  However, even if a person who does not have the authority to contact the managed article is around the storage position of the managed article, it cannot be said that there is a high risk that fraud will generally occur. For example, if the manager is also in the vicinity or the managed article is not in the prescribed storage position in the first place, the risk of fraud is low. As described above, the risk of fraud varies depending on the storage state of managed articles and the presence / absence of a manager. On the other hand, even with the conventional technique, it is not possible to detect different risks depending on the storage state of managed articles and the presence / absence of a manager.

  The present invention has been made in view of the above, and an object of the present invention is to detect a risk that an article requiring security management is illegally taken out or used.

In order to solve the above-mentioned problems and achieve the object, the detection device according to the present invention has a person ID for identifying a person who can enter a predetermined monitoring range including a predetermined storage position of a managed article, A storage unit that stores authority information that associates the authority regarding the contact of the person with the managed article;
A detection unit that detects that the managed article is stored at the storage position, and a proximity within a predetermined distance from the storage position at the time when the managed article is detected to be stored at the storage position. A person in the vicinity is detected, and the authority corresponding to the person ID acquired by the identification section in the authority information is referred to, and the person in the vicinity is the managed article. And an alarm unit that outputs an alarm when there is no authority to contact the.

  According to the present invention, it is possible to detect a risk that an article requiring security management is illegally taken out or used.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment. In the description of the drawings, the same parts are designated by the same reference numerals.

[System configuration]
FIG. 1 is a schematic diagram showing a schematic configuration of a system including a detection device 1 according to this embodiment. As illustrated in FIG. 1, a managed article O that requires security management is usually placed and stored in a predetermined storage position X. The detection device 1 according to the present embodiment executes a detection process described below to determine whether or not the managed article O is stored at the storage position X, and a person who has entered a predetermined monitoring range R including the storage position X. By monitoring h, the risk of unauthorized removal or use of the managed article O is detected.

[Configuration of detector]
As illustrated in FIG. 1, the detection device 1 is realized by a general-purpose computer such as a personal computer and includes an input unit 11, an output unit 12, a communication control unit 13, a storage unit 14, and a control unit 15.

  The input unit 11 is realized by using an input device such as a keyboard and a mouse, and inputs various instruction information such as processing start to the control unit 15 in response to an input operation by an operator. The output unit 12 is realized by a display device such as a liquid crystal display, a printing device such as a printer, and an alarm device.

  The communication control unit 13 is realized by a NIC (Network Interface Card) or the like, and controls communication between the control unit 15 and an external device such as various sensors via a telecommunication line such as a LAN (Local Area Network) or the Internet. To do.

  The storage unit 14 is realized by a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disc, and stores the authority information 14a. The storage unit 14 may be configured to communicate with the control unit 15 via the communication control unit 13.

  The authority information 14a is information in which a person ID that identifies a person who can enter the monitoring range R and an authority regarding contact with the managed article O are associated with each other. FIG. 2 is a diagram illustrating a data configuration of the authority information 14a. As illustrated in FIG. 2, the authority information 14a includes person authority information 14b in which a person ID and authority rank are associated with each other, and article authority in which an article ID identifying the managed article O and each authority rank are associated with each other. And information 14c.

  Here, the authority rank means a class of authority regarding contact with the managed article O, and a value indicating the class is set for each person. In the example shown in FIG. 2, as the person authority information 14b, an authority rank of R1 or R2 is set for each person. The authority rank is set in the person authority information 14b even when the person ID is unknown. In the example shown in FIG. 2, the case where the person ID is unknown is included in the "other" person IDs. Further, as the article authority information 14c, the content of each class of authority rank is preset for each managed article O. In FIG. 2, for example, for item 1, R1 is set to the item manager, and R2 is set to be inaccessible. Thereby, for example, it is understood that the authority regarding the contact of the person 2 having the authority rank R2 with the article 1 is not contactable.

  Returning to the explanation of FIG. The control unit 15 is realized by using a CPU (Central Processing Unit) or the like and executes a processing program stored in the memory. Thereby, the control unit 15 functions as the detection unit 15a, the identification unit 15b, and the alarm unit 15c, as illustrated in FIG.

  The detection unit 15a detects that the managed article O is stored in a predetermined storage position X. Further, the detection unit 15a detects the movement of the managed article O from the storage position X.

  For example, the detection unit 15a receives sensor data from a sensor including an RFID tag and an RFID antenna. In that case, the RFID antenna installed in the storage detects the entry and exit of the managed article O to which the RFID tag is attached. The detection unit 15a detects the movement of the managed article O from the storage position X by receiving the sensor data detected by the RFID. Further, the detection unit 15a manages the storage state of the managed article O, that is, whether or not the managed article O is stored in the storage position X, depending on whether or not the sensor data detected by the RFID is received. Thereby, the detection unit 15a detects that the managed article O is stored in the storage position X.

  Alternatively, the detection unit 15a obtains the image captured by the video sensor that captures the storage location X of the managed article O so that the managed article O is stored at the storage location X or the storage location of the managed article O. Movement from X may be detected. In that case, identification information such as a QR code (registered trademark) or a bar code is attached to the managed article O, and the video sensor photographs the managed article O together with the attached identification information such as the QR code or the bar code. Then, the detection unit 15a identifies the managed article O at the storage position X or detects the movement of the managed article O by comparing the images of the storage location X captured by the video sensor at different times. As a result, the detection unit 15a can detect that the managed article O is stored in the predetermined storage position X and the movement from the storage position X at low cost and with high accuracy.

  At the time when it is detected that the managed article O is stored in the storage position X, the identification unit 15b detects a person h in the vicinity within a predetermined distance from the storage position X, and detects the person h Get an ID. Further, the identification unit 15b detects a person h in the vicinity within a predetermined distance from the storage position X at the time when the movement of the managed article O from the storage position X is detected, and the person ID of the person h is detected. To get.

  Here, the processing timing of the identification unit 15b will be described with reference to FIGS. 3 and 4. The identification unit 15b performs an identification process of detecting the person h around the storage position X in the monitoring range R and acquiring the person ID of the person h according to the detection result of the detection unit 15a.

  Specifically, as illustrated in FIG. 3, it is detected that the managed article O is stored in the storage position X, that is, the continuation of the state where the managed article O is stored in the storage position X (storage state ON). At the designated time, the identification unit 15b identifies the person h in the vicinity of the storage position X in the monitoring range R.

  Further, as illustrated in FIG. 4, the movement of the managed article O from the storage position X, that is, the state transition from the storage state ON of the managed article O to the state not in the storage position X (storage state OFF) is detected. At time, the identification unit 15b identifies the person h who is in the vicinity of the storage position X in the monitoring range R.

  For example, the identification unit 15b uses the GPS information of the mobile terminal possessed by the person h, the beacon information received by the mobile terminal, and the like, as information indicating the position of the person h in the vicinity of the storage position X within the monitoring range R and The person ID for identifying this person h is detected.

  Alternatively, the identification unit 15b acquires the sensor data of the detection result by the image sensor installed in the vicinity of the storage position X and a plurality of sensors of different types such as beacons, and thereby the person of the person in the vicinity of the storage position X. It may be configured to obtain an ID. In that case, the identification unit 15b detects the same person by each sensor in advance at the same time, learns the relationship between the detection results by each sensor, and uses the learning result, the detection result by each sensor of the detection target person. Determine whether the same person belongs. As a result, the identification unit 15b can detect a person who is near the storage position X with low cost and high accuracy, and can acquire the person ID of this person.

  In the above case, each type may have a plurality of sensors. For example, a plurality of image sensors may be installed to capture the image near the storage position X. In this case, since the accuracy of the detection result by the video sensor is further improved, the identification unit 15b can detect the person in the vicinity of the storage position X with higher accuracy and acquire the person ID of the person.

  The alarm unit 15c refers to the authority corresponding to the person ID acquired by the identification unit 15b in the authority information 14a, and outputs an alarm when the person near the storage position X does not have the authority to contact the managed article O. To do. Specifically, the alarm unit 15c refers to the authority information 14a using the person ID acquired by the identification unit 15b, and when the authority regarding contact with the managed article O is inaccessible, the managed article O is illegally taken out. It outputs an alarm indicating that there is a high risk of use and security. For example, the alarm unit 15c causes the output unit 12 to display a message indicating a caution state.

  Note that the alarm unit 15c refers to the authority when the person ID is unknown in the authority information 14a even when the identification unit 15b cannot acquire the person ID of the person near the storage position X, and this person If the user has no authority to contact the managed article O, an alarm is output as a warning state. For example, when the detection accuracy of the person h is low, or when the detected person h does not correspond to any person ID registered in the authority information 14a, the identification unit 15b is near the storage position X. This corresponds to the case where the person h cannot be identified.

  Further, the alarm unit 15c outputs an alarm when none of the persons in the vicinity of the storage position X are managers of the managed article O and any one of them has no authority to contact the managed article O. You may do it. For example, this corresponds to the case where the person 2 and the person 3 each having the authority rank R2 are near the storage position of the article 1 of the authority information 14a illustrated in FIG. In this case, it is detected that the person with the authority rank of R1 who is the article manager for the article 1 is absent, and only the person with the authority rank R2 who cannot contact the article 1 is near the storage position. As a result, the warning state of the managed article O can be notified with higher accuracy.

  Further, the alarm unit 15c may instruct the alarm device installed in the place where the manager of the managed article O is to output the alarm sound. Alternatively, the message may be notified to the mobile terminal owned by the administrator. As a result, a warning is output to the manager of the managed article O. Therefore, it is possible to call the attention of the manager more effectively.

[Detection processing]
Next, with reference to FIG. 5, a detection process by the detection device 1 according to the present embodiment will be described. FIG. 5 is a flowchart showing a detection processing procedure.

Is performed (step S2).

  Next, the alarm unit 15c refers to the authority information 14a, and if the person h in the vicinity of the storage position X does not have the authority to contact the managed article O, it is determined to be in the alarm state (Yes in step S3), and the alarm is issued. Is output (step S4). When the alarm unit 15c determines that the alarm state is not set (step S3, No), the process returns to step S1. This completes a series of detection processes.

  As described above, in the detection device 1 of the present embodiment, the detection unit 15a detects that the managed article O is stored in the storage position X, and at that time, the identification unit 15b displays the storage position X. The person h in the vicinity within a predetermined distance from is detected, and the person ID of the person h is acquired. The alarm unit 15c refers to the authority corresponding to the person ID acquired by the identification unit 15b in the authority information 14a, and outputs an alarm when the person h in the vicinity does not have the authority to contact the managed article O. .

  As a result, the detection device 1 according to the present embodiment detects that the person h who is not authorized to contact the managed article O is in the vicinity of the stored position X while the managed article O is stored in the storage position X. it can. In this way, it is possible to detect the risk that the managed article O is illegally taken out or used.

  Alternatively, the detection unit 15a detects the movement of the managed article O from the storage position X, and at that time, the identification unit 15b detects a person h in the vicinity within a predetermined distance from the storage position X, The person ID of the person h is acquired. Further, the alarm unit 15c refers to the authority information 14a and outputs an alarm when the person h in the vicinity has no authority to contact the managed article O.

  As a result, when the managed article O moves from the storage position X, the detection device 1 can detect that the person h who is not authorized to contact is near the storage position X. In this way, it is possible to detect the risk that the managed article O is illegally taken out or used.

  Further, when the identification unit 15b cannot acquire the person ID of the person near the storage position X, the alarm unit 15c refers to the authority when the person ID is unknown in the authority information 14a, and this person is identified. If there is no authority to contact the managed article O, an alarm is output. Thereby, an outsider or the like can be detected.

  Further, the alarm unit 15c issues an alarm when none of the persons h in the vicinity of the storage position X are managers of the managed article O, and any one of them has no authority to contact the managed article O. Output. As a result, the warning state of the managed article O can be notified with higher accuracy.

  Further, the alarm unit 15c outputs an alarm to the manager of the managed article O. Therefore, it is possible to call the attention of the manager more effectively.

  Further, the detection unit 15a confirms that the managed article O is stored at the storage position X or is moved from the storage position X based on the image of the storage position X of the managed article O to which the identification information is attached. Detect. Accordingly, it is possible to detect that the managed article O is stored in the predetermined storage position X and the movement from the storage position X at low cost and with high accuracy.

  Further, the identification unit 15b uses the detection results of a plurality of different types of sensors installed in the vicinity of the storage position X to learn the relationship between the detection results of the same person being detected by each sensor in advance at the same time, and the detection is performed. By determining whether the detection result of each sensor of the target person is the same as the person ID detected by any of the sensors, the person ID of the person near the storage position X is acquired. As a result, the person ID of the person who is near the storage position X can be acquired with high accuracy at low cost.
