G Embodiment One embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a home automation system (HA system) according to the present invention as a whole, and various electric devices such as a control panel 4, a lighting device 51, and a bus line 2 made of a coaxial cable through a distributor 3. 52, electric lock 6, security monitoring device 7, antenna 8, television receiver 9 and video tape recorder (VTR) 10, air conditioning equipment 1
1 etc. are connected directly or via adapters 5A, 6A, 7A, 9A, 10A, 11A.

The bus line 2 uses a frequency multiplexing method,
In addition to the received signal received by the antenna 8, for example, a control signal sent from a control device such as the control panel 4 is superimposed.

The control signal has a carrier frequency of, for example, 40 [KHz], and is composed of head data, a device code of a control destination, and a control command. For example, a control signal for turning on the first lighting fixture 51 is transmitted from the control panel 4. Then, bus line 2
All of the devices connected to the device receive the control signal, and the device code following the start data and the device code of its own match (the first adapter 5A in this case) analyze the following control command, The control operation (in this case, the ON operation of the first lighting device 51) is performed.

The adapters 5A, 6A, 7A, 9A, 10A, 11A comprise, for example, a micro computer and are not adapted to be directly connected to the bus line 2 of the HA system 1 (eg, luminaires 51, 52, electrical appliances). Lock 6, television receiver 9 etc.) is used to connect to the bus line 2 and has a memory with a built-in device code corresponding to each connected device and the device code in the control signal. It is composed of a relay switch or the like adapted to perform a predetermined control operation in accordance with a control command when it matches the built-in device code.

Further, in the embodiment shown in FIG. 1, not only the configuration of the conventional HA system 1 in which predetermined control signals are sent from the control panel 4 placed indoors to various electric devices, but also, for example, at the entrance side In addition to calling the interphone base unit 13 and calling function to the interphone slave unit 12 embedded in the outdoor wall, the remote control light receiving unit 14 is built in, and the infrared control signal received from the remote control commander 15 is used as a control signal. The data is converted and sent to the bus line 2. Thus, a predetermined indoor electric device 5 is used from the outside by using the remote control commander 15.
1, 52, 6, 7, 9, 10, 11 can be controlled arbitrarily.

In FIG. 2, the remote control commander 15 is a numeric keypad,
It has a keyboard 20 in which keys for control device codes, keys for control commands, etc. are arranged, and a command input from the keyboard 20 is received by a user's operation, for example, by a remote controller control unit 21 having a micro computer configuration. After a predetermined remote controller control signal is generated by the remote controller control unit 21, it is subjected to predetermined modulation and is sent as an infrared control signal from the light emitting unit 23 formed of, for example, an infrared light emitting diode through the drive circuit 22.

The infrared control signal is received by the light receiving unit 25 having a photodiode structure in the remote control light receiving unit 14, detected by the detection circuit 27 through the amplifier circuit 26, and then input to the control unit 28 having a microcomputer structure. Here the control unit 28
Has a memory number, for example, a four-digit number,
The infrared control signal that follows is sent to the bus line 2 as a control signal for the HA system 1 only when the code number input from the remote control commander 15 via the numeric keypad 20 is correct.

The display unit 24 of the remote control commander 15 is composed of, for example, one light emitting diode to indicate that the input operation from the keyboard 20 has been reliably performed, and the display unit 29 of the remote control light receiving unit 14 is, for example, Light emitting diode 4
The remote control commander 15 is configured to display the number of recitation numbers input.

In addition to the light receiving section 25 of 14 and the display section 29 consisting of four light emitting diodes, a small camera 33 using a CCD solid-state image sensor, an infrared sensor 36 including an infrared light emitting section 34 and a light receiving section 35 is built in. Thus, when a visitor or a suspicious person approaches the entrance, the infrared sensor 36 detects this and turns on the power of the small camera 33 and turns on the monitor TV 9 or VTR 10 provided indoors. This allows visitors or suspicious persons to be monitored or recorded.

In the above configuration, for example, when the user is going out with the whole family and is away from the house, the indoor control panel 4 is operated so that, for example, the television receiver 9, the air conditioner 11, and the lighting fixtures 51, 52 are unnecessary. Turn off the power of electrical equipment,
After locking the electric locks 6 such as the doors and windows of each room, go out from the entrance and operate the remote control commander 15 to lock the entrance 6, turn off the entrance lights 51, 52, and the security monitoring device 7. By switching the mode of (1) to the monitoring mode, the user can go out with peace of mind.

Further, for example, when returning to the absence home such as at night, when the user arrives in front of the front door, the user operates the remote control commander 15 to open the front door 6, turn on the front lights 51, 52, and the security monitoring device 7, for example. If you specify switching to the release mode etc.,
The user can enter the house in a safe atmosphere.

According to the above configuration, the remote control light receiving unit 14 is arranged in the interphone slave unit 12, and the infrared control signal from the remote control commander 15 is transmitted to the indoor bus line 2 as a control signal. A desired electric device can be controlled by using the remote control commander 15, and thus the HA system 1 that can significantly improve the usability for the user can be realized.

Further, according to the above-described embodiment, the interphone slave unit 12
By arranging the remote control light receiving unit 14 in the above, it is not necessary to perform new installation work, and the appearance is not spoiled.

In the above embodiment, the keyboard 20 of the remote control commander 15 is used to input an arbitrary device code and control command. However, in addition to this, for example, when going out (and returning home) to the remote control control unit. If a memory that stores the necessary control signals in advance is provided, and an exit key (and / or a home key) is further provided on the keyboard, and the out key (or home key) is pressed when going out (or going home), If the control signal that causes a plurality of electric devices to perform a predetermined operation is read from the memory and sent to the remote control light-receiving unit, the number of keyboard inputs when going out (or going home) is the minimum required. As a result, it is possible to virtually eliminate user's operation error. As a result, the usability for the user can be further improved.

In addition, in the above-described embodiment, the transmission method using infrared rays as the remote control commander and the remote control light receiving portion has been shown, but the present invention is not limited to this, and for example, visible light, radio waves, etc. may be used to realize the above-mentioned embodiment.
