<Monitoring system>
The monitoring system according to the embodiment of the present invention is shown in FIGS. 1 to 3. The monitoring system 100 (see FIG. 2) is a system for monitoring the behavior of an intruder (intruder) who has entered a predetermined area.

Hereinafter, the warehouse 10 in which the monitoring system 100 according to the present invention is adopted will be described with reference to FIG. 1, but the warehouse 10 is not limited to the warehouse 10 and can be used in various areas. In particular, in the monitoring system 100 according to the present invention, it is difficult to lock the entrance / exit of a refrigerator in a restaurant, a mixing room in a hospital, etc. (including the case where a door does not exist), and a person other than a predetermined person can enter and exit. It can be suitably adopted in an environment where there is a possibility of doing so and it is necessary to monitor what is being done internally.

In the present embodiment, the warehouse 10 is provided with one doorway 1, but is generally open and unlocked when it is necessary to carry in and out frequently. Therefore, in the warehouse 10, not only the staff who perform the work but also other staff and a third party can enter. Further, the warehouse 10 is provided with a shelf 2 for storing products and the like.

As shown in FIGS. 1 and 2, the monitoring system 100 includes a sensor 3 (detection device) for detecting that an intruder has entered the warehouse 10 and a camera 4 (imaging device) for capturing the state inside the warehouse 10. The RFID reader / writer 6 (acquisition device) that acquires the individual identification information of the RFID tag (individual identification information transmission member) possessed (incidental) by the intruder, the entry / exit data from the sensor 3, and the image data from the camera 4. And a control device 20 having a receiving unit 21 (see FIG. 2) for receiving individual identification information from the RFID reader / writer 6. Further, the monitoring system 100 further includes a display device 7 and a notification device 8 connected to the control device 20.

The sensor 3 is installed at a gate provided at the doorway 1. The sensor 3 detects an intruder entering the warehouse 10 from the doorway 1 and an exiting person from the warehouse 10. That is, the sensor 3 detects that the intruder has entered the warehouse 10 and that the intruder has left the warehouse 10. A motion sensor can be used as the sensor 3. When the sensor 3 detects the entry and exit of the intruder, the sensor 3 transmits the entry / exit data to the control device 20. Here, the entry / exit data includes information indicating that the intruder has passed through the entrance / exit 1. The entry / exit data does not include individual identification information of the intruder.

The camera 4 is installed so as to be able to take an image of the entire area of the warehouse 10. In the present embodiment, the camera 4 is installed in the vicinity of the doorway 1. The camera 4 constantly images the warehouse 10 to generate continuous image data shown in FIG. 5, and transmits the continuous image data to the control device 20. It is also possible to install a plurality of cameras 4 depending on the monitoring location and the like.

The RFID reader / writer 6 is installed on the ceiling of the warehouse 10. The RFID reader / writer 6 can communicate with the RFID tag in the entire area of the warehouse 10, and the individual identification information of the RFID tag is acquired by this communication. When the RFID reader / writer 6 acquires the individual identification information from the RFID tag, the RFID reader / writer 6 transmits the individual identification information to the control device 20. The location where the RFID reader / writer 6 is installed is not particularly limited, and a plurality of RFID reader / writers 6 can be installed depending on the environment.

Here, as the RFID tag, a passive type RFID tag that transmits individual identification information by transmitting a radio wave when a radio wave signal is received from an RFID reader / writer is preferably used. An RFID tag is preferably used as an individual identification information transmission member for holding individual identification information, but the present invention is not limited to this, and any element that can communicate individual identification information by radio such as a beacon can be adopted. be. For example, RFID tags are possessed by staff who need to work in the warehouse 10, employees who are officially authorized to enter the warehouse 10, and the like.

With reference to FIG. 2, as the control device 20, a computer having a receiving unit 21, a storage unit 25, and a processing unit 23 can be used.

The receiving unit 21 receives from the sensor 3 the entry / exit data that an intruder has entered the warehouse 10. The receiving unit 21 receives continuous image data from the camera 4 that captures the warehouse 10. The receiving unit 21 receives the individual identification information of the RFID tag possessed by the intruder from the RFID reader / writer 6.

The storage unit 25 stores a plurality of individual identification information registered in advance and continuous image data received by the reception unit 21. The storage unit 25 also stores personal data (name, affiliation, face photo, telephone number, e-mail address, etc.) of the person who possesses the RFID tag in association with the individual identification information. As the storage unit 25, a conventionally known storage means in a computer or the like can be used.

The processing unit 23 performs a process of storing an image taken by the camera 4 and storing the continuous image data received by the receiving unit 21 in the storage unit 25. As the processing unit 23, a conventionally known central processing unit (CPU) or the like can be used. The storage unit 25 has an image data storage area for sequentially storing continuous image data.

The processing unit 23 performs a process of detecting the number of intruders who have entered at the same time based on the continuous image data. Further, the processing unit 23 performs a process of storing the number of detected intruders in the storage unit 25. This number of intruders is stored in association with the entry / exit data. Note that "simultaneous" is not limited to the case of passing through the doorway 1 at exactly the same timing, but also includes the case of passing through the doorway 1 at the same time so that the sensor 3 cannot detect each of a plurality of intruders. Further, "simultaneous" means that the entry time (entrance time detected by the sensor 3) does not need to be the same, and even if the entry time is different, the entry time is shared by a plurality of people. including.

Further, the processing unit 23 performs a process of storing the individual identification information of the RFID tag owned by the person to be managed in the storage unit 25 in association with the personal data. The storage unit 25 has an individual identification information storage area for storing individual identification information and personal data in association with each other.

The processing unit 23 performs a process of associating the entry / exit data from the sensor 3 with the image data at the time of entry / exit. Specifically, when the receiving unit 21 receives the entry / exit data, the processing unit 23 performs a process of storing the entry / exit data in the storage unit 25 in association with the image data at the time of entry / exit. More specifically, the processing unit 23 sets a trigger for image reproduction for the continuous image data continuously stored in the storage unit 25. For example, as shown in FIG. 5, when an intruder who has acquired individual identification information enters the warehouse 10 (A and C) and when a person determined to be an unknown person enters the warehouse 10 (B). , A trigger is set for each of the continuous image data D stored in the storage unit 25. Here, the processing unit 23 performs the above-mentioned processing of associating the entry / exit data at a predetermined timing. It is conceivable to set this predetermined timing according to the application and necessity such as the timing at which the entry / exit data is acquired and the timing at which the predetermined operation is performed.

The processing unit 23 performs a process of extracting the corresponding personal data from the storage unit 25 when the receiving unit 21 receives the individual identification information from the RFID reader / writer 6.

The processing unit 23 performs a process of detecting the number of individual identification information simultaneously acquired from the RFID reader / writer 6. Further, the processing unit 23 performs a process of storing the number of detected individual identification information in the storage unit 25. The number of individual identification information is stored in association with the entry / exit data.

Further, the processing unit 23 performs a process of determining whether or not the number of intruders detected as described above and the number of individual identification information acquired from the RFID reader / writer 6 match. The processing unit 23 stores the determination result in the storage unit 25 in association with the entry / exit data.

In addition, the processing unit 23 performs processing for associating the individual identification information from the RFID reader / writer 6 with the entry / exit data and the continuous image data. Specifically, when the receiving unit 21 receives the individual identification information, the processing unit 23 performs a process of storing the individual identification information in the storage unit 25 in association with the entry / exit data and the continuous image data. This process by the processing unit 23 is performed when the time when the individual identification information is received and the time when the entry / exit data is received are within a predetermined time difference. Here, the predetermined time difference can be appropriately set depending on the place where it is installed or the like. In addition, the processing unit 23 performs the processing of associating the individual identification information as described above at a predetermined timing. It is conceivable to set this predetermined timing according to the application and necessity such as the timing when the individual identification information is received and the timing when the predetermined operation is performed.

On the other hand, the processing unit 23 does not receive the individual identification information before the lapse of a predetermined time after the receiving unit 21 receives the entry / exit data, or the number of detected intruders and the individual identification information received from the RFID reader / writer 6. If the numbers do not match, the individual identification information of the intruder is associated with the entry / exit data and the continuous image data as an unknown person and stored in the storage unit 25. When the number of detected intruders and the number of individual identification information received from the RFID reader / writer 6 do not match, the processing unit 23 also associates the individual identification information received from the RFID reader / writer 6 with the entry / exit data and the continuous image data. And store it in the storage unit 25. Specifically, if there are three intruders but only two individual identification information can be obtained, it is recognized as an unknown person and the unknown person information is stored in association with the entry / exit data and the continuous image data. At the same time, the individual identification information for two people is also stored in association with the entry / exit data and the continuous image data. The storage unit 25 has an entry / exit management data storage area for sequentially storing entry / exit management data including entry / exit data, corresponding entry / exit time data, and corresponding personal data or unknown person information.

The processing unit 23 performs a process of displaying the reproduction start key 72 on the display device 7 together with the individual identification information stored in the storage unit 25 and the information related to the individual identification information such as the entry / exit time of the intruder. As shown in FIG. 3, the reproduction start keys 72 are displayed side by side in chronological order on the screen, and the reproduction start keys 72 are different for each column. The order of the reproduction start key 72 can be changed (sorted) by a predetermined operation, and for example, only an image with a specific name can be displayed. As the display device 7, a conventionally known monitor can be used.

Here, as shown in FIG. 3, the display screen 71 displayed on the display device 7 has a current image display unit 73 that displays an image of the current warehouse 10 and a selection image display unit 74 that displays the selected image. And have. Further, on the display screen 71, the information of the person who entered the warehouse 10 and the time of entry are displayed as the information related to the reproduction start key 72 and the individual identification information. Then, when the predetermined reproduction start key 72 is selected, the continuous image from the timing when the trigger is set on the display device 7 based on the reproduction start key 72 is reproduced. Here, as shown in FIG. 3, the reproduction start key 72 has one key in which columns such as information of the intruder arranged in chronological order (columns 1, 2 and 3, respectively) are one key. It should be noted that this selection is made by the operation of an operation unit (for example, a mouse) (for example, a mouse) (not shown) of the observer who performs monitoring. The display device 7 and the control device 20 are installed at a location different from the warehouse such as a monitoring room.

When the observer performs a predetermined operation such as selection of a sort button (not shown) by the operation unit, the processing unit 23 identifies the data corresponding to the image reproduction key 22 stored in the storage unit 25 to a specific individual. Performs sorting by information or unknown person information. Therefore, it is possible to display only the image reproduction key 22 related to the unknown person information on the display device 7, or to display only the image reproduction key 22 related to the specific person.

When the entry / exit data is received, the processing unit 23 performs a process of notifying the notification device 8. For example, if the processing unit 23 receives the entry / exit data and does not receive the individual identification information before the predetermined time elapses after receiving the entry / exit data, the processing unit 23 performs a process of causing the notification device 8 to notify an alarm. As the notification device 8, for example, a lighting lamp is used. Further, when the processing unit 23 receives the entry / exit data and receives the individual identification information before the predetermined time elapses after receiving the entry / exit data, the processing unit 23 performs a process of normally notifying the notification device 8. Specifically, the notification device 8 may have a red lamp for alarm notification and a blue lamp for normal notification. Although the notification device 8 is installed in the warehouse 10 in the illustrated example, it can be installed in a room for monitoring, for example.

Further, the processing unit 23 determines whether to enter or leave the room based on the timing of the reception of the entry / exit data and the reception of the individual identification information in the reception unit 21, and stores the entry / exit data in the storage unit 25. Specifically, for example, in a monitoring system in which the reception range of the RFID reader / writer extends to the outside of the warehouse 10, the processing unit 23 determines that the room is entered when the entry / exit data is received after the individual identification information is received. However, if the individual identification information is no longer received after the entry / exit data is received, it can be determined that the room has been left. It is also possible to install two sensors side by side in the approach direction at the entrance and determine the entry / exit according to the timing of detection of the two sensors.

<Operation>
Next, the operation (monitoring method) of the monitoring system 100 will be described with reference to FIG. The image pickup apparatus 4 constantly continuously images the entire warehouse 10 and generates continuous image data. The continuous image data generated by the image pickup apparatus 4 is stored in the storage unit 25 via the processing unit 23.

At the entrance / exit 1 of the warehouse 10, the sensor 3 detects an intruder (S100), and in a state where the intruder does not pass through the entrance / exit 1, the sensor 3 waits until the intruder passes through (No in S100). When an intruder passes through the entrance / exit 1 (Yes in S100), the sensor 3 detects the intruder and transmits the entry / exit data to the control device 20. When the entry / exit data is transmitted from the sensor 3 to the control device 20, a trigger corresponding to the time of receipt of the entry / exit data is set in the continuous image data stored in the storage unit 25 (S200).

When the entry / exit data is transmitted from the sensor 3 to the control device 20, a trigger corresponding to the time of receipt of the entry / exit data is set in the continuous image data stored in the storage unit 25 (S200). Specifically, as shown in FIG. 5, the processing unit 23 sets a trigger (see A, B, and C) for the continuous image data D at a predetermined time in the storage unit 25.

When an intruder passes through the doorway 1 and enters the warehouse 10, it is determined whether or not the RFID reader / writer 6 communicates with the RFID tag in the warehouse 10 (S300). At this time, it is also determined whether the number of intruders and the number of RFID tags that have communicated match. If the intruder does not have the RFID tag of the individual identification information registered in the storage unit 25 in advance, or if the number of intruders and the number of RFID tags that have communicated do not match (No of S300). After the control device 20 receives the entry / exit data, the RFID reader / writer 6 cannot receive the individual identification information even after a predetermined time has elapsed, and it is determined that the intruder is an unknown person (S400). When it is determined that the intruder is an unknown person, the notification device 8 lights a red lamp and an alarm notification is made (S410).

When the number of intruders and the number of RFID tags that have communicated match, and the intruder possesses the RFID tag of the individual identification information registered in the storage unit 25 in advance (Yes in S300), After the control device 20 receives the entry / exit data, the RFID reader / writer communicates with the RFID tag to receive the individual identification information. Upon receiving this individual identification information, the name of the intruder is determined from the individual identification information (S500). When the individual identification information is received, the notification device 8 turns on the blue lamp, and normal notification is performed (S510).

After the normal notification or the alarm notification is made, it is determined whether or not a predetermined time has elapsed (S600). When the predetermined time has elapsed (Yes in S600), the notification device 8 is turned off (S700). On the other hand, if the predetermined time has not elapsed (No in S600), the process waits until the predetermined time elapses.

<Advantage>
In the monitoring system 100, an intruder is detected by using the RFID reader / writer 6 and the sensor 3. Therefore, it can be detected that not only a legitimate intruder who has an RFID tag but also an unknown person who does not have an RFID tag has invaded the warehouse.

In this monitoring system 100, the individual identification information of the intruder or the information that the intruder is unknown is stored in the storage unit 25 in association with the entry / exit time and the like, and is displayed on the display device 8 in association with the reproduction start key 72. There is. Therefore, it is possible to easily confirm the information of the intruder such as the name and the time when the intruder entered. At this time, if you want to confirm what you did when the intruder entered, you can check the continuous image in the warehouse 10 from the time when the intruder entered by selecting the playback start key 72. can. Therefore, when an irregular state such as loss of an article occurs in the warehouse 10, continuous image data from a specific location can be confirmed while selecting from a large number of image data, and it is easy to manage the approaching body. And it can be done reliably.

Further, the display device displays the fact that the person is unknown or the name of the intruder, and by selecting the playback start key 72 and visually recognizing the image of the unknown person or a specific individual, all the continuous images can be displayed. It is possible to easily confirm the part where an unknown person or a specific individual is reflected without continuously visually recognizing. Therefore, in this monitoring system 100, it is possible to easily confirm who has entered and what kind of action has been taken.

Therefore, in the monitoring system 100, it is possible to easily and surely monitor and manage the actions of the intruder even in a warehouse or the like where it is difficult to strictly restrict the entry and exit of the entrance / exit.

Further, since the notification device 8 determines whether or not the person who has entered the warehouse 10 is a registered person in advance and notifies the user, he / she does not possess a third party who accidentally entered the warehouse 10, for example, an RFID tag. You can make the staff notice the mistake.

In this monitoring system 100, the camera 4 constantly images the inside of the warehouse 10 to generate one continuous image data, and when an intruder is detected, the continuous image data is used when the entry / exit data is received. A trigger is set and the playback start key 72 is set. Therefore, even if the number of intruders is large and a large number of playback start keys 72 are set, the capacity of the image data does not increase, the capacity of the storage unit 25 can be easily set, and it is necessary to use a storage unit having a large storage capacity. do not have.

It is configured to detect the entry of an approaching body, acquire entry / exit data, acquire individual identification information from an individual identification information acquisition device, and determine whether or not the approaching body possesses an individual identification information transmission member. Even if there is, if it does not have a configuration for detecting the number of approaching bodies, if an approaching body having an individual identification information transmitting member and an approaching body not possessing an individual identification information transmitting member enter at the same time, It may not be possible to detect the entry of an approaching body that does not possess individual identification information.

In this case, it may not be possible to recognize that the approaching body having no individual identification information transmitting member has entered the predetermined area, and it may not be possible to sufficiently manage such the approaching body.

However, in this monitoring system 100, even when a plurality of intruders including an intruder who has an RFID tag and an intruder who does not have an RFID tag try to pass through the doorway 1 at the same time, the camera 4 takes an image. Based on the number information of the intruders detected from the image data and the individual identification information acquired by the RFID reader / writer 6, it is possible to detect that an intruder who does not have the RFID tag has passed. Therefore, even if an intruder who does not have an RFID tag tries to enter by being confused by an intruder who has an RFID tag, an intruder who does not have an RFID tag enters and manages the behavior in the warehouse 10. , Can be monitored.

[Other embodiments]
Although the above-described embodiment has the above-mentioned advantages from the above-mentioned configuration, the present invention is not limited to the above-mentioned configuration of the above-described embodiment, and the design can be appropriately changed within the scope of the present invention.

That is, in the above embodiment, when the acquisition device acquires the individual identification information, the description is made on the premise that the individual identification information is stored in the storage unit, but the acquired individual identification information is stored in the storage unit. If not, it can be treated as an unknown person.

Further, in the above embodiment, a sensor has been described as an example of a detection device for detecting an approaching body, but the present invention is not limited to this, and the detection device is generated by an image pickup device. It is also possible to detect an intruder based on the image data. Specifically, the processing unit determines whether or not there is an operation (entrance operation of the approaching body) in the image data captured by the image pickup device from the image data before and after, and if there is an operation, it is determined that the approaching body has entered.
