Abstract

PURPOSE:To control electric appliance of another room with simple operation from any room by providing a portable remote controller, installing a receiver for a device control signal to each room and connecting the receivers to a central controller. CONSTITUTION:When a control signal is outputted to photodetector sections B1-Bn of receivers A1-An of any room or to a photodetector section 6 of a central controller 4 from a remote controller 5, the control signal is supplied to a CPU 12 of the central controller 4, when the content of control is discriminated. Then according to the control content, ON/OFF of an electric appliance of each room is controlled. In this case, when a signal from the photodetector sections B1-Bn exists, the CPU 12 discriminates how and which electric appliance in which room is to be controlled, and drives a device control IF circuit 10 depending on the result of discrimination and sends the control information having an address of an object device to each adaptor. Thus, the electric appliance of another room or own room is central-controlled from any room.

Conventionally, in a centralized electrical equipment control system such as a home bus system, the electrical equipment in each room is controlled centrally at one location, and the data communication methods of each system are not fully utilized.

That is, in the conventional control system, electrical devices in each room can only be controlled by a central control unit attached to the wall of a living room or the like, or by a hand switch of each device. For this reason, for example, if you want to control an air conditioner in another room, such as in a bedroom, the same control unit must be installed in the bedroom as well.

(Problem to be solved by the invention) Conventional electric machine! The central control system is configured as described above, so if you want to control electrical equipment in another room, you have to go to that room or to the room where the central control unit is installed. There is a problem in that installing the same control unit in each room results in a complicated and expensive configuration.

This invention was made with a focus on these important points, and is a centralized control system for electrical equipment that is simple in configuration, allows each room to control electrical equipment in other rooms, and is easy to operate and inexpensive. The purpose is to obtain.

(Means for Solving the Problems) The electrical equipment centralized control system of the present invention is configured as follows.

(i) In a control system that controls electrical equipment installed in each room, a portable remote control device that wirelessly transmits a control signal for the electric #I device in each room is provided, and the control signal is transmitted to each room. A receiver was installed to receive the data, and a central control unit was installed to centrally control the electrical equipment in each room based on the IIJ control signal input from the remote control unit to the receivers (three units) in each room.

(11) In the electrical equipment centralized control system of (i) above, the control signal transmitted from the remote control device to the receiver in each room.
The J4 signal was an optical signal.

(iii) In the electrical equipment centralized control system of (i) or (ii) above, the receiver in each room is housed in the same housing as the telephone or modular installed in that room, and the telephone communication control wiring is The control I signals for the electrical equipment in each room are superimposed on the signal and transmitted to the central control unit.

(iv) In the electric equipment centralized control system of (i) or (ii) above, the receiver in each room is housed in the same casing as the light switch in that room.

(v) In the electric AS facility control system of item (j) or (ii), the receiver in each room is housed in the same housing as the light switch in that room, and the remote control device is The signal is superimposed on a telephone installed in the room or on a modular telephone communication control wiring and is transmitted to a central control unit.

[Function] In the electrical equipment centralized control system of the present invention, electrical equipment in other rooms can also be controlled by emitting a control signal fε from a portable remote control device to one of the receivers installed in each room. can do. In addition, wiring can be reduced by installing a receiver on a telephone or modular to superimpose control and control signals on the control wiring for telephone communication, and by installing a receiver on a light switch, it is possible to receive This prevents the machine from being hidden behind furniture, etc.

FIG. 1 is a block diagram showing an embodiment of the present invention. This system consists of an air conditioner 1, lighting lights 2, etc. installed in each room.
Central control device 4 that centrally controls electrical equipment such as electricity 123
and a portable remote control device 5 that wirelessly transmits control signals to those electrical devices, and each room also has a receiver A+ connected to the central 171Ml device 4 through two information lines.

A, ,---A, are arranged.

The electrical equipment in each room above has its own adapters la, 2a,
It is connected to a central control device M4 via 3a, and the central control device 4 is provided with a light receiving section 6 for an optical signal (control signal) and a display section 7.

Further, the remote control device 5 is provided with a keyboard 8 for inputting control commands for the electric JIl equipment in each room, and a light emitting unit 9 having an infrared light emitting diode and the like for transmitting the control signal as an optical signal. , receivers A, , A2 ., in each room.・
...-A, there is a light receiving section Bl that receives the signal light,
B2. ...Bn is provided. And these receivers A, , A2 . -------The central control device 4 controls the electrical equipment in each room based on the control signal from the remote control device 5 inputted to An.

FIG. 2 is a block diagram showing the internal configuration of the central control device 4. As shown in FIG. In the figure, 10 is an equipment control IF (interface) circuit for controlling electrical equipment in each room, and 11 is a light receiving circuit connected to receivers A1 to An in each room. F circuit, 1
2 is a CPU that controls the entire system; 13 is a display control circuit that controls the display section 7; and 14 is a power supply circuit that supplies power to each circuit.

In the system configured as described above, the light receiving units 8 of the three receivers A, ~An in any room are transmitted from the remote control device 5.
1 to B, or when a control signal is output to the light receiving section 6 of the central control device 4, the control signal 43 is output to C of the central control device 4.
The information is taken into the PU 12, and the control content is determined here.

Then, the electrical equipment in each room is turned on or off according to the control content. At this time, the light-receiving IF open circuit 1 sequentially polls the light-receiving sections B, -Bn in each room, and constantly checks whether there is a signal from the light-receiving sections B, -B. Then, when there is a signal from the light receiving sections 81 to B, C
