  Next, the operation of the illumination control system will be described. For the operation of dimming control of the luminaire 4 so as to keep the surface of the floor 201 that is the illumination target part at a constant target illuminance, the illuminance sensor terminal 2 is installed near the surface of the floor 201, and the vicinity of the surface of the floor 201 Is measured by the illuminance sensor 21. The electrical signal of the measured illuminance is input from the illuminance sensor 21 to the central processing unit 26, and the central processing unit 26 calculates the value of the measured illuminance. The calculated measurement illuminance value is transmitted to the dimming terminal 3 via the wireless communication unit 27.

The dimming terminal 3 always transmits the received measured illuminance value and the dimming rate value transmitted to the luminaire 4 to the control device 5 via the transmission line 10.

  Next, based on the lighting control state of the lighting fixture 4 by the control apparatus 5, the control operation | movement of lighting of the lighting fixture 4 and light extinction is demonstrated. As described above, the control device 5 receives the value of the dimming rate transmitted from the dimming terminal 3 to the lighting fixture 4. When the value of the received dimming rate is smaller than the predetermined dimming rate stored in advance in the memory unit 53, the surface of the floor 201 is made to have a sufficient illuminance by outside light without turning on the lighting fixture 4. It is thought that it can be obtained at. The preset dimming rate stored in the memory unit 53 is compared with the dimming rate acquired from the dimming terminal 3, and the dimming acquired from the predetermined dimming rate When the value of the rate is small, the remote control unit 52 performs control to turn off the lighting fixture 4.

Further, the central processing unit 26 calculates the value of the measured illuminance using the electrical signal input from the illuminance sensor 21 and the arithmetic expression corrected by the correction value.

  Next, an operation for setting the target illuminance will be described. When the operation switch 103 for setting the target illuminance is pressed, the current target illuminance is displayed on the display unit 101. The displayed target illuminance value can be changed using the UP key and DOWN key of the operation switch 104. When the operation switch 105 for determining is pressed after changing to a predetermined value, the changed target illuminance value is transmitted to the central processing unit 26 and the target illuminance value is changed. When receiving a change in the target illuminance value from the target illuminance input unit 24, the central processing unit 26 transmits the target illuminance value to the dimming terminal 3 via the wireless communication unit 27.

When the switch on the ON side is pressed by the operation switch 106 for turning off and lighting, a command for turning on the lighting fixture 4 is transmitted from the control setting input unit 25 to the central processing unit 26. When the central processing unit 26 receives the lighting command, the central processing unit 26 transmits a command for lighting the corresponding lighting fixture 4 to the dimming terminal 3 via the wireless communication unit 27. When the dimming terminal 3 receives the command to turn on, the dimming terminal 3 transmits a command to turn on the lighting fixture 4 to the relay terminal 7 connected to the corresponding lighting fixture 4 through the transmission line 10. When the relay terminal 7 receives the lighting command, the relay terminal 7 can turn on the connected lighting fixture 4 by turning on the built-in relay.

  Further, when the switch on the OFF side is pressed by the operation switch 106 for turning off and lighting, a command for turning off the lighting fixture 4 is transmitted from the control setting input unit 25 to the central processing unit 26. When the central processing unit 26 receives the command to turn off, the central processing unit 26 transmits a command to turn off the corresponding lighting fixture 4 to the dimming terminal 3 via the wireless communication unit 27. When the dimming terminal 3 receives the command to turn off, the dimming terminal 3 transmits a command to turn off the lighting fixture 4 to the relay terminal 7 connected to the corresponding lighting fixture 4 via the transmission line 10. When the relay terminal 7 receives the instruction to turn off, the relay terminal 7 can turn off the built-in relay and turn off the connected lighting fixture 4.

The operation switch 107 has an input switch for month, day, hour, and minute, and the date and time of turning off and lighting can be confirmed and set on the display unit 101. The lighting fixture 4 can be turned off and on multiple times a day. In addition, when there are a plurality of lighting fixtures 4 managed by the illuminance sensor terminal 2, the display unit 101 selects the lighting fixture 4 to be controlled and changes the schedule setting for turning on and off.

Accordingly, it is possible to measure the accurate illuminance on the surface of the floor 201 without installing the illuminance sensor 21 at a place away from the floor 201 such as the ceiling 202. The dimming terminal 3 acquires the measured illuminance value from the illuminance sensor terminal 2 using wireless communication, and the dimming terminal 3 is a dimming control target so that the measured illuminance value becomes a predetermined target illuminance value. Since the dimming rate of a certain luminaire 4 is controlled, the dimming terminal 3 can be installed at a position away from the illuminance sensor terminal 2, and the measured illuminance is more accurate than the illuminance sensor terminal 2. The value can be obtained. As a result, an accurate measured illuminance value of the surface of the floor 201 can be acquired, and dimming control with the surface of the floor 201 as a predetermined target illuminance can be accurately performed.

Further, since the control device 5 includes a remote control unit 52 that controls the lighting device 4 to be turned on and off by comparing the dimming rate with a predetermined dimming rate, the dimming rate is a predetermined dimming rate. In the following cases, it is determined that the illuminance is sufficiently ensured by external light or the like, and the lighting apparatus 4 can be controlled to be turned off, so that the lighting control system 1 capable of reducing energy consumption is provided. be able to.
