By switching the signal line for communication, the lighting fixture to be operated can be switched.

Further, when a LAN is used for transmission of control signals, if control signals from a plurality of operation devices are transmitted to the LAN connected to a studio or the like, communication traffic on the LAN increases. As a result, the communication load increases, and there is concern about communication delays. Therefore, a virtual LAN (VLAN) is configured for each space such as a studio, and a LAN cable or the like dedicated to the lighting equipment to be operated is installed between the studio or the like in which the lighting equipment to be operated is installed and the controller. By switching the LAN cable or the like for communication, the lighting fixture to be operated can be switched.

However, when switching wiring such as a signal line or a LAN cable used for communication in this way, an operation for switching the wiring is required. Furthermore, every time the number of studios or the like in which operation devices or lighting fixtures to be operated increases, wiring needs to be increased, and large-scale renovation of facilities is required.

(Embodiment 1)
A lighting system according to the present embodiment will be described below.

[Configuration of lighting system]
First, a schematic configuration of a lighting system according to this embodiment will be described. FIG. 1 is a diagram schematically showing the configuration of a lighting system 100 according to this embodiment.

As shown in FIG. 1, lighting system 100 according to the present embodiment includes lighting fixtures installed in each of a plurality of spaces, a plurality of operators, and a plurality of control devices. In FIG. 1, an example is shown in which a lighting system 100 includes lighting fixtures installed in N spaces, M operators, and N controllers. Although FIG. 1 shows an example in which M and N are 3 or more, the present invention is not limited to this. M may be an integer of 1 or more. Also, N may be an integer of 2 or more. That is, M is an integer of 1 or more, and N is an integer of 2 or more.

The lighting system 100 is, for example, a lighting system installed in a facility where lighting effects are performed in a plurality of spaces, such as a television station, a concert hall facility, or a theater.

The lighting system 100 includes a plurality of first lighting fixtures 10a installed in the first space 1a, a plurality of second lighting fixtures 10b installed in the second space 1b, ... installed in the Nth space 1n. and an Nth lighting fixture 10n. The lighting system 100 also includes a first operating device 30a that transmits a first control signal, a second operating device 30b that transmits a second control signal, and an Mth operating device 30m that transmits an Mth control signal. and The lighting system 100 also includes a first control device 50a, a second control device 50b, and an Nth control device 50n. The first space 1a, the second space 1b, and the Nth space 1n are different spaces. The first space 1a, the second space 1b, and the Nth space 1n are, for example, studios, halls, or stages.

In this specification, the first lighting fixture 10a, the second lighting fixture 10b, . Also, the first operating device 30a, the second operating device 30b, . Also, the first control device 50a, the second control device 50b, . Also, the first control signal, the second control signal, .

Although not shown in FIG. 1, power is supplied from a power supply to each of the lighting equipment, the operating device, and the control device.

A first lighting fixture 10a is connected to a first individual network 2a. A second lighting fixture 10b is connected to a second individual network 2b. Similarly thereafter, the Nth lighting fixture 10n is connected to the Nth individual network 2n. In this specification, the first individual network 2a is an example of a first network, and the second individual network 2b is an example of a second network.

The first lighting fixture 10a is, for example, a horizon light, a downlight, a spotlight, a floodlight, or the like used in a studio, hall, stage, or the like. The first lighting fixture 10a has, for example, semiconductor light-emitting elements such as LEDs (Light Emitting Diodes), organic ELs (Electro Luminescence), fluorescent lamps, and incandescent lamps as light sources. The first lighting fixture 10a may have a motor or the like for changing the irradiation direction of light. The first lighting fixture 10a is arranged, for example, at an arbitrary location such as the floor or ceiling of a space such as a studio where it is installed. Alternatively, the first lighting fixture 10a may be suspended from a suspension fixture such as a baton installed on the ceiling.

The number of the first lighting fixtures 10a installed in the first space 1a is plural in the example shown in FIG. 1, but may be one.

The first lighting fixture 10a receives a control signal from the operator and dims the emitted light according to the received control signal. The first lighting fixture 10a may adjust the color of emitted light, change the illumination range, and the like, according to the received control signal. Thereby, the 1st lighting fixture 10a performs lighting effects of a studio, a hall, a stage, etc., for example. The first lighting fixture 10a is, for example, an sACN signal compatible lighting fixture that dims according to a control signal (sACN signal) of the sACN (streaming Architecture for Control Networks) protocol for communicating DMX signals via Ethernet. That is, the first lighting fixture 10a dims according to the sACN signal from the operator received via the first individual network 2a. The sACN protocol is a communication protocol capable of transmitting a plurality of systems of control signals by a multicast system, with data packets of DMX signals of 512 channels as one system (universe) of control signals.

The control signal has identification information for identifying the lighting fixture to be dimmed. When an sACN signal is used as a control signal, a universe number, which is an ID (Identification) number, is assigned to each system of the sACN signal, and the universe number can be used as identification information. That is, the first lighting fixture 10a dims the emitted light according to the sACN signal having the universe number assigned to the first lighting fixture 10a. In this specification, the universe number may be referred to as "ID".

Also, for example, each first lighting fixture 10a is assigned a DMX address. Each first lighting fixture 10a counts the number of DMX signal channels in the received control signal, takes in the DMX signal whose counted number matches the assigned DMX address, and adjusts the emitted light.

The communication method between the controller and the lighting fixture is not limited to the sACN protocol that transmits DMX signals by multicast, but may be another communication protocol that can transmit control signals to Ethernet. A communication method between the controller and the lighting fixture may be, for example, an Art-net protocol that transmits DMX signals in a broadcast manner.

In addition, for communication between the controller and the lighting equipment, specified low-power radio, ZigBee (registered trademark) or Bluetooth (registered trademark), or Wi-Fi (registered (trademark) may be used.

Other lighting fixtures such as the second lighting fixture 10b are similar to the first lighting fixture 10a, and thus detailed description thereof will be omitted.

Each of the first lighting fixture 10a, the second lighting fixture 10b, and the Nth lighting fixture 10n dims according to the received control signal when the received control signal has common identification information common to the lighting fixtures. good too. For example, the same universe number is assigned to the first lighting fixture 10a, the second lighting fixture 10b and the Nth lighting fixture 10n. In FIG. 1, for example, the universe numbers of the first lighting fixture 10a, the second lighting fixture 10b, and the Nth lighting fixture 10n are 1, 2, 3, and 4, respectively. In this case, although the details will be described later, the control device converts the identification information of the control signal into common identification information. As a result, it is possible to unify the settings of lighting fixtures installed in different spaces, thereby facilitating setting, maintenance, and the like.

The first operator 30a is connected to the common network 3 and transmits to the common network 3 a first control signal for dimming the first lighting fixture 10a, the second lighting fixture 10b or the Nth lighting fixture 10n. The second controller 30b is connected to the common network 3 and transmits to the common network 3 a second control signal for dimming the first lighting fixture 10a, the second lighting fixture 10b or the Nth lighting fixture 10n. Thereafter, similarly, the M-th operator 30m is connected to the common network 3, and transmits the M-th control signal to the common network 3 for dimming the first lighting fixture 10a, the second lighting fixture 10b, or the N-th lighting fixture 10n. Send. For example, the sACN signal is used as the control signal as described above.

The operation device is, for example, a dimming console having a fader or the like for setting the dimming level. The operation device may be a tablet terminal, a smartphone, a personal computer, or the like in which an application for dimming is installed.

The first control device 50a is connected to the first individual network 2a and the common network 3 between the first individual network 2a, the second individual network 2b, and the N-th individual network 2n. A control signal such as a control signal is received. The second control device 50 b is connected to the second individual network 2 b and the common network 3 and receives control signals from the common network 3 . Similarly thereafter, the Nth control device 50n is connected to the Nth individual network 2n and the common network 3, and receives control signals from the common network 3. FIG. In this specification, the common network 3 is an example of a third network.

A common network 3 is commonly used for communication between each operating device and each lighting fixture. A first control device 50a is interposed between the common network 3 and the first individual network 2a. A second control device 50b is interposed between the common network 3 and the second individual network 2b. An Nth controller 50n is interposed between the common network 3 and the Nth individual network 2n. The common network 3 is not directly connected to lighting fixtures.

For the networks such as the first individual network 2a, the second individual network 2b, the N-th individual network 2n, and the common network 3, for example, a LAN or the like is used. A LAN used for the network may be a wired LAN or a wireless LAN. When a wired LAN is used for the network, specifically, the wired LAN is configured by LAN cables, switching hubs, and the like. Also, if the communication distance is long, an optical fiber may be used instead of the LAN cable.

The selection unit 33 is composed of, for example, various buttons. The selection unit 33 may be configured by a touch panel or the like.

The control unit 34 causes the first communication unit 31 to transmit a first control signal based on the operation received by the operation unit 32 and the selection unit 33 . For example, when the operation unit 32 is composed of a plurality of faders, the control unit 34 outputs a first control signal having dimming information based on the accepted fader operation and the universe number associated with the operated fader. is transmitted to the first communication unit 31 .

[Operation of operation device and control device]
Next, operations of the operating device and the control device according to the present embodiment will be described. The operations of the first manipulator 30a and the first control device 50a will be described below. Other operating devices such as the second operating device 30b and other control devices such as the second control device 50b operate in the same manner as the first operating device 30a and the first control device 50a, respectively. are omitted.

FIG. 5 is a flowchart showing an example of the operation of transmitting the first control signal by the first manipulator 30a.

First, the selection unit 33 of the first operation device 30a receives an operation of selecting a lighting fixture to be dimmed by the first control signal (S11). For example, the user selects the first lighting fixture 10a or the second lighting fixture 10b as a dimming target.

Next, the operation unit 32 of the first operation device 30a receives an operation for dimming the lighting fixture to be dimmed (S12). For example, the user sets the dimming level by operating the operation unit 32 such as a fader.

Next, the first operation device 30a transmits to the common network 3 a first control signal based on the operations accepted by the selection unit 33 and the operation unit 32 in steps S11 and S12 (S13). For example, the control unit 34 refers to the dimming target information in the storage unit 35 shown in FIG. The first communication unit 31 is caused to transmit the first control signal having the dimming information based on.

When the second manipulator 30b transmits the second control signal, the second manipulator 30b also transmits the second control signal to the common network 3 in the same manner as the method shown in FIG.

FIG. 6 is a flow chart showing an example of the operation when the first control device 50a receives the first control signal via the common network 3. As shown in FIG.

First, the second communication unit 52 of the first control device 50a receives a first control signal from the common network 3 (S21). The received first control signal is, for example, the first control signal transmitted from the first manipulator 30a in step S13 described above. The communication control unit 53 causes the storage unit 54 to temporarily store the received first control signal. Next, the communication control unit 53 of the first control device 50a determines whether or not the dimming target of the received first control signal is the first lighting fixture 10a (S22). For example, the communication control unit 53 refers to the determination information shown in FIG. 4 to determine the dimming target of the first control signal.

When the first control device 50a determines that the dimming target of the received first control signal is the first lighting fixture (Yes in S22), the first control device 50a sets the identification information of the received first control signal to the common identification information. Convert (S23). The first control device 50a then transmits the first control signal to the first individual network 2a (S24). For example, the communication control unit 53 converts the universe number of the first control signal and causes the first communication unit 51 to transmit the first control signal to the first individual network 2a. The first lighting fixture 10a receives the first control signal and dims the emitted light according to the received first control signal.

When the first control device 50a determines that the dimming target of the received first control signal is a lighting fixture different from the first lighting fixture (No in S22), the first control signal is transmitted to the first individual network 2a. is not transmitted (S25). In other words, in step S25, the communication control unit 53 does not cause the first communication unit 51 to transmit the received first control signal to the first individual network 2a. A lighting fixture different from the first lighting fixture 10a is, for example, a second lighting fixture 10b. The communication control unit 53 erases the first control signal stored in the storage unit 54 and discards the first control signal. This reduces the traffic in the first individual network 2a.

Note that, even when the first control device 50a receives a control signal other than the first control signal from the common network 3, the method similar to the method shown in FIG. process. Also, when the second control device 50b receives a control signal from the common network, it determines the control signal and performs subsequent processing in the same manner as the method shown in FIG.

[Example of lighting system operation]
Next, an operation example of lighting system 100 according to the present embodiment will be described. In the operation example below, the sACN protocol is used as the communication method between the operation device and the lighting fixture. Further, the first operating device 30a and the second operating device 30b simultaneously transmit control signals (sACN signals) of a plurality of systems, specifically four systems. Moreover, although each operation example shows an operation related to the transmission of the control signal once, the control signal is repeatedly transmitted while the operation unit dims the lighting fixture. In this specification, simultaneous transmission of a plurality of systems of control signals is not limited to the case where the operation device transmits a plurality of systems of control signals at the same timing as shown in the operation example, This includes the case where the period in which the control signal is repeatedly transmitted for lighting is substantially the same. For example, while the lighting equipment is dimmed, the control signals of the multiple systems may be repeatedly transmitted at different timings for each system. Further, in each operation example below, the universe number is denoted as ID.

In each operation example, the first control device 50a is interposed between the first individual network 2a and the common network 3, and the first individual network 2a and the common network 3 are not directly connected. The first individual network 2a is connected to the first communication section 51 of the first control device 50a, and the common network 3 is connected to the second communication section 52 of the first control device 50a. The connection between the second individual network 2b, the common network 3 and the second control device 50b is the same as above.

(1) Operation example 1
First, operation example 1 of lighting system 100 according to the present embodiment will be described. FIG. 7 is a sequence diagram of Operation Example 1 of lighting system 100 according to the present embodiment. In operation example 1, the first lighting device 10a is dimmed by operating the first operating device 30a, and the second lighting device 10b is dimmed by operating the second operating device 30b. In Operation Example 1, the first lighting fixture 10a and the second lighting fixture 10b adjust according to the received control signal when the received control signal has ID: 1, 2, 3, 4 as common identification information. shine.

First, the first manipulator 30a transmits first control signals having IDs: 11, 12, 13, and 14 to the common network 3 (S31). The first control signal in step S31 is a first control signal indicating that the dimming target is the first lighting fixture 10a for the first control device 50a and the second control device 50b. The first control device 50a and the second control device 50b receive the first control signal transmitted in step S31 via the common network 3 .

Next, based on the ID, the first control device 50a determines that the dimming target of the received first control signal is the first lighting fixture 10a, and IDs of the first control signals: 11, 12, 13 , 14 are converted into IDs: 1, 2, 3, 4 (S32). Then, the first control device 50a transmits the first control signal converted to ID: 1, 2, 3, 4 to the first individual network 2a (S33). The first lighting fixture 10a receives the first control signal transmitted in step S33 via the first individual network 2a.

Since the received first control signal has IDs: 1, 2, 3, and 4, the first lighting fixture 10a reads the dimming content indicated by the received first control signal and emits light according to the first control signal. Light is dimmed (S34). Thereby, the first lighting fixture 10a is dimmed according to the operation of the first operating device 30a.

Based on the ID, the second control device 50b determines that the dimming target of the received first control signal is the first lighting fixture 10a, and discards the first control signal (S35). That is, the second control device 50b does not transmit the received first control signal to the second individual network 2b. This reduces the amount of communication in the second individual network 2b.

The second operation device 30b also transmits second control signals having IDs: 21, 22, 23, and 24 to the common network 3 (S41). The second control signal in step S41 is a second control signal indicating that the dimming target is the second lighting fixture 10b for the first control device 50a and the second control device 50b. The first control device 50a and the second control device 50b receive the second control signal transmitted in step S41 via the common network 3 .

Next, the second control device 50b determines that the dimming target of the received second control signal is the second lighting fixture 10b based on the IDs, and the IDs of the second control signals: 21, 22, 23 , 24 are converted into IDs: 1, 2, 3, 4 (S42). Then, the second control device 50b transmits the second control signal converted to ID: 1, 2, 3, 4 to the second individual network 2b (S43). The second lighting fixture 10b receives the second control signal transmitted in step S43 via the second individual network 2b.

Since the received second control signal has ID: 1, 2, 3, 4, the second lighting fixture 10b reads the dimming content indicated by the received second control signal and emits light according to the second control signal. Light is dimmed (S44). Thereby, the second lighting fixture 10b is dimmed according to the operation of the second operating device 30b.

Based on the ID, the first control device 50a determines that the dimming target of the received second control signal is the second lighting fixture 10b, and discards the second control signal (S45). That is, the first control device 50a does not transmit the received second control signal to the first individual network 2a. This reduces the traffic in the first individual network 2a.

Further, the first operating device 30a transmits first control signals having IDs: 21, 22, 23, 24, and the second operating device 30b transmits second control signals having IDs: 11, 12, 13, 14. By doing so, the lighting fixtures to be dimmed by the operation device are replaced with those in FIG. 7 . That is, the second lighting fixture 10b is dimmed according to the operation of the first operating device 30a, and the first lighting fixture 10a is dimmed according to the operation of the second operating device 30b. Therefore, in the lighting system 100, the first operation device 30a and the second operation device 30b can be operated in such a manner that the lighting fixtures to be dimmed are exchanged, that is, so-called cross operation. Also, in that case, the first control signal is not transmitted to the first individual network 2a, and the second control signal is not transmitted to the second individual network 2b. Therefore, the amount of communication in the first individual network 2a and the second individual network 2b is reduced.

As described above, the first control signal from the first manipulator 30a is transmitted to the first lighting fixture 10a and the second lighting fixture 10b via the common network 3 . That is, even if a LAN cable or the like is not exclusively installed between the first operating device 30a and each of the first lighting device 10a and the second lighting device 10b, the first operating device 30a can be used for dimming. A single control signal can be sent to both the first lighting fixture 10a and the second lighting fixture 10b. Therefore, even if wiring such as a LAN cable is not switched, the first operation unit 30a can dim both the first lighting fixture 10a and the second lighting fixture 10b.

Also, the first control signal for dimming the second lighting fixture 10b is not sent by the first control device 50a to the first individual network 2a. This reduces the traffic in the first individual network 2a. Also, the second control signal from the second manipulator 30b has the same effect as the first control signal from the first manipulator 30a.

[effect]
As described above, the lighting system 100 is connected to the first individual network 2a and installed in the first space 1a, and the first lighting fixture 10a is connected to the second individual network 2b and connected to the first space 1a. and a second lighting fixture 10b installed in a different second space 1b. The lighting system 100 further transmits a first control signal for dimming the first lighting fixture 10a or the second lighting fixture 10b to the common network 3 between the first individual network 2a and the second individual network 2b. A first operating device 30a is provided. The lighting system 100 further includes a first control device 50a that receives a first control signal via the common network 3 and determines whether or not to transmit the received first control signal to the first individual network 2a. Prepare. The first control device 50a transmits the first control signal to the first individual network 2a when determining that the dimming target of the received first control signal is the first lighting fixture 10a. The first control device 50a does not transmit the first control signal to the first individual network 2a when determining that the dimming target of the received first control signal is the second lighting fixture 10b.

Thereby, the first control signal from the first manipulator 30a is transmitted to the first lighting fixture 10a and the second lighting fixture 10b via the common network 3 . That is, even if a LAN cable or the like is not exclusively installed between the first operating device 30a and each of the first lighting device 10a and the second lighting device 10b, the first operating device 30a can be used for dimming. A single control signal can be sent to both the first lighting fixture 10a and the second lighting fixture 10b. Therefore, even if wiring such as a LAN cable is not switched, the first operation unit 30a can change the lighting fixture to be dimmed. Also, the first control signal for dimming the second lighting fixture 10b is not sent by the first control device 50a to the first individual network 2a. This reduces the traffic in the first individual network 2a.

Therefore, the lighting system 100 can easily switch the lighting fixtures to be dimmed by the operation unit, and can reduce the communication load.

Also, for example, the first operation device 30a receives an operation to select a lighting fixture to be dimmed, and transmits a first control signal for dimming the selected lighting fixture.

As a result, the lighting fixtures to be dimmed can be switched only by the first operation device 30a receiving an operation for selecting the lighting fixtures to be dimmed from the user or the like.

Also, for example, the first control signal has identification information for identifying a dimming target, and the first control device 50a outputs the first control signal based on the received identification information of the first control signal. Determine the dimming target.

Thereby, the first control device 50a can use the identification information to determine whether or not to transmit the control signal.

Further, for example, when the received control signals of the first lighting device 10a and the second lighting device 10b respectively have common identification information common to the first lighting device 10a and the second lighting device 10b as identification information. Then, it dims based on the received control signal. When the received first control signal has identification information indicating the first lighting fixture 10a as a dimming target, the first control device 50a converts the identification information into common identification information to sending a first control signal to

Thereby, the first control signal having the common identification information is transmitted to the first lighting fixture 10a via the first individual network 2a. Also, the first lighting fixture 10a and the second lighting fixture 10b dim the emitted light according to the control signal having the same common identification information. Therefore, the lighting system 100 can unify settings related to control signals for lighting fixtures installed in different spaces, which facilitates setting, maintenance, and the like.

Further, for example, the lighting system 100 further includes a second controller 30b that transmits a second control signal for dimming the first lighting fixture 10a or the second lighting fixture 10b to the common network 3. The first control device 50a also receives the second control signal via the common network 3 . The first control device 50a transmits the second control signal to the first individual network 2a when determining that the dimming target of the received second control signal is the first lighting fixture 10a. The first control device 50a does not transmit the second control signal to the first individual network 2a when determining that the dimming target of the received second control signal is the second lighting fixture 10b.

Thereby, the second control signal from the second operation device 30b is transmitted to the first lighting fixture 10a and the second lighting fixture 10b via the common network 3 . That is, even if a LAN cable or the like is not exclusively installed between the second operating device 30b and each of the first lighting device 10a and the second lighting device 10b, the second operating device 30b can be used for dimming. 2 control signals can be sent to both the first lighting fixture 10a and the second lighting fixture 10b. Also, the second control signal for dimming the second lighting fixture 10b is not sent to the first individual network 2a by the first control device 50a. Therefore, the amount of communication in the first individual network 2a is reduced. Therefore, the lighting system 100 can further reduce the communication load.

Further, for example, the lighting system 100 receives a first control signal via the common network 3, and a second control device that determines whether or not to transmit the received first control signal to the second individual network 2b. 50b. The second control device 50b does not transmit the first control signal to the second individual network 2b when determining that the dimming target of the received first control signal is the first lighting fixture 10a. The second control device 50b transmits the first control signal to the second individual network 2b when determining that the dimming target of the received first control signal is the second lighting fixture 10b.

Thereby, the second control device 50b does not transmit the first control signal for dimming the first lighting fixture 10a to the second individual network 2b. Therefore, the amount of communication in the second individual network 2b is reduced. Therefore, the lighting system 100 can further reduce the communication load.

The first controller 250a, the second controller 250b and the Nth controller 250n also have the function of converting the identification information of the received control signals.

The first individual network 202a is a network that connects the first lighting fixture 10a, the first operator 230a, and the first controller 250a. The second individual network 202b is a network that connects the second lighting fixture 10b, the second operation device 230b, and the second control device 250b. The Nth individual network 202n is a network that connects the Nth lighting fixture 10n, the Nth operator 230n, and the Nth controller 250n.

A second controller 250b is interposed between the common network 203 and the second individual network 202b. A second controller 250b is interposed between the common network 203 and the Nth individual network 202n. Common network 203 is not directly connected to lighting fixtures.

Next, details of the operation device and the control device will be described.

FIG. 9 is a block diagram showing the configuration of lighting system 200 according to the present embodiment.

The first operation device 230 a includes a first communication section 231 , a second communication section 236 , an operation section 32 , a selection section 33 , a control section 237 and a storage section 238 .

The first communication unit 231 is a communication interface connected to the common network 203, and transmits to the common network 203 a first control signal indicating that the dimming target is a lighting fixture different from the first lighting fixture 10a.

Specifically, the first communication unit 231 and the second communication unit 236 are communication modules (communication circuits) for wired LAN or wireless LAN communication.

The control unit 237 causes at least one of the first communication unit 231 and the second communication unit 236 to transmit a first control signal based on the operation received by the operation unit 32 and the selection unit 33 . For example, when the operation unit 32 is composed of a plurality of faders, the control unit 34 outputs a first control signal having dimming information based on the accepted fader operation and the universe number associated with the operated fader. is transmitted to at least one of the first communication unit 231 and the second communication unit 236 . The control unit 237 determines whether to transmit the first control signal to the first individual network 202 a or to the common network 203 based on the operation accepted by the selection unit 33 .

The storage unit 238 also stores information for associating the operation received by the operation unit 32 and the selection unit 33 with the identification information of the first control signal. The storage unit 238 stores, for example, information that associates the operation of the operation unit 32 with the universe number or the like of the sACN signal. The storage unit 238 also stores information that associates the lighting fixture selected by the selection unit 33 to be dimmed with the transmission destination of the first control signal. The storage unit 238 may store information that associates the operation of the operation unit 32 with the channel number or the like of the DMX signal. FIG. 10 is a diagram showing an example of information stored in the storage unit 238. As shown in FIG. FIG. 10 shows dimming target information in which the operated fader and the universe number of the first control signal are associated. For example, based on the dimming target information shown in FIG. 10, the first control signal having dimming information based on the operation of each fader is given a universe number corresponding to the dimming target received by the selection unit 33. be. FIG. 11 is a diagram showing another example of information stored in the storage unit 238. As shown in FIG. FIG. 11 shows transmission destination information in which lighting fixtures to be dimmed selected by the selection unit 33 and transmission destinations of the first control signal are associated with each other. For example, the first control signal is transmitted based on the destination information shown in FIG.

Specifically, the storage unit 238 is implemented by a volatile storage device such as SRAM or DRAM, or a non-volatile storage device such as a magnetic disk, optical disk, magneto-optical disk, semiconductor memory, or the like.

The first control device 250 a includes a first communication section 251 , a second communication section 52 , a communication control section 253 and a storage section 254 .

The first communication unit 251 is a communication interface connected to the first individual network 202a, and transmits a control signal indicating that the dimming target is the first lighting fixture 10a to the first individual network 202a. Also, the first communication unit 251 receives the first control signal from the first individual network 202a.

Specifically, the first communication unit 251 is a communication module (communication circuit) for wired LAN or wireless LAN communication.

The communication control unit 253 determines whether or not to transmit the control signal received by the second communication unit 52 to the first individual network 2a. The communication control unit 253 causes the first communication unit 51 to transmit the control signal determined to be transmitted.

For example, the communication control unit 253 determines the dimming target of the control signal based on the identification information of the received control signal.

Also, the communication control section 253 may discard the first control signal received by the first communication section 251 . In other words, the communication control unit 253 does not have to cause the common network 203 to transmit the first control signal received by the first communication unit 251 .

The communication control unit 253 is specifically implemented by a processor, microcomputer, dedicated circuit, or the like.

Specifically, the storage unit 254 is implemented by a volatile storage device such as SRAM or DRAM, or a non-volatile storage device such as a magnetic disk, optical disk, magneto-optical disk, semiconductor memory, or the like.

[Operation of operation device and control device]
Next, operations of the operating device and the control device according to the present embodiment will be described. The operations of the first manipulator 230a and the first controller 250a will be described below. Other operating devices such as the second operating device 230b and other control devices such as the second control device 250b operate in the same manner as the first operating device 230a and the first control device 250a, respectively. are omitted.

FIG. 12 is a flowchart showing an example of the operation of transmitting the first control signal by the first manipulator 230a.

First, the selection unit 33 of the first manipulator 230a receives an operation of selecting a lighting fixture to be dimmed by the first control signal (S111). For example, the user selects the first lighting fixture 10a or the second lighting fixture 10b as a dimming target.

Next, the operation unit 32 of the first operation device 230a receives an operation for dimming the lighting fixture to be dimmed (S112). For example, the user sets the dimming level by operating the operation unit 32 such as a fader.

Next, the control unit 237 of the first manipulator 230a determines whether or not the dimming target of the first control signal selected in step S111 is the first lighting fixture 10a (S113).

When the lighting fixture to be dimmed received by the selection unit 33 in step S111 is the first lighting fixture 10a (Yes in S113), the first operation unit 230a operates the operation unit 32 and the selection unit 33 based on the operation of the operation unit 32 and the selection unit 33. The first control signal obtained is transmitted to the first individual network 202a (S114). In other words, in step S114, the control unit 237 causes the second communication unit 236 to transmit the first control signal to the first individual network 202a. As a result, the first control signal whose dimming target is the first lighting fixture 10a is not transmitted to the common network 203, so the amount of communication in the common network 203 is reduced.

Further, when the lighting fixture to be dimmed and received by the selection unit 33 in step S111 is a lighting fixture different from the first lighting fixture 10a (No in S113), the first operation unit 230a changes the A first control signal including dimming information based on the operation is transmitted to the common network 203 (S115). In other words, in step S<b>115 , the control unit 237 causes the first communication unit 31 to transmit the first control signal to the common network 203 .

In steps S113 to S115, the control unit 237 refers to the dimming target information in the storage unit 238 shown in FIG. 10, for example. Then, the control unit 237 transmits a first control signal having a universe number based on the operated fader and the dimming target selected by the selection unit 33 and dimming information based on the fader operation to the first communication unit. 231 or the second communication unit 236. Also, the control unit 237 refers to the transmission destination information of the storage unit 238 shown in FIG. 11 to determine the transmission destination of the first control signal.

FIG. 13 is a flow chart showing an example of the operation when the first control device 250a receives the second control signal.

First, the second communication unit 52 of the first control device 250a receives a second control signal from the common network 203 (S121). The received second control signal is, for example, the second control signal transmitted from the second manipulator 230b in a manner similar to that shown in FIG. The communication control unit 253 causes the storage unit 254 to temporarily store the received second control signal. Next, the communication control unit 253 of the first control device 250a determines whether or not the dimming target of the received second control signal is the first lighting fixture 10a (S122). For example, the communication control unit 253 refers to the determination information in the storage unit 254 shown in FIG. 4 to determine the dimming target of the second control signal.

When the first control device 250a determines that the dimming target of the received second control signal is the first lighting fixture 10a (Yes in S122), the first control device 250a replaces the identification information of the received second control signal with the common identification information. (S123). The first control device 250a then transmits the second control signal to the first individual network 202a (S124). For example, the communication control unit 253 converts the universe number of the second control signal and causes the first communication unit 251 to transmit the second control signal to the first individual network 202a. The first lighting fixture 10a receives the second control signal and dims the emitted light according to the received second control signal.

When the first control device 250a determines that the dimming target of the received second control signal is a lighting fixture different from the first lighting fixture 10a (No in S122), the first control device 250a sends the second control signal to the first individual network 202a. No signal is transmitted (S125). In other words, in step S125, the communication control unit 253 does not cause the first communication unit 251 to transmit the received second control signal to the first individual network 202a. A lighting fixture different from the first lighting fixture 10a is, for example, a second lighting fixture 10b. The communication control unit 253 erases the second control signal stored in the storage unit 254 and discards the second control signal. This reduces the traffic in the first individual network 202a.

Note that even when the first control device 250a receives a control signal other than the second control signal from the common network 203, the same method as shown in FIG. process. Also, when the second control device 250b receives a control signal from the common network 203, the same method as that shown in FIG. 13 is used to determine the control signal and perform subsequent processing.

[Example of lighting system operation]
Next, an operation example of lighting system 200 according to the present embodiment will be described. In the operation example below, the sACN protocol is used as the communication method between the operation device and the lighting fixture. Further, the first manipulator 230a and the second manipulator 230b simultaneously transmit control signals (sACN signals) of a plurality of systems, specifically four systems. Moreover, although each operation example shows an operation related to the transmission of the control signal once, the control signal is repeatedly transmitted while the operation unit dims the lighting fixture. Further, in each operation example below, the universe number is denoted as ID.

Further, in each operation example, a first operation device 230a and a first control device 250a are interposed between the first individual network 202a and the common network 203, and the first individual network 202a and the common network 203 are separated from each other. not directly connected. The first individual network 202a is connected to the second communication unit 236 of the first operation device 230a and the first communication unit 251 of the first control device 250a, and the common network 203 is connected to the first communication unit 31 of the first operation device 230a. and the second communication unit 52 of the first control device 250a. The connection of the second individual network 202b, the common network 203, the second operation device 230b and the second control device 250b is the same as above.

(1) Operation example 1
First, operation example 1 of lighting system 200 according to the present embodiment will be described. FIG. 14 is a sequence diagram of Operation Example 1 of lighting system 200 according to the present embodiment. In operation example 1, the first lighting device 10a is dimmed by operating the first operating device 230a, and the second lighting device 10b is dimmed by operating the second operating device 230b. Further, in Operation Example 1, the first lighting fixture 10a and the second lighting fixture 10b receive control signals when the received control signals have IDs: 1, 2, 3, and 4 as common identification information. Dimming according to

First, the first manipulator 230a transmits a first control signal having IDs 1, 2, 3, and 4 to the first individual network 202a (S131). The first lighting fixture 10a and the first control device 250a receive the first control signal transmitted in step S131 via the first individual network 202a.

Since the received first control signal has IDs: 1, 2, 3, and 4, the first lighting fixture 10a reads the dimming content indicated by the received first control signal, and emits light according to the first control signal. The light is dimmed (S132). As a result, the first lighting fixture 10a is dimmed according to the operation of the first manipulator 230a.

The first control device 250a discards the received first control signal (S133). That is, the first control device 250 a does not transmit the received first control signal to the common network 203 . This reduces the amount of communication in the common network 203 .

Also, the second operation device 230b transmits a second control signal having IDs: 1, 2, 3, 4 to the second individual network 202b (S141). The second lighting fixture 10b and the second control device 250b receive the second control signal transmitted in step S141 via the second individual network 202b.

Since the received second control signal has ID: 1, 2, 3, 4, the second lighting fixture 10b reads the dimming content indicated by the received second control signal, and emits light according to the second control signal. The light is dimmed (S142). Thereby, the second lighting fixture 10b is dimmed according to the operation of the second operator 230b.

The second control device 250b discards the received second control signal (S143). That is, the second control device 250b does not transmit the received second control signal to the common network 203. FIG. This reduces the amount of communication in the common network 203 .

Although the first operation device 230a transmits the first control signal only to the first individual network 202a, the first control signal having the same content may be transmitted to the common network 203 as well. In that case, the second controller 250b receives the first control signal from the common network 203 and discards the received first control signal. Also, the second manipulator 230b may operate in the same manner as described above.

(2) Operation example 2
Next, operation example 2 of lighting system 200 according to the present embodiment will be described. FIG. 15 is a sequence diagram of Operation Example 2 of lighting system 200 according to the present embodiment. In operation example 2, the second lighting fixture 10b is dimmed by operating the first operating device 230a, and the first lighting fixture 10a is dimmed by operating the second operating device 230b. In Operation Example 2, the first lighting fixture 10a and the second lighting fixture 10b adjust according to the received control signal when the received control signal has ID: 1, 2, 3, 4 as common identification information. shine.

First, the first operating device 230a transmits a first control signal having IDs: 21, 22, 23, and 24 indicating the second lighting fixture 10b as a dimming target to the common network 203 (S151). The first control device 250a and the second control device 250b receive the first control signal transmitted in step S151 via the common network 203. FIG.

Based on the ID, the second control device 250b determines that the dimming target of the received first control signal is the second lighting fixture 10b, and sets the IDs of the first control signal: 21, 22, 23, 24. ID: Convert to 1, 2, 3, 4 (S152). Then, the second control device 250b transmits the first control signal converted to ID: 1, 2, 3, 4 to the second individual network 202b (S153). The second lighting fixture 10b receives the first control signal transmitted in step S153 via the second individual network 202b.

Next, since the received first control signal has ID: 1, 2, 3, 4, the second lighting fixture 10b reads the dimming content indicated by the received first control signal, and The emitted light is modulated according to (S154). Thereby, the second lighting fixture 10b is dimmed according to the operation of the first operating device 230a.

Based on the ID, the first control device 250a determines that the dimming target of the received first control signal is the second lighting fixture 10b, and discards the first control signal (S155). That is, the first controller 250a does not transmit the received first control signal to the first individual network 202a. This reduces the traffic in the first individual network 202a.

Further, the second operation device 230b transmits a second control signal having IDs: 11, 12, 13, and 14 indicating the first lighting fixture 10a as a dimming target to the common network 203 (S161). The first control device 250a and the second control device 250b receive the second control signal transmitted in step S161 via the common network 203. FIG.

Based on the ID, the first control device 250a determines that the dimming target of the received second control signal is the first lighting fixture 10a, and sets the IDs of the second control signals: 11, 12, 13, and 14. ID: Convert to 1, 2, 3, 4 (S162). Then, the first control device 250a transmits the second control signal converted to ID: 1, 2, 3, 4 to the first individual network 202a (S163). The first lighting fixture 10a receives the second control signal transmitted in step S163 via the first individual network 202a.

Next, since the received second control signal has IDs: 1, 2, 3, and 4, the first lighting device 10a reads the dimming content indicated by the received second control signal, and The emitted light is modulated according to (S164). Accordingly, the first lighting fixture 10a is dimmed according to the operation of the second operator 230b.

Based on the ID, the second control device 250b determines that the dimming target of the received second control signal is the first lighting fixture 10a, and discards the second control signal (S165). That is, the second controller 250b does not transmit the received second control signal to the second individual network 202b. This reduces the traffic in the second individual network 202b.

Although the first operation device 230a transmits the first control signal only to the common network 203, the first control signal having the same content may be transmitted to the first individual network 202a as well. In that case, the first controller 250a also receives the first control signal from the first individual network 202a and discards the received first control signal. Also, the second manipulator 230b may operate in the same manner as described above.

As in the operation example 1 and the operation example 2, in the lighting system 200, as in the lighting system 100, cross operation is possible in which the lighting fixtures to be dimmed by the operation device are switched. Also, the amount of communication in the first individual network 202a and the second individual network 202b is reduced.

A first control signal for dimming the first lighting fixture 10a is sent to the first individual network 202a, and a second control signal for dimming the second lighting fixture 10b is sent to the second separate network 202b. sent to. Therefore, the first control signal for dimming the first lighting fixture 10 a and the second control signal for dimming the second lighting fixture 10 b need not be transmitted to the common network 203 . This reduces the amount of communication in the common network 203 .

(3) Operation example 3
Next, operation example 3 of lighting system 200 according to the present embodiment will be described. FIG. 16 is a sequence diagram of Operation Example 3 of lighting system 200 according to the present embodiment. In operation example 3, both the first lighting fixture 10a and the second lighting fixture 10b are dimmed by the operation of the first operation device 230a. In Operation Example 3, the first lighting fixture 10a and the second lighting fixture 10b dim according to the received control signal when the received control signal has ID: 1, 2 as common identification information.

First, the first manipulator 230a transmits first control signals having IDs: 1 and 2 to the first individual network 202a, and transmits first control signals having IDs: 21 and 22 to the common network 203 (S171 ). The first control signals (4 systems) in step S171 are the first control signals (2 systems) having IDs: 1 and 2 for dimming the first lighting fixture 10a and the second control signal (2 systems) for dimming the second lighting fixture 10b. ID: 21, 22 for the first control signal (2 systems). The first lighting fixture 10a and the first control device 250a receive the first control signal having IDs: 1 and 2 transmitted in step S171 via the first individual network 202a. The second control device 250b receives, via the common network 203, the first control signal having IDs: 21 and 22 transmitted in step S171.

Although not shown, the first control device 250a receives the first control signal having IDs: 21 and 22 transmitted in step S171 via the common network 203. FIG. The first control device 250a discards the first control signals having IDs: 21 and 22 based on the IDs.

Since the received first control signal has IDs: 1 and 2, the first lighting fixture 10a reads the dimming content indicated by the received first control signal, and adjusts the emitted light according to the first control signal. It lights up (S172). As a result, the first lighting fixture 10a is dimmed according to the operation of the first manipulator 230a.

The first control device 250a discards the received first control signals having IDs: 1 and 2 (S173). That is, the first control device 250a does not transmit the received first control signals having IDs: 1 and 2 to the common network 203. FIG. As a result, the amount of communication in the common network 3 is reduced.

Further, the second control device 250b determines that the dimming target of the received first control signal is the second lighting fixture 10b based on the ID, and the ID: 21 and 22 of the first control signal are ID: 1, 2 (S174). The second control device 250b then transmits the first control signal converted to IDs 1 and 2 to the second individual network 202b (S175). The second lighting fixture 10b receives the first control signal transmitted in step S175 via the second individual network 202b.

Next, since the received first control signal has IDs: 1 and 2, the second lighting fixture 10b reads the dimming content indicated by the received first control signal, and emits light according to the first control signal. is dimmed (S176). Thereby, the second lighting fixture 10b is dimmed according to the operation of the first operating device 230a. That is, in Operation Example 3, both the first lighting fixture 10a and the second lighting fixture 10b are dimmed according to the operation of the first operation device 230a. In addition, both the first lighting fixture 10a and the second lighting fixture 10b can be dimmed by the second manipulator 230b in the same manner as the first manipulator 230a. Therefore, the second manipulator 230b can be used as a backup manipulator used when the first manipulator 230a fails.

[effect]
As described above, the first operation device 230a transmits the first control signal to the first individual network 202a when the dimming target of the first control signal is the first lighting fixture 10a.

Thereby, the first control signal for dimming the first lighting fixture 10a is sent to the first individual network 202a. Therefore, since the first control signal for dimming the first lighting fixture 10a does not have to be transmitted to the common network 203, the amount of communication in the common network 203 is reduced. Therefore, the lighting system 200 can further reduce the communication load.

Also, for example, when the dimming target of the first control signal is the first lighting fixture 10a, the first operation device 230a transmits the first control signal having the common identification information to the first individual network 202a.

Thereby, the first control signal with the common identification information is transmitted to the first individual network 202a. Therefore, since the first control signal having the common identification information need not be transmitted to the common network 203, the amount of communication in the common network 203 is reduced.

Also, for example, the first manipulator 230a simultaneously transmits a plurality of first control signals, and the plurality of first control signals includes a first control signal for dimming the first lighting device 10a and a second lighting signal. and a first control signal for dimming the fixture 10b.

Thereby, the first manipulator 230a can simultaneously dim the first lighting fixture 10a and the second lighting fixture 10b.
