FIG. 2 is a diagram for explaining exchange of information in a pairing operation including a mapping operation using the mapping device 1. FIG. Referring to FIG. 2, the mapping device 1 is installed in the same section (for example, the same room) controlled by one or more remote controllers (hereinafter simply referred to as remote controllers: parent device, child device) 3. Identification information of each lighting fixture 2 in a plurality of lighting fixtures (plurality of control lighting fixtures) 2 is displayed on the display unit 21 (see FIG. 9) in an arrangement corresponding to the plurality of lighting fixtures 2. The representation 70 (see FIG. 9) is used to map to the corresponding luminaire representation 70 of the representations 70 . Here, the identification information may be any information as long as it is information that can identify each lighting fixture 2 from other lighting fixtures 2. For example, MAC address (Media Access Control address), barcode information, RF (radio frequency) tags, product number information, IP addresses, manufacturing numbers, and the like.

For example, the mapping device 1 uses the transmission unit 24 to transmit an identification information request signal requesting identification information to each lighting fixture 2 via the remote controller 3 . Then, each lighting fixture 2 transmits an identification information containing signal containing identification information, and the mapping device 1 sends the identification information containing signal from each lighting fixture 2 to three access points (hereinafter referred to as APs) first to Receive via three different paths via the third AP 4a-4c. In this embodiment, the case where there are three APs 4a to 4c will be described as an example, but only two APs may exist, or four or more APs may exist. The mapping device 1 maps the identification information of each lighting fixture 2 to the corresponding lighting fixture representation 70 based on the received information. This mapping operation is described in detail below. When the mapping operation is finished, the mapping device 1 uses the transmission unit 24 to transmit the identification information of the lighting fixtures 2 linked to each other by the mapping operation and the information on the corresponding lighting fixture display 70 to the remote controller 3. Then, the linked information is stored in the storage unit of the remote controller 3, and the remote controller 3 can perform dimming control such as group control of the plurality of lighting fixtures 2 based on the linked information. Operation completes.

The mapping operation of the present disclosure will now be described in detail. The mapping operation of the present disclosure uses known RSSI estimation software. Since this RSSI estimation software is publicly known, detailed description will be omitted, but this RSSI estimation software identifies each of the lighting fixtures 2 and each of the APs 4a to 4c based on the signals received by the first to third APs 4a to 4c. Received Signal Strength Indicator (RSSI) of the information-containing signal, ie, the received signal strength of the identification information-containing signal, is estimated as a numerical value indicating the strength of the identification information-containing signal received by the first to third APs 4a to 4c.

In a situation where a plurality of lighting fixtures 2 transmit identification information-containing signals substantially simultaneously, the signals (waves) strengthen and weaken each other, requiring complicated calculations for RSSI estimation. RSSI estimation software performs such calculations. The RSSI for each lighting fixture 2 and for each AP 4a to 4c calculated by this RSSI estimation software is strengthened or weakened between identification information-containing signals (waves), the spatial directivity of the transmission antenna of the lighting fixture 2, and a plurality of There is a problem that it is difficult to reflect the structure of the section where the lighting fixtures are arranged, for example, the presence of a pillar that affects the propagation of radio waves. Therefore, the distance between each lighting fixture 2 and each AP 4a to 4c that can be calculated from the following theoretical formula (1) using RSSI contains an error and deviates from an accurate distance. The RSSI is a value that indicates the distance from each AP 4 a to 4 c to the lighting fixture 2 for each lighting fixture 2 .

R=A-10BLog(RSSI(r)) [dBm] (1)

where, R: RSSI at measurement point [dBm]

A: Radio field intensity [dBm] at 1m from AP

B: Constant in propagation environment (1.0 to 3.0 for non-residential)
r: Distance from AP [m]

In the mapping operation of the present disclosure, multiple anchor fixtures are selected from multiple lighting fixtures 2 based on the RSSI estimated by the RSSI estimation software. Anchor fixtures are, for example, lighting fixtures 2 that are used for mapping of lighting fixtures 2 present in the area around them and whose position is precisely specified.

Anchor devices are determined in the following order: First, a characteristic RSSI is selected from a plurality of RSSIs estimated for each lighting device 2 and each AP 4a-4c. Selection of this characteristic RSSI is performed as follows.

FIG. 3 is an example of a graph showing the RSSI of the identification information-containing signal estimated obtained by each AP 4a-4c for each lighting device 2. In FIG. Referring to FIG. 3, hatched area R1 indicates an area where the distance from APs 4a to 4c is equal to or less than the first predetermined distance. In addition, the one-dot hatched area R2 is the one lighting fixture 2 with the longest distance from each AP 4a to 4c with respect to the plurality of lighting fixtures 2 and the three APs 4a to 4c, and any one of the first to third APs 4a to 4c. In the example shown in FIG. 3, an area with a distance of 35 m or more from each of APs 4a to 4c is shown.

Conversion from each lighting fixture 2 to the distance from APs 4a to 4c can be calculated using the above equation (1). For example, when A=−36 and B=3.0, the distance from the second AP 4b in the lighting fixture 2 corresponding to the RSSI of the measurement point S1 is 0.4 m, which corresponds to the RSSI of the measurement point S2. The distance from the first AP 4a in the lighting fixture 2 is 45 m, and the distance from the third AP 4c in the lighting fixture 2 corresponding to the RSSI of the measurement point S3 is 65 m. Here, regarding the RSSI of the measurement points S2 and S3, the distances from the corresponding APs 4a and 4c of the corresponding lighting fixtures 2 are estimated to be impossible distances in reality. Such estimation of the distance may occur, for example, when there is a pillar or the like between the lighting device 2 and the corresponding APs 4a and 4c, as described above.

Next, the plurality of lighting fixtures 2 are ranked according to the number of APs 4a to 4c whose estimated distances are not within 35m. Specifically, the lighting fixture 2 whose distance to all three APs 4a to 4c is not within 35m is Rank 1, and the lighting fixture 2 whose distance to only two APs 4a to 4c is not within 35m is Rank 2. , and the distance from only one AP 4a to 4c is not within 35 m is classified as rank 3.

The luminaire 2 belonging to rank 1 may be, for example, far from all APs 4a to 4c, or may be located at a unique installation position. Also, a luminaire 2 belonging to rank 2 may be located, for example, at the edge of the mapping area or behind an obstacle. Also, a luminaire 2 belonging to rank 3 may be located, for example, in the direction of the null point of the luminaire or at the edge of the mapping area. Here, the direction of the null point is the direction in which the APs 4a to 4c can receive only very low strength signals due to the directivity of the transmitting antenna of the lighting fixture 2. FIG. Also, lighting fixtures 2 existing within a first distance (for example, 5 m) from any of APs 4a to 4c are classified as rank 4. FIG. In addition, luminaires for which only specific APs 4a-4c received identification information-containing signals are classified as Rank 5.

Then, for example, the identification information of the lighting fixtures 2 is displayed on the display unit 21 of the mapping device 1 in order from rank 1 to rank 5. FIG. More specifically, referring to FIG. 1, the AP distant fixture identification unit 15a counts the number of APs 4a to 4c whose estimated distance is not within 35 m for each lighting fixture 2 based on the RSSI received from each AP 4a to 4c. Calculate to identify lighting fixtures 2 of ranks 1-3.

In addition, the AP peripheral fixture identifying unit 15b identifies the lighting fixtures 2 of rank 4 existing within the first distance (for example, 5 m) from any one of the APs 4a to 4c. Then, when a person (for example, a contractor) uses the operation unit 22 to display the identification information of the lighting fixtures 2 as anchor fixture candidates on the display unit 21, the display order determination unit 15c selects ranks from rank 1 to rank 1. 5, the identification information of the lighting fixtures 2 is displayed on the display unit 21 of the mapping device 1 . Here, the display order determining unit 15c, for example, regarding the ranks 1 to 3, regarding the lighting fixtures 2 of the same rank, (distance from the first AP 4a + distance from the second AP 4b + distance from the third AP 4c) is identified in descending order. The display unit 21 may be controlled so that the information is displayed side by side at predetermined locations on the display unit 21 . Further, the display order determining unit 15c controls the display unit 21 so that, for example, regarding rank 4, the identification information is arranged and displayed in a predetermined position on the display unit 21 in order of decreasing distance to any one of the APs 4a to 4c. good too. Further, the display order determination unit 15c may control the display unit 21 so that, for example, the identification information for the rank 5 is arranged and displayed at a predetermined location on the display unit 21 at random. Each item of identification information displayed on the display unit 21 by the display order determination unit 15c constitutes anchor candidate identification information.

A person sets, for example, about 10% of the number of lighting fixtures 2 as anchor fixtures. In addition, for example, a person selects identification information using the operation unit 22 in the order of the identification information displayed on the display unit 21, and turns on the lighting fixture 2 corresponding to the selected identification information using the operation unit 22. By visually confirming the lighted lighting fixtures 2, a plurality of lighting fixture displays 70 (see FIG. 9) displayed on the display section 21 in a layout corresponding to the plurality of lighting fixtures 2 are displayed using the operation unit 22. ), the selected identification information is mapped to the lighting fixture representation 70 corresponding to the lighting fixture 2 that is lit. The lighting fixture 2 corresponding to the identification information selected by this mapping can be set as the anchor fixture.

It should be noted that, when attempting to turn on the lighting fixture 2 corresponding to the identification information selected using the operation unit 22, none of the lighting fixtures 2 may turn on. This may occur, for example, if the selected identification information is identification information from lighting fixtures other than lighting fixture 2, such as lighting fixtures present on another floor. In such a case, the operation unit 22 is used to erase the selected identification information and select new identification information.

When one lighting fixture 2 is set as an anchor fixture, the operation unit 22 is used to turn off the lighting fixture 2 that was lit when it was set as the anchor fixture. For example, when this procedure is executed for about 10% of the number of identification information of all the lighting fixtures 2 in the order of the displayed identification information, the anchor fixture setting operation is completed.

Next, the mapping work other than the anchoring device will be described. When the anchor fixture setting work is completed, the RSSI of each of the APs 4a to 4c is acquired again using the RSSI estimation software for each of the plurality of lighting fixtures 2 other than the anchor fixture. Here, as described above, since the lighting fixture 2 is set as the anchor fixture in descending order of the number of APs 4a to 4c whose estimated distances are not within 35 m, lighting fixtures with large distance errors from APs 4a to 4c The fixture 2 is out of the RSSI calculation in the RSSI estimation software, and as a result, the estimated distance between the non-anchor lighting fixture 2 and the APs 4a to 4c based on the RSSI estimation software approaches the correct distance.

After that, the person selects one anchor device from the plurality of anchor devices using the operation part 22 . This selection may be performed, for example, as follows. That is, the anchor fixture set in the anchor fixture setting work may be displayed in a color different from that of the lighting fixture not set in the plurality of lighting fixture displays 70 displayed on the display unit 21. And even if a person selects one anchor fixture from a plurality of anchor fixtures simply by touching one lighting fixture display out of the plurality of lighting fixture displays indicating that it is an anchor fixture. good. The lighting fixture display that represents the selected anchor fixture may be displayed in a color that is different from the color of the lighting fixture display that is not set as an anchor fixture and that is also different from the color of the lighting fixture display that represents unselected anchor fixtures. good.

When one anchor device is selected from a plurality of anchor devices, for example, for a plurality of lighting devices 2 other than the anchor devices, the RSSI for the first AP 4a, the RSSI for the second AP 4b, and the RSSI for the third AP 4c are obtained by the following equation (2 ) to (4) are displayed on the display unit 21.

|RSSI for the first AP4a of the selected anchor device−RSSI for the first AP4a|<a (2)

|RSSI for the second AP4b of the selected anchor device−RSSI for the second AP4b|<a (3)

|RSSI for 3rd AP4c of selected anchor device - RSSI for 3rd AP4c|<a (4)

where a is a threshold value that defines the perimeter of the selected anchoring device at a predetermined threshold. Therefore, the lighting fixtures 2 with the identification information displayed on the display unit 21 are a plurality of lighting fixtures 2 other than the anchor fixture, and are positioned around the selected anchor fixture.

A person moves near the actually selected anchoring device and performs a mapping operation of one or more pieces of identification information displayed on the display unit 21 . Here, in the mapping work, similarly to the mapping work of the anchor fixture, the identification information is selected, the lighting fixture 2 corresponding to the selected identification information is turned on, the lighted lighting fixture 2 is visually confirmed, and the lighting fixture is turned on. This is executed by associating the lighting fixture 2 with the corresponding lighting fixture display. Since there is a high possibility that the one or more lighting fixtures 2 corresponding to the one or more pieces of identification information displayed on the display unit 21 are located around the selected anchor fixture, the one or more lighting fixtures 2 corresponding to the one or more pieces of identification information are displayed. lighting fixtures 2 can be efficiently performed.

Thus, when the mapping operation of the lighting fixtures 2 around the selected anchor fixture is completed, another anchor fixture is selected and similar work is performed. The identification information of the lighting fixture 2 mapped by the mapping operation of a certain anchor fixture is not displayed on the display unit 21 when another anchor fixture is selected. When the same operation is performed for all the anchor fixtures and the mapping of the lighting fixtures 2 that are not positioned around the anchor fixtures is completed, the mapping of the lighting fixtures 2 that are not positioned around the anchor fixtures is completed. I do.

The mapping work is performed, for example, as follows. Identification information for which mapping work has not been completed is displayed on the display unit 21 when a predetermined operation is performed using the operation unit 22 . Here, for example, when a person selects one piece of identification information from the displayed pieces of identification information, the lighting fixture 2 corresponding to the selected piece of identification information lights up, and one or more pieces of identification information located around it are displayed. It is designed to be displayed on the part 21 . One or more pieces of identification information located in this vicinity can be identified using equations similar to equations (2) to (4) above.

The difference with (2)-(4) is only to change the 3 RSSI values in the anchor fixture to the 3 RSSI values of the selected luminaire 2 . This operation is repeated until the mapping operation for all lighting fixtures 2 is completed. As described above, for each of the plurality of lighting fixtures 2 other than the anchor fixture, the RSSI for each of the APs 4a to 4c is acquired again using the RSSI estimation software, so the reliability of the estimated distance is increased. It is possible to efficiently perform the mapping operation of lighting fixtures 2 that are not located in the vicinity of the anchor fixture.

As described above, the mapping device 1 includes the receiving unit 23 that receives signals including identification information from the plurality of lighting fixtures 2 via a plurality of APs 4a to 4c and a plurality of different paths. Further, the mapping device 1 selects one of the APs 4a to 4c from among the plurality of lighting fixtures 2 based on the value (RSSI) that is an index of the distance from each of the APs 4a to 4c to the lighting fixture 2 for each lighting fixture 2. One or more lighting fixtures 2 estimated to be within a first predetermined distance from the AP 4a to 4c One or more lighting fixtures 2 estimated to be at least a second predetermined distance from any AP 4a to 4c and a specifying unit that specifies at least one of In this embodiment, the identifying unit is composed of an AP distant instrument identifying unit 15a and an AP peripheral instrument identifying unit 15b. The mapping device 1 also includes a display unit 21 that displays one or more anchor candidate identification information, which is one or more pieces of identification information for the identified one or more lighting fixtures 2 .

Thus, one can use the anchor candidate identification information to set the anchor fixture, and use the anchor fixture to centrally map the lighting fixtures 2 around the anchor fixture. Therefore, mapping can be performed efficiently even if the lighting system to be mapped comprises a large number of lighting fixtures 2, for example several thousand. Furthermore, when one or more lighting fixtures 2 whose distance from any of the APs 4a to 4c is estimated to be at least the second predetermined distance are set as anchor fixtures, the APs 4a to 4c in the lighting fixtures 2 other than the anchor fixtures can approximate the estimated distance to the exact distance. Therefore, the mapping operation can be performed more smoothly.

In addition, the one or more anchor fixtures may be composed only of one or more lighting fixtures 2 estimated to be within the first predetermined distance from any of the APs 4a to 4c. It may be composed only of one or more lighting fixtures 2 that are estimated to be at a distance from the second predetermined distance or more. In addition, the anchor fixture includes one or more lighting fixtures 2 estimated to be within a first predetermined distance from any of the APs 4a to 4c, and a second predetermined distance or more from any of the APs 4a to 4c. It may be configured with one or more lighting fixtures 2 estimated to be.

Further, the second predetermined distance may be set to a value longer than the longest distance between one lighting fixture 2 and one AP 4a to 4c among the plurality of lighting fixtures 2 and the plurality of APs 4a to 4c.

According to this configuration, lighting fixtures 2 whose estimated distances to APs 4a to 4c deviate greatly from the accurate distances to APs 4a to 4c can be excluded from the software calculation for calculating the estimated distances. Therefore, the mapping operation of lighting fixtures 2 other than anchor fixtures can be performed more efficiently.

Further, the mapping device 1 selects one piece of identification information from one or more pieces of identification information displayed on the display unit 21 , turns on the lighting fixture 2 corresponding to the selected identification information, and turns on the lighting fixture 2 . Turning off the lighting fixture 2, mapping the anchor candidate identification information to the corresponding lighting fixture display 70 of the plurality of lighting fixture displays 70 displayed on the display unit 21 in an arrangement corresponding to the plurality of lighting fixtures 2, Excluding the mapped anchor candidate identification information from the calculation of the value that is the index of the distance, and identifying the identification information out of the plurality of lighting fixture displays 70 displayed on the display unit 21 in an arrangement corresponding to the plurality of lighting fixtures 2 may be provided with an operator 22 operable to map to the corresponding luminaire representation 70 of the . According to this configuration, the mapping operation can be performed smoothly.

It should be noted that the present disclosure is not limited to the above embodiments and modifications thereof, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents.

For example, in the above embodiment, the lighting fixture 2 is registered as an anchor fixture in descending order of the number of APs 4a to 4c whose distance from the existing position of the lighting fixture 2 is longer than a predetermined distance. However, the display unit 21 does not have to display the identification information of the anchor device candidates in such order. Specifically, the RSSI values of the lighting fixtures 2 near each AP 4a to 4c, the lighting fixtures 2 positioned around the obstacles, the lighting fixtures 2 far from the APs 4a to 4c, and the lighting fixtures 2 falling into null points based on the antenna directivity is a value greater than the first predetermined value (hereinafter referred to as characteristic value 1 in the specification and drawings) or a value less than the second predetermined value (hereinafter referred to as characteristic value 2 in the specification and drawings) mentioned). Here, FIG. 4, that is, a plan view showing the arrangement of the APs 4a to 4c, the obstacle 50, the lighting fixture 2, and the lighting fixture 2a of the anchor fixture candidate (indicated by hatching in FIG. 4) when viewed from the vertical direction. 2, the control device 10 of the mapping device 1 selects the plurality of lighting fixtures 2 whose RSSI value is the feature value 1 and the plurality of lighting fixtures 2 whose RSSI value is the feature value 2, without determining the order. They may be extracted as anchor candidates and displayed on the display unit 21 .

Accuracy may be improved by interpolating places where there is an error.

Also, as shown in FIG. 6, that is, a plan view corresponding to FIG. 4 in another embodiment, for example, only one AP (for example, the first AP 4a) acquires RSSI, and the other APs (for example, the second AP 4b) If the RSSI data is not acquired, the lighting fixture 2c corresponding to that RSSI is regarded as a lighting fixture on another floor, and is excluded from the anchor fixture candidate lighting fixtures, and its identification information is displayed on the display unit 21. You may choose not to display it.

Also, when a plurality of lighting fixtures 2 are capable of mesh communication and communication between lighting fixtures 2, the relative RSSI of a certain lighting fixture 2 to other lighting fixtures 2 can be estimated. In such a case, as shown in FIG. 7, that is, a plan view corresponding to FIG. 4 in another embodiment, a plurality of anchor fixtures are connected to one of the APs 4a to 4d with a certain lighting fixture 2 as the specific fixture 2d. One or more lighting fixtures 2e corresponding to RSSI with a characteristic value of 1 for both of the specific fixtures 2d, and an RSSI with a characteristic value of 2 for both one of the APs 4a to 4d and the specific fixture 2d. may include one or more lighting fixtures 2f that In this way, the anchor fixture setting is performed in consideration of the communication with the specific fixture 2d in addition to the communication with the APs 4a to 4d, and the lighting fixture 2 from which a more unique RSSI is acquired is registered as the anchor fixture. may

Also, as shown in FIG. 8, that is, a plan view corresponding to FIG. 4 in another embodiment, when a plurality of lighting fixtures 2 are capable of mesh communication and communication between the lighting fixtures is possible, A plurality of lighting fixtures 2 may be classified into a plurality of groups. A plurality of lighting fixtures 2 in each group may have one master fixture 2g as a communication point of contact for communicating with the AP 4. FIG. Then, in each group, at least one of one or more lighting fixtures 2 having an RSSI of characteristic value 1 and one or more lighting fixtures 2 having an RSSI of characteristic value 2 is anchored. You can set it on your device. According to this embodiment, it is easy to arrange a plurality of anchor fixtures spatially evenly with respect to a group of all lighting fixtures 2 . Therefore, mapping operations can be performed more efficiently and without waste.
