Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a lighting control system that centrally controls blinking and dimming of a plurality of lighting equipment, and in particular, the present invention relates to an improvement of a lighting control system that centrally controls blinking and dimming of a plurality of lighting equipment, and in particular, a terminal device that controls blinking and dimming control terminal switching. A switch is installed to transmit the status to the main operation panel when the system starts up.

[Conventional technology]

FIG. 5 is a diagram showing the configuration of a conventional lighting control system shown in, for example, the specification of Japanese Utility Model Application No. 189912/1980, in which 1 is a main operation panel, 2 is a communication line, and 3 is a blinking control system. A terminal device 4 is a dimming control terminal device, and a plurality of blinking lighting devices 58 to 5d are connected to the blinking control terminal N3. Similarly, a plurality of dimming lighting devices 6a and 6c are connected to the dimming control terminal 4.

A blinking lighting bag [5a to 5d, blinking control and dimming lighting device 6a] is connected to the blinking control terminal 3 and the dimming control terminal 4 from the main operation panel 1 through the communication line 2.

The control signal for controlling the dimming of the light control unit 6b and the return signal sent from these signals back to the main operation panel are received by multiplex transmission such as a polling method or a cyclic time division method.

In this type of lighting control system, in order to control the dimming of a lighting device, for example, as shown in Japanese Patent Laid-Open No. 55-163796, 2-bit illumination flilJ sister outputs are combined to perform dimming control. This method is usually used.

Since it is necessary to give a 2-bit control signal to one dimming lighting circuit, in conventional lighting control systems, as an example, when controlling dimming using the outputs of circuits 1 and 2, As shown in Table 1 below, you can perform dimming ftIJ by combining the operations of circuit 1 and circuit 2, or fix the address that can be connected to the dimming control terminal in advance, and then For circuit operations with circuit numbers determined as shown in Table 2 of
It outputs the control output of P1- and performs dimming control.

Table 1 Table 2 Conventional lighting control systems are configured as described above, so if the former method is adopted, the dimming control method is unnatural and has poor operability. In addition, the latter method has problems such as difficulty in dealing with increases and decreases in the number of dimming terminals.

[Problem that the invention seeks to solve]

In order to solve these problems, the inventor first configured the lighting control system so that the address of each number of terminals for dimming 2 blinks can be set using a dimming terminal assignment input device,
The operability is improved by making the dimming control wholesale command easier, and the settings of this dimming terminal assignment input device can be changed in response to an increase or decrease in the number of dimming/blinking circuits in the system. We have proposed a lighting control system that can handle this.

In the lighting control system proposed earlier, although variable, the possible addresses of the blinking terminal and dimming terminal are fixed. For example, in one room, there is a lighting device for dimming and a dimming device for blinking. If these devices coexist, there may be a lack of continuity in terminal device addresses and circuit numbers in one room, which poses problems in terms of system management and circuit operation.

This invention was made to solve this problem, and even when a dimming lighting device and a flashing lighting device coexist in one room, it provides continuity to the circuit numbers within the room. An object of the present invention is to obtain a lighting control system that can improve operability in system management or circuit operation.

[Means for solving problems]

In the lighting control system according to the present invention, a terminal device of the lighting control system is provided with a changeover switch for switching between a blinking control terminal device and a dimming control terminal device.

[For production]

In this invention, by transmitting the state of the changeover switch to the main operation panel, the configuration of the blinking control terminal device and the dimming control terminal device is grasped on the main operation panel, and the dimming control terminal device 2 blinks. Randomly choose the address to which each control terminal is connected.

〔Example〕

Embodiments of the lighting control system of the present invention will be described below based on the drawings. FIG. 1 is a diagram showing the hardware of a terminal device in one embodiment, and FIG. 2 is a flow chart of the software of the terminal device in this invention.

First, in FIG. 1, the same parts as those in FIG. 5 will be described with the same reference numerals. This FIG. 1 shows the terminal devices of the blinking control terminal device 3 and the dimming control terminal device 4 in FIG. 5.

In this FIG. 1, a receiving section 7 is connected to the communication line 2, and the receiving section 7 receives the transmission data from the main operation panel 1 shown in FIG. The signal is converted into a pulse signal and transferred to the input terminal (1) of the processing section 9.

Further, the output terminal OS of the processing section 9 is connected to the communication line 2 via the transmitting section 8 . If the terminal device shown in FIG. 1 is the blinking control terminal device shown in FIG. 5, the transmitter 8 uses the control signal from the dimming control terminal device shown in FIG. It is designed to be transmitted to the main controller via line 2.

Conversely, if the terminal device shown in FIG. 1 is the dimming control terminal device shown in FIG. 5, the transmitter 8 uses the control signal from the blinking control terminal device shown in FIG. The information is transmitted to the main operation panel via the communication line 2.

Further, reference numeral 10 denotes an address setting section, which sets the unique addresses of the blinking control terminal 3 and the dimming control terminal 4 and outputs them to the input terminals 12 to I6 of the processing section 9.

Reference numeral 11 denotes a changeover switch, which is one of the features of this invention. This changeover switch 11 is for switching between the blinking control terminal 3 and the dimming control terminal.
Input terminal I7 of processing unit 9. I.

It is connected to the.

The processing unit 9 receives the signal from the receiving unit 7 through the input terminal IX, decodes it, determines the address, determines each control signal, processes for lighting control, creates a return signal, etc. It is composed of a microcomputer and has output terminals 04-06. Of these output terminals O1-05, output terminals 01-04 are output terminals corresponding to control signals for blinking and dimming each circuit, and output terminal OS is an output terminal for data sent to the main operation panel.

Next, the operation of the present invention will be explained using the flowchart of FIG. 2. The explanation based on this example is as follows.
A menu drive type lighting control system as described in Japanese Utility Model Application No. 189912/1982 will be described.

Before turning on the power to the blinking control terminal and dimming control terminal, the address and the blinking control terminal and dimming control terminal must be set as initial settings for the blinking control terminal and dimming control terminal. Depending on whether the output terminal of the light control terminal is used for dimming control or blinking control, a changeover switch 11 for switching the dimming control terminal 1 and blinking control terminal is preset.

Next, when the blinking control terminal device and the dimming control terminal device are powered on and reset, the processing section 9 starts the control operation according to the flowchart of FIG. 2.

After completing initialization such as stack and input/output settings (step S1), the processing section 9 scans the input terminals 12 to 6 and takes in the data of the address setting section 10 as its own address (step S2).

Next, the processing section 9 receives the input terminal 17. I6 is scanned to read the state of the changeover switch 11 of the dimming control terminal word 1 blinking control terminal fold (step S3).

This selector switch 11 selects the dimming control terminal when the input terminal 7 is rLJ and the input terminal 6 is rHJ.
When the input terminal I7 is "H" and the input terminal I6 is rLJ, the blinking control terminal is selected. Changeover switch 1 in Figure 1
Setting state 1 indicates a state in which a dimming control terminal is selected.

After that, the processing section 9 rearranges the addresses and the contents of the changeover switch 11 according to the main operation panel and communication control protocol, and then sends the data from the output terminal 06 of the processing section 5 to the transmission section 8. 8 to the main operation panel via the communication line 2 (step S4), and normal processing is performed in the following step S.

The main operation panel stores the addresses of these blinking control terminals, dimming control terminals, and settings for dimming 2 blinking control as a table, and when a circuit number is input, this table is referenced. The circuit number connected to the terminal set as a terminal for dimming/pressing control has the display number 2 connected to the terminal set as a terminal for controlling display 2 as shown in Figure 3. The control shown in FIG. 4 is performed on the circuit number.

To perform dimming control, in Figure 3, by pressing the shift keys for "Chocolate 1" and "Chocolate 2", the data (0, 1) for "Chocolate 1" will be automatically set. For ``Created 1'' and ``Chiyukou 2'',
(1,0)2 data is automatically created and sent to the corresponding terminal to perform dimming control.

〔Effect of the invention〕

As explained above, the present invention includes setting a changeover switch for switching between a terminal word for flashing control and a terminal for dimming control in a terminal device, and transmitting the state of this changeover switch to the main operation panel. Since the configuration of the flashing control terminal and the GGI light dimming control terminal can be checked on the main operation panel, the address to which the dimming control terminal 2 is connected. can be taken at random, and therefore, even if a dimming lighting device and a flashing lighting device coexist in one room, it is possible to provide continuity to the circuit numbers within the room.

Accordingly, it is possible to improve the operability in system management or circuit operation.
