BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for home automation and the like, and has a remote control function P for remotely operating household electric appliances and the like using a telephone line or the like.
Regarding HS (Personal Handyphone System).

[0002]

2. Description of the Related Art With the progress of home automation technology, a technology for remotely controlling home electric appliances such as an air conditioner and a video deck by using a telephone line has been rapidly developed in recent years.

Conventionally, as a technique related to this type, there has been one as shown in FIGS. 4, 5, 6, and 7, for example.

FIG. 4 is a block diagram showing a configuration example of a conventional remote control system (first conventional example).

In this remote control system, an electric device 106 is placed indoors from a remote place (for example, whereabouts).
To operate, the telephone 101 first sends a tone signal or a voice signal to the telephone line 101a. This signal is received by the telephone 103 via the telephone network 102, and then sent to the decoder device 104 via the signal line 103a to be decoded. Then, the control device 105
Operates the electric device 106 via the signal line 106a according to the decoding result.

On the other hand, from a short distance (indoor), the electric device 106
When operating, the control unit 105 is operated or the electric device 106 is operated directly.

FIG. 5 is a block diagram showing a remote control system disclosed in JP-A-4-11436 (second conventional example).

This remote control system uses a cordless telephone, and its base unit 201
Is provided with a function of sending a command signal, which is sent from a caller in a remote place via a telephone line 201a and indicates the on / off operation of an electric device, to the slave unit 202 side, and the slave unit 20.
A switch circuit 202a for controlling on / off of an electric device supplied with commercial power is provided on the second side, and the switch circuit 2a.
02a is provided with a control circuit 202b for performing on / off control based on the command signal.

The command signal sent from the caller through the telephone line 201a is received by the receiving circuit 202c on the slave unit 202 side via the master unit 201 and sent to the control circuit 202b. The control circuit 202b determines the command signal,
A control signal is output to the switch circuit 202a based on the determination result. Then, the switch circuit 202a turns on / off the commercial power supply of the electric device according to the control signal.

FIG. 6 is a block diagram showing a remote control system disclosed in Japanese Patent Laid-Open No. 5-176366 (third conventional example).

This remote control system also uses a cordless telephone and has a telephone line 300.
A cordless telephone having a base unit 301 connected to the base unit 301 and a handset unit 302 wirelessly connected to the base unit 301. Then, on the load 303 side, the wireless signal receiving device 30
4 and a switching control device 306 connected between the power line 305 and the load 303.

The load control signal sent from the caller via the telephone line 300 is sent to the base unit 301 of the cordless telephone via the telephone line 300, and is transmitted from the base unit 301 to the receiving device 304 by radio waves. . The receiving device 304 receives this signal and sends it to the switching control device 306, and the switching control device 306 opens and closes the power supply to the load 303 in response to the load control signal. In addition, the child device 302 is also the parent device 30.
Like No. 1, it has a function of transmitting a load control signal.

FIG. 7 is a block diagram showing a remote control system disclosed in JP-A-7-107186 (fourth conventional example).

This remote control system is
It uses a HP (Personal Handy Horn). Note that PHP is an initial name of PHS, and hereinafter, it will be described as PHS. Normally, cordless phones can only be used indoors or near, but P
The HS can be used outdoors as a simple mobile phone, and can be freely used in a service area through small outdoor wireless base stations (PHS base stations) 400A installed in the telephone network 400 in large numbers. .

In the remote control system of the fourth conventional example, the PHS main unit has a modem 401,
A personal computer 402 and a HIS (Home Information System) interface 403 are connected to each other, and various electric devices to be controlled are connected to the HIS interface 403 by wire.

When controlling electric equipment from a long distance (for example, away from home), control data is transmitted from the PHS slave unit 410, and the control data transmitted through the PHS base station 400A and the telephone network 400 is transferred to the modem 401. It is sent to the personal computer 402 via. The personal computer 402 decodes the control data and controls the operation of the desired electric device based on the control data.

[0017]

However, the above conventional example has the following problems.

(1) In the first conventional example (FIG. 4), it is necessary to provide a signal line indoors from the telephone 103 to the electric device 106 to be controlled via the decoder device 104 and the control device 105. . Furthermore, the user needs to learn two types of operation methods (for long distance and for short distance) depending on the distance to the electric device 106, and the operation method is complicated.

(2) In the second conventional example (FIG. 5), the problem (signal line facility) of the first conventional example is improved by using the cordless telephone, but the telephone line is used. Remote control is not possible from indoor locations without a telephone connected to. Therefore, in such a case, it is necessary to directly operate the electric device, and as a result, the operation method becomes complicated as in the first conventional example. As a method of improving these problems, a method of using a mobile phone can be considered, but there is a problem that a mobile phone call charge is incurred despite a short distance and running cost becomes high.

(3) In the third conventional example (FIG. 6) using a cordless telephone, the radio signal receiving device 3 is provided on the load side.
04 and the opening / closing control device 306 are provided so that the load 303 can be operated wirelessly from the slave unit 302, so that the problems of the first and second conventional examples can be improved. However, the wireless signal receiving device 304 and the switching control device 30 are newly added.
6 was necessary, and there was a problem in terms of installation location and cost.

(4) In the fourth conventional example (FIG. 7), P
Since the HS is used, if the transceiver function is used, remote control can be performed at a lower cost than a mobile phone even at a short distance (indoor). However, since a personal computer or the like is used, the remote control device becomes large in scale, and there are problems in terms of space and cost. Further, since a large number of electric devices are connected to the remote control device by wire, it is necessary to install the signal line indoors.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide a PHS with a remote control function which does not require installation of a signal line facility or a new wireless receiver.
