(Embodiment)
[Lighting system 1]
FIG. 1 is a schematic diagram illustrating an illumination system 1 according to an embodiment.

As shown in FIG. 1, the lighting system 1 is a system that is installed in a facility such as a house and that can control a plurality of lighting fixtures 30a1 to 30a6 so as to reproduce a lighting scene. In the lighting system 1, for example, when the user utters "lights up with the brightness of XX", the uttered words are subjected to voice recognition processing to light the plurality of lighting fixtures 30a1 to 30a6. Also, the plurality of lighting fixtures 30a1 to 30a6 are connected to an operation unit 130a (sometimes called a wall switch) installed on a construction material such as a wall of the facility, for example, by a two-wire system. A plurality of lighting fixtures 30b1 to 30b6 are connected to an operation unit 130b (sometimes called a wall switch) installed on a construction material such as a wall of a facility, for example, by a two-wire system. The plurality of lighting fixtures 30a1 to 30a6 and the plurality of lighting fixtures 30b1 to 30b6 can also reproduce lighting scenes such as lighting on and lighting off by receiving user's operations on the operation units 130a and 130b. Hereinafter, the plurality of lighting fixtures 30a1 to 30a6 may be collectively referred to as the first lighting fixture 30a, and the plurality of lighting fixtures 30b1 to 30b6 may be collectively referred to as the second lighting fixture 30b.

In the present embodiment, the plurality of lighting fixtures are classified into one or more first lighting fixtures 30a in a first group and one or more second lighting fixtures 30b in a second group. Each first lighting fixture 30a and each second lighting fixture 30b are grouped for each room in the facility. In this embodiment, one or more first lighting fixtures 30a installed in the first room and the first controller 10a constitute a first group, and one or more second lighting fixtures 30b installed in the second room and the second controller 10b constitute a second group. Unless otherwise specified, the first lighting fixtures 30a of the first group and the second lighting fixtures 30b of the second group may be collectively referred to as the lighting fixtures 30, and the first group and the second group may be collectively referred to. It is sometimes simply called a group.

Although the first group and the second group are illustrated in this embodiment, there may be three or more groups. Also, one room may be classified into a plurality of groups.

FIG. 2 is a block diagram illustrating the lighting system 1 according to the embodiment. As shown in FIG. 2, the lighting system 1 includes a first controller 10a, a second controller 10b, one or more first lighting fixtures 30a, and one or more second lighting fixtures 30b.

[controller]
The first controller 10a is a voice input interface that acquires words uttered by users in the facility. The first controller 10a is installed in the first room and can communicate with at least one first lighting fixture 30a and the second controller 10b among the one or more first lighting fixtures 30a that form the first group. and can control each first lighting fixture 30a. The first controller 10a recognizes words uttered by the user and controls each first lighting fixture 30a to reproduce a lighting scene based on the recognized words. User-spoken words are spoken words spoken by the user. Unless otherwise specified, the first controller 10a and the second controller 10b may be collectively referred to simply as controllers.

The first controller 10a has a voice input section 11, a voice recognition section 12, a processing section 13, a storage section 14, a voice output section 15, a first communication section 16, and a power supply section (not shown).

The voice input unit 11 is a microphone or the like that acquires words uttered by the user. The speech input unit 11 converts words uttered by the user into speech signals, and outputs the converted speech signals to the speech recognition unit 12 .

The voice recognition unit 12 performs voice recognition processing on the voice signal acquired from the voice input unit 11 . For example, the speech recognition unit 12 converts the speech signal acquired from the speech input unit 11 into first text information and outputs the first text information to the processing unit 13 .

The processing section 13 selects a control command corresponding to the first text information acquired from the speech recognition section 12 . Specifically, the processing unit 13 determines whether or not the recognized words uttered by the user satisfy a predetermined control condition for causing each of the first lighting fixtures 30a to reproduce the lighting scene. Here, the recognized words uttered by the user mean the first text information indicating the words uttered by the user. The predetermined control condition is a word registered in advance in the storage unit 14 and means second text information including a keyword described later. For example, the control conditions include keywords, which will be described later.

Although one first control command will be described, since there are a plurality of first control commands, there are a plurality of pieces of second text information associated with each first control command. Also, one control command is associated with one or more pieces of second text information. In this way, the processing unit 13 refers to the table in which the second text information and the first control command are linked, and determines whether or not the words (hereinafter referred to as words uttered by the user) satisfy the control conditions. judge. Such a table is stored in the storage unit 14. FIG.

When determining that the word satisfies the control condition, the processing unit 13 selects a first control command corresponding to the word from a plurality of control commands for reproducing the lighting scene. Specifically, when a word satisfies the control condition, the recognized word uttered by the user is a pre-registered word, and the recognized word uttered by the user belongs to the first group and the second group. It is a case where a word specifying one or more groups of is included. Here, the words that specify the group are, for example, words that specify rooms such as "○○ room", "all rooms", "next room", and specific groups such as "group ○○". It is a word etc. to specify. When the user utters a word specifying a group, the processing unit 13 identifies the group to be controlled for which the lighting scene is to be reproduced.

More specifically, when the recognized words uttered by the user are pre-registered words, for example, at least part of the words indicated in the first text information and the words indicated in the second text information. is common, that is, when the recognized user's spoken words contain keywords related to the lighting scene. Here, the keywords related to the lighting scene are, for example, "bright", "dark", "cold", "warm", "sleep", "○○ color", "ON", "OFF", and "lighting". , “lights out”, etc., and are words associated with the execution of lighting scenes, turning on, turning off, and the like. For this reason, everyday conversations not related to lighting scenes, such as "○ and × were fun", are not included in the keywords related to lighting scenes. If the recognized words uttered by the user do not contain the keyword, the processing unit 13 does not make the above determination.

To explain with an example, in a certain group, the first text information in which the user utters "Turn on the room of XX" is the second text information linked to the first control command " Light up the room and have at least some in common. Here, since "lighting" is the keyword, the processing unit 13 determines that the keyword is included in the first text information.

In addition, the case where words specifying a group are included in the recognized words uttered by the user means, for example, the case where the first text information includes words specifying the place where the group to be controlled exists. be.

To explain with an example, since "00 room" included in the first text information is a word that designates a room, that is, a word that designates a group, the processing unit 13 Identifies the group corresponding to the "○○ room" that is to be controlled as the control target. Then, the processing unit 13 determines that the first text information includes a word designating one or more groups.

In this way, the processing unit 13 determines that the first text information "Turn on room XX" satisfies the control condition. Then, the processing unit 13 selects, from a plurality of control commands, a first control command for reproducing a lighting scene corresponding to the first text information "Turn on room XX", and selects the selected first control command. 1 control command is output to the first communication unit 16 .

Here, if the recognized words uttered by the user do not include words specifying groups, the processing unit 13 may specify all groups as objects to be controlled. In this case, the processing unit 13 transmits the selected first control command or second control command to all of the identified groups. You may output to the 1st communication part 16. In this case, lighting fixtures in all groups are lit.

Further, when the recognized words uttered by the user do not include words specifying a group, the processing unit 13 sends the first communication A first control command or a second control command may be transmitted via the unit 16 . In this case, the lighting fixtures of the group to which the controller that acquired the words uttered by the user belongs are lit.

Note that when words satisfy the control condition, not only when the first text information and the second text information match completely, but also when the first text information and the second text information match several tens of percent or more. If so, the words may satisfy the control condition. Further, since "brightness" as a part of the first text information and "brightness" as a part of the second text information are synonymous, the processing unit 13 treats "brightness" as a part of the first text information as a keyword. You can judge.

Further, when the processing unit 13 determines that the word does not satisfy the control condition, it selects the second control command from the plurality of control commands. Specifically, when the words do not satisfy the control condition, at least part of the recognized words uttered by the user are not included in the pre-registered words, that is, the first text information does not include the keyword. This is the case when it is not

For example, when the second text information linked to the control command desired by the user is "turn on room XX", the user utters "that lighting" (first text information). , the second text information does not include the first text information. That is, it is ambiguous what "that" refers to in the first text information. Also, to give another example, it is ambiguous whether "put on" in "put on that" is to turn on a lighting fixture or to attach an object. At this time, the processing unit 13 selects a second control command suitable for the first text information or unrelated to the first text information from the plurality of control commands. The processing unit 13 selects the second control command linked to the extracted second text information. The processing unit 13 outputs the selected second control command to the first communication unit 16 . If the location is ambiguous as described above, the second control command may be sent to all rooms, and only the group to which the user exists, that is, the controller to which the word uttered by the user is input belongs to the second control command. Control commands may be sent.

Here, the second control command is determined in advance according to (1) the control command previously transmitted to the group, (2) the control command with the highest frequency of use among the control commands transmitted to the group, and (3) the time. or (4) a control command determined by default. The processing unit 13 selects the second control command based on the above (1) to (4) having the highest priority.

FIG. 3A is a diagram illustrating history information for selecting a second control command in lighting system 1 according to the embodiment. As shown in FIG. 3A, the processing unit 13 stores the previously transmitted control command (for example, brightness, color temperature, etc. associated with the control command ID) as history information in the storage unit 14 . The processing unit 13 finds the control command transmitted last time by viewing this history information. In addition, the processing unit 13 counts the number of times of use of a plurality of control commands, that is, stores the counted number of times of use of each control command transmitted via the first communication unit 16 in the storage unit 14 as history information. By viewing the history information, the processing unit 13 selects the previously transmitted control command when (1) is set, and selects the frequently used control command when (2) is set. do.

FIG. 3B is a diagram illustrating control commands according to the current time for selecting the second control command in lighting system 1 according to the embodiment. FIG. 3B shows a table of brightness, color temperature, etc., indicated by each control command associated with each predetermined time. When (3) is set, the processing unit 13 reads out from the storage unit 14 a table showing control commands predetermined according to the time indicated by a clocking unit such as a timer (not shown).

FIG. 3C is a diagram illustrating control commands set as defaults for selecting the second control commands in the lighting system 1 according to the embodiment. FIG. 3C shows a table of brightness, color temperature, etc. indicated by the control command. When (4) is set, the processing unit 13 implements this by reading a table indicating control commands predetermined as defaults.

Also, the control commands (1) to (4) are prioritized by the user, for example. For example, when the priorities are set in this order of (1) to (4), the processing unit 13 turns on each of the first lighting fixtures 30a based on the control command (1) with the highest priority. Let When the second control command is selected in this way, the processing unit 13 asks the user by voice, such as "How do you like this kind of lighting?" The processing unit 13 determines whether or not words (responses) uttered by the user include words indicating approval. If the words (responses) uttered by the user include words indicating approval, each of the first lighting fixtures 30a lights up in the lighting scene according to the second control command acquired by the control command in (1). do. However, if the words (responses) uttered by the user do not include words indicating approval, each of the first lighting fixtures 30a is selected based on the next highest priority control command (2). It lights up in the lighting scene according to the control command of 2. In the same way as described above, the processing unit 13 repeats up to (4). Even in (4), if the approval is not obtained from the user, the processing unit 13 may return to, for example, (1) and repeat the same processing, and randomly select the second control command from a plurality of control commands. may

As shown in FIG. 2, the storage unit 14 is a storage device that stores a plurality of control commands and the like executed by the processing unit 13 . The storage unit 14 stores a table in which the second text information and control commands are linked, each count value indicating the number of times each control command is used, a table indicating control commands predetermined according to time, and a default Stores a table or the like showing the determined control commands. Further, the storage unit 14 stores information indicating audio for the audio output unit 15 to output audio.

The voice output unit 15 is a speaker that outputs a voice response to the selected second control command. For example, when the second control command is selected, the audio output unit 15 outputs audio such as "How do you like this kind of lighting?" Note that, for example, when the first control command is selected, the audio output unit 15 may output audio such as "Lights up in the lighting scene of XX."

The first communication unit 16 is a communication module for performing wireless communication with at least one first lighting fixture 30a among the plurality of first lighting fixtures 30a forming the network and the first controller 10a. The first communication unit 16 transmits the first control command or the second control command selected by the processing unit 13 to the network (each of the first lighting fixtures 30a that can communicate). The first communication section 16 is an example of a communication section.

The power supply unit is electrically connected to a commercial power supply, which is an AC power supply. Note that the power supply unit may supply power by using a primary battery or a secondary battery.

In the present embodiment, the second controller 10b constitutes a second group together with each of the second lighting fixtures 30b and is installed in the second room. The second controller 10b can communicate with the first controller 10a and one or more second lighting fixtures 30b and can control each second lighting fixture 30b. Since the configuration of the second controller 10b is the same as that of the first controller 10a, its description is omitted.

When the second controller 10b receives the first control command or the second control command from the first controller 10a, the first communication unit 16 of the second controller 10b receives the received first control command or the second control command. to each second lighting fixture 30b. Since the second controller 10b has the same function as the first controller 10a, the description thereof is omitted.

[lighting equipment]
Each first lighting fixture 30a is installed indoors so as to illuminate the interior of the facility. Power is supplied from a commercial power supply to each first lighting fixture 30a. Each first lighting fixture 30a is installed in the first room and constitutes the first group. Each first lighting fixture 30a can communicate with the first controller 10a.

Each first lighting fixture 30 a has a light emitting module 31 , a lighting control section 32 , a second communication section 34 and a power supply section 33 . Below, each first lighting fixture 30a is a different first lighting fixture 30a, but since they have the same configuration, unless otherwise specified, one first lighting fixture 30a will be described.

The light emitting module 31 emits light for the first lighting fixture 30a to illuminate the surroundings. The light emitting module 31 is a module having an LED (Light Emitting Diode) that radially emits light. The light emitting module 31 has, for example, a light source configured to emit white light, and a mounting board for mounting the light source.

The illumination control unit 32 controls light emitted by the light emitting module 31 . Specifically, the lighting control unit 32 controls lighting of the light emitting module 31 based on the brightness and color temperature indicated by the control command.

The power supply unit 33 is electrically connected to a commercial power supply that is an AC power supply. The power supply unit 33 is a module containing a power supply circuit that supplies power to the light emitting module 31 . The power supply circuit built in the power supply unit 33 converts the alternating current supplied from the wiring connected to the power supply unit 33 into a direct current, and supplies the converted direct current to the light source of the light emitting module 31 via a lead wire. do.

The second communication unit 34 is a communication module that communicates with the first controller 10a. The second communication unit 34 acquires control commands from the first controller 10a. Further, the second communication unit 34 may transmit the received control command to other first lighting fixtures 30a by broadcasting or unicasting.

In the present embodiment, each second lighting fixture 30b forms a second group together with the second controller 10b and is installed in the second room. At least one second lighting fixture 30b is capable of communicating with the second controller 10b. Since the configuration of the second lighting fixture 30b is the same as that of the first lighting fixture 30a, the description thereof will be omitted.

When the second controller 10b receives the first control command or the second control command from the first controller 10a, the first communication unit 16 of the second controller 10b receives the received first control command or the second control command. to each second lighting fixture 30b. Since the second controller 10b has the same function as the first controller 10a, the description thereof is omitted.

[motion]
Next, the operation of the lighting system 1, the control method of the lighting system 1, and the program will be described.

FIG. 4 is a sequence illustrating an operation in the lighting system 1 according to the embodiment when a word uttered by the user satisfies a predetermined control condition for causing lighting fixtures of each group to reproduce a lighting scene. It is a diagram.

As shown in FIG. 4, first, the first controller 10a recognizes words uttered by the user (S10). Specifically, for example, when the user utters "turn on all rooms", the voice recognition unit 12 converts the voice signal "turn on all rooms" acquired from the voice input unit 11 into first text information. and output to the processing unit 13.

When the processing unit 13 acquires the first text information from the voice input unit 11, it determines whether the words satisfy the control condition. Here, in the first text information, "lighting" is a keyword, and "all rooms" is a word specifying a group. That is, the processing unit 13 recognizes the keyword and the designation of the group (S11). Therefore, since the words uttered by the user satisfy the control condition, the processing unit 13 selects the first control command corresponding to the first text information from the plurality of control commands, and the selected first control command. is specified (S12). In this embodiment, the destination groups are the first group and the second group. The processing unit 13 outputs the selected first control command to the first communication unit 16 . In addition, after outputting the first control command to the first communication unit 16, the processing unit 13 outputs a sound indicating that the lighting scene is being executed, such as "Turn on in the lighting scene of XX." may

The first communication unit 16 transmits the selected first control command to the specified group (each first lighting device 30a of the first group and the second controller 10b of the second group) (S21a ).

Upon receiving the first control command, each first lighting fixture 30a lights in the lighting scene indicated by the first control command (S31a).

The second controller 10b, upon receiving the first control command from the first controller 10a, transmits the first control command to each of the second lighting fixtures 30b forming the second group (S21b).

Upon receiving the first control command, each second lighting fixture 30b lights 31b in the lighting scene indicated by the first control command. The lighting system 1 then ends this process.

FIG. 5 illustrates the operation in the lighting system 1 according to the embodiment when the words uttered by the user do not satisfy the predetermined control conditions for causing the lighting fixtures of each group to reproduce the lighting scene. It is a sequence diagram. Note that the description of the same processing as in FIG. 4 will be omitted.

As shown in FIG. 5, first, the first controller 10a recognizes words uttered by the user (S10). Specifically, for example, when the user utters “that lighting”, the voice signal of “that lighting” acquired from the voice input unit 11 is converted into the first text information by the voice recognition unit 12 and sent to the processing unit 13. Output.

When the processing unit 13 acquires the first text information from the voice input unit 11, it determines whether the words satisfy the control condition. Here, it is ambiguous whether "that" included in the first text information indicates a group or a lighting scene. Therefore, since the words do not satisfy the control condition, the processing unit 13 selects the second control command from the plurality of control commands, and specifies the destination group to which the selected second control command should be transmitted. (S112). The processing unit 13 selects the second control command based on any of the above (1) to (4). The processing unit 13 outputs the second control command selected in step S112 to the first communication unit 16. FIG. In this embodiment, the destination groups are the first group and the second group. The processing unit 13 outputs the selected second control command to the first communication unit 16 . In addition, after outputting the second control command to the first communication unit 16, the processing unit 13 outputs a sound indicating that the lighting scene is being executed, such as "Room XX is lit." 15 may be output.

The first communication unit 16 transmits the selected second control command to the identified groups (first group and second group). Specifically, the first communication unit 16 transmits the second control command to each of the first lighting fixtures 30a and the second controller 10b (S22a).

Upon receiving the second control command, each first lighting fixture 30a lights in the lighting scene indicated by the second control command (S31a). Also, upon receiving the second control command from the first controller 10a, the second controller 10b transmits the second control command to each of the second lighting fixtures 30b forming the second group (S22b). Each of the second lighting fixtures 30b, upon receiving the second control command, lights in the lighting scene indicated by the second control command (S31b).

Further, when the second control command is selected, the processing unit 13 extracts voice information such as "How do you like this kind of lighting?" That is, the first controller 10a outputs a question to the user regarding the proposed lighting scene (S14).

When the user responds to the question, the uttered words that the user responds to are input to the first controller 10a (S15). For example, when the user responds “No!”, a voice signal corresponding to the response is input to the processing section 13 via the voice input section 11 and the voice recognition section 12 . Note that the process may be terminated when there is no response from the user for a certain period of time.

The processing unit 13 determines whether the words uttered by the user include words indicating approval. Since the words uttered by the user do not include words indicating approval in "No!", the processing unit 13 determines that the words indicating approval are not included (S16).

The processing unit 13 selects the second control command based on the control command with the next highest priority among the control commands set with the highest priority among the above (1) to (4) (S17). . The processing unit 13 transmits the second control command selected in step S17 to each of the first lighting fixtures 30a and the second controller 10b (S23a).

Upon receiving the second control command, each first lighting fixture 30a lights in the lighting scene indicated by this second control command (S33).

Also, upon receiving the second control command from the first controller 10a, the second controller 10b transmits the second control command to each of the second lighting fixtures 30b forming the second group (S23b). Upon receiving the second control command based on the control command with the next highest priority, each of the second lighting fixtures 30b lights in the lighting scene indicated by the second control command (S31c). In this manner, the lighting system 1 repeats the processing of steps S14 to S17, S23a, S23b, and S31c until approval is obtained from the user. The lighting system 1 then ends this process.

FIG. 6 is a flow chart illustrating the operation of the controller in the lighting system 1 according to the embodiment. Note that description of the same processing as in FIGS. 4 and 5 will be omitted. Although the first controller 10a will be described as an example in FIG. 6, the same applies to the second controller 10b.

As shown in FIG. 6, first, the first controller 10a recognizes words uttered by the user (S10).

The processing unit 13 determines whether the word satisfies the control condition (S122). Specifically, it is determined whether or not the first text information includes a keyword related to the lighting scene and includes words specifying one or more groups. For example, the word “light up all rooms” indicated in the first text information includes the word “light up” as a keyword and the word “all rooms” specifying a group. Therefore, the words uttered by the user satisfy the control condition.

If the word satisfies the control condition (Yes in S122), the first control command for reproducing the lighting scene according to the first text information is selected from the plurality of control commands (S12).

The first communication unit 16 transmits the selected first control command to each of the first lighting fixtures 30a of the first group, which is "all rooms", and the second controller 10b of the second group (S21). . Upon receiving the first control command, each first lighting fixture 30a lights in the lighting scene indicated by the first control command. Also, when the second controller 10b of the second group receives the first control command, it turns on each of the second lighting fixtures 30b according to the first control command. The lighting system 1 then ends this process.

If the words do not satisfy the control condition (No in S122), the second control command is selected from the plurality of control commands (S112). For example, the word "lit like that" indicated in the first text information includes the word "lit" and the word "like that" as keywords. It's unclear what "that way" refers to. In this case, the processing unit 13 may determine that the recognized words uttered by the user do not include words specifying groups, and may specify all groups as control targets. Moreover, even if the processing unit 13 determines that the recognized words uttered by the user do not include words specifying a group, and identifies the group to which the controller that acquired the words uttered by the user belongs to as a control target. good.

The first communication unit 16 transmits the selected second control command to each of the first lighting fixtures 30a and the second group, for example "all rooms" (S22). Upon receiving the second control command, each first lighting fixture 30a lights in the lighting scene indicated by the second control command. Also, when the second controller 10b of the second group receives the second control command, it lights each of the second lighting fixtures 30b in the lighting scene indicated by the second control command.

The first controller 10a outputs a question to the user regarding the proposed lighting scene, for example, "How do you like this lighting?" (S14).

When the user responds to the question, the uttered words that the user responds to are input to the first controller 10a (S15). The spoken word input to the first controller 10a becomes the first text information.

The processing unit 13 determines whether the words uttered by the user include words indicating approval (S116).

If the first text information in step S15 includes words indicating approval in the words uttered by the user (YES in S116), each of the first lighting fixtures 30a and each of the second lighting fixtures 30b will lights up in a lighting scene according to the control command. For example, words indicating approval are "Yes", "OK", and the like. The lighting system 1 then ends the process.

On the other hand, if the words uttered by the user in the first text information in step S15 do not include words indicating approval (NO in S116), it means that approval has not been obtained from the user.

Based on the above (1) to (4), the processing unit 13 selects the second control command with the next highest priority (S17). The control command with the next highest priority is, for example, the control command with the second highest priority among the priorities of the control commands set in the order of (1) to (4). It is a control command.

The processing unit 13 transmits, via the first communication unit 16, the second control command selected based on the control command (2) having the next highest priority to each of the first lighting fixture 30a and the second lighting fixture 30a. It is transmitted to the controller 10b (S23). Thereby, each of the first lighting fixtures 30a and each of the second lighting fixtures 30b are lit in the lighting scene according to the second control command. Then, the lighting system 1 returns to step S14 and performs the same processing.

[Effect]
Next, the effects of the lighting system 1, the control method of the lighting system 1, and the program according to the present embodiment will be described.

As described above, the lighting system 1 according to the present embodiment can communicate with one or more first lighting fixtures 30a, one or more second lighting fixtures 30b, and one or more first lighting fixtures 30a. A first controller 10a, which forms a first group together with one or more first lighting fixtures 30a, can communicate with the first controller 10a and one or more second lighting fixtures 30b, and one or more second lighting fixtures 30b. and a second controller 10b forming a second group together with each other, each of the first controller 10a and the second controller 10b having a plurality of controls for reproducing the lighting scene based on the recognized words uttered by the user. A control command is selected from the commands, one or more groups to be controlled among the first group and the second group are specified, and the selected control command is transmitted to the specified one or more groups.

According to this, each of the first controller 10a and the second controller 10b transmits a selected control command to one or more groups to be controlled based on the recognized words uttered by the user. Thus, the user can control lighting fixtures for each of one or more networked groups in another room, not just the room in which the user is staying.

Therefore, in this lighting system 1, each lighting fixture installed in a room different from the room in which the user is present can be controlled by interacting with the controller. As a result, the user can control each lighting fixture installed in another room while staying in one room, which is highly convenient.

Further, the control method of the lighting system 1 according to the present embodiment can communicate with one or more first lighting fixtures 30a, and the one or more first lighting fixtures 30a and the first controller 10a constitute the first group. and can communicate with the first controller 10a and one or more second lighting fixtures 30b, and the one or more second lighting fixtures 30b and the second controller 10b constitute a second group, and the first controller 10a and Each of the second controllers 10b selects a control command from a plurality of control commands for reproducing the lighting scene based on the recognized words uttered by the user; identifying one or more groups to be controlled and transmitting the selected control command to the identified one or more groups.

Further, the program according to the present embodiment causes a computer to execute the control method of the lighting system 1 .

The lighting system 1, the control method of the lighting system 1, and the program also have the same effects as described above.

Further, in the lighting system 1 according to the present embodiment, each of the first controller 10a and the second controller 10b is configured so that the recognized words uttered by the user are used to reproduce the lighting scene for one or more groups. By determining whether or not a predetermined control condition is satisfied, when it is determined that the word satisfies the control condition, a first control command is selected from a plurality of control commands for reproducing a lighting scene corresponding to the word. If it is determined that the word does not satisfy the control condition, the processing unit 13 selects the second control command from the plurality of control commands, and the first control command selected by the processing unit 13 is added to the specified one or more groups. and a first communication unit 16 that transmits a control command or a second control command.

According to this, it is determined whether or not a recognized word uttered by the user satisfies a predetermined control condition, and if the control condition is not satisfied, the second control command is selected from a plurality of control commands. . Therefore, even if the controller contains words that are not installed in the controller, each lighting fixture can be lit in some lighting scene by executing the selected second control command. That is, the controller can make a suggestion to the user to turn on each lighting fixture in some lighting scene.

Therefore, the lighting fixture can be controlled even if the words uttered by the user are not registered. As a result, it is possible to simplify the user's trouble of rephrasing correctly, so that the lighting system 1 is highly convenient.

In addition, in the lighting system 1 according to the present embodiment, when words specifying a group are included in recognized words uttered by the user, the processing unit 13 identifies the specified group as a control target. Then, the first communication unit 16 transmits the first control command or the second control command selected by the processing unit 13 to the specified group.

According to this, it is possible to control each lighting fixture in the group specified by the user's speech. Therefore, the user can easily control each lighting fixture for each room.

In addition, in the lighting system 1 according to the present embodiment, when the recognized words uttered by the user do not include words specifying groups, the processing unit 13 identifies all groups as objects to be controlled. Then, the first communication unit 16 transmits the first control command or the second control command selected by the processing unit 13 to all the identified groups.

According to this, each lighting fixture in all groups can be controlled simply by speaking for reproducing the lighting scene of each lighting fixture whose location is not specified. Therefore, there is no need for the user to speak to the controllers installed in all the rooms.

Further, the controller can be used as a substitute for the operation units 130a and 130b described above, so that it can control lighting, extinguishing, etc. of each lighting fixture for each group according to user's speech. Therefore, the illumination system 1 is highly convenient.

For example, in the lighting system 1 according to the present embodiment, if the recognized words uttered by the user do not include words specifying a group, the processing unit 13 determines whether the controller that acquired the words uttered by the user belongs to Sending the first control command or the second control command to the lighting fixtures of the group.

According to this, by simply uttering an utterance to reproduce the lighting scene of each lighting fixture whose location is not specified, the controller that has acquired the words uttered by the user can control each lighting fixture in the group to which it belongs. can be done. That is, it controls only each lighting fixture in the group to which the controller whose voice the user is heard belongs. Therefore, even if the user utters vague words that do not specify the location, the lighting system 1 is highly convenient because each lighting fixture is controlled.

Further, in the lighting system 1 according to the present embodiment, the case where the word does not satisfy the control condition is the case where the word is not included in the words registered in advance as the control condition.

According to this, the first control command or the second control command is selected depending on whether the words uttered by the user are included in the pre-registered words. Therefore, each lighting fixture can be reliably controlled without registering more words in the controller.

In addition, in the lighting system 1 according to the present embodiment, a case where words satisfy the control condition is a case where the recognized words uttered by the user include a keyword related to the lighting scene. Then, if the recognized language of the user's utterance does not include the keyword, the processing unit 13 does not make the determination.

According to this, even if the user speaks something without intending to control each lighting fixture, the controller does not show any reaction to this speech and does not control each lighting fixture. Therefore, it is possible to prevent each lighting fixture from being controlled against the user's intention. Also, if the keyword is included in the user's uttered words, desired control can be performed on each lighting fixture.

Further, in the lighting system 1 according to the present embodiment, each of the first controller 10a and the second controller 10b further selects the second control command, transmits the second control command, and then asks the question by voice. is provided.

According to this, it is possible to ask the user whether the lighting scene according to the second control command suits the user's taste. Thereby, the user can approve by utterance if the user likes it, and can reject it by utterance if it does not suit his or her taste. Therefore, the lighting system 1 can bring the user's favorite lighting scene closer.

Further, in the lighting system 1 according to the present embodiment, the second control command is the control command previously transmitted to the plurality of lighting fixtures, the control command having the highest frequency of use among the control commands transmitted to the plurality of lighting fixtures. , a control command that is predetermined according to time, and a control command that is selectively determined from control commands that are determined by default.

According to this, if the second control command is set based on the control commands (1) to (4) described above, the lighting system 1 lights each lighting fixture in a lighting scene suitable for the user. can be made
