Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an interfon device, particularly one that notifies a visitor of the absence of a household member.

(Prior art) Conventionally, as an interfon device as described above,
For example, it is disclosed in Japanese Patent Application Laid-Open No. 61-84146.
According to this, an absence switch, an absence confirmation lamp, etc. are installed, and by turning on the absence switch when you are away from home, the absence confirmation lamp indicates to visitors that your family member is absent. I can let you know.

(Problems to be solved by the invention) In the above-mentioned conventional technology, it is necessary to operate the absence switch, and if this is neglected or forgotten, there is a problem that correct information cannot be conveyed to the visitor. Operating the absence switch was quite a hassle.

(Means for Solving the Problems) The present invention solves the above-mentioned conventional problems, and when a ring switch that notifies a ringer is operated a set number of times within a set operation interval, a household member It is characterized in that it determines that the person is absent and outputs a preset message.

(Example) The present invention will be described in detail below based on Examples. The drawing is a block circuit diagram showing an embodiment of an interphone device according to the present invention.

Microphones 2, 10, mixers 4, 12, amplifier 6,
14 and speakers 8 and 16 constitute a pair of transmitting/receiving circuits, thereby enabling bidirectional transmitting and receiving.

The call switch 18 outputs an operation signal A in response to an external operation, and the call switch 18 outputs an operation signal A in response to an external operation.
0, the timer circuit 22, and the counter 24, respectively. In response to the output of the operation signal A, the ringing signal generating circuit 20 supplies an audible signal for ringing notification to the mixer 4, and outputs an audible signal to the mixer 4,
6 to notify the ringing tone. That is, in this embodiment, the mixer 4,
The amplifier 6 and the speaker 16 serve as a ring tone notification circuit.

When the operation signal A is output, the timer circuit 22
The Q output of the FF 26 becomes "H" and the output becomes "L", the reset of the counter 30 is canceled via the OR gate 28, and the clock signal φ ₁ from the oscillation circuit 32 is outputted from the AND gate 34.
Therefore, the counter 30 starts counting the clock signal φ ₁ , and when a set time, for example 8 seconds, has elapsed, it outputs a timer signal and resets the counter 24 and FF 26 via the OR gate 36 . And FF
When 26 is reset, the Q output becomes "L" and the output becomes "H", counter 30 is reset, AND gate 34 is closed, and output of clock signal _φ1 is stopped. But counter 3
Since the operation signal A is supplied to the reset terminal R of 0 via the OR gate 28, the counter 30 is initialized with the output of the operation signal A, and the call switch 18 is operated within the set time. If so, the timer signal will not be output.

The counter 24 is initialized by the timer signal, and outputs the detection signal B when the operation signal A is counted by a set number, for example, "3".

When the audio signal generation circuit 38 outputs the detection signal B, the Q output of the FF 40 becomes "H".
The voice synthesis circuit 42 becomes active and generates voice data.
An audio signal is output based on the audio data from the ROM 44. The audio data ROM 44 stores audio data such as "I'm away at the moment", and the synthesized audio signal is passed through the low-pass filter 4.
6 to the mixer 12. Therefore, the audio signal is further supplied to the speaker 8 via the amplifier 14, so that the speaker 8 broadcasts a message such as "I'm away at the moment." That is, this embodiment outputs a message to the effect that the user is away by voice, and the mixer 12, amplifier 14, and speaker 8 are used together with the voice signal generation circuit 38 to form a message output circuit. When the predetermined voice synthesis operation is completed, a termination signal is output from the voice synthesis circuit 42, so the FF 40 is reset via the OR gate 48, and the voice synthesis circuit 42
operation stops.

The hook switch 50 outputs "H" when the receiver (not shown) is on, and "L" when the receiver is off, and the output is supplied to the OR gates 36 and 48 via an inverter 52. In other words, in this embodiment, when the handset is off,
Since the FFs 26 and 40 and the counter 24 are held in the reset state, the timer circuit 22 and the counter 2
4 and the audio signal generating circuit 38 are prohibited from operating.

The present embodiment is configured as described above, and its operation will be explained below.

When the ring switch 18 is operated while the receiver is on the hook, a ring tone is sounded in response to the output of the operation signal A, the timer circuit 22 starts measuring time, and the count value of the counter 24 increases. 1”. In this state, when the handset is removed or a timer signal is output after a set time has elapsed, the operations of the timer circuit 22 and counter 24 are stopped and the system returns to its initial state.

On the other hand, when the call switch 18 is operated again within the set time, the timer circuit 22 starts counting again from the initial state, and the count value of the counter 24 becomes "2".
becomes. In this state, if the handset is removed or a timer signal is output, the device enters the initial state as described above.

Then, within the set time, call switch 18
When the counter 24 is operated, the count value of the counter 24 becomes "3", so the detection signal B is outputted, and accordingly, the operation of the audio signal generation circuit 38 is started.
As mentioned above, the voice message "I'm away at the moment" is announced. Further, the timer circuit 22 and counter 24 are reset by a timer signal output after a set time has elapsed, and are brought to an initial state.

(Effect of the invention) As explained above, according to the invention, when the call switch is operated a set number of times within the set operation interval, it is determined that the family member is absent, and a message is automatically sent to notify the user of the absence. Since it is configured to output, it eliminates the trouble of operating the absence switch as in the past, and also eliminates the possibility of conveying incorrect information to visitors.

Note that in this embodiment, a voice output is used as the message, but of course a configuration in which a message such as "I am away at the moment" may be used may also be used.
