Description

  The present invention relates to a security device and a security method.

  Conventionally, a security device that guards facilities such as office buildings, tenant buildings, and laboratories is known. In this security device, an arbitrary area in or around the building is set as a security area, and a security state in which the presence of a person in the security area is detected and reported, and even if the presence of a person is detected, no notification is made. Set to either the security release state. For example, in an office, the employee is set to the security release state during work hours such as working hours, and is set to the security state during the time when the employee leaves the company and leaves the office.

  In the conventional security device, the last person to leave the security area (the employee who leaves the company last) switches from the security release state to the security state, and the first person to enter the security area (the first employee who left the company) Switching from the security state to the security release state is performed.

  Also, if the last person leaving the security area forgets to switch to the security state, the security area will remain in the security release state, and even if an intruder enters the security area, it will not be reported. A technology that automatically switches to the security state when the scheduled time comes (for example, see Patent Document 1), or a technology that enables the security state to be set if the security state is not set even when the security set scheduled time comes (for example, , See Patent Document 2).

FIG. 4 is a flowchart showing a procedure of security processing executed by the security device according to the present embodiment. FIG. 5 is a flowchart showing a procedure of security processing different from that in FIG. 4 executed by the security device according to the present embodiment.

  Exemplary embodiments of a security device and a security method according to the present invention will be explained below in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram showing a security system including a security device according to the present embodiment. As shown in FIG. 1, the security system includes a security device 10 and a monitoring center 14.

  The security device 10 is a device that guards a security area to be monitored. The security device 10 is connected to the monitoring center 14 via the network 12.

  The network 12 is a communication network such as a telephone line, a wireless network, and the Internet, and connects the security device 10 and the monitoring center 14.

  The monitoring center 14 receives a report indicating an abnormality, a report indicating normality, and the like from the security device 10 that has detected an abnormality in the security area. When the monitoring center 14 receives a report indicating an abnormality, the monitoring center 14 instructs the waiting guard to go to the security area where the abnormality is detected and, if necessary, the related organizations such as the police and the fire department. The center that reports to Further, when receiving a report indicating an abnormality, the monitoring center 14 may be configured to transmit a notification to that effect to a mobile terminal such as a mobile phone held by a user who is out of the security area.

  The notification indicating an abnormality is a signal indicating that some kind of security processing based on the notification is required in the monitoring center 14 such as sending a guard to the security area or reporting to a related organization. Examples of reports indicating abnormalities include an intruder detection signal indicating that a suspicious person has entered the security area and a signal indicating that the door of the security area has been illegally unlocked. Not limited.

  The notification indicating normality is a registered person signal indicating that the person detected in the monitoring area is a registered person (described later in detail), but is not limited to this signal.

  In addition, the monitoring center 14 receives a signal indicating the security mode from the security device 10 via the network 12.

  Here, the “security mode” is a mode for determining the operation of the security device 10 when an abnormality is detected. That is, the “security mode” is a mode that determines whether or not to report to the reporting destination when abnormality is detected in the security area or whether or not notification to the security area is possible. The security mode includes a plurality of modes depending on whether or not a report can be made, a report destination, presence / absence of notification to a security area, and the like, and representative security modes include a security state and a security release state.

  First, the “security state” is a security mode that is set mainly when security is required such as when the user is absent. The security state is an alarm that notifies the monitoring center 14 of an abnormality when the security device 10 receives a detection signal that is issued when an abnormality is detected by a sensor (sensor 20, in FIG. 1, details will be described later) (detection unit). It is a state to report. In the security state, it may be notified by voice or light that an abnormality has been detected in the security area where the security device is installed. This is for the purpose of intimidating an intruder or for the purpose of prompting an alarm release operation in the case of misinformation.

  The “security release state” is a security mode set mainly when the user is in the room and does not require security. The security release state means that even if the security device 10 receives a detection signal that is generated when an abnormality is detected by the sensor, it is assumed that the sensor has detected a valid occupant, The alarm is not reported, and it is not determined that there is an abnormality in the security area.

  Next, details of the security device 10 will be described.

  Returning to FIG. 1, the security device main body 16 includes an input / output control unit 26, a control unit 28, a communication control unit 30, and a storage unit 32.

  The input / output control unit 26 controls data input / output with the imaging unit 18, the sensor 20, the operation unit 22, and the notification unit 24. The communication control unit 30 controls communication between the security device 10 and the monitoring center 14 via the network 12. Specifically, the communication control unit 30 is a network board or the like.

  The storage unit 32 is a storage medium such as a hard disk drive (HDD) and stores various types of information. In the present embodiment, the storage unit 32 stores biometric authentication information for specifying a registered person who is a person registered in advance. A registered person is a person other than the target person who corresponds as a suspicious person in the security system. More specifically, the registered person is a person who is permitted in advance to enter the security area, such as an employee working in the security area.

  The biometric authentication information includes information such as a face, an iris of the eyeball, a retina, a fingerprint, a palm, a blood vessel of a wrist, a hand pattern, a handwritten signature, and a voiceprint. In this embodiment, a case where a face image is used as biometric authentication information will be described.

  FIG. 3 is a diagram illustrating an example of a data structure of biometric authentication information stored in the storage unit 32. The storage unit 32 stores an employee ID, which is identification information for uniquely identifying a registered person, and face authentication data of the registered person specified by the employee ID in association with each other. In the present embodiment, the case where the storage unit 32 stores face authentication data will be described, but the face image itself may be stored. The identification information for uniquely identifying the registered person is not limited to the employee ID, and any identification information may be used.

  Returning to FIG. 1, the storage unit 32 sequentially stores the captured images acquired by the imaging of the imaging unit 18 in association with the imaging time.

  The storage unit 32 includes identification information of the imaging unit 18 that has captured the captured image, identification information of the sensor 20 provided at a position where a person in an area captured by the imaging unit 18 is detected, a captured image, and an imaging It is preferable to store the time in association with each other. In the present embodiment, a case will be described in which the storage unit 32 stores the identification information of the imaging unit 18, the identification information of the sensor 20, the captured image, and the imaging time in association with each other.

  The control unit 28 is a computer including a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and controls the entire security device 10.

  The control unit 28 includes a security mode switching unit 34 (corresponding to the switching unit of the present invention), a security mode storage unit 36, a reporting unit 38, a first control unit 40 (corresponding to the control unit of the present invention), and an accepting unit 42. A collation unit 44 and a measurement unit 46.

  The receiving unit 42 receives a switching instruction from the security release state to the security state or a switching instruction from the security state to the security release state from the operation unit 22.

  The security mode storage unit 36 is a storage medium such as a memory that stores various security modes and the current security mode in the security area. In the present embodiment, the security mode storage unit 36 stores the current security mode (security state or security release state).

  The security mode switching unit 34 switches the security mode to the security state or the security release state according to the switching instruction received by the reception unit 42. Specifically, the security mode switching unit 34, when the switching instruction received by the receiving unit 42 is a switching instruction from the security release state to the security state, the security mode stored in the security mode storage unit 36. Rewrite the information indicating the security status. As a result, the security mode switching unit 34 switches the security mode from the security release state to the security state. On the other hand, if the switching instruction received by the receiving unit 42 is a switching instruction from the security state to the security release state, the security mode switching unit 34 indicates the security mode stored in the security mode storage unit 36. To the security release state. As a result, the security mode switching unit 34 switches the security mode from the security state to the security release state.

  The reporting unit 38 reports to the monitoring center 14. The measuring unit 46 measures time. The measuring unit 46 uses a known timer function.

  The collation unit 44 captures an image included in a captured image corresponding to the detected time captured by the image capturing unit 18 when a person is detected in the security area when the security mode is switched to the security state. The person and the registered person stored in the storage unit 32 are collated.

  In the present embodiment, the collation unit 44 extracts a region of the face image of the captured person included in the captured image by a known face recognition method. Then, the collation unit 44 collates the imaged person with the registered person by determining whether or not the extracted face image matches the registered person's face image stored in the storage unit 32.

  When the feature information of the registered person's face is stored as a face image in the storage unit 32, the collation unit 44 extracts the feature information in the face image of the captured person included in the captured image by a known method. To do. The collation unit 44 collates the imaged person with the registered person by determining whether or not the extracted feature information matches the facial feature information of the registered person stored in the storage unit 32. Just do it. That is, the collation unit 44 may collate the captured person and the registered person included in the captured image by a method according to the biometric authentication information of the registered person stored in the storage unit 32. It is not limited to collation.

  In addition, when a captured image includes a plurality of captured persons, the collation unit 44 collates each registered person with a registered person in the same manner as described above.

  When the current security mode is the security state, the first control unit 40 controls the reporting unit 38 to report a signal indicating an abnormality to the monitoring center 14 when a person is detected by the sensor 20. (Details will be described later). In addition, when the current security mode is the security release state, the first control unit 40 notifies the monitoring center 14 of a signal indicating an abnormality even if a person is detected by the sensor 20. 38 is controlled. In addition, the 1st control part 40 specifies whether the information which shows the security mode stored in the security mode memory | storage part 36 is the information which shows a security state, or the information which shows a security cancellation | release state, What is necessary is just to specify the present security mode.

  In addition, when the captured person included in the captured image is a registered person, the first control unit 40 is a signal indicating that the person detected by the sensor 20 in the security state is a registered person (registered person signal). The reporting unit 38 is controlled so as to report. At this time, the first control unit 40 controls the security mode switching unit 34 so as to switch the security mode from the security state to the security release state.

  Next, a procedure of security processing executed by the security device 10 will be described. FIG. 4 is a flowchart illustrating a procedure of security processing executed by the security device 10 according to the present embodiment.

  The control unit 28 of the security device 10 repeatedly executes the security process shown in FIG. 4 every predetermined time. In the initial state (the state immediately before step S100), the description will be made assuming that the security mode is the security release state.

  In the security device 10, it is determined whether or not the reception unit 42 has received an instruction to switch the security mode to the security state (step S100).

  When the switching instruction is not received (step S100: No), the security release state is maintained (step S104), and the process returns to step S100.

  On the other hand, when an instruction to switch to the security state is received (step S100: Yes), the process proceeds to step S102, and time measurement for a predetermined time is started (timer start). This is to prevent a person who has switched to the security state from being notified even if detected by the sensor before leaving the security area.

  Thereafter, the time is measured until the predetermined time elapses, and when the predetermined time elapses (step S106: Yes), the process proceeds to step S108 and the time measurement is terminated (step S108).

  Next, the first control unit 40 controls the security mode switching unit 34 so as to switch the security mode from the security release state to the security state (step S110). When the security mode is switched to the security state and a person is detected, an abnormality is detected. The signal shown can be reported to the monitoring center 14.

  If the person is detected by the sensor 20 installed in the security area after the security mode is switched to the security state (step S112: Yes), the process proceeds to step S118. If no person is detected (step S112: No), the process proceeds to step S114.

  In step S112, the reception unit 42 determines whether or not an instruction to switch from the security state to the security release state is received. If the instruction is received (step S114: Yes), the first control unit 40 guards the security mode. The security mode switching unit 34 is controlled to switch from the state to the security release state (step S116), and the process returns to step S100. If not received (step S114: No), the process returns to step S112.

  Since the person is detected by the sensor 20 after the security mode is switched to the security state, the first control unit 40 notifies the monitoring center 14 of an intruder detection signal that is a signal indicating intruder detection. The reporting unit 38 is controlled (step S118).

  Next, the collation unit 44 captures the captured person included in the captured image corresponding to the time when the person was detected in step S <b> 112, and the registered person stored in the storage unit 32. Collation is performed (step S124). At this time, when a plurality of captured persons are included in the captured image, collation is performed. The collation unit 44 considers the positional relationship between the sensor 20 that detects the person and the imaging unit corresponding to the sensor 20, the detection range, and the shooting range, before / after the time when the person is detected. What is necessary is just to select suitably, such as using the image of one or both, how many seconds worth of images are used.

  As a result of the collation, when there is a registered person stored in the storage unit 32 (step S126: Yes), the process proceeds to step S128. If there is no registered person, the process ends. In this case, based on the reception of the intruder detection signal, the monitoring center dispatches security guards to the monitoring area in order to confirm the status of the monitoring area where the abnormality is detected. Request the agency to dispatch.

  In step S128, since the registered person is detected as a result of the collation, it is determined that the person has been working overtime but has been switched to the security state (such as an erroneous operation), and the first control is performed. The unit 40 controls the security mode switching unit 34 to switch the security mode from the security state to the security release state.

  Next, the first control unit 40 controls the reporting unit 38 so as to report the registered person signal (step S130). In this case, after receiving the intruder detection signal, the monitoring center receives the registered person signal indicating that the detected person is the registrant. Therefore, it can be determined that the previous intruder detection signal was an error. Thereby, it is not necessary to dispatch the guard to the monitoring area, or the dispatch can be canceled. In addition, dispatch requests to related organizations such as the police are unnecessary or can be canceled.

  As described above, in the security device 10 according to the present embodiment, when a person is detected in the security area when the security mode is in the security state, an intruder detection signal is sent to the monitoring center 14 as a report indicating an abnormality. report. Further, in the security device 10, if the imaged person included in the captured image captured by the imaging unit 18 that images the security area at this time is a registered person who has been registered, it is registered as a notification indicating normality. The person signal is reported to the monitoring center 14. In this case, the security device 10 switches the security mode from the security state to the security release state.

  As described above, in the security device 10 according to the present embodiment, when the person detected in the security area is a registered person when the security mode is in the security state, the security staff is directed to the security area. The registered person signal that does not require any security processing based on the notification in the monitoring center 14 such as reporting to a related organization can be reported to the monitoring center 14.

  Therefore, in the security device 10 of the present embodiment, the security burden can be suppressed.

  Here, an operation for switching to the security state from step S100 to step S110, which has been conventionally performed based on a human operation, was attempted by a system that automatically switches to the security state as described in Patent Document 2. In this case, a large number of sensors had to be installed in order to detect a person in the security area without omission. In addition, it is assumed that a blind spot in the detection area is caused by a locker or a vertical door that exists in the security area, and there is a possibility that even if there is a person in the security area due to omission of detection, there is a possibility of switching to the security state due to an erroneous determination. there were. Therefore, it was difficult to introduce unless the environment was ideal or limited.

  On the other hand, in the security device 10 of the present embodiment, when the person detected in the security area is a registered person when the security mode is the security state, the registered person signal is notified to the monitoring center 14. To do. Therefore, in the case of an artificial mistake that switches to the security state despite the presence of a person in the security area, or an erroneous determination in the case of switching to the security state automatically by the technique described in Patent Document 2. Even in this case, it can be confirmed that the registered person is detected, and the security device 10 of the present embodiment can effectively suppress the security burden with a simple configuration.

  Moreover, what is necessary is just to utilize the captured image imaged by the imaging part 18 which image | photographs the inside of a guard area as the captured image used for collation by the collation part 44. FIG. Thereby, the number and cost which install an imaging part (monitoring camera) separately can be reduced.

<Modification>
In the above, the person to be captured included in the captured image captured by the imaging unit 18 corresponding to the time when the person is detected in the security area when the security mode is the security state. The case where the registered person stored in the storage unit 32 is compared with the registered person has been described.

  However, in the above example, when the person existing in the security area is not facing the image capturing unit 18, collation by face authentication cannot be performed. Therefore, when a person is detected in the security area when the security mode is in the security state, the security device 10 notifies a message that prompts the person existing in the security area to be imaged by the imaging unit 18. Thereafter, the verification unit 44 may perform authentication using the captured image captured by the imaging unit 18.

  Next, when performing such collation, the procedure different from FIG. 4 of the security process performed by the security device 10 will be specifically described. FIG. 5 is a flowchart showing a procedure of security processing different from that shown in FIG. 4 executed by the security device 10 according to the present embodiment.

  The control unit 28 of the security device 10 repeatedly executes the security process shown in FIG. 5 every predetermined time. In the initial state (the state immediately before step S200), the security mode is described as being in the security release state.

  In the security device 10, the process of step S200-step S218 is performed similarly to step S100-step S118 of FIG. As a result, the security device 10 transmits an intruder detection signal to the monitoring center 14 when a person is detected in the security area when the security mode is in the security state.

  Next, the 1st control part 40 controls the alerting | reporting part 24 so that guidance information may be output (step S220). Specifically, the first control unit 40 prompts the user to move to a position where the image can be captured by the imaging unit 18 corresponding to the sensor 20 that detected the person in step S212, or to turn his face toward the imaging unit 18. Is output as guidance information.

  Specifically, the first control unit 40 refers to the identification information of the sensor 20 that detected the person in step S212. The correspondence between the sensor 20 and the imaging unit 18 is determined in advance and stored in the storage unit 32 as a reference table. By referring to this reference table, the imaging unit 18 corresponding to the sensor 20 is specified. Then, the first control unit 40 generates a message that prompts the user to move to a position where the identified image capturing unit 18 can capture an image or turn the face toward the image capturing unit 18, and output the message as guidance information. The unit 24 is controlled.

  By the processing in step S220, information indicating guidance to the imaging unit 18 that images the detection area of the sensor 20 that has detected a person existing in the security area is notified from the notification unit 24 to the security area by voice or the like. .

  Instead of sending a voice message, the face is directed toward the imaging unit 18 by turning on a rotating lamp or a display lamp provided in the vicinity of the imaging unit 18 specified by the process of step S220. Also good. In this case, if a rotating lamp or an indicator lamp is lit in advance for a registered person, it is possible to perform face authentication more reliably if it is known that the face is directed toward the imaging unit 18 in the vicinity thereof. it can.

  Next, the first control unit 40 controls the imaging unit 18 to perform imaging with the imaging unit 18 identified in step S220 (step S222). The first control unit 40 controls the imaging unit 18 by outputting an imaging instruction to the identified imaging unit 18. At this time, imaging is performed for a predetermined time so that a person existing in the security area is photographed with certainty.

  Next, the collation unit 44 collates the captured person included in the captured image captured by the imaging unit 18 by the process of step S222 and the registered person stored in the storage unit 32 (step S224). Next, the collation unit 44 determines whether or not all the captured persons included in the captured image are registered persons registered in the storage unit 32 (step S126 in FIG. 4) (step S126). S226).

  Next, in the security device 10, the processing of step S228 to step S230 is performed in the same manner as in step S128 to step S130 of FIG. 4, and this routine is terminated.

  Note that a negative determination is made in step S226 (step S226: No), that is, if the registered person is not included in all the captured persons included in the captured image, the process returns to step S220 and the guidance information is output again. Good. Then, even if the guidance information output, imaging, collation, and determination process of whether or not the person is a registered person in steps S220 to S226 are repeated for a predetermined time or a predetermined number of times, The routine may be terminated.

  As described above, in the security device 10, when a person is detected in the security area when the security mode is the security state, a message that prompts the person existing in the security area to be imaged by the imaging unit 18. The verification unit 44 may perform authentication using the captured image captured by the imaging unit 18 during the notification.

  In the above-described embodiment, the collation unit 44 has been described as performing collation using the captured image captured by the imaging unit 18, but when a monitoring camera or the like is separately installed in the monitoring area. Alternatively, verification may be performed using a captured image acquired by the monitoring camera.

  Further, in the above-described embodiment, the case where the security device 10 collates the captured person included in the captured image with the registered person using the collation unit 44 provided in the security device 10 has been described. However, an external device including the imaging unit 18, the collation unit 44, and the storage unit 32 may be prepared, and only the collation result between the imaged person and the registered person may be received from the external device. Specifically, when there is a face authentication device used for entrance / exit management, face authentication may be performed by the face authentication device and the result may be transmitted to the security device 10. The external device is connected to the security device 10 via the network 12.

  In this case, the security device 10 transmits an intruder detection signal to the monitoring center 14 when a person is detected in the security area after the elapsed time after switching to the security state exceeds the holding time. A signal indicating a verification request may be transmitted to the external device. Then, in the external device that has received the verification request, the verification unit 44 in the external device performs verification between the captured person included in the captured image and the registered person, and as a verification result, all of the captured persons included in the captured image are registered. Information indicating that the captured person included in the captured image includes a person other than the registered person may be transmitted to the security device 10. And in the security device 10 which received the collation result, what is necessary is just to perform the process of step S228-step S230 mentioned above.

  The security device 10 according to the present embodiment described above includes a control device such as a CPU, a storage device such as a ROM and a RAM, an external storage device such as an HDD and a CD drive device, a display device such as a display device, It has an input device such as a keyboard and a mouse, and has a hardware configuration using a normal computer.
