[Industrial applications]

 The present invention relates to a lighting control system using a communication system using a transmission communication circuit, which collectively controls a large number of lighting loads set in a building and monitors the current status of the lighting load. Regarding

[0002]

[Prior Art]

 Conventional equipment includes a lighting control system that centrally controls a large number of lighting loads such as buildings and factories by a time-division multiplexing method using signal lines, and monitors and monitors the lighting condition. This is to divide a large number of lighting loads installed in a building into control units that are on / off controlled collectively, connect the lighting loads of each control unit to terminals, and connect these terminals with a common transmission line. This is an illumination control device that individually transmits address data and control data from the master unit by a time division multiplexing method to control on / off of a lighting load of an arbitrary control unit. In these devices, each terminal was assigned an individual address, and the master set the individual address of the terminal and the lighting load status. In this case, the individual address and lighting load status were set by providing a numeric key switch, a mode switch and a display on the master unit. In addition, in the wall base unit, an individual address switch and a dimming volume were provided for control.

[Problems to be solved by the device]

 In the above-mentioned conventional technique, when a plurality of lighting control devices and terminals are connected to the signal line, it is desired to control and monitor the plurality of terminals with a control signal from the lighting control device. In this case, in the conventional lighting control device, the address number of the terminal device is set by the ten-key switch and then the load state is set by the dimming switch. This method has a problem that it takes much time because the number of times the switch is pressed is large and complicated. In addition, in a switch box-mounted lighting control device, a dimming output is set for each address by pairing an address switch and a dimming volume. This method has a problem that the number of address switches and the dimming volume is increased, and dimming control of a plurality of terminals is not taken into consideration, resulting in an increase in size. An object of the present invention is to provide a miniaturized lighting control device capable of easily setting dimming output and displaying on a monitor.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, in the lighting control system of the present invention, a lighting control device connected to a signal line, a setting unit for setting an address of a cargo carrier, an operation unit for remotely instructing the terminal, and a lighting load for the terminal. A monitor display section, a lighting load setting section, an output setting section, and a display section are provided so that the monitor display changes each time the lighting load is selected, and the output display changes when the output setting section operates. ..

[0005]

[Action]

 Lighting switches can be turned on / off and dimming can be specified by the operation switch of the lighting control device, and status can be displayed on the monitor. The lighting control device sends a control signal to the terminal device according to the operation content of the operation switch, and the terminal device controls the output of the lighting load. For the dimming output setting, specify the dimming change with the setting switch, select the lighting load with the dimming switch and operation switch, and adjust the up switch and down switch according to the dimming level monitor display. Since the optical level is set, there is no malfunction.

【Example】

 An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a schematic diagram showing a configuration example of the present invention, in which a lighting control device 2 and a terminal device 3 are connected to a signal line 1. In addition, the lighting load 4 is connected to the terminal device 3 via the dimming light 5. The lighting control device 2 is operated by the power of the power line 7 branched from the distribution board 6, and the lighting power of the lighting load 4 is supplied. The lighting control device 2 controls the terminal device 3 by transmitting and receiving control signals via the signal line 1 in a time division transmission method. The terminal device 3 controls the lighting load 4 by setting a dimming level signal for the dimming light 5. FIG. 2 shows a front view of the lighting control device 2. In the lighting control device 2, in order to set an operation switch 8 for instructing remote operation of each terminal device 3, ON / OFF of the terminal device, monitor display lamps 9 and 10 for displaying a dimming state, and a dimming output. Setting switch 11 and setting indicator lamp 12 indicating the state of the setting switch, dimming switch 13 for selectively setting the lighting load 4 for dimming control, and dimming indicator lamp 14 and dimming indicating the status of the selected setting. It has an up switch 15 and a down switch 16 for setting the output up or down and a dimming level monitor indicator lamp 17 for indicating the dimming level. FIG. 3 shows a circuit block diagram of the lighting control device 2. A transmission / reception 20 is connected to the signal line 1 to transmit or receive a signal. The operation switch section 21 switches the state of the lighting load 4 to off, lighting, and dimming, and the state is displayed on the monitor display section 22. The setting switch section 23 is used to set the dimming level, and the setting indicator lamp 24 displays the setting state. The dimming switch 25 is combined with the operation switch section 21 to select the lighting load 4 and display the dimming setting state on the dimming indicator lamp 26. The dimming level is indicated on the dimming level monitor indicator lamp 27. indicate. The up switch 28 or the down switch 29 is a switch for adjusting the dimming level up or down. Next, the program of the microprocessor 39 will be described with reference to FIG. First, a process 41 of switching off, lighting, and dimming the illumination load 4 will be described. For example, when the operation indicator 8a is operated when the monitor indicator light 9a is on, the lamp 8a is off, and the lighting load 4 is off, the transmission circuit 31 transmits a control signal to the terminal 3a, and the lighting load 4 is turned on. 4 is turned on, the monitor display lamp 9a is turned off, and 8a is switched to turned on to display that the lighting load 4 is in a lighting state. When the operation switch 8a is operated again, the transmitter circuit transmits a preset dimming data signal to the terminal device 3a to dimm the illumination load 4, turn off the monitor indicator light 9a, and blink 8a. Switch to the dimming status display. Further, when the operation switch 8a is operated, an extinction data signal is transmitted from the transmission circuit 31, the illumination load 4 is extinguished via the terminal 3a, the monitor indicator lamp 9a is illuminated, and 8a is switched off to display the extinguished state. .. Next, the setting of dimming will be described. The dimming setting switch 11 is set to the operation 12 setting mode. At this time, the setting indicator lamp 12 is turned on. To select the illumination load 4, the dimming switch 13 is operated to turn on the dimming indicator lamps 14 and turn off all the monitor indicator lamps. The lighting load 4a is selected by the operation switch 8a, the monitor display lamp 9a is turned off, 8a is displayed in blinking, and the dimming level monitor display lamp 17 displays the dimming level. To increase the dimming level, operate the up switch 15 to display the dimming level monitor indicator lamp 17 up. To down the dimming level, operate the down switch 16 to adjust the dimming level monitor indicator lamp 17 Is displayed. The dimming level setting of another lighting load 4b is set by returning to the process 42 and operating the operation switch 8b to repeat this operation. When the setting switch 11 is operated after the setting of the dimming level, the monitor display shows the state of the lighting load 4 before the setting of the dimming level.
