Description

  The present invention relates to a security system that monitors a mobile body that has entered a monitoring area.

Conventionally, intruders such as intruders who have entered a preset monitoring area are detected using any of various sensors, and when an intruder is detected, an alarm is issued or an intrusion abnormality is monitored. Security systems that report to the center are used. Such a security system reports an abnormality when a sensor detects a user even when a user having a right to enter the monitoring area enters the monitoring area. Therefore, every time the user enters the monitoring area, it is necessary to operate the security system to cancel the intrusion monitoring. Such an operation is complicated for the user.
Therefore, in order to enhance the convenience of the user, even if the user has a wireless tag and the sensor detects an intruder in the monitoring area, the intruder can detect the wireless tag if the intruder is detected. A security system has been proposed that recognizes that it is an intrusion abnormality (see, for example, Patent Document 1).

JP 2005-182340 A

In general, a security system monitors a space inside a building, such as a house, or a boundary as a monitoring area, but before a suspicious person enters the building, in order to quickly detect and report a suspicious person, For example, a detached house garden may be set as a monitoring area.
However, there is a possibility that various persons who are neither users nor suspicious people may enter the garden of the house, such as a delivery person who delivers a delivery product, a meter meter of a facility such as water and gas, and a general visitor. Therefore, when the above security system is operated with the garden of the house as the monitoring area, the person who does not have the wireless tag that enters the garden is uniformly judged as an intruder, and enters the monitoring area of the delivery person etc. There was a risk that misinformation would occur frequently.
On the other hand, if an area where such a person who is neither a user nor a suspicious person may enter is excluded from the monitoring area, the security system described above cannot reliably detect the intrusion of the suspicious person into the premises. , Security will be reduced.

  Then, an object of this invention is to provide the security system which can identify correctly whether the moving body which entered the monitoring area set in the building periphery is a suspicious object.

  As one form of this invention, the security system which detects the suspicious object which invaded the monitoring area around a building and issues a warning is provided. This security system includes detection means for detecting the position of a moving body in a monitoring area, storage means for storing each range of a plurality of partial areas obtained by dividing the monitoring area, and that the moving body has moved between the partial areas. Monitoring processing means for determining whether or not the moving body is a suspicious object according to a transition type composed of a combination of the movement source partial area and the movement destination partial area.

  The security system further includes an identification unit that acquires the identification information of the mobile object, and the monitoring processing unit specifies the authority of the mobile object from the acquired identification information, and determines the authority according to the specified authority and the transition type. It is preferable to determine whether the moving body is a suspicious object.

The partial area includes a first partial area including the vicinity of the entrance to the monitoring area and a second partial area adjacent to the first partial area, and the monitoring processing means is configured such that the moving body enters the monitoring area. When there is no authority, when the moving body moves from the outside area of the monitoring area to the first partial area, and when the moving body moves from the first partial area to the second partial area, the moving body is determined as a suspicious object. On the other hand, when the moving body moves from the outside area of the monitoring area to the second partial area, it is preferable to determine the moving body as a suspicious object.
In addition, even if the moving body does not have the authority to enter the monitoring area, the monitoring processing means may remove the suspicious object when the moving body moves from the building surrounded by the monitoring area to the monitoring area. In order to prevent false alarms, it is preferable not to make a determination.

  Furthermore, the monitoring processing means determines whether the moving object has entered the monitoring area from the outside area or the building surrounded by the monitoring area, depending on the appearance position of the moving object that has entered the monitoring area. It is preferable.

  Moreover, it is preferable that the monitoring processing means detects whether or not the moving body is staying in any partial area in the monitoring area. When the monitoring processing unit detects that the moving body is staying, it is preferable to determine whether or not the moving body is a suspicious object according to the authority assigned to the moving body.

  As another embodiment of the present invention, there is provided a security system that detects a moving body that has entered a monitoring area around a building and executes various warning processes. This security system includes detection means for detecting the position of a moving body in a monitoring area, map information storage means for storing each range of a plurality of partial areas obtained by dividing the monitoring area, and movement between the partial areas. Alarm information storage means for storing alarm processing to be executed for each transition type consisting of a combination of a movement source partial area and a movement destination partial area, and movement when it is detected that the mobile body has moved between the partial areas Monitoring processing means for executing alarm processing stored in the alarm information storage means in accordance with the transition type.

  The security system further includes an identification unit that acquires the identification information of the mobile object, and the alarm information storage unit stores an alarm process to be executed for each transition type for each authority specified from the acquired identification information. Then, it is preferable that the monitoring processing unit specifies the authority of the mobile body from the acquired identification information, and executes the alarm process stored in the alarm information storage unit according to the specified authority and the transition type.

  The security system according to the present invention has an effect that it is possible to accurately identify whether or not the moving body that has entered the monitoring area set on the outer periphery of the building is a suspicious object. In particular, this security system can accurately identify a non-malicious person who has entered temporarily and a suspicious person, depending on how the moving body enters the monitoring area or how it moves within the monitoring area.

Hereinafter, a security system according to one embodiment of the present invention, which uses a detached house site as a monitoring area, detects a suspicious object that has entered the site, and issues an alarm, will be described with reference to the drawings. This security system divides the monitoring area into a plurality of partial areas, and sets the authority to enter each partial area. The security system then determines whether the moving body is a suspicious object based on the authority assigned to the moving body that has entered the monitoring area and the movement history between the partial areas of the moving body or the approach path to the monitoring area. It is determined whether or not.
In the present embodiment, a person who has entered the monitoring area is an example of a moving body, and the security system determines whether the person who has entered the monitoring area is a suspicious object, that is, whether or not it is a suspicious person.

FIG. 1 is a diagram showing an overall system configuration of a security system 1 according to one embodiment. As shown in FIG. 1, the security system 1 is installed around a house, and has at least one sensor terminal 2 that monitors at least a part of a site that is a monitoring area, and each sensor terminal 2 through a communication line. And a monitoring terminal 3 that is connected and installed in the house.
Further, the security system 1 includes a permission tag 4 and a restriction tag 5 possessed by a specific person such as a user. Each of the permission tag 4 and the restriction tag 5 can be a wireless tag, for example, and can communicate with the sensor terminal 2 wirelessly. When the permission tag 4 and the restriction tag 5 receive the question signal from the sensor terminal 2, the permission tag 4 and the restriction tag 5 return the identification code of the tag stored in the built-in memory.

  The sensor terminal 2 detects a person who has entered the monitoring area, detects the permission tag 4 or the restriction tag 5, and notifies the monitoring terminal 3 of the detection result. Based on the detection result from the sensor terminal 2, the monitoring terminal 3 determines whether the person who entered the monitoring area is a suspicious person. If the monitoring terminal 3 determines that the person who entered the monitoring area is a suspicious person, the monitoring terminal 3 issues an abnormality report indicating that the suspicious person has been detected to the monitoring center apparatus 6 connected via the public communication line. .

The monitoring terminal 3 uses authority information specified by the tag detected by the sensor terminal 2 when determining the suspicious person.
The authority information is information indicating the degree to which entry into the monitoring area is permitted, and three levels of authority are set in this embodiment.
The authority with the most authority is the authority set in the permission tag 4 and represents that unlimited entry into the monitoring area is permitted. Therefore, the permission tag 4 is possessed by a user such as a resident of a building where the security system 1 is installed. In the present embodiment, a person possessing the permission tag 4 is called a permitted person.
Next, the authority having authority is the authority set in the restriction tag 5 and represents that entry into a specific area in the monitoring area is permitted. Therefore, the restriction tag 5 is possessed by a person, such as a gardener, who is permitted to enter a specific area in the monitoring area by the user. In the present embodiment, a person possessing the restriction tag 5 is called a restriction permitter.
A person who possesses neither the permission tag 4 nor the restriction tag 5 is called a non-permitted person. Non-permitted persons are only allowed to temporarily enter certain areas within the surveillance area.
Note that the types of authority are not limited to three. For example, only two types of authority, an authorized person and an unauthorized person, may be set.

  FIG. 2 is a diagram illustrating an example of a monitoring area installed on the outer periphery of a building where the security system 1 is installed. In this example, the monitoring area 100 is set to the entire site on the outer periphery of the building 110. The monitoring area 100 is divided into a plurality of partial areas. In this example, the monitoring area 100 is divided into three types of partial areas: a service area 101, a restricted area 102, and a prohibited area 103. And the sensor terminal 2 is each installed in each surface of the outer periphery of the building 110 so that the monitoring area 100 whole can be monitored. A monitoring terminal 3 is installed inside the building 110.

The service area 101 is set, for example, in an area including a passage from the service entrance 120 to the site (ie, the monitoring area) to the entrance 130 of the building 110. Not only authorized persons but also restricted authorized persons can enter the service area 101. That is, even if a restricted permitter is detected in the service area 101, it is not determined as a suspicious person by itself.
In addition, although the non-permitted person can temporarily enter the service area 101, the non-permitted person cannot stay in the service area 101 beyond a predetermined period. That is, the security system 1 does not determine that the non-permitted person is a suspicious person just by entering the service area 101, but if the non-permitted person stays in the service area 101 for a predetermined period of time, The unauthorized person is determined as a suspicious person. This is because there is a possibility that a person who does not have any tag, such as a meter reader or a delivery person, may enter the service area 101 due to legitimate circumstances. This is to prevent the occurrence of the above. However, even in the service area 101, a non-permitted person who stays for a long time may be a person who attempts to illegally enter the building 110, for example, picking. Such a staying person is determined to be a suspicious person.

The restricted area 102 includes, for example, an area where a non-permitted person may temporarily enter other than a service area such as an area where a meter-reading meter is installed, and an area where a restricted authorized person may work. Set to Not only authorized persons but also restricted persons can enter the restricted area 102.
In addition, even a non-permitted person can enter the restricted area 102 temporarily, but the non-permitted person cannot stay in the restricted area 102 beyond a predetermined period. That is, the security system 1 does not determine that the non-permitted person is a suspicious person just by entering the restricted area 102, but if the non-permitted person stays in the restricted area 102 for a predetermined period of time, Similar to the service area 101, the non-permitted person is determined as a suspicious person. This is because there is a possibility that a person who does not have any tag such as a meter reader may enter the restricted area 102 due to legitimate circumstances, and to prevent misreporting by determining such a person as a suspicious person. It is.

  The prohibited area 103 is an area where entry of persons other than the authorized person is prohibited. Therefore, when a restricted permitter or non-permitted person enters the prohibited area 103, the security system 1 determines that the restricted permitter or non-permitted person is a suspicious person in principle.

Further, the non-monitoring area on the outer periphery of the monitoring area 100 is an off-site area and is distinguished from the monitoring area 100. Furthermore, the area corresponding to the building 110 is an indoor area, and is distinguished from the monitoring area 100 and the off-site area. As a general rule, this indoor area is an area where only authorized persons can enter. However, after the operation permitting entry by the monitoring terminal 3, for example, the monitoring canceling operation or the unlocking operation of the entrance, a restricted permitter or a non-permitted person is allowed to enter the indoor area.
In the example shown in FIG. 2, the monitoring area is set to the entire outer periphery of the building, but the monitoring area may be set to only a partial region of the outer periphery of the building in the site.

  FIG. 3 is a schematic configuration diagram of the sensor terminal 2. The sensor terminal 2 includes a sensor 21, tag reader 22, camera 23, microphone 24, storage unit 25, power supply unit 26, home communication unit 27, speaker 28, and control unit 29.

The sensor 21 is a human body detection sensor that detects a person who has entered the monitoring area. For example, a laser distance measuring sensor can be used as the sensor 21. The laser distance measuring sensor scans the laser in a horizontal direction in a predetermined angle step (eg, 0.1 ° unit) over a preset scanning range (eg, 180 °), detects the reflected light of the laser, for example, The distance to the object reflecting the laser is measured by the Time-of-Flight method. The sensor 21 scans the entire scanning range at a constant cycle. The sensor 21 measures the distance to the point where the laser is reflected at each angle in the scanning range, and notifies the control unit 29 of distance measurement data that associates the measured distance with the angle.
The sensor 21 may be configured to scan the laser two-dimensionally in the horizontal and vertical directions and obtain three-dimensional data including the scanning direction and the measurement distance. As for the distance measuring method, various known methods may be employed. For example, a phase difference method, a triangulation method, or the like can be used.

The tag reader 22 is an example of a human body identification sensor that identifies a person who has entered the monitoring area. For this purpose, the tag reader 22 communicates with the permission tag 4 and the restriction tag 5 located within a predetermined range. The predetermined range is set such that, for example, a tag possessed by a person in an arbitrary location within the monitoring area can communicate with the tag reader 22 of at least one of the sensor terminals 2. Preferably, the predetermined range is substantially the same as the monitoring area included in the scanning range of the sensor 21 of the same sensor terminal 2.
The tag reader 22 radiates an inquiry signal at a constant cycle, for example. When the tag reader 22 receives the response signal from the permission tag 4 or the restriction tag 5 in response to the question signal, the tag reader 22 analyzes the response signal and extracts the tag identification code included in the response signal. Then, the tag reader 22 notifies the control unit 29 of the extracted identification code.

  The camera 23 captures a predetermined area in the monitoring area at a predetermined cycle, and generates an image of the predetermined area. The camera 23 passes the generated image to the control unit 29. The predetermined area is set such that, for example, an arbitrary place in the monitoring area is captured by the camera 23 of at least one of the sensor terminals 2. Preferably, the predetermined area is set so that the monitoring area included in the scanning range of the sensor 21 of the same sensor terminal 2 can be photographed. For example, in the example of FIG. 2, the camera 23 of each sensor terminal 2 has a field angle of about 180 °.

  The microphone 24 collects sound around the sensor terminal 2, converts the collected sound into an electric signal, digitizes it, and passes it to the control unit 29.

  The storage unit 25 includes, for example, a nonvolatile semiconductor memory and stores various information and programs used in the sensor terminal 2. For example, the storage unit 25 stores an identification code of the sensor terminal 2 and the like. Then, the storage unit 25 outputs the stored information and program to the control unit 29. Alternatively, the storage unit 25 stores information received from the control unit 29.

The power supply unit 26 supplies power to each unit of the sensor terminal 2. For this purpose, the power supply unit 26 includes, for example, a transformer, a rectifier, and the like, acquires AC power from commercial power wiring in the building, converts the AC power into DC power of a predetermined voltage, and the DC power. Is supplied to each part.
The power supply unit 26 may be a storage battery such as an alkaline manganese battery or a lithium ion battery.

The in-home communication unit 27 connects the sensor terminal 2 and the monitoring terminal 3 so that they can communicate with each other. Therefore, the in-home communication unit 27 includes an interface circuit for wireless communication when the sensor terminal 2 and the monitoring terminal 3 are connected in accordance with a predetermined wireless communication method such as specific low power wireless communication. Alternatively, the in-home communication unit 27 may include an interface circuit that terminates a communication line that connects the sensor terminal 2 and the monitoring terminal 3.
The in-home communication unit 27 transmits the distance measurement data output from the control unit 29, the tag identification code, and the like to the monitoring terminal 3. The in-home communication unit 27 passes the control signal, image request signal, audio request signal, audio data, and the like received from the monitoring terminal 3 to the control unit 29.

  The speaker 28 outputs the audio data received from the control unit 29 as an audio signal.

The control unit 29 has at least one processor and its peripheral circuits. The control unit 29 controls each unit of the sensor terminal 2.
The control unit 29 controls communication with the monitoring terminal 3. Specifically, the control unit 29 transmits the distance measurement data for one cycle received from the sensor 21 to the monitoring terminal 3 through the in-home communication unit 27 together with the identification code of the sensor terminal 2. Further, the control unit 29 transmits the tag identification code detected by the tag reader 22 to the monitoring terminal 3 through the home communication unit 27 together with the identification code of the sensor terminal 2.
Further, when receiving an image request signal from the monitoring terminal 3, the control unit 29 transmits an image captured by the camera 23 to the monitoring terminal 3 via the home communication unit 27. In addition, when receiving the voice request signal from the monitoring terminal 3, the control unit 29 transmits the voice signal collected by the microphone 24 to the monitoring terminal 3 via the home communication unit 27.
In addition, when receiving voice data such as a warning message from the monitoring terminal 3, the control unit 29 transmits the voice data to the speaker 28.

  FIG. 4 is a schematic configuration diagram of the monitoring terminal 3. The monitoring terminal 3 includes a speaker 31, a monitor 32, an operation unit 33, a power source 34, a home communication unit 35, a center communication unit 36, a storage unit 37, and a monitoring processing unit 38.

  When the monitoring processing unit 38 determines that an event such as detecting a suspicious person in the monitoring area or when the user returns home, the speaker 31 outputs a sound signal corresponding to the event. 38 is received and notified as voice. In addition, the speaker 31 may selectively receive an audio signal collected by a microphone of any one of the sensor terminals 2 from the monitoring processing unit 38 in accordance with an operation via the operation unit 33 and notify it as a sound.

  The monitor 32 displays various guide information related to the operation of the security system 1, the detection result of the suspicious person, and the like. In addition, the monitor 32 may selectively receive an image captured by the camera of any one of the sensor terminals 2 from the monitoring processing unit 38 and display it in accordance with an operation via the operation unit 33.

The operation unit 33 has, for example, a plurality of operation buttons. When the user presses any one of the operation buttons, a predetermined operation signal assigned to the operation button is output to the monitoring processing unit 38. And the user can lock / unlock the electric lock (not shown) provided in the entrance / exit of the building by operating the operation part 33. In addition, the user can operate the operation unit 33 to output the sound collected by the sensor terminal 2 to the speaker 31 or display the image captured by the center terminal 2 on the monitor 32. Furthermore, when the monitoring processing unit 38 determines that there is a suspicious person in the monitoring area, the user can notify the monitoring center that the suspicious person has been detected by operating the operation unit 33. .
The monitor 32 and the operation unit 33 may be integrally configured as a touch panel display.

  The power supply 34 supplies power to each part of the monitoring terminal 3. For that purpose, the power supply 34 has, for example, a transformer, a rectifier, and the like, and acquires AC power from commercial power wiring in the building, converts the AC power into DC power of a predetermined voltage, and converts the DC power into Supply to each part.

The in-home communication unit 35 connects the monitoring terminal 3 and the sensor terminal 2 so that they can communicate with each other. Therefore, the in-home communication unit 35 includes an interface circuit for wireless communication when the monitoring terminal 3 and the sensor terminal 2 are connected according to a predetermined wireless communication method such as specific low power wireless communication. Alternatively, the home communication unit 35 may include an interface circuit that terminates a communication line that connects the monitoring terminal 3 and the sensor terminal 2.
The in-home communication unit 35 transmits the control signal, the image request signal, the audio request signal, the audio data, and the like output from the monitoring processing unit 38 to the sensor terminal 2. The in-home communication unit 35 receives distance measurement data, a tag identification code, an image signal, an audio signal, and the like from the sensor terminal 2 and passes them to the monitoring processing unit 38.

  The center communication unit 36 has an interface circuit for connecting the monitoring terminal 3 to a public communication line. For example, when the center communication unit 36 notifies the monitoring center device 6 that a suspicious person has been detected, the center communication unit 36 performs a connection process between the monitoring terminal 3 and the monitoring center device 6 according to the control of the monitoring processing unit 38. Then, the center communication unit 36 establishes the connection between the monitoring terminal 3 and the monitoring center device 6 and then receives the identification code of the security system 1 or the building where the security system 1 is installed received from the monitoring processing unit 38, and the suspicious An abnormality notification signal indicating that the person has been detected is transmitted to the monitoring center device 6 via the public communication line. The center communication unit 36 may also transmit the audio signal collected by the sensor terminal 2 or the image captured by the sensor terminal 2 to the monitoring center device 6 via the public communication line. The center communication unit 36 performs a process of releasing the connection between the monitoring terminal 3 and the monitoring center device 6 when the notification of various information as described above is finished.

The storage unit 37 includes, for example, a nonvolatile semiconductor memory, and stores various information and programs used in the monitoring terminal 3. The storage unit 37 stores map information indicating the range of the entire monitoring area, the range of each partial area and indoor area in the monitoring area, and map information indicating the position of an object such as a tree or a fence existing in the monitoring area in advance. Functions as a means.
For example, the storage unit 37 holds the information of the monitoring area 100 shown in FIG. 2 as map information represented in a two-dimensional coordinate system with the position of the lower left corner of the monitoring area 100 as the origin. In the monitoring area 100, the boundary with the area outside the site is defined by the coordinates of the outer side, and the boundary with the building is defined by the coordinates of the inner side. And the area | region except the area | region enclosed by the inner side used as the boundary with a building among the area | regions enclosed by the outer side is set as the range of the monitoring area 100. FIG.
In addition, information representing the range of each partial area in the monitoring area, such as a service area, is defined as an area surrounded by a boundary line between the partial areas.
Further, the map information may include the positions of entrances and exits such as the entrance to the monitoring area, that is, the entrance to the monitoring area, the entrance of the building, the entrance, and the window.

  The storage unit 37 is connected to the monitoring terminal 3 as information necessary for the monitoring processing unit 38 to calculate the position of the object detected in the monitoring area from the distance measurement data obtained by the sensor 21 of each sensor terminal 2. The identification code of each sensor terminal 2, the coordinates indicating the installation position of each sensor terminal 2 in the monitoring area, the reference direction of the scanning range of the sensor 21 of each sensor terminal 2 (for example, the center direction of the scanning range), the monitoring area Reference measurement data by the sensor 21 of each sensor terminal 2 measured in the absence of a person is stored.

  Further, the storage unit 37 functions as an alarm information storage unit, and stores an event table representing an event such as an alarm process that occurs in response to movement or stagnation of a person detected in the monitoring area for each authority. To do. Details of the event table will be described later.

In addition, the storage unit 37 stores an authority table that represents the relationship between the identification codes of the permission tag 4 and the restriction tag 5 and the authority information set in these tags.
Furthermore, when there is a person detected in the monitoring area, the storage unit 37 stores tracking data set for the person. Details of the tracking data will be described later.
Furthermore, the storage unit 37 may store images, audio signals, and the like received from each sensor terminal 2. The storage unit 37 then outputs the stored information and program to the monitoring processing unit 38. Alternatively, the storage unit 37 stores information received from the monitoring processing unit 38.

The monitoring processor 38 has at least one processor and its peripheral circuits. The monitoring processing unit 38 has a timer circuit. The monitoring processing unit 38 controls each unit of the monitoring terminal 3. The monitoring processing unit 38 detects a person in the monitoring area based on the distance measurement data received from each sensor terminal 2 and the identification code of the wireless tag, and determines whether the person in the monitoring area is a suspicious person. To determine.
The monitoring processing unit 38 executes various warning processes based on the movement history and authority of the person in the monitoring area.

  The monitoring processing unit 38 compares the distance measurement data received from each sensor terminal 2 with the reference measurement data stored in the storage unit 37, extracts the direction (scanning angle) in which the distance change is greater than or equal to a predetermined value, A distance change direction group having a measurement distance difference within a certain value and having a continuity (for example, a general human size) of a predetermined value or more is determined as a person who has entered the monitoring area. Then, the monitoring processing unit 38, the map information stored in the storage unit 37, the installation position coordinates of the sensor terminal 2, the reference direction of the scanning range of the sensor 21, and the representative distance measurement data (for example, the detected person) The position of the person in the monitoring area (that is, the position coordinates on the map information) is calculated from the scanning direction at the center of the distance change direction group and the measurement distance. Since the calculation of such a position can be performed by a simple coordinate system conversion operation, its details are omitted.

FIG. 5 is a flowchart showing the operation of the person tracking process executed by the monitoring processor 38. When the monitoring processing unit 38 detects a person in the monitoring area based on the distance measurement data, the monitoring processing unit 38 performs person tracking processing for each detected person according to the flowchart shown in FIG. The person tracking process is executed every time a person is detected in distance measurement data that is repeatedly input every predetermined cycle (for example, every time the sensor 21 of the sensor terminal 2 performs one scan). Here, one person tracking process is called one scan for convenience.
First, the monitoring processor 38 determines whether or not the detected person is a person being tracked (step S101). For example, any of various known tracking processes can be used to determine whether or not the person is being tracked. For example, if the distance between the position of the person of interest detected in the current scan and the position of any person detected before one scan is less than or equal to a predetermined distance estimated from the person's movable speed, monitoring is performed. The processing unit 38 determines that the person of interest is the same as the person detected before one scan. Further, the monitoring processing unit 38 confirms that the identification code of the tag possessed by the person of interest in the current scan is the same as the identification code of the tag possessed by the person detected before one scan, It may be added to the condition for determining that the person is the same as the person detected in (1).

If a person who is determined to be the same person as the person of interest in the current scan is not detected before one scan, the monitoring processing unit 38 determines that the person of interest is not the person being tracked (step S101—No). ). Then, the monitoring processing unit 38 assigns a person identification code different from the person being tracked to the person of interest (step S102).
Further, based on the tag identification information received from the sensor terminal 2, the monitoring processing unit 38 performs authority setting processing for the person of interest (step S103). Through this authority setting process, the monitoring processor 38 sets the authority of an authorized person, a restricted authorized person, or a non-permitted person for the person of interest.

FIG. 6 is a flowchart showing the operation of authority setting processing corresponding to step S103 of FIG.
The monitoring processing unit 38 determines whether or not the identification code extracted from the response signal from the permission tag 4 or the restriction tag 5 has been received from any sensor terminal 2 (step S201). When the identification code of any tag has not been received, the monitoring processor 38 sets the person identification code assigned to the person of interest as a non-permitted person (step S202). On the other hand, when the identification code of any tag is received, the monitoring processing unit 38 refers to the tracking code of another person being tracked, and the detected tag identification code is included in any tracking code. It is determined whether or not it matches the identification code of the tag stored in (step S203). If the received tag identification code matches the tag identification code stored in one of the tracking codes, the wireless tag corresponding to the received tag identification code is owned by another person being tracked. Presumed to be. Therefore, also in this case, the monitoring processing unit 38 sets the person identification code assigned to the person of interest as a non-permitted person (step S202). On the other hand, if the received tag identification code does not match the tag identification code stored in any of the tracking codes, the monitoring processing unit 38 refers to the authority table and determines the authority corresponding to the received tag identification code. The information is specified, and the specified authority information is set as the authority of the person identification code assigned to the person of interest (step S204). That is, if the received identification code of the tag is the identification code of the permission tag 4, the monitoring processing unit 38 sets the person of interest as the authorized person. If the received identification code of the tag is the identification code of the restriction tag 5, the monitoring processing unit 38 sets the person of interest as the restriction authorized person.
After step S202 or S204, the monitoring processing unit 38 ends the authority setting process.

Referring to FIG. 5 again, after the authority setting process is executed, the monitoring processing unit 38 sets tracking data for the person of interest (step S104). The tracking data includes the following information:
・ Personal identification code ・ Tag identification code ・ Authority information ・ Latest position coordinates of the person of interest ・ Current location area information ・ Previous location area information ・ Area transition time Among these, the authorization information is the above-mentioned authorized person or restricted authorized person Or it is the information showing either non-permitted person. Also, the current location area information is an identification code of a partial area where the person of interest is present in the current scan. The previous location area information is an identification code of the partial area where the person of interest is located before entering the partial area where the person is currently located. In addition, since it is possible to move from the off-site area or the indoor area in the monitoring area, an identification code representing the off-site area or an identification code representing the indoor area may be stored as the previous location area information. is there. Further, the area transition time is a time when it is confirmed that the area has moved from the previous location area to the current location area.

For example, the monitoring processing unit 38 compares the latest position coordinates of the person of interest with the range information of each partial area included in the map information, and determines which partial area the person of interest is in. For example, if the latest position coordinates of the person of interest are included in coordinates defining a predetermined partial area, the monitoring processing unit 38 determines that the person of interest is located in the predetermined partial area. The monitoring processing unit 38 then determines the distance from the latest position coordinates of the person of interest to the boundary between the monitoring area and the off-site area (hereinafter referred to as the approach distance for convenience), and the boundary between the monitoring area and the indoor area (or the indoor area). And the distance to the nearest entrance / exit that can enter (hereinafter referred to as the exit distance for convenience). If the approach distance is smaller than the exit distance, the monitoring processing unit 38 sets the identification code of the off-site area in the previous location area information. On the other hand, if the exit distance is equal to or less than the approach distance, the monitoring processing unit 38 sets the indoor area identification code in the previous location area information. Furthermore, the monitoring processor 38 sets the current scanning time as the area transition time.
The monitoring processing unit 38 stores the created tracking data in the storage unit 37.

On the other hand, if a person determined to be the same person as the person of interest in the current scan is detected before one scan, the monitoring processing unit 38 determines that the person of interest is the person being tracked (step S101). -Yes). Then, the monitoring processing unit 38 reads tracking data created for the person determined to be the same person as the person of interest in the current scanning from the storage unit 37, and updates the tracking data (step S105).
Specifically, the monitoring processing unit 38 rewrites the latest position coordinates included in the tracking data to the position coordinates of the person of interest detected in the current scan. Further, the monitoring processing unit 38 compares the latest position coordinates of the person of interest with the range information of each partial area, and determines which partial area the person of interest is in. If the partial area where the person of interest is located coincides with the current location area indicated in the tracking data, the monitoring processing unit 38 does not rewrite the current location area information, the previous location area information, and the area transition time.
On the other hand, if the partial area where the person of interest is located is different from the current location area indicated in the tracking data, the monitoring processing unit 38 sets the identification code of the previous location area information to the part indicated in the current location area information. Rewrite the area ID code. Then, the monitoring processing unit 38 rewrites the current location area information with the identification code of the partial area where the target person is located in the current scan. Furthermore, the monitoring processing unit 38 rewrites the area transition time with the current scanning time.
The monitoring processing unit 38 stores the updated tracking data in the storage unit 37.

After step S104 or step S105, the monitoring processor 38 determines whether or not the person of interest has moved between the partial areas (step S106). When the monitoring processing unit 38 sets tracking data for a person who newly appears in the monitoring area in step S104, or when the current location area information of the person being tracked is updated in step S105, the person of interest is It is determined that the movement has occurred between the partial areas.
When the person of interest has not moved between the partial areas (step S106-No), the monitoring processing unit 38 calculates the residence time that is the absolute value of the difference between the area transition time in the tracking data of the person of interest and the current scanning time. calculate. Then, the monitoring processor 38 determines whether or not the residence time is equal to or longer than a predetermined time (step S107). This predetermined time is a time estimated that a person may perform some suspicious behavior (for example, picking, peeping, breaking glass), etc. in a partial area. Or longer than the time required for temporary work such as delivery and meter reading. For example, the predetermined time is set to 30 seconds. The predetermined time may be a different value depending on the type of the partial area. For example, the predetermined time may be set the longest for the service area and the shortest for the prohibited area. Furthermore, the predetermined time may be a different value depending on the type of authority of the person of interest. For example, the predetermined time for the non-permitted person may be set shorter than the predetermined time for the restricted permitter. It should be noted that the predetermined time is not limited for the permitter so that the stay determination is not executed.

If the staying time is less than the predetermined time (step S107-No), the monitoring processing unit 38 ends the person tracking process because no event occurs.
On the other hand, when the person of interest moves between partial areas (step S106-Yes), or when the staying time is a predetermined time or more (step S107-Yes), the monitoring processing unit 38 includes the authority information included in the tracking data. , The authority set for the person of interest is specified (step S108). Alternatively, the monitoring processing unit 38 refers to the authority table and identifies the authority corresponding to the tag identification code included in the tracking data as the authority set for the person of interest. Then, the monitoring processing unit 38 reads an event table corresponding to the specified authority from the storage unit 37. The monitoring processing unit 38 refers to the read event table, and an event occurs depending on the combination of the current location area and the previous location area when moving between partial areas, if it is staying. It is determined whether or not to perform (step S109). When the event does not occur (step S109—No), the monitoring processing unit 38 ends the person tracking process.
On the other hand, when some event occurs (step S109—Yes), the monitoring processing unit 38 executes a process according to the event defined in the event table (step S110). Thereafter, the monitoring processing unit 38 ends the person tracking process.

In addition, when there is tracking data that has not been updated for a certain period or longer, the monitoring processing unit 38 executes an unupdated tracking data update process described below. Such unupdated tracking data occurs, for example, when the person of interest moves from the monitoring area to the indoor area or the off-site area and cannot be detected by the sensor terminal 2. For example, the certain period can be a period corresponding to one scan or a plurality of scans.
FIG. 7 is a flowchart showing the operation of the unupdated tracking data update process executed by the monitoring processor 38.
The monitoring processing unit 38 specifies the destination area from the position of the person of interest corresponding to the non-updated tracking data at the last update indicated in the non-updated tracking data (step S301). For example, if the approach distance required for the position of the person when updated last is smaller than the exit distance, the monitoring processing unit 38 estimates that the person of interest has exited the off-site area. On the other hand, if the exit distance is equal to or less than the approach distance, the monitoring processing unit 38 estimates that the person of interest has moved to the indoor area.
The monitoring processor 38 updates the unupdated tracking data according to the estimated destination area (step S302). Specifically, the monitoring processing unit 38 rewrites the previous location area information with the code of the partial area stored in the current location area information. If the destination is estimated to be an off-site area, the monitoring processing unit 38 sets an identification code for the off-site area in the current location area information. On the other hand, if the destination is estimated to be the indoor area, the monitoring processing unit 38 sets the indoor area identification code in the current location area information. In addition, the monitoring processing unit 38 rewrites the area transition time with the current scanning time.
Thereafter, the monitoring processing unit 38 refers to the authority information included in the tracking data and specifies the authority for the person of interest (step S303). Alternatively, the monitoring processing unit 38 may specify the authority corresponding to the identification code of the tag included in the tracking data as the authority of the person of interest by referring to the authority table. Then, the monitoring processing unit 38 reads an event table corresponding to the specified authority from the storage unit 37. The monitoring processing unit 38 refers to the read event table and determines whether or not an event occurs according to the updated combination of the previous location area and the current location area (step S304). When the event does not occur (No at Step S304), the monitoring processing unit 38 ends the unupdated tracking data update process.
On the other hand, when some event occurs (step S304—Yes), the monitoring processing unit 38 executes processing according to the event defined in the event table (step S305). Thereafter, the monitoring processor 38 ends the unupdated tracking data update process.

Here, an example of an event table for each authority is shown below. Table 1 is an event table for an authorized person, Table 2 is an event table for a restricted authorized person, and Table 3 is an event table for an unauthorized person.

In each table, the previous location area is shown in each column of the leftmost column. In addition, the current location area is shown in each column in the top row. That is, the combination of the previous location area shown in the leftmost column and the current location area shown in the uppermost row is a transition type representing the movement history of the person.
In each column of the other table, a person who pays attention to the current location area indicated in the uppermost column in the same row as that column from the previous location indicated in the leftmost column in the same column as that column Shows the contents of the event when moved. In the column where the previous location area and the current location area are the same, the content of the event when the stay of the person of interest in the area is detected is shown. A blank column indicates that no event is set for the transition type corresponding to the column. For convenience, each column of the above table shows a word indicating the content of the event, but in reality, a code corresponding to the word is stored in the storage unit 37.

The event includes not only a determination process for determining whether or not a person in the monitoring area is a suspicious person, but also an alarm process for performing various warnings including a simple notification associated with the user entering and exiting the monitoring area.
For example, if the person of interest is a permitter, the previous location area is an off-site area, and the current location area is a service area, the event that occurs is “return home 1”. For example, as the “return home 1” process, the monitoring processing unit 38 reads an audio signal (for example, “return home”) associated with the code of the “return home 1” process from the storage unit 37, and uses the audio signal. It transmits to the sensor terminal 2 installed near the area. Furthermore, if the person of interest is a permitter, and the previous location area is a service area and the current location area is an indoor area, the event that occurs is “return home 2”. The monitoring processor 38 increments the number of people in the building by 1 as the “return home 2” process.

In addition, if the person of interest is a permitter, the previous location area is an indoor area, and the current location area is a service area, the event that occurs is “outing 1”. For example, as the “outing 1” process, the monitoring processing unit 38 reads an audio signal (for example, “Come here”) associated with the code of the “outing 1” process from the storage unit 37 and uses the audio signal. It transmits to the sensor terminal 2 installed near the area. Furthermore, if the person of interest is a permitter, the previous location area is a service area, and the current location area is an off-site area, the event that occurs is “outing 2”. In this case, the monitoring processing unit 38 decrements the number of people in the building by 1 as the “outing 2” process.
Furthermore, if the person of interest is a non-permitted person, if the previous location area is an indoor area and the current location area is a service area, the event that occurs is “tag confirmation”. In other words, there is a possibility that a person who has left the building forgets to have a permission tag and goes out of the building, that is, a person who should originally be a permitted person, and makes an announcement of forgetting the tag. For example, as the “tag confirmation” process, the monitoring processing unit 38 reads an audio signal (for example, “please go with a tag”) associated with the code of the “tag confirmation” process from the storage unit 37, and The audio signal is transmitted to the sensor terminal 2 installed near the service area.
Furthermore, if the person of interest is a non-permitted person and the previous location area is an off-site area and the current location area is a service area, the event that occurs is “visitor”. For example, as the “visitor” process, the monitoring processing unit 38 reads an audio signal (for example, “If you are interested, please press the intercom”) from the storage unit 37 and reads the voice signal. The audio signal is transmitted to the sensor terminal 2 installed near the service area.

In addition, if the person of interest is a non-permitted person or a restricted permitter, the previous location area is an off-site area, and the current location area is a restricted area or a prohibited area without an entrance from the off-site area, the event that occurs is “ A suspicious alarm. That is, the monitoring processing unit 38 determines that the person of interest is a suspicious person who has illegally entered the monitoring area without passing through the entrance / exit. Therefore, the monitoring processing unit 38 determines that the person of interest is a suspicious person as the “suspicious alarm” process, and for example, an audio signal (for example, a “suspicious person” associated with the code of the “suspicious alarm” process from the storage unit 37. Discover! Please leave the site immediately ") and read the audio signal to the sensor terminal 2 closest to the current position of the person of interest. In addition, the monitoring processing unit 38 notifies the user who is occupying the building via the monitor 32 or the speaker 31 that a suspicious person has been detected. Further, the monitoring processing unit 38 displays an image captured by the camera 23 acquired from the sensor terminal 2 closest to the current position of the person of interest on the monitor 32, and outputs an audio signal collected by the microphone 24 from the speaker 31. May be. When the user performs a notification operation via the operation unit 33, the monitoring processing unit 38 notifies the monitoring center device 6 of an abnormality. When the “suspicious alarm” process for the same person is continuously performed for a predetermined period (for example, 1 minute), the monitoring processing unit 38 sends the monitoring center device 6 to the monitoring center apparatus 6 even if no user operation is performed. Abnormalities may be reported.
Similarly, when the person of interest is a restricted permitter, and both the previous location area and the current location area are prohibited areas, that is, when the person is staying in the prohibited area for a certain period of time, the event that occurs is “suspicious alarm”. It is.
Furthermore, this “suspicious alarm” process is performed when the target person is a non-permitted person, the previous location area is a restricted area, and the current location area is a prohibited area. Alternatively, it is executed even in a prohibited area.

Further, when the person of interest is a restricted permitter, the previous location area is a regular area or a restricted area, and the current location area is a prohibited area, the event that occurs is “warning 1”. That is, since the person of interest does not originally have the entry authority but may have entered the prohibited area by mistake, the monitoring processing unit 38 immediately stops warning without issuing a suspicious alarm. Therefore, the monitoring processing unit 38 performs the “warning 1” processing by, for example, an audio signal associated with the code of the “warning 1” processing from the storage unit 37 (for example “ The voice signal is transmitted to the sensor terminal 2 closest to the current position of the person of interest.
The “warning 1” process is also executed when the person of interest is a non-permitted person, the previous location area is a service area, and the current location area is a prohibited area.
Furthermore, when the person of interest is a non-permitted person, the previous location area is a service area, and the current location area is a restricted area, the event that occurs is “warning 2”. This “Warning 2” process is the same as the “Warning 1” process, except for the contents of the corresponding audio signal (for example, “This is a prohibited area from here. Please turn back”).
Even when the “warning 1” process and the “warning 2” process are executed, the monitoring processing unit 38 monitors the image captured by the camera 23 acquired from the sensor terminal 2 closest to the current position of the person of interest. An audio signal displayed on the microphone 32 and collected by the microphone 24 may be output from the speaker 31.

Further, when the person of interest is a restricted permitter or a non-permitted person, the previous location area is an area other than the indoor area, and the current location area is an indoor area, the event that occurs is an “intrusion alarm”. Therefore, as the “intrusion alarm” process, the monitoring processing unit 38 determines, for example, that the person of interest is a suspicious person, and, for example, from the storage unit 37, the audio signal (for example, “ Intrusion abnormality occurred! ”), The sound signal is notified from the speaker 31, the intrusion abnormality is displayed on the monitor 32, and the user in the building is notified that an intruder has been detected. To do. In addition, the monitoring processing unit 38 issues an abnormality report indicating that an intrusion abnormality has occurred to the monitoring center device 6.
However, if the previous location area is a service area, there is a possibility of visitors. Therefore, for example, the monitoring processing unit 38 does not execute the “intrusion alarm” process if an operation for permitting admission is performed before a predetermined time (for example, 20 seconds) via the operation unit 33. May be.

In this way, even if a person enters a specific partial area, the event that occurs varies depending on the partial area of the movement source. Thereby, the security system 1 can accurately distinguish a person who temporarily enters the monitoring area for a valid reason, such as a delivery person or a meter reader, from a suspicious person, and can execute an appropriate event for the entry. .
In particular, when a person enters the restricted area through the service area, the person may have a legitimate reason such as meter reading. Therefore, even if the person who entered the restricted area from the service area is a non-permitted person, the security system 1 does not immediately become a suspicious person. On the other hand, it is usually not possible to enter directly from outside the site into a restricted area where there is no entrance for a legitimate reason, and there is a high possibility of entry by an unauthorized person. Therefore, even when entering the same restricted area, if the security system 1 detects a person who has directly entered the restricted area from outside the site, the security system 1 immediately sets the person as a suspicious person.
Even if a person enters the surveillance area, if the person enters from the inside, it is estimated that the person originally has a legitimate authority, such as the user himself or a visitor. Therefore, unlike entering the monitoring area from outside the site, the security system 1 does not determine that the person is a suspicious person even if a person entering the monitoring area from the indoor area is detected.
In addition, even if an unauthorized person enters the prohibited area, the unauthorized person may have entered by mistake if entering from a service area where temporary entry is permitted Therefore, the security system 1 does not immediately become a suspicious person but keeps a warning. On the other hand, when entering from a restricted area that is a warning target, there is a high possibility of entry by a person with an unauthorized intention, so the security system 1 immediately makes the person a suspicious person.

  As described above, the security system according to one embodiment of the present invention is whether or not the person who entered the monitoring area is a suspicious person depending on the movement history in the monitoring area and the authority set for the person. Determine. Therefore, this security system can accurately detect a suspicious person and give a notification or warning before an illegal intrusion into the building occurs, and can prevent an illegal intrusion into the building. Furthermore, this security system can prevent misidentification of a suspicious person's detection falsely because a person who temporarily enters the premises for a legitimate reason, such as a delivery person or meter reader, can be prevented from being erroneously recognized as a suspicious person. it can.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to these embodiments. For example, in order to determine the authority to be set for a person in the monitoring area, the monitoring terminal checks the face of the person in the image taken by the camera of the sensor terminal with the face of the user registered in advance. May be. If the monitoring terminal determines that the face of the person in the captured image matches the face of any user registered in advance, the monitoring terminal determines that the person is an authorized person or a restricted authorized person. On the other hand, if the monitoring terminal determines that the face of the person shown in the photographed image does not match the face of any user registered in advance, the person is regarded as a non-permitted person. In this modification, in order to perform face matching, for example, any of various known face matching processes can be employed. In this case, the sensor terminal may not have a tag reader.
In addition, the monitoring processing unit of the monitoring terminal receives the image received from the sensor terminal and captured by the camera of the sensor terminal, and the background image that is captured when there is no person in the monitoring area and is stored in the storage unit in advance. A person may be detected by extracting a change area on an image based on a background difference between the image and a frame difference between a plurality of images sequentially captured by a camera. In this case, the monitoring processing unit obtains the position in at least one monitoring area in the change area from the distance measurement data of the sensor as described above, and sets the position as the position of the detected person.

  Further, each sensor terminal may be configured to perform a part of processing in the monitoring processing unit of the monitoring terminal. For example, each sensor terminal stores the installation position coordinates of its own terminal in the monitoring area, the reference direction of the scanning range of the sensor, map information, etc., and the control unit of each sensor terminal performs distance measurement by the sensor of the sensor terminal itself The position of the object in the monitoring area is calculated from the data, the installation position coordinates of the terminal, and the reference direction of the scanning range of the sensor. And the control part of each sensor terminal detects the person in the monitoring area based on the calculation result of the position of the object or the calculation result of the position of the object by the sensor of the other adjacent sensor terminal and the map information, Identify the location. Further, the control unit of each sensor terminal specifies a partial area where a person in the monitoring area is located. Each sensor terminal transmits a detection signal indicating that a person is detected in the monitoring area, the position of the person, and an identification code of the partial area where the person is located to the monitoring terminal.

  In addition, the permission tag and the restriction tag may store authority information representing authority regarding entry into the monitoring area in a built-in memory. In this case, when the permission tag and the restriction tag receive the question signal from the sensor terminal, the authorization tag is returned together with the identification information of the tag in the response signal. Then, the sensor terminal extracts the tag identification code and the authority information from the response signal and transfers them to the monitoring terminal. The monitoring terminal manages the authority information of the person in the monitoring area using the received authority information.

In addition, the monitoring terminal is not limited to the inside of the building surrounded by the monitoring area, and may be installed in another place. Alternatively, the monitoring terminal may be a terminal carried by the user. In this case, for example, a relay device is installed in a building in the monitoring area. This relay apparatus has an interface circuit for communicating with each sensor terminal and a wireless interface circuit for wirelessly communicating with a monitoring terminal carried by the user, and relays information from each sensor terminal to the monitoring terminal. Send.
As described above, those skilled in the art can make various modifications in accordance with the embodiment to be implemented within the scope of the present invention.
