Abstract

PROBLEM TO BE SOLVED: To shorten the processing time to control a luminaire from extension telephone sets fitted with function buttons by adding an information element for put-on and put-off of the luminaire within the packet signal for the call control. SOLUTION: A caller pushes the function button of extension telephone sets 2 and 7 to send out a function code for put-on or put-off of illumination which is set previously in a telephone exchange unit 3A. The calculational operating part of the exchange unit 3A searches the stored response table which specifies the luminaire to be controlled for each extension telephone set and selects the address of the luminaire 10 corresponding to the extension telephone set 2, 7 of the caller. The calculational operating part prepares a data packet in which the address of the luminaire and the put-on/put-off signal of the luminaire are combined, and sends it off for a luminaire controller 9 via a communication port 8 of the exchange unit 3A. The luminaire controller 9 controls the put-on and put-off of the luminaire 10 on the basis of the given packet signal.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control system for controlling lighting equipment and the like by an extension telephone of a private branch exchange.

[0002]

2. Description of the Related Art Conventionally, when equipment is controlled, a voice communication channel is used, and a signal is sent to a telephone controller by a push button. In this method, a signal is transmitted after a voice communication path is once secured, so that control takes time. Therefore, it is not suitable for equipment that requires a fast response, such as lighting equipment in a living room.

A configuration of a conventional lighting control system for controlling a lighting fixture by an extension telephone of a private branch exchange will be described with reference to FIG. FIG. 7 is a diagram showing a configuration of a conventional lighting control system.

In FIG. 7, reference numeral 1 denotes a caller (person making a call), 2 denotes an analog extension telephone, 3 denotes a private branch exchange, 4 denotes a telephone controller, 5 denotes a relay contact, and 6 denotes a start / stop facility.

FIG. 7 shows a system for starting and stopping a device using a private branch exchange 3 and a telephone controller 4 which have been conventionally used. This equipment is also used for starting and stopping lighting equipment.

[0006] The private branch exchange 3 used here is capable of exchanging voice when the caller 1 dials with the analog extension telephone 2. The telephone controller 4 is basically a device dedicated to receiving a call, and after a voice call with the caller 1 becomes possible, a push button signal (hereinafter, referred to as a “PB signal”) sent from the caller side. A predetermined operation is performed in accordance with the following. The device start / stop telephone controller 4 opens and closes the relay contact 5 according to the PB signal. The signal of the relay contact 5 is used as a start / stop signal of the start / stop equipment 6. When entering a building or the like, a signal is transmitted via a building management system (central monitoring panel).

Next, the operation of the conventional system will be described with reference to FIG. FIG. 8 is a diagram showing the operation of a conventional control system.

FIG. 8 is a flow chart showing how the caller controls the calling / stopping equipment. Referring to FIG.
This is a procedure in which the caller 1 connects to the telephone controller 4 via the private branch exchange 3.

[0009] This is basically the same as a normal voice communication procedure, but when the caller 1 dials, a PB signal ("x" in the figure) of the equipment ON is sent together with the extension number. I have. The telephone controller 4 uses a ringer from the private branch exchange 3 as a trigger to perform off-hook (incoming call).

In FIG. 1, step 2 is a processing procedure in the telephone controller.

The telephone controller 4 receives a PB signal for turning on the equipment from the private branch exchange 3 immediately after the off-hook. This signal is replaced with an operation signal of the relay in the PB receiver in the telephone controller 4 to operate the relay. (In some cases, a signal is transmitted directly from the telephone controller 4 to the calculation unit of the building management system.) The completion of the operation of the relay is returned to the caller 1 as a completion tone (sound tone) through the tone sender. Caller 1 confirms the dial tone and places the handset.

The telephone controller 4 can receive a facility ON signal after securing a voice communication path with the analog extension telephone 2 used by the caller 1. Therefore, it takes time from when the handset of the analog extension telephone 2 is raised to when the telephone controller 4 receives the PB signal.

[0013]

In the above-mentioned conventional lighting control system, a signal is transmitted after a voice communication path is once secured, so that it takes a long time to control and a fast response such as a lighting fixture in a living room. However, there is a problem that it is not suitable for equipment that requires the above.
