DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the electrical construction of the multi-function telephone system of the present invention.

The multifunction telephone system of the present invention is roughly divided into a telephone body 1 connected to a telephone line 4, an intercom body 2 connected to the telephone body 1, and a telephone body 1.
And an electric lock 3 connected to.

A telephone section 11 in the telephone body 1 is connected to the telephone line 4, and the telephone section 11 and the remote operation section 1 are connected.
2 is a bidirectional connection. Further, the output of the remote operation unit 12 is guided to the electric lock operation unit 18.

The telephone section 11 is equipped with a speech network circuit for performing 2-line to 4-line conversion, an incoming call detection circuit, a dial circuit, a holding circuit and the like. The remote control unit 12
This block outputs an unlocking mode signal based on a signal indicating unlocking of the electric lock 3 sent through the telephone line 4.

Further, the doorphone main body 2 is bidirectionally connected to the doorphone circuit 13 built in the telephone main body 1 via a transmitting amplifier 14 and a receiving amplifier 15, and the output of the doorphone main body 2 is: It is connected to the call signal detector 16. The output of the ringing signal detecting unit 16 is connected to the ringing signal measuring unit 17, and the ringing signal measuring unit 1
The output of 7 is led to the electric lock operating unit 18.

The call signal detector 16 is a block for detecting a call signal by operating the call button 21 of the intercom main body 2. The call signal measuring unit 17 includes a call signal detecting unit 16
It measures the continuous arrival time of the ringing signal detected by the measurement, and the measurement time is a predetermined time (this time may be set in advance or may be arbitrarily registered and changed by the user himself / herself). Is a block that outputs a control signal.

Further, the electric lock operating section 18 includes an AND circuit 1
81 and an OR circuit 182. The output of the remote operation unit 12 and the output of the ringing signal measuring unit 17 are guided to the respective inputs of the AND circuit 181.
The output of 1 is led to one input of the OR circuit 182. The output of the electric lock operation button 19 provided on the telephone body 1 is led to the other input of the OR circuit 182, and the output of the OR circuit 182 is led to the electric lock 3. There is.

Next, the unlocking operation of the electric lock 3 in the multi-function telephone system having the above-mentioned configuration will be described when the key is forgotten and the user returns home.

However, the electric lock 3 can be locked and unlocked from inside the house by the electric lock operation button 19 as in the conventional case.

When the user of this multi-function telephone system notices that he / she has forgotten his / her home key when he / she is out, he first makes a call from his / her out-of-place telephone to his / her home telephone and remotely operates to unlock the electric lock. Input a signal indicating a lock. The signal indicating the unlocking is received by the telephone unit 11 through the telephone line 4 and sent to the remote operation unit 12.

In the remote operation section 12, an unlock mode signal (in this embodiment, an H level signal) is output to the electric lock operation section 18 based on the unlock signal input by the user. To do. The unlocking mode signal is stopped by the user operating a release button (not shown) of the telephone body 1 after returning home.

After that, the user of this multi-function telephone system returns to his / her home and performs an operation of continuously pressing the call button 21 of the intercom body 2 installed at the entrance for a predetermined time or longer.
As a result, a call signal is output from the intercom main body 2 to the telephone main body 1 while the call button 21 is continuously pressed, and a ringing tone is output from the speaker (not shown) of the intercom circuit 13. The call signal is detected by the call signal detector 16 and is given to the call signal measuring unit 17.

The ringing signal measuring unit 17 measures the continuous arrival time of the input ringing signal, and when the measured time exceeds a predetermined time (for example, 5 seconds), a control signal is sent to the electric lock operating unit 18. (In this embodiment, it is an H level signal).

The electric lock operating unit 18 is the remote operating unit 12
One input of the AND circuit 181 is kept at the H level by the unlocking mode signal from, and in this state, when the H level control signal is input from the call signal measuring unit 17, the H level appearing at the output is Signal is OR circuit 182
Is output to the electric lock 3 via.

The electric lock 3 unlocks the electric lock 3 based on the H-level unlock signal output from the electric lock operating section 18.

By performing the above operation, the user of this multi-function telephone system can unlock the key even when he / she returns home by forgetting the key and can enter the house.

In the above embodiment, the ringing signal measuring unit 1
Although 7 is configured to measure the continuous arrival time of the input calling signal, it can be configured to measure the number of times the calling signal is detected. That is, when the number of times the call button 21 is pressed within a fixed time (for example, 10 seconds) reaches a predetermined number (for example, 5 times), an H-level control signal is output to the electric lock operation unit 18. It is possible to configure.

Further, in the above embodiment, the remote operation unit 1
The unlocking mode signal output from 2 is configured so that the output is stopped by the user operating the release button (not shown) of the telephone body 1 after returning home. Etc. are built in, and when the timer counts a certain time (for example, 30 minutes after the signal indicating the unlocking of the electric lock is input from the telephone line 4), the output of the unlocking mode signal is stopped and the unlocking mode signal is released. It can be configured to automatically release the lock mode. In this way, even if the user forgets to release the unlocking mode after returning home, the unlocking mode is automatically released after the elapse of a certain time. It is possible to reliably prevent occurrence of an unexpected situation in which the electric lock 3 is unlocked by accident.

[0031]

According to the multi-function telephone system of the present invention, the electric lock operation section is set to the unlock mode by remote operation from the telephone line, and the electric lock operation is performed based on the subsequent call signal from the intercom body. Since the unlocking signal is output from the unit to the electric lock, the user who forgets the key and returns home can enter the doorphone body installed at the entrance after the signal indicating unlocking by telephone from outside the house is input. By performing a predetermined operation of the call button of, there is an effect that even if the key is forgotten, the lock can be opened to enter the house.
