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 a start signal is transmitted from the central processing unit 1, and if there is an activation from a terminal, processing such as receiving the terminal data signal is performed. 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, to turn on or off the lighting load 6). The monitoring mode is a mode used to monitor the load status of each terminal, such as monitoring the status of the wall switch 8, for example. The child activation mode is a mode in which processing for starting the central processing unit 1 from each terminal device side is performed. 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 this embodiment will be described with reference to the flowchart in FIG. 7 and FIGS. 1 to 6.

First, when the power is turned on, the central processing unit 1 performs step S1.
Initialization is performed in step S2, and monitoring data is received in step S2.

Note that the signal transmission in this embodiment is time division multiplexed transmission, and transmission and reception are performed in synchronization with 50 or 60 power supply cycles. The monitoring data reception in step S2 is a process in which switch operation data in the terminal device is transmitted to the central processing unit in the slave activation mode and is received.

Next, in step S3, it is determined whether the data is the press data of the normal mode switch. If the received monitoring data is not normal mode switch press data, it is determined in step S4 whether or not it is a first mode switch signal. 1st
If it is a mode switch signal, it means that the first mode switch 388 has been pressed to perform allocation, so the first flag is set in step S5. Then, transmit data is set to turn on the LED 36L of the first mode switch 36S, and furthermore, the all-operation switch 3
Transmission data indicating that all of the display LEDs 34 and 35 corresponding to number 1 should be turned off is set and transmitted in step S6.

As a result, the L E D of the first mode switch 36S
36L lights up, and all other LEDs 34.35°37L go out.

Next, the process returns from step S6 to step S2 to receive the monitoring data again. If the operation switch 31 is pressed here, the sequence is steps S2→S3→S4→S.
7→S8→S9→SIO→Sll and step S12
leading to. Since the first flag is set to 1 in step S12, the process branches to step 813, where transmission data indicating that the LED 34 of the corresponding operation switch 31 is turned on is set, a memory storage location is designated, and step S6 is performed. Send.

Next, the process returns to step S2 again to receive monitoring data.

If the second mode switch 37S is pressed here, the sequence progresses from step S2→S3→S4→S7 and branches from step S7 to Si2. Here, since the first flag is set to 1, the process branches from step S14 to step S15, where the second flag is set and the second flag is set to 1.
Transmission data to turn on the LED 37L of the mode switch 378 is set and transmitted in step S6. As a result, LED I7L of the second mode switch 378 lights up.

Next, the process returns from step S6 to step S2 to receive the monitoring data again. If the operation switch 31 is pressed here, the sequence is steps S2-83→S4→S.
7→S8→S9 and reaches step SIO. Since the second flag is set to 1 in step 81G, the process branches to step 81B and the L of the corresponding operation switch 3L is set.
Set the transmission data to turn on the ED35, store and allocate the data of the specified channel (selected from a group of predetermined channels that can be specified in the second mode) in the corresponding memory storage location. .

Then, it is transmitted in step S6.

Next, the process returns to step S2 again to receive monitoring data.

If the third mode switch 389 is pressed here, the sequence is steps S2 → S3 → S4 → S7 → S8
The process branches from step S8 to step S17. Here, since the first flag is set to 1, step S17
The process branches to step 31g, sets the third flag, sets transmission data to turn on LEDa8L of the third mode switch 888, and transmits in step S6.

This allows ′! J3 mode switch 388 L E
D 38L lights up.

Next, the process returns from step S6 to step S2 to receive the monitoring data again. If the operation switch 31 is pressed here, the sequence is steps S2→S3→S4→S.
7→S8→S9→SIO and reaches step Sll. Since the third flag is set to 1 in step Sll, the process branches to step S19, where transmission data indicating that the LED 35 of the corresponding operation switch 31 is turned on is set, and the specified channel is set in the corresponding memory storage location. Data (selected from a group of predetermined channels that can be specified in the third mode) is stored and allocated. Then, it is transmitted in step S6.

Next, the process returns to step S2 again to receive monitoring data.

If the normal mode switch 33 is pressed here,
The sequence branches from step S3 to 820. Then, all switch display data is set, the first, second, and third flags are reset and transmitted in step S6. This completes the allocation.

As mentioned above, steps S2 → S3 → S4 → S5 → S6
As a result of the processing, the allocation is set to the first mode of the setting mode, and steps S2→S3→S4→S7→S8→S9→S10→5
A wall switch to be assigned is selected by processing 11-312→S13→S6. Then, step S2→S3→
The second mode is set by the process of S4→S7→S14→S15→S6, and step S2→S3→S4→S7→S8→S
A channel from the first group is assigned to the wall switch through the processing of 9→SIO→S16→S6. Furthermore, steps S2→S3→S4→S7→S8→S17→
The third mode is set by the processing of S18→S6, and step S
2→S3→S4→S7→S8→S9→SIO→Sll→
Through the process from S19 to S6, a channel from the second group is assigned to the wall switch.

After repeating this process and performing several assignments, the normal mode switch 33 is pressed to complete the assignment.

Note that when the assignment is not processed, that is, when the first, second, and third flags are all 0, the operation switch 31 of the controller 3 is used as a switch to turn on/off the channel that has been assigned in advance. be able to.

Also, in normal times, normal processing is performed in step S21 to monitor the operating state of the wall switch 8 and send control data to the corresponding control terminal.

When the wall switch 8 is pressed after the assignment has been made as described above, the monitoring data is transferred from step S2 to step S3.
→S4 →S7-58-S9 →SLQ 4S11-4
The process proceeds to step S21 via S12. Step S21
Then, the central processing unit 1 reads the assignment data corresponding to the wall switch 8 from the assignment data stored in the memory 11, and turns on the corresponding channel according to the assignment. As a result, the lighting loads 6 of the channels assigned in advance are lit.

[Effects of the Invention] As explained above, according to the present invention, an operating device for allocating a wall switch and a control circuit system (lighting load) of a control terminal device is provided, and the allocation can be performed by operating the operating device. The operation is easy to understand and operate. Also, if you install an indicator light that corresponds to the switch,
It is also easy to check which channel it is assigned to.

Furthermore, since the functions of the operation switch are switched between the first mode, second mode, and third mode, the number of switches can be reduced, the operation device can be made smaller, and costs can be reduced. In particular, since the above-mentioned allocation is considered to be operated only once or twice a year, a lighting control system with high operability, small size, and low cost, such as the lighting control system according to the present invention, is effective.
