DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a control state display method in a load control device that performs time division multiplex transmission via a transmission line to control a load.

BACKGROUND ART FIG. 5 is a front view of an operation input unit 1 of a light control device, which is a prior art load control device. This operation input section 1 is provided with eight switches S1 to S8, and green light emitting diodes G1 to G8 and red light emitting diodes R1 to R8 are provided in association with each of the switches S1 to S8. In order to set dimming data, the operation input section 1 also includes a mode changeover switch 2 and two light emitting diodes, one of which lights up in accordance with the switching mode of the mode changeover switch 2 when dimming data is input. 3 and 4, a display device 5 for displaying the amount of dimming control, etc., and a group of various key input switches 6 are provided.

In the operation input section 1 configured in this way,
When inputting light control data, the mode changeover switch 2 is operated to select either scene mode or individual light control data. The scene mode is a mode for setting the amount of dimming control for each scene. In other words, for example, by selecting switch S3, the setting for the third scene is performed, and in this state, operating switch group 6 , sets the dimming control amount in this scene. In addition, the individual dimming data refers to selecting the lighting load for each scene, that is, by selecting the switches S2, S4, and S6, in this case, selecting the switches S2, S4, and S6. The corresponding lighting load will be turned on.

When the switches S1 to S8 are operated in this manner, one of the green light emitting diodes G1 to G8 or the red light emitting diodes R1 to R8 is lit. That is, for example, when the switch S1 is selected, the red light emitting diode R1 is turned on and the green light emitting diode G1 is turned off. Further, when the switch S1 is cut off, the red light emitting diode R1 is turned off and the green light emitting diode G1 is turned on.

FIG. 6 is a flowchart showing the lighting control operation of the light emitting diodes G1 to G8 and R1 to R8 when dimming data is input. At step n1, it is determined whether the mode is scene mode or individual dimming mode from the switching state of mode selector switch 2, and if it is scene mode, the process moves to step n2.
It is determined whether a scene has been selected, that is, whether any one of the switches S1 to S8 is selected. For example, if switch S1 is selected, the process moves to step n3. , selected switch S1
Light up the red light emitting diode G1 corresponding to
The remaining switches S2 to S8 turn on the green light emitting diodes G2 to G8.

If no scene is selected at step n2, the process moves to step n4 and all switches S
Green light emitting diode G1~ corresponding to 1~S8
Turn on G8. In this way, only the switch corresponding to the selected scene lights up the red light emitting diode, and the switches corresponding to the remaining scenes light up the green light emitting diode.

If it is the individual dimming mode in step n1, the process moves to step n5, where it is determined whether the individual circuit is selected, that is, whether any one of the switches S1 to S8 is selected, and the selection is made. If so, in step n6, the red light emitting diode corresponding to the selected switch is lit, and the green light emitting diodes of the remaining switches are lit.

If no individual circuit is selected in step n5, the process moves to step n7 and all switches S
The green light emitting diodes corresponding to 1 to S8 are turned on. The red light emitting diode of only the switch corresponding to the selected individual circuit lights up, and the green light emitting diode of the switches corresponding to the remaining individual circuits lights up.

As mentioned above, regardless of the mode selected by the mode changeover switch 2 in the operation input section 1, the red light emitting diode of the selected switch S1 to S8 lights up and the switch is shut off. The green light emitting diode will light up for the switch that is present. Therefore, in the operation input section 1 using such a display method, when inputting dimming data, first the mode changeover switch 2 is turned on.
Switch to scene mode and press switches S1 to S8.
After setting the scene and the dimming control amount using the switch group 6 and the switch group 6, the mode selector switch 2 is switched to the individual dimming mode and the individual circuit to be dimmed is selected. There may be cases where the user forgets which scene is the currently selected scene.

An object of the present invention is to provide a control state display method for a load control device that can display the operating state in the operating mode of the load control device and improve the workability of inputting control information.

shall be. Generally, a signal having such a configuration is called a time division multiplexed signal.

The operation input section 11 and the operation sections 12 and 13 have unique address numbers, so when receiving a signal from the central processing section 19, it is necessary to check that the address signal F1 matches their own address number. The data signal F2 is read only in this case. Further, the signal source section 16 specifies the destination using the address signal F1.

Then, it is determined whether a scene has been selected, that is, whether any of the switches S11 to S18 has been selected. For example, if switch S11 is selected, the process moves to step m3, and the selection is made. Switch S1 that is
The red light emitting diode G11 corresponding to No. 1 is turned on, and the remaining switches S12 to S18 turn on the green light emitting diodes G12 to G18.

If no scene is selected in step m2, the process moves to step m4, and the green light emitting diodes G11 to G18 corresponding to all the switches S11 to S18 are turned on. As a result, the red light emitting diode of only the switch corresponding to the selected scene lights up, and the green light emitting diode of the switches corresponding to the remaining scenes lights up.

If the individual dimming mode is selected in step m1, the process moves to step m5, where it is determined whether a scene is selected, and if it is selected, the process proceeds to step m6.
Then, the green light emitting diode corresponding to the selected switch is turned on, and the green light emitting diode of the remaining switches and all the red light emitting diodes R1 to R8 are turned off. If no scene is selected in step m5, step
Move to m7, all light emitting diodes R1 to R8,
Turn off G1 to G8.

In step m8, it is determined whether an individual circuit is selected, and if so, the step
Move to step m9, keep the green light emitting diodes G1 to G8 in the state of steps m6 and m7 mentioned above,
Only the red light emitting diode corresponding to the currently selected switch is turned on, and the red light emitting diodes corresponding to the remaining switches are turned off. If no individual circuit is selected in step m8,
Move to step m9 and turn on the green light emitting diode G1.
~G8 remains in the state of steps m6 and m7 described above, and all red light emitting diodes R1~R
Turn off 8.

In this way, when entering scene mode,
When a scene is selected, the red LED is on and the green LED is off, and when no scene is selected, the green LED is on and the red LED is off. . Therefore, the selected scene can be clearly viewed. On the other hand, when inputting the individual dimming mode, the green light emitting diode corresponding to the currently selected scene is lit, so it is easy to tell which scene the currently selected scene is. This can be seen at a glance, and the workability of inputting dimming data can be dramatically improved.

Other colors may be used for the light emitting diodes.

Although the above-mentioned embodiment describes a light control device, the present invention can also be suitably implemented in a control device for controlling other loads.

Effects As described above, according to the present invention, in a certain operation mode among a plurality of operation modes, the operation display of the operation input switch in that operation mode can be displayed by combining the lighting states of a plurality of display elements. At the same time, since the operating state in the remaining operating modes is displayed, the workability of inputting control information can be dramatically improved.
