<Operation example of lighting device layout estimation system>
FIG. 6 is a flowchart showing an example of the operation of the lighting device arrangement estimation system 100 according to the embodiment of the present disclosure.

In the lighting device placement estimation system 100, the user sets an initial anchor in step S61. For example, in order to estimate the installation location of each lighting device 210-290, the user selects one or more of the installed lighting devices, and the ID of the selected one or more lighting devices and the string of the installation location. The attachment is visually performed, registered as an initial anchor, and the process proceeds to step S62.

Although not shown in FIG. 6, before step S61, the lighting device 210-290 is mounted on the ceiling, for example, and the connection with the access point 120 is completed (in other words, the formation of the network topology is completed). It is in a state of being.

In step S62, the lighting device arrangement estimation system 100 estimates the positions of the remaining lighting devices not set in the anchor by using, for example, the initial anchor set in step S61, and transitions from step S61 to step S63. For example, the estimation unit 114 of the computer 110 estimates the position of the lighting device excluding the anchor (including the initial anchor and the additional anchor described later) based on the log information received and collected from the log collection unit 124 of the access point 120.

In step S63, the lighting device arrangement estimation system 100 selects and selects one installation location for confirming the association with the ID of the lighting device in order to confirm whether or not the lighting device estimated in step S62 is correct. The candidate ID of the lighting device that may exist at the installation location is displayed. Next, the process transitions to step S64.

In step S64, the lighting device arrangement estimation system 100 turns on the IDs displayed in the candidate lighting device ID list D2 of the display unit 111 in order according to the user's selection. Next, the process transitions to step S65.

In step S65, the lighting device arrangement estimation system 100 determines whether or not the lighting device lit in step S64 and the lighting device at the lighting installation location to be registered match. When the lighting device attached to the selected place is lit (Yes in step S65), the process transitions to step S66, and when the lighting device attached to the selected place is not lit (No in step S65), the process is performed. Transition to step S69.

In step S69, the lighting device arrangement estimation system 100 determines whether all the lighting devices in the candidate lighting device ID list D2 in the display unit 111 have been confirmed (for example, turned on). If all are confirmed (Yes in step S69), the process proceeds to step S67, and if all are not confirmed (lighted) (No in step S69), the process proceeds to step S64.

In step S66, the lighting device arrangement estimation system 100 registers the lighting device whose estimation result matches the lighting device to be confirmed work in association with the position in the light distribution diagram by the registration unit 115. At that time, the registration unit 115 may register the registered lighting device in the additional anchor. After step S66, the process transitions to step S67.

In step S67, the lighting device arrangement estimation system 100 determines whether or not the confirmation work (mapping) of each lighting device excluding the initial anchor has been completed. If it is completed (Yes in step S67), the process proceeds to step S68, and if it is not completed (No in step S67), the process proceeds to step S63.

In step S68, the lighting device arrangement estimation system 100 determines whether or not the association between the IDs of all the lighting devices and the installation location is completed. If it is completed (Yes in step S68), the process is completed, and if it is not completed (No in step S68), the process returns to step S62.

When the additional anchor is registered in step S66, the lighting device arrangement estimation system 100 can improve the position estimation accuracy of the lighting device because the additional anchor is used for the position estimation of the lighting device in the process of step S62 again.

<Detailed explanation of operation>
The operation flow of FIG. 6 will be described in more detail with reference to FIGS. 3 and 7 to 10.

As described above, the lighting device 210-290 is in a state of being attached as shown in the light distribution diagram of FIG.

FIG. 7 is a diagram showing an example of the correspondence relationship between the ID of the lighting device and the installation location according to the embodiment of the present disclosure.

The leftmost column "attached lighting device ID" in FIG. 7 displays the confirmed ID, and the unconfirmed ID is displayed as a blank. The installation locations A1 and A9 indicate the state after being set as the initial anchor.

By referring to the leftmost column “mounted lighting device ID” and the second column “lighting installation location” from the left in FIG. 7, the lighting device 210 is in the light distribution diagram display area D1 in FIG. It can be seen that the lighting device 290 is attached to the installation location A1 and is attached to the installation location A9 in the light distribution diagram display area D1 of FIG.

The lighting device IDs 220, 230, 240, 250, 260, 270, and 280 are linked to any of the installation locations A2, A3, A4, A5, A6, A7, and A8 by the processing described below. Can be attached.

First, the lighting device arrangement estimation system 100 sets the lighting device 210 attached to the installation location A1 and the lighting device 290 attached to the installation location A9 as initial anchors (step S61). In this example, there are two initial anchors, lighting devices 210 and 290, but the number of initial anchors may be one or more.

Next, the lighting device arrangement estimation system 100 estimates the position of each lighting device. The estimation unit 114 assigns a lighting device ID to each installation location for seven lighting devices 220, 230, 240, 250, 260, 270, and 280, excluding the initial anchors 210 and 290 set in step S61. presume.

Lighting devices 240, 230, 220, 250, 260, 280, and 270, respectively, by the estimation unit 114 at the installation locations A2, A3, A4, A5, A6, A7, and A8, as shown in FIG. The result estimated to be located is displayed in the rightmost "estimated result" column. In FIG. 7, one lighting device is displayed as an estimation result for one lighting installation location, but two or more lighting devices may be displayed as an estimation result for one lighting installation location. (See FIGS. 8 and 9 below).

The operation example shown in FIG. 6 will be described in more detail with reference to FIGS. 8 and 9.

FIG. 8 is a diagram showing an example of registration work at the installation location A2 of the lighting device arrangement estimation system 100 according to the present embodiment.

In the work of associating the installation location A2 with the lighting device ID installed in the installation location A2, the lighting devices corresponding to the IDs of the candidate lighting devices 240, 280, 230, 270, and 250 for the installation location A2 are used. Turn on in order. Here, when the lighting devices corresponding to IDs 240 to 250 are turned on in order according to the candidate lighting device ID list D2, the ID 220 of the lighting device 220 actually installed at the installation location A2 is included in the candidate lighting device ID list D2. Therefore, the lighting device 220 installed at the installation location A2 does not light. Therefore, at this stage, the lighting device installed at the installation location A2 is not associated with the ID.

Next, the explanation shifts to the association with the ID of the lighting device at the installation location A3.

FIG. 9 is a diagram showing an example of registration work at the installation location A3 of the lighting device arrangement estimation system 100 according to the embodiment of the present disclosure.

In the work of associating the installation place A3 with the lighting device ID installed in the installation place A3, the lighting devices corresponding to the candidate lighting device IDs 230, 240, 220, 260, and 280 are turned on in order. When ID = 230 is selected in the candidate lighting device ID list D2, the lighting device 230 installed at the installation location A3 lights up (step S65). As a result, the installation location A3 and the lighting device 230 (ID = 230) installed at the installation location A3 are associated and stored. In this case, the lighting device 230 may be further registered in the additional anchor (step S66).

By performing this operation from the installation location A2 to the installation location A8 in order except for the installation location where the initial anchor is registered, for example, the installation location for the lighting device 230, the lighting device 250, and the lighting device 260. Linking is completed.

In order to link the lighting device 240 whose installation location and ID have not been linked in steps S63 to S67 of FIG. 6, the lighting devices 210 and 290 of the initial anchors have been linked to the lighting devices 210 and 290. Re-estimation is performed in step S62 using a total of five anchors in which three devices 230, 250, and 260 are newly added to the anchors.

FIG. 10 is a diagram showing an example of the result of re-estimation of the estimation unit 114 according to the embodiment of the present disclosure.

The results of re-estimation with three additional anchors added to the two initial anchors are shown in the rightmost column "estimation results" in FIG. Since the estimation accuracy is improved by increasing the number of anchors from 2 to 5, unlike the estimation result in FIG. 7, the lighting device ID 220 is installed in the installation location A2, and the lighting device ID 240 is installed in the installation location A4. The lighting device ID 270 is estimated in A7, and the lighting device ID 280 is estimated in the installation location A8.

By performing the confirmation work again from step S63 based on this estimation result, the confirmation of all the lighting device IDs and the installation locations can be completed in step S68, and the associating process is completed.

<Modification of Example>
In the present embodiment, the display unit 111 of the computer 110 displays a list of candidate lighting device IDs at the installation location of the lighting device, and the user correctly estimates the association between the lighting device ID and the installation location. An example of confirming whether or not it is explained has been explained.

On the other hand, the display unit 111 may indicate in which range (not one place) of the lighting distribution diagram the ID of the lighting device exists. This range may include multiple installation locations.

FIG. 11 is a diagram showing an example of a guide display of the display unit 111 according to the embodiment of the present disclosure.

The display unit 111 has, for example, a light distribution diagram read button B1, an anchor registration button B2, an estimation start button B3, a light distribution diagram display area D1 for displaying a light distribution diagram, a lighting device ID list D3, and lighting. A guide D4 (dashed-dotted line), which indicates the possibility that the device may exist, is displayed.

The light distribution diagram read button B1, the anchor registration button B2, the estimation start button B3, and the light distribution diagram display area D1 for displaying the light distribution diagram may all be the same as those in the display unit 111 shown in FIG. ..

The lighting device ID list D3 may include IDs of all lighting devices existing in the lighting device placement estimation system 100. In the case of this example, the lighting device ID 210 to the lighting device ID 290 are the IDs of all the lighting devices.

The estimation unit 114 determines that the lighting device ID selected by the user from the lighting device ID list D3 is in a range in which the lighting device ID may actually exist, and displays the guide D4 (dashed-dotted line) on the display unit 111. For example, when the user selects the lighting device 210 from the lighting device ID list D3, the display unit 111 displays the range in which the lighting device 210 may exist as the guide D4 based on the estimation result of the estimation unit 114. As a result, the user can narrow down the search range, and it is possible to shorten the linking time compared to searching the entire installation location. When linking a large number of lighting devices, the area to be viewed becomes narrower, and the effect of shortening the time is great.

<Supplement>
The communication methods of the communication units 112 and 121 may be a wired communication method such as Ethernet (registered trademark) or power line communication, or a wireless communication method such as wireless LAN (Local Maria Network) or Bluetooth (registered trademark).

A wireless LAN (Local Area Network), WiGig using a millimeter wave band, or a specific low power radio may be applied to the communication method of the wireless units 123 and 211.

As an example of the communication log collected by the log collecting unit 124 or the logger unit 2x2 (x = 1 to 9), the radio wave strength (RSSI (received signal strength display), SNR (signal-to-noise ratio), SINR (signal-to-interference)) Noise ratio)), or packet error rate.

For example, an incandescent lamp, a fluorescent lamp, an LED, or an organic EL may be applied to the light emitting body of the illumination unit 214.

In step S65 of FIG. 6, the user visually confirms whether or not the confirmed portion is lit, but the confirmation of the lit portion may not be visually performed. For example, the corresponding illuminated portion may be photographed by a camera mounted on or connected to the computer 110, and whether or not the illuminated portion is turned on may be determined by image processing.

Although the computer 110 has been described with the configuration including the display unit 111, the computer 110 may not include the display unit 111. For example, the display unit 111 may be included in another device such as a mobile terminal, a tablet terminal, a smartphone, or a mobile phone, which is different from the computer 110. A function different from that of the display unit 111 in the computer 110 may be implemented on the cloud. Alternatively, some or all of the functions of the computer 110 may be implemented in other devices such as mobile terminals, tablet terminals, smartphones, and mobile phones. Further, the access point 120 may be integrally configured with the computer 110. In other words, the computer 110 may have the function of the access point AP120.

<Other position estimation methods>
The method of estimating the position of the lighting device may be a method based on the existence probability of adjacent lighting devices. For example, when the luminaires are attached to the ceiling or wall in a grid pattern at regular intervals, the computer 110 determines the luminaire IDs existing in the individual grids (cells) that divide the installation range of the luminaires into a grid pattern. presume.

For example, the probability that another lighting device is adjacent to each lighting device (adjacent probability) is obtained (adjacent estimation process), and the existence probability of the lighting device in each cell is calculated based on the adjacent probability (mapping process). Specifically, in FIG. 3, the illuminating device adjacent to the illuminating device installed in A1 indicates the illuminating device installed in A2, A4, and A5. Further, the existence probability indicates the probability of existence in each of the installation locations A1 to A9 when focusing on the lighting device 220.

After that, the lighting device and the installation location are associated with each other on a one-to-one basis (matching process). The estimation result may be determined by associating with the installation location in order from the lighting device having the highest existence probability.

In the adjacency estimation process, for example, the probability of adjacency between different lighting devices may be obtained based on the received signal intensity between adjacent lighting devices measured in advance. In the mapping process, for example, the probability that the lighting device exists at each installation location may be obtained based on the probability of adjacency between the lighting devices.

Taking FIG. 3 as an example, the probability that the lighting device 210 exists in each of the installation locations A1 to A9 is obtained. In this case, since the installation location of the lighting device 210 is known, the probability of existing in the installation location A1 is 1, and the probability of existing in the other installation locations A2 to A9 is 0.

In the matching process, for example, the lighting device and the installation location may be associated with each other on a one-to-one basis based on the existence probability of each lighting device obtained in the mapping process.
