (registers) it in the storage unit 35 (S308). The information processing unit 34 also removes the display of the icon 322 for which the association has been completed (S309). In other words, the number of icons 322 displayed in step S302 decreases by one.

[0046] The process from steps S303 to S309 is repeated until all icons 322 (identification information) displayed in step S302 are associated with their installation locations. As a result, the storage unit 35 stores the identification information of multiple lighting fixtures 20 and correspondence information indicating the relationship between their installation locations. In other words, multiple lighting fixtures 20 are registered with the control device 30.

[0047] The processes described above in steps S301 to S309 are the processes performed in the identification and registration phase S30.

[0048] Furthermore, in the initial setup operation described above, the setup phase S20 and the identification and registration phase S30 may be swapped. In other words, steps S301 to S309 may be executed first, followed by steps S201 to S205. In such a case, during the identification and registration phase S30, the control device 30 receives beacon signals emitted by multiple lighting fixtures 20 in advance and communicates individually with any one of the multiple lighting fixtures 20.

[0049] As explained above, the control device 30 can bring multiple lighting fixtures 20 into the mesh network by performing an initial setup operation. In other words, the control device 30 can build a mesh network.

[0050] [Initial setup operation according to the embodiment] As explained in step S306 above, the user visually checks the actual installation location of the lighting fixture 20 against its location on the map image 324. In such cases, if there are hundreds or thousands of lighting fixtures 20 installed in a large space, the user may not be able to determine the exact installation location of a flashing lighting fixture 20 because it is far away from them.

[0051] To address these challenges, in the identification and registration phase S30, when displaying multiple icons 322 corresponding to multiple lighting fixtures 20 on the display unit 32, a configuration is conceivable in which the information processing unit 34 displays information regarding the installation direction of the lighting fixtures 20 on the initial setup screen. For example, a configuration is conceivable in which the information processing unit 34 displays multiple icons 322 containing information regarding the installation direction of the lighting fixtures 20 on the initial setup screen.

[0052] More specifically, the control device 30 estimates (in other words, identifies) the installation direction of the multiple lighting fixtures 20 based on the first wireless signal received from the multiple lighting fixtures 20, and displays multiple icons 322 containing information about the estimated (in other words, identified) installation direction on the initial setup screen. The installation direction of the multiple lighting fixtures 20 indicates the approximate installation direction from the control device 30 to the multiple lighting fixtures 20. Once the installation direction is indicated, the user can prioritize flashing the lighting fixtures 20 that are considered to be nearby and whose exact installation location is easy to determine. Figure 8 is a sequence diagram showing a first example of the initial setup operation according to this embodiment. Note that Figure 8 is a sequence diagram in which the control device 30 is executed by a terminal device dedicated to the communication system 10, specifically a terminal device in which multiple receiving antennas 331 are located at specific positions.

[0053] The processing in steps S101 to S102, steps S201 to S205, and step S301 is as described above. After step S301, the information processing unit 34 displays a notification screen on the display unit 32 to specify to the user how to hold the control device 30 (S311). Figure 9 shows an example of the notification screen 326 displayed on the display unit 32 of the control device 30 in step S311 of Figure 8.

[0054] As shown in Figure 9, the information processing unit 34 may also display a notification screen 326 as a pop-up (overlaid display) for the user to specify how to hold the control device 30.

[0055] Returning to the explanation in Figure 8, the information processing unit 34 calculates the time difference when multiple receiving antennas 331 of the wireless communication unit 33 receive the first radio signal transmitted from one lighting fixture 20 (i.e., the beacon signal received in step S102) (S312). For example, the information processing unit 34 calculates the difference in timing (time difference) when multiple receiving antennas 331 receive the first radio signal according to the AoA (Angle of Arrival) method. Based on the time difference calculated in step S312, the information processing unit 34 estimates (in other words, identifies) the direction of arrival of the first radio signal and estimates (in other words, identifies) the installation direction of the lighting fixture 20, which is the source of the first radio signal (S313). Then, the information processing unit 34 displays multiple icons 322 on the display unit 32 that contain information about the installation direction of the lighting fixture 20 estimated (in other words, identified) in step S313 (S314). Figure 10 shows an example of the initial setup screen displayed on the display unit 32 of the control device 30 in step S314 of Figure 8.

[0056] As shown in Figure 10, the information processing unit 34 indicates, for example, information regarding the installation direction of the lighting fixture 20 (i.e., the installation direction of the lighting fixture 20) using marks such as arrows (i.e., symbols). In the example shown in Figure 10, the estimated installation direction of the lighting fixture 20 is indicated according to the direction of the arrow. Specifically, an icon 322 containing a symbol with an arrow pointing to the right means that the lighting fixture 20 corresponding to that icon 322 is installed to the right as viewed from the control device 30.

[0057] Note that the multiple icons 322 may contain information other than information regarding the installation direction of the lighting fixture 20. For example, the word "Dimming" shown at the top of each icon 322 indicates the type of equipment of the lighting fixture 20 (controlled equipment 20). Also, the string of characters such as "L001" shown at the bottom of each icon 322 is the identification number of the lighting fixture 20, and is a display identification number automatically assigned by the control equipment 30 for each piece of identification information of the lighting fixture 20.

[0058] The processes described above in steps S301, S311-S314, and S303-S309 are the processes performed in the identification and registration phase S30 of the initial setup operation according to this embodiment. In steps S312 and S313, the information processing unit 34 may calculate the phase difference of the first radio signal received by the multiple receiving antennas 331 and estimate the installation direction of the lighting fixture 20.

[0059] In this way, the information processing unit 34 displays multiple icons 322 on the display unit 32 that correspond to multiple lighting fixtures 20, including information about the estimated installation direction of the lighting fixtures 20. This makes it easier for the user to predict the installation position of the target lighting fixture 20 when visually inspecting the target lighting fixture 20, thereby shortening the time required for setup.

[0060] Furthermore, in step S311, the control device 30 can reduce the influence of how the control device 30 is held by displaying a notification screen 326 on the display unit 32 for the user to specify how to hold the control device 30. As a result, the control device 30 can more accurately estimate the installation direction of the lighting fixture 20.

[0061] Furthermore, while Figure 10 shows an example where the information processing unit 34 distinguishes and displays information regarding the installation direction of the lighting fixture 20 in four directions, it may also distinguish and display in two or three directions, or even more finely distinguish and display in five or more directions. In other words, the information processing unit 34 only needs to distinguish and display information regarding the installation direction of the lighting fixture 20 in n directions (where n is a natural number of 2 or more).

[0062] [Another initial setup operation related to the embodiment] Similarly, an example of operation in which the control device 30 estimates (in other words, identifies) the installation direction of multiple lighting fixtures 20 and displays multiple icons 322 indicating the estimated (in other words, identified) installation direction on the initial setup screen will be described. Figure 11 is a sequence diagram showing a second example of the initial setup operation according to this embodiment. Note that Figure 11 is a sequence diagram in which the control device 30 is executed by a general-purpose terminal device that is also used in a communication system 10. In other words, Figure 11 is a sequence diagram in which the control device 30 is executed by a control device 30 in which a dedicated application is stored in the storage unit 35.

[0063] The process in step S301 is as described above. Furthermore, the process in step S321 is the same as the process in step S311 in Figure 8.

[0064] After step S321, the information processing unit 34 displays an icon 322 on the display unit 32 corresponding to the lighting fixture 20, which is the source of the first radio signal received by the wireless communication unit 33 (S322). Note that the lighting fixture icon 322 displayed in step S322 does not show any information regarding the estimated installation direction.

[0065] The operation reception unit 31 receives a selection operation from the user for one of several icons 322 (S323). The information processing unit 34 sends a blinking command (second wireless signal) via the mesh network to the target lighting fixture 20 corresponding to the selected icon 322 (S324).

[0066] When the target lighting fixture 20 receives a flashing command, it flashes (S325). This allows the user to visually confirm the actual installation direction of the flashing target lighting fixture 20 (S326). The operation reception unit 31 then receives input from the user regarding the installation direction of the target lighting fixture 20 (S327).

[0067] The information processing unit 34 calculates the time difference when the first radio signal is received by the multiple receiving antennas 331 of the wireless communication unit 33 (S328). Based on the installation direction of the target lighting fixture 20 received in step S327 and the time difference calculated in step S328, the information processing unit 34 estimates (in other words, identifies) the installation direction of the lighting fixture 20 that is the source of the first radio signal (S329). Then, the information processing unit 34 displays multiple icons 322 on the display unit 32 that include information about the installation direction of the lighting fixture 20 estimated (in other words identified) in step S329 (S330).

[0068] The processes described above in steps S301, S321-S330, and S303-S309 are the processes performed in the identification and registration phase S30 in another initial setup operation according to this embodiment. In step S328, the information processing unit 34 may calculate the phase difference of the first radio signal received by the multiple receiving antennas 331.

[0069] Such a control device 30 estimates the installation direction of the remaining lighting fixtures 20 based on user input regarding the installation direction of at least one controlled device 20 whose control state has been changed. This allows the control device 30 to accurately estimate the installation direction of the controlled devices 20 even if it is a general-purpose terminal device, rather than a dedicated terminal device where multiple receiving antennas 331 are located at specific positions.

[0070] [Variations in the display method of information regarding the installation direction of lighting fixtures] The information regarding the installation direction of the lighting fixture 20 shown on the initial setup screen should be the installation direction of the lighting fixture 20 estimated by the information processing unit 34. The following describes variations in the display of the information regarding the installation direction of the lighting fixture 20.

[0071] Figure 12 shows a first modified example of the display method for information regarding the installation direction of the lighting fixture 20. As shown in Figure 12, the information processing unit 34 may display information regarding the installation direction of the lighting fixture 20 (i.e., the installation direction of the lighting fixture 20) in words. The words may be, for example, words such as "right," "left," "front," and "back." In the example shown in Figure 12, the estimated installation direction of the lighting fixture 20 is shown according to the words displayed under multiple icons 322. Specifically, an icon 322 containing the word "right" means that the lighting fixture 20 corresponding to that icon 322 is installed to the right as viewed from the control device 30. The words may also be words indicating directions such as "east," "west," "south," and "north."

[0072] Furthermore, the information processing unit 34 may display multiple icons 322 on the display unit 32 that include information regarding the reception strength of the first radio signal transmitted from the lighting fixture 20, in addition to information regarding the installation direction of the lighting fixture 20. For example, if the wireless communication unit 33 measures the reception strength of the first radio signal when it receives the first radio signal, the information processing unit 34 can display multiple icons 322 on the display unit 32 that include information regarding the reception strength of the first radio signal measured by the wireless communication unit 33. Figure 13 shows a second modified example of the display of information regarding the installation direction of the lighting fixture 20. As shown in Figure 13, the information processing unit 34 may display multiple icons 322 that include information regarding the reception strength of the first radio signal (in Figure 13, symbols such as antennas) in addition to information regarding the installation direction of the lighting fixture 20. In the example shown in Figure 13, the difference in reception strength of the first radio signal is shown according to the number of antennas, indicating that the more antennas there are, the stronger the reception strength of the first radio signal. In other words, Icon 322 containing a symbol with many antennas means that the reception strength of the first radio signal is high (i.e., the distance between the control device 30 and the lighting fixture 20 is short), and Icon 322 containing a symbol with few antennas means that the reception strength of the first radio signal is low (i.e., the distance between the control device 30 and the lighting fixture 20 is far).

[0073] Although the example shown illustrates the information processing unit 34 displaying information regarding the received strength of the first radio signal in three distinct stages, it may also display it in two stages, or even in four or more finely divided stages. In other words, the information processing unit 34 only needs to display information regarding the received strength of the first radio signal in n stages (where n is a natural number greater than or equal to 2). Furthermore, the threshold used to distinguish the received strength of the first radio signal may be a value set by the information processing unit 34 (initial value), or a value set by the user.

[0074] In this way, the information processing unit 34 indicates not only the installation direction of the lighting fixture 20 but also the reception strength of the first wireless signal, making it easier for the worker to predict the installation position of the lighting fixture 20 when visually inspecting the fixture, thereby shortening the setup time.

[0075] Furthermore, information indicating the installation direction of the lighting fixture 20 may be displayed in a manner other than that shown by the icon 322 itself, as in the examples shown in Figures 12 and 13. For example, the information processing unit 34 may display a table (display screen) on the display unit 32 that associates multiple icons 322 with the estimated installation direction of the lighting fixture 20. The display screen may be displayed as a pop-up (overlaid display) on the initial settings screen, for example.

[0076] [Update multiple icons] The control device 30 may update multiple icons 322 containing information about the installation direction of the lighting fixture 20 in real time by continuously receiving the first wireless signal. Whether or not the control device 30 updates the multiple icons 322 in real time may be set as appropriate by the user.

[0077] For example, the information processing unit 34 may update a plurality of icons 322 containing information about the installation direction of the lighting fixture 20 each time the first wireless signal is received by the wireless communication unit 33, and display them on the display unit 32. Figure 14 is a flowchart showing an example of the operation by which the information processing unit 34 updates a plurality of icons 322 containing information about the installation direction of the lighting fixture 20 and displays them on the display unit 32.

[0078] First, the information processing unit 34 determines whether or not a first radio signal has been newly received by the wireless communication unit 33 (S401).

[0079] If the information processing unit 34 determines that a first radio signal has been newly received (Yes in S401), it calculates the time difference when the first radio signal was received using the multiple receiving antennas 331 of the wireless communication unit 33, and estimates the installation direction of the lighting fixture 20, which is the source of the first radio signal, based on the calculated time difference (S402). The information processing unit 34 updates the information regarding the installation direction of the lighting fixture 20 estimated in step S402 into multiple icons 322 and displays them on the display unit 32 (S403). On the other hand, if the information processing unit 34 determines that a first radio signal has not been newly received (No in S401), it does not update the multiple icons 322 (S404). In other words, the information processing unit 34 does not change the multiple icons 322 displayed on the display unit 32.

[0080] Furthermore, a specific example of the initial setup screen when multiple icons 322 are updated by the information processing unit 34 will be described.

[0081] For example, the information processing unit 34 may delete the icon 322 corresponding to the lighting fixture 20, which is the source of the first wireless signal that can no longer be received, from the initial setup screen, or it may display it on the initial setup screen in the same way it was displayed before the first wireless signal could no longer be received.

[0082] Furthermore, the information processing unit 34 may or may not display the icon 322 corresponding to the lighting fixture 20, which is the source of the newly received first wireless signal, on the initial setup screen. When the information processing unit 34 displays a new icon 322 on the initial setup screen, the information processing unit 34 may change the display manner of the multiple icons 322 so that it can identify the timing at which each icon 322 was displayed on the initial setup screen. For example, as shown in Figure 15, the information processing unit 34 may display the second icon 322b, which was displayed on the initial setup screen at a newer timing, in a darker color, and the first icon 322a, which was displayed on the initial setup screen at an older timing, in a lighter color (grayed out). Figure 15 is a diagram showing a first example of the initial setup screen when multiple icons 322 have been updated.

[0083] Furthermore, when the information processing unit 34 displays an icon 322 (an unplaced icon 322c) on the initial setup screen before the identification information of the lighting fixture 20 and the installation position of the lighting fixture 20 are associated, and then displays an icon 322 (a new icon 322d) corresponding to the lighting fixture 20 that is the source of the newly received first wireless signal on the initial setup screen, the unplaced icon 322c may be displayed before or after the new icon 322d. For example, as shown in Figure 16, the unplaced icon 322c (in the example in Figure 16, the icons 322 with identification numbers L001 to L003) may be displayed to the left of the new icon 322d (in the example in Figure 16, the icons 322 with identification numbers L004 to L014). Furthermore, as shown in Figure 17, the new icon 322d (in the example in Figure 17, the icon 322 with identification numbers L004 to L017) may be displayed to the left of the unplaced icon 322c (not shown in the example in Figure 17). The information processing unit 34 may also rearrange and display multiple icons 322 according to the device type or identification number. Figure 16 is a diagram showing a second example of the initial setup screen when multiple icons 322 have been updated, and Figure 17 is a diagram showing a third example of the initial setup screen when multiple icons 322 have been updated.

[0084] In this way, the control device 30 updates multiple icons 322 containing information about the installation direction of the lighting fixture 20 and displays them on the display unit 32, for example, when the user operating the control device 30 moves. This allows the control device 30 to provide the user with the latest information.

[0085] [Example of initial setup screen] In step S314 of Figure 8, or step S330 of Figure 11, the display process of the icon 322 is described in an example in which the information processing unit 34 displays multiple icons 322 corresponding to the lighting fixture 20, which is the source of the received first radio signal, on the display unit 32. However, the information processing unit 34 may display only some of the multiple icons 322 on the display unit 32. Figure 18 is a flowchart of operation example 1 for the information processing unit 34 to display some of the multiple icons 322 on the display unit 32. In order to realize the flowchart shown in Figure 18, the wireless communication unit 33 of the control device 30 measures the received strength of the first radio signal in step S112 of Figure 8 or step S122 of Figure 11.

[0086] First, the information processing unit 34 determines whether the received strength of the first radio signal measured by the wireless communication unit 33 is above a predetermined threshold (S501).

[0087] If the information processing unit 34 determines that the measured received strength of the first radio signal is above a predetermined threshold (Yes in S501), it displays an icon 322 corresponding to the lighting fixture 20 that is the source of the first radio signal on the display unit 32 (S502). On the other hand, if the measured received strength of the first radio signal is below a predetermined threshold (No in S501), the information processing unit 34 does not display an icon 322 corresponding to the lighting fixture 20 that is the source of the first radio signal on the display unit 32 (S503).

[0088] Furthermore, Figure 19 is a flowchart illustrating an example of operation 2 in which the information processing unit 34 displays some of the icons 322 out of a plurality of icons 322 on the display unit 32. In order to realize the flowchart shown in Figure 19, the wireless communication unit 33 of the control device 30 measures the received strength of the first wireless signal in step S112 of Figure 8 or step S122 of Figure 11.

[0089] First, the information processing unit 34 determines whether the wireless communication unit 33 has received a first wireless signal from more than a predetermined number of lighting fixtures 20 (S601).

[0090] If the information processing unit 34 determines that it has received the first radio signal from more than a predetermined number of lighting fixtures 20 (Yes in S601), it selects icons 322 corresponding to the lighting fixtures 20 up to a predetermined number, in descending order of the received signal strength of the first radio signal measured by the wireless communication unit 33, and displays them on the display unit 32 (S602). On the other hand, if the information processing unit 34 determines that the wireless communication unit 33 has not received the first radio signal from more than a predetermined number of lighting fixtures 20 (No in S601), it displays all the icons 322 corresponding to the lighting fixtures 20 that are the sources of the received first radio signal on the display unit 32 (S603).

[0091] Figure 20 shows an example of an initial setup screen when some of the multiple icons 322 are displayed on the display unit 32. As shown in Figure 20, for example, the icon 322 corresponding to the lighting fixture 20 with identification number "L002" is not displayed on the display unit 32, while some icons 322 are displayed. In this way, the information processing unit 34 displays icons 322 that meet predetermined conditions on the display unit 32, so the user only needs to focus on the controlled equipment 20 located nearby when visually confirming the target controlled equipment 20, thereby shortening the setup time.

[0092] [Other variations] In the above embodiment, an example was described in which the multiple controlled devices 20 were multiple lighting fixtures 20, but they do not have to be multiple lighting fixtures 20. The multiple controlled devices 20 may be multiple lighting fixtures 20 and multiple other devices, or they may be multiple other devices alone.

[0093] Other devices mentioned above include a remote lighting controller, a PWM (Pulse Width Modulation) dimmer, a scheduler, and an AC (Alternating Current) relay, which are operated by the user to control the lighting fixture 20.

[0094] A PWM dimmer is a device that can dim the lighting fixture 20 attached to the PWM dimmer. A scheduler is a device that turns the lighting fixture 20 on, off, or dims it according to a pre-set schedule.

[0095] AC relays include the following two types: first AC relay and second AC relay. The first AC relay is a device that is mounted on a wiring duct and can turn on and off a single device mounted on the wiring duct by switching the AC power to that device on and off. The second AC relay is a device that is mounted at the base of a wiring duct and can turn on and off all devices mounted on the wiring duct by switching the AC power supply to the wiring duct on and off. Alternatively, an AC relay may be a wireless control switch or the like that does not utilize a wiring duct.

[0096] Furthermore, the other devices mentioned above may include devices not directly related to lighting, such as air conditioners, ventilation systems, cameras, speakers, motion sensors, or environmental sensors. Environmental sensors include temperature sensors, humidity sensors, carbon dioxide concentration sensors, and PM (Particle Matter) sensors.

[0097] [Effects, etc.] The above describes examples of inventions that can be obtained from the disclosures in this specification, and explains the effects and other benefits that can be obtained from such inventions.

[0098] Invention 1 comprises a wireless communication unit 33 that communicates with each of the multiple controlled devices 20 and receives a first wireless signal transmitted from each of the multiple controlled devices 20, a display unit 32, and an information processing unit 34. The information processing unit 34 estimates the installation direction of the multiple controlled devices 20 based on the received first wireless signal, displays multiple icons 322 corresponding to the multiple controlled devices 20 on the display unit 32, transmits a second wireless signal via the wireless communication unit 33 to the controlled device 20 corresponding to the icon 322 selected by the user from among the multiple icons 322 to change the control state of the controlled device 20, and registers the identification information of the controlled device 20 and the installation position of the controlled device 20 in association with each other in the storage unit 35 based on the user's operation to register the installation position of the controlled device 20 whose control state has been changed. The multiple icons 322 are control devices 30 that include information about the estimated installation direction.

[0099] Since the control device 30 displays multiple icons 322 on the display unit 32 that contain information about the installation direction of the controlled device 20, the user can more easily predict the installation position of the controlled device 20 by visually inspecting the device, thereby reducing the time required for setup. As a result, the control device 30 can improve the efficiency of the mapping work for the controlled device 20.

[0100] Invention 2 is a control device 30 of Invention 1, wherein the information processing unit 34 estimates the installation direction of the controlled device 20, which is the source of the newly received first radio signal, each time the first radio signal is received by the wireless communication unit 33, updates a plurality of icons 322 containing information about the newly estimated installation direction, and displays them on the display unit 32.

[0101] Each time the reception strength of the first wireless signal is measured, the control device 30 displays updated icons 322 on the display unit 32, thereby providing the user with the latest information.

[0102] Invention 3 is a control device 30 of Invention 1 or Invention 2, wherein the wireless communication unit 33 has a plurality of receiving antennas 331 that receive a first wireless signal, and the information processing unit 34 estimates the installation direction by calculating the time difference when the first wireless signal is received by the plurality of receiving antennas 331.

[0103] Such a control device 30 can display information regarding the installation direction of the controlled device 20, estimated based on the time difference when the first radio signal is received, on the display unit 32.

[0104] Invention 4 is a control device 30 of Invention 3, wherein the information processing unit 34 changes the control state of at least one of the multiple controlled devices 20 before estimating the installation direction of the multiple controlled devices 20, and estimates the installation direction of the controlled devices 20 other than the at least one controlled device 20 based on user input regarding the installation direction of the at least one controlled device 20 whose control state has been changed.

[0105] Such a control device 30 estimates the installation direction of the remaining lighting fixtures 20 based on user input regarding the installation direction of at least one controlled device 20 whose control state has been changed. This allows the control device 30 to accurately estimate the installation direction of the controlled devices 20 even if it is a general-purpose terminal device, rather than a dedicated terminal device where multiple receiving antennas 331 are located at specific positions.

[0106] Invention 5 is a control device 30 of any of Inventions 1 to 4, wherein the information processing unit 34 displays a notification screen 326 on the display unit 32 for specifying to the user how to hold the control device 30 before estimating the installation direction of the controlled device 20.

[0107] Such a control device 30 can reduce the influence of how the control device 30 is held by displaying a notification screen 326 on the display unit 32 for the user to specify how to hold the control device 30. As a result, the control device 30 can more accurately estimate the installation direction of the lighting fixture 20.

[0108] Invention 6 is a control device 30 of any of Inventions 1 to 5, wherein the wireless communication unit 33 measures the received strength of the first wireless signal, and the information processing unit 34 displays on the display unit 32 the icon 322 that corresponds to the controlled device 20 for which the measured received strength of the first wireless signal is above a predetermined threshold, and does not display on the display unit 32 the icon 322 that corresponds to the controlled device 20 for which the measured received strength of the first wireless signal is below a predetermined threshold.

[0109] Since the control device 30 displays icons 322 corresponding to controlled devices 20 that are estimated to be installed within a certain distance from the control device 30, the user only needs to focus on the controlled devices 20 installed nearby when visually confirming the target controlled devices 20, thereby shortening the setup time. As a result, the control device 30 can further improve the efficiency of the mapping work of controlled devices 20.

[0110] Invention 7 is a control device 30 that is one of Inventions 1 to 5, wherein the wireless communication unit 33 measures the received strength of the first wireless signal, and the information processing unit 34 displays on the display unit 32 icons 322 that correspond to a predetermined number of controlled devices 20, in descending order of the measured received strength of the first wireless signal.

[0111] Such a control device 30 displays a predetermined number of icons 322 corresponding to the controlled devices 20 that are presumed to be installed near the control device 30. Therefore, when visually confirming the target controlled device 20, the user only needs to focus on the controlled devices 20 installed nearby, thereby shortening the setup time. As a result, the control device 30 can further improve the efficiency of the mapping work of the controlled devices 20.

[0112] Invention 8 is a communication system 10 comprising a control device 30 from any of Inventions 1 to 7 and a plurality of controlled devices 20.

[0113] Such a communication system 10 provides the same effects as the control device 30 described above.

[0114] Invention 9 is a control method performed by a control device 30 equipped with a display unit 32, wherein the control device 30 communicates with each of a plurality of controlled devices 20, receives a first radio signal transmitted from each of the plurality of controlled devices 20, and the control method includes the steps of estimating the installation direction of the plurality of controlled devices 20 based on the received first radio signal (S313 or S329), and displaying a plurality of icons 322 corresponding to the plurality of controlled devices 20 on the display unit 32 (S314 or S330), and the plurality of icons 322 The control method includes the steps of: transmitting a second wireless signal to the controlled device 20 corresponding to the icon 322 selected by the user (S303-S304) to change the control state of the controlled device 20; and registering the identification information of the controlled device 20 and the installation location of the controlled device 20 in association with each other in the storage unit 35 (S307-S308) based on the user's operation to register the installation location of the controlled device 20 whose control state has been changed, wherein the multiple icons 322 include information about the estimated installation direction.

[0115] This control method displays multiple icons 322 on the display unit 32 that contain information about the installation direction of the controlled device 20. As a result, the user can more easily predict the installation position of the controlled device 20 by visually inspecting it, and the setup time can be reduced. This allows the control method to improve the efficiency of the mapping work for the controlled device 20.

[0116] Invention 10 is a program for causing the control device 30 to execute the control method of Invention 9.

[0117] Such a program produces the same effects as the control method described above.
