Abstract

PROBLEM TO BE SOLVED: To control an electric appliance through a remote control by providing a master set for a cordless telephone set having an automatic call reception function and a message automatic reproduction function and a radio section in radio channel connection to a master set. SOLUTION: An unattended master set 3 preset to the remote control mode receives a phone call from an outdoor digital cordless telephone set 5, starts its automatic call reception function to receive the call, reproduces automatically a message relating to remote control in a memory and sends the message to the telephone set 5 through a telephone line and a public base station 4. When the telephone set 5 returns control code data to select an electric appliance 2 desired to be connected through the key operation, a radio calling is made to the selected electric appliance 2. The electric appliance 2 detects it that the appliance itself is selected, based on the control code data received by a radio section 1. Then the electric appliance 2 and the telephone set 5 are in a connected state and the electric appliance 2 is controlled remotely, based on the control code data from the telephone set 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for remotely controlling electric appliances such as home electric appliances.

[0002]

2. Description of the Related Art Conventionally, an infrared remote controller is mainly used as a remote controller, and the remote controller can be operated remotely by pointing the remote controller at a light receiving portion of an electric product such as a television and receiving infrared rays emitted therefrom.

[0003]

Conventionally, a person who operates a remote control is located near an electric appliance (within a range of about 2 to 3 m), and infrared rays emitted from a remote controller are free from obstacles. Can not be operated unless it reaches the light receiving part of.

It is an object of the present invention to provide a method for controlling an electric appliance by remote control even from a remote place.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention provides a base unit of a cordless telephone connected to a telephone line, having a function of automatically receiving a call and a function of automatically reproducing a message. A wireless unit that wirelessly connects to the device, and a control unit having a data input unit that is output from the wireless unit, comprising a built-in or externally mounted electrical product, wherein the base unit is an outdoor telephone. A procedure for automatically receiving an incoming call in response to a call, a procedure for automatically reproducing a message pre-stored in storage means by the base unit and transmitting the message to a telephone line, and a step in which the base unit transmits control data transmitted from an outdoor telephone to the wireless unit. A wireless remote control method for an electrical product, comprising: a step of wirelessly transmitting to a unit; and a step of outputting the control data from the wireless unit to a control unit of the electrical product through a data input unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a device according to an embodiment of the present invention, in which (a) is an image diagram of an electric product 2 which directly incorporates an RF module (radio unit) 1, and (b) is an RF interface. FIG. 1 shows an image diagram of an electric product 2 in which an RF module (radio unit) 1 is externally arranged. As the electric product 2, a product controlled by software such as a television, a video, and a personal computer is suitable.

[0007] By incorporating the radio section in this way, the electric product can be treated as one portable device, and can be linked to the parent device of the digital cordless telephone. In the case of FIG. 1B, by determining the interface, the RF module can be connected to any of the above-mentioned electrical products.

FIG. 2 is a system configuration diagram showing an embodiment of the present invention. An electric product 2 incorporating the RF module 1 shown in FIG. 1 and a home base unit 3 of a digital cordless telephone are arranged indoors. Base unit 3 has an answering machine function, and has a function of automatically receiving an incoming call for an answering call and automatically playing back a message stored in a memory in advance. In the present embodiment, a message for remotely controlling the electric appliance is stored in advance.

In FIG. 2, reference numeral 4 denotes a public base station arranged outdoors, which is connected to the base unit 3 through a telephone line. Reference numeral 5 denotes a digital cordless telephone, which is connected to the public base station 4 by radio and is connected to the base unit 3 via the public base station 4 and a telephone line.

With this system configuration, the master unit 3 performs the following control by built-in software.

The base unit 3, which is set to the remote control mode in advance and is away from home, is an outdoor digital cordless telephone 5
When a call is made from a telephone, an automatic call receiving function is activated to receive a call, a message relating to remote control in the memory is automatically reproduced, and the message is transmitted to the digital cordless telephone 5 through the telephone line and the public base station 4.

Base unit 3 waits for control code data from digital cordless telephone 5 in accordance with the transmitted message.

According to the above-mentioned message from master unit 3,
The digital cordless telephone 5 receives the control code data for selecting the electric appliance 2 to be connected by the key operation, and makes a wireless call to the selected electric appliance 2.
The RF module 1 is controlled by a control unit (software) of the electric product 2, and the electric product 2 detects that it has been selected from the control code data received by the wireless unit 1. Thereafter, the electrical product 2 and the digital cordless telephone 5 are connected, and the digital cordless telephone 5
Remote control of the electric product 2 is performed based on the control code data.

[0014]

As described above, according to the method for remotely controlling an electric appliance of the present invention, even when outdoors, an electric appliance such as a home or a work place can be remotely controlled from a digital cordless telephone or a public telephone connected to a digital line. it can. Further, according to the present invention, since remote control is performed wirelessly, there is no influence from obstacles such as infrared rays.
