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

As shown in FIG. 1, the lighting system 1 is a system installed in a room of a facility such as a house and capable of controlling a plurality of lighting fixtures 30a1 to 30a6 so as to reproduce an illumination scene. In the illumination system 1, for example, when the user utters “lights with a brightness of xx”, the words of the utterance are subjected to voice recognition processing, and the plurality of lighting fixtures 30a1 to 30a6 are turned on. The plurality of lighting fixtures 30a1 to 30a6 are connected to an operation unit 130a (sometimes called a wall switch) installed on a building material such as a wall of a facility by, for example, a two-wire cable. The plurality of lighting fixtures 30b1 to 30b6 are connected to an operation unit 130b (which may be referred to as a wall switch) installed on a building material such as a wall of a facility by, for example, a two-wire cable. 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 and extinguishing when the operation units 130a and 130b receive an operation by the user. Hereinafter, the plurality of lighting fixtures 30a1 to 30a6 may be collectively referred to as a first lighting fixture 30a, and the plurality of lighting fixtures 30b1 to 30b6 may be collectively referred to as a second lighting fixture 30b.

In the present embodiment, the plurality of lighting fixtures are classified into one or more first lighting fixtures 30a of the first group and one or more second lighting fixtures 30b of the second group. Each of the first lighting fixtures 30a and each of the second lighting fixtures 30b are grouped for each room in the facility, and in the present embodiment, one or more first lighting fixtures 30a installed in the first room. And the first controller 10a form a first group, and the one or more second lighting devices 30b installed in the second room and the second controller 10b form a second group. Unless otherwise specified, the first lighting device 30a of the first group and the second lighting device 30b of the second group may be collectively referred to as the lighting device 30, and the first group and the second group may be collectively referred to. Sometimes it is simply a group.

In addition, in this Embodiment, although the 1st group and the 2nd group are illustrated, three or more groups may exist. Further, 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 spoken by a user in the facility. The first controller 10a is installed in the first room, and is capable of communicating with at least one first lighting fixture 30a and the second controller 10b of the one or more first lighting fixtures 30a forming the first group. Moreover, it is possible to control each of the first lighting fixtures 30a. The first controller 10a recognizes the words uttered by the user and controls each of the first lighting fixtures 30a so as to reproduce an illumination scene based on the recognized words. The words spoken by the user are words spoken by the user. Unless otherwise specified, the first controller 10a and the second controller 10b may be collectively referred to as simply controllers.

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

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

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

The processing unit 13 selects the control command corresponding to the first text information acquired from the voice recognition unit 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 word uttered by the user means the first text information indicating the word uttered by the user. Further, the predetermined control condition is a word registered in advance in the storage unit 14, and means the second text information including a keyword described later. For example, the control condition includes a keyword described later.

It should be noted that although one first control command will be described, there are a plurality of first control commands, and thus there is a plurality of second text information associated with each first control command. Further, one control command is associated with one or more pieces of second text information. As described above, the processing unit 13 refers to the table in which the second text information and the first control command are associated with each other, and determines whether the word (hereinafter, the word uttered by the user) satisfies the control condition. judge. Such a table is stored in the storage unit 14.

When it is determined that the word satisfies the control condition, the processing unit 13 selects the first control command corresponding to the word from the plurality of control commands for reproducing the illumination scene. Specifically, when the words satisfy the control condition, the words uttered by the recognized user are pre-registered words, and the words uttered by the recognized user are included in the first group and the second group. If one or more of the groups include words that specify the group. Here, the words that specify a group are, for example, words that specify a room such as "XX room", "all rooms", and "adjacent rooms", or a specific group such as "XX group". These are words to specify. When the user speaks a word that specifies a group, the processing unit 13 specifies a group that is a control target that should reproduce the illumination scene.

More specifically, the case where the recognized word uttered by the user is a word registered in advance means, for example, at least a part of the words shown in the first text information and the words shown in the second text information. Is common, that is, the words uttered by the recognized user include a keyword related to a lighting scene. Here, the keywords related to the lighting scene are, for example, “bright”, “dark”, “cold”, “warm”, “sleeping”, “○○ color”, “ON”, “OFF”, “lighting”. , “Light off”, and the like, which is associated with execution of a lighting scene, lighting, turning off, and the like. For this reason, everyday conversations that are not related to the lighting scene, such as "Ox was fun," are not included in the keywords related to the lighting scene. When the recognized word uttered by the user does not include the keyword, the processing unit 13 does not perform the above determination.

To explain using an example, in one group, the first text information that the user uttered "light the room of XX" is the second text information "XX of the XX" linked to the first control command. Lighting the room" is at least partly common. Here, since “lighting” is the keyword, the processing unit 13 determines that the first text information includes the keyword.

Further, the case where the word uttered by the recognized user includes a word that specifies a group is, for example, a case where the first text information includes a word that specifies a place where the controlled group exists. is there.

Explaining with an example, since "room of XX" included in the first text information is a word that specifies a room, that is, a word that specifies a group, the processing unit 13 includes the first text information. The group corresponding to "Room of 0" is specified as the control target. Then, the processing unit 13 determines that the first text information includes words that specify 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 a first control command for reproducing an illumination scene corresponding to the first text information, "turn on room 0," from a plurality of control commands, and selects the selected first control command. The control command No. 1 is output to the first communication unit 16.

Here, when the words uttered by the recognized user do not include a word designating a group, the processing unit 13 may specify all groups as control targets. In this case, the processing unit 13 transmits the selected first control command or the second control command in order to transmit the selected first control command or the second control command to all the identified groups. It may be output to the first communication unit 16. In this case, the lighting fixtures of all groups are turned on.

When the recognized words uttered by the user do not include a word that specifies a group, the processing unit 13 performs the first communication with the lighting device of the group to which the controller that has acquired the words uttered by the user belongs. The first control command or the second control command may be transmitted via the unit 16. In this case, the lighting equipment of the group to which the controller that has acquired the words uttered by the user belongs is turned on.

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

In addition, when the processing unit 13 determines that the word does not satisfy the control condition, the processing unit 13 selects the second control command from the plurality of control commands. Specifically, when the word does not satisfy the control condition, at least a part of the word uttered by the recognized user is not included in the pre-registered words, that is, the first text information includes the keyword. If not.

For example, when the second text information associated with the control command desired by the user is “light a room of XX”, the user speaks “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. In addition, as another example, "attach" of "apply" is ambiguous as to whether 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 associated with 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 controller exists, that is, the controller to which the word uttered by the user is input, is set to the second group. Control commands may be sent.

Here, the second control command is determined in advance according to (1) the control command transmitted to the group last time, (2) the control command that is frequently used among the control commands transmitted to the group, and (3) the time. Control command set in (4) control command defined by default. The processing unit 13 selects the second control command based on (1) to (4), which has the highest priority.

FIG. 3A is a diagram exemplifying history information for selecting the second control command in the lighting system 1 according to the embodiment. As shown in FIG. 3A, the processing unit 13 stores the control command transmitted last time (for example, the brightness and color temperature associated with the control command ID) in the storage unit 14 as history information. The processing unit 13 determines the control command transmitted last time by browsing the history information. Further, the processing unit 13 counts the number of times of use of the plurality of control commands, that is, stores the 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 browsing the history information, the processing unit 13 selects the control command transmitted last time when (1) is set, and selects the control command which is frequently used when (2) is set. To do.

FIG. 3B is a diagram illustrating a control command according to the current time for selecting the second control command in lighting system 1 according to the embodiment. In FIG. 3B, a table of brightness, color temperature, etc. indicated by each control command associated with each predetermined time is shown. When (3) is set, the processing unit 13 realizes by reading from the storage unit 14 a table indicating a control command that is predetermined according to the time indicated by a timer unit (not shown).

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

Further, the control commands of the above (1) to (4) are prioritized by the user, for example. For example, when the priorities are set in this arrangement order of (1) to (4), the processing unit 13 lights each of the first lighting fixtures 30a based on the control command of (1) having the highest priority. Let In this way, when the second control command is selected, the processing unit 13 asks the user a voice question such as "How about such a light?". The processing unit 13 determines whether the word (response) uttered by the user includes a word indicating approval. If the word (response) uttered by the user includes a word indicating approval, each of the first lighting fixtures 30a lights up in the lighting scene corresponding to the second control command acquired by the control command of (1). To do. However, if the word uttered by the user (response) does not include the word indicating approval, each of the first luminaires 30a is selected based on the control command of (2) having the next highest priority. It lights up in the lighting scene according to the control command of 2. Thereafter, in the same manner as described above, the processing unit 13 repeats until (4). Even in (4), if the user does not obtain the approval, for example, the processing unit 13 may return to (1) and repeat the same processing, and randomly select the second control command from the plurality of control commands. May be.

As shown in FIG. 2, the storage unit 14 is a storage device in which a plurality of control commands executed by the processing unit 13 are stored. The storage unit 14 is a table in which the second text information and the control command are associated with each other, each count value indicating the number of times each control command is used, a table indicating a control command predetermined according to time, and as a default. It stores a table or the like showing the determined control commands. The storage unit 14 also stores information indicating a voice for the voice output unit 15 to output a voice.

The voice output unit 15 is a speaker that outputs a voice response according to the selected second control command. For example, when the second control command is selected, the voice output unit 15 outputs a voice such as "How would you like this?" Note that the voice output unit 15 may output a voice such as “lights in lighting scene of XX.” when the first control command is selected, for example.

The first communication unit 16 is a communication module for performing wireless communication with at least one first lighting device 30a of the plurality of first lighting devices 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 communicable first lighting fixture 30a). The first communication unit 16 is an example of a communication unit.

The power supply unit is electrically connected to a commercial power supply that is an AC power supply. 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 second lighting fixture 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. The configuration of the second controller 10b is the same as that of the first controller 10a, and thus 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 first control command or the second control command. Is transmitted to each second lighting device 30b. The second controller 10b also has the same operation as the above-described first controller 10a, and thus the description thereof will be omitted.

[lighting equipment]
Each 1st lighting fixture 30a is installed in a room so that the room of a facility can be illuminated. Electric power from a commercial power supply is supplied to each of the first lighting fixtures 30a. Each 1st lighting fixture 30a is installed in the 1st room, and comprises a 1st group. Each first lighting fixture 30a can communicate with the first controller 10a.

Each 1st lighting fixture 30a has the light emission module 31, the lighting control part 32, the 2nd communication part 34, and the power supply part 33. In the following, each of the first lighting fixtures 30a is a different first lighting fixture 30a, but since each has the same configuration, one first lighting fixture 30a will be described unless otherwise specified.

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 substrate for mounting the light source.

The illumination control unit 32 controls the light emitted by the light emitting module 31. Specifically, the illumination control unit 32 controls the lighting of the light emitting module 31 based on the brightness and the 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 including 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 the lead wire. To do.

The second communication unit 34 is a communication module that communicates with the first controller 10a. The second communication unit 34 acquires the control command from the first controller 10a. In addition, the second communication unit 34 may transmit the received control command to another first lighting device 30a by broadcast or unicast.

In the present embodiment, each second lighting device 30b constitutes a second group together with second controller 10b, and is installed in the second room. At least one second lighting fixture 30b is communicable with the second controller 10b. The configuration of the second lighting fixture 30b is similar to that of the first lighting fixture 30a, and thus 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 first control command or the second control command. Is transmitted to each second lighting device 30b. The second controller 10b also has the same operation as the above-described first controller 10a, and thus the description thereof will be 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 exemplifying an operation in the lighting system 1 according to the embodiment when a word uttered by a user satisfies a predetermined control condition for causing each lighting fixture of each group to reproduce a lighting scene. It is a figure.

As shown in FIG. 4, first, the first controller 10a recognizes a word uttered by the user (S10). Specifically, for example, when the user utters “light all rooms”, the voice recognition unit 12 converts the voice signal of “light all rooms” acquired from the voice input unit 11 into the first text information. And outputs it to the processing unit 13.

When the processing unit 13 acquires the first text information from the voice input unit 11, the processing unit 13 determines whether the word satisfies the control condition. Here, in the first text information, “lighting” is a keyword, and “all rooms” is a word designating a group. That is, the processing unit 13 recognizes the keyword and the designation of the group (S11). For this reason, the words uttered by the user satisfy the control condition, and therefore 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 the present 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. After outputting the first control command to the first communication unit 16, the processing unit 13 outputs a voice indicating that the lighting scene such as “lights in lighting scene of XX.” is being executed. May be.

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

Upon receiving the first control command, each of the first lighting fixtures 30a is turned on in the lighting scene indicated by the first control command (S31a).

When the second controller 10b receives the first control command from the first controller 10a, the second controller 10b transmits the first control command to each of the second lighting devices 30b included in the second group (S21b).

Upon receiving the first control command, each of the second lighting fixtures 30b lights up in the lighting scene indicated by the first control command (31b). Then, the illumination system 1 ends this process.

FIG. 5 exemplifies an operation in the lighting system 1 according to the embodiment when the words uttered by the user do not satisfy the predetermined control condition for causing each lighting device 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 is omitted.

As shown in FIG. 5, first, the first controller 10a recognizes a word spoken by the user (S10). Specifically, for example, when the user speaks “that lighting”, the voice recognition unit 12 converts the voice signal of “that lighting” acquired from the voice input unit 11 into the first text information, and then the processing unit 13 receives the text information. Output.

When the processing unit 13 acquires the first text information from the voice input unit 11, the processing unit 13 determines whether the word satisfies the control condition. Here, it is ambiguous whether "that" included in the first text information refers to a group or an illumination scene. For this reason, 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. Yes (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. In the present 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. After outputting the second control command to the first communication unit 16, the processing unit 13 outputs a voice indicating that the lighting scene such as “The room of XX has been turned on.” is being executed by the voice output unit. You may make it output to 15.

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

Upon receiving the second control command, each of the first lighting fixtures 30a is turned on in the lighting scene indicated by the second control command (S31a). In addition, when the second controller 10b receives the second control command from the first controller 10a, the second controller 10b transmits the second control command to each of the second lighting devices 30b included in the second group (S22b). Upon receiving the second control command, each of the second lighting fixtures 30b is turned on in the lighting scene indicated by the second control command (S31b).

When the second control command is selected, the processing unit 13 extracts voice information such as “How would you like this light?” from the storage unit 14 and causes the voice output unit 15 to output the voice information. 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 words uttered by the user are input to the first controller 10a (S15). For example, when the user answers “No!”, a voice signal corresponding to the response is input to the processing unit 13 via the voice input unit 11 and the voice recognition unit 12. Note that the process may be terminated when there is no response from the user for a certain period.

The processing unit 13 determines whether or not the word uttered by the user includes a word indicating approval. Since “No!” does not include the word indicating approval in the words uttered by the user, the processing unit 13 determines that the word indicating approval is not included (S16).

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

Upon receiving the second control command, each of the first lighting fixtures 30a is turned on in the lighting scene indicated by the second control command (S33).

In addition, when the second controller 10b receives the second control command from the first controller 10a, the second controller 10b transmits the second control command to each of the second lighting devices 30b included in 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 is turned on in the lighting scene indicated by the second control command (S31c). In this way, in the lighting system 1, the processes of steps S14 to S17, S23a, S23b, and S31c are repeated until approval from the user is obtained. Then, the illumination system 1 ends this process.

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

As shown in FIG. 6, first, the first controller 10a recognizes a word spoken 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 also includes a word identifying one or more groups. For example, the word "light all rooms" shown in the first text information includes the keyword "light" and the word "all rooms" that specifies a group. Therefore, the words spoken by the user satisfy the control condition.

When the words satisfy the control condition (Yes in S122), the first control command for reproducing the illumination scene corresponding to the first text information is selected from the plurality of control commands (S12).

The 1st communication part 16 transmits the selected 1st control command to each 1st lighting fixture 30a of the 1st group which is "all rooms", and the 2nd controller 10b of the 2nd group (S21). .. Upon receiving the first control command, each of the first lighting fixtures 30a lights up in the lighting scene indicated by the first control command. In addition, when the second controller 10b of the second group receives the first control command, the second controller 10b turns on the respective second lighting fixtures 30b by the first control command. Then, the illumination system 1 ends this process.

When the word does 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 "lights like that" shown in the first text information includes the word "lights up" and the word "like that". It is ambiguous what "like that" refers to. In this case, the processing unit 13 may determine that the words uttered by the recognized user do not include a word designating a group, and may specify all groups as control targets. In addition, the processing unit 13 determines that the recognized words uttered by the user do not include a word that specifies a group, and specifies the group to which the controller that has acquired the words uttered by the user belongs as a control target. Good.

The 1st communication part 16 transmits the selected 2nd control command to each 1st lighting fixture 30a which is "all rooms", and a 2nd group, for example (S22). Upon receiving the second control command, each of the first lighting fixtures 30a is turned on in the lighting scene indicated by the second control command. In addition, when the second controller 10b of the second group receives the second control command, the second controller 10b turns on 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 about the proposed illumination scene, for example, "How about such a light?" (S14).

When the user responds to the question, the words uttered by the user 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 word uttered by the user includes a word indicating approval (S116).

When the first text information in step S15 includes a word indicating approval in the words uttered by the user (YES in S116), each first lighting device 30a and each second lighting device 30b is set to the second It lights up in the lighting scene according to the control command of. For example, the word indicating approval is “Yes”, “OK”, or the like. Then, the lighting system 1 ends the process.

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

The processing unit 13 selects the second control command having the next highest priority based on the above (1) to (4) (S17). The control command with the next highest priority is, for example, the second highest priority is set in the priority order of the control commands set in the order of (1) to (4) above (2). It is a control command.

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

[Effect]
Next, operation effects of the illumination system 1, the control method of the illumination 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 devices 30a, one or more second lighting devices 30b, and one or more first lighting devices 30a, A first controller 10a forming a first group together with one or more first lighting fixtures 30a, and a communication 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, and each of the first controller 10a and the second controller 10b controls a plurality of controls for reproducing an illumination 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 the selected control command to one or more groups to be controlled based on the recognized words uttered by the user. Therefore, the user can control not only the room in which the user is staying, but also each lighting device of one or more groups in which the network is configured in another room.

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 device installed in another room while staying in one room, which is highly convenient.

In addition, the control method of the lighting system 1 according to the present embodiment can communicate with one or more first lighting devices 30a, and one or more first lighting devices 30a and the first controller 10a form a first group. And is communicable with the first controller 10a and the one or more second lighting devices 30b, and the second group is composed of the one or more second lighting devices 30b and the second controller 10b. 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, and selects one of the first group and the second group. Specifying one or more groups to be controlled and transmitting the selected control command to the specified 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 the above.

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

According to this, it is determined whether or not the 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 the plurality of control commands. .. Therefore, even if a word not included in the controller is included, by executing the selected second control command, each lighting fixture can be turned on in some lighting scene. That is, the controller can make a suggestion to the user to turn on each luminaire in some lighting scene.

Therefore, the lighting device can be controlled even if the words spoken by the user are not registered. As a result, it is possible to simplify the trouble of the user to re-word correctly, so that the illumination system 1 is highly convenient.

Further, in lighting system 1 according to the present embodiment, when the recognized words uttered by the user include a word designating a group, processing unit 13 identifies the designated 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 designated group.

According to this, it is possible to control each lighting fixture of the group designated by the user's utterance. Therefore, the user can easily control each lighting device for each room.

Further, in the lighting system 1 according to the present embodiment, when the recognized words uttered by the user do not include a word designating a group, the processing unit 13 specifies all groups as control targets. 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 luminaire in all groups can be controlled only by utterance for reproducing the illumination scene of each luminaire which does not specify a place. Therefore, the user does not need to speak to the controllers installed in all rooms.

In addition, the controller can be a substitute for the above-described operation units 130a and 130b, so that the lighting device can be turned on and off for each group according to the user's utterance. Therefore, the lighting system 1 is highly convenient.

For example, in the lighting system 1 according to the present embodiment, if the recognized words spoken by the user do not include a word designating a group, the processing unit 13 belongs to the controller that has acquired the words spoken by the user. Sending the first control command or the second control command to the lighting equipment of the group.

According to this, the controller that has acquired the words uttered by the user can control each luminaire in the group to which the utterance is reproduced in order to reproduce the lighting scene of each luminaire that does not specify the location. You can That is, it controls only each of the lighting devices of the group to which the controller that the user's voice is heard belongs. For this reason, even if the user speaks an ambiguous word that does not specify the location, each lighting fixture is controlled, and thus the lighting system 1 is highly convenient.

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

According to this, the first control command or the second control command is selected depending on whether or not the word uttered by the user is included in the words registered in advance. For this reason, it is possible to reliably control each lighting fixture without registering more words in the controller.

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

According to this, even if the user makes some utterance without the intention to control each luminaire, the controller does not show any reaction to this utterance and does not control each luminaire. Therefore, it is possible to suppress the control of each lighting device against the user's intention. Further, if the keyword is included in the words spoken by the user, it is possible to perform desired control for 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 by voice. The audio output unit 15 for outputting

According to this, it is possible to ask the user whether or not the lighting scene corresponding to the second control command suits the user's preference. Thus, the user can approve by utterance if he or she likes it, and can reject by utterance if he or she does not like it. Therefore, in the lighting system 1, it is possible to bring the lighting scene closer to the lighting scene desired by the user.

In addition, in the lighting system 1 according to the present embodiment, the second control command is a control command that is used frequently among the control commands that were previously transmitted to the plurality of lighting fixtures and the control commands that were transmitted to the plurality of lighting fixtures. , A control command that is predetermined according to the time of day, 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 above-mentioned control commands (1) to (4), the lighting system 1 turns on each lighting fixture in the lighting scene suitable for the user. Can be made.
