Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home exchange,
In particular, the present invention relates to an in-home switching device that is suitable for home use.

[0002]

2. Description of the Related Art In a conventional private branch exchange in which an intercom and a telephone are connected, in general, ringing tones between an external line (line) and an internal line can be identified as different ringing sounds by a ringer (electric bell device). The ringing sound by
Chime sound such as "ping-pong." However,
With the method of varying the ringing sound by the ringer, no matter how much the ringer is made to ring, it may not be easy to distinguish, especially when there is noise in the surroundings, and there is a possibility that it may be heard differently. It has the drawback of being bad. On the other hand, due to the spread of two-family houses, there are more cases where two external lines are laid, and in addition, two-family houses have two entrances and doorphones installed in each house. The number of types of sources has increased, and it is no longer possible to distinguish the source by ringing noise or chime sound.

In order to improve such a situation, for example, as described in Japanese Patent Application No. 4-320117, there has been proposed a private branch exchange in which the type of incoming call can be identified by a voice message. With this private branch exchange, when an incoming call arrives, for example, "I have a call to the outside line" 1 "" and "I have a customer to the intercom" 2 "".
I will send out a voice message.

[0004]

By the way, Japanese Patent Application No. 4-
In the private branch exchange described in No. 312117, it is possible to determine the type of the transmission source by sending different voice messages depending on the incoming call before off-hook, but since the voice messages are the same or confusing, There is a high possibility that the response content is misunderstood. For example, in a two-family house, etc., even if a voice message saying “I am a customer on the doorphone” is issued, it is not possible to know at which door the visitor appeared from the voice message alone. On the other hand, the message content is different between "I am calling on the outside line" 1 "" and "I am calling on the outside line" 2 "", but the only difference is "1" and "
2 "only, for example, while watching TV,
There is a possibility of misunderstanding "1" and "2." If such a misunderstanding occurs with a voice message regarding security information, for example, even if the bathroom is on fire,
It is a big deal if you misidentify the kitchen as a fire.

The present invention has been made in view of the above circumstances. Even if the contents of a voice message cannot be accurately heard due to noise in the surroundings, it is possible to accurately determine where the incoming call came from. Is intended to provide.

In order to solve the above-mentioned problems, the invention according to claim 1 is a private branch exchange capable of connecting at least a plurality of communication devices and an alarm device, and a plurality of confusing arbitrary transmission sources. For each of the above sources,

According to a second aspect of the present invention, there is provided a home exchange capable of connecting a plurality of outside lines, wherein a storage unit for storing a voice message for notifying an incoming call with a different voice quality for each outside line, and an outside line incoming call. It is characterized in that it comprises a control unit for reading out a voice message corresponding to the received outside line from the storage unit, and a sounding means for producing the voice message read by the control unit.

The invention according to claim 3 is a home exchange capable of connecting a plurality of intercom slaves, and a storage section for storing a voice message for notifying an incoming call with different voice quality for each intercom slave. , A control unit for reading a voice message corresponding to an incoming intercom slave unit from the storage unit when an intercom is received, and a sounding unit for producing a voice message read by the control unit. .

Furthermore, the invention according to claim 4 is a home telephone exchange to which a plurality of security annunciators can be connected, and a storage unit for storing a voice message for issuing a warning with a different voice quality for each security annunciator. And a control unit for reading out a voice message corresponding to a security alarm device for issuing an alarm in the event of an emergency from the storage unit, and a sounding unit for producing the voice message read by the control unit. I am trying.

[0009]

According to the structure of the present invention, an incoming call or situation is notified to a plurality of confusing sources by voice messages having different voice qualities (for example, male voice and female voice) for each source. It Therefore, the incoming line "1" or the external line "
It is possible to determine whether the incoming call is 2 ", the incoming call is from the intercom slave" 1 ", or the incoming call is from the intercom slave" 2 ".

Next, the operation of the above configuration will be described with reference to FIGS. External call incoming First, the operation when an external call is received will be described with reference to FIG. When an incoming call arrives at the outside line TT1 or TT2, the station line circuit 1 (or 2) corresponding to the incoming outside line detects the incoming call and sends the incoming call signals S1 and S2 to the microprocessor 14.
In the following description, it is assumed that the call arrives at the outside line TT1.

In accordance with the incoming signal S1, the microprocessor 14 causes the communication path 6 and the relay control section 7 described below.
To control. The relay control unit 7 directly connects the incoming external line TT1 to a predetermined slave unit 12 (or 13), and causes the connected slave unit to ring a ringing tone. However, since the slave unit is directly connected to an outside line, the number of connected units is determined by the technical standard of terminal equipment (the number of ringing slave units is limited, and this is called ringing-designating slave unit). For example, handset 1
When 2 is set as the ringing designation slave, the switch SW1 is switched to the terminal T11 side, and the switch SW2 is switched to the terminal T21 side to which the incoming external line TT1 is connected.

On the other hand, when the slave unit 13 is set as the ringing-designated slave unit, the switch SW3 is switched to the terminal T31 side and the switch SW4 is switched to the terminal T41 side to which the incoming external line TT1 is connected. Good. As a result, as shown in FIG. 2, during the period 1S during which the incoming signal is supplied from the outside line TT1, the slave unit 12 which is the ringing-designated slave unit directly connected to the outside line TT1 receives an incoming call such as "Torurururu". Make a sound.

On the other hand, after the incoming call is detected, the microprocessor 14 controls the communication path 6 to make the next connection. That is, in the communication path 6, a slave device other than the ringing-designated slave device, in this case, the slave device 13 is connected.
The PMJ11 creates a line for sounding the ring tone, and a voice message for notifying the incoming call is sent.
A line for making a sound from PMJ11 is created.

Under the control of the microprocessor 14, a ring tone such as "Torururu" is read from the voice output unit 5 and output to the input / output terminal IN-OUT4 via the above line of the communication path 6. To be done. This ring tone is supplied to the SPMJ 11 to which the child device 13 is connected via the extension circuit 9. Then, in synchronization with the ringing of the cordless handset 12 which is the ringing-designated cordless handset, the ring tone of "Torururu-" is emitted from the speaker of the SPMJ 11.

Next, under the control of the microprocessor 14, a predetermined voice message (for example, "calling to the outside line" 1 "with a female voice") is transmitted by the voice output unit 5 to the communication path 6.
Is output to the input / output terminal IN-OUT4 via the above line. This voice message is sent via the extension circuit 9 to the S
It is supplied to PMJ11. Then, the voice message is sounded from the speaker of the SPMJ 11. As a result,
As shown in FIG. 2, in the period 1S, the SMPJ to which the slave device other than the ringing-designated slave device, in this case, the slave device 13 is connected.
The ring tone is sounded by 11, and in the period 2S immediately after the ring tone is pronounced, the SPMJ11 connected to the child machine 13 produces a voice message "Calling the outside line" 1 "" in a female voice. To be done.

When the extension circuit 8 detects the off-hook of the child device 12 directly connected to the outside line TT1,
The extension circuit 8 sends the off-hook signal to the microprocessor 1
Send to 3. Upon receipt of the off-hook signal, the microprocessor 14 stops the ringing tone and the voice message from the voice output unit 5 and puts the handset 12 in a state where an outside line call is possible. When the slave 13 other than the ringing-designated slave is off-hook, the microprocessor 14 stops the ring tone and the voice message, and then switches the switch SW3 of the relay controller 7 to the terminal T31 side (external line TT1). Side), the switch SW4 is switched to the terminal T41 side, the handset 13 is connected to the outside line TT1, the outside line communication is enabled, and the switches SW1 and SW2 are turned over to make the handset 12.
Is disconnected from the outside line TT1.

When the outside line TT2 is received in the above-described operation upon receiving an outside line, the voice quality of the voice message pronounced by the SPMJ11 is set to a male voice. As a result, even if it is difficult to hear the content of the voice message, it is possible to instantly determine whether the incoming call is the external line TT1 or the external line TT2.

Next, the operation upon receipt of the intercom will be described with reference to FIG. When a visitor presses the push button of the intercom slave unit 3, the intercom control unit 4 detects an intercom incoming call and sends an intercom incoming signal to the microprocessor 14.

The microprocessor 14 controls the communication path 6 and the relay control section 7 in accordance with the intercom incoming signal as described below. In the relay control unit 7, the chime sound stored in the voice output unit 5 is sent to the SPM.
Switch SW2 for ringing by J9, 10
Is switched to the terminal T22 side, and the switch SW4 is switched to the terminal T42 side so that the cordless handsets 12 and 13 are connected to the communication path 6.
Connect to. In the communication path 6, a line for making the chime sound of the voice output unit 5 ring by the intercom slave 3 and the SPMJs 10, 11 is created, and a voice message for notifying an incoming call is sent to the SPMJs 10, 11. Create a line.

Next, a chime sound such as "ping-pong" is read from the voice output section 5 by the control signal output from the microprocessor 14, and the intercom slave 3 and the SPMJ1 are read.
It is sent to 0 and 11. As a result, as shown in FIG.
In the intercom slave unit 3, a chime sound such as "ping-pong" is emitted (callback), and at the same time, the SPMJ
Also in 10 and 11, a chime sound such as "ping-pong" is sounded. Furthermore, the microprocessor 14 activates the voice output unit 5, and "I am a customer for the intercom" 1 "."
And the like are sent to the SPMJs 10 and 11. As a result, in SPMJ10 and 11, following the above chime sound, "I am a customer at the doorphone" 1 "."
Etc. voice message is pronounced.

When the slave unit 12 (or 13) is hooked off, the extension circuit 8 (or 9) causes the slave unit 12 (or 13) to go off-hook.
Off-hook (or 13) is detected and an off-hook signal is sent to the microprocessor 14. Upon receiving the off-hook signal, the microprocessor 14 stops the chime sound and the voice message, and connects the off-hook slave 12 (or 13) and the intercom slave 3 to the communication path 11
, And the intercom communication is enabled.

In the above-mentioned operation when the intercom is received,
When two intercom slaves are installed, for example, when an incoming call is received by each intercom slave, for example, when an intercom "1" is received, a female voice calls the "intercom" 1 ". It's a phone call. "
When an incoming call arrives at the doorphone "2", a male voice will send out a voice message saying "I am a customer at the doorphone" 2 "", even if I miss the contents of the voice message. It is possible to instantly determine whether the incoming call is from a doorphone handset.

Security Alert Next, with reference to FIG. 4, an operation at the time of a security alert will be described. When an emergency such as a fire is detected by a predetermined sensor, in this case the fire sensor, the security device 15 sends a detection signal to the microprocessor 14. The microprocessor 14 performs the following communication path control according to the sensing signal. In the communication path 6, a line for producing a security warning sound such as "Peepo" from the SPMJs 10 and 11 is created, and
Create a line to send out a voice message in the event of an emergency such as "fire, please check".

Then, the microprocessor 14 repeats from the voice output section 5 a security warning sound such as "Peepo" and a voice message such as "fire occurrence, please confirm" consisting of a male voice, and SPMJ10,1.
Send to 1. As a result, as shown in FIG.
The security alarm sound and the voice message are repeatedly pronounced by each of the PMJs 10 and 11. Then, when the sensing signal from the security device 15 is turned off, the microprocessor 14 stops the sounding of the security alarm sound and the voice message.

When an emergency situation other than a fire is discovered and the emergency button is operated, the security device 15
Sends a press signal to the microprocessor 14. The microprocessor 14 performs the following communication path control according to the push signal.

In the communication path 6, SPMJs 10 and 11
Create a line for sounding a security alarm sound such as "Pipopara" and a line for sending a voice message in an emergency such as "emergency situation, please check".

Then, the microprocessor 14 outputs from the voice output section 5 a security alarm sound such as "Pipopara" and a voice message such as "Emergency occurrence, please confirm" composed of a female voice to the intercom call effective time. Within, for example, once or several times within 30 seconds, S
It is sent to the PMJs 10 and 11. As a result, as shown in FIG. 4B, the SPMJs 10 and 11 repeatedly generate the security alarm sound and the voice message.
It should be noted that even if another doorphone is pressed during this period, it is ignored, and becomes valid when the above period ends (see pressing other doorphone in the figure). Then, when the sensing signal from the security device 15 is turned off, the microprocessor 14 stops the sounding of the security alarm sound and the voice message.

When a plurality of sensors are installed or a plurality of abnormalities (fire, gas leak) are detected in the above-mentioned operation at the time of the security alarm, a man, With different voice qualities such as women, even if the voice message content is difficult to hear,

Next, the operation of the private branch exchange system of this example will be described. Since the basic operation of this private branch exchange system is the same as the operation of the configuration shown in FIG. 1, there are differences in the structure of this private branch exchange system, that is, two external lines (7 cordless handsets), one intercom line ( The operation caused by the fact that it is four slaves will be described in particular.

External line incoming call (1) When the remote unit has no incoming call restriction setting When the external lines TT1 and TT2 are received at the same time, the microprocessor 14 causes the external line incoming tone sending section 5b of the voice output section 5 to be received.
The ring tone and voice message of the external line TT1 read from the external line TT1 are sent to the SPMJ 32 to which the dedicated slave units 33, 33, general slave units T3 to T5, and the facsimiles F1 and F2 are connected via the communication path 6. When the slave unit responds to this, the ring tone and voice message of the outside line TT1 are stopped, and the ring tone and voice message of the outside line TT2 are transmitted to the dedicated slave units 33 and 33, the slave units T3 to T5, and the facsimiles F1 and F2.
To SPMJ32. However, the voice message for the outside line TT1 is a female voice, and the voice message for the outside line TT2 is a male voice.

(2) When the mobile phone is set to receive incoming call restriction The ring tone and the voice message are not transmitted to the external line for which incoming incoming call restriction is set (the remote terminal does not ring), and the external line is not set to receive incoming call restriction. As for the ring tone and the voice message, the dedicated slave units 33 and 33, the slave units T3 to T5, and the SPMJ3 of the facsimiles F1 and F2, as in the configuration shown in FIG.
Send to 2.

When an incoming call is received from a doorphone slave unit D1 to D4 by a visitor, the incoming call restriction operation is the same as the above-mentioned external line incoming operation. However, the call can be made even if the incoming call restriction slave is off-hook.

As shown in FIG. 3, when an intercom arrives at the intercom, the other intercom call is available within the valid intercom time (the available time of the intercom slave to which the off-hook chime sound and voice message are supplied, for example, 30 seconds). Even if the intercom is pressed, the ringtone and voice message of the intercom that is pressed later are not transmitted. If the doorphone call valid time is exceeded, normal operation is performed.

The chime sound of the intercom read by the microprocessor 14 from the intercom ring tone section 5c of the voice output section 5 is transmitted via the communication path 6 to the intercom slave units D1 to D1.
Both D4 and SPMJ32 are sent, but the subsequent voice message is sent only to each SPMJ32 by each route select switch 37 shown in FIG. However, the voice message to the intercom slaves D1 and D3 is a female voice, and the voice message to the intercom slaves D2 and D4 is a male voice.

◇ Security alarm When the security device (flame sensor, gas sensor, emergency alarm) 15 senses an emergency, the SPMs of the dedicated slave units 33, 33 and the slave units T3 to T5 are similarly to the configuration shown in FIG.
Send a voice message to J32. However, when an emergency is detected by the flame sensor 1, a female voice is output, and when an emergency is detected by the flame sensor 2, a male voice is output. Similarly, the gas sensor and the emergency alarm are output with different voice qualities.

As described above, the voice output unit (including intercom and chime sound transmission) 5 is provided in the home exchange, and the microprocessor 14 controls the voice output unit 5 so that the SPMJ 32 transmits a voice message having a different voice quality according to the situation. Make it sound. Therefore, the type of incoming call can be instantly determined before going off-hook.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, in the above-described embodiment, when an incoming call is received on the outside line "1", a voice message "Calling the outside line" 1 "" is transmitted by a female voice, while the outside line "2" is sent. When there is an incoming call,
I mentioned the case where a voice message saying "I'm calling on the outside line" 2 "" is sent out by a male voice, but instead of this,
When there is an incoming call on the outside line "1", a female voice will send out a voice message saying "I am calling the outside line."
On the other hand, when an incoming call is received on the outside line "2", the same effect as described above can be obtained even if the voice message "Call the outside line" is sent by the male voice.

Similarly, in the above embodiment, when an incoming call is received from the intercom slave "1", a voice message "You are the customer at the intercom" 1 "" is sent out by a female voice, On the other hand, when there is an incoming call from the intercom slave "2", a male voice says "I am a customer at the intercom slave" 2 "."
However, instead of this, when there is an incoming call from the intercom slave "1", a female voice message "You are the customer" is sent out. On the other hand, when an incoming call is received from the intercom slave "2", the same effect as above can be obtained even if the voice message "I am a customer" is sent out by a male voice. You can In addition, if there is a fire in the kitchen, a female voice will send out a voice message saying "Fire is occurring", while if there is a fire in the bathroom, a male voice will say "Fire is occurring". Even if a voice message is sent, the same effect as above can be obtained. Here, not only the male voice quality and the female voice quality but also the voice quality of the child and the voice quality of the adult may be used for discrimination. In this way, four types of voice qualities, male adult, male child, female adult, and female child, can be used, which makes it easy to identify the four types of sources. Of course, the types of voice qualities may be further increased if necessary.

[0055]

As described above, according to the configuration of the present invention, an incoming call or situation is notified to a plurality of confusing transmission sources by voice messages having different voice qualities for each transmission source. Even in a situation where it is difficult to hear the content of the message without listening quietly, the content of the notification (where the call came from) can be easily and reliably recognized.
