Description

  The present invention relates to a security system that detects intrusion of a suspicious person into a garden of a house and checks detection information by a resident at home or an external monitoring center.

  Conventionally, a security system has been provided in which various sensors are arranged in a monitored building such as a detached house, an intruder into the building is detected, and an abnormality is reported to a monitoring center or the like. There has also been proposed a monitoring system that monitors a garden of a building with a sensor, detects an intruder outdoors before entering the building, and alerts early.

  For example, Patent Document 1 discloses a constant security system that transmits alarm information indicating that an abnormality has been detected to a monitoring center connected to the Internet when an abnormality in a detached garden is detected. In this system, when the crime prevention mode is set, the presence of a person is monitored by a human sensor installed at the entrance of the garden. When the stay of the human body is detected over a predetermined time, alarm information indicating that an abnormality has been detected is output. Also, the video data captured by the monitoring camera is output to the indoor monitor and the monitoring center monitor.

JP 2008-146401 A

In a detached house, one side of the building may face a common area such as a road. If a road is monitored, an alarm is output every time a passerby is detected and an abnormality check is required, so it is difficult to monitor the adjacent road adjacent to the building.
However, if there is a window in the part of the building facing the road, the possibility of becoming an intrusion route or a peephole cannot be excluded. For example, when the bathroom faces the road, it is uncomfortable for the user to have a person sitting in the vicinity while taking a bath.

  Therefore, an object of the present invention is to provide a security system that can be automatically monitored only when a user needs monitoring even in a common area such as a road facing a building.

  In order to achieve the above object, the security system of the present invention is a security system in which a suspicious person is detected and abnormally detected in a monitoring area consisting of at least a regular monitoring area and a semi-monitoring area set around a building, and enters the monitoring area. A detection unit for detecting a person who has performed the operation, an identification unit for identifying whether or not the person is a user, an action monitoring unit for monitoring a behavior state of the user in a building, and the residence in the building A storage unit that stores a behavior state of a user, and a monitoring control unit that determines an abnormality upon detecting an intruder other than the user entering the monitoring area, and normally monitors the normal monitoring area in the monitoring area And a monitoring control unit that puts the semi-monitoring area into a monitoring state together with the regular monitoring area when the user is in a specific action state.

  According to such a configuration, even if a monitoring area including an area (semi-monitoring area) where a general person passes such as a public road is set, the semi-monitoring area is set according to the behavior state of the user residing in the building. Automatically sets whether or not monitoring is necessary. For this reason, it is possible to detect a suspicious person as necessary while suppressing an abnormality determination due to the passage of a general person, and an appropriate alarm can be given. The user's action state is an index for determining whether or not to set the semi-monitoring area that is normally in the non-monitoring state to the monitoring state. For example, if a public road facing the window side of a bathroom is set as a semi-monitoring area and the user is in a specific behavioral state of bathing, the semi-monitoring area should be set to detect a suspicious person's peeping action and determine an abnormality. Set the monitoring status. Thus, since a specific monitoring area is monitored according to the resident's behavior state, it is possible to realize a highly secure security system without impairing convenience during normal times.

Moreover, the said structure WHEREIN: The said action monitoring part determines the said action state of the said user based on the position where the said user exists in a building at least.
According to such a configuration, it is possible to determine whether or not the user is in an action state that requires monitoring of the semi-monitoring area, depending on which section in the building the user is in.

In the above configuration, the storage unit stores each of the plurality of specific behavior states in association with any of the plurality of semi-monitoring areas, and the monitoring control unit is configured so that the user has a specific behavior state. The semi-monitoring area corresponding to the specific action state is set to the monitoring state.
According to such a configuration, an area that requires monitoring can be set to a monitoring state according to each action state.

In the above configuration, the monitoring control unit determines the abnormality when intrusion other than the user is continuously detected for a predetermined time in the semi-monitoring area in the monitoring state.
According to such a configuration, even when the semi-monitoring area is monitored, it is possible to prevent a general passerby from being determined as a suspicious person.

Further, in the above configuration, further comprising a notification terminal having a display unit for notifying a user in the building of detection information by the detection unit and an operation unit for inputting an emergency operation,
When the monitoring control unit detects an intrusion other than a user in the regular monitoring area, if there is no user residing in the building, the monitoring control unit determines that the abnormality is present, and there is a user residing in the building. In this case, the abnormality is determined when the detection information is notified at the notification terminal and the emergency operation is input.
According to such a configuration, when there is a person at home when detecting an entry action to the regular monitoring area, an abnormality is determined as a suspicious person by mistake because the abnormality is determined after confirmation by the person at home. Can be prevented.

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. Good.
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 good to use for the display in and the report 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. Then, it is preferable that a voice call can be formed between the notification terminal and the monitoring center.

  According to the present invention, an area that is not monitored in a normal state is temporarily monitored in accordance with the behavior of a user who is resident. Therefore, it is possible to provide a security system that has both convenience and safety.

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. 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 is configured to include a sensor terminal 1 that monitors a suspicious person with the outer periphery of the building as a monitoring area, and a notification terminal 2 that notifies a user in the house of the presence of the suspicious person. A plurality of sensor terminals 1 are arranged at appropriate locations outside the monitoring area so as to cover the regular monitoring area 3 corresponding to the garden portion of the site. The sensor terminal 1 includes a public road outside the site facing a specific room as a semi-monitoring area 5 in the monitoring area. For example, as shown in FIG. 1, the semi-monitoring area 5 is set in a public road area outside the site facing the bathroom window in order to monitor the act of looking into the bathroom from outside the site when one side of the building is adjacent to the public road. To do. 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.

  The sensor terminal 1 is in a constant monitoring state for the normal monitoring area 3 in the monitoring area, and transmits an image taken at the time of detection to the notification terminal 2 together with the detection information when detecting an intrusion into the normal monitoring area 3. 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.

  The sensor terminal 1 is normally in a non-monitoring state for the semi-monitoring area 5 set on the public road outside the site. The behavior state is managed by monitoring the whereabouts and movements of the user who is at home, and is temporarily set to the monitoring state only when the user is in a specific behavior state such as bathing. When a suspicious activity such as peeping is detected in the semi-monitoring area 5 being monitored, the detection information and image are reported to the monitoring center as an abnormality, and the situation is confirmed at the monitoring center so that it can be dealt with promptly and appropriately.

Hereinafter, a specific configuration and operation of the security system of the present embodiment will be described with reference to FIGS. 1 to 6.
In addition to the sensor terminal 1 and the notification terminal 2 described above, the security system further includes a wireless tag that the user possesses and can be identified as a resident (or a qualified person) of the dwelling unit, An internal reader 4 for grasping the behavior state is included. The security system identifies whether or not the person entering the monitoring area is a user by the wireless tag. In addition, based on the entry / exit of the user who owns the wireless tag and the location and movement of the user in the home, the home status of the user and the behavior state 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 can use, for example, a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard typified by IEEE 802.11. 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.

  The internal reader 4 includes a wireless communication unit for wireless communication with the sensor terminal 1 and a tag reader for detecting a wireless tag possessed by the user as a detection area. The wireless communication unit includes a communication module that conforms to a short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN standard represented by IEEE 802.11, for example. The tag reader corresponds to a so-called RFID system interrogator, transmits an interrogation wave to the detection area, receives a response wave from the radio tag, and reads an identification code given to the radio tag.

  The internal reader 4 is provided for each of a plurality of partial areas obtained by dividing the entire residential area, and the internal reader 4 installed in each partial area detects a wireless tag using the partial area as a detection area. The partial area is arbitrarily set according to the layout in the building, and for example, is set as an area unit partitioned by a wall or a door. In the example of FIG. 1, each of “entrance”, “corridor”, “WC”, “living room”, “bathroom”, and “bedroom” is a partial area. The internal reader 4 transmits the identification code of the wireless tag read by the tag reader to the sensor terminal 1 together with its own identification code. Alternatively, the response wave from the wireless tag may be transmitted with the received intensity.

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 118.

  The sensor 100 detects a human body that has entered the monitoring area. 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 118, 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, another sensor terminal 1, and the internal reader 4. 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 118. 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 is data that associates an identification code (tag ID) of a wireless tag possessed by the user, presence / absence information indicating whether the user is at home or going out, and an action state of the user at home. Yes, updated by the monitoring controller 118 as needed. The user's behavior state is status information for determining whether or not the user at home can immediately respond to the notification terminal 2, for example, “living room” indicating that he / she is in the living room, There is a status indicating the user's whereabouts such as “toilet” indicating presence, and a status indicating the user's behavior such as “sleeping” and “taking a bath”.

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 118.
The area map information is information representing the positional relationship between the actual layout of the building or garden to be monitored and the monitoring area. Further, the positions of the normal monitoring area 3 and the semi-monitoring area 5 constituting the monitoring area are shown. The area map information indicates the boundary between the monitoring target building and the monitoring area, and the outer boundary of the monitoring area. The area map information includes information representing the correspondence between each partial area constituting the residential area and the identification code of the internal reader 4 using the partial area as a detection area.

The monitoring control unit 118 is configured with an MPU or the like, and has a function of performing overall control of each unit.
The monitoring control unit 118 acquires the identification code of the wireless tag and the identification code of the internal reader read by the internal reader 4 via the home wireless communication unit 110, and updates the user management information. The behavior state corresponding to the acquired identification code of the wireless tag is referred to, and when the transmission source internal reader 4 is different from the partial area, the current behavior state is overwritten and updated. For example, if a user whose behavioral state is “living room” receives information indicating that the wireless tag has been detected from the internal reader 4 installed in the “corridor”, this indicates that the behavioral state is at the entrance. Change to “Corridor”. Also, the type of behavior state is not limited to whereabouts, but includes user behavior such as “during bathing”. For example, when the user has stopped in the bathroom for a certain period of time, the behavioral state is updated not only by staying in the “bathroom” but also by “taking a bath”. Whether or not it is stopped is determined using a change in the intensity of the response wave by the wireless tag. If the intensity change is very small, it is recognized as being stopped within the partial area, and if the intensity change is greater than or equal to a predetermined value, it is recognized as moving within the partial area.

  The monitoring control unit 118 switches and sets the monitoring state of the monitoring area based on the user's action state. Of the monitoring areas, the regular monitoring area 3 is set to the regular monitoring state. On the other hand, the semi-monitoring area 5 is normally set to the non-monitoring state, and is set to the monitoring state when the user's behavior state is a specific behavior state. When a plurality of semi-monitoring areas 5 are set, each specific behavior state is associated with each regular monitoring area 5, and when the user is in a specific behavior state, the corresponding semi-monitoring area 5 is set to a non-monitoring state. Switch to monitoring state from.

The monitoring process in the regular monitoring area 3 will be described.
The monitoring control unit 118 detects a human body that has entered the regular monitoring area 3 based on the detection signal input from the sensor 100 and tracks the movement of the human body. The monitoring control unit 118 refers to the area map information in the storage unit 116, and recognizes that the appearance point of the human body is a boundary from the outside of the premises in the regular monitoring area 3 as a human body entered from the outside. In the case of the boundary side with the building of area 3, it recognizes that it is the human body which came out from the inside of a building. 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 118 detects a human body in the regular monitoring area 3, it drives the tag reader 102 to read the wireless tag in the regular monitoring area 3, refers to the user management information in the storage unit 116, and the detected human body is the user. It is determined whether or not. The monitoring control unit 118 updates the user management information based on the presence / absence of the wireless tag and the entry / exit by tracking the moving object. 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”.

  When there is a possibility that the detected human body is not a user but a suspicious person, the monitoring control unit 118 records an input image from the camera 104 as an accumulated image until the human body disappears from the monitoring area 3. To do.

When there is a possibility that the human body detected in the regular monitoring area 3 is a suspicious person, the monitoring control unit 118 refers to the user management information and executes different alarm processing based on the presence / absence information.
When there is a person at home (there is a user whose presence / absence information is “at home”), the input image from the camera 104 and the input voice from the microphone 106 are notified via the in-home wireless communication unit 110 together with the detection information. Transmit to terminal 2. 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, when there is no occupant (the presence / absence information of all users is “going out”), it is necessary to deal directly with the monitoring center. Regardless, the current input image and input voice are transmitted to the monitoring center in real time via the public 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 monitoring process in the semi-monitoring area 5 will be described.
The monitoring control unit 118 ignores the detection signal input from the sensor 100 while the non-monitoring state is set. In other words, do not monitor public road passers. While the monitoring state is set, a human body that has entered the regular monitoring area 5 is detected based on the detection signal input from the sensor 100, the movement of the human body is tracked, and the suspicious person is monitored. When detecting the human body, the monitoring control unit 118 drives the tag reader 102 to read the wireless tag in the semi-monitoring area 5 and refers to the user management information in the storage unit 116 to determine whether or not the detected human body is a user. Is determined. If the detected human body is not a user, the detected movement of the human body is tracked in order to discriminate between a mere passerby and a suspicious person. When the monitoring control unit 118 detects that the human body being tracked stays in the semi-monitoring area for a predetermined time, the monitoring control unit 118 recognizes the person as a suspicious person (or a suspicious person candidate) and stores an input image from the camera 104. This is recorded as an accumulated image in the unit 116. At the same time, the input image from the camera 104 and the input sound from the microphone 106 are transmitted in real time to the monitoring center via the public wireless communication unit 112. Further, the input image and the input voice are transmitted to the notification terminal 2 together with the detection information via the home wireless communication unit 110, and the other users in the home are notified of the situation.

Next, the flow of processing executed by the monitoring control unit 118 when an intruder appears in the monitoring area 3 will be described with reference to FIGS.
4 to 6 are flowcharts showing the monitoring process when detecting a human body in the monitoring area. When the monitoring control unit 118 detects a person (human body) in the monitoring area based on the detection signal input from the sensor 100, the monitoring control unit 118 executes the following monitoring process.

  When the detection signal is input from the sensor 100, the monitoring control unit 118 determines whether the detected position is the regular monitoring area 3 or the semi-monitoring area 5 based on the area map information in the storage unit 116 (step 202). ). In the case of human body detection in the regular monitoring area 3 (No in step 202), tracking of the person who appears in the regular monitoring area 3 is started (step 204), and it is determined whether the tag reader 102 has detected a wireless tag. (Step 206). 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 118 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 206), 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 appearance point of the detected person. It is determined whether the entry is to the area 3 or the entry to the monitoring area 3 from the building (step 208). 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 210). 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 118 refers to the user management information to check whether there is a resident in the building (step 212). 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 214). The monitoring center performs real-time processing of images and sounds sent from the site, and monitors whether the detected person moves suspiciously. The monitoring control unit 118 outputs a warning message from the speaker 108 when the person stays in the site for a predetermined time or more (step 216). Also, audio data received from the monitoring center is output from the speaker 108.

  When there is a person at home (Yes in Step 212), the captured image and acquired voice data are transmitted to the notification terminal 2 in the house, and are 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 118 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 214 to 216). 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 the monitoring control unit 118 determines that the position detected based on the area map information in the storage unit 116 is the semi-monitoring area 5 when the detection signal is input from the sensor 100 (Yes in Step 202), The process proceeds to the semi-monitoring area monitoring process (to C).
First, the monitoring control unit 118 refers to the user management information to check whether there is a resident in the building (step 402). When there is no resident, that is, when the presence / absence information of all the users is “going out”, since the semi-monitoring area 5 is in the non-monitoring state, the monitoring process is terminated. If there is a person at home, the action state of the user at home is confirmed, and it is determined whether there is a user in a specific action state corresponding to the semi-monitoring area 5 where the person is detected (step) 404). If there is no resident in the corresponding specific action state, the semi-monitoring area 5 is in the non-monitoring state, and thus the monitoring process is terminated.

  On the other hand, if there is a person in the corresponding specific action state, the semi-monitoring area 5 is in the supervised state, so that tracking of the person who appears in the semi-monitoring area 5 is started (step 406) and the tag reader It is determined whether 102 detects a wireless tag (step 408). If there is a wireless tag in the monitoring area 3, it is recognized as a valid user and the monitoring process is terminated.

  When the wireless tag cannot be detected in the monitoring area 3, the detected person is recognized as a person other than the user, and a monitoring timer for suspicious person determination is started (step 410). Then, it is monitored whether the detected person continues to stay in the semi-monitoring area 5 or has left until the monitoring timer finishes counting the predetermined time (steps 412 to 414).

  If the person who is being tracked leaves before the monitoring timer expires and disappears from the semi-monitoring area 5, it is recognized that the person is not a suspicious person but a general passerby, and the process is terminated. On the other hand, when the time is up without disappearing from the semi-monitoring area 5, there is a possibility that the person is a suspicious person who stays in the semi-monitoring area 5. Therefore, the monitoring control unit 118 starts recording of the captured image by the camera 104, transmits the captured image and the acquired voice data to the in-home notification terminal 2, and causes the notification terminal 2 to display and output (step 416). At the same time, the captured image and acquired voice data are transmitted to the monitoring center (step 418). The monitoring center performs real-time processing of images and sounds sent from the site, monitors whether the detected person looks suspiciously such as peeping, and receives warning messages from the speaker 108 or received from the monitoring center as necessary. Audio data is output from the speaker 108 (step 420).

  As described above, the security system according to the present embodiment automatically enters and exits a user's building without requiring any special operation, and enters the regular monitoring area where the outer periphery of the building is constantly monitored. When an action is detected, different alarm processing is executed according to the presence / absence information of the user. Even if the outer periphery of the building includes an area where people other than users pass, such as public roads, this area is defined as a semi-monitoring area, and only when the user is in a specific behavioral state (for example, bathing) The suspicious person is monitored with the semi-monitoring area outside the monitoring state. As a result, it is possible to eliminate the user's anxiety and ensure safety while suppressing the decrease in convenience caused by monitoring public roads.

  In the above-described embodiment, the example is described in which the bathing state is a specific action state and the public road facing the bathroom is a semi-monitoring area. However, the specific action state and the semi-monitoring area are not limited thereto. For example, a public road facing a room in which a safe is placed can be set as a semi-monitoring area, and a specific action state can be handled while a user is in the room or while the safe is opened by a safe sensor or the like.

  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 person at home, a notification operation is performed by the user to notify the monitoring center, but a notification is made when the cancel operation is not performed for a predetermined time. It can also be configured. 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. For example, 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. Further, the notification terminal receives a signal from the internal reader 4 and manages user management information (presence / absence information, action state).

  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.

  In the security system of the above embodiment, the user behavior monitoring in the home area is performed by the internal reader installed corresponding to each room. Means may be used. For example, three or more internal readers with the entire home area as the detection area are installed in different locations, and the location of the home area is measured by three-point positioning based on the reception intensity of the response wave from the wireless tag detected almost simultaneously. It can also be set as the structure which identifies the partial area which exists now from the positional relationship with information, and a movement and a stop from the change of a measurement position. Moreover, it can also be set as the structure which pinpoints the position in a house using the UWB (UltraWideBand) sensor which makes the detection area the whole home area.
