Description

  The present invention relates to a system in which a biometric authentication device and a home security system are linked.

  In recent years, there has been an increase in the number of ordinary houses that introduce home security systems for crime prevention purposes. The home security system includes a door sensor, a passive sensor, an indoor sensor, or the like for detecting an intruder, and the sensor notifies an external security company, a resident, or the like when the intruder is detected. A system in which such a home security system is combined with a function for controlling equipment installed in a building such as lighting equipment and air conditioning equipment has also been proposed (Patent Document 1).

  Usually, the release of the security state by the home security system is based on the verification of the password input given from the numeric keypad installed at the entrance gate to the security area.

By the way, interphone devices with cameras are widely used in ordinary houses. A typical intercom apparatus includes an outdoor unit having a microphone and a moving image camera installed at a front door of a house, and an indoor unit having a speaker that emits sound and an image monitor. Such an intercom device is normally used in a stand-alone manner without being linked with other systems.

  In order to cancel the security state by the home security system, it is necessary to input a password as described above. In addition, there are systems that require other operations following password entry, and the inconvenience cannot be eliminated for residents. In addition, in the case of an elderly person or a resident of a child, the password may be forgotten and the security state may not be released. Furthermore, there is a risk that the intruder knows the password, and there is a risk that the security is accidentally released as a result of the intruder operating the numeric keypad when he / she encounters the password.

  On the other hand, an interphone device is a high-performance system having a moving image camera, but is often used as a stand-alone device, and operation in cooperation with other systems is desired from the viewpoint of effective use of the system.

  An object of the present invention is to provide a system capable of facilitating the release of a security state while maintaining security by a home security system. Another object of the present invention is to provide a system for effectively utilizing an intercom apparatus in cooperation with another system.

  A home security system according to one aspect of the present invention that achieves the above object is provided with a home security controller that performs a predetermined security operation based on an input of a monitoring signal, and is communicably connected to the home security controller. A biometric authentication device that performs a biometric authentication operation, wherein the biometric authentication device acquires biometric information and inputs a signal related to the biometric information, and is allowed to enter the security area. The storage means for storing the biometric information of the permitted person, the biometric information input from the input means and the biometric information stored in the storage means are collated to determine whether or not the input is made by the permitter. A determination means for determining and the home security controller when the determination means determines that the input is made by the authorized person; Characterized in that it comprises an output means for outputting a security release signal (claim 1).

  According to this configuration, it is possible to operate the home security controller and the biometric authentication device in cooperation with each other. In other words, since the security release determination is performed based on the biometric information of the permitted person stored in the storage means, it is possible to store the biometric information of the resident in advance so that the resident can enter the security area. The operation for releasing the security state can be facilitated. On the other hand, security against the entry of a non-permitted person (intruder) into the security area, on the contrary, requires verification of biometric information.

  In the above configuration, an outdoor unit that includes an imaging device that is installed at an entrance gate to the security area and that can acquire image information, and an indoor unit that is installed in the security area and includes a display unit that can display the image information; It is preferable that the intercom apparatus includes the intercom apparatus and the biometric authentication apparatus that are communicably connected to each other, and the imaging apparatus is used as the input unit of the biometric authentication apparatus.

  According to this configuration, biometric authentication can be performed based on information acquired by the outdoor unit of the interphone device, that is, image information acquired by the imaging device, or voice data picked up by the microphone. Therefore, the intercom device and the home security controller can be operated in cooperation.

  Alternatively, the biometric authentication device may be installed at an entrance gate into the security area (claim 3). According to this configuration, since the biometric information is directly acquired by the biometric authentication device, the device configuration can be simplified.

  In this case, it is desirable that the biometric authentication device has a function of an outdoor unit of an intercom device (claim 4). According to this configuration, since the biometric authentication device installed at the entrance gate also functions as the outdoor unit of the interphone device (camera, microphone function), the interphone device and the home security controller can be operated in cooperation. it can.

  An access permission system according to another aspect of the present invention is a control that controls a state of the living area between a first mode that does not allow an access operation to a predetermined living area and a second mode that allows the access operation. And a biometric authentication apparatus that is communicably connected to the control means and acquires biometric information and performs biometric authentication operation. The biometric authentication apparatus acquires biometric information and outputs a signal related to the biometric information. Input means for inputting; storage means for storing biometric information of a permitted person permitted to access the living area; biometric information input from the input means; and biometric information stored in the storage means When the collating unit determines that the input is from the permitter, and the determination unit determines that the input is from the permitter, the control unit is configured to input the occupancy error. Characterized in that it comprises an output means for outputting a release signal to shift the state of A from the first mode to the second mode (claim 5).

  According to this configuration, since it is a system in which whether or not access to the living area is permitted is determined on the condition that collation by the biometric authentication device is performed, the permitter can easily access the living area only by performing a biometric authentication operation ( It is possible to unlock the door and make a call with a person at home. On the other hand, non-permitted persons (intruders) are required to collate biometric information, and therefore can be made in a state where access to the living area cannot be performed at all.

  In the above configuration, an intercom device including an outdoor unit installed at an entrance gate to the living area and an indoor unit installed in the living area, and the control means when the first mode, The communication between the outdoor unit and the indoor unit is disabled, and in the second mode, the communication between the outdoor unit and the indoor unit can be performed (Claim 6).

  According to this configuration, when authenticated by the biometric authentication device, the intercom device can be communicated with the outdoor unit and the indoor unit (first mode). It is assumed that the used communication itself cannot be performed (second mode). Accordingly, it is possible to realize a system operation in which a visitor who does not wish for a resident can be denied access through the intercom device.

  Alternatively, in the above configuration, the control means is a home security controller for the living area, and the home security controller performs a predetermined security operation based on an input of a monitoring signal and the security operation. It is possible to change the security state between the second mode and the home security controller when the release signal is given, and the home security controller shifts the security state from the first mode to the second mode. It can be set as a structure (Claim 7).

  According to this configuration, when authenticated by the biometric authentication device, the home security controller cancels the security state and enters a state where the user can enter the living area (second mode). On the other hand, if the authentication cannot be obtained, the home security controller maintains the security state and continues the state in which entry into the living area is impossible (first mode). Therefore, it is possible to easily and surely perform access restriction / permission between an authorized person and an unpermitted person in cooperation with the biometric authentication device and the home security controller.

  According to the home security system and the access permission system according to the present invention, the home security system, the intercom device, and the biometric authentication device are linked to maintain the security by the home security system, but to the security state for the authorized person. Can be easily released. In addition, an intercom device that has been stopped in a stand-alone manner can be effectively used in cooperation with a biometric authentication device.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is a configuration diagram showing a schematic configuration of a home security system S1 according to the first embodiment. The home security system S1 is installed in a house H and includes a biometric authentication device 1, a home security controller 2, and an interphone device 3 including an outdoor unit 31 and an indoor unit 32.

  The outdoor unit 31 and the indoor unit 32 of the intercom device 3 are connected by an interphone line 301, and the indoor unit 32 and the biometric authentication device 1 are connected by a signal cable 302 capable of transmitting a signal including image data. The biometric authentication device 1 and the home security controller 2 are connected by a LAN cable 101. Instead of using the LAN cable 101, both may be connected to each other via a wireless LAN.

  In this embodiment, the biometric authentication device 1 is a device for performing personal authentication based on biometric information extracted from visitor image information and / or audio information acquired by the outdoor unit 31 of the intercom device 3. . Furthermore, in this embodiment, it has a function which produces | generates the control signal which makes the home security controller 2 change or maintain a security mode according to the result of the said personal authentication. This point will be described in detail with reference to FIG.

  The home security controller 2 is a controller that controls a predetermined security operation performed based on an input of a monitoring signal. A monitoring sensor 21 for inputting the monitoring signal is connected to the home security controller 2. The monitoring sensor 21 is, for example, a door sensor, a passive sensor, or an indoor sensor for detecting an intruder.

  The home security controller 2 can change the security state between the first mode in which the security operation is performed based on the input of the monitoring signal and the second mode in which the security operation is not performed. Although the change of the security state is normally performed by a user's manual operation, in the present embodiment, the change is also made by a control signal given from the biometric authentication device 1.

  The outdoor unit 31 of the intercom device 3 is installed at the entrance (entrance gate) of the house H (in the security area). The outdoor unit 31 includes an imaging device 311 that acquires facial image information mainly for visitors, and a voice input / output unit 312 for performing voice communication between the visitors and the home-stayers. Here, the imaging device 311 is, for example, a television camera that captures a color or monochrome moving image. The voice input / output unit 312 includes a microphone and a speaker.

  The indoor unit 32 is installed in a suitable place of the house H by, for example, a wall hanging method. The indoor unit 32 includes a monitor 321 (display unit) that displays a two-dimensional moving image captured by the imaging device 311 of the outdoor unit 31 and a voice input / output unit 322 for performing voice communication. Here, the monitor 321 is, for example, a small liquid crystal display. Similarly, the voice input / output unit 322 includes a microphone and a speaker.

  Next, functional configurations of the biometric authentication device 1 and the home security controller 2 will be described. FIG. 2 is a functional block diagram of the home security system S1. The biometric authentication device 1 functionally includes a biometric information input unit 11 (input unit), a storage unit 12 (storage unit), an authentication processing unit 13 (determination unit), and a control signal output unit 14 (output unit). The home security controller 2 (control means) includes a mode setting unit 22, a security control unit 23, and a communication unit 24.

  The biometric information input unit 11 acquires biometric information necessary for biometric authentication and inputs a signal related to the biometric information to the authentication processing unit 13. In the present embodiment, the biological information is visitor face image data provided from the imaging device 311 included in the outdoor unit 31 of the intercom device 3 and visitor voice data provided from the voice input / output unit 312. The face image data can be used for biometric authentication, for example, by collating face patterns. The voice data can be used for biometric authentication by collating voiceprint patterns, for example.

  The storage unit 12 stores biometric information data of an allowed person permitted to enter the house H. Here, the permitted person is usually a resident of the house H. For example, when biometric authentication is performed by collating face patterns, feature data on the face pattern of the permitted person is stored in the storage unit 12. In addition, when performing biometric authentication by collating voiceprint patterns, feature data regarding the voiceprint pattern of the permitted person is stored in the storage unit 12. These characteristic data are acquired from an authorized person in advance by the data input means 15 including a camera and / or a microphone, and are input to the storage unit 12 as personal identification data.

  The authentication processing unit 13 collates the biometric information input from the biometric information input unit 11 and the biometric information stored in the storage unit 12 to determine whether or not the data related to the input belongs to the authorized person. To do. For example, the authentication processing unit 13 uses the feature amount extracted from the visitor's face image data acquired by the intercom device 3 using a face template or the like, and the permitted person's face image data stored in the storage unit 12 in advance. The feature amount extracted from the image is compared, and it is determined whether or not the image is input by the permitted person based on the degree of coincidence between the two. Then, the authentication processing unit 13 gives the determination result to the control signal output unit 14. Needless to say, if the input is a pre-registered permitted person, a “match” determination is made, and if the input is a non-permitted person, a “mismatch” determination is made.

  The control signal output unit 14 generates a control signal for changing the operation mode of the home security controller 2 according to the personal authentication result by the authentication processing unit 13. Specifically, when the authentication processing unit 13 determines “match”, the control signal output unit 14 outputs a security release signal to the home security controller 2. On the other hand, when the authentication processing unit 13 makes a “mismatch” determination, a security maintenance signal is output.

  The mode setting unit 22 makes the home security controller 2 perform a security operation based on an input of a monitoring signal in response to an operation signal given from the user through the operation unit 25, or a mode that does not perform the security operation. Set the mode to one of the two modes. The operation unit 25 is an operation button or a numeric keypad provided on the home security controller 2. In general, when the resident is absent, the mode setting unit 22 sets the home security controller 2 to the first mode in response to a signal from the operation unit 25 in the midnight time zone, and sets the second mode when the resident is away from midnight. .

  Further, the mode setting unit 22 changes the operation mode of the home security controller 2 not only by a manual operation signal given from the operation unit 25 but also by a control signal given from the control signal output unit 14. When the security operation is being executed in the first mode and the security release signal is given from the control signal output unit 14, the mode setting unit 22 changes the setting from the first mode to the second mode, and performs security control. The security operation by the unit 23 is stopped. For this reason, the resident of the house H can enter the house H only by imaging his / her face with the intercom device 3. This eliminates the burden of entering the password of the resident and fundamentally solves the problem of forgetting the password.

  On the other hand, when the security maintenance signal is given from the control signal output unit 14, the mode setting unit 22 maintains the first mode and continues the security operation. That is, the state which does not enter the house H is continued. In this way, it is easy for residents of the house H to enter, whereas for non-permitted persons (intruders), since the verification of biometric information is a condition, the security is accidentally released. It is virtually impossible to enter. In this case, the control signal output unit 14 performs control to utter a voice message such as “cannot enter because the authentication could not be obtained” via the outdoor unit 31 of the intercom device 3. It is desirable.

  The security control unit 23 is operated by a program stored in a ROM or the like, and performs a security operation in the first mode. Specifically, the security control unit 23 controls the sensing operation of the monitoring sensor 21 to acquire monitoring data every predetermined sampling period, and monitors the occurrence of abnormality. When an abnormality is detected based on a signal input from the monitoring sensor 21, the security control unit 23 transmits an abnormality notification signal via the communication unit 24 and activates the alarm device 26 to perform a predetermined alarm operation. To do. Here, the alarm device 26 is, for example, a speaker that emits an alarm sound, an alarm lamp that emits alarm light, or the like.

  The communication unit 24 is connected to an external telecommunication line such as the Internet IN, and outputs an alarm message to the external terminal device 4 when the security control unit 23 detects an abnormality. The terminal device 4 is, for example, a security system terminal belonging to a preset external security company, or a mobile terminal such as a mobile phone or a personal computer owned by a resident.

  The operation of the home security system S1 according to the present embodiment described above will be described. FIG. 3 is a flowchart showing a cooperative operation between the biometric authentication device 1 and the home security controller 2.

  When an operation instruction for starting security is given from the operation unit 25 by the user (step S11), the mode setting unit 22 sets the home security controller 2 to the first mode in which the security operation is performed (step S12), and starts the security operation. . Thereafter, when an abnormality is detected via the monitoring sensor 21, the security control unit 23 performs a predetermined security operation, but the flow is omitted.

  In the state of the first mode, the authentication processing unit 13 of the biometric authentication device 1 waits for input of biometric information from the biometric information input unit 11 (step S13). When the biometric information of the accessing person is input through the intercom device 3 (YES in step S13), authentication processing is performed in the authentication processing unit 13 (step S14). As described above, this authentication process is a process for determining the coincidence between the biometric information of the permitted person stored in advance in the storage unit 12 and the biometric information acquired from the intercom device 3. In accordance with the determination result, it is determined whether or not the accessing person is an allowed person (step S15).

  As a result of the determination, if the “match” determination is made (YES in step S15), it is determined that the accessing person is an allowed person. In this case, the control signal output unit 14 outputs a security release signal to the mode setting unit 22 (step S16). In response to this, the mode setting unit 22 changes the setting of the security mode from the first mode to the second mode (step S17), stops the monitoring operation by the security control unit 23, and releases the security (step S18).

  On the other hand, as a result of the determination, if the “mismatch” determination is made (NO in step S15), it is determined that the accessing person is an allowed person. In this case, the control signal output unit 14 outputs a security maintenance signal to the mode setting unit 22 (step S19). The output of the security maintenance signal may be omitted. And the control signal output part 14 performs notification of entry rejection, for example via the outdoor unit 31 of the intercom apparatus 3 (step S20). Then, it returns to step S12 and repeats a process.

  On the other hand, when the security release is performed, it is confirmed whether or not the security operation is resumed (step S21). When restarting (YES in step S21), the process returns to step S12 to repeat the process. If not restarted (NO in step S21), it is confirmed whether or not the system is to be stopped (terminated) (step S22), whether the process is ended (YES in step S22) or waiting (NO in step S22). Selected.

  According to the home security system S1 as described above, the home security controller 2 and the intercom device 3 and the biometric authentication device 1 are linked to each other so that it is easy for an authorized person to release the security state while maintaining security. Can be In addition, the intercom device 3 is not limited to stand-alone use, and can be effectively used in cooperation with the biometric authentication device 1.

[Second Embodiment]
FIG. 4 is a configuration diagram showing a schematic configuration of the home security system S2 according to the second embodiment. The home security system S2 includes a biometric authentication device 10 that is installed in a house H and has an interphone device outdoor unit function, a home security controller 2, and an interphone indoor unit 320 (interphone device 3). Yes.

  In the second embodiment, the biometric authentication device 10 is installed at the entrance (entrance gate) of the house H (in the security area), and has an imaging function for acquiring mainly facial image information of the visitor, and the visitor and the home. Voice input / output for voice communication with a person. Thus, since the biometric authentication device 10 also functions as an outdoor unit of the intercom device, only the indoor unit 320 is installed in the house H as the interphone device. The indoor unit 320 and the biometric authentication device 10 are connected by an intercom line 303. The home security controller 2 and the monitoring sensor 21 are the same as those in the first embodiment, and the home security controller 2 and the biometric authentication device 10 are connected by a LAN cable 102.

  Home security system S2 concerning a 2nd embodiment is a system which added the function which can also refuse access via an intercom device to the visitor who does not want for the resident of house H. That is, the biometric authentication device 10 performs biometric authentication at the entrance of the entrance or the apartment house, and when it is determined that the person is not permitted to access, the communication with the intercom device 3 can be rejected. If it is determined that the access is permitted, communication with the intercom device 3 is permitted, and if the access is permitted, the security is also released.

  FIG. 5 is a functional block diagram of the home security system S2. The biometric authentication device 10 functionally includes a biometric information input unit 111 (input unit), a storage unit 12 (storage unit), an authentication processing unit 13 (determination unit), an operation control unit 141 (output unit / control unit), and communication. A gate 16 is provided. The home security controller 2 (control means) includes a mode setting unit 22, a security control unit 23, and a communication unit 24. Note that the portions denoted by the same reference numerals as those in FIG. 2 are portions that perform the same function, and thus the description thereof is omitted or simplified here.

  The biometric information input unit 111 is a functional unit that acquires biometric information necessary for biometric authentication and inputs a signal related to the biometric information to the authentication processing unit 13. Here, the image pickup device 112 that also serves as an interphone image acquisition means and obtains a visitor's face image data for biometric authentication, and obtains the visitor's voice data for biometric authentication that also serves as an interphone sound acquisition means. In this example, a voice input / output unit 113 is provided. In addition to this, other biological information acquisition means may be included. For example, the biological information input unit 111 may include a fingerprint reader for acquiring fingerprint information.

  The storage unit 12 stores biometric information data of an allowed person allowed to enter the house H according to the biometric information acquired by the biometric information input unit 111. The authentication processing unit 13 collates the biometric information input from the biometric information input unit 111 and the biometric information stored in the storage unit 12 to determine whether the input data is that of the authorized person. To do.

  The operation control unit 141 mainly has two functions. The first function is an interphone communication blocking function, and the second function is a security release. For the first function, the operation control unit 141 turns off the communication gate 16 when the personal authentication result of the authentication processing unit 13 is “mismatch” (first mode). The communication gate 16 is a gate element that is interposed in a communication line between the biological information input unit 111 (sound input / output unit 113) and the indoor unit 320. When the communication gate 16 is turned off, communication between the two becomes impossible. It is. On the other hand, when the personal authentication result of the authentication processing unit 13 is “match” (second mode), the operation control unit 141 turns on the communication gate 16 and performs communication between the voice input / output unit 113 and the indoor unit 320. Make it possible.

  For the second function, the operation control unit 141 generates a control signal for changing the operation mode of the home security controller 2 according to the personal authentication result by the authentication processing unit 13. Specifically, when the authentication processing unit 13 determines “match”, the operation control unit 141 outputs a security release signal to the home security controller 2. On the other hand, when the authentication processing unit 13 makes a “mismatch” determination, a security maintenance signal is output. This function is the same function as the control signal output unit 14 of the first embodiment. Upon receiving these control signals, the home security controller 2 functions in the same manner as in the first embodiment.

  The operation of the home security system S2 according to the second embodiment described above will be described. FIG. 6 is a flowchart showing a cooperative operation between the biometric authentication device 1 and the home security controller 2 in the second embodiment.

  When a user gives a security start operation instruction from the operation unit 25 (step S31), the mode setting unit 22 sets the home security controller 2 to the first mode in which the security operation is performed, and starts the security operation. Thereafter, when an abnormality is detected via the monitoring sensor 21, the security control unit 23 performs a predetermined security operation. At the same time, the operation control unit 141 turns the communication gate 16 OFF (closed) so that the intercom communication is cut off (step S32).

  In the state of the first mode, the authentication processing unit 13 of the biometric authentication device 1 waits for input of biometric information from the biometric information input unit 111 (step S33). When the accessor's biometric information is input through the biometric information input unit 111 (YES in step S33), authentication processing is performed in the authentication processing unit 13 (step S34). This authentication process is a process for determining the coincidence between the biometric information of the permitted person stored in advance in the storage unit 12 and the biometric information acquired from the biometric information input unit 111. Depending on the determination result, it is determined whether or not the accessing person is an allowed person (step S35).

  As a result of the determination, if the “match” determination is made (YES in step S35), it is determined that the accessor is an allowed person. In this case, the operation control unit 141 sets the communication gate 16 to ON (opened) to enable intercom communication (step S36).

  On the other hand, as a result of the determination, if the “mismatch” determination is made (NO in step S35), it is determined that the accessing person is an unpermitted person. In this case, the operation control unit 141 sets the communication gate 16 to an OFF (closed) state to maintain a state in which communication is impossible, and outputs a security maintenance signal to the mode setting unit 22 (step S37). The output of the security maintenance signal may be omitted. Then, for example, the operation control unit 141 notifies the entry refusal through the voice input / output unit 113 of the biological information input unit 111 (step S38). Then, it returns to step S32 and repeats a process.

  When “match” determination is made and the communication gate 16 is “open” (step S39), it is determined whether or not the security release is performed next. This is a step of discriminating whether the access person determined to be an authorized person is simply a visitor permitted to intercom communication, or of course, a resident permitted to enter the house H or the like. . This distinction is made based on biological information stored in the storage unit 12.

  If the accessor is a resident or the like (YES in step S39), the operation control unit 141 outputs a security release signal to the mode setting unit 22. In response to this, the mode setting unit 22 changes the setting of the security mode from the first mode to the second mode (step S40), stops the monitoring operation by the security control unit 23, and releases the security (step S41). When the access person is a visitor who is allowed to communicate with the intercom and is allowed to enter the house H, the mode is changed to the second mode by manual operation.

  On the other hand, when security release is not performed (YES in step S39), intercom communication is performed (step S42), and after waiting for the completion, the process returns to step S32 to repeat the process.

  On the other hand, when the security release is performed, it is confirmed whether or not the security operation is resumed (step S43). When restarting (YES in step S43), the process returns to step S32 and the process is repeated. If not restarted (NO in step S43), it is confirmed whether or not the system is to be stopped (terminated) (step S44), whether the process is ended (YES in step S44) or whether it is waiting (NO in step S44). Selected.

  Although two specific embodiments of the present invention have been described above, these are examples of the present invention, and can be implemented in a mode different from the above-described embodiments without departing from the spirit of the invention. For example, in the above embodiment, an example in which the present invention is applied to the house H has been described.
