[0002] Previously, lighting systems with multiple wireless lighting fixtures capable of wireless communication were known. As an example of such a lighting system, Patent Document 1 discloses a lighting system comprising multiple wireless lighting fixtures and a terminal device (setter) that associates the location information of the multiple wireless lighting fixtures with their inherent addresses.

[0006] The problem the invention aims to solve

[0007] As described above, in a lighting system, a terminal device is used to set a mapping that associates the location information of a wireless lighting fixture with its inherent address. However, in the lighting system described in Patent Document 1, for example, if the location identification of a wireless lighting fixture whose lighting state has changed is incorrect, the mapping setting of the lighting system will be incorrect.

[0008] Therefore, the object of the present invention is to provide a terminal device or the like that can suppress errors in the mapping settings of a lighting system.

[0010] One embodiment of the terminal device of the present invention includes: a communication unit that performs wireless communication; a display unit that displays multiple icons corresponding to the locations of multiple wireless lighting devices and the inherent addresses of the multiple wireless lighting devices; and a control unit that controls the communication unit and the display unit, wherein, when the control unit receives a mapping input that associates the icon of a specified wireless lighting device among the multiple wireless lighting devices with the inherent address of the specified wireless lighting device, it compares the communication quality of the specified wireless lighting device obtained via the communication unit with the communication quality corresponding to the location of the specified wireless lighting device, thereby determining whether there is a possibility of error in the mapping input.

[0011] One embodiment of the lighting system of the present invention comprises: the terminal device described above; a communication interface for communicating with the terminal device; and a plurality of wireless lighting devices for communicating with the communication interface.

[0012] One aspect of the mapping setting method for the lighting system of the present invention is to perform a mapping setting method for a lighting system having multiple wireless lighting devices by associating the location information of multiple wireless lighting devices with their inherent addresses. The mapping setting method includes the following steps: receiving a mapping input that associates the location information of a specified wireless lighting device among the multiple wireless lighting devices with the inherent address of the specified wireless lighting device; and comparing the communication quality of the specified wireless lighting device obtained from the outside with the communication quality corresponding to the location of the specified wireless lighting device, thereby determining whether there is a possibility of error in the mapping input.

[0030] (How the present invention was obtained)

[0031] The lighting system includes multiple wireless lighting fixtures that can communicate wirelessly, as well as terminal devices for setting various parameters of the multiple wireless lighting fixtures. The multiple wireless lighting fixtures are installed on, for example, building structural components (ceilings, etc.).

[0032] To control the illumination of multiple wireless lighting fixtures installed on building components, it is necessary to know the location information and inherent address of each wireless lighting fixture. Therefore, after installing multiple wireless lighting fixtures in the building, a mapping setting is required to establish an association between the location information and inherent address of each wireless lighting fixture.

[0033] Figure 1 This diagram illustrates a scenario where the mapping settings for lighting system 1 are configured. In this example, an example is described where two lighting systems 1, 101 are installed on the same floor of a building. Furthermore, this example is for understanding the implementation method and is not prior art.

[0034] Operators that perform mapping settings, for example Figure 1 As shown in (a), the operator selects the intrinsic address ua of the wireless lighting device 30 displayed on the screen of the terminal device 10, causing the wireless lighting device 30 corresponding to the selected intrinsic address ua to flash, thereby indicating the relationship between the position of the wireless lighting device 30 and the intrinsic address ua. Then, the operator drags the selected intrinsic address ua on the screen and overlays it onto the icon 18 corresponding to the wireless lighting device 30, thereby establishing an association between the position information of the wireless lighting device 30 and the intrinsic address ua.

[0035] Here, we will describe the scenario where the mapping settings for one lighting system 1 and the other lighting system 101 are simultaneously performed using both terminal device 10 and terminal device 110. In this case, the mapping settings for one lighting system 1 may sometimes malfunction due to the operation of the wireless lighting fixture 130 of the other lighting system 101. For example... Figure 1 As shown in (b), sometimes operators may mistakenly identify a wireless lighting fixture 130 that flashes due to the operation input of the other party's terminal device 110 as a wireless lighting fixture 30 that flashes according to the flashing command of one party's lighting system 1, thus incorrectly mapping the icon 118 corresponding to the wireless lighting fixture 130. When the mapping setting is incorrect, it is necessary to flash multiple wireless lighting fixtures one by one to confirm and find the incorrectly set wireless lighting fixture 30 or 130, which requires a lot of effort.

[0036] In contrast, the terminal device 10 and the like of this embodiment have the structure shown below, thereby suppressing errors in the mapping settings of the lighting system 1.

[0037] The embodiments will now be described in detail with reference to the accompanying drawings. Furthermore, the embodiments described below are all intended to illustrate a specific example of the present invention. The numerical values, shapes, materials, structural elements, the arrangement and connection methods of structural elements, steps, and the order of steps shown in the following embodiments are examples and are not intended to limit the present invention. Additionally, structural elements in the following embodiments that are not described in the independent claims representing an implementation of the present invention are described as arbitrary structural elements. The implementation of the present invention is not limited to the present independent claims and can also be expressed through other independent claims.

[0038] Furthermore, the figures are schematic diagrams and may not be strictly representational. Additionally, substantially identical structures are labeled with the same reference numerals across the figures, and sometimes repetitive descriptions are omitted or simplified.

[0039] (Implementation Method 1)

[0040] [1-1. Overall Structure of the Lighting System]

[0041] Reference Figure 2 and Figure 3 The overall structure of the lighting system 1 involved in Embodiment 1 will be explained.

[0042] Figure 2 This is a schematic diagram illustrating the lighting system 1 according to Embodiment 1. Figure 3 This is a module structure diagram of lighting system 1.

[0043] The lighting system 1 involved in this embodiment includes multiple wireless lighting devices 30, a communication interface 40, and a terminal device 10.

[0044] Multiple wireless lighting fixtures 30 and communication interface 40 can communicate via wireless r1. As a communication method via wireless r1, specific low-power wireless, Zigbee (registered trademark), Bluetooth (registered trademark), or WiFi (registered trademark) methods utilizing the 920MHz frequency band can be used.

[0045] The communication interface 40 and the terminal device 10 can communicate wirelessly via r2. As a communication method via r2, WiFi (registered trademark) or similar methods can be used.

[0046] The communication interface 40 consists of a wireless access point 41 and a wireless controller 42. The wireless access point 41 is a device for communication access between multiple wireless lighting fixtures 30, and it communicates with the multiple wireless lighting fixtures 30 via wireless r1. The wireless controller 42 communicates with the terminal device 10 via wireless r2. The wireless access point 41 and the wireless controller 42 are wired together.

[0047] Furthermore, wireless access point 41 and wireless controller 42 can also communicate wirelessly. Communication interface 40 can also communicate with a management server that manages the operation of lighting system 1. Figure 2 and Figure 3 In this embodiment, the communication interface 40 consists of a wireless access point 41 and a wireless controller 42, but is not limited to these. For example, the communication interface 40 may also consist of only the wireless access point 41, which can communicate with the terminal device 10 via wireless r2.

[0048] [1-2. Structure of Wireless Lighting Fixtures, Communication Interfaces, and Terminal Devices]

[0049] Reference Figures 2-9 To illustrate the structure of the multiple wireless lighting devices 30, communication interface 40, and terminal device 10 of the lighting system 1 described above.

[0050] Figure 4 This is a diagram showing an example of the configuration of the wireless lighting fixture 30 and the wireless access point 41 of the lighting system 1.

[0051] Wireless lighting fixtures 30, such as LED lights, are installed on building components. Figure 4 The diagram shows 18 wireless lighting fixtures 30a, 30b, 30c, 30d, 30e, 30f, 30g, 30h, 30i, 30j, 30k, 30L, 30m, 30n, 30o, 30p, 30q, and 30r, but is not limited to these; more than 100 wireless lighting fixtures 30 may be installed on building components. Hereinafter, sometimes all or one of the multiple wireless lighting fixtures 30a to 30r will be referred to as wireless lighting fixture 30.

[0052] like Figure 3 As shown, the wireless lighting device 30 includes a communication unit 31, a measurement unit 33, a lighting unit 37, and a control unit 35.

[0053] The communication unit 31 consists of a wireless module including an antenna. The communication unit 31 communicates with the wireless access point 41 of the communication interface 40 via wireless r1. The lighting unit 37 includes, for example, multiple light-emitting diodes or other light sources that emit white, red, green, or blue light.

[0054] The control unit 35 consists of a microprocessor and a memory. For example, the control unit 35 controls the operation of the communication unit 31, the measurement unit 33, and the lighting unit 37 based on control signals sent from the terminal device 10 and the communication interface 40. The memory stores the inherent address ua of the wireless lighting device 30 itself. The inherent address ua can be a MAC address (Media Access Control address) or a communication address.

[0055] The measurement unit 33 is a detection device that measures the received signal strength (RSSI) of the wireless lighting fixture 30. The measurement unit 33 measures the radio wave strength of the signal transmitted from the wireless access point 41. The radio wave strength is an example of the communication quality Q1 described later. The radio wave strength can also be the average radio wave strength over a specified period. The radio wave strength measured by the measurement unit 33, along with the inherent address ua of the wireless lighting fixture 30, is transmitted to the communication interface 40 via the communication unit 31.

[0056] The communication interface 40, like the wireless lighting fixture 30, is installed on the building component. In this embodiment, the wireless access point 41 of the communication interface 40 is fixed to the building component.

[0057] Communication interface 40 is a communication device that connects the wireless lighting fixture 30 to the terminal device 10. For example, communication interface 40 converts the lighting indication signal of the wireless lighting fixture 30 sent from the terminal device 10 into a signal readable by the wireless lighting fixture 30, and sends this signal to the wireless lighting fixture 30. In addition, communication interface 40 converts signals containing information such as radio wave intensity and inherent address ua sent from each wireless lighting fixture 30 into signals readable by the terminal device 10, and sends this signal to the terminal device 10.

[0058] Furthermore, while the example of the wireless lighting fixture 30 measuring radio wave intensity has been shown above, it is not limited to this. For example, the wireless access point 41 may have a measurement unit that measures the radio wave intensity of the signal transmitted from the wireless lighting fixture 30.

[0059] Terminal device 10 is a device for controlling the lighting of wireless lighting fixtures 30 via communication interface 40. In this embodiment, terminal device 10 is used to configure a mapping that associates the location information (IP) of multiple wireless lighting fixtures 30 with their inherent addresses (UA).

[0060] Figure 5 This is a top view showing the terminal device 10.

[0061] like Figure 3 and Figure 5As shown, the terminal device 10 includes a communication unit 11, a display unit 17, a control unit 15, and a storage unit 16. The terminal device 10 is, for example, a tablet terminal or a portable terminal.

[0062] The communication unit 11 consists of a wireless module including an antenna. The communication unit 11 communicates with the communication interface 40 via wireless r2.

[0063] Figure 6 This is a diagram showing an example of a screen displayed on the display unit 17 of the terminal device 10.

[0064] like Figure 6 As shown, the display unit 17 displays multiple icons 18 corresponding to the respective positions of multiple wireless lighting fixtures 30 within the building. The positional relationship of the multiple icons 18 is the same as the positional relationship of the multiple wireless lighting fixtures 30 installed on the building components. For example, when the multiple wireless lighting fixtures 30 are arranged in 3 rows and 6 columns, the multiple icons 18 are also displayed in 3 rows and 6 columns on the display unit 17. Furthermore, the display unit 17 displays location information (IP) indicating the position of each of the multiple wireless lighting fixtures 30 in each of the multiple icons 18. Figure 6 The display unit 17 shows an icon 18 of the wireless lighting fixture 30 included in the lighting system 1, but it may also display the other lighting system 101 (see reference). Figure 1 The icon for wireless lighting appliances.

[0065] In addition, the display unit 17 displays the unique addresses ua of each of the multiple wireless lighting devices 30. Each unique address ua is displayed, for example, in a list format within a portion of the display unit 17.

[0066] The display unit 17 is, for example, a touch panel, and also functions as an input unit for receiving various operation inputs. For example, when the display unit 17 receives a key operation input for flashing a specified wireless lighting appliance 30 that is the object of the mapping setting, it outputs a signal to the control unit 15 indicating that the key operation input has been received.

[0067] The control unit 15 is, for example, composed of a microprocessor. The control unit 15 controls the communication unit 11, the display unit 17, and the storage unit 16. When the control unit 15 receives the aforementioned key operation input via the display unit 17, it sends a flashing indication signal via the communication unit 11 to cause the wireless lighting fixture 30 corresponding to the designated icon 18 to flash. Furthermore, the control unit 15 acquires information related to the communication quality Q1 output from each wireless lighting fixture 30 via the communication interface 40, and displays this information on the display unit 17. The communication quality Q1 is, for example, the radio wave strength between the wireless access point 41 and each wireless lighting fixture 30. The information related to the communication quality Q1 displayed on the display unit 17 can be a value of the radio wave strength or a radio wave indicator representing the radio wave strength.

[0068] The storage unit 16 consists of a memory and programs stored in the memory. The storage unit 16 stores map information (layout information) of the building. Specifically, the storage unit 16 stores location information IPs of the wireless access point 41 and multiple wireless lighting fixtures 30. The location information IPs are, for example, the coordinates of the wireless access point 41 and the multiple wireless lighting fixtures 30 within the building. The location information IPs may also include information related to the distance between each wireless lighting fixture 30 and the wireless access point 41. Furthermore, the distance between each wireless lighting fixture 30 and the wireless access point 41 can be calculated by the control unit 15.

[0069] Additionally, the storage unit 16 stores the unique address ua of each wireless lighting device 30. However, before the mapping setting of the lighting system 1 is performed, the location information IP and the unique address ua are not yet associated. The location information IP and the unique address ua are associated through the mapping setting operation.

[0070] In addition, the storage unit 16 stores the communication quality Qr and threshold Qth used for comparison in evaluating the communication quality Q1 of each wireless lighting device 30. The communication quality Qr and threshold Qth used for comparison will be described later.

[0071] Here, the scenario of setting up the mapping for the lighting system 1 will be described to provide a more detailed explanation of the various structures of the lighting system 1.

[0072] When the control unit 15 receives a key operation input corresponding to a designated icon 18 displayed on the display unit 17, it sends a flashing indication signal via the communication unit 11 to cause the wireless lighting fixture 30 corresponding to the designated icon 18 to flash. The wireless lighting fixture 30 receives the flashing indication signal via the communication interface 40 and flashes based on the flashing indication signal. The operator performing the mapping settings confirms the position of the flashing wireless lighting fixture 30 and inputs information to the terminal device 10.

[0073] In the terminal device 10, for example, the inherent address ua of the display unit 17 can be dragged and overlaid onto the icon 18, thereby establishing an association between the location information ip of the wireless lighting device 30 and the inherent address ua. In this way, the control unit 15 receives the mapping input via the display unit 17, which establishes an association between the location information ip of a specified wireless lighting device among a plurality of wireless lighting devices 30 and the inherent address ua of a specified wireless lighting device 30.

[0074] Upon receiving the mapping input, the control unit 15 compares the communication quality Q1 of the specified wireless lighting fixture 30, obtained via the communication unit 11, with the comparison communication quality Qr corresponding to the specified location of the wireless lighting fixture 30, thereby determining whether there is a possibility of an error in the mapping input. Specifically, if the difference between the value of the specified wireless lighting fixture 30's communication quality Q1 (evaluation value) and the value of the comparison communication quality Qr (evaluation value) is greater than or equal to a predetermined threshold Qth, the control unit 15 determines that there is a possibility of an error in the mapping input. Furthermore, the value of the comparison communication quality Qr is a value pre-stored in the storage unit 16, and the threshold Qth is an allowable value for the difference between the value of the communication quality Q1 and the value of the comparison communication quality Qr.

[0075] Figure 7 This is a graph showing the radio wave strength as an example of the communication quality Q1 between the wireless access point 41 and the wireless lighting fixture 30. Figure 7 The horizontal axis represents the distance between the wireless access point 41 and the wireless lighting fixture 30, and the vertical axis represents the radio wave intensity (radio wave attenuation) between the wireless access point 41 and the wireless lighting fixture 30. Additionally, the theoretical radio wave attenuation model is shown in this figure. As the figure illustrates, the longer the distance between the wireless access point 41 and the wireless lighting fixture 30, the weaker the radio wave intensity.

[0076] In this embodiment, the radio wave attenuation model is used to determine the value of the communication quality Qr and the threshold Qth for comparison. However, since the radio wave intensity varies depending on the distance between the wireless access point 41 and the wireless lighting fixture 30, the value of the communication quality Qr and the threshold Qth for comparison are determined based on the aforementioned distance.

[0077] For example, when observing a wireless lighting fixture 30 located 10m away from wireless access point 41, the theoretical radio wave intensity is -52dBm. In this case, the comparative communication quality Qr used for comparison to evaluate the actual communication quality Q1 of the wireless lighting fixture 30 located at a distance of 10m is -52dBm.

[0078] The threshold Qth is determined based on the radio wave intensity at a location ±5m from a specified distance. For example, regarding the radio wave intensity at a location ±5m from a distance of 10m, it is -46dBm on the negative distance side and -56dBm on the positive distance side. In this example, the threshold Qth is 6dBm on the negative distance side (the direction in which the radio wave intensity increases) and 4dBm on the positive distance side (the direction in which the radio wave intensity decreases).

[0079] Thus, if the communication quality Q1 of the specified wireless lighting fixture 30 is abnormal, the control unit 15 determines that there is a possibility of an error in the mapping input. Then, the control unit 15 uses the display unit 17 to notify the operator or others of the possibility of an error in the mapping input.

[0080] Figure 8 This is an example of a screen displayed on the terminal device 10 in the event that there is a possibility of an error in the mapped input.

[0081] exist Figure 8 The display shows a message 19 prompting the operator to reconfirm the activation of the wireless lighting fixture 30. Alternatively, if the control unit 15 determines that there is a possibility of an error in the mapping input, the display unit 17 may display the message 19 prompting a reconfirmation of the mapping input.

[0082] Figure 9 This is another example of a screen displayed on the terminal device 10 in the event that there is a possibility of an error in the mapped input.

[0083] exist Figure 9 In the display unit, icons 18 corresponding to wireless lighting fixtures 30 that are likely to have erroneous mapping inputs are shown in a list format. Alternatively, if the control unit 15 determines that there is a possibility of an erroneous mapping input, the display unit 17 may cause it to show at least one of the icons 18 corresponding to the wireless lighting fixtures 30 that are likely to have erroneous inputs and the inherent address ua in a list format.

[0084] The operator performing the mapping settings can also re-enter the mapping input based on the display on the display unit 17. Specifically, it is also possible to make the wireless lighting fixture 30 flash by touching the icon 18 of the wireless lighting fixture 30 that needs to be mapped again, and then re-map the wireless lighting fixture that is flashing.

[0085] In the terminal device 10 according to this embodiment, when a mapping input is received that associates the icon 18 of a specified wireless lighting fixture 30 with its inherent address ua, the communication quality Q1 of the specified wireless lighting fixture 30 is compared with the comparison communication quality Qr to determine whether there is a possibility of an error in the mapping input. Accordingly, if there is a possibility of an error in the mapping input, the operator or others can be notified to check the correctness of the mapping input. As a result, errors in the mapping settings of the lighting system 1 can be suppressed.

[0086] [1-3. Method for Setting the Mapping of Lighting Systems]

[0087] Reference Figure 10 and Figure 11The mapping setting method of the lighting system 1 according to the embodiment will be explained. In addition, in this example, other lighting systems different from lighting system 1 are referred to as the other lighting system 101, the wireless lighting appliances included in the other lighting system 101 are referred to as wireless lighting appliances 130, and the terminal device that performs the mapping setting of the other lighting system 101 is referred to as terminal device 110.

[0088] Figure 10 This is a timing diagram showing a portion of the mapping settings for lighting system 1.

[0089] First, when the terminal device 10 of the lighting system 1 receives a key operation input of a designated icon 18 displayed on the display unit 17 (step S11), it sends a flashing indication signal via the communication unit 11 to cause the wireless lighting appliance (e.g., 30h) corresponding to the designated icon 18 to flash (step S12). The wireless lighting appliance 30h receives the flashing indication signal via the communication interface 40 and flashes based on the flashing indication signal (step S13).

[0090] When the terminal device 110 of the other lighting system 101 receives a key operation input of a specified icon displayed on the display (step S21), it sends a flashing indication signal via the communication unit to cause the wireless lighting appliance 130 corresponding to the specified icon to flash (step S22). The wireless lighting appliance 130 receives the flashing indication signal via the communication interface and flashes based on the flashing indication signal (step S23).

[0091] Here, the operator performing the mapping setting confirms the location of the flashing wireless lighting fixture 30h and inputs it to the terminal device 10. However, when the operator mistakenly identifies the wireless lighting fixture 130 flashing due to the mapping setting of the other party's lighting system 101 as the wireless lighting fixture 30h flashing according to the flashing instruction of lighting system 1, sometimes incorrect mapping input is made for wireless lighting fixture 30h or 130 (step S31). Therefore, in this embodiment, in order to suppress the occurrence of errors in the mapping setting of lighting system 1, the following steps are performed.

[0092] Figure 11 It continues Figure 10 This is a flowchart illustrating the mapping settings of lighting system 1.

[0093] First, the terminal device 10 receives a mapping input that associates the location information (IP) of a specified wireless lighting device 30h among multiple wireless lighting devices 30 with the inherent address (UA) of the specified wireless lighting device 30h. Figure 10 (The steps are the same as in step S31). Specifically, drag the intrinsic address ua of the display unit 17 to overlay it onto the icon 18, thereby establishing an association between the location information IP of the wireless lighting appliance 30h and the intrinsic address ua.

[0094] The terminal device 10 compares the communication quality Q1 of the specified wireless lighting device 30h obtained from the outside with the comparison communication quality Qr corresponding to the location of the specified wireless lighting device 30h. Specifically, the terminal device 10 determines whether the difference between the value of the communication quality Q1 of the specified wireless lighting device 30h and the value of the comparison communication quality Qr is greater than or equal to a predetermined threshold Qth (step S32).

[0095] If the difference between the communication quality Q1 and the comparison communication quality Qr is less than the threshold Qth ("No" in step S32), the terminal device 10 determines that there is no possibility of an error in the mapping input and ends the mapping setting for the wireless lighting fixture 30h.

[0096] If the difference between the communication quality Q1 and the comparison communication quality Qr is greater than or equal to the threshold Qth ("Yes" in S32), the terminal device 10 determines that there is a possibility of an error in the mapped input and displays a message 19 prompting reconfirmation of the mapped input on the display unit 17 (step S33) (see reference). Figure 8 The operator uses message 19 to determine whether to make the wireless lighting fixture 30 flash again.

[0097] The terminal device 10 receives an input via the screen in step S33, asking whether to make the wireless lighting device 30 flash again or cancel the flashing (step S34).

[0098] When the terminal device 10 receives the "cancel" input, it determines that there is no need to reconfirm the mapping settings and ends the mapping settings for the wireless lighting fixture 30h.

[0099] When the terminal device 10 receives the input of "blink again", it causes the wireless lighting device 30h to blink again via the communication unit 11 and the communication interface 40 (step S35).

[0100] Next, the terminal device 10 displays a message 19 on the display unit 17 to confirm whether to cancel the mapping setting (step S36). The operator performing the mapping setting confirms the position of the flashing wireless lighting fixture 30h and determines whether to cancel the mapping setting.

[0101] The terminal device 10 accepts input on the screen in step S36, indicating whether to unmap the settings or not (step S37).

[0102] When the terminal device 10 receives the input "Do not cancel", it determines that there is no need to cancel the mapping setting and ends the mapping setting for the wireless lighting fixture 30h.

[0103] When the terminal device 10 receives the input "cancel", it cancels the previously set mapping settings (step S38). Then, it returns to step S11 and re-sets the mapping of the lighting system 1.

[0104] For other wireless lighting fixtures different from wireless lighting fixture 30h, steps S11 to S38 are performed in the same way. By performing these steps S11 to S38, errors in the mapping settings of lighting system 1 can be suppressed.

[0105] (Implementation Method 2)

[0106] Reference Figure 12 and Figure 13 The lighting system 1A according to Embodiment 2 will be explained. In Embodiment 2, the case in which the communication quality Qr used for comparison is the communication quality of wireless lighting devices located in the vicinity of a specified wireless lighting device 30h will be used as an example for explanation.

[0107] Steps S11 to S23 are the same as in Embodiment 1, so steps S31 and onwards will be described here.

[0108] Figure 12 This is a flowchart illustrating the mapping settings of the lighting system 1A according to Embodiment 2. Furthermore, Figure 12 The flowchart itself and Figure 11 same.

[0109] like Figure 12 As shown, the terminal device 10A accepts a mapping input that associates the location information IP of a specified wireless lighting device (e.g., 30h) among a plurality of wireless lighting devices 30 with the inherent address ua of the specified wireless lighting device 30h (step S31).

[0110] Terminal device 10A compares the communication quality Q1 of a specified wireless lighting fixture 30h obtained from the outside with the communication quality Qr corresponding to the location of the specified wireless lighting fixture 30h.

[0111] The communication quality Qr used for comparison in Implementation 2 is, for example, based on the communication quality Q1 of wireless lighting devices 30a, 30b, 30c, 30g, 30i, 30m, 30n, and 30o located around the wireless lighting device 30h, which is the object of the mapping setting (refer to...). Figure 13The value is determined by the communication quality Qr used for comparison. For example, the value of communication quality Qr is the average of the communication quality Q1 of multiple wireless lighting devices 30b, 30g, 30i, and 30n. The threshold Qth is determined, for example, by the difference between the average and the maximum value, or the difference between the average and the minimum value, of the communication quality Q1 of multiple wireless lighting devices 30b, 30g, 30i, and 30n. Alternatively, the value of communication quality Qr used for comparison can also be the value of communication quality Q1 of a wireless lighting device (e.g., 30m) that is closer to the wireless access point 41 than the specified wireless lighting device 30h.

[0112] Terminal device 10A determines whether the difference between the communication quality Q1 value of the specified wireless lighting device for 30 hours and the communication quality Qr value used for comparison is above a predetermined threshold Qth (step S32).

[0113] If the difference between the communication quality Q1 and the comparison communication quality Qr is less than the threshold Qth ("No" in S32), the terminal device 10A determines that there is no possibility of an error in the mapping input and ends the mapping setting for the wireless lighting fixture 30h.

[0114] If the difference between the communication quality value Q1 and the comparison communication quality value Qr is greater than or equal to the threshold Qth ("Yes" in S32), the terminal device 10A determines that there is a possibility of an error in the mapping input and displays a message 19 prompting the reconfirmation of the mapping input on the display unit 17 (step S33). The subsequent steps are the same as in Embodiment 1.

[0115] In addition, the terminal device 10A can also change the display of the icons 18 corresponding to the wireless lighting appliances 30b, 30g, 30h, 30i, and 30n.

[0116] Figure 13 This diagram illustrates another example of the screen displayed on the terminal device 10A in the event of a potential error in the mapped input. The control unit 15 of the terminal device 10A can also change at least one of the color, shape, and size of the icon 18 displayed on the display unit 17 based on the difference between the communication quality Q1 of the specified wireless lighting devices 30b, 30g, 30h, 30i, and 30n obtained via the communication unit 11 and the comparison communication quality Qr. Figure 13 In the image, different shades of the icon 18 are used to indicate different colors. Based on this, the operator can easily locate wireless lighting fixtures 30 on the screen where there is a possibility of an error in the mapping input.

[0117] (Implementation Method 3)

[0118] Reference Figure 14 and Figure 15The lighting system 1B according to Embodiment 3 will be described. In Embodiment 3, an example will be described in which the functions related to the wireless access point 41 are included in the terminal device 10B and the terminal device 10B is movable.

[0119] Figure 14 This is a module structure diagram of the lighting system 1B according to embodiment 3.

[0120] The lighting system 1B according to Embodiment 3 includes a terminal device 10B and multiple wireless lighting fixtures 30. The terminal device 10B and the multiple wireless lighting fixtures 30 can communicate wirelessly via r2. The terminal device 10B has the same function as the communication interface 40 in Embodiment 1. The terminal device 10B can move freely to different locations within the building.

[0121] Figure 15 This is a diagram showing an example of an image displayed on a terminal device 10B of a lighting system 1B. Figure 15 In (a), an example is shown where the terminal device 10B is positioned near wireless lighting fixtures 30o and 30p located in the center of the lighting system 1B. Figure 15 In (b), an example is shown where the terminal device 10B is configured near the wireless lighting fixture 30r located at the right end of the lighting system 1B.

[0122] In this embodiment, the communication quality Q1 is the radio wave strength between the terminal device 10B, which communicates with multiple wireless lighting devices 30, and a specified wireless lighting device. The control unit 15 determines whether there is a possibility of an error in the mapping input based on the radio wave strength between the terminal device 10B and the multiple wireless lighting devices 30, which changes as the terminal device 10B moves.

[0123] For example, if a wireless lighting fixture with an incorrect mapping input is set as wireless lighting fixture 30r, then... Figure 15 When the terminal device 10B is located in the center of the lighting system 1B as in (a), the difference in electromagnetic wave intensity between it and the surrounding wireless lighting fixtures 30L, 30q, etc., is small, making it difficult to detect errors in the wireless lighting fixture 30r. However, when the terminal device 10B is positioned as... Figure 15 When the device moves to the right side of the lighting system 1B as in (b), although the radio wave intensity of the surrounding wireless lighting fixtures 30L, 30q, etc. increases, the radio wave intensity of the wireless lighting fixture 30r remains weak, thus making it possible to detect an error in the mapping input of the wireless lighting fixture 30r.

[0124] Alternatively, when searching for a wireless lighting device 30r where there is a possibility of an error in the mapping input, the terminal device 10B displays on the display unit 17 the direction in which it should move to cause a difference in the radio wave intensity between the wireless lighting device 30r and the surrounding wireless lighting devices 30L and 30q.

[0125] (Summarize)

[0126] The terminal device 10 according to this embodiment includes: a communication unit 11 that performs wireless communication; a display unit 17 that displays multiple icons 18 corresponding to the positions of each of the multiple wireless lighting devices 30 and the unique addresses ua of each of the multiple wireless lighting devices 30; and a control unit 15 that controls the communication unit 11 and the display unit 17. When the control unit 15 receives a mapping input that associates the icon 18 of a specified wireless lighting device (e.g., 30h) with the unique address ua of the specified wireless lighting device 30h, it compares the communication quality Q1 of the specified wireless lighting device 30h obtained via the communication unit 11 with the communication quality Qr corresponding to the position of the specified wireless lighting device 30h, thereby determining whether there is a possibility of error in the mapping input.

[0127] Therefore, for example, in cases where there is a possibility of an error in the mapping input, the operator can be notified to verify the correctness of the mapping input. This helps to prevent errors in the mapping settings of lighting system 1.

[0128] Alternatively, if the difference between the communication quality Q1 of the specified wireless lighting fixture for 30 hours and the communication quality Qr used for comparison is greater than or equal to a predetermined threshold Qth, the control unit 15 determines that there is a possibility of an error in the mapping input.

[0129] Therefore, the accuracy of determining whether there is a possibility of error in the mapping input can be improved. This, in turn, can suppress errors in the mapping settings of the lighting system 1.

[0130] Alternatively, if the control unit 15 determines that there is a possibility of an error in the mapping input, it may cause the display unit 17 to display a message 19 prompting the reconfirmation of the mapping input.

[0131] In this way, by displaying message 19 prompting a reconfirmation of the mapping input, the operator can be informed of the possibility of an error in the mapping input. This helps to prevent errors in the mapping settings of the lighting system 1.

[0132] Alternatively, if the control unit 15 determines that there is a possibility of an error in the mapping input, it may cause the display unit 17 to display at least one of the icon 18 of the wireless lighting appliance 30 that is likely to have an error in the mapping input and the inherent address ua in a one-view manner.

[0133] Accordingly, the wireless lighting fixture 30 can inform the operator of the possibility of an error in the mapping input. This helps to prevent errors in the mapping settings of the lighting system 1.

[0134] Alternatively, the communication quality Q1 can be the radio wave intensity.

[0135] Therefore, it is possible to determine the likelihood of an error in the mapping input based on the intensity of the electromagnetic wave. Furthermore, if there is a possibility of an error in the mapping input, the operator can be notified to verify its accuracy. This helps to prevent errors in the mapping settings of the lighting system 1.

[0136] Alternatively, the control unit 15 may change at least one of the color, shape, and size of the icon 18 displayed on the display unit 17 based on the difference between the communication quality Q1 value of the specified wireless lighting device 30h obtained via the communication unit 11 and the communication quality Qr value used for comparison.

[0137] Therefore, wireless lighting fixtures can inform operators in an easily understandable way about the possibility of mapping input errors. This helps to prevent errors in the mapping settings of lighting system 1.

[0138] Alternatively, the communication quality Q1 can be the radio wave strength between the wireless access point 41 through which multiple wireless lighting devices 30 communicate and a specified wireless lighting device 30h. The control unit 15 obtains the radio wave strength of the specified wireless lighting device 30h from the wireless access point 41 via the communication unit 11.

[0139] Therefore, it is possible to determine whether there is a possibility of an error in the mapping input based on the radio wave strength obtained from the wireless access point 41. Furthermore, if there is a possibility of an error in the mapping input, the operator can be notified to confirm the correctness of the mapping input. Thus, errors in the mapping settings of the lighting system 1 can be suppressed.

[0140] Alternatively, the communication quality Qr value used for comparison can be determined based on the distance between the wireless access point 41 and the specified wireless lighting fixture 30h.

[0141] In this way, by determining the value of the communication quality Qr used for comparison based on the aforementioned distance, the accuracy of determining whether there is a possibility of error in the mapping input can be improved. Therefore, errors in the mapping settings of the lighting system 1 can be suppressed.

[0142] Alternatively, the communication quality Qr value used for comparison can be determined based on the communication quality Q1 value of the wireless lighting fixtures located in the vicinity of the specified wireless lighting fixture 30h among the multiple wireless lighting fixtures 30.

[0143] In this way, by determining the value of the comparison communication quality Qr based on the communication quality Q1 of the surrounding wireless lighting fixtures, the accuracy of determining whether there is a possibility of an error in the mapping input can be improved. Therefore, errors in the mapping settings of the lighting system 1A can be suppressed.

[0144] Alternatively, the communication quality Q1 can be the radio wave strength between the terminal device 10B, which communicates with multiple wireless lighting devices 30, and the specified wireless lighting device. The control unit 15 determines whether there is a possibility of an error in the mapping input based on the radio wave strength between the multiple wireless lighting devices 30 and the terminal device 10B, which changes as the terminal device 10B moves.

[0145] In this way, by judging the possibility of an error in the mapping input based on the radio wave intensity when the terminal device 10B is moved, a wireless lighting appliance can detect the possibility of an error in the mapping input even when there is no difference in radio wave intensity. Therefore, errors in the mapping settings of the lighting system 1B can be suppressed.

[0146] Alternatively, the terminal device 10 may also include a storage unit 16, which stores the communication quality Qr for comparison. The control unit 15 compares the communication quality Q1 of the specified wireless lighting device 30h obtained via the communication unit 11 with the communication quality Qr stored in the storage unit 16 in advance, thereby determining whether there is a possibility of an error in the mapping input.

[0147] Therefore, it is possible to reliably determine whether there is a possibility of error in the mapping input. As a result, it is possible to suppress errors in the mapping settings of the lighting system 1.

[0148] The lighting system 1 according to this embodiment includes: the terminal device 10 described above; a communication interface 40 that communicates with the terminal device 10; and a plurality of wireless lighting devices 30 that communicate with the communication interface 40.

[0149] According to this lighting system 1, for example, in cases where there is a possibility of an error in the mapping input, the operator can be notified to confirm the correctness of the mapping input. This helps to prevent errors in the mapping settings of the lighting system 1.

[0150] The mapping setting method of the lighting system involved in this embodiment is a method for mapping a lighting system 1 having multiple wireless lighting devices 30 by associating the location information IP of multiple wireless lighting devices 30 with their inherent addresses ua. The mapping setting method includes the following steps: accepting a mapping input that associates the location information IP of a specified wireless lighting device (e.g., 30h) among the multiple wireless lighting devices 30 with the inherent address ua of the specified wireless lighting device 30h; and comparing the communication quality Q1 of the specified wireless lighting device 30h obtained from the outside with the communication quality Qr corresponding to the location of the specified wireless lighting device 30h, thereby determining whether there is a possibility of error in the mapping input.

[0151] According to this method, for example, in cases where there is a possibility of an error in the mapping input, the operator can be notified to confirm the correctness of the mapping input. This helps to prevent errors in the mapping settings of the lighting system 1.
