Next, a specific example of the alert strength plan value will be described. FIG. 6 is an explanatory diagram of a specific example of the alert strength plan value. In FIG. 6, the necessary alert strengths are associated with each other when the congestion degree of the security target area is “to 30 people”, “31 to 50 people”, and “51 people”. ing. The required alert strength is set as a range defined by the upper limit Bmax and the lower limit Bmin.

Specifically, when the congestion level is “˜30 persons”, the required alert strength upper limit Bmax is “3 persons” and the required alert strength lower limit Bmin is “1 person”. When the congestion level is “31 to 50 people”, the required alert strength upper limit Bmax is “3” and the required alert strength lower limit Bmin is “2”. When the congestion level is "51 or more", the required alert strength upper limit Bmax is "4" and the required alert strength lower limit Bmin is "3".

Next, a specific example of the placement control will be described. FIG. 7 is an explanatory diagram of a specific example of arrangement control. First, the actual alert strength has two values: the actual alert strength upper limit Amax and the actual alert strength lower limit Amin. The actual alert strength lower limit Amin is equal to the number of area guards (the number of area guards) in charge of the target security area. The actual alert strength upper limit Amax is the total of the number of area guards and the number of patrol guards located in the area to be guarded (the number of patrol guards in the area).

In the arrangement control, when the actual alert strength lower limit Amin exceeds the required alert strength upper limit Bmax, the fact that the alert strength is excessive is notified. This notification may be given to the person in charge of the control center 50.

If the actual alert strength upper limit Amax is less than the required alert strength lower limit Bmin, the fact that the alert strength is insufficient is notified. It is desirable that this notification be given to the area guard in addition to the person in charge of the control center 50.

Furthermore, if the actual alert strength upper limit Amax is less than the required alert strength lower limit Bmin and the difference between the actual alert strength upper limit Amax and the required alert strength lower limit Bmin is greater than or equal to a predetermined threshold value, a new security guard will be provided to guard the target area. Automatically add guards by assigning.

The automatic addition of the guards may be performed by referring to the guard status data 54a, identifying the guards who are the additional staffs, and transmitting a notice instructing the identified guards to go straight to the site. The guards who can be additional personnel include patrol guards located in other guarded areas, waiting guards, surplus area guards in other guarded areas, and the like. When the guards are automatically added, the guard state data 54a is updated, and the person in charge of the control center 50 is notified.

Next, a processing procedure of the control center 50 will be described. FIG. 8 is a flowchart showing the processing procedure of the control center 50. First, the area state determination unit 55b analyzes the image data acquired by the security target area information acquisition unit 51 from the surveillance camera 11 to estimate the total number of ordinary customers located in the security target area, and evaluates the degree of congestion. A congestion degree, which is a value, is obtained (step S101).

When the area state determination unit 55b calculates the congestion degree, the required warning strength calculation unit 55e calculates the required warning strength 54c using the congestion degree and the warning strength plan value 54b (step S102).

When the guard state management unit 55a acquires the guard state (step S103) and updates the guard state data 54a, the actual alert strength calculation unit 55f uses the updated guard state data 54a to calculate the actual alert strength. The current value of 54d is calculated (step S104).

The placement control unit 55g compares the required alert strength 54c with the actual alert strength 54d (step S105). As a result of the comparison, if the actual alert strength 54d does not deviate from the appropriate range (step S106: No), the process is ended as it is. On the other hand, if the actual alert strength 54d deviates from the proper range (step S106; Yes), the placement control unit 55g executes placement control for changing the guard state according to the comparison result (step S107), and the process. To finish.

Next, a case where there are a plurality of security target areas will be described. FIG. 9 is an explanatory diagram for a case where there are a plurality of security target areas. In FIG. 9, three security target areas, a security target area R1, a security target area R2, and a security target area R3 are shown. In this way, when there are a plurality of security target areas, a warning strength plan value, a required warning strength, and an actual warning strength are calculated for each of them. For example, in FIG. 9, the required alert strength upper limit of the security target area R1 is Bmax1, the required alert strength upper limit of the security target area R2 is Bmax2, and the required alert strength upper limit of the security target area R3 is Bmax3.

Here, the sum ΣBmax of the required alert strength upper limits is set to be equal to or less than the total number of guards. Therefore, for example, if the required alert strength is updated due to changes in the congestion level and the sum of the required alert strength upper limit exceeds the total number of guards, the alert strength plan value and required alert strength of each security target area are used. The necessary warning strength upper limit of each security target area is adjusted so that the sum ΣBmax is equal to or less than the total number of security guards.

In the above description, the case has been described as an example in which the congestion degree and the required alert strength are associated with each other, but the required alert strength can be associated with a factor other than the congestion degree. For example, the required alert strength may be set based on the schedule of the event.

FIG. 10 is an explanatory diagram for setting the required alert strength based on the event schedule. In FIG. 10, two areas, the inside of the event venue and the roads around the event venue, are set as the security target areas, and the time is "~18:00 (before the event)", the time "18:00-21:00 (during the event)", and the time " The required alert strength is set for three patterns of "21: 00-(after the event)".

First, for the time "~18:00 (before the event)" in the event venue, the required alert strength upper limit Bmax is "3" and the required alert strength lower limit Bmin is "1". Further, regarding the time "18:00 to 21:00 (during the event)" in the event venue, the required alert strength upper limit Bmax is "7" and the required alert strength lower limit Bmin is "5". Further, regarding the time “21:00-(after the event)” in the event venue, the required alert strength upper limit Bmax is “4 persons” and the required alert strength lower limit Bmin is “2 persons”.

For the time "~18:00 (before the event)" on the road around the event venue, the required alert strength upper limit Bmax is "5" and the required alert strength lower limit Bmin is "3". Also, regarding the time “18:00 to 21:00 (during the event)” on the road around the event venue, the required alert strength upper limit Bmax is “3 persons” and the required alert strength lower limit Bmin is “1 person”. Further, regarding the time “21:00 to (after the event)” on the road around the event venue, the required alert strength upper limit Bmax is “7 persons” and the required alert strength lower limit Bmin is “5 persons”.

As described above, the security system according to the present embodiment, for the security target area to be the security target, calculates the required security level indicating the required security level, and indicates the actual security level in the security target area. Since the actual security level is calculated and the security status is changed according to the result of comparison between the required security level and the actual security level, it is possible to perform flexible security control that is adapted to the situation of the security target area.

The required alert strength may be the number of cooperators required to guard the security target area, and the actual alert strength may be the number of cooperators who are guarding the security target area.

In the present embodiment, the case has been described as an example where a guard guards as a coordinator, but the present invention can also be applied to a case where a volunteer staff member etc. guards as a cooperator.

In addition, the number of responsible personnel in charge of the security target area is used as the lower limit of the actual alert strength, and the total of the number of responsible personnel and the number of other responders in the guarded area is used as the actual alert strength. Can be used as the upper limit of

Further, the required alert strength can be changed according to the degree of congestion of the security target area. In addition, when the lower limit of the actual alert strength exceeds the required alert strength, it is possible to notify that the alert strength is excessive. Further, when the upper limit of the actual alert strength is lower than the required alert strength, it is possible to notify that the alert strength is insufficient. Furthermore, when the upper limit of the actual alert strength is lower than the required alert strength and the difference between the upper limit of the actual alert strength and the required alert strength is equal to or more than a predetermined value, a new assigning agent is assigned to the guard in the target area. Can be done.

In the present embodiment, the case where the total number of ordinary customers located in the security target area is estimated from the imaging result of the surveillance camera 11 and used as the evaluation value indicating the degree of congestion has been described as an example. The evaluation can be performed by any method. Further, a factor other than the congestion degree such as an event schedule may be used, or a plurality of factors may be combined and used.

Although not described in this embodiment, it is desirable to set the alert strength plan value in consideration of static factors such as the area of the area to be guarded and the number of blind spots.

Further, it is not always necessary to use the congestion level, and it is possible to change the required alert strength using arbitrary information such as changing the required alert strength when there is a notification or when there is suspicious person information.

Further, a plurality of terminals for monitoring personnel may be connected to the control center 50 so that the plurality of monitoring personnel can monitor at the control center 50. With such a configuration, for example, when a guard is connected to the monitoring staff by telephone, all the monitoring staff terminals are set to the incoming state by the calling of the security staff, and the terminal for the monitoring staff who responds first and the security staff. All you have to do is make a call connection with the staff.

In addition, the face image of the operator or a person in the vicinity is acquired by the camera 31 of the security guard terminal device 40, the facial expression is analyzed to determine the urgency of the call, and when the urgency is high (tension, pain, confusion in the facial expression) If there are many), you can preferentially connect to the call.

In addition, when guarding is performed using volunteer staff or the like in addition to the guard, the terminal carried by the volunteer staff is made different from the guard terminal device 40, and the function can be restricted. Moreover, you may execute on each terminal as a different application program.

Further, in this embodiment, the detailed description of the acquisition of the position information of the guard is omitted, but the position information of the guard can be acquired by an arbitrary method other than the acquisition by the GPS unit 33. For example, the position may be measured indoors using a BLE tag or geomagnetism. In the case of performing position measurement by geomagnetism, the indoor position is estimated from the characteristic amount of the environmental magnetic field due to the magnetized steel frame, etc. by moving indoors with a terminal having a built-in magnetic sensor. Note that in indoor positioning by magnetic field, it is difficult to recognize the difference between layers because the position is estimated from the magnetic characteristic amount of the surrounding environment. Therefore, by combining with the SSID information of Wi-Fi installed in each place. The magnetic characteristics may be detected after specifying the hierarchy or area.

Further, the control center 50 and the security guard terminal device 40 may be able to display a map by attaching a symbol indicating the occurrence of an event to a layer (security target area) in which an event occurs. Further, when there are a plurality of layers, a symbol indicating the occurrence of an event can be added to the corresponding layer in the layer list.

Further, the control center 50 can receive and manage the registration of the security plan, identify the security officer based on the security plan, and provide information to the security officer.

Further, it is also possible to register the incident, which is contacted from the guard terminal device 40 to the control center 50 by a call, in the incident history by using the information of the caller and the position information.

Further, the control center 50 may be registered with the contact information to the related organizations such as police and fire departments, and the contact information of the related organizations may be referred to from the control center 50 and the guard terminal device 40 so that the contact can be made. .. At this time, the contact information of the nearest related organization may be selectable using the position information of the security guard terminal device 40.

Further, the position information of the caller may be registered as the position information of the event, and further, the position may be corrected when the position of the caller is different from the position of the event.

Further, when a security guard makes a call, it may be difficult to perform a complicated operation. Therefore, an earphone 34 or the like may be provided with an emergency call button. Further, it may be possible to make a report using a voice keyword.

In addition, the security guard terminal device 40 is provided with a timer function to manage the progress of the security guard's actions, and when it is detected that the progress of the security is slow, the safety confirmation of the security guards and the support of the security guards You may send a dispatch.

In addition, a plurality of security guards may be specified in advance to deal with the incident according to the content of the incident that has occurred. For example, multiple fire guards are required for initial fire extinguishing, paying personnel, liaison personnel, and guidance of related organizations, so handle an appropriate number of guards according to conditions such as report type, report area, time, and progress update. Send a notification.

In addition, when the guard who receives the coping notification cannot handle it, for example, when the guard sends a notification that the guard cannot handle to the control center 50, or when the coping notification is transmitted, a response is sent for a certain period of time. If there is not, the control center 50 may be configured to specify another security guard and send a coping notice. Further, for the guards who cannot deal with the problem, the countermeasure notice may be controlled not to be transmitted for a certain time (for example, about 5 minutes).

In addition, when the observer or the like contacts the whistleblower and determines that it is not necessary to deal with the transmitted handling notice, the cancellation notice may be sent to the guard who has sent the handling notice. .. In addition, when the guard who receives the coping notification and starts coping determines that the support is required, a support request may be made to the control center 50 and a coping notification may be additionally transmitted to the support guard. Good.

In addition, the guard terminal device 40 may be configured to automatically display a map indicating the position of the case when the handling notification is received, and reduce the operation of the guard.

Further, the control center 50 may notify the control center 50 of the countermeasure result from the guard terminal device 40, and the control center 50 may manage the result. The control center 50 manages incidents that are occurring or incidents that have been dealt with, and enables narrowing down by area or keyword and list output.

Further, it is preferable that the control center 50 stores details of the incident for each incident and an outline of the overall incident handling, and can output the file as a form.

Further, when the guard terminal device 40 and the control center 50 exchange messages, the position of the guard terminal device 40 can be managed by linking the position information with the exchange of the message. Further, it is desirable that the control center 50 retains a history of message exchanges.

In addition, the security guard terminal device 40 may store a security enforcement procedure so that the security guard can refer to it at any time.

Further, the security guard terminal device 40 and the terminals used by the volunteer staff and the like may be configured to be able to browse the facility map in which “AED”, “fire extinguisher”, “emergency exit” and the like are emphasized. Further, when a false report is repeatedly made from a terminal used by volunteer staff or the like, the operation of the terminal may be restricted.

Further, when the ID is distributed to a plurality of volunteer staff, the ID or password may be distributed from the leader or the like to each staff by using a QR code (registered trademark) or the like. Since it is assumed that the staff will be changed every day, and there are cases where even guards are on other than working days, it is not preferable that such a person who is not properly guarded can access the control center 50. Therefore, IDs and passwords that are valid only on that day are issued and distributed to the staff leader and security guard leader. At this time, it is troublesome to individually distribute the ID and the like to the staff and button tier, so the staff leader uses the QR code and the like to distribute the ID and password to each staff. Further, it may be possible to make a notification to the control center 50 only when it is possible to confirm that the user is at the site from the position information and the SSID.

Further, for example, it is also possible to receive information regarding an incident from a person concerned with the security destination such as an event organizer or a system of the security destination and take a countermeasure. It is also possible to judge the importance of an incident detected by the security system and notify the concerned parties of the security destination or the system of the security destination.

Further, the data may be received from an existing surveillance camera or the like, and may be used for incident detection and data browsing. Also, by transmitting BLE or Wi-Fi radio waves from the caller's terminal and receiving them with the directional radio wave capture provided in the surveillance camera, the orientation of the camera is changed so that the caller's position is displayed in the center of the camera. It may be configured to be possible.

Further, the security personnel who enter the important area may be configured to confirm whether or not the security officer is an authorized security officer by confirming biometric authentication or the like.

Further, the camera 31 connected to the security guard terminal device 40 may always capture an image, or may be configured to start capturing after the security guard arrives at the site in order to suppress communication amount and power consumption. Good. Furthermore, the resolution and frame rate of the wearable camera may be controlled so that a video important for monitoring can be efficiently acquired.

Further, each configuration and operation shown in the present embodiment is merely an example, and the present invention can be implemented by appropriately modifying the configuration and operation.
