JP 2013-145634 A

  By the way, when controlling a plurality of lighting fixtures, not only wireless communication between the lighting fixtures and the terminal device but also direct wireless communication between the lighting fixtures is performed.

Therefore, radio signals having control information may interfere with each other, and the lighting fixture may not be able to receive the control information. In addition, when a user only wants to operate a specific lighting fixture, such as when performing a demonstration of a lighting fixture in a store, the user does not intend that the lighting fixture that has received control information from the terminal device performs multi-hop communication. Even lighting fixtures may work.

A transmission number determination unit to determine, the transmission number determination unit determines the smaller number of transmissions as the first hopping number is smaller, and the transmission unit is determined by the transmission number determination unit The number of transmissions and the transmission of the second information are repeated.

  In order to achieve the above object, a terminal device according to an aspect of the present invention is a terminal device for operating a lighting fixture having a multi-hop function of transferring information received by wireless communication to another lighting fixture. The terminal device includes a mode acquisition unit that receives switching between the normal use mode and the non-normal use mode, an input unit that receives a lighting state of the lighting fixture from a user, a hopping number determination unit that determines the number of hoppings, and the lighting And an output unit that transmits control information including information related to the state and the number of hoppings to the lighting fixture, and the hopping number determination unit is predetermined when the normal use mode is set.

Therefore, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims showing the highest concept of the present invention are described as optional constituent elements.

  Each figure is a mimetic diagram and is not necessarily illustrated strictly. In each figure, substantially the same configuration is denoted by the same reference numeral, and redundant description may be omitted or simplified.

(Embodiment 1)
Hereinafter, the lighting system including the lighting fixture according to the present embodiment will be described with reference to FIGS. In this embodiment, a case where a plurality of lighting fixtures installed indoors is controlled will be described.

[1. Configuration of lighting system]
First, the illumination system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing an overall configuration of a lighting system 1 according to the present embodiment.

  The lighting system 1 according to the present embodiment includes a plurality of lighting fixtures (for example, lighting fixtures 10a and 10b) and a terminal device 60. The plurality of lighting fixtures and the terminal device 60 have a wireless communication function, and the plurality of lighting fixtures change the lighting state based on control information from the terminal device 60. In addition, in FIG. 1, although the example with two lighting fixtures is shown, the number of the lighting fixtures with which the lighting system 1 is provided is not specifically limited, What is necessary is just two or more.

[1-1. lighting equipment]
Next, the structure of the lighting fixtures 10a and 10b which concern on this Embodiment is demonstrated, referring FIG. In addition, in FIG. 1, although the two lighting fixtures 10a and 10b are shown, since each structure is the same, the lighting fixture 10a is mainly demonstrated.

  The lighting fixture 10a is an indoor lighting fixture that is installed indoors and illuminates a space. The lighting fixture 10a is supplied with electric power, and is turned on by the supplied electric power to illuminate the space where the lighting fixture 10a is installed.

  The lighting fixture 10a is, for example, a ceiling light, a spotlight, or a pendant light. The plurality of lighting fixtures may be the same type of light, or may be different types of lights. For example, the lighting fixture 10a may be a ceiling light, and the lighting fixture 10b may be a spotlight.

  As illustrated in FIG. 1, the lighting fixture 10 a includes a wireless communication unit 20, a control unit 30, a light source unit 40, and a storage unit 50.

  The wireless communication unit 20 is a wireless communication interface that performs wireless communication. The wireless communication unit 20 establishes a wireless communication connection with a communication partner apparatus for wireless communication, and then performs wireless communication with the communication partner apparatus. In the present embodiment, the wireless communication unit 20 establishes a wireless communication connection with the terminal device 60 or another lighting device (the lighting device 10b in the present embodiment). The wireless communication unit 20 is an example of a reception unit that receives control information from the terminal device 60, and is also an example of a transmission unit that transmits control information to other lighting fixtures.

  As an example, the wireless communication is wireless communication using a Bluetooth (registered trademark) communication standard. In this case, the wireless communication unit 20 is a communication module (communication circuit) compatible with the Bluetooth (registered trademark) communication standard. Note that the communication standard is not limited to Bluetooth (registered trademark), and may be wireless communication using a communication standard such as a wireless LAN (for example, Wi-Fi (registered trademark)).

  Moreover, although mentioned later for details, the some lighting fixture (for example, lighting fixture 10a, 10b) which concerns on this Embodiment performs multihop communication. Specifically, when the lighting fixture 10a receives control information from the terminal device 60 via the wireless communication unit 20, the lighting fixture 10a wirelessly transmits the control information to the lighting fixture 10b that has not received control information from the terminal device 60. It transmits via the communication unit 20. In other words, the lighting fixture 10a transfers the control information received from the terminal device 60 to the lighting fixture 10b. That is, the lighting fixtures 10a and 10b are lighting fixtures having a multi-hop function, and the lighting fixture 10b receives control information from the terminal device 60 via the lighting fixture 10a. The communication path of multi-hop communication is a mesh type as an example, but is not particularly limited, and may be a star type or a tree type. Further, for example, the storage unit 50 may store route information that is information for transfer, and the control unit 30 may transfer the control information to other lighting fixtures according to the route information.

  The control unit 30 is a control device that receives control information related to the lighting state of the lighting fixture via the wireless communication unit 20 (receiving unit) and controls the lighting state of the lighting fixture 10a according to the received control information. Specifically, the control unit 30 controls the lighting state of the lighting fixture 10 a by controlling the light source unit 40. The control unit 30 is a processor that executes a control program stored in the storage unit 50, but may be realized by a microcomputer, a dedicated circuit, or the like.

  Here, the lighting state of the lighting fixture 10a is lighting that the lighting fixture 10a emits illumination light, turning off that is not emitting illumination light, blinking repeatedly turning on and off, changing the intensity of the illumination light, or It includes toning that is to be adjusted, toning that is to change or adjust the hue of illumination light, and the like. The control information includes an instruction related to the lighting state of the lighting fixture, which is operated by the user with the terminal device 60.

  The control unit 30 includes a transmission source determination unit 31, a hopping frequency acquisition unit 32, and a transmission frequency determination unit 33.

  The transmission source determination unit 31 is a processing unit that identifies the transmission source of the control information received via the wireless communication unit 20. The transmission source determination unit 31 identifies the transmission source from the transmission source address (source address) included in the communication packet that is the received control information. For example, the transmission source is specified from the device ID for each device stored in the storage unit 50 and the transmission source address included in the received communication packet. The transmission source address is, for example, an identification number (for example, a device ID) unique to the transmission source terminal device or lighting fixture. In addition, the communication packet includes information on a transmission source address, a transmission destination address, the number of hoppings, and a lighting state.

  The hopping frequency acquisition unit 32 acquires the hopping frequency (an example of the second hopping frequency) obtained by subtracting 1 from the hopping frequency (an example of the first hopping frequency) included in the received control information. When the second hopping frequency acquired by the hopping frequency acquisition unit 32 is 1 or more, the control unit 30 transmits control information to another lighting device via the wireless communication unit 20. That is, the lighting fixture 10a transfers control information to another lighting fixture. When the second hopping count is 0, the control unit 30 does not transmit control information to other lighting fixtures. That is, the lighting fixture 10a does not transfer control information to other lighting fixtures. This is to prevent one control information from being continuously transferred between a plurality of lighting fixtures. Note that the number of hoppings is, for example, information represented by one octet in a communication packet.

  Here, the number of hoppings indicates the number of times that control information can be transmitted from a device to a device (for example, the terminal device 60 to the lighting fixture 10a or the lighting fixture 10a to the lighting fixture 10b). The number of hoppings is set by the terminal device 60 that is the transmission source of the control information. For example, the user sets the hopping count.

  In the following description, as an example, a case where the number of hoppings included in the control information transmitted from the terminal device 60 is three will be described. In this case, the terminal device 60 or the lighting fixtures 10a and 10b can transmit control information up to a total of three times. The terminal device 60 transmits control information to the lighting fixture 10a by setting the number of hopping times to three. The lighting fixture 10a receives the control information from the terminal device 60, and subtracts 1 from the received number of hoppings. Since the hopping frequency acquisition unit 32 receives 3 hopping times (an example of the first hopping frequency), the hopping frequency obtained by subtracting 1 (an example of the second hopping frequency) is set to 2 times. This is to count that the control information is transmitted from the terminal device 60 to the lighting apparatus 10a as one transmission. Note that TTL (Time to live) = 3 in FIG. 1 indicates that the number of hoppings included in the control information is 3, and TTL = 2 in FIG. 1 is included in the control information. It shows that the number of hopping is two.

  Since the second hopping count is two, that is, transmission is still possible, the lighting fixture 10a transmits control information including the second hopping count to the lighting fixture 10b. The luminaire 10b subtracts 1 from the number of hoppings (specifically, 2 times) included in the received control information. This is to count that the control information is transmitted from the lighting fixture 10a to the lighting fixture 10b as being transmitted once. In this case, the subtracted hopping count is one. The lighting fixture 10b transmits control information including that the number of hops is one to another lighting fixture (not shown). Another luminaire subtracts 1 from the number of hops included in the received control information. This is to count that the control information is transmitted from the lighting fixture 10b to another lighting fixture as having been transmitted once. In this case, the subtracted hopping count is 0. That is, since another luminaire has zero hopping times, control information is not transmitted to the other luminaires.

  As described above, the hopping frequency acquisition unit 32 subtracts 1 from the hopping frequency included in the control information received via the wireless communication unit 20, and the control unit 30 determines that if the subtracted hopping frequency is 1 or more, Control which transmits control information to another lighting fixture via the wireless communication part 20 is performed.

  The transmission number determination unit 33 is a processing unit that determines the number of times that the lighting fixture 10a repeatedly transmits control information to other lighting fixtures. As described above, if the second hopping count is 1 or more, the lighting fixture transmits control information to another lighting fixture. For example, the lighting fixture 10a transmits control information to the lighting fixture 10b. In this case, the lighting fixture 10a repeatedly transmits control information to the lighting fixture 10b a plurality of times. This is to improve the reception probability, which is the probability that the lighting fixture 10b receives control information from the lighting fixture 10a.

  Although details will be described later, the transmission number determination unit 33 determines the number of transmissions that is the number of times the control information is repeatedly transmitted according to the hopping number included in the received control information. In the present embodiment, the number of transmissions is determined so that the smaller the number of hopping times, the smaller the number of repeated transmissions. For example, as described above, the number of hops included in the control information received by the lighting fixture 10a from the terminal device 60 is different from the number of hops included in the control information received by the lighting fixture 10b from the lighting fixture 10a. Specifically, the latter hop count is 1 less than the former hop count. In this case, the number of transmissions in which the luminaire 10a transmits control information to the luminaire 10b and the number of transmissions in which the luminaire 10b transmits control information to another luminaire are such that the former number of transmissions is greater. The transmission frequency determination unit 33 determines the transmission frequency. For example, the transmission count determination unit 33 sets the number of transmissions to (n−), where n is the number of hops transmitted from the terminal device 60 (hereinafter also referred to as the maximum hopping number) and m is the number of times the control information is hopped. m) It may be times. Further, the number of transmissions may be determined from a table in which the number of hoppings and the number of transmissions stored in the storage unit 50 are associated. Note that the control information may include information indicating the maximum number of hopping operations. For example, the transmission count determination unit 33 may acquire the hopped count m from the maximum hop count and the first hop count.

  FIG. 2 is a diagram illustrating an example of the table 70 in which the hopping count and the transmission count are associated with each other. Specifically, it is a table 70 in which the first hopping count, which is the hopping count included in the received control information, and the transmission count are associated with each other. As shown in FIG. 2, the table 70 is created such that the smaller the first number of hops, the smaller the number of transmissions. Although FIG. 2 shows an example in which the number of transmissions decreases by one every time the first hopping number decreases by one, the present invention is not limited to this. For example, every time the first hopping count decreases by one, the number of transmissions may decrease by two, or any other number.

  The light source unit 40 is a light source that emits illumination light. The light source unit 40 is realized by an LED (Light Emitting Diode) or the like, but may be realized by an incandescent bulb or a fluorescent lamp. Alternatively, it may be realized by a semiconductor laser, an organic EL (Electro Luminescence), an inorganic EL, or the like.

  The storage unit 50 is a storage device that stores a control program executed by the control unit 30, a table 70, and the like. For example, the storage unit 50 is realized by a flash memory or a semiconductor memory.

[1-2. Terminal device]
The terminal device 60 is a control device that controls a plurality of lighting fixtures. In the present embodiment, the terminal device 60 controls the lighting fixtures 10a and 10b. In the present embodiment, the terminal device 60 communicates directly with the lighting fixture 10a by wireless communication.

  The terminal device 60 is realized by, for example, a smartphone, that is, a high-function mobile phone terminal, a mobile phone terminal, a tablet terminal, a controller terminal (hereinafter referred to as a remote controller) developed exclusively, or a PC (Personal Computer). In the present embodiment, terminal device 60 is a smartphone. When the terminal device 60 is a smartphone, it is possible to operate the lighting device from the smartphone by downloading a dedicated application and performing an initial setting related to the operation with the lighting device.

  The terminal device 60 transmits control information to one lighting fixture among a plurality of lighting fixtures. The terminal device 60 selects one lighting fixture that automatically communicates on the application. For example, the terminal device 60 selects a luminaire to communicate based on the intensity of a signal received from each luminaire (RSS1: Received Signal Strength Indicator). For example, you may select as a lighting fixture which communicates the lighting fixture with the highest signal intensity which the terminal device 60 received. Hereinafter, the selected lighting fixture (the lighting fixture that directly communicates with the terminal device 60) is also referred to as a Bridge fixture. FIG. 1 shows an example in which the lighting device 10a is a Bridge device.

  In addition, although the illumination system 1 demonstrated the example provided with the one terminal device 60, the number of the terminal devices 60 with which the illumination system 1 is provided is not specifically limited. In addition, since the terminal device 60 and the lighting fixture perform wireless communication on a one-to-one basis, other terminal devices cannot communicate with the lighting fixture (for example, the lighting fixture 10a) communicating with the terminal device 60. For example, when the terminal device 60 enters the sleep mode, the communication between the terminal device 60 and the luminaire that has communicated with the terminal device 60 is disconnected. As a result, the other terminal device can communicate with the luminaire that has been communicating with the terminal device 60.

[2. Operation of lighting equipment]
Next, the operation of the lighting fixtures 10a and 10b will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the lighting fixtures 10a and 10b according to the present embodiment.

  First, operation | movement of the lighting fixture 10a which is a Bridge fixture, ie, the lighting fixture 10a which receives control information directly from the terminal device 60 is demonstrated.

  The lighting fixture 10 a receives control information from the terminal device 60 via the wireless communication unit 20. Specifically, the lighting fixture 10a receives the information regarding the lighting state of the some lighting fixture with which the lighting system 1 is provided, and the number of times of hopping from the terminal device 60 (Yes in S10). Note that the hop count included in the control information received by the lighting apparatus 10a from the terminal device 60 is an example of the first hop count. As described above, the first hopping frequency is 3 times as an example. Further, the control information including information regarding the lighting state and the first hopping count received from the terminal device 60 is an example of first information. That is, the lighting fixture 10a receives the 1st information containing the information regarding the lighting state of a lighting fixture, and the 1st hopping frequency via the wireless communication part 20 (reception part). The control unit 30 may store the received first information in the storage unit 50.

  In addition, when the lighting fixture 10a has not received the control information (No in S10), the lighting fixture 10a stands by until the control information is received.

  When receiving the control information via the wireless communication unit 20, the transmission source determination unit 31 determines the transmission source of the control information. Specifically, the transmission source is determined from the transmission source address included in the control information and the device ID for each device stored in the storage unit 50. In the present embodiment, the transmission source determination unit 31 determines that the terminal device 60 is the transmission source.

  Next, the hopping frequency acquisition unit 32 acquires the first hopping frequency from the received control information. As described above, since the first hop count is 3, the hop count acquisition unit 32 acquires 3 as the first hop count. Then, the hopping frequency acquisition unit 32 acquires a second hopping frequency obtained by subtracting 1 from the first hopping frequency (S20), and the control unit 30 determines whether or not the acquired second hopping frequency is 1 or more. Is determined (S30). When the second hopping count is 1 or more (Yes in S30), the control unit 30 determines to transmit the control information to another lighting fixture.

  In addition, when the second hopping count is not 1 or more, that is, when the second hopping count is 0 (No in S30), the control unit 30 determines not to transmit the control information to another lighting fixture. When the control part 30 makes the said determination, the control part 30 complete | finishes the process in transmission of control information.

  In the case of Yes in step S30, the control unit 30 transmits the first information received from the terminal device 60 and the second hopping number acquired by the hopping number acquisition unit 32 to other lighting fixtures. 2nd information which is information of this is generated (S40). For example, the control unit 30 generates the second information by updating the hopping count included in the received first information to the second hopping count. The transmission source address and the transmission destination address are also updated.

  Here, the 1st information which the lighting fixture 10a receives from the terminal device 60 and the 2nd information which the lighting fixture 10a transmits to another lighting fixture are demonstrated using FIG. FIG. 4 is a schematic diagram for explaining a data configuration of a communication packet according to the present embodiment. Specifically, FIG. 4A shows an example of the communication packet 80a in the first information, and FIG. 4B shows an example of the communication packet 80b in the second information.

  As shown in FIG. 4A and FIG. 4B, the communication packet includes a transmission source address, a transmission destination address, the number of hopping times, and information on the lighting state of the lighting fixture (FIG. 4A and FIG. (Lighting information in (b)).

  The hopping count included in the communication packet 80a shown in FIG. 4A is the first hopping count, the transmission source address is the device ID of the terminal device 60, and the transmission destination address is the device ID of the lighting fixture 10a. . Further, the information on the lighting state (hereinafter referred to as lighting information) is information indicating an instruction for the lighting fixture input to the terminal device 60 by the user. For example, FIG. 4A shows an example in which the lighting information is information including a light control level and a color control level of the lighting fixture.

  FIG. 4B illustrates an example of a communication packet 80b in the second information transmitted from the lighting fixture 10a to another lighting fixture (for example, the lighting fixture 10b). The hopping count included in the communication packet 80b is the second hopping count, the transmission source address is the device ID of the lighting fixture 10a, and the transmission destination address is the device ID of the lighting fixture 10b. The lighting information included in the second information is the same information as the lighting information included in the first information. That is, the lighting information included in the second information is information transmitted from the terminal device 60. Thereby, the lighting information which the terminal device 60 transmitted is transmitted to the lighting fixture 10b via the lighting fixture 10a. In other words, the lighting fixture 10a transfers control information to the lighting fixture 10b (an example of another lighting fixture).

  If the 2nd information for transmitting to other lighting fixtures is generated at Step S40, transmission number deciding part 33 will decide the number of transmissions which transmit the 2nd information (S50). Note that the number of transmissions is the number of times the lighting fixture 10a repeatedly transmits the second information to other lighting fixtures.

  The transmission source determination unit 31 determines that the lighting fixture 10a has received control information from the terminal device 60. When receiving the control information from the terminal device 60, the transmission count determination unit 33 determines, for example, that the number of transmissions is three or more times as the number of transmissions. The lighting fixture 10a that has received the control information from the terminal device 60 sets the number of transmissions to three times or more, thereby including a plurality of lighting fixtures included in the lighting system 1 including other lighting fixtures that are transmission destinations (transfer destinations). Control information can be received reliably. For example, the storage unit 50 stores the number of transmissions when the transmission source is the terminal device 60, and the transmission number determination unit 33 transmits the transmission number read from the storage unit 50 to other lighting fixtures. The number of times may be determined. Further, for example, the transmission number determination unit 33 may determine the number of transmissions from the table 70, or may determine the number of transmissions by a predetermined calculation formula. Also, the greater the number of first hops received from the terminal device 60, the more the number of transmissions may be determined. For example, the transmission count determination unit 33 determines the transmission count from the table 70 as 3 times.

  When the number of transmissions is determined, the control unit 30 repeatedly transmits the second information to another lighting fixture (for example, the lighting fixture 10b) via the wireless communication unit 20 (S60). For example, the control unit 30 transmits the second information by repeating the transmission three times. In other words, the wireless communication unit 20 (transmission unit) repeats the transmission of the second information and the number of transmissions acquired by the transmission number determination unit 33. In addition, the other lighting fixture (for example, lighting fixture 10b) which is a transmission destination which the lighting fixture 10a transmits 2nd information is an example of a 2nd lighting fixture. There may be one second lighting fixture or a plurality of second lighting fixtures.

  In addition, when transmitting the second information, the wireless communication unit 20 may transmit the second information using a plurality of wireless channels. For example, the wireless communication unit 20 may transmit the second information using three channels. For example, the reception state of the luminaire changes depending on the radio wave environment such as radio waves emitted from an electronic device (for example, an electronic device having a microwave oven or a wireless communication function) that is not included in the lighting system 1, so The transmission probability of the second information can be improved by transmitting the second information. For example, the receiving-side lighting fixture (for example, the lighting fixture 10b) receives the second information while changing the reception channel every predetermined time interval. For example, the predetermined time interval is 5 ms.

  When the second information is transmitted using a plurality of channels, the transmission of the second information for each of the plurality of channels is counted as one transmission. Since the number of transmissions is 3, the transmission of the second information for each of a plurality of channels is repeated 3 times. That is, the lighting fixture 10a transmits the second information nine times in total.

  And the control part 30 will control operation | movement of the light source part 40 based on the control information (lighting information) contained in 1st information, if 2nd information is transmitted via the wireless communication part 20. FIG. For example, when the control unit 30 receives control information for turning on the lighting fixture 10a, the control unit 30 turns on the light source unit 40. Moreover, when the control part 30 receives the control information which blinks the lighting fixture 10a, the control part 30 blinks the light source part 40. FIG. Specifically, the control unit 30 changes the lighting state of the light source unit 40 by controlling a drive circuit (not shown) that supplies power to the light source unit 40.

  As mentioned above, the lighting fixture 10a produces | generates 2nd information from the 1st information received from the terminal device 60 by radio | wireless communication, and transmits the said 2nd information to a 2nd lighting fixture. In other words, the lighting fixture 10a that is a Bridge fixture has a role of transferring information received from the terminal device 60 to the second lighting fixture. The lighting fixture 10a transmits the second information to the second lighting fixture three times or more, thereby improving the reception probability that the second lighting fixture receives the second information from the lighting fixture 10a. By receiving the second information by the second lighting fixture, the second lighting fixture can further transmit the second information to another lighting fixture. Therefore, a plurality of lighting fixtures included in the lighting system 1 are provided. The reception probability that the control information can be received can be improved.

  Next, the operation of the lighting fixture 10b that receives control information from the lighting fixture 10a that is a Bridge fixture will be described. In addition, about the same operation | movement as the lighting fixture 10a, description may be abbreviate | omitted.

  The lighting fixture 10b receives control information from the lighting fixture 10a via the wireless communication unit 20. Specifically, the lighting fixture 10a receives information including lighting states of the plurality of lighting fixtures included in the lighting system 1 and the number of hoppings from the lighting fixture 10a (Yes in S10). In addition, the lighting fixture 10a which transmitted control information to the lighting fixture 10b is an example of a 1st lighting fixture. Further, the number of hops included in the control information received by the lighting fixture 10b from the lighting fixture 10a is an example of a first hopping count. Hereinafter, a case where the first hopping count is two will be described as an example. Moreover, the control information which the lighting fixture 10b received from the lighting fixture 10a is an example of 1st information. In addition, when the lighting fixture 10b is not receiving control information (it is No at S10), the lighting fixture 10b waits until receiving control information.

  When receiving the control information via the wireless communication unit 20, the transmission source determination unit 31 determines the transmission source of the control information. The determination of the transmission source performed by the lighting fixture 10b is the same as the transmission source determination performed by the lighting fixture 10a.

  Next, the hopping frequency acquisition unit 32 acquires the first hopping frequency from the received control information. The number of hops included in the control information received from the lighting fixture 10b is two. The process of step S20 and step S30 is the same as that of the lighting fixture 10a. The hopping frequency acquisition unit 32 acquires 1 as the second hopping frequency.

  If yes in step S30, the control unit 30 transmits to the other lighting fixtures from the first information received from the lighting fixture 10a and the second hopping count acquired by the hopping count acquisition portion 32. Second information as information is generated (S40).

  If the 2nd information for transmitting to other lighting fixtures is generated at Step S40, transmission number deciding part 33 will decide the number of transmissions which transmit the 2nd information (S50). Here, the case where it determines with the preset formula is demonstrated. The predetermined calculation formula is, for example, when the number of hops included in the control information transmitted by the terminal device 60 is n, and the number m of hops before the lighting apparatus 10b receives the control signal is (n -M). In the present embodiment, n is 3 times, and m is 2 times (one time transmitted from the terminal device 60 to the lighting fixture 10a and one time transmitted from the lighting fixture 10a to the lighting fixture 10b). . That is, nm = 1, and the number of times that the lighting fixture 10b transmits the second control information is one. In other words, the transmission count determination unit 33 determines the transmission count to be one by a preset calculation formula.

  For example, the number of transmissions may be determined using the table 70. Specifically, as illustrated in FIG. 2, the transmission count determination unit 33 may determine the transmission count from the first hopping count. The first hopping number is two. From the table 70, the number of transmissions corresponding to the first hopping number is two. That is, the transmission frequency determination unit 33 determines the transmission frequency of the second information to be 2 times. And the lighting fixture 10b repeats twice with respect to another lighting fixture, and transmits 2nd information.

  The lighting fixture 10a repeatedly transmits information three times as described above. The lighting fixture 10b transmits the second information once or twice as described above. That is, the lighting fixture 10b has fewer transmissions than the lighting fixture 10a. For example, when the table 70 is used, the number-of-transmissions determination unit 33 is three times (an example of the first number of transmissions) that is the number of times the lighting device 10a has transmitted and the number of times of transmission corresponding to the number of hoppings received by the lighting device 10a 2) (one example of the second transmission count) obtained by subtracting 1 from) is determined to be the transmission count corresponding to the hopping count received by the lighting fixture 10b. Hereinafter, an example in which the number of transmissions of the lighting apparatus 10b transmitting the second information is two will be described.

  When the number of transmissions is determined, the control unit 30 repeatedly transmits the second information to another lighting device (not shown) via the wireless communication unit 20 (transmission unit) (S60). For example, the control unit 30 transmits the second information by repeating twice the number of transmissions. In addition, the other lighting fixture which is the transmission destination which the lighting fixture 10b transmits 2nd information is an example of a 2nd lighting fixture. There may be one second lighting fixture or a plurality of second lighting fixtures.

  And the control part 30 will control operation | movement of the light source part 40 based on the control information contained in 1st information, if 2nd information is transmitted via the wireless communication part 20. FIG. The control of the light source unit 40 is the same as that of the lighting fixture 10a, and the description thereof is omitted.

  As described above, the number of times the lighting fixture transmits the control information is determined according to the number of times the control information is hopped. Specifically, the transmission number determination unit 33 determines the smaller number of transmissions as the number of transmissions is smaller. Therefore, as the control information is hopped, the number of times (the number of transmissions) that the luminaire receiving the control information repeatedly transmits the control information to other luminaires decreases.

  As described above, the luminaire 10b generates the second information from the first information received from the luminaire 10a (an example of the first luminaire) by wireless communication, and uses the second information as another illumination. Transmit to the fixture (an example of a second lighting fixture). In other words, the lighting fixture 10b has a role of transferring lighting information received from the lighting fixture 10a to the second lighting fixture. The number of transmissions by which the lighting fixture 10b transmits the second information to other lighting fixtures is determined to be a smaller number of transmissions as the first hopping count is smaller. For example, the transmission frequency determination unit 33 determines the number of transmissions less than the transmission frequency transmitted by the lighting fixture 10a. Further, for example, the transmission count determination unit 33 sets 1 from the first transmission count (the transmission count corresponding to the hopping count received by the lighting fixture 10a, for example, three times) that is the transmission count transmitted by the lighting fixture 10a. The subtracted second transmission count (the transmission count corresponding to the hopping count received by the lighting apparatus 10b, for example, 2) is determined as the transmission count.

  This reduces the number of times the received lighting fixture transmits the second information each time it is hopped. That is, as a whole lighting system 1, the number of transmissions of information (in other words, the amount of information transmitted) is reduced. Therefore, interference between radio signals can be suppressed, and the reception probability of control information can be improved. For example, even if there are many lighting fixtures with which the illumination system 1 is provided, since the frequency | count of transmission which transmits control information can be suppressed, interference between radio signals can be reduced. That is, even if the number of lighting fixtures is large, the lighting system 1 according to the present embodiment can maintain a high reception probability.

[3. effect]
Next, effects of the lighting fixtures 10a and 10b according to the present embodiment will be described.

  The lighting fixtures 10a and 10b according to the present embodiment have a multi-hop function of transferring information received from the terminal device 60 or the first lighting fixture to the second lighting fixture (for example, the lighting fixture 10b) by wireless communication. First information including information on the lighting device (for example, the lighting device 10a), the light source (the light source unit 40), the lighting state of the lighting device (for example, the lighting device 10a), and the first hopping count. The reception unit (for example, the wireless communication unit 20) that receives from the terminal device 60 or the first lighting fixture, and obtains the second hopping count by subtracting 1 from the first hopping count included in the first information. If the second hopping count is 1 or more, the second luminaire displays the second information including information on the lighting state and the second hopping count. Transmitting portion for transmitting (e.g., the wireless communication unit 20) provided with, a transmission number determining unit 33 that determines the number of transmission times repeatedly transmits the second information to the second lighting fixture. Then, the transmission number determination unit 33 determines the smaller number of transmissions as the first hopping number is smaller, and the transmission unit repeats the transmission of the second information and the transmission number determined by the transmission number determination unit 33.

  Thereby, the number of transmissions for transmitting the second information is determined according to the first hopping number. Further, the first hopping count becomes a smaller value as the control information is hopped (transmitted). Specifically, the first hopping count decreases by one from the hopping count transmitted by the terminal device 60 every time hopping is performed. Since the transmission number determination unit 33 determines the smaller number of transmissions as the first hopping number is smaller, each time the control information is hopped, the luminaire that has received the control information transmits the control information to another luminaire. The number of transmissions is reduced. Therefore, when the lighting system 1 including a plurality of lighting fixtures is used in a house or the like, the number of transmissions of control information wirelessly communicated between the lighting fixtures can be reduced, so that occurrence of radio signal interference can be suppressed. The reception probability of control information can be improved. In particular, there is a higher effect on the lighting system 1 including a large number of lighting fixtures. That is, the lighting fixture according to the present embodiment can appropriately perform wireless communication according to the use environment.

  When the lighting fixture (for example, the lighting fixture 10a) receives the first information from the terminal device 60, the transmission count determination unit 33 determines the number of transmissions as three or more times, and the lighting fixture (for example, the lighting fixture). When the fixture 10b) receives the first information from the first lighting fixture (for example, the lighting fixture 10a), the transmission number determination unit 33 is the number of times the first lighting fixture has transmitted and is the first hopping. The second transmission count obtained by subtracting 1 from the first transmission count that is the transmission count corresponding to the count may be determined as the transmission count corresponding to the second hopping count.

  Thereby, since the lighting fixture 10a (Bridge appliance) which received 1st information from the terminal device 60 transmits 2nd information repeatedly 3 times or more, the lighting fixture 10b (2nd lighting fixture) is 2nd information. Can be improved in reception probability. And the lighting fixture 10b which received the 2nd information transmitted from the lighting fixture 10a transmits 2nd information to another lighting fixture further. Therefore, it is possible to improve the reception probability that all of the plurality of lighting fixtures included in the lighting system 1 can receive the control information.

  In addition, the number of transmissions determination unit 33 determines the number of transmissions by which the lighting fixture 10b transmits the second information as the second number of transmissions obtained by subtracting 1 from the number of first transmissions, thereby the number of transmissions of the lighting fixture 10b. Is less than the number of transmissions of the lighting fixture 10a. That is, since the number of transmissions of control information of the lighting system 1 can be reduced, interference between radio signals can be reduced.

  As described above, the number of transmissions that the Bridge fixture transmits is determined to be three or more, and the second lighting fixture transmits fewer control times than the first lighting fixture, thereby transmitting the control information. It is possible to improve the reception probability while reducing.

(Embodiment 2)
Hereinafter, an illumination system including the terminal device according to the present embodiment will be described with reference to FIGS. 5A to 6. In the present embodiment, a case will be described in which only predetermined lighting fixtures are controlled for a demonstration or the like from among a plurality of lighting fixtures displayed at a store or the like.

  The lighting system 100 according to the present embodiment includes a plurality of lighting fixtures (lighting fixtures 10a, 10b, 10c) and a remote controller 110 (remote operation device). The plurality of lighting fixtures and the remote controller 110 have a wireless communication function, and the plurality of lighting fixtures change the lighting state based on control information transmitted from the remote control 110. 5A and 5B show an example in which there are three lighting fixtures, the number of lighting fixtures provided in the lighting system 100 is not particularly limited. Moreover, the some lighting fixture which concerns on this Embodiment is the structure same as the lighting fixture demonstrated in Embodiment 1, and abbreviate | omits description of a lighting fixture. Note that the lighting fixture used in the lighting system 100 is not limited to the lighting fixture according to the first embodiment. Any lighting device having a wireless communication function may be used.

  Illumination system 100 according to the present embodiment will be described with reference to FIGS. 5A and 5B. FIG. 5A is a block diagram showing an overall configuration of lighting system 100 including a control information transfer path when remote controller 110 is operating in the normal use mode. FIG. 5B is a block diagram showing an overall configuration of lighting system 100 including a control information transfer path when remote controller 110 is operating in the non-normal use mode.

  First, the remote controller 110 will be described. Note that the remote controller 110 and the plurality of lighting fixtures in FIGS. 5A and 5B have the same configuration, and will be described with reference to FIG. 5A.

  As shown in FIG. 5A, the remote controller 110 includes a mode acquisition unit 120, an input unit 130, a control unit 140, a storage unit 150, and a wireless communication unit 160.

  The mode acquisition unit 120 is an acquisition unit that receives, from a user, switching of modes for operating a plurality of lighting fixtures. In the present embodiment, remote controller 110 operates in a normal use mode in which a plurality of lighting fixtures included in lighting system 100 is operated, and in a non-operating mode for operating only a specific lighting fixture among the plurality of lighting fixtures included in lighting system 100. There are two modes of normal use mode. For example, the normal use mode is a mode used when a plurality of lighting fixtures installed in a house or office are operated substantially simultaneously, and the non-normal use mode is a plurality of lighting fixtures displayed at a storefront. In this mode, only a specific lighting fixture is operated, or only a specific lighting fixture is operated in order to inspect the lighting fixture in a factory or the like. Note that the remote controller 110 may have other modes.

  The mode acquisition unit 120 is, for example, a switch, and the user may acquire the switching between the two modes by switching the switch, or acquire the mode switching by performing a predetermined operation on the input unit 130. May be. For example, the predetermined operation means that, when the input unit 130 is a button, the predetermined button is pressed and held for a predetermined time or longer. Although not shown, the remote controller 110 may include a display unit that displays a mode that is currently set.

  The input unit 130 is a user interface that receives an instruction of a lighting state of a lighting fixture from a user, and is, for example, a push button.

  The control unit 140 controls each unit in accordance with a user operation. For example, when a lighting state is input from the user via the input unit 130 (change in lighting state is input), the control unit 140 transmits control information to the lighting apparatus via the wireless communication unit 160 (an example of an output unit). To do. In FIG. 5A and FIG. 5B, the remote control 110 has shown the example which is transmitting control information with respect to the lighting fixture 10a.

  The control unit 140 is a processor that executes a control program stored in the storage unit 150, but may be realized by a microcomputer or a dedicated circuit.

  The hopping frequency determination unit 141 included in the control unit 140 determines the hopping frequency included in the transmitted control information. Specifically, the hopping frequency determination unit 141 determines the hopping frequency according to the currently set mode. For example, if the normal hopping mode is set, the hopping frequency determination unit 141 determines the hopping frequency determined in advance as the control information to be transmitted as control information, and is set to the non-normal usage mode. The number of hops transmitted as control information is determined as one. Remote controller 110 according to the present embodiment is characterized in that the number of hops can be changed in accordance with the mode, and the number of hops when the non-normal use mode is set is determined as one. Note that the number of hoppings set in advance is stored in the storage unit 150, for example, and the hopping number determination unit 141 controls the number of hoppings read from the storage unit 150 in the normal setting mode. The number of hoppings to be transmitted may be determined.

  The storage unit 150 is a storage device that stores a control program executed by the control unit 140, the number of times of hopping, and the like. For example, the storage unit 150 is realized by a flash memory or a semiconductor memory.

  The wireless communication unit 160 is a wireless communication interface that performs wireless communication. The wireless communication unit 160 establishes a wireless communication connection with a communication partner apparatus for wireless communication, and then performs wireless communication with the communication partner apparatus. In the present embodiment, wireless communication unit 160 establishes a wireless communication connection with a lighting fixture (in this embodiment, lighting fixture 10a). The wireless communication unit 160 is an example of an output unit that transmits control information. Note that the wireless communication is wireless communication using the Bluetooth (registered trademark) communication standard as an example. In this case, the wireless communication unit 160 is a communication module (communication circuit) compatible with the Bluetooth (registered trademark) communication standard. Note that the communication standard is not limited to Bluetooth (registered trademark), and may be wireless communication using a communication standard such as a wireless LAN (for example, Wi-Fi (registered trademark)).

  In addition, lighting fixture 10a, 10b, 10c which concerns on this Embodiment performs multihop communication. Specifically, when the luminaire 10a receives control information from the remote controller 110 via the wireless communication unit, the luminaire 10a receives the control information from the remote controller 110 via the wireless communication unit. To send. Further, for example, the storage unit 150 may store route information that is information for transmission, and the control unit 140 may transmit control information to the lighting apparatus according to the route information. That is, the lighting fixtures 10a, 10b, and 10c according to the present embodiment are lighting fixtures having a multi-hop function. In addition, remote controller 110 according to the present embodiment is a remote operation device for controlling operations of a plurality of lighting fixtures having a multi-hop function.

  Next, the operation of the remote controller 110 will be described with reference to FIG. FIG. 6 is a flowchart showing an operation of remote control 110 according to the present embodiment.

  When remote controller 110 receives a change in lighting state from the user via input unit 130 (Yes in S110), hop count determination unit 141 confirms the currently set mode. When the currently set mode is the normal use mode (Yes in S120), the hopping frequency determination unit 141 determines the hopping frequency to be transmitted as control information as a predetermined hopping frequency (S130). When the currently set mode is the non-normal use mode (No in S120), the hopping frequency determination unit 141 determines the hopping frequency to be transmitted as control information once (S140). In addition, when the change of the lighting state from the user is not received via the input unit 130 (No in S110), the remote controller 110 is on standby until the change of the lighting state is received.

  When the hopping frequency is determined by the hopping frequency determination unit 141, the control unit 140 generates control information to be transmitted from the hopping frequency and the lighting state received by the input unit 130 (S150), and the control information is It transmits to the lighting fixture 10a via the wireless communication part 160 (output part). The control information includes a transmission source address (for example, a device ID of the remote controller 110) and a transmission destination address (for example, a device ID of the lighting fixture 10a).

  For example, conventionally, the mode is switched by changing the output when the remote control transmits control information. Specifically, when operating only a specific lighting fixture, the control information reaches only the specific lighting fixture by reducing the output when transmitting the control information. However, in the case of a lighting fixture that performs multi-hop communication like the lighting fixture according to the present embodiment, when at least one of the lighting fixtures receives control information from the remote controller, the other lighting fixtures are also controlled by the multi-hop communication. Receive information. That is, in the conventional method, it is difficult to operate only a specific lighting fixture from among a plurality of lighting fixtures that perform multi-hop communication.

  On the other hand, remote control 110 according to the present embodiment changes the control information to be transmitted according to the mode. Specifically, the number of hoppings included in the control information is changed according to the mode. For example, in the non-normal use mode, only a specific lighting fixture needs to operate. Therefore, by setting the number of hoppings included in the control information to one, the lighting fixture that has received the control information can receive other lighting fixtures. Do not transfer the control information to the appliance. Thereby, only a specific lighting fixture can be operated from among a plurality of lighting fixtures performing multi-hop communication.

  Next, a transfer path of control information in the normal use mode and the non-normal use mode will be described with reference to FIGS. 5A and 5B.

  FIG. 5A shows a control information transfer path in the normal use mode. For example, when the predetermined number of hops is 3, the remote controller 110 transmits control information (TTL = 3 shown in FIG. 5A) indicating that the number of hops is 3 to the lighting apparatus 10a. The lighting apparatus 10a has two hopping times (an example of the second hopping number) obtained by subtracting 1 from the hopping number (an example of the first hopping number) included in the received control information, that is, the second hopping. Since the number of times is one or more, the control information is transmitted to other lighting fixtures (for example, lighting fixtures 10b and 10c). That is, the lighting fixture 10a transfers control information to another lighting fixture. And the lighting fixtures 10b and 10c which received control information from the lighting fixture 10a transmit control information to another lighting fixture (not shown), respectively. Thereby, the control information from the remote controller 110 can be received by a plurality of lighting fixtures.

  Note that the lighting fixtures 10b and 10c to which the lighting fixture 10a transmits control information are examples of the second lighting fixture. Further, when viewed from the lighting fixtures 10b and 10c, the lighting fixture 10a that transmits the control information to the lighting fixtures 10b and 10c is an example of the first lighting fixture, and another lighting that the lighting fixtures 10b and 10c transmit the control information. The fixture is an example of a second lighting fixture.

  FIG. 5B shows a transfer path of control information in the non-normal use mode. The remote controller 110 transmits control information (TTL = 1 shown in FIG. 5B) that indicates the number of hopping times to the lighting apparatus 10a. The lighting fixture 10a has zero hopping count (an example of the second hopping count) obtained by subtracting 1 from the hopping count (an example of the first hopping count) included in the received control information. Does not transfer control information. Thereby, the control information from the remote controller 110 can be received only by a specific lighting fixture (for example, the lighting fixture 10a), and only the lighting fixture that has received the control information can be operated. Further, only a specific lighting fixture can be operated by a simple operation such as changing the mode by the mode acquisition unit 120 of the remote controller 110 without changing the setting on the lighting fixture side.

  Note that the remote controller 110 may transmit the control information to the luminaire by reducing the output in the non-normal mode. Thereby, only a specific lighting fixture can be operated more reliably. Moreover, although the example which the remote control 110 transmits a control signal was demonstrated above, it is not limited to this. For example, it may be realized by a smart phone, that is, a high-function mobile phone terminal, a mobile phone terminal, a tablet terminal, or a PC (Personal Computer). That is, the remote controller 110 is an example of a terminal device.

  The terminal device according to the present embodiment is a terminal device for operating a lighting fixture having a multi-hop function for transferring information received by wireless communication to other lighting fixtures (for example, lighting fixtures 10b and 10c). The terminal device includes a mode acquisition unit 120 that accepts switching between the normal use mode and the non-normal use mode, an input unit 130 that accepts the lighting state of the luminaire from the user, a hop count determination unit 141 that determines the hop count, An output unit (for example, a wireless communication unit 160) that transmits control information including information on the lighting state and the number of times of hopping to the lighting device (for example, the lighting device 10a). Then, when the normal use mode is set, the hop count determination unit 141 determines that the predetermined hop count is the hop count transmitted as control information, and is set to the non-normal use mode. If it is determined that the number of hops transmitted as the control information is one.

  Thereby, it is possible to change whether or not only a specific lighting fixture (for example, the lighting fixture 10a) is operated by a simple operation in which the user switches the mode with the terminal device (for example, the remote controller 110). Specifically, when the non-normal use mode is set, the hopping frequency determination unit 141 determines the hopping frequency to be 1, and transmits control information including the determined hopping frequency to the lighting apparatus 10a. Only the lighting fixture 10a that has received the control information can be operated. That is, the terminal device can cause the control information to be received only by the luminaire to be operated (the luminaire intended by the user) according to the use environment such as the normal use mode or the non-normal use mode. Therefore, the terminal apparatus according to the present embodiment can appropriately perform wireless communication according to the usage environment.
