Further, the configuration shown in FIG. 2 is an example, and the illumination system 100 does not need to have all the configurations shown in FIG. For example, at least one of switch 107 and sensor 108 may not be included in lighting system 100.

[Outline of lighting setting operation]
The illumination setting operation according to this embodiment will be described below. FIG. 3 is a diagram showing a flow of the illumination setting operation according to the present embodiment. This lighting setting operation is large and includes three steps.

First, a lighting designer or the like designs a lighting in advance using a lighting design application (S101). Specifically, the layout of the lighting fixture 102 and the lighting plan (light adjustment, color adjustment, etc.) are created (S111), and the drawing data showing the placement of the lighting fixture 102 and the lighting plan are created (S112).

Next, an electrician or the like performs initial setting of the lighting fixture 102 using the setting application (S102). That is, as shown in FIG. 1, an operator 105 who is an electrician uses a terminal device 104 in a lighting area 101 (store or the like) in which a plurality of lighting fixtures 102 are set, and Make the initial settings.

Specifically, the drawing data created in step S112 is downloaded to the terminal device 104 (S121). Next, using the terminal device 104, setting of logical addresses of the plurality of lighting fixtures 102 (S122), pairing of the lighting fixtures 102 and the controller 103 (S123), and scene setting (S124) are sequentially performed and set. The result is saved (S125).

Finally, the store owner, the person in charge of the office, or the like makes fine adjustments using the operation application (S103). Specifically, fine adjustments such as scene settings (light adjustment and toning settings) are performed on the setting contents saved in step S125 (S131), and the adjusted settings are saved (S132). ).

[Terminal device configuration]
The configuration of the terminal device 104 will be described below. FIG. 4 is a block diagram of the terminal device 104. As shown in FIG. 4, the terminal device 104 includes a communication unit 151, an infrared communication unit 152, and a control unit 153.

The communication unit 151 communicates with the controller 103 by wireless communication, for example. The infrared communication unit 152 performs infrared communication. Specifically, the infrared communication unit 152 transmits an infrared signal to the lighting fixture 102.

The control unit 153 controls the communication unit 151 and the infrared communication unit 152 to perform various setting operations. For example, the function of the control unit 153 is realized by a processor such as a CPU executing a program stored in the memory. The control unit 153 may be configured by a dedicated circuit or may be a combination of these.

The control unit 153 includes an acquisition unit 155, an assignment unit 156, an address setting unit 157, a pairing unit 158, and a setting unit 159.

In addition, the terminal device 104 includes a display unit such as a display that displays an image, and an input unit such as a touch panel that receives a user operation (not shown).

The above function may be incorporated in a single device or may be realized by a plurality of devices. For example, an external infrared module may be used as the infrared communication unit 152, or a dedicated infrared terminal may be used.

[Drawing data download process]
Hereinafter, the setting operation by the worker 105 using the terminal device 104 (S102 in FIG. 3) will be described in detail. At this time, as shown in FIG. 1, although the plurality of lighting fixtures 102 are installed in the lighting area 101, the initial setting is not performed.

First, the worker 105 launches the setting application installed in the terminal device 104. For example, as shown in FIG. 5, the operator 105 logs in by inputting a user name and a password.

Next, a drawing data download process (S121 in FIG. 3) is performed. FIG. 6 is a flowchart of the drawing data download process (S121).

First, the acquisition unit 155 of the terminal device 104 acquires the drawing data created in advance in step S112 from an external server or the like via the network (S141). For example, as shown in FIG. 7, when the operator 105 inputs a file name or a file address in the input field 122 and selects the file selection button 123, the download of the drawing data is started. It should be noted that the user name and the drawing data are associated in advance, and the download of the corresponding drawing data may be started by inputting the user name, or the user name used when logging in is used. The download of the drawing data may be automatically started.

Further, the method of acquiring drawing data is not limited to downloading, and the drawing data may be stored in the terminal device 104 in advance, or the drawing data may be acquired via a recording medium detachable from the terminal device 104. ..

Further, as shown in FIG. 7, of all the processes, progress information 121 indicating which process is currently being executed and which process has been completed is displayed.

FIG. 8 is a screen example after the drawing data is acquired, and is a diagram showing a display example of the drawing data 125. After the drawing data 125 is acquired, the drawing data 125 is displayed. The drawing data 125 is image data showing a state in which the plurality of lighting fixtures 102 are arranged in the illumination area 101. For example, as shown in FIG. 8, symbols 126 (icons) of the plurality of lighting fixtures 102 are displayed on the map data (for example, plan view) of the lighting area 101. The plurality of lighting fixtures 102 are represented by different symbols for each type (for example, product number).

In addition, the drawing data 125 includes the fixture information 127 in which the symbols 126 and the identifiers (for example, product numbers) of the lighting fixtures 102 corresponding to the symbols 126 are listed. Further, the appliance information 127 includes the name of the owner, the construction date, and the like. Note that the project name or the like may be used instead of the owner name, and the opening date or the like may be used instead of the construction date. Further, here, an example in which a product number is used as an identifier of the lighting fixture 102 will be described. However, the identifier is associated with the product number of the lighting fixture 102, and is information that can identify the lighting fixture 102. I wish I had it. The identifier may be, for example, a number or the like for identifying the product number. Further, in addition to the product number of the lighting fixture 102 of each symbol 126, information indicating the type of fixture and the like may be described. Further, the form of the appliance information 127 is not limited to the list display of the symbols 126 and the identifiers of the lighting fixtures 102, and the identifier may be described on each symbol 126 arranged on the map data.

The operator 105 confirms the read drawing data 125, and if there is no problem, selects the confirmation button 128. When reading a different drawing, the change button 129 is selected.

When the confirmation button 128 is selected, the assigning unit 156 of the terminal device 104 acquires the product number of the luminaire 102 used by analyzing the drawing data 125 (S142). The assigning unit 156 also obtains information such as the owner and the construction date by analyzing the drawing data 125. Specifically, the drawing data 125 is image data or a combination of image data and character data. The assigning unit 156 extracts the information on the owner and the construction date, each symbol 126, and the product number corresponding to each symbol 126 by performing image analysis and character authentication on the appliance information 127 in the drawing data 125.

Next, the assigning unit 156 acquires the specifications of the lighting fixture 102 having the acquired product number (S143). For example, a table indicating specifications of each product number is stored in an external server or the like, and the assigning unit 156 acquires the specifications of the lighting fixture of each product number from the server via the network. A table indicating specifications of each product number is stored in the terminal device 104, and the assigning unit 156 may refer to the table stored in the terminal device 104 to acquire the specifications of each product number. . Here, the specifications are, for example, dimming specifications and toning specifications. Note that the specifications may include other information such as the type of lighting fixture (straight tube type/bulb type, LED/fluorescent lamp, etc.), power consumption, and the like.

By the above processing, for example, the appliance information shown in FIG. 9 is acquired. Next, the assigning unit 156 assigns the acquired appliance information (specifications or the like) to the drawing data 125 (S144). Specifically, the assigning unit 156 assigns to each of the plurality of lighting fixtures 102 in the drawing data 125 at least one of the product number and the specification of the lighting fixture 102. In other words, the assigning unit 156 assigns the acquired product number and specifications to each lighting fixture 102 on the drawing data 125. That is, the assigning unit 156 associates each symbol 126 in the drawing data 125 with the product number or the specification of the lighting fixture 102 corresponding to the symbol 126.

FIG. 10 is an example of a screen after information such as specifications is added, and is a diagram showing an example of the drawing data 125 after information such as specifications is added. As shown in FIG. 10, when the lighting fixture 102 (symbol 126) on the drawing data 125 is selected, the addition information 131 including the product number and the spec of the selected lighting fixture 102 is displayed. Further, the information 132 indicating the assigned owner and construction date may be displayed separately from the appliance information 127.

In addition to the owner and the construction date, the number of lighting fixtures 102 may be extracted and information indicating the number may be displayed. Further, the number of units may be extracted and displayed for each product number. For example, the assigning unit 156 extracts the symbols 126 in the drawing data 125 by image analysis and counts the number to extract the number.

As described above, in the present embodiment, the terminal device 104 automatically assigns the drawing data 125 with the product number (identifier) of the lighting fixture 102, specifications, and the like. Thereby, the worker 105 can easily confirm the product number, specifications, and the like of each lighting fixture 102 shown in the drawing data 125 in the terminal device 104, while checking the product number and the specification and the like on the site. As a result, the convenience of the worker 105 can be further improved, and the work time of the setting work can be shortened. Further, it is possible to support the realization of the setting work by the worker 105 who does not have the specialized knowledge.

[Address setting process]
After the completion of the drawing data download process (S121), the address setting unit 157 sets a logical address for each of the lighting fixtures 102 (S122). 11 and 12 are diagrams showing an example of the logical address setting screen.

For example, the worker 105 selects the symbol 126 of the target fixture that is the target lighting fixture 102 for which the address is set, so that the address confirmation information 136 is displayed. The worker 105 confirms the drawing data 125, approaches the target device, points the infrared communication unit 152 of the terminal device 104 toward the target device, and selects the OK button and the send button 135. As a result, the logical address indicated by the address confirmation information 136 is infrared-transmitted to the target device. The target device receives the logical address and holds the received logical address as its own logical address. Next, the worker 105 selects the next symbol 126 and performs the same work to set a logical address to each lighting fixture 102.

Further, as shown in FIG. 12, the symbol 126A of the lighting fixture 102 whose address setting is completed is displayed in a different form from the symbol 126A of the lighting fixture 102 whose address is not set. Thereby, the worker 105 can easily identify the lighting fixture 102 for which the address setting is performed.

When the address setting is completed, the worker 105 selects the completion button 137. The completion button 137 may be displayed when the address setting of all the lighting fixtures 102 is completed.

Further, the logical address transmitted to each lighting fixture 102 may be set in advance and included in the drawing data 125, may be set by the operator 105, or may be automatically set sequentially based on a predetermined rule. It may be set as desired.

Further, instead of the operator 105 selecting the symbol of the target device, the target device may be automatically selected according to a predetermined order.

[Pairing process]
After the completion of the address setting process (S122), the pairing unit 158 performs the pairing process (S123). FIG. 13 is a diagram showing an example of a screen during the pairing process.

In the pairing process, the controller 103 associates the logical address of each lighting fixture 102 with the communication address (physical address). When the wireless adapter 106 is used, the wireless adapter and the lighting fixture 102 are paired. Hereinafter, an example in which a plurality of wireless adapters 106 are used will be described.

First, the pairing unit 158 instructs the controller 103 to execute pairing. The controller 103 instructs each wireless adapter 106 to transmit its own address. The luminaire 102 that has received the address of the wireless adapter 106 returns the address setting process (the logical address of itself set in S122 and the preset communication address to the wireless adapter 106. As a result, the wireless adapter 106 is set. And the lighting fixture 102 are paired.

Further, the logical address and communication address of each lighting fixture 102 are transmitted to the controller 103 via the wireless adapter 106. As a result, the controller 103 associates and manages the logical address and communication address of each lighting fixture 102.

In addition, after the pairing is started, the target device may be determined by turning on/off the power of only the lighting device 102 to be linked. Also, pairing may be performed at the same time when the address is set.

[Scene setting processing]
After the completion of the pairing setting process (S123), the setting unit 159 performs the scene setting process (S124). The setting unit 159 sets a group and a scene in the scene setting process. FIG. 14 is a diagram showing an example of a screen when setting a group.

As shown in FIG. 14, a group is set for a plurality of lighting fixtures 102. For example, a group is set by surrounding the symbols 126 of the lighting fixtures 102 set in the same group with a frame 139. The frame 139 may be set by a method such as tracing with one stroke. Alternatively, after the group is selected, the symbols 126 of the luminaires 102 included in the selected group may be sequentially selected.

Further, the symbol 126 of the lighting fixture 102 for which the group setting is completed may be displayed in a different form from the symbol of the lighting fixture 102 for which the group setting is not performed, such as being surrounded by a frame or changing the background color.

Next, scene setting is performed for each set group. Here, a scene is a setting of dimming and toning, and changing the setting of dimming and toning for each period. 15 and 16 are diagrams showing examples of screens when setting a scene. As shown in FIG. 15, the scene information 141 is displayed. When the worker 105 selects the displayed scene, the setting contents (light control level and color control level) of the scene are displayed. Further, the operator 105 can change the setting contents (light control level and color control level) by operating the setting bar 142.

Further, as shown in FIG. 16, the operator 105 selects a scene boundary to display the scene switching setting. The setting of scene switching is, for example, a switching time which is a transition time when a scene is switched. That is, during the switching time, the dimming level and toning level gradually change from the dimming level and toning level of the previous scene to the dimming level and toning level of the next scene. Further, the operator 105 can change the setting content (switching time) by operating the setting bar 143.

By providing such an interface, the worker 105 can easily confirm and set a group and a scene.

The group and scene settings are set in advance and may be acquired together with the drawing data 125 in step S141. In this case, in this scene setting (S124), the setting content is adjusted, changed or confirmed.

After the scene setting process (S124) is completed, the setting contents are stored in the terminal device 104 and transmitted to the controller 103 (S125). Then, the controller 103 performs lighting control based on the setting contents. FIG. 17 is a diagram showing a screen example when the setting process is completed. For example, a transmission confirmation message 145 as shown in FIG. 17 is displayed, and the worker 105 selects the transmission button 146 to transmit the setting content to the controller 103.

[Effects, etc.]
As described above, in the present embodiment, the worker 105 can install each lighting fixture 102 and adjust the lighting state by using the terminal device 104 such as a tablet terminal. The labor can be reduced.

Furthermore, in the present embodiment, the identification code (for example, product number and specification) of each lighting fixture 102 can be automatically extracted from the drawing data 125. This eliminates the need for the worker 105 to manually input these pieces of information, and thus the labor of the worker 105 can be further reduced. Further, the worker 105 can easily determine the correspondence relationship between the individual lighting fixtures 102 arranged on the ceiling or the like and the lighting fixtures 102 displayed on the terminal device 104 by using the extracted information. This facilitates subsequent processing such as address setting and pairing by the worker 105. In this way, it is possible to realize the illumination system 100 that can easily perform the illumination setting work.

Further, since the lighting setting work is simplified, the setting can be performed even when the worker 105 does not have specialized knowledge of lighting. This eliminates the need for the worker 105 having specialized knowledge to go to the site, so that the work efficiency can be improved.

For example, the present invention may be realized not only as the above lighting system 100 but also as each device (for example, the terminal device 104) included in the lighting system 100, and the characteristic steps performed in the lighting system 100 may be performed. It may be realized as a setting method of the lighting system 100 including the same.

Further, some or all of the processing units included in the lighting system according to the above-described embodiments may be realized as an LSI that is an integrated circuit. These may be individually made into one chip, or may be made into one chip so as to include some or all of them.

Further, the integrated circuit is not limited to the LSI, and may be realized by a dedicated circuit or a general-purpose processor. An FPGA (Field Programmable Gate Array) that can be programmed after the LSI is manufactured, or a reconfigurable processor that can reconfigure connection and settings of circuit cells inside the LSI may be used.

That is, in each of the above-described embodiments, each component may be realized by dedicated hardware or by executing a software program suitable for each component. Each component may be realized by a program execution unit such as a CPU or a processor reading and executing a software program recorded in a recording medium such as a hard disk or a semiconductor memory.
