Description

Description: TECHNICAL FIELD The present invention relates to a telephone system used for home automation and the like.

[Prior Art] When an answering machine and a control terminal for load control are used and there are two or more office lines, one line is used for the control terminal and the other line is used for the answering machine. It takes the form of doing.

[Problem to be Solved by the Invention] In such a case, if there is a control terminal and an answering machine,
There was a problem that each line was required.

The present invention has been provided in view of the above points,
When the control terminal and the answering machine are connected,
It is an object of the present invention to provide a telephone system for performing two automatic call receiving operations without restriction of a line as intended by a caller.

Means for Solving the Problems The present invention is directed to an information line on which a telephone line is connected and a plurality of telephones are connected and a voice signal for telephone is superimposed and a data line on which data is superimposed. Home bus controller, an interface unit for connecting a telephone to the information line and the data line by a bus, and a control terminal for load control connected to the information line and the data line by a bus. A telephone system for controlling connection of a telephone and a control terminal to an information line via an interface unit by data processing, wherein a home bus controller responds to a call request from the caller by the telephone after receiving a call from the caller. When the input data by the push button signal is received from the interface unit via the data line, the input data is received. When the password is checked and matched with the password for the control terminal, the control terminal is connected to the information line and the interface unit is controlled to release the telephone from the information line.

[Operation] When the home bus controller receives input data by a push button signal from the caller from the interface unit via the data line after the telephone responds to the call request from the caller, The input data is collated with the password for the control terminal, and when they match, the control terminal is connected to the information line and the interface unit is controlled to release the telephone from the information line.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 3 shows a block diagram of a home bus system, in which a home bus controller (hereinafter referred to as a home bus controller) to which a line from a central office is connected.
HBC) 1 derives an information line L on which a telephone voice signal is superimposed and a data line D on which data is superimposed. A plurality of answering machines 2 are connected (bus-connected) to the information line L and the data line D via an interface unit (hereinafter referred to as IFU) 4. A control terminal 3 for controlling loads such as an air conditioner and lighting equipment is connected to the information line L and the data line D (bus connection) in the same manner as the answering machine 2.

FIG. 2 is a block diagram of the IFU 4 for the answering machine 2, wherein the data line D is a D line interface 41, a CPU 4
Oscillating circuit 43 for oscillating a 2,16Hz, the switching of the response detection circuit 44 for response detection answering machine 2, the relay contact R ₁ performs contact and separation between the information line L, the information line L side and the oscillation circuit 43 side relay contacts R ₂ performed, and a PB receiver 45 or the like for receiving a personal identification number using the push buttons from the caller.

Next, the operation will be described with reference to FIG. First, when an incoming signal of 16 Hz is received on the local line as shown in FIG. 1, the HBC 1 outputs an incoming signal as a packet 1 on the data line D as shown in FIG. The data IFU4 of this packet 1 is received, and the oscillation circuit 43 is controlled by the internal CPU 42 to output a 16 Hz signal to the answering machine 2 as shown in FIG. Then, the answering machine 2 responds by receiving 16 Hz as shown in FIG. The IFU 4 receives the response from the answering machine 2 at the response detecting circuit 44 and issues a connection request on the data line D as a packet 2 as shown in FIG. The HBC 1 receives the packet 2 and issues a connection permission as a packet 3 to the answering machine 2 as shown in FIG. Answering machine 2 receives the connection permission to閉結the DC circuit closes the relay contact R _1, as shown in.

In this state, when the caller wants to operate the control terminal 3, the personal identification number (PB signal) is input by a push button as shown in (1) and (2). IFU4 is
As shown in (1) and (2), the personal identification number from the caller is received by the PB receiver 45 as input PB data, and is sent to the data HBC1 as packets 3, 4, and 5 via the CPU 42 and the D line interface 41. The HCB1 determines that the password has been input as shown in (1) and collates. If the passwords match, an individual call is sent to the control terminal 3 as a packet 6.
The control terminal 3 receiving the incoming call, as shown in FIG.
, A connection request is issued as a packet 9. And HB
C1 issues a connection permission to the control terminal 3 as shown in FIG. As indicated by the connection permission, a normal response is performed thereafter. HBC1 issues a release request to IFU4 as shown in (1). The answering machine 2 is opened by opening the relay contact R _1. Since the control terminal 3 and the IFU 4 are connected to the information line L and the data line D via a bus, there is an advantage that the control place can be freely selected and the degree of freedom of the installation place is high.

[Effects of the Invention] As described above, the present invention is connected to a central office line from a telephone office and connected to a plurality of telephones, and an information line on which a telephone voice signal is superimposed and a data line on which data is superimposed. Home bus controller, an interface unit for connecting a telephone to the information line and the data line by a bus, and a control terminal for load control connected to the information line and the data line by a bus. A telephone system for controlling connection of a telephone and a control terminal to an information line via an interface unit by data processing, wherein a home bus controller responds to a call request from the caller by the telephone after receiving a call from the caller. When the input data by the push button signal of the interface unit is received from the interface unit via the data line, the input data is controlled. When the caller wants to talk on the telephone by checking the password with the password for the control terminal and if it matches, the control terminal is connected to the information line and the interface unit is controlled to release the telephone from the information line. The effect is that when the telephone answers and the caller wants to operate the control terminal, the control terminal responds, so that two automatic incoming calls can be performed as intended by the caller without line restrictions. Is played. In addition, since the control terminal and the interface unit are connected to the information line and the data line by bus, there is an advantage that the connection place can be freely selected and the degree of freedom of the installation place is high.
