FIG. 5 is a communication sequence diagram showing a communication operation in the lighting control system of FIG.

 Next, the operation will be described.

The lighting equipment (4j) (4k) (4l) (4m) and the floor controller (2b) connected to the transmission line (6c) in the floor of the floor controller (2c) under the control of the lighting control system master unit (1) The control content for collectively controlling the lighting devices (4g) and (4h) connected to the in-floor transmission line (6b) is pattern 1. In this case, first, an operation request command for pattern 1 is input from the lighting system master (1).

The lighting control system master unit (1) sends a selection signal of pattern 1 as a control signal on the transmission line between floor controllers (5) according to a certain communication protocol.

The floor controller (2c) detects its own address from among the control signals on the inter-floor controller transmission line (5) and receives this control signal. Further, the control signal is interpreted to be a selection signal of pattern 1 based on the content of the control signal.
The signal is converted into a control signal on the transmission line (6c) in the floor controller and transmitted on the transmission line (6c) in the floor controller.

The load control terminal (3g) receives this control signal and turns on the lighting devices (4j) and (4k) according to the content of the command.

Next, the front controller (2) similarly transmits a control signal (9) to the load control terminal (3h), and thereby turns on the lighting devices (4l) and (4m).

Further, the lighting control system master unit (1) similarly sends a selection signal of pattern 1 to the floor controller (2b), and the floor controller (2b) transmits the selection signal to the load control terminal (3).
By similarly controlling d) and (3e), each lighting device is controlled to a state of a predetermined pattern via the load control terminal.

[Problem to be Solved by the Invention] Since the conventional lighting control system is configured as described above, the number of control content patterns increases according to the number of provided lighting devices, and a control signal transmitted from the central control device. The number of control patterns indicated by becomes enormous, the load on the floor controller that needs to store the control pattern increases, and the connected load control terminals are not all control targets. Even if the load control terminal is changed, there is a problem that a control signal is transmitted from the central control unit to a floor controller in which all the connected load control terminals do not change the state, thereby performing a useless operation.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems as described above, and an object of the present invention is to provide a lighting control system capable of performing a collective control from a central control device without a large burden on each device.

[Means for Solving the Problems] The lighting control system according to the present invention comprises a storage means for storing a floor pattern indicating a combination of control contents when collectively controlling a load control terminal connected to each floor controller. Transmission means provided in the controller, for individually setting a floor pattern of each floor controller from each operation request input to the central control device, and transmitting a control signal corresponding to the floor pattern to the corresponding floor controller. It is provided in the central control unit.

[Operation] In the lighting control system according to the present invention, the floor pattern of each floor controller corresponding to the operation request is individually set by the transmission means of the central control device and transmitted as a control signal to the corresponding floor controller. Since each floor controller performs control with a floor pattern corresponding to the transmitted control signal among the patterns stored in the respective storage means,
In each floor controller, all combinations of lighting control are performed for the entire system by simply storing floor patterns only for the connected load control terminals.

EXAMPLES Hereinafter, the present invention will be described with reference to one example.

(7) is transmission means provided in the central controller (1), and (8a) to (8c) are storage means provided in each of the floor controllers (2a), (2b) and (2c). A floor pattern indicating a combination of control contents of the connected load control terminals is stored. A plurality of floor patterns are set corresponding to the control signal transmitted from the transmitting means (7), (9a),
(9b) and (9c) indicate to the respective load control terminals based on the floor pattern corresponding to the control signal transmitted from the transmission means (7) among the floor patterns stored in the storage means (8). Control means for transmitting a control signal.

FIG. 2 is an explanatory diagram showing the correspondence between the floor pattern stored in each of the storage means (8a), (8b), and (8c) and the pattern set in the lighting system master unit (1). For pattern 1 of the system master unit (1), floor pattern 2 is set in the floor controller (2b).
Floor pattern 1 in the floor controller (2c)
Corresponds.

At this time, in the floor controller (2c), the floor pattern 1 is registered as a pattern for controlling lighting of the lighting devices (4j) (4k) (4l) (4m) collectively, and the floor controller (2b) registers the floor pattern 2 Is registered as a pattern for controlling lighting of the lighting devices (4g) and (4h) collectively.

FIG. 3 is a communication sequence diagram showing a communication operation of the lighting control system according to this embodiment.

 Next, the operation will be described.

Lighting control system When the lighting devices (4g), (4h), (4j), (4k), (4l), and (4m) are controlled collectively by control from the master unit (1) (hereinafter referred to as a pattern), the pattern The first operation request command is input to the lighting system master (1). From this command, the transmission means (7) sets a control signal to be transmitted individually for each of the floor controllers (2a), (2b), and (2c). In this example, a control signal indicating the floor pattern 2 for lighting control of the lighting devices (4g) and (4h) is sent to the floor controller (2b), and the lighting devices (4j) (4k) are sent to the floor controller (2c). )
(4l) A control signal indicating a floor pattern 1 for controlling lighting of (4m) is set. Then, the control signal of the floor pattern 1 is transmitted to the floor controller (2c). The floor controller (2c) detects its own address from among the control signals on the inter-floor controller transmission line (5) and receives this signal. Further, from the content of this signal, it is interpreted that the signal is the selection signal of the floor pattern 1, and then the control means (9c) sends a control signal based on the floor pattern 1 to the load control terminal (3g).

The load control terminal (3g) receives this control signal and controls the lighting equipment (4j) (4k) to supply power.

Next, the control means (9c) similarly transmits a control signal based on the floor pattern 1 to the load control terminal (3h), turns on the lighting devices (4j) and (4k), and controls each load control terminal. Is controlled to the state of the floor pattern.

Next, the transmitting means (7) transmits a control signal of the floor pattern 2 to the floor controller (2b). The floor controller (2b) detects its own address from among the control signals on the inter-floor controller transmission line (5) and receives this signal. Further, from the content of this signal, it is interpreted that the signal is the selection signal of the floor pattern 2, and from this, the control means (9b) first sends a control signal based on the floor pattern 2 to the load control terminal (3d).

Control to supply power to the load control terminal (4g).

Next, the control means (9b) similarly transmits a control signal based on the floor pattern 2 to the load control terminal (3e), controls lighting of the lighting equipment (4h), and sets each load control terminal to a predetermined value. Is controlled to the state of the floor pattern.

By doing so, the lighting system master unit (1)
Controls the lighting state of the entire system in accordance with the request command of pattern 1.

As described above, the floor pattern is set for each floor controller, and the control signal of the floor pattern is sent from the lighting system master unit (1) to each floor controller. Therefore, even when the overall lighting control is performed, the floor pattern is stored in each floor pattern. The maximum number of patterns to be saved becomes smaller. In addition, since the control contents can be managed hierarchically, it is not necessary to manage the control contents of each lighting device for all lighting system masters (1) in various cases, so that the burden can be reduced.

[Effects of the Invention] As described above, according to the present invention, the floor controller is provided with the storage means for storing the floor pattern of the combination of control contents when collectively controlling the load control terminals connected to each floor controller. Since the central control unit is provided with a transmission means for setting a floor pattern corresponding to each floor controller from an operation request input to the central control unit and transmitting the control pattern to the corresponding floor controller as a control signal, the control content is hierarchical. Since it is not necessary for the parent device to manage all combinations of control contents at the time of collective control, there is an effect that the burden is reduced.
