As shown in FIG. 7, in the circuit management table 120a, identification information for identifying the circuit 60 and information regarding the state of 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. The “output state” is information indicating a state relating to the output of the circuit 60. For example, the current value measured by the sensor 126 is stored in the “output state”. “Abnormal state” is information indicating a state relating to an abnormality of the circuit 60. For example, in “abnormal state”, information indicating a leakage measured by the sensor 126 is stored. As an example, “1” is stored in the “abnormal state” when a leak is measured by the sensor 126. On the other hand, “0” is stored in the “abnormal state” when the sensor 126 does not measure the leakage. “Load position information” is information indicating the position of the load connected to the circuit 60.

  For example, in the example illustrated in FIG. 7, circuit ID “60-1”, output state “10”, abnormal state “0”, load position information “11”, “12”, and “14” are registered in association with each other. Yes. This information indicates that the circuit (for example, the circuit 60-1) corresponding to the circuit ID “60-1” has measured the current value “10” by the sensor 126. Further, this information indicates that the circuit 126 corresponding to the circuit ID “60-1” has not been measured for leakage by the sensor 126. Further, this information indicates that the load corresponding to the lighting device 10 or the like is connected to the circuit corresponding to the circuit ID “60-1” at the control addresses “11”, “12”, and “14”.

  Returning to FIG. 5, 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, the power supply unit 122 supplies power to the lighting device 10 connected to the circuit 60 corresponding to the relay 125 when the relay 125 is turned on in accordance with control by a relay control unit 131 described later.

  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. 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 controls opening and closing of the circuit according to control by a relay control unit 131 described later. Specifically, the relay 125 closes the connection of the circuit 60 corresponding to the relay 125 and supplies power when an instruction to turn on the relay 125 is output from the relay control unit 131. As a result, the lighting device 10 connected to the circuit 60 corresponding to the relay 125 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 corresponding to the relay 125 is turned off because no power is supplied.

  The sensor 126 measures current information regarding the current flowing through the circuit 60. Specifically, the sensor 126 measures the amount of power supplied via the branch breakers 124-1 to 124-n, that is, the amount of power supplied via the circuit 60. Specifically, the sensor 126 measures the current value of the current flowing through each circuit 60. For example, the sensor 126 measures the current value of the current flowing through the circuit 60 corresponding to the sensor 126 when the relay 125 is turned on in accordance with control by a relay control unit 131 described later.

  As an example, the sensor 126 measures the output state of the circuit 60 based on the measured current information. As one aspect, the sensor 126 measures the current value of the circuit 60 as the output state. In another example, the sensor 126 detects an abnormal state of the circuit 60 based on the measured current information.

  The relay control unit 131 controls power supply to the circuit 60. Specifically, the relay control unit 131 supplies power to the circuit 60 that transmits power to the lighting device 10. 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 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 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.

  The storage unit 132 stores various types of information in the storage unit 120. Specifically, the storage unit 132 stores, in the circuit management table 120a, current information regarding the current flowing through the circuit 60 measured by the sensor 126. For example, the storage unit 132 stores the current value of the current flowing through the circuit 60 measured by the sensor 126 in the “output state” of the circuit management table 120a in association with the identification information for identifying the circuit 60. Further, the storage unit 132 stores “1” in the “abnormal state” of the circuit management table 120a when an abnormality is measured by the sensor 126. For example, when a leakage current is measured in the circuit 60 by the sensor 126, the storage unit 132 stores “1” in the “abnormal state” of the circuit management table 120a in association with the identification information for identifying the circuit 60. In addition, the storage unit 132 stores information indicating the position of the lighting device 10 connected to the circuit 60 in “load position information” of the circuit management table 120a. For example, the storage unit 132 receives the control address of the lighting device 10 connected to the circuit 60 specified by the lighting control device 50 from the lighting control device 50, and associates the control address with the identification information for identifying the circuit 60.

As an example, the display unit 140 displays the output state or abnormal state of the circuit 60 based on the current information measured by the sensor 126 in association with the arrangement of the circuit 60. As an aspect, the display unit 140 displays the current value of the current flowing through the circuit 60 measured by the sensor 126 in association with the arrangement of the circuit 60 as the output state. In addition, the display unit 140 displays information indicating an abnormality such as an electric leakage measured by the sensor 126 in association with the arrangement of the circuit 60 as an abnormal state.

For this reason, the distribution board 100 can easily grasp the position of a circuit through which a normal current flows or a circuit through which an abnormal current flows. Further, the distribution board 100 can easily determine whether or not the amount of current flowing through each circuit 60 is appropriate for the allowable capacity. For this reason, for example, when the amount of current flowing through the circuit 60 exceeds the allowable capacity, the distribution board 100 prompts another circuit 60 with a sufficient capacity to change the load of the lighting device 10 or the like. Can do.

  Moreover, since the distribution board 100 can display the output state or abnormal state of the circuit in association with the arrangement of the circuit, the position of the circuit and its state can be easily grasped. For this reason, the distribution board 100 can make it easy for an administrator to know at which position a circuit is abnormal, so that it is possible to easily identify a failure location.
