Hereinafter, an embodiment of an asset monitoring system, an asset monitoring server, and an asset monitoring method according to the present invention will be described with reference to the drawings.
(Asset monitoring system)
FIG. 1 is a diagram for explaining the overall configuration of the asset monitoring system of the present embodiment. The illustrated asset monitoring system includes an asset monitoring server 101 and a positioning sensor 102 that provides the asset monitoring server 101 with information related to the position of the monitored object. The asset monitoring server 101 includes a data base (DB) 108 that stores information necessary for monitoring the monitoring target object 105 to be monitored.

  In the present embodiment, an IC tag 109 is attached to the monitoring target object 105. In the present embodiment, the IC tag 109 is an active wireless tag. The active IC tag 109 has a built-in battery and transmits radio waves. The positioning sensor 102 receives the radio wave transmitted by the IC tag 109 and reads the ID of the IC tag 109. Information regarding the ID of the read IC tag 109 is transmitted to the asset monitoring server 101 together with information specifying the read positioning sensor 102.

  The DB 108 of the asset monitoring server 101 stores information related to the monitoring target object 105 to which the IC tag 109 is attached. For example, when the monitoring target 105 is a device such as a personal computer (PC), the information is information such as a manufacturing number, a name of the device, an affiliation, and a person who has authority to take out. Such information is stored in association with the ID of the IC tag 109.

A range in which the positioning sensor 102 and the IC tag 109 can transmit and receive radio waves is referred to as a monitoring area a. A monitoring camera 103 is provided in the monitoring area a. The monitoring camera 103 is a so-called Web camera in which a captured image is transmitted to the asset monitoring server 101 via the network 107.
By combining the Web camera technology and the IC tag 109, the monitoring camera 103 automatically tracks the IC tag 109, images the monitoring object 105 to which the IC tag 109 is attached, and transmits it to the asset monitoring server 101. It becomes possible to do.

  Further, in the present embodiment, the mobile phone 104 is used as a communication terminal device for applying for the movement of the monitored object to the asset monitoring server 101. Note that the mobile phone 104 may be individually owned by the user, and the DB 108 may also store information when the user makes a contract with the mobile phone 104 and manage it by the asset monitoring server 101. .

  In addition, the movement of the monitoring object 105 applied to the asset monitoring server 101 by the mobile phone 104 is carried out by moving the monitoring object in the monitoring area a outside the monitoring area a, and the monitoring object 105 outside the monitoring area a. Refers to the movement made for return to move to the monitoring area a. The application for movement using the mobile phone 104 can be easily realized by the user operating the mobile phone 104 to send an email to the asset monitoring server 101 via the network 107.

Hereinafter, a mail signal transmitted for take-out is referred to as a take-out application signal, and a mail signal transmitted for return is referred to as a return application signal. Also, the take-out application signal and the return application signal are collectively referred to as an application signal.
Note that the present embodiment is not limited to a configuration in which an e-mail is transmitted to apply for take-out or return, but can also be realized by making a phone call. In this case, the transmitted telephone signal is a take-out application signal or a return application signal.
In the above configuration, the positioning sensor 102 and the IC tag 109 function as target position providing means, and the monitoring camera 103 functions as imaging means.

(Asset monitoring server)
FIG. 2 is a functional block diagram for explaining the configuration of the asset monitoring server 101. The asset monitoring server 101 includes a communication unit 201 that receives a take-out application signal and a return application signal transmitted from the mobile phone 104, and a detection unit that acquires the position of the application communication terminal device that has transmitted the application signal to the communication unit 201. 202. At this time, the mobile phone 104 that has transmitted the application signal becomes the application communication terminal device of the present embodiment.
In the detection unit 202 of the present embodiment, the position of the monitoring target 105 provided by the positioning sensor 102 and the IC tag 109 is also input, and the detection unit 202 uses the positioning sensor 102 and the monitoring camera 103 to monitor the mobile phone 104 and monitor. The position of the object 105 can be monitored at any time.

  Here, a specific example of the asset monitoring method of the position of the mobile phone 104 by the detection unit 202 will be described. In a general method in which the mobile phone 104 measures the position of its own device (the mobile phone 104), the mobile phone 104 requests a positioning from a central positioning device (not shown). The central positioning device or mobile phone 104 measures the round-trip time and reception strength of signals between the mobile phone 104 and a plurality of base stations (not shown). The position of the mobile phone 104 can be measured by performing the triangulation of the mobile phone 104 and the two base stations using the round-trip time of the measured signal or the signal strength.

In the present embodiment, it is assumed that the asset monitoring server 101 has the function of the central positioning device described above. Then, when the user transmits an application signal using the mobile phone 104, a positioning request is transmitted to the asset monitoring server 101.
Note that the present embodiment is not limited to the configuration in which the mobile phone 104 measures the position of the own device by such a method, and the position of the own device is measured by another positioning method, and the result is sent to the asset monitoring server. Any device can be used as long as 101 can be acquired.

  As another positioning method, an IC tag such as RFID (Radio frequency identification) may be attached to the mobile phone 104, and a tag reader may be provided in the range of the monitoring area a to read the tag of the mobile phone 104. Further, as another positioning method using triangulation, there is a self method in which the mobile phone 104 measures the position of its own device based on the round trip time of signals with a plurality of base stations.

The positions of the monitoring object 105 and the mobile phone 104 can also be provided by providing a wireless communication device in the monitoring object 105 or the mobile phone 104 and performing wireless communication with a plurality of wireless communication base stations installed in a predetermined section. Can be detected. As existing techniques of such a method, there are an RSSI (Received Signal Strength Indicator) method and a TDOA (Time Difference of Arriva) method.
Furthermore, a GPS (Global Positioning System) device is provided on the monitoring object 105 or the mobile phone 104 to detect the position, to detect the position using infrared rays irradiated for each specific section, the arrival of radio waves and sound waves It is conceivable to detect a position using a position positioning sensor using a time difference.

  Further, the asset monitoring server 101 according to the present embodiment is based on the position of the monitoring object 105 provided by the positioning sensor 102 and the IC tag 109 and the position of the mobile phone 104 calculated by the asset monitoring server 101. An abnormality detection unit 203 that calculates the distance between the mobile phone 104 and the mobile phone 104 is provided. The abnormality detection unit 203 determines that the monitoring object 105 and the mobile phone 104 are close to each other when the calculated distance is within a predetermined distance range. The result of the determination is sent to the permission unit 204.

  The permission unit 204 permits the movement of the monitoring target object 105 only when the abnormality detection unit 203 determines that the monitoring target object 105 and the mobile phone 104 are close to each other. In addition, a control signal is transmitted to the monitoring camera 103 via the communication unit 201. Based on the control signal, the monitoring camera 103 follows the IC tag 109 to determine a shooting range, and images a space including the monitoring target 105. The captured image is stored in the DB 108.

In the above configuration, the communication unit 201 functions as an application signal receiving unit, the detection unit 202 functions as a communication terminal device position acquisition unit, the abnormality detection unit 203 functions as a distance calculation unit and proximity determination unit, and the permission unit 204 functions as a movement availability determination unit.
The result of movement such as taking out or returning is stored in the DB 108. When the permission unit 204 determines permission to move the monitoring target object, the permission unit 204 reads the information on the monitoring target object 105 indicated by the application signal received through the communication unit 201 from the DB 108 and acquires the attribute of the monitoring target object 105. It is also possible to read the user information of the mobile phone 104 from the ID information of the mobile phone 104 that transmitted the application signal, and specify the person who applied for the application. In the present embodiment, along with the movement of the monitoring object 105, the attribute of the monitoring object 105 and the user information are stored in the DB 108.

FIG. 3 is a diagram illustrating an example of storing the movement and attributes of the monitoring target object 105 and the user information in the DB 108. FIG. 3A is an asset status table that stores the current state of the monitoring target 105. (B) is an asset movement log table in which records of taking-out and return of the monitoring object 105 are stored.
According to the asset status table shown in FIG. 3 (a), the storage location of the monitored object, the take-out status indicating whether it is taken out from the inside of the monitoring area a, the application for take-out or return has been made. You can see the time, the user name of the user who applied, and the title of the image taken at the time of application. In addition, according to the asset movement log table shown in FIG. 3B, the situation of application and return of the monitoring target, the time when the object was actually taken out and returned, the user name of the user who made the application, and the image taken at the time of application You can see the title of the image.

  Note that the present embodiment is not limited to the configuration in which the information illustrated in FIGS. 3A and 3B is stored in the DB 108. For example, the user name of a user who has a valid take-out authority for each monitoring object can be stored in the DB 108. In this way, for example, the permission unit 204 determines whether a user having a valid authority has applied for take-out. Then, it is possible to permit the monitoring object 105 to be taken out only when a person having a legitimate authority takes it out and the monitoring object 105 and the mobile phone 104 are close to each other.

  In the present embodiment, the detection unit 202 inputs information on the position of the monitoring target 105 detected by the positioning sensor 102 and the IC tag 109. The positioning sensor 102 can detect the movement of the monitoring object 105 based on a change in the signal intensity or direction of the signal transmitted from the IC tag. Further, when the IC tag transmission signal is not input to the positioning sensor 102, it can be determined that the monitoring object 105 has been moved out of the monitoring area a.

  When the detection unit 202 detects the movement of the monitoring target, the detection result is sent to the permission unit 204 via the abnormality detection unit 203. The abnormality detection unit 203 determines whether or not the monitoring object 105 and the mobile phone 104 are close to each other even when the movement of the monitoring object 105 is detected. When the monitoring object 105 is moved and movement is not permitted, that is, when the abnormality detection unit 203 determines that the monitoring object 105 and the mobile phone 104 are not close to each other, monitoring is performed via the communication unit 201. Notify the outside that the object 105 has been moved.

  If comprised in this way, it can detect that the person who does not carry the mobile telephone 104 which is an application communication terminal device carried out the monitoring target object 105 out of the monitoring area a. For example, if the communication unit 201 notifies an administrator who manages the monitoring target object 105, for example, the administrator is notified that the monitoring target object 105 is illegally taken out, thereby preventing unauthorized removal. Is also possible.

  Similarly, the detection unit 202 can determine that the monitoring target object 105 has been moved into the monitoring area a when the position information is input from a state where the position information has not been input. When the monitoring object 105 and the mobile phone 104 are not close to each other, it can be detected that a person who does not carry the mobile phone 104 brings the monitoring object 105 into the monitoring area a. If the communication unit 201 notifies the administrator of this fact, it is possible to notify the administrator that the monitoring target object 105 has been returned illegally, and to prevent unauthorized entry in advance.

In the configuration described above, the detection unit 202 functions as a movement detection unit, and the permission unit 204 and the communication unit 201 function as a notification unit.
Note that the unauthorized take-out and return notifications made by the asset monitoring server 101 of the present embodiment are not limited to such a configuration. For example, an image indicating that an abnormality has occurred may be displayed on a monitor (not shown) of the asset monitoring server 101 or may be notified by telephone or email to the administrator's mobile phone. Furthermore, it is also possible to close the door that shuts off this section that activates an alarm or warning light installed in the section of the monitoring area a that has been taken out or returned.

(Mobile phone)
FIG. 4 is a diagram for explaining the configuration of the mobile phone 104 that transmits an application signal to the asset monitoring server of the present embodiment. The mobile phone 104 displays a communication unit 401 that communicates with the asset monitoring server 101, an operation unit 403 that is operated for communication by the user, and information that is necessary for an operation using the operation unit 403 and a result of the operation. Part 402 is provided.
Note that the asset status table or the asset movement log table shown in FIG. The user can know the state of the monitoring object to be moved by looking at the displayed asset status table or asset movement log table. In addition, when moving the monitoring object, the operation unit 403 is operated to input its own name, the type of application (take-out or return), and the like. The input result is displayed on the display unit 402. In addition, the information stored in the DB 108 is updated with the input information.

(Asset monitoring method)
Next, an asset monitoring method for an object to be monitored performed by the asset monitoring server described above will be described.
(1) Taking-out FIG. 5 is a flowchart for explaining a method for applying for taking-out in the asset monitoring method for moving a monitoring object according to this embodiment. A user (applicant) who applies for taking-out of the monitoring target object acquires information on the identifier of the monitoring target object 105 to be taken-out (step S501).
As a specific method for acquiring the identifier, for example, it is conceivable to read a barcode or QR code attached to the monitoring target object 105 using a camera provided in the mobile phone 104. Further, a tag reader may be provided in the mobile phone 104, and the identifier information in the IC tag of the monitoring target 105 may be read using this tag reader. Further, the identifier information described in the monitoring target 105 may be visually recognized by the user and manually input to the mobile phone 104.

Further, the applicant inputs information on the applicant himself / herself through the operation unit 403. The input information is transmitted as a take-out application signal to the asset monitoring server 101 via the communication unit 401 together with the identifier (S502).
The asset monitoring server 101 receives a take-out application signal. The detection unit 202 detects the position of the mobile phone 104 that has transmitted the take-out application signal. Further, the position of the monitoring object 105 is detected from the position information of the monitoring object 105 detected by the positioning sensor 102 and the IC tag 109 (S503). The monitoring camera 103 captures an image of a space including the monitoring target object 105 (S504).

Next, the abnormality detection unit 203 determines whether or not the position of the mobile phone 104 is close to the monitoring target object 105. The result of the determination as to whether or not they are close to each other is sent to the permission unit 204.
The permission unit 204 permits take-out when it is determined that the mobile phone 104 and the monitoring target 105 are close to each other, and does not permit take-out when it is determined that they are not close. At this time, the permission unit 204 determines the validity of the applicant's take-out based on the contents of the application signal and the user information of the mobile phone 104 stored in the DB 108 (S505).

  Any existing technique may be used as a specific method for determining the legitimacy of taking out. For example, the applicant may be notified in advance of the ID and password, and the application for taking out using the notified ID and password may be made valid. It is also conceivable to use a method using a one-time password generator, bio-authentication using fingerprints, irises of eyes, voice, etc., and a combination of these methods.

  As a result of the determination in step S505, when the permission unit 204 permits the requested take-out (S505: allow), information on the asset status table and the asset movement log table stored in the DB 108 is determined according to the content of the take-out application signal. Update. Further, the image taken in step S503 is stored in the DB 108. Further, the mobile phone 104 is notified that the take-out is permitted and notifies the applicant (S506).

On the other hand, if the permission unit 204 determines in step S504 that the take-out is not permitted (S505: not permitted), the permission unit 204 transmits a signal indicating that the mobile phone 104 is not permitted to take out via the communication unit 201. It transmits and notifies an applicant (S507).
The communication unit 401 of the mobile phone 104 receives a signal indicating whether or not it can be taken out. The content indicated by the received signal is displayed on the display unit 402 (S508).

  FIG. 6 is a flowchart for explaining the operation of the asset monitoring system when the monitored object 105 is actually taken out after the take-out application shown in FIG. In the asset monitoring server 101, the detection unit 202 acquires the position of the monitoring target object by inputting the position of the monitoring target object 105 detected by the positioning sensor 102 and the IC tag 109. In this monitoring, the detection unit 202 determines whether or not the monitoring target object 105 has been taken out from the monitoring area a (S601). Take-out of the monitoring object 105 can be detected, for example, by a change in the reception intensity of the signal transmitted from the IC tag 109 in the positioning sensor 102 or the transmission direction of the reception signal.

When the take-out of the monitoring target 105 is detected (S601: Yes), the asset monitoring server 101 controls the monitoring camera 103 to capture an image of the monitoring target 105 (S602). Also, the information shown in FIG. 3A as the asset status table and the information shown in FIG. 3B as the asset movement log table stored in the DB 108 are updated (S603).
Further, the permission unit 204 refers to the information shown in the asset status table, and determines whether or not the application for taking out has been made properly (S604). If the application is made properly (S604: appropriate), the movement detection process ends.

  On the other hand, when the application is not properly made in step S604 (S604: inappropriate), the asset monitoring server 101 notifies the manager of the monitoring target object 105 that unauthorized take-out has been made (S605). In the case of illegal take-out, the data update in step S603 is updated with information such as the application time and the applicant being unknown, and it is recorded that the illegal take-out has been made.

(2) Return FIG. 7 is a flowchart for explaining a method for applying for return in the asset monitoring method for moving a monitoring object according to this embodiment. The applicant who applies for the return of the monitoring target object acquires information on the identifier of the monitoring target object 105 to be returned (step S701).
Further, the applicant inputs information regarding the applicant himself / herself through the operation unit 403 to the effect that he / she wishes to return the information. The input information is transmitted as a return application signal to the asset monitoring server 101 via the communication unit 401 together with the identifier (S702).

  The asset monitoring server 101 receives a return application signal. The detection unit 202 detects the position of the mobile phone 104 that has transmitted the return application signal. Further, the position of the monitoring object 105 is detected from the position information of the monitoring object 105 detected by the positioning sensor 102 and the IC tag 109 (S703). The monitoring camera 103 captures an image of a space including the monitoring target object 105 (S704).

Next, the abnormality detection unit 203 determines whether or not the position of the mobile phone 104 is within the range of the monitoring area a and is close to the monitoring target object 105. The result of the determination is sent to the permission unit 204.
When the permission unit 204 determines that the position of the mobile phone 104 is within the range of the monitoring area a and is close to the monitoring target 105, the permission unit 204 permits the return, and determines that it is not close Does not allow return. At this time, the permission unit 204 determines the validity of the return of the applicant based on the contents of the application signal and the user information of the mobile phone 104 stored in the DB 108 (S705).

  As a result of the determination in step S705, when the permission unit 204 permits the requested return (S705: permit), the information on the asset status table and the asset movement log table stored in the DB 108 is updated with the content of the return application signal. To do. In addition, the image captured in step S703 is stored in the DB. Furthermore, the applicant is notified that the return is permitted and notifies the applicant (S706).

On the other hand, when the permission unit 204 determines in step S704 that the return is not permitted (S705: not permitted), the permission unit 204 sends a signal indicating that the return is not permitted to the mobile phone 104 via the communication unit 201. The data is transmitted and notified to the applicant (S707).
The communication unit 401 of the mobile phone 104 receives a signal indicating whether return is possible. The content indicated by the received signal is displayed on the display unit 402 (S708).

  FIG. 8 is a flowchart for explaining the operation of the asset monitoring system when the monitoring target 105 is actually returned after the return application shown in FIG. The detection unit 202 of the asset monitoring server 101 determines whether or not the monitoring target object 105 has entered the monitoring area a (S801). The fact that the monitoring object 105 has entered (returned to) the monitoring area a can be detected by, for example, a change in the reception intensity of the signal transmitted from the IC tag 109 at the positioning sensor 102.

When the return of the monitoring target 105 is detected (S801: Yes), the asset monitoring server 101 controls the monitoring camera 103 to capture an image of the monitoring target 105 (S802). Also, the information shown in FIG. 3A as the asset status table and the information shown in FIG. 3B as the asset movement log table stored in the DB 108 are updated (S803).
Further, the permission unit 204 refers to the information shown in the asset status table, and determines whether or not an application for taking out the returned monitoring target object 105 has been made properly (S804). If the application has been made properly (S804: appropriate), the movement detection process ends.

  On the other hand, if the application is not properly made in step S804 (S804: inappropriate), the asset monitoring server 101 manages that the monitoring target 105 taken out illegally has been returned. (S805). In addition, when an illegal return is made, it is recorded that the monitoring object 105 taken out illegally is returned when the data is updated in step S803.

  In the flowchart shown in FIG. 8, it is determined only whether or not the application for taking out is properly made. However, the present embodiment is not limited to such a configuration, and it is also determined whether the return application shown in FIG. 7 is properly performed or whether the return and return are appropriate. May be. In this way, it is possible to detect and notify that a person without a legitimate authority has entered the monitoring area a with the monitoring object 105 properly taken out.

  In this embodiment, the user who has the mobile phone 104 that has transmitted the application signal to the asset monitoring server 101 is physically close enough to take out and return the monitoring target object 105, or at a distance that cannot be taken out and returned. Can be determined. Then, the movement of the monitoring object can be permitted only when the user who has the mobile phone 104 physically takes out the monitoring object 105 and is within a distance that can be returned. For this reason, possibility that the monitoring target object 105 will be moved by persons other than the application approved is reduced.

  The present invention described above can be applied to all configurations for monitoring articles stored in a predetermined area. Further, since it is possible to apply for the movement of the monitoring object using the mobile phone, it is possible to specify the address and name of the user (applicant) from the ID of the mobile phone and information at the time of contract. Therefore, it can be used for general purposes in various aspects of asset monitoring.
