Abstract

PROBLEM TO BE SOLVED: To deliver a call to a resident while avoiding useless calling by calling only places where the resident is present in the case of the calling by an intercom and of the arrival of an incoming call. SOLUTION: In a home telephone system, a visitor-use intercom 2 is provided to an entrance, and each room is provided with a telephone set 1 and a master unit 4 controls the telephone sets, to which the doorphone and an external line are connected. A human body sensor 6 is connected to each telephone set 1, acoustic units 5 with a human body sensor are placed in rooms and corridors without the provision of the telephone set 1 and the master unit 4 controls each telephone set 1 to which the human body sensor 6 is connected and the acoustic units 5 with a human body sensor. When a call signal from an external line or the intercom 2 is given to the telephone sets 1 and acoustic units 5 with 2 human body sensor via the master unit 4, only the telephone sets 1 whose human body sensor 6 senses a human body and the acoustic units 5 with human body sensor sensing a human body ring the call tone from the intercom 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home telephone system and, more particularly, to a home telephone system which transmits a ringing tone only to a place where a resident is located, based on an input signal of a human body sensor.

[0002]

2. Description of the Related Art A conventional home telephone system is shown in FIG. This home telephone system is composed of a door phone 19 installed at the entrance, a telephone 21 for each room, and a main device 20 for controlling them, and when the call button 22 of the door phone 19 is pressed or an outside line is received, the main device is set. The call signal is transmitted from the telephone 20 to the telephone 21, and the telephone 21 receiving the call signal from the main device 20 sounds a ringing tone.

[0003]

However, since the conventional home telephone system is configured as described above, when a call is made from an outside line or a door phone, the ringing sound is made only in the room where the telephone is installed. I do.
Therefore, in the case of the system as shown in FIG. 3, the ringing volume is appropriate in the room where the telephone is installed, but it is difficult to recognize the ringing tone in other rooms or hallways where the telephone is not installed due to insufficient volume. It is possible that
That is, when the resident is only in a place other than the room where the telephone is installed, there is a disadvantage that the ringing may not be recognized.

[0004] Further, when the ringing volume is set to a high volume in order to solve the above-mentioned disadvantage, the ringing volume in the room where the telephone is installed becomes extremely large, resulting in an inappropriate ringing volume. . The present invention has been made in order to solve the above-mentioned drawbacks. An acoustic device and a human body sensor are provided at various places in a dwelling unit to make a call only at a place where a person is present, eliminating unnecessary calls and reliably informing the resident of the call. It aims to provide a home telephone system that can be used.

[0005]

In order to achieve this object, a home telephone system according to the present invention has a door phone for a visitor at the entrance and a telephone in each room, and is controlled by a main unit connected to the door phone and an outside line. In a home telephone system, a human body sensor is connected to a telephone, an audio device with a human body sensor is provided in a room or hallway without a telephone, and the main device controls the telephone connected to the human body sensor and the audio device with a human body sensor. When a call signal from an outside line and a door phone is sent to the telephone and the sound device with a human body sensor via the main unit, only the telephone set that has reacted to the human body with the human body sensor and the sound device with the human body sensor that has reacted to the human body are transmitted from the outside line and the door phone. Ringing tone. According to such a home telephone, by calling a place where a person is present, it is possible to reliably notify the resident of the call.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a home telephone system according to the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, in a home telephone system according to the present invention, a call signal transmitted when a call button 3 of a door phone 2 is depressed, or a main device 4 which has received an external line call transmits a call signal to a telephone 1 to sound a ringing tone. It is a home telephone system to be operated. In this system, a human body sensor 6 is incorporated in a telephone, and an acoustic device 5 with a human body sensor is provided in various places.
Is provided, and the telephone 1 having the human body response by the human body sensor 6 or the acoustic device 5 with the human body sensor having the human body response by the human body sensor 13 sounds a ringing tone.

In the telephone 1, when a call is made from an outside line or a door phone 2, a call signal transmitted from the main unit 4 is received by a call signal receiving unit 8 via a telephone function unit 7, and the CPU
The signal is output to 10. The CPU 10 is a call signal receiving unit 8
From the human body sensor 6 via the human body sensor I / F 9, a signal is sent to the sound generation circuit 11 if there is a human body response, and the speaker 12
Sends a ringtone.

[0008] In the acoustic device with a human body sensor 5, when a call is made from an outside line or the door phone 2, a call signal sent from the main device 4 is received by the call signal receiving unit 14 and a signal is output to the CPU 16. The CPU 16 receives the signal from the call signal receiving unit 14, checks the presence or absence of a human body reaction from the human body sensor 13 via the human body sensor I / F 15, and sends a signal to the sound generation circuit 17 when there is a human body reaction, and 18
Sends a ringtone.

The determination of the ringing tone transmission by the telephone 1 or the acoustic device 5 with a human body sensor is performed by the processing shown in the flowchart of FIG. First, the presence or absence of a call signal from the main unit is confirmed (FT2). If the call signal is confirmed, the process proceeds to the confirmation of the presence or absence of a human body reaction by a human body sensor (FT3). The presence or absence of a call signal from the device is confirmed (FT2). A ringing tone sounds if a human body reaction is detected in the confirmation of the presence or absence of a human body reaction (FT
4) If there is no human reaction, the presence or absence of a call signal from the main device is confirmed again (FT2).

[0010]

As is apparent from the above description, according to the home telephone system of the present invention, when a door phone is called or an incoming call is received from an outside line, a telephone having a human body reaction by a human body sensor or a sound device with a human body sensor sounds a ringing sound. By doing so, unnecessary calls can be eliminated, and the calls can be reliably transmitted to residents.
