The interrelationship determination unit 55c, the impersonation detection unit 55d, and the suspicious person monitoring unit 55e are caused to execute corresponding processes.

  The security guard management unit 55a is a processing unit that manages security guards by registering information about security guards in the security guard management data 54a. In addition, based on the arrangement and schedule of the guards indicated in the guard management data 54a, an instruction such as replacement is transmitted to the guard terminal apparatus 40.

  The security control unit 55b is a processing unit that controls security in a security area by a fixing device such as the monitoring camera 11 or a security guard. The security control unit 55b registers, in the security history data 54b, image data captured by the monitoring camera 11, detection results by other fixed devices, various information received from the security guard terminal device 40, and the like.

And prevent. It should be noted that the detected abnormality, the countermeasure to the abnormality and the result thereof are also registered in the security history data 54b.

  Furthermore, the security control unit 55b operates as an acquisition unit that acquires the position information and acceleration of the security guard transmitted from the security guard terminal device 40 as information related to the behavior of the security guard and registers the information in the security history data 54b.

  The interrelationship determination unit 55c is a processing unit that determines the interrelationship of information regarding the behavior of the guards acquired by the security control unit 55b. Specifically, using the position information and the acceleration of the guard transmitted from the guard terminal device 40, the relation between the position relation and the acceleration of each guard is determined.

  The impersonation detection unit 55d operates as a detection unit that detects impersonation of a third party by a third party based on the correlation determined by the correlation determination unit 55c. Specifically, when it is indicated by acceleration or the like that a specific security guard has taken a different movement from the security guards around, the specific security guard can be impersonated by a third party, that is, a suspicious person. It will be detected as having sex.

  For example, when the speed or acceleration of a specific guard is less than or equal to a predetermined threshold and the speed or acceleration of a plurality of guards located in the vicinity exceeds the predetermined threshold, the spoofing detection unit 55d Detect that there is a possibility of spoofing by a third party.

  The situation where the speed or acceleration of multiple security guards in the vicinity exceeds a predetermined threshold suggests that an anomaly affecting the wide area of the security zone has occurred and that each security guard is being forced to take security measures. This is because a guard who has recognized such an abnormality but has no change in speed or acceleration can be assumed to have not taken any security measures. Also, when the speed and acceleration exceed the threshold values as with other security guards, if the vectors are different, it can be estimated that not only security measures have not been taken, but also malicious actions have been taken. In addition, the behavior of each guard in the event of an abnormality affecting the wide area of the guard area is determined in advance, and after the occurrence of the abnormality is detected by the behavior of each guard, the guard who has not performed that action It may be detected that there is a possibility of impersonation.

  In addition to speed, acceleration, and vectors, other information may be used to detect impersonation. For example, when it is suggested that an abnormality affecting a wide area has occurred, it is monitored whether a report or a report has been made to the management device 50 from a security guard. As a result, if there is no report or contact from a guard who has taken a different action from other guards, there is a high possibility that the guard will be spoofed by a suspicious person.

  The suspicious person monitoring unit 55e is a processing unit that monitors a person with the possibility of impersonation detected by the impersonation detection unit 55d as a suspicious person. The suspicious person is monitored by taking an image with the monitoring camera 11 and acquiring information from the guard terminal 40 of the suspicious person.

  The monitoring camera 11 captures the suspicious person by identifying the monitoring camera 11 located in the vicinity from the position information of the guard terminal device 40 of the suspicious person so that the suspicious person enters the imaging range of the specified monitoring camera 11. This is done by sending a control instruction to. The suspicious person monitoring unit 55e can track and monitor the behavior of the suspicious person by registering and storing the imaging result of the monitoring camera 11 in the suspicious person monitoring data 54c. Note that the guard terminal device 40 of the guard located near the suspicious person may be identified, and the suspicious person may be imaged by the identified guard terminal device 40.

  Information acquisition from the suspicious person's guard terminal device 40 is performed by transmitting a user's monitoring command to the suspicious person's guard terminal device 40. Upon receiving the monitoring command, the security guard terminal device 40 collects the imaging result of the camera 31, the sound collection result of the microphone 32, the operation history of the security guard terminal device 40 while keeping it secret to the user, and transmits it to the management device 50. . The suspicious person monitoring unit 55e registers and accumulates these pieces of information in the suspicious person monitoring data 54c, so that what the user is looking at, what kind of conversation is being performed, and what kind of operation is performed. It can be tracked and monitored.

  Further, the suspicious person monitoring unit 55e functions as a notification unit that performs a predetermined notification to the guard terminal device 40 possessed by one or more guards based on the detection result by the spoofing detection unit 55d. The guard who has confirmed the notification by the guard terminal device 40 can take an action according to the notice and collect information on the suspicious person or deal with the suspicious person by the action.

  Specifically, the suspicious person monitoring unit 55e performs a predetermined notification for instructing the guard terminal device 40 possessed by one or more guards located in the vicinity of the suspicious person. By receiving this notification and guarding the guard, it is possible to cope with the prevention of suspicion by the suspicious person and the preparation and execution of various crimes that abuse the authority of the guard. Moreover, you may share the information regarding a suspicious person with another guard, or may increase the number of guards.

  In addition, the suspicious person monitoring unit 55e can also notify the guard terminal device 40 possessed by one or more guards located near the suspicious person to instruct contact with the suspicious person. If the guard comes into contact with the suspicious person in response to this notification, it is possible to prevent the suspicious person from obstructing the guard, and the guard terminal device 40 possessed by the contacted guard can capture the suspicious person and acquire sound. Is possible.

  Furthermore, the suspicious person monitoring part 55e can also notify the guard terminal device 40 possessed by the suspicious person to instruct contact with other guards. If the suspicious person comes into contact with other guards in response to this notification, it is possible to prevent the suspicious person from obstructing the guards, etc. Audio can be acquired.

  Next, the process procedure concerning the impersonation detection of the guard terminal device 40 will be described.

The flowchart shown in FIG. 5 is repeatedly executed periodically in addition to the normal main flow by the guard terminal device 40.

  First, the information collection part 46a of the guard terminal device 40 acquires acceleration from the acceleration sensor 37 (step S101), and acquires position information from the GPS unit 33 (step S102). The collection information transmission unit 46c transmits the acquired acceleration and position information to the management device 50 (step S103).

  Thereafter, the command processing unit 46d determines whether or not a monitoring command has been received from the management device 50 (step S104). If the monitoring command is received, the command processing unit 46d sets the user as a monitoring target (step S105). The instruction processing unit 46d starts collecting various types of information in order to monitor the security guard who is the user by setting the monitoring target. The collected information is transmitted to the management apparatus 50 as needed by the collected information transmission unit 46c.

  When the monitoring command has not been received (step S104; No), the command processing unit 46d determines whether a notification from the management device 50 to the user has been received (step S106). If the notification to the user is received (step S106; Yes), the command processing unit 46d outputs the received notification using the display operation unit 42 or the earphone 34 (step S107), and the process is terminated. If the notification to the user has not been received (step S106; No), the process is terminated as it is.

  Next, a processing procedure for spoofing detection of the management apparatus 50 will be described. FIG. 6 is a flowchart illustrating a processing procedure for spoofing detection of the management apparatus 50. The flowchart shown in FIG. 6 is repeatedly executed periodically in addition to the normal main flow by the management apparatus 50.

The correlation determining unit 55c determines the correlation between guards using the information acquired by the security control unit 55b (step S202). And the impersonation detection part 55d detects the impersonation to the guard by the third party based on the mutual relation determined by the correlation determination part 55c (step S203).

  If a person pretending to be a security guard is not detected (step S204; No), the process is terminated as it is. On the other hand, if a person pretending to be a security guard is detected (step S204; Yes), the suspicious person monitoring unit 55e registers the person as a suspicious person in the suspicious person monitoring data 54c (step S205). Monitoring is executed (step S206), and the process is terminated. As described above, the suspicious person is monitored using the imaging by the monitoring camera 11, the acquisition of information from the guard terminal apparatus 40 of the suspicious person, and the notification to the guard terminal apparatus 40.

  Next, a modification of impersonation detection will be described. The detection of impersonation is not limited to actions such as the speed and acceleration of the guard, but can also be performed using information about the body of the guard, for example, the heart rate.

In FIG. 7, the guard terminal device 40 carried by the guards G <b> 1 to G <b> 2 is connected to the heart rate sensor attached to the body of the guard, and transmits the position information and the heart rate of the guard to the management device 50. doing.

  The management device 50 determines the mutual relationship between the guards using the position information and the heart rate received from the guard terminal devices 40 of the guards G1 to G2 (S1), and the heart rate increases due to the approach of other guards. The detected guard G2 is detected as spoofing by a suspicious person (S2). Then, the detected guard G2 is monitored as an appropriate person for impersonation (S3).

  FIG. 8 is a flowchart showing a processing procedure of impersonation detection using a heart rate. First, the security control unit 55b of the management device 50 acquires the position information and heart rate of the guards transmitted from each guard terminal device 40 (step S301). If there is a guard whose heart rate is equal to or greater than the threshold (step S302; Yes), the correlation determining unit 55c determines whether another guard is present in the vicinity of the guard (step S302). S303).

  When the heart rate is equal to or lower than the threshold (step S302; No), or when no other guard is present in the vicinity (step S303; No), the impersonation detection unit 55d ends the process as it is.

  On the other hand, if the heart rate is equal to or greater than the threshold value and another guard is located nearby (step S303; Yes), the impersonation detection unit 55d determines that there is a possibility of impersonation (step S304), and performs processing. finish. In addition, the security guard determined to have the possibility of impersonation becomes the monitoring target thereafter.

  As described above, in the present embodiment, the security guard terminal device 40 is carried by a plurality of security officers in charge of security in a predetermined security area, and the management device 50 performs actions or actions of each security guard from the security guard terminal device 40. Since it is configured to acquire information on the body and detect impersonation of the security guard by a third party based on the behavior of the acquired security guards or the correlation between the information on the body, there are many third parties When the guard area to be guarded is guarded by a plurality of guards, it is possible to efficiently detect impersonation of the guards.

  In addition, when the speed or acceleration of a predetermined guard is below a predetermined threshold and the speed or acceleration of a plurality of guards located in the vicinity of the guard exceeds the predetermined threshold, the predetermined guard is By detecting that there is a possibility of impersonation by a person, it is possible to detect impersonation based on the behavior of guards.

  Further, when the heart rate of a predetermined guard exceeds a predetermined threshold and another guard is located in the vicinity of the guard, it is detected that there is a possibility of spoofing by a third party. This makes it possible to detect impersonation based on the physical condition of the guard.

  Moreover, when impersonation is detected, it is possible to cope with impersonation by performing a predetermined notification to the guard terminal device 40 possessed by one or more guards.

  Specifically, with respect to the guard terminal device 40 possessed by one or more guards located in the vicinity of the guard whose spoofing is detected among the guards in charge of guarding a predetermined guard area. A predetermined notification for instructing vigilance can be performed. In addition, a predetermined notification instructing contact with other guards is given to the guard terminal device 40 possessed by the guard whose spoofing is detected among a plurality of guards in charge of guarding a predetermined guard area. It is also possible to do this.

  In this embodiment, the GPS unit 33, the acceleration sensor 37, the heart rate sensor, and the like are connected to the guard terminal device 40 as an example. However, the GPS unit 33 and the acceleration sensor are connected to the guard terminal device 40. 37, may be implemented with a configuration incorporating a heart rate sensor or the like.

  In this embodiment, the case of detecting impersonation of a security guard was described as an example. However, the present invention can also be applied to detection of impersonation of a staff member, a security volunteer, or the like that supports a security guard. It is.

  Further, the present invention is not limited to acceleration, position information, heart rate, and the like, and it is also possible to detect impersonation by further using other information. For example, a track record of leaving the location during security, a track record of approaching a prohibited entry location during security, a track record of going to a specific location during breaks (out of duty hours), a track record of avoiding other security guards, Improving the detection of impersonation by using a combination of the results of power operation and function setting change operation of the security guard terminal device 40 during security, and rapid changes in acceleration when no abnormality has occurred. It can be carried out.

  Note that the configuration and operation shown in this embodiment are merely examples, and can be implemented with appropriate modifications. The information acquired for security and the acquisition method are not limited to the example of an Example, Arbitrary things can be used. Further, the analysis and use of the acquired information is not limited to the above embodiment.

  The security system, management device, and security method according to the present invention are suitable for efficiently detecting impersonation of a security guard when the security area where a large number of third parties are located is guarded by a plurality of security guards. ing.
