Description of the Related Art A lighting control system that can control dimming of a lighting load in steps is known. In such a dimming control system, each time the "up" switch or "down" switch of the UDS switch is operated, the operation signal is sent to the main operation panel via the transmission line, and the main operation is performed. The panel is configured to transmit grayscale data to the dimming control terminal to which the circuit assigned to the UDS switch belongs, using a one-step dimming time and a one-step grayscale data change amount that are fixed in advance in the system. was.

(Problem to be solved by the invention) However, each time the "up" switch or "down" switch is operated, the operation signal is sent to the dimming control terminal via the above transmission line. There is a problem in that the transmission line tends to become busy, and the responsiveness of the system to other switch operations deteriorates.

The present invention has been made in view of the above points, and its purpose is to create gradation data for UDS switch operations using a dimming control terminal instead of using the main operation panel.
An object of the present invention is to provide a lighting control system that can avoid a busy state of a transmission line caused by the operation of a UDS switch and improve the responsiveness of the system to other switch operations.

[Structure of the Invention] (Means for Solving the Problems) At least a dimming control terminal and a dimmer switch are connected to the main operation panel via a transmission line, and when the dimmer switch is operated, the dimmer control terminal is connected to the main operation panel via a transmission line. In a lighting control system that can step-wise control the dimming of a lighting load connected to a circuit under terminal control, the main operation panel receives switch operation information transmitted from the dimmer switch and performs switch operation. A transmitter is provided for transmitting information to a dimming control terminal belonging to a circuit assigned to the dimmer switch, and the dimming control terminal creates dimming data by referring to the switch operation information. This is a lighting control system characterized by comprising gradation data creation means.

(Function) When the main operation panel receives the switch operation information of the dimmer switch, it transmits the switch operation information to the dimmer control terminal belonging to the circuit assigned to the dimmer switch, and receives this switch information. The dimming control terminal device creates gradation data by referring to the switch information, and controls the dimming of the lighting load connected to the dimming control terminal device.

(Example) An example of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of the lighting control system. In FIG. 1, numeral 11 is a main operation panel that controls the system in an integrated manner. This main operation panel 11 has a built-in microcomputer and its peripheral circuits.

This main operation panel 11 has an LCD that displays various display data.

The assignment performed in response to the operation or the specification by OCR receives the switch operation information transmitted from the assignment control means and dimmer switch that performs the processing, and assigns the switch operation information to the circuit assigned to the dimmer switch. A transmitting means for transmitting data to the dimming control terminal device is provided.

The main operation panel 11 is connected to dimming control terminals 131 to 13 through two transmission signal lines 12. , UDS switch 14,
A light sensor terminal 15 and the like are connected. An optical sensor 16 is also connected to the sensor terminal 15 . Furthermore, although not shown in the transmission signal line 12, an 0N-O
FF terminal, individual switch, and other UDS switches are connected.

Four circuits are connected to each of the dimming control terminals 131 to 13, and a lighting load is connected to each circuit.

From the main operation panel 11 to the dimming control terminals 13, -1
Signal transmission to 3° is performed in voltage mode, and signal transmission from the dimming control terminals 13+ to 13° to the main operation panel 11 is performed in current mode.

Next, a plan view of the UDS switch 14 is shown in FIG. This UDS switch 14 includes an up switch 141 that is operated to brighten the lighting, a stop switch 142 that is operated to stop the previous switch operation, a down switch 143 that is operated to dim the lighting, and a down switch 143 that is operated to turn on/off the lighting. On/off switch 14 operated to turn off the light
4 are provided. This UDS switch 14 transmits data including switch operation information for identifying whether the switches 141 to 144 are operated to the main operation panel 11 in a data format shown in FIG. 4.

In addition, the lighting control terminals 131 to 13. In the memory, an area for storing the data shown in FIG. 3 is secured for each UDS switch. That is, this memory contains the current gradation data (0 to 31), the up FG (flag) which is set to "1" when the up switch 141 is operated, and
When the down switch 143 is operated, the down FG (flag) is set to "1", when the stop switch 142 is operated, the stop FG (flag) is set to "1", and the on/off switch 144 is operated. It is inverted each time it is set, and when it is set to "1", lighting processing is performed, and when it is reset, lighting processing is performed.

The memory of the main operation panel 11 also includes a key operation section 11b.
The designated layout data is stored by operating the button or by reading the layout card with the 0CR11c.

Here, the allocation data is data relating which UDS switch controls the lighting load connected to which circuit (1 to 4 circuits) of which dimming control terminal device.

Next, the operation of an embodiment of the present invention configured as described above will be explained. First, we will briefly explain the process of allocating the connection relationships of the four circuits connected to the UDS switch and the dimming control terminal, which is performed before actually using this lighting control system. This assignment is processed using the key operation section 11b or the assignment card shown in FIG.
This can be done by reading it with R11c.

For example, when the assignment process is performed by key operation, display the assignment menu (Fig. 6) for each UDS switch on the LCD 11a by operating a predetermined key, and then move the cursor by operating the cursor switch of the key operation section 11b. is moved to a predetermined position to specify which circuit of which dimming control terminal device the switch should be connected to. In other words, by displaying the menu shown in Fig. 6 on the LCD 11a, moving the cursor to a predetermined position, and inputting a circle mark, the assignment of the switch and the circuit under the control of the dimming control terminal is processed. It will be done.

As a result of the above layout processing, the layout table shown in FIG. 7 is stored as layout data in a predetermined area of the memory in the main operation panel 11. In this assignment, the switches are assigned to the circuits (1 to 4) of the dimming control terminal device through processing. For example, the allocation table in FIG. 7 means that switch A is connected to any of dimming control terminals 1 to 4 of dimming control terminal a.

Furthermore, the above processing is performed when the allocation is performed by operating the key operation unit 11, but to specify which circuit of which terminal device, mark the predetermined value on the allocation card shown in Fig. 8. It can also be set by This allocation card is 0CR
11c, the table shown in FIG. 7 is stored as layout data in a predetermined area of the memory of the main operation panel 11.

Next, processing when the UDS switch 14 is operated will be explained. First, when the user operates the UDS switch 14, data having the format shown in FIG. 4 is transmitted from the UDS switch 14 to the main operation panel 11 via the transmission signal line 12. When the main operation panel 11 receives this data, it refers to the table for the layout shown in FIG. 7, and selects the dimming control terminal 13 to which the data having the transmission format (including circuit designation identification data) shown in FIG. 5 is allocated. The dimming control terminals 13□ to 137 that have received the data having the transmission format shown in FIG. 5 perform the processing shown in FIG. 9.

First, the dimming control terminals 13, -13. In step 511), it is determined whether the transmission data has been received, and if it is determined that the on/off switch 144 has been operated "on", the "on JFG" in the memory is set. (Step 512).Then, the current gradation data stored in the memory of the dimming control terminal device 13, - 13 is output to the load, and the dimming level specified in the gradation data is output. The load is turned on (step 514).

On the other hand, if it is determined in step 512 that the "OFF" operation has been performed, the input JFG is reset and the UP FG, DOWN FG, and STOP FC stored in the memory are reset.
are all reset (step S15, 516).
. Then, the load is turned off (step 517).

If it is determined that the up switch 141 or the down switch 143 has been operated, only the up FG of the memory is set (“1”) or the down FC is set (“1”).
is set (“1”) and other FGs are reset (
Steps S18-521). Then, the above step S2
0 or after the process of S21 is executed, the dimming time (1 second) is set in the subtraction timer of the memory (step 5
22).

On the other hand, if it is determined that the stop switch 142 has been operated, all of the UP FG, DOWN FG, and STOP FC of the memory are reset (to "0") (steps 823, 524).

As described above, processing based on the switch operation information transmitted from the UDS switch 14 is performed by the dimming control terminal 1.
3. ~1B, will be held.

Next, with reference to FIG. 10, the dimming control terminals 131 to 1
The process of creating gradation data performed at 3° will be explained. First, the main operation panel 11 determines whether "JFG" is set in the memory and determines whether it is set (step 531).

If it is determined in step S31 that the illumination is set, that is, if the user has specified that the illumination should be turned on, it is determined whether the up mode FG is set (step 532). If the determination in step S32 is rYESJ, it is determined whether the current gradation data stored in the memory is "31" (
Step 833).

If rYEsJ is determined in step 333, since there is no gradation whose gradation data is greater than "31", FG is set during memory up, and FG is set during stop (step 534). ).

On the other hand, if the determination in step 533 is rNOJ, it is determined whether the value of the subtraction timer is rOJ (step 535). Here, as described above, each time the up switch 141 or the down switch 143 is operated, the dimming time (1 second) is set in the subtraction timer (step 522 in FIG. 9). The value of this subtraction timer is changed to 0.0 by the 0.1 sec interrupt shown in FIG. It is subtracted by l5ee.

If the determination in step S35 is rYESJ, the current gradation data stored in the memory is +1.
The current gradation data is stored as current gradation data, and the current gradation data is updated (step 536).

The updated gradation data is then output to the load (step 537). Then, the electronic ballast controls the dimming of the load at a brightness corresponding to the gradation data. and,
The dimming time is set in the subtraction timer (step 538
). Thereafter, while the up FC is set, step 531. S32. S33. The process of S35 is repeatedly executed. Then, the dimming time T has elapsed,
When the value of the subtraction timer reaches rOJ, r
If YESJ is determined, the current gradation data stored in the memory is incremented by 1 and stored as current gradation data, and the current gradation data is updated (step 536
). Then, the updated gradation data is output to the load (
step 537). In this way, while the FG is set during up, LV adjustment data that increases by 1 every second is output to the load to perform dimming control.

Then, as time passes, the gradation data output from the dimming control terminal increases and reaches "31", and it is determined to be rYEsJ in the determination at step 533, and the FG during uploading.
is reset, no more gradation data will be output.

On the other hand, if it is determined in step S32 that it is rNOJ, it is determined whether the down FG is set. If the determination in step S39 is rYESJ, the current gradation data stored in the memory is "1".
It is determined whether (step 540).

If rYEsJ is determined in step S40, the down FG of the memory is reset and the stop FG is set (step 541).

On the other hand, if the determination in step S40 is rNOJ, it is determined whether the value of the subtraction timer is "0" (step 542). Here, as described above, each time the up switch 141 or the down switch 143 is operated, the dimming time is set in the subtraction timer (9th
Step 522 in the figure). The value of this subtraction timer is changed to 0.1 by the 0.1 sec interrupt shown in FIG.
see is subtracted.

If the determination in step S42 is "YES", then -
1 and stored as current gradation data, and the current gradation data is updated (step 843).

Then, the updated gradation data is output to the load (step 544). Then, the dimming time is set in the subtraction timer (step 545). Thereafter, while the up FC is set, the dimming time set in step S45 becomes "0" until step S31. S32.
The processes of S39, 540° and S42 are repeatedly executed.

Then, when the dimming time has elapsed and the value of the subtraction timer becomes "0", it is determined to be rYEsJ in step S42, and the current gradation data stored in the memory is subtracted by 1 and set as the current gradation data. The data is stored, and the current gradation data is updated (step 543).

Then, the updated gradation data is output to the load (step 544). In this way, while the down FG is set, gradation data that decreases by 1 every second is output to the load.

Then, when the gradation data output to the dimming control terminal decreases with the passage of time and reaches "1", step S
40 is determined to be rYESJ, and the FG is reset during down, so that gradation data lower than that will not be output.

As described above, when the up switch 141 or the down switch 143 is operated, the main operation panel 11 receives the switch operation information and outputs the switch operation information to the dimming control terminal assigned to the switch. , the gradation data is created using a dimming control terminal.

[Effects of the Invention] As detailed above, according to the present invention, gradation data for UDS switch operations is created using a dimming control terminal instead of using the main operation panel. It is possible to provide a lighting control device that can avoid the busy state of the transmission line caused by the above and improve the responsiveness of the system to other switch operations.
