  FIG. 4 is a diagram illustrating an example of information stored in the address management table 53a according to the first embodiment. As shown in FIG. 4, in the address management table 53a, control addresses and information related to the lighting device 10 are registered in association with each other.

  Here, the “control address” is a control address used when controlling the lighting device 10 indicated by the associated identification information, that is, a DMX address. “Identification information” is information for identifying each of the lighting devices 10-1 to 10-n, and is, for example, a UID. “Appliance information” is information indicating the characteristics of the device such as the type of the lighting device 10 and the power consumption. “Connection status” is information regarding a circuit to which the lighting device 10 is connected.

  For example, in the example illustrated in FIG. 4, control address “11”, identification information “UID1”, appliance information “spotlight, 1 kW”, and connection status “60-1” are registered in association with each other. This information indicates that the control address “11” is set for the lighting device indicated by the identification information “UID1”. In addition, this information is a “spotlight” in which the illumination device 10 (for example, the illumination device 10-1) indicated by the identification information “UID1” has power consumption “1 kW”, and the circuit corresponding to the wiring “60-1”. Indicates that it is connected. In the example illustrated in FIG. 4, the control address “14” indicates that the lighting device 10 is not connected to the circuit.

  FIG. 5 is a diagram illustrating an example of information stored in the timing management table 53b according to the first embodiment. As shown in FIG. 5, time and a control address are registered in the timing management table 53b in association with each other.

  Here, “time” is a time indicating whether the lighting device 10 is turned on or off. For example, the “time” stores an elapsed time from the start of a performance performed on the stage where the lighting device 10 is installed. The “control address” is information indicating whether the lighting device 10 corresponding to the DMX address is turned on or off, which is used when controlling the lighting device 10 indicated by the associated identification information. For example, “1” is stored in the “control address” when the lighting device 10 corresponding to the control address is turned on. Also, “0” is stored in the “control address” when the lighting device 10 corresponding to the control address is turned off.

  For example, in the example shown in FIG. 5, the time “00:00 to 00:01”, the control address 11 “1”, the control address 12 “0”, and the control address 13 “0” are registered in association with each other. This information indicates that the lighting device 10 corresponding to the control address “11” is turned on in the time period from “00:00 to 00:01” after the start of the performance. In addition, this information indicates that the lighting device 10 corresponding to the control address “12” is turned off in the time zone of “00:00 to 00:01” from the start of the performance. In addition, this information indicates that the lighting device 10 corresponding to the control address “13” is turned off in the time period from “00:00 to 00:01” after the start of the performance. Further, in the example shown in FIG. 5, the lighting device 10 corresponding to the control addresses “11”, “12”, and “13” in the time period from “00:02 to 00:03” from the start of the performance. Is turned off.

  Returning to FIG. 3, the description will be continued. The display unit 54 is a display device that displays information about a fader that accepts an operation on each of the lighting devices 10-1 to 10-n. For example, the display unit 54 is realized by a liquid crystal monitor, a touch panel, or the like.

  The control unit 55 is a device that controls each of the lighting devices 10-1 to 10-n. As the control unit 55, an electronic circuit such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), or an integrated circuit such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Gate Array) can be employed. The control unit 55 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. The control unit 55 functions as various processing units by operating various programs. Specifically, the control unit 55 controls each of the lighting devices 10-1 to 10-n using the control address. For example, the control unit 55 includes an output unit 56.

  The output unit 56 outputs various information. Specifically, when any one of the faders accepts the operation, the output unit 56 generates a control signal indicating the operation content and a control address associated with the fader number of the fader that accepted the operation, The generated control signal is output to the lighting device 10. As a result, the lighting device 10 associated with the fader that accepted the operation controls the lighting mode according to the control signal.

  The output unit 56 outputs a control signal for controlling the relay 125 included in the distribution board 100. Specifically, the output unit 56 outputs to the relay 125 a control signal that opens the circuit 60 in which all the connected lighting devices 10 are stopped, and at least one of the connected lighting devices 10 operates. A control signal for closing the circuit 60 in a state is output to the relay 125. In other words, the output unit 56 outputs a control signal that opens the circuit 60 when no lighting device 10 connected to the circuit 60 is used in order to reduce standby power. For example, for each circuit, the output unit 56 determines whether the lighting device 10 connected to the circuit 60 is in a stopped state or an operating state, and the circuit 60 in which all the lighting devices 10 connected to the circuit 60 are in a stopped state. Is output to the relay 125. As an example, the output unit 56 determines whether the lighting device 10 connected to the circuit 60 is in a stopped state or an operating state for each predetermined period, and outputs a control signal to the relay 125.

  Note that the output unit 56 determines, for example, whether the lighting device 10 connected to the circuit 60 is in a stopped state or an operating state from a control signal for each circuit. As one aspect, the output unit 56 outputs a control signal for opening the circuit 60 to the relay 125 when all the control signals to the lighting apparatus 10 connected to the circuit 60 indicate stop. On the other hand, when at least one of the control signals to the lighting device 10 connected to the circuit 60 indicates an operation, the output unit 56 outputs a control signal for closing the circuit 60 to the relay 125. In addition, the output unit 56 outputs information related to the control address indicating the position of the lighting device 10 connected to the circuit 60 to the distribution board 100.

[Configuration of distribution board]
Next, an example of a functional configuration of the distribution board 100 according to the first embodiment will be described with reference to FIG. FIG. 6 is a block diagram illustrating an example of a functional configuration of the distribution board 100 according to the first embodiment. As shown in FIG. 6, the distribution board 100 according to the first embodiment includes a communication unit 110, a storage unit 120, a display unit 121, a power supply unit 122, a main breaker 123, and branch breakers 124 (124-1 to 124-). n), a relay 125 (125-1 to 125-n), and a control unit 130.

  The communication unit 110 is a communication device that controls communication with the illumination control device 50, and is realized by, for example, a NIC or the like. Specifically, the communication unit 110 has a communication function for transmitting and receiving information to and from the lighting control device 50. For example, the communication unit 110 performs communication for receiving a control signal for controlling the relay 125 from the lighting control device 50.

  The storage unit 120 is realized by a storage device such as an HDD, an SSD, a flash memory, or a RAM. Specifically, the storage unit 120 stores a circuit management table 120a and a non-use time management table 120b. Information regarding each circuit 60-1 to 60-n is registered in the circuit management table 120a. In the unused time management table 120b, information related to a time zone when the lighting device 10 is not used is registered. This point will be described with reference to FIGS.

  FIG. 7 is a diagram illustrating an example of information stored in the circuit management table 120a according to the first embodiment. As shown in FIG. 7, in the circuit management table 120a, identification information for identifying the circuit 60 and information regarding the position of the load connected to the circuit 60 are registered in association with each other.

  Here, the “circuit ID” is identification information for identifying each of the circuits 60-1 to 60-n. For example, the “circuit ID” stores a character string such as a unique alphanumeric character individually assigned to each circuit. “Load position information” is information indicating the position of the load connected to the circuit 60. For example, the “load position information” stores a control address indicating the position of the lighting device 10 connected to the circuit 60. As an example, the control address of the lighting device 10 transmitted from the lighting control device 50 is stored in the “load position information”.

  For example, in the example illustrated in FIG. 7, circuit ID “60-1” and load position information “11”, “12”, and “13” are registered in association with each other. In this information, the circuit corresponding to the circuit ID “60-1” (for example, the circuit 60-1) has a load such as the lighting device 10 connected to the control addresses “11”, “12”, and “13”. Indicates that

  Next, the nonuse time management table 120b will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of information stored in the non-use time management table 120b according to the first embodiment. As illustrated in FIG. 8, a time when the lighting device 10 is not used is registered in the non-use time management table 120b. Here, “non-use time” is a time when the lighting device 10 is not used. For example, “non-use time” stores a time zone outside business hours when the lighting device 10 is not used, such as nighttime or a closed day. For example, in the example shown in FIG. 8, the time zone “2016/3/5 23:00 to 07:00” indicates that the lighting device 10 is not used.

  Returning to FIG. 6, the display unit 121 displays various types of information. Specifically, the display unit 121 displays information regarding the circuit 60. More specifically, the display unit 121 reads and displays information related to the circuit 60 stored in the circuit management table 120a. In addition, the display unit 121 receives an operation for controlling the power supply of the circuit 60 by the relay 125. For example, the display unit 121 receives an operation of selecting an object corresponding to the circuit 60 displayed on the screen to switch the relay 125 that supplies power to the circuit 60 on or off. The display unit 121 is realized by a display device such as a liquid crystal monitor or a touch panel, for example.

  The power supply unit 122 is a power supply device that supplies power. Specifically, the power supply unit 122 supplies power to each of the lighting devices 10-1 to 10-n. For example, when the relay 125 is turned on in accordance with control by a relay control unit 131 described later, the power supply unit 122 starts supplying power to the lighting device 10 connected to the circuit 60 corresponding to the relay 125.

  The main breaker 123 collectively controls the power supply of all the circuits 60 included in the distribution board 100. The main breaker 123 cuts off the power supply when the amount of current flowing through all the circuits 60 exceeds a predetermined value. For example, the main breaker 123 cuts off the power supply when the total value of the currents supplied via the respective wires exceeds a predetermined threshold value due to an increase in power consumption, electric leakage, or the like.

  The branch breaker 124 controls the power supply of the circuit 60 for each circuit in accordance with control by a relay 125 described later. The branch breaker 124 cuts off the power supply when the amount of current flowing through each circuit 60 exceeds a predetermined value. For example, the branch breaker 124 cuts off the power supply of the circuit 60 when the current flowing through the circuit 60 exceeds a predetermined threshold value set in advance.

  The relay 125 performs control to supply power to the circuit 60 that transmits power to the lighting device 10. Specifically, the relay 125 controls the opening and closing of the circuit according to control by a relay control unit 131 described later. For example, when the relay control unit 131 outputs an instruction to turn on the relay 125, the relay 125 closes the connection of the circuit 60 corresponding to the relay 125 and supplies power. As a result, the lighting device 10 connected to the circuit 60 is turned on when power is supplied. On the other hand, when the relay control unit 131 outputs an instruction to turn off the relay 125, the relay 125 disconnects the power supply by opening the connection of the circuit 60 corresponding to the relay 125. As a result, the lighting device 10 connected to the circuit 60 is not supplied with power and is turned off.

  The relay 125 is a relay that can be remotely operated by the lighting control device 50. Thereby, for example, when the relay 125 receives a control signal for closing the circuit 60 from the lighting control device 50, the relay 125 closes the connection of the circuit 60 and supplies power. In addition, when the relay 125 receives a control signal for opening the circuit 60 from the lighting control device 50, the relay 125 opens the connection of the circuit 60 and stops supplying power.

  The control unit 130 is a device that controls each of the lighting devices 10-1 to 10-n. As the control unit 130, an electronic circuit such as a CPU or MPU, or an integrated circuit such as an ASIC or FPGA can be employed. The control unit 130 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. The control unit 130 functions as various processing units by operating various programs. Specifically, the control unit 130 includes a relay control unit 131 and an output unit 132.

  The relay control unit 131 controls the relay 125 included in the distribution board 100. Specifically, the relay control unit 131 controls power supply to the circuit 60 that transmits power to the lighting device 10 by controlling the relay 125. For example, the relay control unit 131 supplies power to the circuit 60 by turning on the relay 125 corresponding to the circuit 60. As an example, the relay control unit 131 supplies an electric power to the circuit 60 corresponding to the relay 125 by outputting an instruction to turn on the relay 125 to the relay 125. In addition, the relay control unit 131 stops the power supply to the circuit 60 by turning off the relay 125 corresponding to the circuit 60. For example, the relay control unit 131 outputs an instruction to turn off the relay 125 to the relay 125, thereby cutting off power supply to the circuit 60 corresponding to the relay 125.

  Further, the relay control unit 131 controls the relay 125 according to the control signal output from the illumination control device 50. Specifically, when receiving a control signal for closing the circuit 60 from the lighting control device 50, the relay control unit 131 closes the connection of the circuit 60 and supplies power. In addition, when receiving a control signal for opening the circuit 60 from the lighting control device 50, the relay control unit 131 opens the connection of the circuit 60 and stops supplying power.

  The output unit 132 outputs various types of information. Specifically, the output unit 132 generates a control signal according to an instruction from the relay control unit 131 and outputs the generated control signal to the relay 125. For example, when receiving a control signal for closing the circuit 60 from the lighting control device 50, the output unit 132 outputs a control signal for closing the connection of the circuit 60 to the relay 125. Moreover, the output part 132 outputs the control signal which opens the connection of the circuit 60 to the relay 125, when the control signal which opens the circuit 60 from the lighting control apparatus 50 is received.

  Here, the output unit 132 is not limited to outputting the control signal based on the information received from the lighting control device 50, but may output the control signal based on the state of the lighting device 10 connected to the circuit 60. Good. Specifically, the output unit 132 outputs, to the relay 125, a control signal that opens the circuit 60 in which all the connected lighting devices 10 are stopped, and at least one of the connected lighting devices 10 is illuminated. A control signal for closing the circuit 60 in which the device 10 is operating is output to the relay 125. In other words, the output unit 132 outputs a control signal based on the state of the lighting device 10 determined by the distribution board 100 instead of the lighting control device 50.

  The output unit 132 may output the control signal by referring to the circuit management table 120a and determining whether the lighting device 10 connected to the circuit 60 is in a stopped state or an operating state from the control signal for each circuit. . As one aspect, the output unit 132 outputs a control signal for opening the circuit 60 to the relay 125 when all the control signals to the lighting apparatus 10 connected to the circuit 60 indicate stop. On the other hand, the output unit 132 outputs a control signal for closing the circuit 60 to the relay 125 when at least one of the control signals to the lighting apparatus 10 connected to the circuit 60 indicates an operation. Accordingly, the distribution board 100 can control the output of the control signal alone without using the illumination control device 50.

  The control unit 130 described above may be realized by a computer having a CPU, a RAM, an EEPROM, a flash memory, and the like reading a control program registered in a predetermined recording medium and executing the read control program.

[Processing Procedure of Distribution Board According to First Embodiment]
Next, the flow of control processing by the illumination control system 1 according to the first embodiment will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of a control process in the illumination control system 1 according to the first embodiment.

  Specifically, the lighting control system 1 first checks the state of the circuit 60 that transmits power to the lighting device 10 (step S101). For example, the lighting control system 1 checks whether the lighting device 10 connected to the circuit 60 is in a stopped state or an operating state.

  And the lighting control system 1 outputs the control signal which opens the circuit in which all the connected lighting apparatuses 10 are a stop state to the relay 125 (step S103). In other words, the lighting control system 1 outputs a control signal for opening the circuit 60 to the relay 125 when all the lighting devices 10 connected to the circuit 60 are in a stopped state (step S102; Yes).

  Further, the lighting control system 1 outputs a control signal for closing the circuit 60 in which at least one of the connected lighting devices 10 is in an operating state to the relay 125 (step S104). In other words, the lighting control system 1 outputs a control signal for closing the circuit to the relay 125 when all the lighting devices 10 connected to the circuit 60 are not in the stopped state (step S102; No).

[Effect of the first embodiment]
As described above, according to the lighting control system 1 according to the first embodiment, it is possible to open a circuit in which all the connected lighting devices 10 are in a stopped state, so that standby power can be reduced. . For this reason, since the lighting control system 1 can suppress standby power even in a system in which, for example, an LED or the like is extinguished and the control circuit of the appliance operates, power consumption can be reduced. In addition, since the lighting control system 1 can close a circuit in which at least one of the connected lighting devices 10 is in an operating state, it is possible to reduce standby power without causing a problem in production or the like.

[Modification of First Embodiment]
(1. Relay control)
In the first embodiment, the lighting control system 1 outputs to the relay 125 a control signal that opens a circuit in which all connected lighting devices 10 are in a stopped state, and at least of the connected lighting devices 10. The example which outputs the control signal which closes the circuit which one is an operation state to the relay 125 was shown. Here, the lighting control system 1 may control the relay 125 when the state of the lighting device 10 is switched.

  Specifically, the lighting control system 1 controls to close the circuit 60 to which the lighting device 10 is connected a predetermined time before the control signal for switching the lighting device 10 from the stopped state to the operating state is output. A signal is output to the relay 125. This is because the lighting device 10 may take time until the operation is actually started after the power is turned on, so that the lighting device 10 is in standby by turning on the power before the lighting device 10 is turned on. . For example, the output unit 56 of the lighting control device 50 controls the circuit 60 to which the lighting device 10 is connected a predetermined time before the control signal for switching the lighting device 10 from turning off to lighting is output. Is output to the relay 125 included in the distribution board 100.

  Thereby, since the lighting control system 1 can close the circuit 60 in advance when switching the lighting device 10 from the stop state to the operation state, the lighting device 10 can be switched without time lag. For example, since the lighting control system 1 closes the circuit 60 in advance even if the lighting device 10 is a device that takes a long time from when the power is turned on to when the operation actually starts, the lighting device 10 is not delayed from a desired timing. Can be controlled.

(2. Non-use time)
In the first embodiment, the lighting control system 1 outputs to the relay 125 a control signal that opens a circuit in which all connected lighting devices 10 are in a stopped state, and at least of the connected lighting devices 10. The example which outputs the control signal which closes the circuit which one is an operation state to the relay 125 was shown. Here, the lighting control system 1 may control the relay 125 according to the time when the lighting device 10 is not used.

  Specifically, the lighting control system 1 outputs a control signal for opening the circuit 60 to the relay 125 at a predetermined time. For example, the output unit 132 of the distribution board 100 refers to the non-use time management table 120b and relays a control signal that opens all the circuits 60 when the current time is a non-use time at which the lighting device 10 is not used. It outputs to 125.

  The non-use time may be set to a time when the lighting device 10 is not used for each circuit. In this case, the output unit 132 of the distribution board 100 sends a control signal for opening the circuit 60 to the relay 125 when the current time is a non-use time in which all the lighting devices 10 connected to the circuit 60 are not used. Output.

  Thereby, since the lighting control system 1 can open the circuit 60 in the time slot | zone which does not use the illuminating device 10, it can reduce standby power. For example, the lighting control system 1 can reduce wasteful power consumption when a time zone during which the lighting device 10 is not used is known in advance, such as at night or on a holiday.

(3. Output of control signal)
In the first embodiment, the lighting control system 1 outputs to the relay 125 a control signal that opens a circuit in which all connected lighting devices 10 are in a stopped state, and at least of the connected lighting devices 10. The example which outputs the control signal which closes the circuit which one is an operation state to the relay 125 was shown. Here, the lighting control system 1 may control the timing of outputting the control signal of the lighting device 10.

  Specifically, in the lighting control system 1, the lighting control device 50 outputs a control signal for lighting the lighting device 10 after the output unit 56 outputs a control signal for closing the circuit 60. In other words, the lighting control device 50 outputs a lighting signal for the lighting device 10 after outputting a control signal for turning on the relay 125 included in the distribution board 100. In the lighting control system 1, the lighting control device 50 outputs a control signal for turning off the lighting device 10 at the same time as the output unit 56 outputs a control signal for opening the circuit 60. In other words, the lighting control device 50 simultaneously outputs a control signal for turning off the relay 125 included in the distribution board 100 and a turn-off signal for the lighting device 10.

  These points will be described with reference to FIG. FIG. 10 is an explanatory diagram for explaining a control process in the illumination control system 1 according to the modification. As illustrated in FIG. 10, the lighting control device 50 turns on the relay 125 included in the distribution board 100 before switching the dimming signal that controls the light source unit 16 included in the lighting device 10 from the turn-off signal to the lighting signal. Output relay control signal. For example, the illumination control device 50 outputs a control signal for turning on the relay 125 before the activation time of the LED fixture from the timing of outputting the lighting signal. Here, the timing of outputting the lighting signal means the timing of outputting the lighting signal with brightness exceeding 0% to the lighting device 10.

  Note that the lighting signal output by the illumination control device 50 may gradually increase the brightness from 0%. For example, when the brightness of the lighting device 10 is gradually increased, the lighting control device 50 outputs a relay control signal that turns on the relay 125 before switching the dimming signal from the turn-off signal to the lighting signal. On the other hand, when the lighting control device 50 turns on the lighting device 10 with 100% brightness at a stroke, the lighting control device 50 switches the dimming signal from the turn-off signal to the lighting signal, and at the same time, sends a relay control signal for turning on the relay 125. It may be output.

  Further, as illustrated in FIG. 10, the lighting control device 50 switches the dimming signal for controlling the light source unit 16 included in the lighting device 10 from the lighting signal to the extinguishing signal, and at the same time, the relay 125 included in the distribution board 100. Output relay control signal to turn off.

  Thereby, since the lighting control system 1 can supply electric power only when the lighting device 10 is turned on, standby power can be reduced. For this reason, for example, the lighting control system 1 can reduce the standby power of the control circuit that is generated even when the lighting device 10 is turned off, thereby saving the electricity bill and realizing an environment-friendly power supply. be able to. In addition, since the lighting control system 1 can reduce standby power, for example, as the number of connected lighting devices 10 increases, it is possible to contribute to saving of electricity bills.

  Note that the lighting control device 50 outputs a dimming signal for controlling the light source unit 16 included in the lighting device 10 when the activation time of the LED fixture is short enough not to affect the lighting delay of the lighting device 10. At the same time as switching to a lighting signal, a relay control signal for turning on the relay 125 included in the distribution board 100 may be output.

[Second Embodiment]
In said 1st Embodiment, the lighting control system 1 outputs the control signal which opens the circuit in which all the connected lighting apparatuses 10 are a stop state to the relay 125, Among the connected lighting apparatuses 10 Although the case where the control signal for closing the circuit 60 in which at least one is in the operating state is output to the relay 125 has been described, the present invention is not limited to this. Specifically, the lighting control system 1 may record various waveforms related to the circuit 60.

As an example, the voltage sensor 226 measures the occurrence of an instantaneous power failure.

  The current sensor 227 measures the current flowing through the relay 125 connected to the circuit 60. Specifically, the current sensor 227 measures the amount of power supplied to the relay 125 via each branch breaker 124-1 to 124-n, that is, the amount of power supplied via the circuit 60. More specifically, the current sensor 227 measures the current waveform of the current flowing through the relay 125 for each circuit. The current sensor 227 measures the current value of the current flowing through each circuit 60. For example, the current sensor 227 measures the current value of the current flowing through the circuit 60 corresponding to the current sensor 227 when the relay 125 is turned on according to the control by the relay control unit 131.

  The voltage recording unit 233 records information regarding the voltage. Specifically, the voltage recording unit 233 records the voltage waveform measured by the voltage sensor 226 when the instantaneous power failure is measured by the voltage sensor 226. For example, the voltage recording unit 233 records a voltage waveform when an instantaneous power failure is detected.

  The current recording unit 234 records information related to current. Specifically, the current recording unit 234 records the current waveform measured by the current sensor 227 when the control signal of the relay 125 and the state of the relay 125 do not match. For example, the current recording unit 234 detects a state of the relay 125 by inputting a control signal to the relay 125, and records a current waveform flowing through the relay 125 when the state of the relay 125 does not match with the control signal.

  The distribution board 200 records the voltage waveform measured by the voltage sensor 226 when the instantaneous power failure is measured by the voltage sensor 226 (step S202; Yes) (step S203). On the other hand, the distribution board 200 does not record the voltage waveform measured by the voltage sensor 226 when the power supply instantaneous interruption is not measured by the voltage sensor 226 (step S202; No).

  Moreover, the distribution board 200 measures the electric current which flows into the relay 125 connected to the circuit 60 (step S204). For example, the distribution board 200 measures the current waveform of the current flowing through the relay 125 for each circuit.

  The distribution board 200 records the current waveform measured by the current sensor 227 (step S206) when the control signal of the relay 125 and the state of the relay 125 do not match (step S205; Yes).
