Abstract

PURPOSE:To attain remote control of a lighting equipment or an airconditioner or the like by utilizing effectively the existing connecting operation of private automatic branch exchange. CONSTITUTION:When the operator makes a dial from a nearby pushphone telephone set STA.A, a private exchange branch PABX connects the pushphone telephone set STA.A and an instrument power supply controller SW.CON through the known local connection to transmit a call signal. When the controller SW. CON receives the said call signal for a prescribed time with the operation of an automatic response device ANS, the controller is subjected to ring trip and transmits a response signal such as a tone to the pushphone telephone set STA. A. Then the operator dials a number (code) corresponding to an electric device desired to be controlled and an on/off designation code of power supply by the pushphone dial. This code is analyzed by a pushphone signal analyzer PAN and a prescribed electronic switch ESW is driven.

The equipment power switch and intermittent signal are sent to the premises electrical equipment power supply control device to control the premises electrical equipment.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram for explaining the present invention, and shows a case where a button telephone and a domestic electrical equipment power supply control device are connected.

In FIG. 1, STA@A is a button telephone. LRGa is this Butshuhon telephone 5TA-A
The line circuit LRGb connected to the on-premises electrical equipment power supply control device (hereinafter referred to as equipment power supply control device) SW
-Line circuit connected to CON, NW is line circuit L
The circuit network connected to RGa, LRGb and the intra-office connection trunk IOT, cPu, is a central control unit that controls this circuit network NW, and these constitute an automatic private branch exchange (hereinafter referred to as a private branch exchange) PAB X. There is. DR is the door control device, LT is the lighting equipment, M
T is a music device, these are Butsuphone telephones 1
This is an on-premises electrical equipment that operates based on the specification of a button signal from sTA-A.
The configuration is such that ON/OFF of the power supply is controlled by CON.

In the device configured in this way, private branch exchange mPAB
Since the operation of the Power control device SWΦCO
Make an outgoing connection to N.

FIG. 2 is a block diagram showing an embodiment of the present invention, in which a portion related to the equipment power supply control device 5W-CON of FIG. 1 is extracted and shown.

In Fig. 2, the same numbers as in Fig. 1 indicate corresponding parts, and AC is an air conditioner that forms the controlled equipment, and together with the door opening/closing control device DR, lighting equipment LT, and music equipment Wt, MT, it is the Yokouchi electrical equipment. It consists of

Then, the equipment power control device SW@C connected to the subscriber circuit LRG of the automatic private branch exchange PABX (see Figure 1)
ON is an automatic answering device ANS that automatically responds to a calling signal, and a button signal analysis device that analyzes a button signal that specifies an electronic switch to be controlled from a button telephone STA-A (see Figure 1). Message: PA
N, and an electronic switch E8W which works in conjunction with the button signal analysis device PAN to control the on/off of power to the electric equipment in the premises specified by the button signal. In addition, A.

B is connected to the subscriber circuit LRG t+ZI A 1M and Bi? 1 is a lot.

Next, the operation of the embodiment shown in FIG. 2 will be explained with reference to FIG.

First, when controlling the power supply of premises electrical equipment, which is the equipment to be controlled, the operator must call the nearest Butshuhon telephone 5TA.
eA (see FIG. 1), and after making a connection, dial the subscriber number given to the equipment power control unit 5W-COH. When the subscriber number is dialed, the private branch exchange PABX shown in FIG. Send a signal.

Next, in this equipment power supply control device SW-CON, when the automatic answering device AN8 is activated and a calling signal is received for a certain period of time, a ring trip is performed and a response such as a tone is sent to the button telephone STA@A (see Fig. 1). Send a signal. The operator of the telephone 5TA-A who confirmed this response signal dialed the telephone.
Dial the number (code) corresponding to the electrical device you want to control and the power on/off designation code. The button signal from the button telephone STA@A is analyzed by the button signal analyzer PAN of the equipment power supply control unit [sw@coN, and a predetermined electronic switch ESW is driven. Based on the driving of this electronic switch layer, a controlled device, ie, a domestic electrical device, such as a door control device DR, is opened.

When the operation of the electronic switch ESW is completed, an operation completion signal such as a tone is sent from the equipment power control device SW/CON to the butshuphone telephone STA/A shown in Fig. 1, and the operator is instructed to Notify that control is complete.

Thus, by using the on-premise electrical equipment power control method of the present invention, it is possible to open the door, turn on the lights, and turn on the AC of the air conditioner by operating a button telephone just before a meeting is held, such as in a conference room in a company. It is easy to operate.

It can also be used as an automatic private branch exchange for hotels to control various electrical equipment in guest rooms from an office extension telephone.

〔Effect of the invention〕

As explained above, according to the present invention, the existing connection operation of an automatic private branch exchange is effectively utilized without using complicated means, and the subscriber line of the private branch exchange is connected to the power supply control device for electric equipment for the premises. This simple configuration allows fine-grained on/off control of electrical equipment from a remote location, and also prevents wasted energy, so the practical effects are extremely significant.
