The setting switch 32 includes a changeover mode switch 33, a first mode switch 36S, and a second mode switch 37S.

In this embodiment, the number of operation switches 31 is the same as the number of control circuit systems, because the number of control circuit systems is larger than the number of wall switches. If the number of wall switches is larger than the number of control circuit systems, it may be adjusted to that. However, generally, the number of control circuit systems is larger.

FIG. 2 shows the external appearance of each switch and the like provided on the panel of the operation device 3 of FIG. In addition, here, in order to facilitate the description, it is assumed that one operation terminal device 4 includes four wall switches 8 and a case where there are four operation terminal devices 4 will be described. Similarly, it is assumed that one control terminal device 5 has eight control circuit systems and three control terminal devices 5 are provided. Therefore, as shown in FIG. 2 (a), the number of control circuit systems on the panel of the controller 3 is 24.
There are individual operation switches 31. FIG. 3B shows four operation switches 31 corresponding to one operation terminal device (having four wall switches 8) 4.

FIG. 6 shows a detailed format for each operation mode of transmission signals transmitted and received between the central processing unit (FIG. 3) and the terminals (FIGS. 4 and 5) as described above.

The lighting control system of this embodiment has three modes as a transmission system: a normal mode, a parent activation mode, and a child activation mode. The normal mode is a mode in which the central processing unit 1 transmits a start signal, and if the terminal is activated, the terminal data signal is received.
The parent activation mode has three modes: control mode, monitoring mode, and child activation cancellation mode. The control mode is a mode used when data is sent from the central processing unit 1 to control a predetermined terminal (for example, the lighting load 6 is turned on or off). The monitoring mode is a mode used when monitoring the load state of each terminal such as monitoring the state of the wall switch 8. The child activation mode is a mode in which processing for activating the central processing unit 1 is performed from the side of each terminal. The child activation mode is canceled by the child activation cancellation mode of the parent activation mode.

Next, the operation of the lighting control system of the present embodiment will be described with reference to the flowchart of FIG. 7 and FIGS.

First, when the power is turned on, the central processing unit 1 initializes in step S1 and receives monitoring data in step S2. The signal transmission in this embodiment is time division multiplexing transmission,
Transmission and reception are performed in synchronization with 50 or 60 power cycles. The monitoring data reception in step S2
This is a process in which the operation data of the switch in the terminal is transmitted to the central processing unit in the child start mode and is received.

Next, in step S3, it is determined whether or not the data is normal mode switch depression data. If the received monitoring data is not the data for pressing the normal mode switch, the first monitoring is performed in step S4.
It is determined whether or not it is a mode switch signal. If it is the first mode switch signal, the first
Since the mode switch 36S has been pressed, the first flag is set in step S5. Then, the transmission data indicating that the LED 36L of the first mode switch 36S is turned on is set, and further the display corresponding to all the operation switches 31 is displayed.
Transmission data indicating that all the LEDs 34 and 35 should be turned off is set, and the data is transmitted in step S6. As a result, the LED 36L of the first mode switch 36S is turned on and all the other LEDs 34, 35, 37L are turned off.

Then, the process returns from step S6 to step S2 to receive the monitoring data again. If the operation switch 31 is pressed down here, the sequence proceeds from step S2 → S3 → S4 → S7 → S8 → S9 to step S10. In step S10, the first flag is 1
Is set, the flow branches to step S11, transmission data indicating that the LED 34 of the corresponding operation switch 31 is to be turned on is set, the memory storage position is designated, and the data is transmitted at step S6.

Next, the process returns to step S2 again to receive the monitoring data. If the second mode switch 37S is pressed here, the sequence proceeds from step S2 to S3 to S4 to S7 and branches from step S7 to S12. Here, since the first flag is set to 1, the process branches from step S12 to step S13, the second flag is set, and the L of the second mode switch 37S is set to L.
Set the transmission data to turn on the ED37L, and step S
Send at 6. As a result, the LE of the second mode switch 37S is
D37L lights up.

Then, the process returns from step S6 to step S2 to receive the monitoring data again. If the operation switch 31 is pressed down here, the sequence proceeds from step S2 → S3 → S4 → S7 → S8 to step S9. Since the second flag is set to 1 in step S9, the flow branches to step S14 to set the transmission data indicating that the LED 35 of the corresponding operation switch 31 is to be turned on, and the corresponding memory storage position of the designated channel. Store data and allocate. Then, it is transmitted in step S6.

Next, the process returns to step S2 again to receive the monitoring data. If the normal mode switch 33 is pressed here, the sequence branches from step S3 to step S15. Then, all switch display data are set, the first and second flags are reset, and the data is transmitted in step S6. This allows
Allocation is complete.

As described above, the process of steps S2 → S3 → S4 → S5 → S6 is set as the first mode of allocation setting mode, and steps S2 → S3
→ S4 → S7 → S8 → S9 → S10 → S11 → S6 Select the wall switch to be assigned. And step S2 → S3 →
The second mode is set by the processing of S4 → S7 → S12 → S13 → S6, and the channel is assigned to the wall switch by the processing of steps S2 → S3 → S4 → S7 → S8 → S9 → S14 → S6. After repeating this and making some assignments, the normal mode switch 33
Allocation ends when is pressed.

When the allocation process is not performed, that is, when the first and second flags are both 0, the operation switch 31 of the operation device 3 can be used as a switch for turning on / off the channel that is allocated in advance. Further, normally, the operation state of the wall switch 8 is monitored, and normal processing is performed in step S16 to send control data to the corresponding control terminal.

When the wall switch 8 is pressed after the allocation is performed as described above, the monitoring data is step S2 → S3 → S4 → S7.
→ S8 → S9 → S10 to step S16. Step S1
In 6, the central processing unit 1 reads out the allocation data corresponding to the wall switch 8 from the allocation data stored in the memory 11, and turns on the corresponding channel according to the allocation. As a result, the illumination load 6 of the channel assigned in advance is turned on.

[Effects of the Invention] As described above, according to the present invention, an operating device for allocating the wall switch and the control circuit system (lighting load) of the control terminal is provided, and the allocation is performed by operating the operating device. The operation is easy to understand and easy to operate. Moreover, if an indicator light corresponding to the switch is provided,
It is easy to check which channel is assigned. Furthermore, since the function of the operation switch is switched and used depending on the first mode and the second mode, the number of switches can be reduced, the operation device can be made small, and the cost can be reduced.
