In the conventional system, an interphone slave unit operated by a visitor and a plurality of interphone master units (personal computers) arranged in a room are connected via a network, and the name of the visitor is the interphone slave unit. Is input, the visitor's intercom master is called. In the interphone master unit of the called visitor, a ringing tone is generated and a call screen is displayed. (See, for example, Patent Document 1).
In another conventional system, the face of a visitor who performs a call operation is photographed in order to reduce the trouble of dealing with unnecessary calls when the resident is working at home, etc. A feature part is extracted from the image and personal identification is performed based on the feature part, and a call is notified only when a registered visitor performs a call operation (see, for example, Patent Document 2). ).

Japanese Patent No. 3649725 JP 2002-64641 A

In the conventional system as described above, only the interphone master unit of the visitor is called, so when the person is out of the seat, or when the power source of the interphone master unit is turned off, etc. Inconvenient and sometimes not possible. Calling each interphone master unit other than the visitor's interphone master unit can respond to the visitor's call even if the visitor is out of his / her seat. Users other than visitors may respond to calls unnecessarily.
In addition, in another conventional system as described above, even if a visitor who should be responding performs a call operation, if the face cannot be photographed normally, the call is not notified and the call of the visitor cannot be handled. There's a problem.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an interphone system that can handle calls more reliably while reducing the trouble of handling unnecessary calls. It is.

The intercom system according to the present invention is provided on a network and has memory means for storing personal information including identification information for identifying a user, and is provided in an interphone slave unit. Personal information is input by the user. Personal information input means, a call control means provided on the network for transmitting a call signal to each interphone master unit, and provided for each interphone master unit, respectively, in response to a call signal from the call control means A master unit control unit for informing the call by the notification unit, and calling at least one of the personal information stored in the memory unit and the personal information input by the personal information input unit to call a specific interphone master unit The priority callee information is further included, and the call control means includes the identification information of the personal information input by the personal information input means. Is stored in the memory means, after the call signal is preferentially transmitted to a specific interphone master unit based on the priority call destination information of the personal information, In the case of a response, the intercom system transmits a call signal to each of the other interphone master units. The intercom system further includes photographing means for photographing a user who performs a call operation on the interphone slave unit. Information indicating the characteristics of the face of the user and used to determine the presence or absence of a person's face, and non-detectable callee information for calling a specific interphone master unit are further stored. The means is based on the face reference information of the memory means whether or not a human face can be detected from the image taken by the photographing means when the user performs a call operation with the intercom slave. If it is determined that a human face can be detected, a call signal is transmitted to a predetermined interphone master unit based on a call operation performed by the user using the interphone slave unit, and the human face cannot be detected. When the determination is made, the call operation performed by the user is invalidated, and a call signal is transmitted to a specific interphone master unit based on call destination information when the memory means cannot be detected.

  According to the intercom system of the present invention, when the personal information including the identification information that matches the identification information of the personal information input by the personal information input means is stored in the memory means, the call control means Based on the priority call destination information, when a call signal is preferentially transmitted to a specific interphone master unit and no answer is made, a call signal is transmitted to each other interphone master unit. Visitors can preferentially respond to calls and others can respond to calls even when the visitor is out of the seat. That is, it is possible to deal with calls more reliably while reducing the trouble of handling unnecessary calls.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an intercom system according to Embodiment 1 of the present invention. FIG. 2 is an explanatory diagram showing a management table of information stored in the main part of FIG. In the figure, an interphone slave unit (hereinafter referred to as a slave unit) 1 operated by a visitor has a plurality of interphone master units (hereinafter referred to as a master unit) operated by a visitor via a transmission line 2. 3) and the registration information server 4 are connected. That is, the slave unit 1 is connected to a plurality of master units 3 and the registration information server 4 via a network. The subunit | mobile_unit 1 calls the main | base station 3 designated by the visitor. When the visitor performs a response operation, a call can be made between the child device 1 and the parent device 3. As will be described in detail later, each parent device 3 is managed by being divided into a plurality of groups. The registration information server 4 stores a management table of identification information shown in FIG. The first column of the management table of identification information indicates each visitor individual, and the second column indicates identification information for identifying each individual.

  Next, FIG. 3 is a block diagram showing the slave unit 1 and the master unit 3 of FIG. 1 in more detail. 4 to 6 are explanatory diagrams showing a management table of information stored in the slave unit 1. In FIG. 3, the slave unit 1 includes a slave unit memory unit 10, a slave unit control unit 11, a display unit 12, a group name input unit 13, a photographing unit 14, a personal information input unit 15, a slave unit. An interface 16 is provided. The child device memory means 10 includes a group information storage unit 10a, a personal setting information storage unit 10b, and a priority call destination information storage unit 10c.

  Here, in order to describe this embodiment more specifically, it is assumed that the interphone system is provided with six master units 3 (hereinafter referred to as first to sixth master units), Suppose that -6 master devices are divided into first to fourth groups and managed.

  The group information storage unit 10a stores a group information management table shown in FIG. The first column of the group information management table indicates the group name of each group, and the second and subsequent columns indicate the parent device 3 belonging to each group (specifically, the extension number or IP address of each parent device 3). ). The second and subsequent columns show the call priority of each parent device 3 in each group. The call priority indicates that, for example, when the first group is called, the first parent device is called preferentially. That is, the group information stored in the group information storage unit 10a includes the belonging information indicating the parent device 3 belonging to each group and the intra-group priority indicating the calling priority of each parent device 3 in each group. Information and included.

  As the display means 12, for example, a liquid crystal display or the like is used. As the group name input means 13, for example, a touch panel attached on a liquid crystal display is used. The subunit | mobile_unit control means 11 displays each group name on the display means 12 based on the group information stored in the group information storage part 10a. The group name input means 13 is for the visitor to input the group name displayed on the display means 12 to the child device control means 11.

  For example, a digital camera or the like is used as the photographing unit 14. When the group name is input by the group name input unit 13, the slave unit control unit 11 uses the image capturing unit 14 to image the user who inputs the group name by the group name input unit 13. In other words, when the group name is input by the group name input unit 13, the slave unit control unit 11 uses the photographing unit 14 to acquire an image of the operation status of the group name input unit 13.

  As the personal information input means 15, a card reader device that reads personal information stored in an IC card (information storage device) 21 carried by a visitor and inputs the personal information to the handset control means 11 is used. The personal information stored in the visitor's IC card 21 stores the identification information shown in FIG. When the group name is input by the group name input unit 13, the slave unit control unit 11 causes the display unit 12 to display guidance that prompts the personal information input unit 15 to input personal information. In addition, the slave unit control unit 11 determines whether or not the personal information is input within a predetermined time when the display unit 12 displays the guidance prompting the user to input the personal information.

  When it is determined that the personal information has not been input within a predetermined time, the handset control unit 11 determines the image information and the call signal based on the intra-group priority information corresponding to the group name input by the group name input unit 13. Is transmitted to the parent device 3 of the group via the child device interface 16.

  Further, when it is determined that personal information has been input within a predetermined time, the slave unit control means 11 refers to the identification information management table of the registration information server 4 via the slave unit interface 16 and determines the input personal information. It is determined whether the identification information is stored in the registration information server 4. If the handset control unit 11 determines that the identification information of the input personal information is not stored in the registration information server 4, the intra-group priority corresponding to the group name input by the group name input unit 13 Based on the information, image information and a calling signal are transmitted to the parent device 3 of the group.

  Further, when the handset control means 11 determines that the identification information of the personal information input by the personal information input means 15 is stored in the registered information server 4, the personal information stored in the personal setting information storage unit 10b Get configuration information. The personal setting information storage unit 10b stores a management table of personal setting information shown in FIG. The first column of the personal setting information management table indicates each visitor individual, and the second column indicates priority callee information associated with each individual.

  Further, after acquiring the personal setting information from the personal setting information storage unit 10b, the handset controller 11 acquires the priority call destination information associated with the individual from the priority call destination information storage unit 10c. The priority call destination information storage unit 10c stores a priority call destination information management table shown in FIG. The first column of the priority call destination information management table indicates each priority call destination information, and the second and subsequent columns indicate the parent device 3 that is called preferentially in each group. The slave unit control means 11 has acquired the priority call destination information from the priority call destination information storage unit 10c, and then has the master unit 3 to be called preferentially in the group with the group name input by the group name input means 13 set? Determine whether or not.

  In addition, when it is determined that the parent device 3 to be preferentially called in the group is not set, the child device control unit 11 outputs an image to each parent device 3 in the group based on the intra-group priority information. Send information and call signals.

  Further, when it is determined that the parent device 3 to be preferentially called in the group is set, the child device control means 11 preferentially images the specific parent device 3 based on the priority call destination information. When there is no response after transmitting the information and the calling signal, the image information and the calling signal are transmitted to each parent device 3 of the group based on the intra-group priority information.

  The base unit 3 is provided with a base unit interface 23, a base unit control unit 24, and a notification unit 25. As the notification means 25, a display, a speaker, etc. are used, for example. The base unit control unit 24 receives the image information and the calling signal from the handset unit control unit 11 through the base unit interface 23, displays the image information on the notification unit 25, and sounds the ringing tone. Is notified. Further, the master unit control means 24 transmits a response signal to the slave unit control means 11 when a response operation is performed by the user. When the response signal from one parent device 3 is received, the child device control means 11 transmits a call end signal to the other parent device. In addition, when a response signal from one parent device 3 is received, the child device control means 11 starts a call communication with the parent device control means 24 of the parent device 3. When the call end operation is performed by the user, the slave unit control unit 11 and the base unit control unit 24 transmit a call end signal to each other and end the call communication. In addition, the subunit | mobile_unit control means 11 and the main | base station control means 24 are the memory | storage parts (ROM and RAM) which memorize | store information, such as a program, and the arithmetic processing part (A and B) which performs arithmetic processing based on the information which the memory | storage part has memorize | stored CPU). In this embodiment, the slave unit control unit 11 is a call control unit, and the registration information server 4 and the slave unit memory unit 10 are memory units. Further, in this embodiment, the call operations performed on the handset 1 are an operation of inputting a group name with the group name input means 13 and an operation of inputting personal information with the personal information input means 15.

  Next, the operation will be described. FIG. 7 is a flowchart showing call operation support control by the handset controller 11 of FIG. In the figure, when the handset 1 is activated, the group name of the group information stored in the group information storage unit 10a is displayed on the display means 12 (step S1), and the group name is input by the group name input means 13. It is determined whether or not it is input (step S2). When it is determined that the group name is input by the group name input unit 13, an image at the time of operation is acquired by the photographing unit 14 (step S3), Guidance prompting to input information is displayed on the display means 12 (step S4), and it is determined whether or not personal information is input within a predetermined time by the personal information input means 15 (step S5).

  At this time, when it is determined that the personal information is not input by the personal information input means 15 within a predetermined time, the priority information of the group corresponding to the input group name is acquired from the group information storage unit 10a ( In step S6), image information and a call signal are transmitted to the parent device 3 having the highest priority in the group (step S7), and whether a response signal from the parent device 3 is received within a predetermined time. Is determined (step S8). At this time, if it is determined that the response signal from the master unit 3 is received within a predetermined time, a call end signal is transmitted to the other master unit 3 (step S9), and a response signal is transmitted. A call start signal is transmitted to the base unit 3 (step S10), call communication with the base unit control means 24 of the base unit 3 is connected (step S11), and a call end operation is performed by the user. It is determined whether or not (step S12). When it is determined that the user has performed a call termination operation, the call communication is terminated, and this call operation response control is also terminated. This call operation support control is repeatedly performed when the handset 1 is activated.

  On the other hand, when it is determined that the response signal has not been received within the predetermined time, it is determined whether or not there is a parent device 3 having the next highest priority in the group (step S13). When it is determined that there is a parent device 3 having a high degree, image information and a call signal are transmitted to the parent device 3 (step S14), and a response signal from each parent device 3 is received within a predetermined time. If it is determined whether or not a response signal has been received, it is determined again whether or not there is a parent device 3 having the next highest priority. At this time, if it is determined that there is no parent device 3 having the next highest priority, a call end signal is transmitted to each parent device 3 and a message indicating that there is no response is displayed on the display means 12 ( Step S15).

  On the other hand, if it is determined that the personal information is input by the personal information input means 15 within a predetermined time after the guidance prompting the user to input the personal information is displayed on the display means 12, the personal information is included in the personal information. It is determined whether or not the identification information is stored in the registration information server 4 (step S16). If it is determined that the identification information included in the personal information is stored in the registration information server 4, the personal setting information The personal setting information is acquired from the storage unit 10b, and the priority call destination information is acquired from the priority call destination information storage unit 10c. Based on the priority call destination information, priority is given to the group corresponding to the input group name. It is determined whether or not the parent device 3 to be called is set (step S17). At this time, when it is determined that the parent device 3 to be called preferentially is set, image information and a calling signal are transmitted to the parent device 3 (step S18), and a response from the parent device 3 is sent. When it is determined whether or not a signal is received within a predetermined time, and it is determined that a response signal from the parent device 3 is received within a predetermined time, a call with the parent device control means 24 of the parent device 3 If communication is connected and it is determined that the response signal from the parent device 3 has not been received within a predetermined time, image information and information are sent to each parent device 3 based on the group information corresponding to the input group name. A ringing signal is transmitted.

  On the other hand, when it is determined that the identification information included in the input personal information is not stored in the registration information server 4, and the parent device that is called preferentially in the group corresponding to the input group name If it is determined that 3 is not set, the image information and the call signal are not transmitted preferentially to the specific master unit 3 based on the priority call destination information, and the input group name is set. Image information and a call signal are transmitted to each parent device 3 based on the corresponding group information.

  In such an intercom system, the slave unit control means 11 stores personal setting information when the registration information server 4 stores identification information that matches the identification information of the personal information input by the personal information input means 15. When there is no response after preferentially transmitting image information and a call signal to a specific base unit 3 based on the personal setting information of the unit 10b and the priority call destination information of the priority call destination information storage unit 10c In addition, since the image information and the call signal are transmitted to each other base unit 3, the visitor can preferentially respond to the call, and even if the visitor is out of the seat, the other person can respond to the call. it can. That is, it is possible to deal with calls more reliably while reducing the trouble of handling unnecessary calls.

  The slave unit control means 11 stores the identification information that matches the identification information of the personal information input by the personal information input means 15 in the registration information server 4 while the group name is input by the group name input means 13. The image information and the call signal are preferentially transmitted to the specific master unit 3 based on the personal setting information in the personal setting information storage unit 10b and the priority call destination information in the priority call destination information storage unit 10c. After that, when there is no response, a call signal is transmitted to the base unit 3 of the group, so that it is possible to reduce the possibility that a user who is not related to the visitor responds to the call, and an unnecessary call. It is possible to further reduce the labor corresponding to the above.

  Further, the slave unit control means 11 receives the group name from the group name input means 13 and stores the identification information that matches the identification information of the personal information input by the personal information input means 15 in the registration information server 4. The image information and the call signal are preferentially transmitted to the specific master unit 3 based on the personal setting information in the personal setting information storage unit 10b and the priority call destination information in the priority call destination information storage unit 10c. Then, if there is no response, a call signal is transmitted to each parent device 3 in the group based on the call priority. And the possibility of hindering business operations can be reduced.

  In the first embodiment, it has been described that the priority call destination information in the priority call destination information storage unit 10c is information for preferentially calling one base unit 3, but the interphone parent that is preferentially called. The number of machines is arbitrary. For example, a plurality of parent machines 3 in the group may be called preferentially over the other parent machines 3 in the group.

  Further, in the first embodiment, it has been described that the priority call destination information storage unit 10c that stores the priority call destination information is provided in the handset 1. However, the registration information server 4 may be provided, and the user may The IC card 21 may be provided. When the priority call destination information is stored in the user information storage device, it is not necessary to input the group name by the group name input means, and the convenience of visitors with high visit frequency can be improved.

  Further, in the first embodiment, it has been described that personal identification is performed using the identification information of the IC card 21 carried by the user and the identification information of the registration information server 4, but for example, fingerprint, retinal iris, palm shape Individual identification may be performed using a face, voice, or the like. When these are used for personal identification, priority callee information is stored in memory means provided on the network.

Embodiment 2. FIG.
FIG. 8 is a block diagram showing an intercom system according to Embodiment 2 of the present invention. FIG. 9 is an explanatory diagram showing a management table of information stored in the main part of the slave unit 30 of FIG. In the first embodiment, the registration information server 4 is provided on the network. However, in the second embodiment, the registration information server 4 is omitted. The slave unit 30 of the second embodiment includes a slave unit memory unit 31, a slave unit control unit 32, a display unit 12, a group name input unit 13, a photographing unit 14, and a slave unit interface 16. It has been. The handset memory means 31 includes a group information storage unit 10a, a face information storage unit 31a, and a callee information storage unit 31b when it cannot be detected. The face information storage unit 31a stores face information indicating general human face characteristics (for example, positional relationship between eyes, nose, and mouth). The face information stored in the face information storage unit 31a is not information for identifying a visitor's face, but information used for determining the presence or absence of a human face. The non-detectable call destination information storage unit 31b stores a management table of non-detectable call destination information (specific callee information) shown in FIG. The non-detectable call destination information is information for calling the first group of parent devices 3 (specific parent device 3).

  The slave unit control unit 32 detects a human face from the image photographed by the photographing unit 14 when a group name is input by the group name input unit 13 (when a call operation is performed by the slave unit 30). It is determined based on the face information in the face information storage unit 31a. If the handset control unit 32 determines that the human face can be detected from the image captured by the image capturing unit 14, the intra-group priority corresponding to the group name input by the group name input unit 13. Based on the information, image information and a call signal are transmitted to each parent device 3.

  If the handset controller 32 determines that it is impossible to detect a human face from the image captured by the capturing means 14, the handset controller 32 invalidates the call operation performed on the handset 30, and Based on the non-detectable call destination information stored in the non-detectable call destination information storage unit 31b, image information and a call signal are transmitted to the specific master unit 3. Further, the slave unit control means 32 transmits the image information and the call signal to the specific master unit 3 based on the call destination information when it cannot be detected, and then the response signal from the master unit 3 is received within a predetermined time. When it is determined that the call is not received, a call end signal is input to the master unit 3 and a message indicating that there is no response is displayed on the display unit 12. Other configurations are the same as those in the first embodiment. In this embodiment, the group name input unit 13 is a callee information input unit, the slave unit control unit 32 is a call control unit, and the registration information server 4 and the slave unit memory unit 31 are memory units. .

  Next, the operation will be described. FIG. 10 is a flowchart showing the call operation support control performed by the handset controller 32 of FIG. In the figure, after a group name is input by the group name input means 13 and an image at the time of operation of the group name input means 13 is acquired using the photographing means 14, the face information in the face information storage unit 31a is used to It is determined whether or not a face can be detected from the image (step S20). At this time, when it is determined that a face can be detected from the image, image information and a call signal are transmitted to each parent device 3 based on the group information in the group information storage unit 10a. It is determined whether or not a response signal is input. That is, when it is determined that a face can be detected from the acquired image, the same operation as when no personal information is input in the intercom system of the first embodiment is performed.

  On the other hand, when it is determined that it is impossible to detect a face from the acquired image, a specific parent device is determined based on the non-detectable call destination information in the non-detectable call destination information storage unit 31b. 3 is transmitted with image information and a call signal (step S21), it is determined whether or not a response signal from the parent device 3 is received within a predetermined time, and it is determined that a response signal has been input. If it is determined that the call communication with the parent device 3 is started and no response signal is received, a call end signal is transmitted to the parent device 3 and the display means 12 does not respond. Is displayed.

In such an intercom system, the slave unit control unit 32 determines whether or not a human face can be detected from the image captured by the imaging unit 14 when the group name is input by the group name input unit 13. When it is determined that a human face can be detected, a call signal is transmitted to a predetermined parent device 3 based on the group information corresponding to the input group name, and it is determined that the human face cannot be detected. In this case, the group name input by the group name input means 13 is invalidated, and a call signal is sent only to a specific master unit 3 based on the call destination information when it cannot be detected in the call destination information storage unit 31b when it cannot be detected. Because it is transmitted, for example, when a call operation is performed with the face hidden intentionally, such as a call by a suspicious person or a call by prank, a specialized department can deal with it, It is possible to reduce the physical burden, general users can be reduced the effort corresponding to unnecessary call.
In addition, the conventional system has a problem that even if a visitor to be handled performs a call operation, if the face cannot be photographed normally, the call is not notified and the call of the visitor cannot be handled. In the intercom system according to this embodiment, even if a face cannot be photographed normally, a specialized department can handle the call, so that the call can be handled more reliably.

  In the second embodiment, it has been described that the callee information when detection is impossible is information set in units of groups. However, interphone master units may be individually set as shown in FIG.

  In the first and second embodiments, the master unit 3 is described as being managed by being divided into a plurality of groups. However, when this interphone system is applied to a small office, for example, each interphone There is no need to divide the master unit into groups.

Embodiment 3 FIG.
FIG. 12 is a block diagram showing an intercom system according to Embodiment 3 of the present invention. In the second embodiment, it has been described that the individual identification of the visitor is not performed. However, whether or not to enable the call operation based on whether or not a human face can be detected from the image captured by the imaging unit 14 is determined. Even in the intercom system to be determined, a call signal may be preferentially transmitted to a specific parent device 3 based on personal identification. The intercom system shown in FIG. 12 is a combination of the intercom system of the first embodiment and the intercom of the second embodiment.

  Next, the operation will be described. FIG. 13 is a flowchart showing a part of the call operation support control by the handset controller 42 of FIG. FIG. 14 is a flowchart showing a continuation of FIG. In the figure, when a group name is input by the group name input means 13, an image at the time of operation is acquired by the photographing means 14, and it is determined whether or not a human face can be detected from the image. At this time, if it is determined that it is impossible to detect a person's face, an image of the specific master unit 3 is displayed based on the callee information when it cannot be detected in the callee information storage unit 31b when it cannot be detected. Information and call signals are transmitted. That is, when it is determined that it is impossible to detect a human face, the operation described in the second embodiment is performed.

  On the other hand, when it is determined that a person's face can be detected, guidance for prompting to input personal information is displayed on the display unit 12 and the personal information is input by the personal information input unit 15 for a predetermined time. It is determined whether or not it is input to the inside. In other words, when it is determined that a human face can be detected, the operation described in the first embodiment is performed.

  Thus, based on whether or not a person's face can be detected from the image captured by the image capturing means 14, it is determined whether or not the call operation is valid, and a visitor's personal identification is performed to identify a specific person. By calling the parent device 3 preferentially, it is possible to more reliably handle calls while reducing the trouble of dealing with unnecessary calls more reliably.

  In the third embodiment, the case where each parent device 3 is managed by being divided into groups has been described. However, the interphone parent device may not be managed by being divided into groups, and in this case, personal information input means The situation when personal information is input in is photographed by the photographing means, and if the face of a person cannot be detected from the image, the input personal information is invalidated and the callee information storage unit when it cannot be detected The image information and the calling signal are transmitted to the specific parent device based on the callee information when the detection is impossible.

  In the first to third embodiments, six master units 3 are provided and each master unit 3 is managed by being divided into four groups. However, the number of interphone master units and groups is arbitrary. It is.

  Further, in the first to third embodiments, it has been described that the slave unit control means 11, 32, 42 generates the calling signal. However, the master unit control unit of a specific master unit is based on information input by the slave unit. A call signal may be generated. That is, the parent device control means of a specific parent device may also serve as the call control means. The call control means may be provided in a dedicated machine provided on the network.
