FIG. 6 shows detailed formats for each operation mode of transmission signals exchanged between the central processing unit (FIG. 2) and the terminal device (FIG. 3.4.5) as described above.

The lighting control system of this embodiment operates as a transmission system in three modes: normal mode, parent activation mode, and child activation mode. The normal mode is a mode in which the central processing unit 1 transmits a start signal and, if activated from a terminal, receives the terminal data signal.

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 central processing unit 1 in the lighting control system of this embodiment will be explained with reference to the flowchart in FIG.

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 setting flag is 1 or not. The setting flag is a flag that is set when the setting switch 32 of the operating device 30 is pressed to perform the setting process, and is reset when the setting process is completed, and indicates whether or not the allocation is in the setting mode. If the setting flag is not 1, the process branches to step S.4 and it is determined whether the received monitoring data is a setting start signal (setting switch pressed). If it is not a setting switch signal, step S
5, normal processing is performed. For example, when a predetermined turn on/off signal is sent by operating the wall switch 8, data to turn on/off the lighting load of the assigned channel can be sent to the server, or the assignment can be This process involves setting transmission data for turning on/off the lighting load of the channel in response to a channel number and a signal indicating lighting/unlighting being sent out by operating the controller 30. These days are step S
8, thereby turning on/off the lighting load of the corresponding channel.

On the other hand, if it is a setting start signal in step S4, it means that the setting switch 32 has been pressed to perform allocation, so a setting flag is set in step S6. Then, in step S7, transmission data indicating that all display LEDs corresponding to all operation switches should be turned off is set, and transmitted in step S8. This is a process of turning off the LED arranged on the operation switch (not shown) of the selector switch panel 3.

If the setting flag is 1 in step S3, it is determined in step S9 whether or not a setting completion signal has been received (the setting switch has been pressed). If not, step S1
0, it is determined whether or not a wall switch signal has been received, and if so, a flag is set for assignment of the corresponding wall switch (corresponding to an operation switch (not shown) on the selector switch panel) in step Sll. Then, in step SL2, transmission data indicating that the LED of the operation switch is to be turned on is set, and transmitted in step S8.

If it is determined in step SIO that it is not a wall switch signal, in step S13 it is determined whether the allocation flag is set, and if it is not set, the process returns to step S2. If the allocation flag is set, it is determined in step S14 whether or not a channel number has been received, and if so, in step S15, the corresponding wall switch is allocated to the corresponding channel in the memory. If no channel number has been received, the process returns to step S2.

If the setting completion signal is received in step S9, the allocation is ended in step 81B. Then, transmit data indicating the display status for all switches is set, the setting flag and the allocation flag are reset, and step S8
The transmission is performed in step S2, and the process returns to step S2.

Next, with reference to the flowchart of FIG. 8, the operation of the layout controller 30 in the lighting control system of this embodiment will be explained.

First, when the process starts, initialization is performed in step S1, and it is determined in step S2 whether or not the setting switch 32 is turned on. If the setting switch 32 is not on, the channel number input from the numeric keypad 34 is read in step S23, and the channel number is displayed on the display 31 in step S24.

Then, in step S25, it is determined whether the setting is in progress, that is, whether the layout is in the setting mode.

If it is not being set in step S25, step 32B
It is determined whether the on switch 35 or the off switch 36 has been pressed. If none of these switches have been pressed, the process returns to step S22, and if any of these switches have been pressed, the on/off monitoring data is sent to the central processing unit 1 in step S27, and the process returns to step S22.

If it is being set in step S25, step S28
It is determined whether or not the set key has been pressed, and if so, the channel number is transmitted in step S29, and if not, the process returns to step S22.

If the setting switch 32 is on in step S22, it is determined in step 330 whether or not setting is in progress. If the setting is not in progress, a setting in progress flag is set in step S31, a setting start signal is sent to the central processing unit 1, and the process returns to step S22.

If the settings are being made in step 330, step S32
The setting completion data is sent to the central processing unit 1, the setting flag is reset, and the process returns to step S22.

As described above, first, the assignment is performed by inputting the channel number using the operation device 30 and pressing the on switch 35 or the off switch 36, then step S22→S23 in FIG.
→S24→S25→S28→S27, the lighting/lights-off monitoring data of the channel is transmitted. This data is received by the central processing unit 1 in step S2 of FIG.
Through the process, the central processing unit 1 transmits the lighting/lighting-off data of the channel to the control terminal 5. As a result, the lighting load 6 of the designated channel is turned on/off, and the operator can confirm the correspondence between the channel number and the lighting load.

Next, it is assumed that the allocation is performed by pressing the setting switch 32 on the operating device 30. At this time, the allocation controller 30 enters the allocation setting mode through the processing of steps S22→S30→S31 in FIG. 8, and sends out a setting start signal. This signal is received by the central processing unit 1 in step S2 of FIG.
Subsequently, through the processing of steps S3→S4→S6→S7→S8, the central processing unit 1 also enters the layout setting mode.

Next, assume that the wall switch 8 to be assigned is pressed.

At this time, the wall switch 8 sends out a wall switch signal, and this signal is received by the central processing unit 1 in step S2 of FIG. Then, step S2→S3→S9→510→S
Through the process ll→S12→S8, a flag is set for the assignment of the wall switch 8.

Next, when assigning a channel number manually using the controller 30 and pressing the set switch 33, the data of the corresponding channel number is transmitted through the processing of steps S22 → S23 → S24 → S25 → S28 → S29 in FIG. Ru. This data is received by the central processing unit 1 in step S2 of FIG.
Through the processing of 0→313→S14→S15→S8, the central processing unit 1 allocates the channel.

Finally, after repeating the above process as appropriate, it is assumed that the setting switch 32 is pressed again using the operating device 30 for allocation. At this time, the allocation is as follows: Steps S22→530→S3 in FIG.
By the process 2, the allocation cancels the setting mode and sends a setting completion signal. This signal is received by the central processing unit 1 in step S2 of FIG. 7, followed by steps S3→S9.
→By the process of Sle, the central processing unit 1 is also released from the allocation setting mode.

As described above, the allocation is completed.

[Effects of the Invention] As explained above, according to the present invention, the assignment for assigning the wall switch and the control circuit system (lighting load) of the control terminal device is provided with an operating device and can be operated on site. Since the layout is done by doing this, the operation is easy to understand and operate. In particular, since the correspondence between channel numbers and lighting loads can be confirmed on site, this is convenient when installing new lighting equipment or changing the layout of lighting patterns in existing lighting equipment. Furthermore, since the assignment can be performed on-site, only one operator is required.
