Description

[Detailed description of the invention] [Industrial application field].

The present invention relates to a lighting control system that centrally controls lighting devices using a main operation panel via a terminal device.

[Prior Art] FIG. 4 is a diagram showing the configuration of a conventional lighting control system as disclosed in, for example, Japanese Unexamined Patent Publication No. 59-60989.

In the figure, M is the main operation panel that performs overall control of the entire lighting control system, various settings such as lighting blinking and dimming, and signal transmission, and TL is the signal line for digital multiplex transmission. T1 has a unique address,
A terminal device for controlling blinking and dimming of a plurality of lighting devices LOI to LO4, Lll to L14 according to commands from the main operation panel M, Ts is remote information, and remote control switches S L, S
2 is a terminal device that transmits the status to the main operation panel M, and the main operation panel M determines whether it is received.

Control the corresponding lighting device.

In this way, the terminal T has input and output terminals, and is configured to be used for controlling lighting, checking switches, monitoring other things, and the like. Main operation panel M and terminals To, T2. As shown in the transmission signal diagram in Figure 5, the transmission signal between T3 consists of an address signal TA for each terminal device and a blinking/dimming control signal Tc for a plurality of lighting devices connected to this terminal device. This signal is sent to the corresponding terminal, and then the information from that terminal is transmitted to the main operation panel M by means of a return signal TB.
will be returned to. These series of transmission signals are communicated by multiplex transmission using a polling method, a cyclic time division method, or the like.

The conventional lighting control system is configured as described above, and the main operation panel M controls the lighting devices LOI to L14 of each terminal To and Tl.
When pattern control is performed all at once, it is performed as described above.

When a pattern control command is input to the main operation panel M,
The main operation panel M calls up the lighting control state corresponding to the lighting control pattern registered in advance from the internal memory, and transmits it to the terminal to which the lighting device to be controlled is connected according to the transmission signal format shown in Fig. 5. Do the following.

For example, the lighting control pattern (pattern 1) shown in Figure 6
Let us consider when to execute the following. First, if a command to execute, for example, pattern 1 is input on the main operation panel M, the main operation panel M will call up lighting control information corresponding to the control state of pattern 1 from the internal memory and perform a process as shown in FIG. Create a data table for lighting control. In this case, each lighting device is controlled in a two-bit manner, that is, when the bit is 11, the lighting device is turned on, and when the bit is 00, the lighting device is turned off.

When the control data table is created, the main operation panel M cyclically transmits data from the terminal TO at address O according to the format of the transmission signal diagram shown in Fig. 5 (in this case, TA=0000
0000. TC=11000000) transmission starts. Thereafter, the terminal device Tl of address 1, etc.
Transmission is performed as follows: terminal device T7 at address 7.

[Problems to be Solved by the Invention] In the conventional lighting control system as described above, transmission is controlled cyclically when performing pattern control, so it is difficult to control the lighting device of the terminal Tn with a large Atris n. If the time required to communicate with one terminal is t, it takes at least t·(n+1). Normally, this type of lighting control system cannot use very high transmission speeds due to malfunction countermeasures and cost constraints.
There is a problem in that the time of +1) becomes quite long and the responsiveness of the control of the lighting device to the operation input becomes poor.

The present invention was made to solve this problem, and an object of the present invention is to improve the responsiveness when controlling the pattern of lighting devices all at once.

[Means for Solving the Problems] The lighting control system according to the present invention has a simultaneous broadcast mode that allows simultaneous transmission to all terminals regardless of the address of each terminal, and provides each terminal with information in advance for simultaneous control. The contents of the control pattern are encoded and memorized, and during simultaneous pattern control,
In the main operation panel, a predetermined simultaneous broadcast mode signal different from any terminal device address signal common to each terminal device is sent as the above-mentioned address signal, and a predetermined simultaneous broadcast mode signal different from any terminal device address signal is received as the above-mentioned control signal in response to reception of a code signal according to the above-mentioned control pattern. Next, a pre-stored control pattern is read out from the transmitted code signal, and the connected lighting device is controlled accordingly.

[Function] In this invention, since the terminal devices store the contents of the control pattern in the form of a code in advance, during simultaneous pattern control, the code signal corresponding to the control pattern is sent from the main operation panel to all the terminal devices at the same time. By simply transmitting at the same time in information mode,
Each terminal device simultaneously controls each lighting device using a respective control pattern according to the code signal. Therefore, simultaneous pattern control with extremely good responsiveness is performed.

[Example] An example of the present invention will be described below with reference to the drawings. 1st
The figure is a configuration diagram showing one terminal device in one embodiment of the present invention.

In the figure, (1) is a receiver that takes in signals from the signal line TL, which converts the address signal TA of the transmission signal shown in Figure 5, and the control signal TC for blinking and dimming for each circuit into a DC pulse signal. . (2) is a transmitter that sends a signal to the transmission line TL, and transmits the status of the remote control switch, etc., to the main operation panel M as a return signal TB. (3) is an address setting unit consisting of a switch that sets a fixed address for the terminal device, and (4) receives a received signal, decodes it, determines the address, determines each control signal, and controls the lighting. The processing section is composed of a stored program type microcomputer that performs processing and creates output return signals, etc., and has a control output terminal (5) for the lighting device.

Before explaining the operation of this embodiment, the simultaneous broadcast mode signal of the lighting control system in this embodiment will be explained.

Here, we assume that the simultaneous broadcast mode signal is the simultaneous broadcast code 11.
It is defined as 111111. The simultaneous broadcast mode signal of this simultaneous broadcast code is the address signal TA in the transmission signal diagram of FIG.
When it is transmitted from the main operation panel M to the signal line TL, it is received and processed by terminals at any address in simultaneous broadcast mode.

Next, the operation of the terminal device of this embodiment will be explained with reference to the flowchart shown in FIG. Figure 2 shows this terminal processing unit (4)
3 is a flowchart showing an example of a control flow of FIG. When the terminal is powered on in step (6), the processing unit (4)
reads its own address from the address setting section (3) in step (7). Furthermore, in step (8), the main operation panel M
On the other hand, the pattern data transmission request data is sent to the main operation panel M via the transmitter (2) using the address signal TA and return signal TB shown in FIG. When the main operation panel M receives this pattern transmission request, it transmits to each terminal the pattern related to that terminal and the lighting control state at that time. The terminals receive the information for their own addresses, and in step (9) each terminal creates a pattern data table as shown in FIG. When these processes are completed, the processing unit (4) of the terminal enters the normal loop of receiving processing using its own address and reaching (10) where it performs processing based on the broadcast code. When the execution operation of pattern 1 is performed on the main operation panel M, the main operation panel M sends a simultaneous broadcast code to the TA of 11111111 (simultaneous broadcast code)T.
oooooooi (pattern data number) is input to C and sent onto the signal line TL. Each terminal device has a reception routine (
10), read the address signal section TA, and proceed to step (
11) decodes the simultaneous broadcast and enters the simultaneous broadcast mode,
Furthermore, the control signal TC is read and pattern number 1 is decoded in step (12). Next, in step (13), the pattern data table is referred to using this pattern number, and the pattern data (0100) is read and set.

This pattern data is used as the lighting control output at the output terminal (5
) to control the lighting device.

When this control is completed, the status is sent to the sending routine (16
) is sent back to the main operation panel M, and becomes ready for reception from the main operation panel M.

When the broadcast mode is not set, the address signal TA of the transmission signal sent from the main operation panel M is read in step (14), and if it is the own address, the process proceeds to step (15), whereupon the control is sent out. A control output is set according to the signal TC to control the lighting device.

Create a pattern table for each terminal in this way.

Since each terminal device simultaneously outputs the lighting control output of the pattern by simultaneous broadcasting, the time required for transmission control is constant, and a lighting control system can be configured in which the lighting device has good responsiveness to operations.

[Effect of the invention] As explained above, this invention provides a simultaneous broadcast mode,
By pre-coding and storing the contents of the control pattern for simultaneous control in the terminal devices, it is possible to perform pattern control on each terminal device at the same time, creating a lighting control system with extremely good lighting control responsiveness. There are benefits to be gained.
