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 setting flag is 1. The setting flag is a flag which is set when the allocation setting process is performed by pressing the setting switch 33 of the operation unit 3 and reset when the allocation setting process is completed, and indicates whether or not the allocation setting mode is set. If the setting flag is not 1, it is determined in step S4 whether the received monitoring data is a setting switch signal. If it is a setting switch signal, it means that the setting switch 33 has been pressed for allocation, and therefore, the setting flag is set in step S5. Then, in step S6, the transmission data for turning on the setting switch LED 37 is set, and in step S7, all the display LEDs 34, 35 corresponding to all the operation switches 31 and the display LEDs 36 corresponding to all the channel designation switches 32 are turned off. The transmission data is set and transmitted in step S8. As a result, the LED 37 of the setting switch 33 lights up, and the other LEDs
All 34, 35 and 36 are turned off.

Then, the process returns to step S8 or step S2 to receive the monitoring data again. Since the setting flag is set to 1 here, the process branches from steps S3 to S9 to determine whether the received signal is a setting switch signal. If it is not the setting switch signal, it is determined in step S10 whether it is an operation switch signal. If it is an operation switch signal, the allocation flag of the corresponding operation switch in the memory 11 inside the central processing unit 1 is set in step S11. Then, in step S12, transmission data indicating that the display LED 34 of the corresponding operation switch 31 is turned on is set, and the transmission data is transmitted in step S8.

Next, the process returns to step S2 again to receive the monitoring data. Since the setting flag is set to 1 here, the process branches from step S3 to step S9 to determine whether or not the setting switch signal has been received. If it is not the setting switch signal, it is determined in step S10 whether or not the operation switch signal is received. If not an operation switch signal, step
In S13, it is determined whether the allocation flag is set in the memory 11 of the central processing unit 1. If the allocation flag is not set, the process returns to step S2. Here, since the allocation flag is set in step S11,
The process branches from step S13 to step S14. In step S14, it is determined whether the channel designation switch signal has been received. Step if not channel designated switch signal
Return to S2. When the channel designation switch 32 is pressed, the process branches from step S14 to step S15, and the corresponding channel designated by the channel designation switch 32 is assigned to the assignment memory of the corresponding operation switch 31. Then, the data for lighting the display LED 36 corresponding to the pressed channel designation switch 32 is set as the transmission data, and is transmitted in step S8 As described above, steps S2 → S3 → S9 → S10 → S11 → S12 → S
The operation switches are assigned by the processing in step 8, and step S2
→ S3 → S9 → S10 → S13 → S14 → S15 → S8 Specify the applicable channel to be assigned to the applicable operation switch by the process. Repeat this to make some assignments, and then
When 33 is pressed, the monitoring data is received in step S2. Since the setting flag is set to 1, the process branches from step S3 to step S9, where it is determined whether or not the setting switch signal has been received. Since the setting switch 33 is pressed, the process branches from step S9 to step S16.
The allocation is finished here. Then, the transmission data indicating the display state for all the switches is set, the setting flag and the allocation flag are reset, the transmission is performed in step S8, and the process returns to step S2 again. By the above, allocation of some channels to the operation switch 31 (wall switch) is completed.

When the allocation process is not performed, that is, when the setting flag is 0, the operation switch 31 of the operation device 3 can be used as a switch for turning on / off the channel which is allocated in advance. Further, normally, the operation state of the wall switch 8 is monitored, and normal processing is performed in step S17 to send control data to the corresponding control terminal.

That is, when the wall switch 8 is pressed after the allocation is performed as described above, the monitoring data is received in step S2 and reaches step S17 via steps S3 and S4. In step S17, 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.

FIG. 8 shows an external appearance of a panel of an operating device according to another embodiment of the present invention. The operation switch 31, the channel designation switch 34, and the LEDs 34, 35, 36 are the same as those shown in FIG. 33 is a setting switch and 37 is a setting switch.
LED, 38U is an upper channel selection switch, 39U is an LED corresponding to the upper channel selection switch 38U, 38L is a lower channel switch, 39L is an LED corresponding to the lower channel selection switch 38L. FIG. 8B is a detailed diagram of the channel designation switch 32. NP on key top
1 and NP2 indicate the upper channel and the lower channel, respectively, and the valid channels are displayed when the upper channel or the lower channel is selected by the changeover switches 38U and 38L. The lighting control system of the present embodiment should be designated. It is effective when used with a large number of channels. That is, when the upper channel is selected by the upper channel changeover switch 38U, there are a plurality of channel designation switches 32.
Functions as a switch that can specify the channel of NP1 shown on the upper side, while if the lower channel changeover switch 38L is pressed, it can specify the channel shown by NP2 of the channel specifying switch 32. Functions as a switch that can.

The allocation setting according to this embodiment is performed as follows. First, the setting switch 33 on the operation panel 3 is pressed to enter the allocation setting mode. This causes the LED 37 of the setting switch to light up. Operation switch 31 to assign the next channel
Select one and press. This causes the LED 34 of the operation switch to light up. Next, if the channel to be assigned is on the NP1 side of the channel designating switch, the channel designating switch 38U is depressed, and then the channel designating switch 32 is depressed. As a result, the LED 39U and the LED 36 corresponding to the channel designation switch 32 are turned on.
If it is on the side of the channel NP1 to be assigned, the channel designation switch 32 is continuously depressed to perform the assignment.

On the other hand, if the channel to be assigned is on the NP2 side of the channel designation switch, channel designation switch 3
Press 8L. This allows the channel specification switch 32
Will function as a switch corresponding to the channel shown on the NP2 side, and can be assigned by pressing the channel designation switch 32.

Repeat this to assign some channels. If there are more operation switches to be assigned, the operation switch 31
Repeat the operation from pressing. When all the allocation is completed, the setting switch 33 is pressed again to return from the allocation setting mode to the normal mode.

FIG. 9 is a flow chart showing the processing sequence of the central processing unit 1 in the embodiment of FIG. The operation when the allocation setting is performed in the above-described processing procedure will be described with reference to the flowchart of FIG.

First, when the power is turned on, the central processing unit 1 executes step S2.
Initialization is performed in 1, and monitoring data is received in step S22. In step S23, it is determined whether or not the setting flag is 1, and if it is not 1, it is determined in step S24 whether or not the setting switch signal is received. If the setting switch 33 is pressed, the process branches from step S24 to S25, and the setting flag is set to 1. Then, in step S26, the LED 37 of the setting switch 33 and the lower channel selection switch 38L
Set the transmission data to turn on the LED 39L of, and set the transmission data to turn off all the LEDs 34 and 35 of all the operation switches 31 and the LEDs 36 of all the channel designation switches 32, and set these data in step S27. Send. After that, the process returns to step S22.

Next, when the data indicating that the operation switch 31 is pressed is received in step S22, the setting flag is set to 1 in step S23.
Therefore, the process proceeds to step S28, where it is determined whether or not it is a setting switch signal. In this case, since it is not the setting switch signal, the process branches to step S29, and it is determined here whether it is the operation switch signal. Since the operation switch is pressed, the allocation flag of the operation switch is set in step S30, the transmission data indicating that the LED 34 corresponding to the operation switch 31 should be turned on is set, and these data are transmitted in step S27. And again step S22
Return to.

Next, when the data indicating that the channel designation switch 32, the upper channel changeover switch 38U or the lower channel changeover switch 38L is pressed is received in step S22, the process branches to step S31 through steps S22 → S23 → S28 → S29. In step S31, it is determined whether or not the allocation flag is set, and if it is not set, the step is
Return to S22.

If the allocation flag is set in step S31,
In step S32, it is determined whether or not the upper channel selection switch 38U has been pressed. If the upper channel selector switch 38U is pressed, the steps from step S32 to step
The process branches to S33, where the channel switching flag is set. Then, the transmission data to the effect that the LED 39U corresponding to the upper channel changeover switch 38U should be turned on is set, and the process proceeds to step S27.

If it is not the upper channel selection switch in step S32, it is determined in step S34 whether or not the lower channel selection switch is pressed. If the lower channel switch is pressed at step S34, the process branches to step S35 to reset the channel switch flag. Then, the transmission data indicating that the LED 39L corresponding to the lower channel changeover switch 38L should be turned on is set, and the process proceeds to step S27.

If it is not the lower channel selection switch in step S34, the channel switching flag is determined in step S36, and if the upper channel is designated, step S3
Go to step 7, if lower channel is specified
Each branch to 39.

In the case of the upper channel, it is determined whether or not the signal when the channel designation switch 32 is pressed is received in step S37. If the channel designation switch signal is received, the corresponding upper channel is assigned to the assignment memory of the corresponding operation switch 31 in step S38, and the transmission data indicating that the LED 36 corresponding to the corresponding channel designation switch should be turned on is transmitted. Set and proceed to step S27.

If the channel designation switch signal is not received in step S37, the process returns to step S22.

On the other hand, if it is the lower channel in step S36,
In step S39, it is determined whether or not the channel designation switch signal has been received. If the channel designation switch signal is received, the corresponding lower channel is assigned to the assignment memory of the corresponding operation switch in step S40, the LED display transmission data corresponding to the corresponding channel designation switch is set, and step S27 Go to. If the channel designation switch signal is not received in step S39, the process returns to step S22.

As described above, the pressing of the operation switch 31, the pressing of the upper channel switching switch 38U or the lower channel switching switch 38L, and the pressing of the channel designation switch 32 are appropriately repeated and allocated.

After that, when the setting switch 33 is pressed, the monitoring data is received in step S22, and the allocation is completed in step S41 via steps S23 and S28. Then, the display data of all the switches is set as the transmission data, the setting flag and the allocation flag are reset, and the process proceeds to step S27. The allocation is completed by transmitting these data in step S27.

In the normal mode, the monitoring data is received in step S22, and then the normal processing of step S42 is performed through steps S23 and S24. In this normal mode, as in the previous embodiment, the operation switch 31 functions with the corresponding wall switch 8 at two locations.

According to this embodiment, it is not necessary to provide the same number of channel designating switches 32 even if the number of connected channels is large. For example, assuming that the total number of connectable channels is 256, the number of channel designating switches 32 is only half, that is, 128. As a result, the operator panel is small and the cost is low.

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 whether the channel is assigned to any of the channels.
The 1: 1 correspondence makes the physical correspondence clear and improves the operability. Also, by using the channel specification switch by dividing it into upper and lower channels with the channel selection switch, it is not necessary to provide the same number of channel specification switches as the number of channels, and the number can be reduced to 1/2 or 1/3. be able to. As a result, the operating device becomes smaller and the cost can be reduced.
