  Therefore, by displaying the operation button display parts 12 and 13 of the wall switch 4 in different colors according to the on / off state in this way, the user can see at a glance which area of the lighting fixture is on / off. Can recognize.

  Display data of the operation button display units 12 and 13 constituting the operation screen 4A of the wall switch 4 is transmitted from the CPU 2a of the central processing unit 2. Then, the wall switch 4 receives this display data, and displays the plurality of operation button display sections 12 and 13 on the operation screen 4A based on the received display data.

  The wall switch 4 has a well-known touch panel type switch structure, and includes an input device such as a CPU, a ROM, a RAM, a touch pad for performing display control based on at least the received display data, and further, It has a communication function with CPU2a which is a control part.

  Next, a control example of the central processing unit that performs display control of the wall switch 4 having the above configuration will be described with reference to FIGS. FIG. 6 is a flowchart showing an example of control in the CPU of the central processing unit in FIG. 1, and FIG. 7 is a flowchart showing a routine for calculating the integrated power consumption in the CPU of the central processing unit in FIG.

  The CPU 2a of the central processing unit 2 always executes the routine shown in FIG. 6 read from the ROM 2b. That is, the CPU 2a determines whether or not there is a change in the operation by the wall switch 4 that is a monitoring terminal or the schedule information stored in the ROM 2b in the process of step S100.

  In this case, if the CPU 2a receives the operation signal from the wall switch 4 or determines that the schedule information has changed, the CPU 2a moves the process to step S101. The determination process in step S100 is continued.

  In the process of step S101, the CPU 2a generates a control signal for lighting the designated group of lighting devices at the designated dimming rate, that is, the preset dimming rate stored in the ROM 2b, This control signal is output to the control terminal S of the group based on the received on / off operation signal.

  In this case, if the all-on switch 12a is turned on, the CPU 2a uses the control information of the luminaires stored in the ROM 2b to generate a control signal so that all previous luminaires are dimmed. And output. The dimming state of all the previous lighting fixtures is the dimming state of all the lighting fixtures turned on by the all-on switch 12a, and all the lighting fixtures immediately before being turned off by the OFF operation of the all-off switch 12b. Dimming state.

  Or CPU2a sets the light control rate of all the some lighting fixtures to the predetermined limit value memorize | stored in ROM2b, and produces | generates and outputs the control signal which becomes this set predetermined limit value.

  Note that, depending on the setting, the CPU 2a generates and outputs a control signal for lighting only the lighting fixtures in the group with the dimming rate equal to or higher than the predetermined limit value, and outputs the control signal of the lighting fixture with the dimming rate less than the predetermined limit value. It is also possible to control the group so that it does not light up. In this case, the CPU 2a performs control so that it does not light even if it is turned on by an individual operation button.

  After the output control of the control signal, the CPU 2a displays the on / off display of the operation button, the dimming rate, or the power consumption corresponding to the control signal output in step S101 by the processing in the subsequent step S102. Next, the display data generation processing of the operation button display units 12 and 13 of the wall switch 4 is performed.

  Thereafter, the CPU 2a outputs the generated display data of the wall switch 4 to the wall switch 4 through the transmission line 3 in the subsequent process of step S103. As a result, the wall switch 4 receives the display data output via the transmission line 3 and performs display based on the received display data, so that the current control state is displayed on the screen of the wall switch 4. The operation screen 4A having the operation button display units 12 and 13 shown in FIG. 3 is displayed.

  Thereafter, the CPU 2a returns the process to step S100, and continues the process of step S100 until there is an operation by the wall switch 4 or a change in the schedule.

  Further, the CPU 2a of the central processing unit 2 always executes the calculation processing routine of the power consumption amount and the consumption power consumption amount shown in FIG. 7 while executing the processing routine shown in FIG.

  That is, the CPU 2a detects the current output status of all lighting fixtures using the control information such as the control signal in the process of step S200, and in the subsequent processing of step S201, detects all the detected lighting fixtures. Using the output state, the power consumption and the integrated power consumption are calculated, the calculated power consumption and the integrated power consumption data are stored in the ROM 2b, and the display data of the wall switch 4 is appropriately created. Used when.

  The accumulated power consumption data is, for example, data that is calculated every hour, every day, or every month, and may be set as needed.

  As described above, in the wall switch 4 according to the present embodiment, the operation button display units 12 and 13 that are touch panel type operation buttons communicate with the CPU 2a of the control unit, whereby a plurality of lighting fixtures for each area are provided. It is possible to display the dimming rate or power consumption of a plurality of lighting fixtures for each area while switching to at least two display states of an on state and an off state.

  With this configuration, in the wall switch 4 of the present embodiment, it is possible to turn on / off the lighting fixtures in groups for each of the 20 areas, so there is no need to provide a wall switch that is a separate monitoring terminal, Costs in the lighting control system can be reduced.

  Moreover, since the dimming rate or power consumption of a plurality of lighting fixtures for each area is displayed on the operation button display sections 12 and 13 of the wall switch 4, the control information of the lighting fixtures for each area is notified to the user. Therefore, it greatly contributes to energy saving.

  Further, the wall switch 4 is displayed in different colors on the operation button in the on state including the all-on switch 12a and the operation button in the off state including the all-off switch 12b. Therefore, according to this embodiment, it is possible to turn on / off lighting fixtures for a plurality of groups without adding a plurality of monitoring terminals, and for each group. By displaying the dimming rate or power consumption of the lighting fixture, an inexpensive monitoring terminal capable of saving energy and an illumination control system using the monitoring terminal can be realized.

  In the present embodiment, the control terminal S is configured so that, for example, a four-circuit lighting fixture can be connected. However, the control terminal S is not limited to this. For example, the control terminal S is configured so that an eight-circuit lighting fixture can be connected. It may be.

  In the present embodiment, the operation button display unit 13 of the wall switch 4 is configured to include the operation buttons 13A to 13T corresponding to 20 areas, but is not limited thereto. The number of areas and the number of operation buttons may be set as appropriate according to the layout of the floor.

  The present invention is not limited to the above-described embodiments and modifications, and various changes and modifications can be made without departing from the scope of the present invention.
