In addition, the data to be transmitted to the monitoring center is sensor sensing data, and the image data is transmitted only for the part that needs to be confirmed. Therefore, the amount of data to be transmitted is small compared to the transmission of all image data. There is an effect that time and transmission cost can be reduced.

  The sensor 111 is a human sensor, for example, an infrared sensor that detects a person by the movement of heat, a shut-off sensor that detects a person by blocking infrared rays, an attitude sensor that detects a person by disturbance of electromagnetic waves, and a magnet These are various sensors for detecting abnormalities in the security area such as a magnet sensor for detecting opening and closing of the door. In the plurality of sensors 111a to 111n, a sensor ID is assigned to each sensor. Basically, it is arranged to pair with a later-described monitoring camera 112 so as to grasp the status of the monitoring area, but may be arranged independently.

  Here, the security state refers to a state in which when a security device receives a detection signal that is issued when an abnormality is detected by a sensor, an alarm that is known to be abnormal is transmitted to a monitoring center connected via a network. The security release state refers to a state in which an alarm notifying the abnormality is not transmitted to the monitoring center even when the security device receives the detection signal.

  The monitoring camera 112 captures an image of the monitoring area and is arranged in association with the sensor 111 so as to grasp the status of the monitoring area.

  The sensing information storage unit 113 stores sensing data sensed by the sensor 111 for each sensor. Here, the sensing data is data obtained by digitizing the detection signals detected by various sensors. For example, in the infrared sensor, the infrared detection signal detected by the sensor per unit time is digitized, and in the cut-off sensor, the time such as the infrared ray blocked per unit time is digitized as the sensing data. Become.

  The image information storage unit 114 stores image data captured by the monitoring camera 112 for each monitoring camera. Here, the image data may be stored as still image data or moving image data.

  The sensing information determination unit 115 determines whether or not the sensing data sensed by any one of the sensors 111 exceeds a preset threshold value.

  When the sensing information determination unit 115 determines that the sensing data exceeds the threshold value, the sensing information transmission unit 116 transmits the sensing data of all the sensors 111 stored in the sensing information storage unit 113 to the monitoring center 120. Is.

  The receiving unit 117 receives a transmission request for image data of the instructed monitoring camera 112 transmitted from the monitoring center 120.

  The image information transmission unit 118 edits the image data stored in the image information storage unit 114 in accordance with the transmission instruction of the image data received by the reception unit 117, and transmits the edited image data to the monitoring center 120. .

  The control unit 119 includes a sensor 111, a monitoring camera 112, a sensing information storage unit 113, an image information storage unit 114, a sensing information determination unit 115, a sensing information transmission unit 116, a reception unit 117, and image information transmission. Each unit of the unit 118 is controlled.

  The monitoring center 120 includes a receiving unit 121, a sensing information display unit 122, an area instruction unit 123, an image information request unit 124, an image information display unit 125, a control unit 126, and a sensor-linked database 1001. ing.

  The reception unit 121 receives the sensor data transmitted from the sensor information transmission unit 116 of the security device 110 or the monitoring camera 112 transmitted from the security device 110 in response to a request from the image information request unit 124 described later. Image data is received.

  The sensing information display unit 122 displays sensing data of all the sensors 111 received by the receiving unit 121 on a display monitor.

  The area instruction unit 123 receives an instruction of an area that the operator wishes to confirm the image data from the sensing data of all the sensors 111 displayed on the display monitor by the sensing information display unit 122.

  The image information request unit 124 requests the security device 110 for image data corresponding to the area of the sensing data instructed by the area instruction unit 123.

  The image information display unit 125 displays the image data of the monitoring camera 112 received by the receiving unit 121 on a display monitor.

  The control unit 126 controls the reception unit 121, the sensing information display unit 122, the area instruction unit 123, the image information request unit 124, and the image information display unit 125.

  The sensor linkage database 1001 defines the linkage between the sensor and the monitoring camera and the type of sensor. FIG. 2 is an explanatory diagram illustrating an example of a data configuration of the sensor-linked database. The sensor linkage database 1001 stores a sensor ID, a monitoring camera ID, and a sensor type in association with each other. For example, “1” is registered as the sensor ID, “1” as the monitoring camera ID, “magnet” as the sensor type, and the like. The sensor-linked database 1001 may be configured as the security device 110.

  Next, the monitoring process according to the present embodiment configured as described above will be described. FIG. 3 is a flowchart illustrating the procedure of the monitoring process according to the first embodiment.

  As a precondition for the description of the present embodiment, a monitoring area where the security device 110 is installed will be described. FIG. 4 is an explanatory diagram illustrating an example of a monitoring area where a security device is installed. The monitoring area 400 is in the premises of a private house, the security device 110 is installed, and sensors 111a to 111d and monitoring cameras 112a to 112e are connected to the security device 110. The security device 110 is connected to the monitoring center 120 via the network 130. It is assumed that the person 1 has moved from the off-site A through the gate 42 to the front entrance B, the building side C, and the backyard D.

  First, it is assumed that the security device 110 is in a security state when an operator presses a security button (not shown). The sensing information storage unit 113 stores the sensing data sensed by each sensor 111 together with the sensor ID (step S3001). The image information storage unit 114 stores the image data captured by each monitoring camera 112 in association with the sensing data of the sensor (step S3002). The sensing information determination unit 115 determines whether the sensing data exceeds a preset threshold value (step S3003). For example, in the case of an infrared sensor that detects a person by the movement of heat, an abnormality is determined when the cumulative amount of infrared detection exceeds a certain value (threshold).

  If it is determined that the sensing data exceeds the threshold value (step S3003: Yes), the sensing information transmission unit 116 transmits the sensing data for all sensors to the monitoring center 120 (step S3004). If it is determined that the sensed data does not exceed the threshold (step S3003: No), the sensed data sensed by each sensor 111 and the image data taken by each monitoring camera 112 are stored.

  Next, processing of the monitoring center 120 will be described. The receiving unit 121 of the monitoring center 120 receives the sensing data for all the sensors transmitted by the sensing information transmitting unit 116 of the security device 110 (step S3005). The sensing information display unit 122 displays the received sensing data for each sensor on the display monitor (step S3006).

  Here, the display on the display monitor of the sensing data of the sensor will be described. FIG. 5 is an explanatory diagram showing an example in which sensing data for each sensor is displayed on a display monitor. On the monitor screen 500, sensor ID 51, sensor type 52, and presence / absence 53 of linkage with the monitoring camera are displayed for each sensor, and the value or cumulative value of the sensed data detected by the sensor is indicated on the vertical axis, and the time is indicated on the horizontal axis. (54a to 54e). Furthermore, a predetermined threshold value is also displayed (55a to 55e). Considering the set position of the sensor, the threshold value is set high because the sensor 2 (sensor 111b in FIG. 4) arranged in front of the entrance often detects visitors such as customers and delivery companies. (55b). Further, since the sensor 4 (111d in FIG. 4) installed in the backyard rarely detects a visitor, the threshold is set low (55d).

  Specifically, sensor data displayed on the monitor screen 500 will be described. As described above, in FIG. 4, the person 1 passes through the gate 42 from outside the site A and moves to the front entrance B, the building side C, and the backyard D, so that the sensor 111b detects the person 1 at the entrance B. That is, the sensor 2 on the monitor screen 500 of FIG. However, since the threshold value is set high in consideration of a normal visitor, the sensing data does not exceed the preset threshold value and no alarm is issued.

  Next, the sensor 111c detects the person 1 at the building side C, that is, the sensor 3 on the monitor screen 500 in FIG. 5 is represented by a display between 58 and 59 of the sensing data 54c. Again, no warning is issued because the sensed data does not exceed a preset threshold.

  In the backyard D, the sensor 111d detects the person 1, that is, the sensor 4 of the monitor screen 500 in FIG. At 60, an alarm is issued because the sensed data exceeds a preset threshold value. When the alarm is issued, the above-described processing is performed, and the monitor image 500 of FIG. 5 is displayed on the display monitor.

  Returning to the flowchart of FIG. 3, the area instruction unit 123 receives an instruction of an area on the sensing data of each sensor displayed on the sensing information display unit 122 (step S3007). In step S3007, even if the sensing data of each sensor does not reach the threshold value before the alarm is issued, there is some reaction from the value of the sensing data (in the sensor 2, the range is 56 to 57, and in the sensor 3, the sensor 58 is 58. When the operator determines that there is a high possibility that the surveillance camera is photographing the person 1, a process of receiving a sensing data area instruction from the display monitor using a mouse or the like is performed.

  The image information request unit 124 transmits a transmission request for image data of the monitoring camera corresponding to the sensing data instructed by the area instruction unit 123 to the security device 110 (step S3008). Specifically, the monitoring camera ID corresponding to the sensor ID is acquired from the sensor-linked database 1001, and information such as the monitoring camera ID and the start time and end time corresponding to the sensing data area designated by the display monitor is transmitted. It will be.

  Again, the process in the security apparatus 110 is demonstrated. The receiving unit 117 receives a transmission request for image data transmitted from the image information requesting unit 124 of the monitoring center 120 (step S3009). In response to the image data transmission request, the image information transmission unit 118 edits the image data in the designated area (step S3010). Specifically, the image data of the monitoring camera ID acquired from the image information storage unit 114 is cut from the start time to the end time, and used as image data for transmission to the monitoring center 120. The image information transmission unit 118 transmits the edited image data to the monitoring center 120 (step S3011).

  Further, as processing in the monitoring center 120, the reception unit 121 receives image data transmitted from the security device 110 (step S3012), and the image information display unit 125 displays the transmitted image data on a display monitor. (Step S3013).

  As described above, in this embodiment, after the alarm is issued, the sensing data of all the sensors connected to the security device is transmitted to the monitoring center, and the sensing data displayed on the display monitor of the monitoring center is instructed. By doing so, it is possible to send only the image data corresponding to the monitoring area and time that are likely to have a suspicious situation before the alarm is issued to the monitoring center, and accurately and efficiently. It is possible to grasp the situation where an abnormality has occurred.

  In addition, the data to be transmitted to the monitoring center is sensor sensing data, and the image data is transmitted only for the part that needs to be confirmed. Therefore, the amount of data to be transmitted is small compared to the transmission of all image data. Time and transmission costs can be reduced.

It will be.

  The staying time dictionary database 8004 defines a staying time distribution value for each actor type in the monitoring area. The stay time distribution value refers to a stay time value that is a normal distribution obtained by sampling the time during which various actors stay in each area. This stay time distribution value can be used to determine the type of actor. In the present embodiment, the stay time distribution value includes 'stay time / median value' which is the stay time with the maximum probability of stay time obtained from the graph of the normal distribution of stay time and the probability of stay time of 95%. The stay time / width, which is the width from the median time, is used. FIG. 16 is an explanatory diagram showing an example of the data structure of the stay time dictionary database. The stay time dictionary database 8004 stores the monitoring area name, the actor type, the stay time / median, and the stay time / width in association with each other. For example, in the case of the above-mentioned conditions, when the monitoring area is “A” and the actor type is “household”, the stay time / median is “10” seconds and the stay time / width is “3” seconds. Has been.

  The action route learning database 8005 records the action route in which the actor actually acted, and is used as information for determining the type of the actor. FIG. 17 is an explanatory diagram illustrating an example of a data configuration of the action route learning database. The behavior route learning database 8005 stores the actor type and the behavior route in association with each other. For example, when the actor type “housekeeper” comes home, that is, passes through the gate from outside the site and enters the house from the entrance, “Nout, A, Nstay, B1, Nin” is stored as the action route. It will be.

  The stay time learning database 8006 records the time when the actor actually stays in the monitoring area, and is used as information for determining the type of the actor. FIG. 18 is an explanatory diagram showing an example of the data structure of the stay time learning database. The stay time learning database 8006 stores the monitoring area name, the actor type, and the stay time in association with each other. For example, if it takes 8 seconds for the actor type “housekeeper” to pass through the gate monitoring area, the area name is stored as “A” and the staying time as “8”.

  The penalty value database 8007 defines conditions and penalty values for calculating penalty values. FIG. 19A is an explanatory diagram of an example of a data configuration of a penalty value database. The penalty value database 8007 stores the time, current area name, previous area name, and penalty value (addition value) in association with each other. For example, when the time is “0:00 to 4:00”, the current area name is “B1”, and the previous area name is “A”, that is, when the housekeeper moves from the gate to the entrance at midnight when they do not go in and out very much Is stored as “20”.

  Furthermore, if the time is “0:00 to 4:00”, the current area name is “C”, and the previous area name is “B1”, that is, if you move from the entrance to the veranda at midnight, you are a suspicious person. Since the possibility increases, the penalty value is stored as “30”.

  On the other hand, if the time is “10: 0 to 17:00”, the current area name is “B1”, and the previous area name is “A”, that is, if the actor moves from the gate to the entrance, The penalty value is stored as “10”.

  Also, if the time is “10:00 to 17:00”, the current area name is “C”, and the previous area name is “B1”, that is, if the actor moves from the entrance to the veranda, the penalty value is set. “20” is stored. The penalty value database 8007 can calculate a penalty value that suits the current situation by storing different values depending on the monitored area, the behavior pattern of the householder, and the like.

  FIG. 19-2 is an explanatory diagram of an example of the data configuration of the penalty value database. The penalty value database 8007 stores time, current area name, previous area name, stay time / addition invalid time, stay time / addition time, and penalty value in association with each other. This database defines the penalty value when an actor stays in the same area. For example, when the time is “0: 0 to 4:00”, the current area name is “B1”, and the previous area name is “B1”, the stay time / addition invalid time is between “0 and 150” seconds. The penalty value is not added, but if it stays for “5” seconds after 150 seconds, the penalty value is stored as “5”.

  If the time is “10:00 to 17:00”, the current area name is “B1”, and the previous area name is “B1”, the stay time / addition invalidation time is set for “0 to 150” seconds, The penalty value is not added, but if it stays for “5” seconds after 150 seconds, the penalty value is stored as “2”.

  Next, the monitoring process according to the present embodiment configured as described above will be described. FIG. 20 is a flowchart illustrating the procedure of the monitoring process according to the third embodiment.

  First, in the flowchart of FIG. 20, it is assumed that the security device 810 is in a security state when an operator presses a security button (not shown). The sensing information transmitting unit 116 transmits sensing data for all sensors to the monitoring center 820 (step S20001). The image information storage unit 114 stores the image data captured by the monitoring camera 112 in association with the sensing data of the sensor (step S20002).

  Next, processing of the monitoring center 820 will be described. The monitoring center 820 receives the sensing data for all the sensors transmitted by the sensing information transmission unit 116 of the security device 810 (step S20003). The sensing information storage unit 821 stores the received sensing data together with the sensor ID (step S20004). The abnormality detection unit 822 recognizes the behavior pattern from the sensor ID and the sensed data, determines the actor type, and calculates the behavior evaluation value (step S20005). Details will be described later. The abnormality detection unit 822 determines whether or not the cumulative value of behavior evaluation values exceeds a predetermined danger value (step S <b> 20006).

  If it is determined that the cumulative behavior evaluation value does not exceed the danger value (step S20006: NO), the process returns to step S20003, and further receives the sensor ID and the sensed data. If it is determined that the cumulative behavior evaluation value has exceeded the danger value (step S20006: YES), the sensing information display unit 122 displays the received sensing data for each sensor on the display monitor (step S20007). Specifically, the sensing data is displayed on the display monitor in the same manner as in the first embodiment (see FIG. 4). The area instruction unit 123 receives an instruction of a designated area on the sensing data of each sensor displayed on the sensing information display unit 122 (step S20008).

  The image information request unit 124 transmits a transmission request for image data of the monitoring camera corresponding to the sensing data instructed by the area instruction unit 123 to the security device 810 (step S20009). Specifically, the sensor-linked database 1001 is searched, the monitoring camera ID corresponding to the sensor ID is acquired, and information such as the monitoring camera ID, the start time, and the end time is transmitted.

  Again, the process in the security apparatus 810 is demonstrated. The receiving unit 117 receives the transmission request for image data transmitted from the image information requesting unit 124 of the monitoring center 820 (step S20010). In response to the image data transmission request, the image information transmission unit 118 edits the image data in the designated area (step S20011). Specifically, the image data of the designated monitoring camera ID is cut from the start time to the end time, and is used as image data for transmission to the monitoring center 820. The image information transmission unit 118 transmits the edited image data to the monitoring center 820 (step S20012).

  Further, as processing in the monitoring center 820, the reception unit 121 receives the image data transmitted from the security device 810 (step S20013), and the image information display unit 125 displays the transmitted image data on a display monitor. (Step S20014).

  Next, an actor type determination process and an evaluation value calculation process in the abnormality detection unit 822 will be described. FIG. 21A to FIG. 21D are flowcharts illustrating the procedures of the action type determination process and the evaluation value calculation process in the abnormality detection unit.

  First, the sensor ID and the sensing data for each sensor recorded in the sensing information storage unit 821 are read (step S21001). Sensing data is analyzed for each sensor, and it is determined whether or not there is a person in the monitoring area where the sensor is installed (step S21002). For example, in the infrared sensor, it is determined that there is a person in the monitoring area when the cumulative value of the amount of infrared rays exceeds a certain amount.

  If it is determined that there is a person (step S21003: Yes), the sensor information database 8001 is searched using the sensor ID as a key, and an area name and an entrance / exit flag corresponding to the sensor ID are acquired (step S21004). It is determined from the entrance / exit flag corresponding to the sensor ID whether or not it is an entrance / exit in the house (step S21005). For example, when the sensor ID is “2”, the entrance / exit flag is “1 (exit / exit in the house)”, and therefore, the sensor ID is determined to be the entrance / exit in the house.

  If it is determined that the sensor that detects the person is an entrance to the house (step S21005: Yes), the sensor information database 1001 is searched to search for an exit sensor ID corresponding to the sensor ID (step S21006). . Sensing data corresponding to the entrance / exit sensor ID is searched to determine whether or not the actor has left the house within a certain period (step S21007). For example, in the present embodiment, the magnet sensor ID “5” for detecting the opening / closing of the door is installed at the entrance, but the magnet ID “2” at the entrance is used to detect the magnet within a certain period before detecting a person. If opening / closing of the door is detected with the sensor ID “5”, it is determined that the detected actor has come out of the house.

  When it is determined that the actor has left the house (step S21008: Yes), the actor is determined to be a family member (step S21009), and a new actor ID is assigned as the behavior of the new actor. The actor ID, the behavior route, the detection time, the staying time, and the family member flag are recorded in the actor information file (step S21010). Since it is determined that the action route is “Nin, B1” and the action person is a householder, “1” (housekeeper) is recorded in the housekeeper flag.

  In addition, when a family member is authenticated by possession of an IC tag or biometrics authentication, “1” is recorded in the family member flag of the behavior file of the actor who has been authenticated the family member. Become.

  Returning to step S21005, if it is determined that the sensor that detects the person is not the entrance to the house (step S21005: No), the process proceeds to step S21011. In step S21008, if it is not determined that the user has left the house (step S21008: No), the process proceeds to step S21011.

  The actor information file is searched, and the area name and detection time detected last time are acquired (step S21011). Specifically, the actor information file will be described with reference to the drawings. 9-1 is explanatory drawing which shows an example of the data of the actor memorize | stored in the actor information file. In FIG. 9A, the actor with the actor ID “001” is detected at “18:32:53” in the monitoring area A, the stay time is “0” seconds, and the action route is “Nout, A”. It moves from the off-site area to the gate, and data indicating that the evaluation value is “0” and the householder flag is “0” (not determined to be a householder) is recorded. When the process of step S21011 is performed using this example, “A” is acquired as the area name of the actor ID “001” previously detected, and “18:32:53” is acquired as the detection time.

  When it is determined that there is an area detected last time (step S21012: Yes), that is, when it is determined that a person exists in the site, the adjacent area database 8002 is searched and the area name detected last time The area name adjacent to is acquired (step S21013). It is determined whether the area detected this time is the same area as the previously detected area or an adjacent area (step S21014).

  When it is determined that the area detected this time is the same area as the area detected last time or an adjacent area (step S21015: Yes), as information on the actor corresponding to the actor information file, The actor ID, behavior route, detection time, and stay time are recorded (step S21016). For example, if the content of the actor information file in FIG. 9-1 is recorded and the area name detected this time is B1, it is present in the site from the previous detection area A according to the determination in step S21012. Therefore, the action route is “Nstay, B1”, the detection time is “18:32:58”, the stay time is “0” seconds, and the house flag is the previous house flag. The same value is recorded (see Fig. 9-2).

  Returning to step S21012, if it is determined that there is no previously detected area (step S21012: No), that is, if it is determined that there is no actor in the site, or in step S21015, adjacent areas When it is determined that it is not (step S21015: No), that is, when it is determined that the actor in the site is not detected, a new actor ID is assigned as the action of the new actor. The action ID, action route, detection time, stay time, and family flag (“0”) are recorded in the action information file (step S21017).

  In addition, in order to determine whether the detected actor is an already detected actor or a new actor, the staying time and distance information may be added as a criterion for determination. In the case where distance information is stored in the adjacent area database 8002, the moving speed may be calculated from the detection time and the distance information, and the moving speed may be used as a reference for identifying the type of the actor.

  Next, the process of determining the actor type will be described using the flowchart of FIG.

  First, the actor information file is searched (step S21018), and it is determined whether or not the housekeeper flag is 1 (determined to be a housekeeper) (step S21019). If it is determined that the housekeeper flag is not 1 (step S21019: No), the actor information file is searched to obtain the recorded action route of the currently acting actor, and the behavior route dictionary database. Whether or not it is a family member's behavior path is determined by searching 8003, obtaining a behavior route, and comparing it with the behavior route of the currently acting actor (step S21020). In order to determine the behavior route of the householder, the behavior route learning database 8005 may be used instead of the behavior route dictionary database 8003.

  If it is determined that the route is a family member's behavior route (step S21021: Yes), the residence time dictionary database 8004 is further searched using the behavior route detection area name in the behavior person information file as a key, and the family member's residence time. It is determined whether it is within (step S21022). Determining whether or not it is within the staying time of the family member is a value obtained by subtracting the staying time / width from the staying time / median value of the housekeeper in the corresponding area stored in the staying time dictionary database 8004. And the stay time / median value is added to the value obtained by adding the stay time / width. When it is determined that it is within the staying time of the householder (step S21023: Yes), or when it is determined in step S21019 that the householder flag is 1 (a householder) (step S21019: Yes). ), The actor information file is searched, and the previous evaluation value is recorded in the actor information file as the current evaluation value (step S21024). As a result, when the person is determined to be a family member, there is no addition of an action evaluation value. Possession or those who have been certified as biometrics, etc.), the behavioral evaluation value remains “0” and there is no addition, but the behavioral route, staying time, etc. are tracked Become.

  In order to determine the staying time of the householder, the staying time / median and the staying time / width may be calculated from the staying time learning database 8006 instead of the staying time dictionary database staying time dictionary database 8004 and used. .

  Returning to step S21021, if it is determined that the route is not a family member's action route (step S21021: No), or if it is determined that it is not within the residence time of the family member (step S21023: No), an actor information file And an action evaluation value is calculated from the previous evaluation value, the current detection time, the current area name, the previous area name, and the current area stay time (step S21025).

Here, the behavior evaluation value is obtained by Equation 1.

  Here, V: action evaluation value, n: detection order, t: time, E: evaluation value based on sensor detection data, Area (n): current area name, Area (n-1): previous area name, StayTime : Time spent in the current area, P: Other information (for example, an evaluation value can be set corresponding to detection data from a special sensor that senses contact with the doorknob).

  The current behavior evaluation value V (n) is obtained by referring to the above-described penalty value database 8007 to obtain the penalty value E under the current condition, and the previous behavior evaluation value V (n−1) is added to the current penalty value E. Is obtained by adding.

  Specifically, the content of the actor information file will be described. 9-4 is explanatory drawing which shows an example of the data of the actor memorize | stored in the actor information file as above-mentioned. The actor with the actor ID “003” is detected at the time “13:03:16” in the area “A”. At this time, since it is not a movement from the previous area and the stay time is “0” seconds, the added value (penalty value) is “0” and the action evaluation value is “0”.

  Next, the actor with the actor ID “003” is detected at the time “13:03:21” in the area “A”. This is detection in the same area as the previous area, but the stay time is also “5” seconds, and is within the stay time / addition invalid time of the penalty value database 8007 (see FIG. 19-2). Is “0”, added to the previous behavior evaluation value “0”, and the behavior evaluation value is “0”.

  In the third detection, the actor with the actor ID “003” is detected at the time “13:03:31” in the area “B1”. Since this is a movement from the previous area, at the time “10:00 to 17:00” in the penalty value database 8007 (see FIG. 19-1), the current area “B1” and the previous area “A” Therefore, the added value is “10”, added to the previous action evaluation value “0”, and the action evaluation value is “10”.

  Furthermore, another specific example is demonstrated using FIGS. 9-5. The actor having the actor ID “004” is detected at the time “2:11:53” in the area “A”. At this time, since the stay time is “0” seconds, not the movement from the previous area, the addition value is “0” and the action evaluation value is “0”.

  Next, the actor with the actor ID “004” is detected at the time “02:11:58” in the area “B1”. Since this is a movement from the previous area, since the current area “B1” and the previous area “A” at the time “0:00 to 4:00” in the penalty value database 8007, the added value is “ 20 ”, added to the previous behavior evaluation value“ 0 ”, and the behavior evaluation value is“ 20 ”.

  In the last detection, detection is performed at time “02:23:28” in the area “C”. Since this is a movement from the previous area, since the current area is “C” and the previous area is “B1” at time “0:00 to 4:00” in the penalty value database 8007, the added value is “ 30 ”, added to the previous behavior evaluation value“ 75 ”, and the behavior evaluation value is“ 105 ”.

  The behavior evaluation value thus obtained is recorded in the behavior information file (step S21026).

  Finally, returning to step S21003 in FIG. 21-1, the process in the case where it is determined that no person is detected (step S21003: No), that is, the process of ending the recording of the actor information file is shown in the flowchart in FIG. It explains using.

  If it is determined that no person is detected (step S21003: No), the actor information file is searched to determine whether there is an actor ID whose action route has not ended (step S21027). Specifically, it is determined whether or not there is data that has not ended because the action route is “Nin” or “Nout”.

  If it is determined that there is an actor ID whose action route has not ended (step S21028: Yes), the actor information file is searched, and the last detected area name, detection time, and entrance / exit flag are acquired. (Step S21029). Next, the current detection time is compared with the last detection time, and it is determined whether or not a predetermined time has elapsed (step S21030). If it is determined that a certain time has passed since the last detection time (step S21031: Yes), it is determined whether the last detected area is a doorway of a house (step S21032). That is, it is determined by whether or not the searched entrance / exit flag is 1 (entrance to / from the house).

  When it is determined that the last detected area is the entrance / exit of the house (step S21032: Yes), the entrance / exit sensor ID corresponding to the searched area is searched from the sensor linkage database 1001 (step S21033). Sensing data corresponding to the retrieved entrance / exit sensor ID is retrieved, and it is determined whether or not the user has entered the house within a certain period (step S21034). For example, in the present embodiment, the magnet sensor ID “5” for detecting the opening / closing of the door is installed at the entrance, but the magnet is detected within a certain period after the entrance sensor ID “2” detects a person. If opening / closing of the door is detected with the sensor ID “5”, it is determined that the detected actor has entered the house. If it is determined that the user has entered the house (step S21035), “Nin” is recorded as final data in the action route of the actor information file (step S21036). Data recorded in the actor information file is recorded in the behavior route learning database 8005 and the stay time learning database 8006 (step S21037).

  Returning to step S21032, if it is determined that the last detected area is not an entrance / exit of a house (step S21032: No), it is determined whether the last detected area is an entrance / exit outside the area (step S21038). That is, the determination is made based on whether or not the searched entrance / exit flag is 2 (exit / exit outside the monitoring area). If it is determined that the user has moved out of the monitoring area (step S21038: Yes), “Nout” is recorded in the action route of the actor information file (step S21039). Proceeding to step S21037, the data recorded in the actor information file is recorded in the behavior route learning database 8005 and the stay time learning database 8006 (step S21037). At the same time, the record of the target actor is deleted from the actor information file.

  Returning to step S21028, if it is determined that there is no actor ID whose action route has not ended (step S21028: No), the process returns to step S21031 and it is determined that a certain time has not elapsed since the last detection time. In the case (step S21031: No), the process returns to step S21035, and when it is determined that the actor has not entered the house (step S21035: No), the process returns to step S21038, and the area detected last is not an entrance / exit outside the monitoring area. If it is determined (step S21038: No), E jumps to the end of FIG.

  Thus, in this embodiment, by calculating the behavior evaluation value from the sensed data, it is possible to grasp the risk level of the actor in the monitoring area, and before actually entering the house, etc. Preventive measures such as threats can be taken. In addition, by sending the sensing data of all sensors connected to the security device to the monitoring center and instructing the sensing data displayed on the display monitor of the monitoring center, a suspicious situation before abnormality detection occurs. Only the image data corresponding to the monitoring area and time that are likely to be transmitted can be transmitted to the monitoring center, and the situation where the abnormality before the alarm is generated can be grasped accurately and efficiently.

  In addition, the data to be transmitted to the monitoring center is sensor sensing data, and the image data is transmitted only for the part that needs to be confirmed. Therefore, the amount of data to be transmitted is small compared to the transmission of all image data. Time and transmission costs can be reduced.

  Next, the monitoring process according to the present embodiment configured as described above will be described. FIG. 23 is a flowchart of a monitoring process procedure according to the fourth embodiment.

  First, in the flowchart of FIG. 23, it is assumed that the security device 2210 is in a security state when an operator presses a security button (not shown). The sense information storage unit 113 stores the received sensed sense data together with the sensor ID (step S23001).

  If it is determined that the cumulative behavior evaluation value exceeds the danger value (step S23004: YES), the sensing information transmitting unit 116 transmits sensing data for all sensors to the monitoring center 2220 (step S23005). ).

  Next, processing of the monitoring center 2220 will be described. The monitoring center 2220 receives the sensing data for all the sensors transmitted by the sensing information transmission unit 116 of the security device 2210 (step S23006).

Specifically, the sensor-linked database 1001 is searched, the monitoring camera ID corresponding to the sensor ID is acquired, and information such as the monitoring camera ID, the start time, and the end time is transmitted.

  Again, the process in the security device 2210 will be described. The receiving unit 117 receives a transmission request for image data transmitted from the image information requesting unit 124 of the monitoring center 2220 (step S23010). In response to the image data transmission request, the image information transmission unit 118 edits the image data in the designated area (step S23011). Specifically, the image data of the instructed monitoring camera ID is cut from the start time to the end time and used as image data for transmission to the monitoring center 2220. The image information transmission unit 118 transmits the edited image data to the monitoring center 2220 (step S23012).

  Further, as processing in the monitoring center 2220, the reception unit 121 receives the image data transmitted from the security device 2210 (step S23013), and the image information display unit 125 displays the transmitted image data on a display monitor. (Step S23014).

  As described above, in this embodiment, by calculating the behavior evaluation value from the sensed data, it is possible to grasp the risk level of the actor in the monitoring area, and before actually entering the house, etc. Preventive measures such as threats can be taken. In addition, by sending the sensing data of all sensors connected to the security device to the monitoring center and instructing the sensing data displayed on the display monitor of the monitoring center, a suspicious situation before abnormality detection occurs. Only the image data corresponding to the monitoring area and time that are likely to be transmitted can be transmitted to the monitoring center, and the situation where the abnormality before the alarm is generated can be grasped accurately and efficiently.

  Furthermore, the data to be transmitted to the monitoring center is sensor sensing data, and the image data is transmitted only for the part that needs to be confirmed. Therefore, the amount of data to be transmitted is small compared to the transmission of all image data, and the transmission is performed. Time and transmission costs can be reduced. In this embodiment, since the behavior evaluation value can be calculated in the security device, the sensing data can be transmitted to the monitoring center only when the behavior evaluation value of the actor exceeds the danger value, and the transmission time and transmission Cost can be reduced.
