The child terminal device 3-illumination load 4 and control lines 5 are multiple in <br/> Oh. The same applies to the operation switch section 8 and the monitor display section 9 on the master controller 2. By the way, the second operation switch unit 82 and the second monitor indicator light unit 92 are the second
It corresponds to the second child terminal 32. For example, the selection or switching of lighting, extinguishing, and dimming of the second lighting load 42 attached to the second slave terminal 32 is performed using the second operation switch unit 82. The second operation switch unit 82 is an address switch for designating the second child terminal 32 and the second lighting load 42, and also functions as a kind of flashing switch for switching its operation state. In the operation display mode, for example, the second monitor display lamp section 92 displays the operation state of the second illumination load 42.
The second monitor display lamp section 92 is composed of a display lamp 92a and a display lamp 92b. The indicator lights 92a and 92b are located near the second operation switch section 82. For example, when the second operation switch section 82 is pressed, the second illumination load 42 is turned on. Accordingly, the indicator lamp 92a belonging to the second monitor indicator lamp unit 92 is turned on, and the indicator lamp 92b is turned off. When the second operation switch unit 82 is pressed again, the second lighting load 42 is lit and lit. At the same time, the indicator light 92a blinks and the indicator light 92b turns off. When the second operation switch section 82 is further pressed,
The second illumination load 42 goes out. Accordingly, the indicator light 92a is turned off and the indicator light 92b is turned on. Thereafter, when the second operation switch section 82 is pressed, the state returns to the initial lighting state. FIG. 3 shows a circuit block diagram of the illumination control device 2. The transmission / reception 20 connected to the signal transmission path 1 transmits or receives a required signal. The control subject is a so-called microcomputer 39, which includes a microprocessor, a memory for storing a processing program for the microprocessor, and an input / output device connected to the operation switch unit 8 and the like. The processing program is shown in FIG.
It is something like Hereinafter, the processing block numbers in FIG. 4 will be described first, and the processing contents will be described following the colon (:). Processing block 101: A state switching process is performed by the operation switch. For example, each time the second operation switch unit 82 is pressed, the operation state of the second lighting load 42 attached to the second slave terminal 32 is advanced in the order of lighting, dimming, turning off, turning on, and so on. Address data and control data for that purpose are formed and transmitted from the transmission / reception 20.
Processing block 102: It is detected whether the setting switch 11 has been pressed. If the button is pressed, the process proceeds to a processing block 103. If the button is not pressed, the process jumps to a processing block 104. When it is necessary to adjust the dimming level set value for any of the lighting loads 4, the corresponding setting switch 11 is pressed, and the process proceeds to the processing block 103. Processing block 1
03: The setting indicator 12 near the setting switch 11 is turned on, and the process proceeds to the next step. Processing block 104: dimming switch 13
Detects if is pressed. If it is pressed, the process proceeds to processing block 105, and if it is not pressed, the process returns to processing block 101. Processing block 105: The dimming indicator lamp 14 near the dimming switch 13 is turned on. At the same time, all the monitor indicator lamps 9 are turned off. The display mode of each monitor display unit 9 departs from the operation display mode for displaying the distinction between lighting, extinguishing, and dimming. Processing block 106: It is detected whether the operation switch section 8 has been pressed. Depending on the result, proceed to processing block 107 or 108. Hereinafter, for convenience of explanation, it is assumed that the second operation switch unit 8 is pressed. Processing block 107: a second monitor indicator light portion 92 (only the indicator light 92a or 9) near the pressed second operation switch portion 8
2a and 92b) are turned on. The other first monitor display lamps 91 and the like keep the light-off state. As a result, the second operation switch unit 82 is displayed so as to be distinguished from others, and it is notified that the second operation switch unit 82 has entered the dimming level change mode. Processing block 10
8: It is detected whether the up switch 15 has been pressed. Processing block 109 or 110 depending on the result
Proceed to. Processing block 109: The display of the dimming level monitor display lamp 17 is increased. The dimming level monitor display lamp 17 has a bar graph display format, and indicates that the dimming degree has changed from 55% to 60%, for example. Processing block 110: detecting whether the down switch 16 has been pressed. The process proceeds to processing block 111 or 112 depending on the result. Processing block 11
1: The display of the light control level monitor display lamp 17 is reduced. Thus, for example, it is displayed that the dimming degree is changed from 55% to 50%. Processing block 112:
It detects whether the setting switch 11 has been pressed. If so, the process proceeds to processing block 106. If not, the process proceeds to processing block 113. The setting switch 11 at this stage is a memory rewrite confirmation switch. In the former case, the dimming level setting value for the second lighting load 42 attached to the second slave terminal 32 is set to, for example, 5
Rewrite from 5% to a new value, for example, 70%. Thereafter, the dimming of the second illumination load 42 is performed at the set value of 70%. Processing block 113: This processing is performed if the setting switch 11 is not pressed within a predetermined time. The display of the dimming level monitor display lamp 17 is returned to the original display of, for example, 55%, and a series of processing ends. In this case, the dimming level set value for the second lighting load 42 is, for example, 55% of the original.
Will be kept as is. Then, each monitor display unit 9 is returned to the normal operation display mode, and the control is returned to the processing block 101 at the beginning. Supplement the explanation. For example, the second operation switch unit 82 is like a blinking switch corresponding to the second lighting load 42. As a result, the operation state of the second lighting load 42 can be immediately switched in the order of lighting, dimming, turning off, lighting, and so on. In this case, there is no need for a person to input the address of the second lighting load 42. The result of the switching is indicated by the second monitor indicator light 9
2 is displayed. The second operation switch unit 82 is also used when adjusting the dimming level set value corresponding to the second operation switch unit 82. However, if the respective monitor display lamp units 92 remain in the normal operation display mode, it cannot be determined whether or not the second illumination load 42 has been selected. Therefore, in this case, each monitor display lamp unit 9 is turned off in advance, and only the second monitor display lamp unit 92 is turned on. In the present invention, the operation of the lighting, dimming, and off operations is switched by the operation switch unit 8, so that the operation is simple. Operation switch section 8
Since the monitor display unit 9 is used for switching the operation or displaying the result, and also for changing the dimming level set value, the number of these components is reduced.
