JP 2008-146401 A

  In the grounds of buildings such as single-family gardens, visitors such as visitors and delivery companies other than suspicious individuals enter and exit. If the security system detects these persons and reports them uniformly to the monitoring center, unnecessary notifications increase, resulting in an increase in security costs. Therefore, it is conceivable that the user of the security system once confirms the image on the indoor monitor and then reports to the monitoring center as necessary.

However, it is not always possible for the user to check the presence or absence of an abnormality with an image or the like and determine whether or not a report is necessary. For example, there is a case where only a young child can be supported. In such a case, if you leave the abnormal report to the monitoring center etc. to the user's judgment, the report will not be sent to the monitoring center despite the intrusion of the suspicious person, or the damage will be delayed. There is a risk.
Therefore, an object of the present invention is to provide a security system that can appropriately report an abnormality according to a user's situation when entry into a monitoring area is detected.

  In order to achieve the above object, a security system according to the present invention includes a sensor terminal that monitors entry into a monitoring area around a building, and a notification terminal that notifies a user of detection information acquired by the sensor terminal. The notification terminal includes a display unit that displays detection information received from the sensor terminal, and an operation unit that inputs a notification operation by a user, and the sensor terminal is provided in the monitoring area. By a detection unit that detects an intruding person, an identification unit that identifies whether the person is the user, a storage unit that stores the attributes of the user residing in a building, and a non-user When an intrusion into the monitoring area is detected, based on the attribute of the user residing in the building, a first alarm process for transmitting the detection information to an external monitoring center or the detection information is transmitted to the notification terminal Shi Characterized by comprising the a monitoring control unit for selectively executing a second warning process of transmitting the detection information to the monitoring center when receiving the notification operation.

  According to this configuration, when a person other than the user enters the monitoring area, it is possible to execute an appropriate alarm process according to the attribute of the user residing in the building. User attribute is an indicator that confirms whether or not an intruder is a suspicious person based on the contents of notification and the situation at the site, and directly or indirectly indicates whether or not notification is necessary and can be performed. It is. In other words, if a user with the ability to confirm a suspicious person is present, unnecessary notifications are suppressed by reporting to the monitoring center after confirming the user, and there are users who do not have the confirmation ability. When you are in the house, you can ensure the safety of the users who are living by checking the suspicious person directly at the monitoring center and taking action. In this way, by executing different alarm processing depending on the resident attributes, it is possible to realize a security system that is highly convenient and highly safe.

In the above configuration, the detection unit detects the position of a person in the monitoring area, and the monitoring control unit detects the intrusion by a person other than the user from outside the site outside the monitoring area. The first or second alarm process is executed.
According to this configuration, by limiting the target of alarm processing to entry from outside the site, it is possible to prevent alarms from being made to people who have exited the building that are not unauthorized intrusions, and appropriate intrusion monitoring can be performed. realizable.

Further, in the above configuration, the storage unit stores presence / absence information that is updated according to the user's entry / exit, and the monitoring control unit allows the user to enter the building from outside the site through a monitoring area. If it moves, it will determine with an entrance, and if the said user moves out of a site via a monitoring area from a building, it will determine with an exit, and the said presence / absence information is updated.
According to this configuration, it is possible to manage whether or not the user is resident using the person detection information and the user identification information. In addition, since the presence / absence information of the user can be managed without requiring any special operation by the user, a highly convenient security system can be realized.

  Further, in the security system having the above configuration, when the monitoring control unit detects an intrusion into the monitoring area by a person other than the user, the first alarm process is executed when there is no resident user. It is preferable to do this. With this configuration, when the user cannot be confirmed due to the absence, the monitoring center can appropriately cope with it.

  In the security system having the above-described configuration, the sensor terminal is further provided with an imaging unit that captures an image of a monitoring area and acquires an image, and the monitoring control unit transmits the detection information including an image acquired by the imaging unit to the notification terminal. It is also preferable to transmit to the monitoring center.

  Further, in the security system having the above configuration, the sensor terminal further includes a voice output unit that outputs the voice received from the monitoring center to the monitoring area, and a voice input unit that collects sound in the monitoring area. It is also preferable to be able to form a voice call with the notification terminal or the monitoring center.

  In order to achieve the above object, a sensor terminal of the present invention includes a sensor terminal that monitors entry into a monitoring area around a building, and a notification terminal that displays detection information acquired by the sensor terminal and notifies the user of entry. A sensor terminal for use in a security system, a detection unit for detecting a person who has entered the monitoring area, an identification unit for identifying whether or not the person is the user, A storage unit for storing the attributes of the user who resides, and when detecting an entry into the monitoring area by a person other than the user, the detection information is sent to an external monitoring center based on the attributes of the user residing in a building. A second alarm for transmitting the detection information to the monitoring center when receiving a user's notification operation via the notification terminal after transmitting the detection information to the notification terminal Processing Characterized by comprising a monitoring control unit that executes the 択的, the.

  According to the present invention, it is possible to appropriately select alarm processing based on user confirmation and alarm processing based on monitoring center confirmation according to the user who is resident, and to provide a security system that combines convenience and safety. it can.

It is the figure which showed typically the operation image of the security system of this embodiment. It is a functional block diagram which shows schematic structure of a sensor terminal. It is a figure which shows an example of user management information. It is a flowchart which shows the monitoring process at the time of a human body detection. It is a flowchart which shows the monitoring process at the time of a human body detection.

  Hereinafter, a preferred embodiment of a security system according to the present invention will be described in detail with reference to the drawings, taking as an example a security system that targets a detached dwelling unit and detects an intruder into a dwelling yard.

First, the configuration and operation of the security system of this embodiment will be schematically described. FIG. 1 is a diagram schematically showing an operation image of the security system according to the present embodiment.
The security system uses the site (garden part) on the outer periphery of the building as the monitoring area 3, and notifies the sensor terminal 1 that monitors intrusion from outside the site and the users in the house of the occurrence of intruders in the garden part. It is comprised including the alerting | reporting terminal 2 to perform. A plurality of sensor terminals 1 are arranged at appropriate outdoor locations so as to cover the garden part which is the monitoring area 3. The notification terminal 2 is provided in any place in the house, for example, in the living room. Two or more notification terminals 2 may be provided, and may be a portable terminal that can be carried instead of fixed installation.

  When the sensor terminal 1 detects an intrusion action into the monitoring area 3, the sensor terminal 1 transmits a captured image at the time of detection together with the detection information to the notification terminal 2. The notification terminal 2 that has received the detection information and the image notifies the user at home that an intruder has occurred and displays the received image to prompt the user to confirm. The user checks the displayed image, and performs a notification operation when it is confirmed that the person who entered the site is a suspicious person. When the sensor terminal 1 detects the user's notification operation via the notification terminal 2, the sensor terminal 1 issues an abnormality notification to an external monitoring center via the communication network. At this time, the image at the time of detection is transmitted and the current photographed image and sound are transmitted in real time, so that the monitoring center can grasp the situation of the site where the abnormality has occurred. When there is no user who is at home, the user is immediately notified to the monitoring center without requiring the user to perform a reporting operation. At the monitoring center that has received the abnormal report, the controller will respond to the intruder while checking the image and sound, warn to stop the crime through the sensor terminal 1, and to the guards and police who are waiting nearby Request a response, grasp the on-site situation, and take a prompt and appropriate response.

  Even if the user is at home, there is a possibility that the intrusion notification at the notification terminal 2 cannot be appropriately handled when the home user is a user with low judgment ability such as a young child. In other words, even if the image is confirmed, it may be impossible to correctly determine whether or not the person is a suspicious person, or the abnormality reporting operation itself may not be recognized. Therefore, in this security system, confirmation authority information consisting of attributes such as the user's age is managed, and when only non-authorized persons are at home, an abnormal report is sent to the monitoring center without requiring the user's report operation. Check the situation at the center and enable quick and appropriate handling.

Hereinafter, a specific structure and operation | movement are demonstrated about the security system of this embodiment.
In addition to the sensor terminal 1 and the notification terminal 2 described above, the security system further includes a wireless tag possessed by the user and capable of identifying that the user is a resident (or a qualified person). The security system identifies whether or not the person entering the monitoring area 3 is a user by the wireless tag. Further, based on the entrance / exit of the user who owns the wireless tag, the user's home status and the attributes of the user at home are managed.

The wireless tag corresponds to a so-called RFID system responder, and when a query wave having a predetermined frequency is received, a response wave with its own identification code is transmitted.
The notification terminal 2 includes a wireless communication unit for wireless communication with the sensor terminal 1, a display unit for displaying images and sounds received from the sensor terminal 1, an operation unit for inputting a user's notification operation, And a notification control unit that controls each unit. The wireless communication unit is means for wirelessly communicating with the notification terminal 2 and other sensor terminals 1. For example, a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard represented by IEEE 802.11 can be used. The display unit includes a liquid crystal display and a speaker 108. The operation unit is realized by a button switch or an operation button displayed on the screen when the display unit is a touch panel display. The notification terminal 2 may be configured as a terminal dedicated to the security system, but may be configured integrally with the function of the interphone master so that it can be used in combination with a general interphone master.

FIG. 2 is a functional block diagram illustrating a schematic configuration of the sensor terminal 1.
The sensor terminal 1 includes a sensor 100, a tag reader 102, a camera 104, a microphone 106, a speaker 108, a home wireless communication unit 110, a public wireless communication unit 112, a battery 114, a storage unit 116, and a monitoring control unit.

  The sensor 100 detects a human body that has entered the monitoring area 3. For example, the scanning area 3 is configured by a laser distance measuring sensor that executes laser scanning at a predetermined cycle and can specify the presence and position of a human body according to the magnitude, angle, and distance of the change in distance. The sensor 100 is not limited to a laser distance measuring sensor. Various sensors 100 that can detect a human body and its position, such as a microwave sensor that detects a change in a reflected wave of a microwave, and an image sensor that detects an image change. Applicable.

  The tag reader 102 detects a wireless tag possessed by the user in the detection area. It corresponds to an interrogator of a so-called RFID system, transmits an interrogation wave to a detection area, receives a response wave from the radio tag, and reads an identification code given to the radio tag. The tag reader 102 may be driven constantly or periodically, and may be driven at a timing based on an instruction from the control unit. Here, the security system uses the detection information of the sensor 100 and the detection information of the tag reader 102 to determine whether the person entering the monitoring area 3 is a user. The detection area is set to be approximately the same.

The camera 104 acquires an image or video at a predetermined frame rate with the range including the monitoring area 3 of the sensor 100 as an imaging angle of view.
The microphone 106 is means for collecting sound generated in the monitoring area 3.
The speaker 108 is a means for generating a warning sound or sound for the monitoring area 3. Based on the control of the monitoring control unit, a warning sound such as a buzzer or warning guidance for an intruder or a voice received from the monitoring center is output.

The in-home wireless communication unit 110 is means for wirelessly communicating with the notification terminal 2 and other sensor terminals 1. For example, it comprises a communication module that complies with a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard typified by IEEE 802.11.
The public wireless communication unit 112 is means for performing wireless communication with an external monitoring center via a public network. It is desirable that an image can be transmitted to the monitoring center in real time, and for example, a communication module conforming to a high-speed wireless communication standard represented by Wimax (registered trademark) or XGP (registered trademark) is used.
The battery 114 is means for supplying operating power to the monitoring control unit. A commercial power source may be used as the power supply means, or a commercial power source and a battery may be used in combination.

  The storage unit 116 stores various programs for operating the sensor terminal 1 and stores user management information, accumulated images, and area map information in an updatable manner. FIG. 3 shows an example of user management information. The user management information includes the identification code of the wireless tag possessed by the user, the user's attributes, that is, the confirmation authority information indicating the presence or absence of confirmation authority for determining whether or not the user is suspicious, presence / absence indicating whether the user is at home It is data in which information is associated with each other and is updated as needed by the monitoring control unit. Here, the presence / absence of the confirmation authority is directly set as the user's attribute. However, the present invention is not limited to this, and the confirmation authority may be separated at a predetermined age by associating the age as the user's attribute. A relationship (father, mother, eldest son, second son, grandfather, etc.) may be associated with each other and confirmation authority may be set separately for the second son and grandfather. The accumulated image is a data area in which an image captured by the camera 104 can be recorded for a predetermined time, and is recorded and controlled by the monitoring control unit. The area map information is information representing the actual layout of the monitored building or garden and the positional relationship between the monitored area 3 and the boundary between the monitored building and the monitored area 3, the area outside the site, and the monitored area. The boundary with area 3 is shown.

The monitoring control unit is configured by an MPU or the like, and has a function of performing overall control of each unit.
The monitoring control unit detects a human body that has entered the monitoring area 3 based on the detection signal input from the sensor 100 and tracks the movement of the human body. The supervisory control unit refers to the area map information in the storage unit 116 and recognizes that the appearance point of the human body is a human body that has entered from the outside when the appearance point of the human body is on the boundary side with the outside of the site, and the building control unit on the boundary side with the building Recognize that it is a human body that came from within. Conversely, when the tracked human body disappears, if the disappearance point is on the boundary side with the outside of the site, it is recognized as exiting outside, and if it is on the boundary side with the building, it is recognized as entering the building. .

  When the monitoring control unit detects the human body, it drives the tag reader 102 to read the wireless tag in the monitoring area 3 and refers to the user management information in the storage unit 116 to determine whether the detected human body is a user. To do. The monitoring control unit updates the user management information based on the presence / absence of the wireless tag and the entrance / exit by moving body tracking. When it is recognized that the user has entered the building, the presence / absence information corresponding to the detected tag identification code is updated to “at home”. When it is recognized that the user has left, the corresponding presence / absence information is updated to “going out”.

  In addition, when the detected human body is not a user but a suspicious person, the monitoring control unit stores an input image from the camera 104 as an accumulated image in the storage unit 116 until the human body disappears from the monitoring area 3. Record.

  In addition, when there is a possibility that the detected human body is a suspicious person, the monitoring control unit refers to the user management information and executes different alarm processing based on the presence / absence information and the confirmation authority information. There is a person who is in the home (there is a user whose presence / absence information is “at home”) and has a confirmation authority (there is a user who has confirmation authority information in the “at-home” user) ), The input image from the camera 104 and the input sound from the microphone 106 are transmitted to the notification terminal 2 through the home wireless communication unit 110 together with the detection information. Then, when a notification operation signal resulting from the notification operation by the user is received from the notification terminal 2, the current input image and input voice are transmitted to the monitoring center in real time via the public wireless communication unit 112. Further, in response to an instruction command from the monitoring center, the stored image recorded in the storage unit 116 is transmitted to the monitoring center.

  On the other hand, there are no resident people (all users' presence / absence information is “going out”), or there are resident people and there are no resident people with confirmation authority (use of “at home”) If all the confirmation authority information of the person is “nothing”), there is only a child or the like, and it is necessary to deal directly with the monitoring center. The current input image and input sound are transmitted to the monitoring center in real time via the wireless communication unit 112. When the resident is present, the detection information is transmitted to the notification terminal 2 via the home wireless communication unit 110 to notify the resident of the presence of the intruder.

Next, the flow of processing executed by the monitoring control unit when an intruder appears in the monitoring area 3 will be described with reference to FIGS. 4 and 5.
4 and 5 are flowcharts showing a monitoring process at the time of detecting a human body. When the monitoring control unit detects a person (human body) in the monitoring area 3 based on the detection signal input from the sensor 100, the monitoring control unit executes the following monitoring process.

  The monitoring control unit starts tracking a person who appears in the monitoring area 3 (step 202), and determines whether the tag reader 102 has detected a wireless tag (step 204). If there is a wireless tag in monitoring area 3, it is recognized as a legitimate user, and the subsequent process recognizes entry / exit from the user's movement and manages the presence / absence of the user (shift to A) .

  Based on the position of the appearance point of the person who is the user, the monitoring control unit determines whether the entry is from the outside of the site to the monitoring area 3 or the entry from the building to the monitoring area 3 (step 302). . In the case of entering from outside the site, the tracking is continued until the person disappears from the monitoring area 3 (step 304). When the person disappears, the person leaves the site based on the position of the disappearance point or inside the building. It is determined whether or not to enter (step 306). If it is determined that the user has entered the building, the user has returned home, so the presence / absence information of the user management information corresponding to the read identification code of the wireless tag is updated to “at home” and the monitoring process is terminated. (Step 308). If it is determined that the user has left the site, the user has once entered the site but has not entered the building and has left the site again. Therefore, the user management information is not updated, and the process ends.

  Also, when it is determined that the person who is the user has entered the monitoring area 3 from the building (No in Step 302), the tracking is continued until the person disappears from the monitoring area 3 in the same manner. (Step 310) Based on the position of the vanishing point, it is determined whether to leave the premises or enter the building (Step 312). If it is determined that the user has left the site, the user has gone out, so the presence / absence information in the user management information corresponding to the read identification code of the wireless tag is updated to “out” and the monitoring process is terminated. (Step 314). If it is determined that the user has entered the building, the user once exits the building but does not go out of the premises but enters the building again, so the processing ends without updating the user management information.

  On the other hand, if the wireless tag cannot be detected in the monitoring area 3 (No in step 204), the detected person is recognized as a person other than the user, and subsequently monitored from outside the site based on the position of the detected appearance point of the person. It is determined whether the entry is to the area 3 or the entry to the monitoring area 3 from the building (step 206). In the case of entering from a building, it is not at least an intruding action by a suspicious person, but for example, when a user forgets to carry a wireless tag and comes out of the building. A voice guidance is output (step 208). In the case of entering from outside the site, there is a possibility that a person who entered the monitoring area 3 is a suspicious person who intends to enter the building and a non-malicious visitor such as a delivery person or acquaintance of delivery. Therefore, recording of the photographed image by the camera 104 is started, and whether or not the person is a suspicious person is checked according to the user's home situation.

  First, the monitoring control unit refers to the user management information and confirms whether there is a resident in the building (step 210). When there are no resident persons, that is, when the presence / absence information of all users is “going out”, since the user cannot confirm the person who entered the site, the captured image and acquired audio data are sent to the monitoring center. Transmit (step 212). The monitoring center performs real-time processing of images and sounds sent from the site, and monitors whether the detected person moves suspiciously. The supervisory control unit outputs a warning message from the speaker 108 when the person stays in the site for a predetermined time or more (step 214). Also, audio data received from the monitoring center is output from the speaker 108.

  If there is a resident (Yes in Step 210), the attribute of the resident is confirmed, and it is determined whether or not the user having the confirmation authority is at home (Step 216). If there is even one person with confirmation authority (Yes in Step 216), the captured image and acquired voice data are transmitted to the notification terminal 2 in the house and displayed on the notification terminal 2 (Step 218). The user confirms whether the person who entered the site is a suspicious person or a visitor such as an acquaintance by the image and sound displayed on the notification terminal 2, and when the user recognizes the person as a suspicious person, Operate the notification button. When the notification button is operated, the notification terminal 2 transmits a notification operation signal to the sensor terminal 1. After transmitting the notification data to the notification terminal 2, the monitoring control unit waits for reception of a notification operation signal from the notification terminal 2 (step 220). The reporting operation is continuously monitored for a certain period of time or until the person who has entered the field leaves the monitoring area 3 outside the site. When the notification operation signal is received (Yes in Step 220), since it is confirmed that the user is a suspicious person or a suspicious person, the image and audio data are transmitted to the monitoring center, A warning message is output from the speaker 108 to warn the suspicious person to stop the crime (steps 212 to 214). Also, when audio data is received from the monitoring center, audio is output via the speaker 108. If the reporting operation has not been performed (No in step 220), since the user has confirmed that he / she is not a suspicious person, the monitoring process is terminated without reporting or warning to the monitoring center.

  On the other hand, when only a user who does not have confirmation authority is at home (No in step 216), there is a possibility that the user will not be notified despite the presence of the person at home. The intrusion notification is transmitted by transmitting the data (step 222), and the captured image data and the acquired voice data are immediately transmitted to the monitoring center, and a warning is given from the speaker 108 as necessary (steps 212 to 214). As a result, the monitoring center can perform real-time processing of images and sounds sent from the site and monitor whether or not the detected person moves suspiciously.

  As described above, the security system according to the present embodiment automatically manages entry / exit of a user without requiring a special operation, and detects an approaching action to a monitoring area around the building, Different alarm processing is executed according to the home status of the user and the attributes of the home user. Specifically, if there is a user who has a confirmation capability in the house, the user is requested to confirm the suspicious person, and if not, the monitoring center confirms the suspicious person. Thereby, it is possible to appropriately cope with the act of entering the monitoring area according to the user's occupancy status.

  In the security system of the above embodiment, an operation unit for a user to perform a notification operation is provided in the notification terminal, but a notification button may be provided in the wireless tag. In this case, the wireless tag is configured to transmit a notification operation signal triggered by pressing of the notification button, and configured to receive the notification operation signal by a tag reader of the sensor terminal.

  In the security system of the above embodiment, when there is a home person having a confirmation authority, a notification operation is performed by the user to the monitoring center, but the cancel operation is not performed for a predetermined time. It can also be set as the structure reported in case. In this case, a cancel button is provided together with a report button, and when an intruder from the outside is detected, the report button is operated or when the cancel button is not operated within a predetermined time, a notification is sent to the monitoring center. And

  In the security system of the above embodiment, when configured using a plurality of sensor terminals, only one representative sensor terminal is provided with a monitoring processing function by the public wireless communication unit or the above-described monitoring control unit, and other sensors. The terminal may be configured to transmit input information from a sensor, a tag, or the like to a representative sensor terminal.

  Moreover, in the security system of the said embodiment, although it was set as the structure which provides a monitoring processing function and a communication function with a monitoring center in a sensor terminal, you may provide all or one part in a notification terminal in a house. In this case, the notification terminal is provided with a monitoring processing function by a public wireless communication unit or a monitoring control unit, and the sensor terminal is configured to transmit input information from a sensor, a tag, or the like to the notification terminal.

  In addition, the security system of the above embodiment realizes a security system that does not require any special operation by using a wireless tag to determine whether a person existing in the monitoring area is a user. However, it can be replaced by another configuration that can obtain the same effect. For example, as means for identifying a user, biometric authentication (biometric authentication) technology such as face authentication or iris authentication can be applied. By realizing biometric authentication by image processing, the sensor, tag reader, and camera can be replaced by an image sensor in the configuration of the sensor terminal of the above embodiment.

  In the security system of the above embodiment, the presence / absence information is managed based on the entrance / exit of the user who owns the wireless tag. However, the tag reader for detecting the wireless tag in the building is provided, User presence / absence information can also be managed based on the presence / absence of a wireless tag.
