Description

  The present invention relates to an intercom system for a visitor to call a resident by calling.

  In the intercom system where a conventional visitor calls a resident and enables a call, when the slave unit installed at the entrance is called and operated, the ringing tone is immediately sounded at the master unit installed in the room, so the visitor Residents could be called regardless of the purpose of the visit. Therefore, by responding, the resident understood the purpose of the visitor and refused to meet in some cases. Therefore, even the vicious door-to-door sales were responsive, and the response operation was carried out even if the call operation was performed by mischief.

Since the response to the call of the visitor who wants to refuse is bothersome, an intercom system has been proposed which is devised to eliminate the unnecessary response. For example, according to Patent Document 1, when a call is received, a message to hear a request from a handset is first sounded, and the resident should respond by receiving the message and reproducing the voice of the visitor recorded on the base unit. I was able to determine if I was there and eliminated unnecessary response operations.
Further, in the cited reference 2, the speech recognition unit is provided, and if the speech of the visitor includes a keyword, the word is notified to the resident to draw attention.

  However, it is a resident who determines whether to respond or not, the configuration of Patent Document 1 involves an operation of reproducing and listening to the voice of the recorded visitor, and annoyance continues to occur. Moreover, in the cited reference 2, since the resident receives a voice calling with a visitor and warns, the resident is in the middle of responding, and the response itself is not lost.

  Therefore, in view of such problems, the present invention does not immediately ring the ringing tone from the base unit when the visitor makes a call operation, and judges whether the resident can be called or not based on the business condition, and the call is permitted. It aims at providing the intercom system which carries out a resident's call only when it judges.

In order to solve the above problems, the invention according to claim 1 is an intercom having a slave unit for a visitor to call a resident and make a call, and a master unit for a resident to respond to a call from the slave unit. The system includes a call determination control unit that determines whether a ringing tone is to be sounded from a master unit in response to a call operation of a slave unit, and a message storage unit that stores a message to be sounded from a slave unit. The call determination control unit has a voice recognition function that recognizes a word from the voice of the visitor, and when the handset receives a call operation, the handset makes a notification sounding a message from the handset, and It is characterized in that it recognizes the wording of the visitor's voice picked up by the machine, and judges from the wording of the visitor's speech whether or not to ring the ringing tone from the parent machine.
According to this configuration, even when a call is received, the ringing tone is not immediately sounded by the base unit, and first, an announcement to hear the matter from the child unit is notified, and then whether the resident call can be made from the voice emitted by the visitor Therefore, when it is determined that the call can not be made, the call itself is not performed. For example, if it is judged whether or not a word including a pre-registered rejection language is spoken, the resident's call is carried out only when the word that describes the matter does not contain the rejection language. Therefore, since the calling determined as not being able to be called does not ring the ringing tone from the base unit, the resident does not need to know that the calling operation has been performed, and it is necessary to confirm the visiting person and refuse to meet in some cases or stay away. There is no need to use and stress can be reduced.

In the second aspect of the present invention, in the configuration according to the first aspect, after the call determination control unit has sounded a message for asking about a subject, if there is no sound collection of voice that can be confirmed within a predetermined time, the parent It is characterized in that the handset unit does not sound a ringing tone, and a handset unit sounds a message indicating that the resident will not be called.
According to this configuration, after the notification message is sounded, the resident is not called if the child device does not pick up a sound that can be confirmed, that is, if there is no response from the visitor. Therefore, it is effective because a call is not made to a mischief which does not carry out an unnecessary call, and in particular disappears immediately after the call operation. Also, the visitor who recognizes that the call is not made despite the fact that he / she described the matter can know that the matter has not been received, and can take the next action such as making another call.

The invention of claim 3 according to claim 1 has a language storage unit storing a rejection language for determining whether to permit or reject a call, and the call determination control unit generates a notification sounding a message covering a matter. If it detects the refusal language stored in the language storage unit from the wording of the visitor's voice after making it do, the resident will not be called and the message to the effect that the calling will not be made will be sounded from the handset I assume.
According to this configuration, since the judgment is made based on the presence or absence of the pre-registered rejection language, it is possible to judge whether or not the resident call can be made by simple judgment control. Then, when the call is rejected, the visitor is notified of the fact, so that the visitor can be made aware that the response is refused, and the resident can leave it without any operation.

The invention according to claim 4 is characterized in that, in the configuration according to claim 3, the parent machine has a rejection language setting unit, and the rejection language can be set by the resident.
According to this configuration, the rejection language can be set in accordance with the preferences and convenience of the resident, and the convenience is good.

According to the invention of claim 5, in the configuration according to claim 3 or 4, an electric lock that is unlocked / locked by the parent machine is installed on the entrance door where the child machine is installed, and the call judgment control is performed. When the electric unit is notified of the ringing tone from the base unit and the electric lock is not unlocked despite the response operation, the main word in the message issued by the visitor is rejected It is characterized by additionally storing in a language storage unit.
According to this configuration, since the rejection language is added with the learning function, the judgment system is improved.

The invention according to claim 6 is the configuration according to any one of claims 3 to 5, wherein the child machine comprises a camera for imaging a visitor, and a visitor identification unit for specifying a person from an imaged video, imaging of the camera The specific image storage unit stores the captured image of the visitor determined to be a call rejection among the images, and the call determination control unit is configured to store the visitor image captured by the camera in the specific image storage unit If it is determined that the message is the same as the stored person, the message that the call is not made is notified from the child device without giving a notification message from the child device.
According to this configuration, when a person who refuses the call once appears again, it can be quickly eliminated by notifying that the call will not be made without asking for business.

According to the invention of claim 7, in the configuration according to claim 6, date and time information and a rejection language issued by a visitor are stored in the specific video storage unit in association with the video, and the call determination control unit If the person who judged the call rejection appears again and performs the call operation, in addition to the notification sound of the message not to call, notification of the last visit date and time and the rejection language issued by the visitor from the handset It features.
According to this configuration, it is possible to convince the visitor and prevent the revisiting, because the slave unit notifies the reason for not making a call without asking for a business condition.

In the invention of claim 8, in the configuration according to any one of claims 1 to 7, the master unit has a function of communicating with an external server via a communication network, and the call determination control unit is disposed in the server. It is characterized by
According to this configuration, an increase in the cost of the intercom device can be suppressed by externally providing a call determination control unit requiring a high function.

  According to the present invention, even when a call is received, the ringing tone is not immediately sounded by the master unit, and first, an announcement to hear the matter from the handset is sounded, and whether the resident call can be made from the voice emitted by the visitor thereafter Therefore, when it is determined that the call can not be made, the call itself is not performed. For example, if it is judged whether or not a word including a pre-registered rejection language is spoken, the resident's call is carried out only when the word that describes the matter does not contain the rejection language. Therefore, since the calling determined as not being able to be called does not ring the ringing tone from the base unit, the resident does not need to know that the calling operation has been performed, and it is necessary to confirm the visiting person and refuse to meet in some cases or stay away. There is no need to use and stress can be reduced.

  Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an example of an intercom system according to the present invention, and shows individual devices in a block diagram. The intercom system is comprised of a handset 1 installed at an entrance or the like for a visitor to call a resident, and a master 2 installed in a dwelling unit for a resident to respond to a call from the handset 1 And both are connected by the transmission line L1.

  The handset 1 processes the video signal captured by the handset camera 13 and the handset camera 13 for capturing a visitor, the handset call unit 12 having the call button 11, the handset microphone 12a and the handset speaker 12b. A slave unit video processing unit 14, a slave unit CPU 15 for controlling the slave unit 1, and a slave unit communication IF 16 for communicating with the master unit 2 are provided.

The base unit 2 includes a base unit operation unit 21 for performing a response operation to the call and various settings, a base unit microphone 22a for making a call, and a base unit call unit 22 having a base unit speaker 22b, A message storage unit 23 for storing a message, a call determination control unit 24 for determining whether or not to notify the resident upon receiving a call from the handset 1, a visitor identification unit 25 for identifying a visitor from a captured image of the handset camera 13, A video storage unit 26 for storing a visitor video, a display unit 27 for displaying a visitor video and various information, a base CPU 28 for controlling the base unit 2, and a base unit communication IF 29 for communicating with the base unit 1 are provided.
The call determination control unit 24 includes a speech recognition unit 24 a that recognizes a language from speech and a language storage unit 24 b that stores a specific language.
Furthermore, the master unit 2 is connected to the electric lock 3 provided on the entrance door (not shown) of the entrance provided with the electric lock control unit 30 and the slave unit 1 via the transmission line L2. The unlocking / locking of the electric lock 3 is made possible by the operation of the main unit 2.

The operation of the intercom system configured in this way is as follows. In the present invention, in addition to the function of judging whether or not to call from the word issued by the visitor, the function to judge whether or not to call from the image of the visitor is provided. First, the flow of judging from the word of the visitor will be described. Do.
When the handset 1 is operated by a visitor and a call is made, a call signal is transmitted to the base unit 2, and in the base unit 2 that receives the call signal, the call determination control unit 24 carries out the following control. . First, the handset 1 informs the visitor of a predetermined message confirming the event. For example, the words "please talk about your business" are selected from the message storage unit 23 and sounded.
At this stage, the base unit 2 does not sound a ringing tone, and control for calling a resident is not performed.

  A message notifying that the resident will not be called if the visitor does not issue a message or can not recognize a voice within a certain period of time (for example, 30 seconds) after announcing a message to cover the message Sound from handset 1. For example, a message “I can not call you because I could not answer the message” is selected from the message storage unit 23 and is sounded.

Also, even if the visitor stated the matter within a certain period of time, if the prescribed matter (rejected language) is included in the stated matter, the resident should not be called again. To notify. When the speech recognition unit 24a of the call determination control unit 24 analyzes the wording of the matter described by the visitor and recognizes that, for example, the word "repair, newspaper, religion, etc." is included as the rejection language, the call control is performed. Do not
In that case, according to the detected wording, for example, if the wording of “newspaper” in the rejection language is included, “don't call for invitation of newspaper” is notified from the handset 1. The denial language is set in advance by the resident operating the base unit operation unit 21 and stored in the language storage unit 24b.

  On the other hand, if the visitor stated a matter such as "It is ○ ○. It is a circular board," it is judged that there is no rejection language in this wording, and the ringing tone is sounded at the main unit 2 and the resident Informing that there is a visitor in Then, for example, when a message “I'm calling” is notified from the handset 1 and then the base unit 2 is operated in response, a communication path is formed between the handset 1 and the base unit 2.

  Furthermore, the call judgment control unit 24 has a learning function, and the electric lock 3 on the front door is not unlocked even though the resident responds by receiving the ringing tone of the base unit 2 Then, it is judged that the visitor wants to refuse the response, and the main wording is judged from the wording of the matter described by the visitor and additionally registered in the language storage unit 24b as a rejection language, and the judgment as to whether or not to call later Applies to

As described above, even when a call is received, the ringing tone is not reported by the base unit 2 immediately, and an announcement is made from the base unit 1 to hear the matter. After this announcement, the voice is collected from the base unit microphone 12a. If not, i.e., there is no response from the visitor, and if you speak a word that contains a pre-registered rejection language in the stated matter, the call will not be made. Then, if it is determined that there is no rejection language in the request issued by the visitor, then the resident is called and control is performed to notify the resident that there is a visitor from the base unit 2.
Therefore, since a call from a visitor who is determined not to be called is not notified in the base unit 2 by a call, the resident does not need to confirm the visitor one by one and may not be away in some cases, thereby reducing stress. In addition, after the announcement to cover the matter is made, the resident is not called up without the response from the visitor, so it is effective because the call is not made correspondingly to the mischief which leaves immediately after the call operation. It is.
In addition, it is possible to judge whether or not the resident call can be made by simple judgment control to judge based on the presence or absence of the pre-registered rejection language, and when the call is rejected, the visitor is notified of that, so the visitor is notified It can be made to recognize that it is denied, and it can be made to leave without operation by the resident.
In addition, since the rejection language can be set according to the preference of the resident, the resident can select the visitor who wants to refuse the response, which is convenient.
In addition, the decision system is improved because it has a learning function and additional rejection languages are accumulated.

  Next, a flow of judging whether or not to call can be determined from the image captured by the slave camera 13 will be described. The image storage unit 26 stores the visitor image captured by the slave camera 13 together with the date and time information of the visit, each time the call is made under the control of the master CPU 28. Then, among the stored images, the image of the visitor who refused the calling of the resident is specified by the control of the call determination control unit 24 such that the refusal language that is the reason for the determination is linked and the identification in the image storage unit 26 It is stored in the video storage unit 26a.

Based on the video information stored in this manner, the visitor identification unit 25 compares the visitor video that has been called and captured by the handset camera 13 with the person registered in the specific video storage unit 26a, If it is determined that the visitor is a person stored in the specific video storage unit 26a, the call determination control unit 24 receives the information, and the visitor can not call the base unit 2 without asking for a business request. Notify
Concretely, for the visitor who matched the visitor of the past, read the visit date and time stored with the image and the rejection language in the remark, and can not call the base unit 2 with the reason for calling rejection Notify me of the message. For example, a message of "The customer visited my company on the day of xx month x xx, but the matter was a solicitation for a newspaper, and I will not call it this time." Is notified from handset 1.
Here, the determination is made based on the video information captured by the slave camera 13, but it is needless to say that the determination may be made based on the image information.

By doing this, a person who once refused the call can be quickly dismissed by notifying that the call is not made without asking for the business.
In addition, since the handset 1 notifies the reason for not making a call, the visitor can be convinced to prevent another visit again.

  In the above-described embodiment, the call determination control unit 24 is provided in the master 2 but may be provided in the slave 1 or outside. FIG. 2 shows a configuration in which the parent server 2 can communicate with the cloud server 4 installed in an external security company or the like via the communication network N and the Internet and the call determination control unit 24 is provided to the cloud server 4. . Furthermore, at that time, the visitor identification unit 25 may also shift to the cloud server 4, and an increase in the cost of the intercom device can be suppressed by collectively providing a control unit requiring a high function outside. In addition, it is easy to take measures against suspicious persons, and security can be improved.

  In addition, although the slave 1 and the master 2 are connected by the transmission line L1, communication of the both may be performed wirelessly. Furthermore, as shown in FIG. 3, both may have a function of connecting to the communication network N so as to be able to communicate with the cloud server 4. By doing this, it is also possible to make the base unit 2 a portable terminal 5 such as a smartphone, and there is no need for a dedicated base unit. In this case, the video storage unit 26 and the message storage unit 23 may be provided in the cloud server 4 in addition to the call determination control unit 24 and the visitor identification unit 25, and an application for the portable terminal 5 to communicate with the cloud server 4 Only by installing the software, it is possible to provide the same function as the above-mentioned base unit 2.
