[motion]
Next, operation of the lighting control system 100 according to the embodiment will be described. FIG. 3 is a sequence diagram showing an example of the operation of the lighting control system 100 according to the embodiment. The operation of FIG. 3 is performed after the plurality of lighting fixtures 10 are installed on the ceiling of the indoor space by the installer. An installer is an example of a user.

First, the operation reception unit 31 of the terminal device 30 receives a start operation for instructing the start of association of the lighting fixtures 10 (S101). FIG. 4 is a diagram showing an example of a screen for accepting a start operation. As shown in FIG. 4 , the operation accepting unit 31 may accept, for example, an operation instructing the start of reading layout information as a start operation instructing the start of association of the lighting fixtures 10 . At this time, the installer inputs an instruction to start association of the lighting fixtures 10 to the operation reception unit 31 by, for example, tapping the "read layout" icon displayed on the display unit 32 of the terminal device 30. .

The control unit 34 acquires layout information indicating the positions of the plurality of lighting fixtures 10 based on the start operation accepted by the operation accepting unit 31 (S102). The layout information is information indicating a top view of the indoor space in which the plurality of lighting fixtures 10 are installed. Here, the layout information is the layout L1 (see FIG. 4), but is not limited to this. For example, the layout information may be coordinate information indicating a predetermined space and a plurality of lighting fixtures 10 installed in the predetermined space, or may be image data such as a layout drawing.

Further, the control unit 34 acquires an image in which at least part of the plurality of lighting fixtures 10 is shown (S103). FIG. 5 is a diagram showing an example of a screen for acquiring an image. As shown in FIG. 5, the installer activates the camera of the terminal device 30 to capture an image A1 in which at least a portion of the plurality of lighting fixtures 10 is captured. Thereby, the control unit 34 acquires an image A1 in which at least a portion of the plurality of lighting fixtures 10 is captured. Also, for example, the control unit 34 may acquire an image A1 captured by an arbitrary camera outside the terminal device 30 . The image may be a still image or a moving image.

The control unit 34 identifies a range within the layout information corresponding to the image A1 acquired in step S103 (S104). Specifically, the control unit 34 identifies a correspondence relationship indicating which range of layout information the image A1 corresponds to. 6 and 7 are diagrams showing examples of screens for identifying the correspondence relationship between the image A1 and the layout information. The layout information is, for example, a layout L1. As shown in FIGS. 6 and 7, the layout L1 acquired in step S102 is displayed in the layout display field 32a of the display unit 32, and the image A1 acquired in step S103 is displayed on the display unit 32. It may be displayed in column 32c.

For example, when the operation reception unit 31 receives the following operation by the installer, the control unit 34 specifies a correspondence relationship indicating which range of the layout L1 the image A1 corresponds to.

The installer performs an operation of designating two points on the layout drawing L1 that define the diagonal of the range corresponding to the image A1. enclosed range). At this time, the installer touches the bottom right corner of the image A1 displayed in the image display field 32c, and then touches one point on the layout drawing L1 displayed in the layout display field 32a. A point on the layout map L1 corresponding to is specified. This point is called a start point SP1 for specifying a range. Next, the installer touches the upper left corner of the image A1 with a finger, and then touches another point on the layout drawing L1 with a finger, thereby touching the point on the layout drawing L1 corresponding to the upper left corner of the image A1. specify. This point is called an end point FP1 of range designation. Note that after the installer touches the lower right corner of the image A1 with a finger and slides the finger from the lower right corner to the upper left corner of the image A1, for example, as shown in FIG. The range may be specified by touching SP1 and sliding a finger from the start point SP1 to the end point FP1. After designating the range, the installer may determine the range by touching an OK button, for example, as shown in FIG.

Next, the control unit 34 sets the effective range in the image A1 (S105). For example, when the operation accepting unit 31 accepts an operation instructing to start setting the effective range, the control unit 34 displays the image A1 on the display unit 32, and sets the range designated by the installer as the effective range. . A valid range is a range that includes valid pixels in the image A1. A valid pixel is a pixel that is used to specify the position of the lighting fixture 10 that is controlled to be turned on or off by the control device 20 .

8 and 9 are diagrams showing examples of screens for setting the effective range in the image. For example, as shown in FIG. 8, the installer inputs an instruction to start setting the effective range to the operation accepting unit 31 by tapping the "specify range" icon. When the operation accepting unit 31 accepts an operation instructing to start setting the effective range, the control unit 34 displays the image A1 on the display unit 32 .

Next, for example, as shown in FIG. 9, the installer selects points P1, P2, P1, P2, P1, P2, P1, P2, P1, P2, P1, P2, P1, P2, P1, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, P2, Specify P3 and P4. At this time, the operation accepting unit 31 accepts an operation of specifying points P1, P2, P3 and P4 on the image A1. Note that the installer may specify the effective range by drawing a trajectory on the image A1 from the point P1, passing through the points P2, P3, and P4, and returning to the point P1.

The installer inputs an instruction to determine the effective range to the operation accepting unit 31 by tapping the “OK” icon. When the operation accepting unit 31 accepts an operation instructing determination of the effective range, the control unit 34 sets the effective range in the image A1. On the other hand, the installer taps the “delete” icon to input an instruction to re-specify the effective range to the operation accepting unit 31 . When the operation accepting unit 31 accepts an operation instructing to re-specify the valid range, the control unit 34 deletes the valid range specified on the image A1.

When the effective range is set, loop processing for each lighting fixture 10 is started (S106). The communication unit 33 of the terminal device 30 transmits a control signal for turning on or off one lighting fixture 10 out of the plurality of lighting fixtures 10 installed in the indoor space in a manner different from that of the other lighting fixtures 10 (S107).

When the control device 20 receives the control signal from the terminal device 30, it selects one lighting fixture 10 (hereinafter referred to as the first lighting fixture) to be controlled from the plurality of lighting fixtures 10 (S108). The control device 20 transmits an instruction signal for turning on or off the first lighting fixture 10 in a manner different from that of the other lighting fixtures 10 (S109). For example, the control device 20 holds identification information of a plurality of lighting fixtures 10, and in step S108, by selecting arbitrary identification information from the identification information, the lighting fixtures 10 selected from the plurality of lighting fixtures 10 are selected. Select one lighting fixture 10 (here, the first lighting fixture) having the identification information. Then, in step S<b>109 , the control device 20 transmits an instruction signal for turning on or off the first lighting fixture 10 in a manner different from that of the other lighting fixtures 10 . At this time, the control device 20 transmits the instruction signal to the plurality of lighting fixtures 10 . Identification information of the first lighting fixture is added to the instruction signal. The lighting fixture 10 to be controlled (here, the first lighting fixture) is turned on or off in a manner different from that of the other lighting fixtures 10 according to the received instruction signal (S110).

Although not shown, the control device 20 may transmit a control signal to the plurality of lighting fixtures 10 and an instruction signal indicating an instruction to acquire an image to the terminal device 30 . Upon receiving the instruction signal, the control unit 34 of the terminal device 30 acquires an image shot with the same composition as the image A1 (S111). The image captured with the same composition as the image A1 is, for example, an image of all the lighting fixtures 10 appearing in the image A1 captured at the same angle and distance as the image A1. For example, a guide (for example, a frame) is displayed on the display unit 32 of the terminal device 30, and the installer takes an image so that some of the plurality of lighting fixtures 10 fit within the displayed guide. Thus, it is possible to shoot an image with the same composition as the image A1.

The control unit 34 of the terminal device 30 determines whether one lighting fixture 10 (hereinafter referred to as the first lighting fixture) controlled by the control device 20 in step S108 is within the effective range of the image A2 (S112 ). FIG. 10 is a diagram showing whether or not the first lighting fixture is reflected within the effective range of the image A2. FIG. 10(a) shows an image A2a that is an example of the image A2 in which the first lighting fixture is reflected within the effective range, and FIG. 10(b) shows the first lighting fixture within the effective range. 2 shows an image A2b, which is an example of an image A2 that does not have an image. For example, as shown in FIG. The identification information of the lighting equipment is requested (S113).

Upon receiving the request for the identification information of the first lighting fixture from the terminal device 30, the control device 20 transmits the identification information of the first lighting fixture to the terminal device 30 (S114).

In step S112, for example, the control unit 34 derives the position of the first lighting fixture in the image A2a based on the pixel information of the image A2a, and based on the correspondence specified in step S104, the first lighting fixture in the layout information. The position of one lighting fixture (in other words, the position of the first lighting fixture in the layout L1) is derived. The pixel information is, for example, at least one of luminance information, illuminance information, and temperature information for each pixel. For example, when the control unit 34 transmits to the control device 20 a control signal for controlling lighting of the first lighting fixture in a manner different from that of the other lighting fixtures 10, the control unit 34, based on the luminance information of the image A2a, The position of one luminaire may be derived. More specifically, the control unit 34 identifies the pixel with the maximum brightness (for example, the pixel positioned at the x mark in FIG. 10A) among the pixels included in the image A2a, and selects the pixel with the maximum brightness. The position of the first lighting fixture in image A2a may be derived based on the position of .

When acquiring the identification information of the first lighting fixture, the control unit 34 of the terminal device 30 associates the acquired identification information with the arrangement position and stores them in the storage unit 35 (S115). FIG. 11 is a diagram showing an example of a screen for associating the identification information of the first lighting fixture with the position of the first lighting fixture in the layout information. For example, as shown in FIG. 11, when the terminal device 30 acquires the identification information of the first lighting fixture, the identification information is displayed in the ID column of the response result display column 32b of the display unit 32. FIG. Further, for example, the position of the first lighting fixture in the layout information (here, the layout L1) is indicated by lighting or coloring the icon of the lighting fixture 10 indicating the first lighting fixture in the layout L1, Furthermore, the coordinate information is displayed in the coordinate field of the response result display field 32b. For example, after confirming that these pieces of information are displayed on the display unit 32, the installer may input a pairing instruction to the operation reception unit 31 by tapping the "pairing" icon. good. When the operation accepting unit 31 accepts an operation instructing the association, the control unit 34 associates the identification information of the first lighting fixture with the position of the first lighting fixture in the layout drawing L1. As a result, after the installer visually confirms that the first lighting fixture has been controlled and that the first lighting fixture is the lighting fixture 10 shown in the image A2a, the identification information of the first lighting fixture and the Since the correspondence with the position can be performed, the correspondence can be performed accurately. Note that the control unit 34 may output the identification information to the control device 20 after associating the identification information of the first lighting fixture with the position in the layout L1. After acquiring the identification information from the terminal device 30, the control device 20 excludes the first lighting fixture from the control targets of step S108.

The control unit 34 determines whether or not the association of all lighting fixtures 10 within the effective range has been completed (S117), and if it is determined that the association has not been completed (No), the process returns to step S107. In step S107, the control unit 34 lights or extinguishes one of the plurality of lighting fixtures 10 other than the first lighting fixture (hereinafter referred to as a second lighting fixture) in a manner different from that of the other lighting fixtures. A control signal for performing control is transmitted to the control device 20 . The control device 20 selects the lighting fixture 10 (here, the second lighting fixture) to be controlled from among the plurality of lighting fixtures 10 (S108), and the second lighting fixture is lit or lit in a manner different from the other lighting fixtures 10. An instruction signal to turn off the light is transmitted (S109). Subsequent steps are performed in the same manner as in the case of the first lighting fixture. On the other hand, in step S117, when the control unit 34 determines that the association of all the lighting fixtures 10 within the effective range has ended (Yes), it transmits a control end command to the control device 20 (S118). Upon receiving the control end command, the control device 20 ends the loop processing for each lighting fixture 10 (S119).

In addition, in step S118, the control unit 34 may transmit the identification information of all the lighting fixtures 10 within the effective range to the control device 20 together with the control end command. Further, for example, in step S118, the control unit 34 may transmit the identification information of all the lighting fixtures 10 within the effective range to the control device 20 instead of the control end command. FIG. 12 is a diagram illustrating an example of a screen for saving correspondence. As shown in FIG. 12, when the association of all the lighting fixtures 10 within the effective range is completed, the installer taps the "save data" icon to display all of the completed associations. An instruction to transmit the identification information of the lighting device 10 to the control device 20 may be input to the operation reception unit 31 . When the operation accepting unit 31 accepts an operation instructing transmission of identification information, the control unit 34 outputs the identification information of all the lighting fixtures 10 within the effective range to the control device 20 . When the control device 20 acquires the identification information from the terminal device 30, the control device 20 excludes the lighting fixture 10 having the identification information from the targets of the lighting or extinguishing control. In this way, after the correspondence is completed for all the lighting fixtures 10 within the effective range, the identification information of the lighting fixtures 10 for which the correspondence has been completed is output to the control device 20, whereby the correspondence of the individual lighting fixtures 10 This improves processing efficiency compared to outputting identification information each time attachment is completed.

On the other hand, in step S112, for example, as shown in FIG. Correspondence is reserved for the lighting equipment (S116). Then, the control unit 34 determines whether or not the association of all lighting fixtures 10 within the effective range has been completed (S117), and if it is determined that the association has not been completed (No), the process returns to step S107. In step S107, the control unit 34 lights or extinguishes one of the plurality of lighting fixtures 10 other than the first lighting fixture (hereinafter referred to as a second lighting fixture) in a manner different from that of the other lighting fixtures. A control signal for control is transmitted to the control device 20, and loop processing for each lighting fixture 10 is performed for the second lighting fixture. On the other hand, in step S117, when the control unit 34 determines that the association of all the lighting fixtures 10 within the effective range has ended (Yes), it transmits a control end command to the control device 20 (S118). Upon receiving the control end command, the control device 20 ends the loop processing for each lighting fixture 10 (S119).

It should be noted that when the loop processing for each lighting device 10 ends in step S119, the process may return to step S103. In this case, the control unit 34 of the terminal device 30 displays an image showing at least some of the lighting fixtures 10 other than the lighting fixtures 10 included in the image A1 among the plurality of lighting fixtures 10 arranged in the indoor space. The range within the acquired layout information (here, the layout drawing L1) corresponding to the acquired image is specified (S104). Next, the control unit 34 sets the effective range in the image (S105), outputs a control start command to the control device 20 (S106), and loop processing (S107 to S119) for each lighting device 10 is executed.

When the operation reception unit 31 of the terminal device 30 receives an end operation instructing the end of the association of the lighting fixtures 10 (not shown), the control unit 34 ends the association processing.

In this way, the lighting control system 100 associates the image A1 in which at least some of the lighting fixtures 10 of the plurality of lighting fixtures 10 appear with the layout drawing L1, and sets the effective area in the image A1. The position of the lighting fixture 10 to be controlled (that is, the first lighting fixture) in the layout L1 can be easily specified. In addition, the lighting control system 100 determines whether or not the lighting fixture 10 to be controlled (that is, the first lighting fixture) is reflected within the effective area. Whether or not it is 10 can be appropriately determined. Therefore, the lighting control system 100 can efficiently associate the identification information with the positions in the layout information for the plurality of lighting fixtures 10 .

[Modification 1 of operation]
In addition, when the control device 20 receives the control signal from the terminal device 30, the control device 20 transmits to the first lighting fixture an instruction signal for turning on or off the first lighting fixture in a manner different from that of the other lighting fixtures. Transmission of the instruction signal to the second lighting fixture may be withheld until a response signal indicating that the instruction signal has been received is received.

As a result, in the lighting control system 100, for example, when the control device 20 cannot smoothly exchange signals with the terminal device 30 and the plurality of lighting fixtures 10 due to a communication failure, the control device 20 arbitrarily proceeds to the next operation. In other words, it is possible to prevent the instruction signal from being transmitted to other lighting fixtures 10 (for example, the second lighting fixture).

[Modification 2 of operation]
When a predetermined time elapses before receiving a response signal indicating that the instruction signal has been received from the first lighting fixture, the control device 20 transmits a cancel signal for canceling the instruction signal to the first lighting fixture. and may further transmit an instruction signal to the second lighting fixture. The predetermined time may be appropriately set by the user.

Thereby, for example, when the communication state with the first lighting device is not good, the lighting control system 100 cancels the control of the first lighting device and controls the second lighting device so that the communication state is good. The pairing can be performed from the lighting fixture 10 that is the same.

[Modification 3 of operation]
The control device 20 may suspend transmission of the instruction signal to the second lighting fixture until it receives a response signal indicating that the identification information of the first lighting fixture has been acquired from the terminal device 30 .

(in other words, the position in the layout plan of the lighting device 10).

As a result, the lighting control system 100 does not need to associate the lighting fixtures 10 that have already been associated by another terminal device 30, so that the lighting fixtures 10 can be associated more efficiently. .

[Effects, etc.]
As described above, the lighting control system 100 includes the control device 20 that controls a plurality of lighting fixtures 10 having unique identification information, and the terminal device 30 that is communicatively connected to the control device 20. The device 30 acquires an image A1 showing at least some of the lighting fixtures 10 among the plurality of lighting fixtures 10, and the acquired image A1 contains layout information (for example, a layout L1) indicating the positions of the plurality of lighting fixtures 10. A control signal is provided to the control device 20 to specify the correspondence relationship indicating which range corresponds, and control the lighting or extinguishing of the first lighting fixture among the plurality of lighting fixtures 10 in a manner different from that of the other lighting fixtures. As a result of control, when it is determined that the first lighting fixture is reflected in the effective range of the acquired image A2a, the identification information of the first lighting fixture is acquired from the control device 20, and the specified response Based on the relationship, the obtained identification information is associated with the position in the layout information (so-called layout drawing L1), and as a result of the control, the first lighting fixture is reflected within the effective range of the obtained image A2b. If it is determined that there is no correspondence, the control signal for performing control to turn on or off the second lighting fixture among the plurality of lighting fixtures 10 in a manner different from the other lighting fixtures is issued. Send to the control device 20 .

The lighting control system 100 as described above associates an image A1 in which at least some of the lighting fixtures 10 of the plurality of lighting fixtures 10 are shown with the layout drawing L1, and further sets an effective area in the image A1. The position of the lighting fixture 10 to be controlled (that is, the first lighting fixture) in FIG. L1 can be easily specified. In addition, the lighting control system 100 determines whether or not the lighting fixture 10 to be controlled (that is, the first lighting fixture) is reflected within the effective area. Whether or not it is 10 can be appropriately determined. Therefore, the lighting control system 100 can efficiently associate the identification information with the positions in the layout information for the plurality of lighting fixtures 10 .

Further, for example, in the lighting control system 100, the terminal device 30 derives the positions of the first lighting fixtures in the images A2a and A2b based on the pixel information of the images A2a and A2b, and the pixel information is luminance information for each pixel. , illuminance information, and temperature information.

Such a lighting control system 100 derives the position of the first lighting fixture in the images A2a and A2b based on one or more information among luminance information, illuminance information, and temperature information for each pixel of the images A2a and A2b. . Therefore, the lighting control system 100 can reduce the influence of noise such as external light or the temperature of the air blown from the air conditioner in deriving the position of the first lighting fixture.

Further, the lighting control system 100 can confirm the determination result as to whether or not the first lighting fixture is reflected in the effective range while confirming the images A2a and A2b and the layout drawing L1. Therefore, the lighting control system 100 can more accurately associate the plurality of lighting fixtures 10 .

Further, for example, in the lighting control system 100, the terminal device 30 outputs the identification information to the control device 20 after associating the identification information of the first lighting fixture with the position in the layout information. When the identification information is obtained from the first lighting fixture, the first lighting fixture is excluded from the control target.

It is possible to efficiently associate a plurality of lighting fixtures 10 .

Further, for example, in the lighting control system 100, when the control device 20 receives the control signal, it transmits to the first lighting fixture an instruction signal for turning on or off the first lighting fixture in a manner different from that of the other lighting fixtures. Transmission of the instruction signal to the second lighting fixture is suspended until a response signal indicating that the instruction signal has been received from the first lighting fixture is received.

In such a lighting control system 100, for example, when the control device 20 cannot smoothly exchange signals with the terminal device 30 and the plurality of lighting fixtures 10 due to a communication failure, the control device 20 arbitrarily proceeds to the next operation. In other words, it is possible to prevent the instruction signal from being transmitted to other lighting fixtures 10 (for example, the second lighting fixture).

Further, for example, in the lighting control system 100, when the control device 20 receives the response signal indicating that the instruction signal has been received from the first lighting fixture, the controller 20 sends the instruction signal to the first lighting fixture after a predetermined time elapses. and a command signal to the second lighting fixture.

Such a lighting control system 100 cancels the control of the first lighting fixture and controls the second lighting fixture, for example, when the communication state with the first lighting fixture is not good, so that the communication state is good. The pairing can be performed from the lighting fixture 10 that is the same.

Also, for example, in the lighting control system 100, the control device suspends transmission of the instruction signal to the second lighting fixture until it receives a response signal indicating that the identification information of the first lighting fixture has been acquired from the terminal device.

In such a lighting control system 100, for example, when the control device 20 cannot smoothly exchange signals with the terminal device 30 and the plurality of lighting fixtures 10 due to a communication failure, the control device 20 arbitrarily proceeds to the next operation. that is, sending an instruction signal to the second luminaire.

Also, for example, the lighting control system 100 includes a plurality of terminal devices 30, and the control device 20 controls the first lighting device until it receives control signals from all of the plurality of terminal devices 30. Transmission of an instruction signal to turn on or off in a manner different from that is suspended.

In such a lighting control system 100, the control device 20 does not start loop processing for each lighting device 10 until all of the plurality of terminal devices 30 are ready. In other words, after all of the terminal devices 30 are ready, the control device 20 starts loop processing for each lighting device 10 . Therefore, it is possible to efficiently associate a plurality of lighting fixtures 10 using a plurality of terminal devices 30 .

Further, for example, in the lighting control system 100, the plurality of terminal devices 30 share identification information of the lighting fixtures 10 and layout information of the lighting fixtures 10 (for example, the layout L1) associated with each other by the other terminal devices 30. share a position in

Since such a lighting control system 100 does not need to associate lighting fixtures 10 that have already been associated by another terminal device 30, it is possible to efficiently associate a plurality of lighting fixtures 10. .

Further, the lighting control method executed by a computer such as the terminal device 30 is a lighting control method executed by the terminal device 30 communicably connected to the control device 20 that controls the plurality of lighting fixtures 10 having unique identification information. The method comprises an acquisition step of acquiring an image A1 in which at least some of the lighting fixtures 10 are shown, and layout information (for example, arrangement A step of specifying a correspondence relationship indicating which range of FIG.
