Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the configuration of an in-building lighting control system using an electronic exchange.

(Prior Art) Conventionally, as a reference document of technology in this field, there is, for example, one disclosed in Japanese Patent Publication No. 56-42037J.

Generally, lighting equipment in offices in buildings is installed on the ceiling, and the lighting equipment is turned on and off by pulling a cord attached to the lighting equipment or by turning on/off a control switch installed on the wall. I was worried.

(Problem to be solved by the invention) However, in either case, there is a drawback that the lighting can only be controlled at the location where the cord or switch is installed, and the one-wall switch method requires indoor control to be performed up to the wall switch. be.

Therefore, in large buildings, 1. This indoor wiring piping and installation and wiring of switches required a lot of cost and man-hours.

(Means for Solving the Problems) The present invention was made to solve these problems, namely, to eliminate the switch from the wall surface,
In order to eliminate the need for indoor wiring to the switch, this lighting control system is configured to control the blinking of lighting equipment by pressing a button on a multi-function telephone connected via an electronic exchange installed in the office.

(Operation) In the present invention, a private branch exchange converts a control dial from a multi-function telephone into a control code, and then sends it to the main controller using an empty line of a transmission line consisting of a plurality of lines. The main controller analyzes the control code to identify the lighting equipment to be controlled, and uses a relay board to control the lighting equipment, thereby eliminating the above problem.

(Example) FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, 1 is a multi-function telephone, 2 is an electronic exchange, 3 is an interface circuit between the electronic exchange 2 and the main controller 4, 5 is a sub-controller, 6 is a relay board, and 7 is a lighting device. However, 7 does not mean one illumination light, but a group of illumination lights that are always turned on and off at the same time due to indoor wiring.

A large number of multifunction telephones 1 are installed in an office to facilitate lighting control, and the interface circuit 3 statistically calculates the number required to simultaneously transmit and receive lighting control signals. The sub-controller 5 is installed on each floor or within an area divided into fire prevention areas, etc., and there are no more than 10 lighting devices, which is called a zone. The same number of relay boards 6 and lighting devices 7 as sub-controllers 5 are installed.

Although multiple feature phones can be installed within one zone, a feature phone can only control lighting equipment within its own zone. That is, a single multi-function telephone can control up to 10 lighting devices.

In FIG. 1, a multifunction telephone 1-1 and a lighting device 7-1
0 to 7-19 are in the same zone.

be.

The multifunction telephone 1 is provided with a push button for controlling lighting.
A 3- to 5-digit number (hereinafter referred to as a control dial) is preset for each push button with a lighting control code and control device combination code.
It is registered in .

Since the contents of this control dial are the same for all multifunction telephones 1, it is not possible to identify the lighting equipment to be controlled by the control dial. The electronic exchange 2 converts the control dial and the calling class (the zone number is included in the class information) information of the multifunction telephone 1 into a control code. The control code is
It consists of two-digit 70-ar information, one-digit zone information, and the required number of lighting equipment numbers to be controlled (maximum 10), and keywords for tamper prevention can be added as necessary. FIG. 3 shows an example of the structure of the control code.

FIG. 4 shows examples of combinations of push button numbers (corresponding to control dials) and numbers of lighting devices to be controlled. For example, lighting devices controlled by push button 1 are 0# and 1? 1
N, and up to 10 lighting devices can be controlled in any predetermined combination with one push button.

In addition, in this embodiment, since the control code does not include a control signal for whether to QN or turn off the lighting equipment,
The system is constructed so that lighting equipment that is turned on is turned off, and lighting equipment that is turned off is turned on. However, adding push buttons to the multi-function telephone and adding on or off information is not possible in this example. It is easy to upgrade the system.

Next, an outline of the operation in this embodiment will be explained.

After taking the multifunction telephone 1-1 off-hook and hearing the dial tone from the electronic exchange 2, when one of the push buttons for lighting control is pressed, the pre-registered control dial sends a PB double signal to the electronic exchange 2. Sent out. The electronic exchange 2 converts the control dial received from the multifunction telephone 1 into the above-mentioned communication control code, selects one of the available interfaces 3, starts the main controller 4, and then converts the control code. Transmit the PB signal. Since the main controller 4 may receive control codes from multiple interfaces 3, the sending item number of each control code is determined and the sub controller 5
-1 to 5-r sequentially. Sub controller 5-1
From 5-r are multi-drops on the same transmission line.

! The signal transmission method from the main controller 4 is based on known technology (for example, Japanese Patent Publication No. 56-420).
37), detailed explanation will be omitted. Also,
Each of the sub-controllers 5-1 to 5-r extracts floor information and zone information from the control code received from the main controller 4, and determines whether it is in its own zone. In the case of another zone, the control code is discarded, and in the case of the own zone, the lighting device to be controlled is extracted from the control signal, and the switch corresponding to the corresponding lighting device on the relay board 6 is driven. When the switch is driven, the relay contact of the relay panel 6-1 changes from ON to OFF' or O as shown in Fig. 5.
It changes from FF to ON, and the lighting equipment turns on or off.

From the above explanation, if the building size is small, it is possible to reduce the number of interfaces from 30 to one, and
When the number of 50 sub-controllers is one, it is also possible to configure the main controller 4 and the sub-controller 5 as one set of controllers.

(Effects of the Invention) As explained above, according to the present invention, the 0N1
In order to make it possible to perform 0FF from the nearest telephone, wall switches are eliminated from buildings and offices, and piping and wiring to the switches are also eliminated. Therefore, there is an economical effect on the construction of the building.

Additionally, when changing the combination of switches and lighting equipment, it was previously necessary to change the indoor wiring;
By implementing this invention, changes can be easily made by simply changing the data within the electronic exchange.

This point will have a significant effect in the future, considering that in tenant buildings, interior partitions are often changed due to tenant changes.

In addition, in daily life, eliminating the need to do things like cleaning the walls in the morning and evening will reduce the number of ``residents'' and ``chores'', and produce a psychological effect. Since the controller unit can monitor all lighting conditions, it has the advantage of making building management easier.
