Next, the operation of the first embodiment will be described.

First, the operating environment is set. In order to store the remote control control signals used in the remote control electrical appliances 8 and 9 in use in this embodiment in advance, infrared control signals are transmitted and received by infrared rays from a predetermined remote control device of the remote electrical appliances 8 and 9 in use. It is sent to the section 23. The information received by the infrared transmitter / receiver 23 is notified to the remote controller control signal analyzer 25 in order to analyze the remote controller control signal. The information analyzed by the remote control control signal analysis unit 25 is stored in the remote control control signal storage unit 26.

After setting the above operating environment, the remote control control electric appliances 8 and 9 can be controlled remotely via the telephone line network 5.

First, in order to perform remote control, the telephone number of the telephone 6 to which the control signal generator 2 is connected is input from the input unit 11 for inputting the required operation of the control request device 1 and the response from the telephone 6 is received. The requested operation information input by the rear input unit 11 is notified to the PB signal transmission unit 12 and converted into a PB signal that can pass through the telephone line network 5. This PB signal is notified to the voice signal switching unit 21 via the telephone network 5. The voice signal switching unit 21 distinguishes whether the input information is a voice or a PB signal, and if it is a voice, it connects to the telephone 6.

If the signal is a PB signal, the tone analysis unit 22 converts the signal into control information. This control information is notified to the remote control control signal generator 24. In the remote control control signal generation unit 24, the analysis information of the control of the remote control control electric appliance 8 accumulated in the operating environment is stored in the remote control control signal storage unit 26.
From the PB signal analysis unit 22 to generate a control signal that matches the control information.

The generated control signal is notified to the infrared transmitting / receiving unit 23, and the infrared transmitting / receiving unit 23 transmits the same infrared control signal as that of the remote control device for the remote control control electric appliance 8. With this infrared control signal, the remote control control electric appliance 8 operates in the same manner as an instruction from the remote control device.

Further, in the first embodiment, the infrared transmitter / receiver 31 of the control signal relay device 3 located between the infrared transmitter / receiver 15 and the remote controller control electric appliance 9 is also used for the remote controller control electric appliance 9. Communicate information as follows:

The infrared control signal transmitted from the infrared transmitter / receiver 23 is once received by the infrared transmitter / receiver 31. This control signal is temporarily stored by the remote control signal storage unit 21. At the same time, the infrared transmitter / receiver 31 notifies the remote controller control signal synchronization output unit 33 of the reception state, and monitors the presence or absence of the infrared control signal in space.

When it is confirmed that the control signal does not exist in the space, the remote controller control signal synchronization output unit 33 obtains the control signal stored in the remote control signal storage unit 32 and notifies the remote control signal amplification unit 34 of it. .. The control signal is shaped and amplified by the remote control signal amplifying unit 34, and then notified to the infrared transmitting / receiving unit 31. The infrared transmitter / receiver 31 converts the signal into an infrared control signal again to control the remote control electrical appliance 9
The remote control control electric appliance 9 operates in the same manner as an instruction from the remote control device for the remote control control electric appliance 9.

Next, a second embodiment of the present invention will be described.

In the case of the electric appliance 10 without the remote controller as shown in FIG. 2, the infrared power controller 4 can control the power supply. That is, the infrared transmitter / receiver 23 and the infrared transmitter / receiver 41 of the infrared power control device 4
By transmitting an ON or OFF control signal to the electric appliance 10, the infrared control signal is received by the infrared transmitting / receiving unit 41.

Based on this received information, the power control unit 42 connected to the AC power line 7 determines whether to supply or cut off power to the electric appliance 10. Since the electric appliance 10 is supplied with electric power via the electric power control unit 42, the electric appliance 10 can be controlled.

[0023]

As described above, according to the present invention, a control request device converts a control request for an electric appliance into a voice frequency control request signal, and then sends the control request signal through a telephone network to receive the control request signal. The control signal generation device converts the control request signal into a predetermined infrared control signal and sends it to the electric appliance for control, and for the electric appliance in a place where infrared rays do not reach directly, it passes through the control signal relay device. By controlling the electric appliances by using the infrared rays, the infrared rays used by the electric appliances can be utilized, so that there is no need to install cables as in the conventional case, and an economical remote control system can be realized. Further, since no cable is installed, there is an effect that it is possible to easily cope with changes in electrical appliances.
