The arithmetic processing unit executes the executed program.

  The inspection device 12 is a device that continuously inspects the cargo J transported by the conveyor 13 under the control of the controller 11 by, for example, irradiating X-rays. In FIG. 1, the entrance of the inspection device 12 into which the package J is carried is shown in the downward direction, and the exit from which the package J is carried out is shown in the upward direction.

  The conveyor 13 is a device that conveys the cargo J placed by the customer P2 for the inspection device 12 to inspect. The conveyor 13 carries the parcel J placed by the customer P2 into the entrance of the inspection device 12. Then, the conveyor 13 further conveys the parcel J carried in to the entrance, passes the position where the inspection is performed by the inspection device 12, and carries it out from the exit of the inspection device 12. The conveyor 13 is, for example, a belt conveyor. In FIG. 1, the conveyor 13 conveys the cargo J from the outside L on the lower side to the inside H on the upper side.

  In addition, the conveyor 13 may be configured by, for example, an integral belt conveyor. Further, the conveyor 13 has a belt conveyor or the like which is divided into an upstream side in the conveyance direction from the entrance of the inspection device 12, an inside of the inspection device 12, and a downstream side in the conveyance direction from the exit of the inspection device 12. It may be composed of.

  In the example shown in FIG. 1, a cover C1 is provided so as to cover a region extending from the entrance of the inspection device 12 toward the upstream side of the conveyor 13 in the transport direction. Further, in the example shown in FIG. 1, a cover C2 is provided so as to cover a region extending from the outlet of the inspection device 12 toward the downstream of the conveyor 13 in the transport direction. Both the cover C1 and the cover C2 are made of transparent members, and the inside is visible from the outside.

  The camera 14 is an image pickup device that picks up an image of an object, and includes, for example, an optical system including a lens, a reflecting mirror, a prism, and the like, and an image pickup device such as a CMOS (Complementary Metal Oxide Semiconductor) or a CCD (Charge Coupled Device). It is a digital still camera.

  The camera 14 images the entrance of the inspection apparatus 12 into which the luggage J is carried, and supplies the controller 11 with image data indicating a taken image (hereinafter, referred to as an entrance image S1 (see FIG. 2 and the like)).

  The inspection device 12 also inspects the inside of the package J by seeing through the inside of the package J, and the image data indicating an image showing the inspection result of the package J (hereinafter, referred to as an inspection image S2 (see FIG. 3)) as a controller. Supply to 11.

  The display device 15 has a display screen such as a liquid crystal display, and displays an image under the control of the controller 11. On the display screen of the display device 15, a transparent touch panel that receives an operation by sensing contact / approach of an indicator such as a finger may be arranged in an overlapping manner.

  When the controller 11 receives the image data indicating the entrance image S1 described above from the camera 14, the controller 11 sends a control signal for causing the display device 15 to display the entrance image S1 based on the image data. When the display device 15 receives the control signal from the controller 11, the display device 15 displays the entrance image S1 described above on the display screen according to the control signal.

  When the controller 11 receives the image data indicating the inspection image S2 from the inspection device 12, the controller 11 sends a control signal for displaying the inspection image S2 on the display device 15 based on the image data. . When receiving the control signal from the controller 11, the display device 15 displays the above-described inspection image S2 on the display screen in response to the control signal.

  The display screen of the display device 15 is directed to the monitor P1 on the exit side of the inspection device 12, and the entrance image S1 and the inspection image S2 displayed on the display screen are visually recognized by the monitor P1.

<Operation of inspection system>
An example of the operation of the inspection system will be described below. The inspector P1 shown in FIG. 1 needs to respond to the customer P2 who enters the hall H from the outside L according to the inspection result of the package J, such as holding or prompting reinspection, and therefore the inspection device. Standing at the 12 exit side. Therefore, the observer P1 can see the exit of the inspection device 12 through the transparent cover C2, but cannot see it because the entrance is a shadow (blind spot) of the inspection device 12.

  The camera 14 images the entrance of the inspection device 12 through the transparent cover C1 and supplies the controller 11 with image data indicating the taken entrance image S1. The controller 11 causes the display device 15 to display the entrance image S1 indicated by the supplied image data. The display device 15 displays the entrance image S1 on the display screen, and the surveillance staff member P1 confirms this. Thereby, the monitoring staff P1 confirms the inspection result of the luggage J by the inspection device 12, and at the same time, monitors the entrance of the inspection device 12 by the entrance image S1 captured by the camera 14.

  FIG. 2 is a diagram showing an example of the entrance image S1 displayed on the display device 15 when the inspection device 12 does not detect an abnormality. The controller 11 displays the entrance image S1 supplied from the camera 14 on the display device 15 as shown in FIG. Display it.

  The entrance image S1 is an image captured by the camera 14 showing how the parcel J is transported inside the cover C1. In the example shown in FIG. 2, the display device 15 displays the entrance image S1 in the entire area A0 of the display screen. The monitoring person P1 monitors the entrance image S1 and confirms whether or not there is an abnormality, such as whether the luggage J is jammed or the user is erroneously putting his / her hand or the like.

  On the other hand, when the inspection device 12 detects an abnormality, the controller 11 receives the image data indicating the above-described inspection image S2 as the inspection result. Then, the controller 11 causes the display device 15 to display the inspection image S2 indicated by the image data. That is, the controller 11 switches the displayed entrance image S1 to the inspection image S2 and causes the display device 15 to display the inspection image S2.

  FIG. 3 is a diagram showing an example of the inspection image S2 displayed on the display device 15 when the inspection device 12 detects an abnormality. The inspection device 12 analyzes the transmission image obtained by irradiating the package J with X-rays and recognizes the shape and type of the content of the package J. When the inspection device 12 recognizes the shape of a dangerous substance (a knife in the example of FIG. 3) in the contents of the luggage J, the inspection device 12 determines that “an abnormality has been detected”, and writes a warning display in the transparent image of the luggage J, for example. The inspection image S2 is generated and supplied to the controller 11.

  Upon receiving the inspection image S2 from the inspection device 12, the controller 11 causes the display device 15 to display the inspection image S2. That is, when the inspection device 12 inspects the inside of the luggage J and detects an abnormality (that is, when an abnormality is detected), the controller 11 displays an image to be displayed on the display device 15 as shown in FIG. To the inspection image S2.

  As described above, in the inspection system 1, the camera 14 captures an image of the inside of the cover C1, and the captured entrance image S1 is displayed on the display device 15 in real time. Thereby, the surveillance staff member can confirm whether the luggage J transported by the conveyor 13 is jammed at the entrance or the hand of the customer P2 is caught in the entrance. Further, when the inspection device 12 detects a dangerous substance, the display of the display device 15 is switched, so that the surveillance staff member P1 only needs to pay attention to the display screen of the display device 15.

  Further, according to this inspection system 1, if the monitor P1 is arranged only on the exit side of the inspection device 12, another monitor who visually monitors the entrance side of the inspection device 12 is unnecessary.

  The configurations, shapes, sizes, and positional relationships described in the above embodiments are only roughly shown to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, but can be modified in various forms without departing from the scope of the technical idea shown in the claims.

<Modification>
The above is the description of the embodiment, but the contents of this embodiment can be modified as follows. Further, the following modified examples may be combined.

<Modification 1>
In the above-described embodiment, the inspection device 12 supplies the inspection image S2 to the controller 11 when the abnormality is detected, but may supply the inspection image S2 to the controller 11 when the abnormality is not detected. The inspection apparatus 12 may supply the inspection image S2 to the controller 11 each time an inspection result is obtained, regardless of whether the inspection result is abnormal or normal.

  In this case, the controller 11 preferentially displays the inspection image S2 on the display device 15 for a certain time at the timing when the inspection device 12 supplies the inspection image S2, and otherwise displays the entrance image S1 on the display device 15. . That is, the controller 11 switches the entrance image S1 to the inspection image S2 and causes the display device 15 to display the inspection image S2 at the timing when the inspection result is obtained.

  FIG. 4 is a diagram showing an example of the inspection image S2 displayed at the timing when the inspection result comes out. When the inspection device 12 outputs the inspection result of the package J and displays the inspection image S2 while the entrance image S1 shown in FIG. 2 is displayed on the display device 15, the controller 11 supplies the inspection image S2 for a certain period of time such as several seconds. , The inspection image S2 shown in FIG. 4 is displayed on the display device 15. Then, when this fixed time has elapsed, the controller 11 displays the original entrance image S1 on the display device 15. Thereby, the monitoring staff P1 views the inspection image S2 for a certain period of time at the timing when the inspection result appears, regardless of the inspection content. As a result, for example, even if there is a failure in the inspection by the inspection device 12, the inspection image S2 is displayed at the timing when the inspection result comes out, so that the supervisor P1 can easily detect the abnormality.

<Modification 2>
In the above-described embodiment, the controller 11 switches and displays the entrance image S1 and the inspection image S2 on the display device 15, but they may be simultaneously displayed. FIG. 5 is a diagram showing an example of the entrance image S1 and the inspection image S2 which are simultaneously displayed by the display device 15. As shown in FIG. 5, the display screen of the display device 15 is divided into left and right halves, and the entrance image S1 is displayed in the left area A1 and the inspection image S2 is displayed in the right area A2. Thereby, the monitor P1 simultaneously confirms the entrance image S1 and the inspection image S2.

<Modification 3>
When the display device 15 displays the entrance image S1 and the inspection image S2 on the display screen at the same time, the areas such as the area, the position, the shape, the thickness and color of the boundary line, and the presence or absence of blinking are different. May be.

  For example, the display device 15 divides the display screen into a rectangular area whose width and height are both half or less of the entire display screen and an area other than this area. Then, the display device 15 may simultaneously display the entrance image S1 and the inspection image S2 in these two regions having different areas. In this way, when the areas of the regions obtained by dividing the display screen are different, the amount of information of the image that the observer P1 can see in detail varies from region to region, so images that need to be monitored more carefully, It is desirable to display in a large area.

  The display device 15 simultaneously displays, for example, the inspection image S2 in a region having a relatively small area and the entrance image S1 in a region having a relatively large area.

  Thereby, the monitor P1 simultaneously confirms the entrance image S1 and the inspection image S2. The monitoring staff P1 will carefully monitor the entrance image S1 displayed in the area occupying a larger area than the area in which the inspection image S2 is displayed, more carefully than the inspection image S2.

<Modification 4>
When the display device 15 simultaneously displays the entrance image S1 and the inspection image S2 on the display screen, the image to be displayed in each of the two divided areas is switched depending on whether or not an abnormality is detected by the inspection device 12. May be.

  For example, when the inspection device 12 detects an abnormality and notifies the controller 11 to that effect, the controller 11 instructs the display device 15 to switch the display of the two divided areas. As a result, the display device 15 simultaneously displays the entrance image S1 in a relatively small area and the inspection image S2 in a relatively large area.

  Thereby, the monitor P1 simultaneously confirms the entrance image S1 and the inspection image S2. After the inspection device 12 detects an abnormality, the monitoring staff P1 carefully monitors the inspection image S2 displayed in the area occupying a larger area than the area in which the entrance image S1 is displayed, more carefully than the entrance image S1. Will be done.

<Modification 5>
In the above-described embodiment, the controller 11 switches the image displayed on the display device 15 when the abnormality is detected from the entrance image S1 to the inspection image S2. That is, in the above-described embodiment, the controller 11 switches the display of the display device 15 based on the inspection result of the package J inspected by the inspection device 12, but the loading of the package J placed on the conveyor 13 by the customer P2. The display of the display device 15 may be switched based on the placement state.

  FIG. 6 is a diagram for explaining a loaded state of the luggage J. The luggage J shown in FIG. 6 is luggage such as a tote bag. The height of the luggage J shown in FIG. 6 is larger than the height and width of the cover C1. The cover C1 shown in FIG. 6 covers the transport path of the conveyor 13 on the inlet side of the inspection device 12. The conveyor 13 conveys the parcel J placed on the conveyance path in the direction of the arrow shown in FIG. 6, passes through the conveyance space S surrounded by the cover C1 and the conveyor 13, and is carried into the entrance of the inspection device 12. To do.

  Therefore, the luggage J shown in FIG. 6 is likely to come into contact and jam in the height direction and the width direction of the cover C1 unless it is placed so that the longitudinal direction is along the transport direction.

  FIG. 7 is a diagram showing an example of the entrance image S1 when the placement state of the luggage J is abnormal. Since the load J rolls over in the width direction of the conveyor 13 before entering the transfer space S, as shown in FIG. 7, it cannot be transferred while being in contact with the upstream end of the cover C1.

  The controller 11 analyzes the entrance image S1 supplied from the camera 14. The controller 11 acquires, for example, the entrance image S1 at relatively short constant intervals such as one second, detects the contour of the object reflected in each entrance image S1, and specifies the change over time of the contour. The state of the luggage J is analyzed by.

  When the entrance image S1 shown in FIG. 7 is analyzed, the controller 11 detects that the luggage J has not moved at the upstream end of the cover C1 for a predetermined period. As a result, the controller 11 determines that the loading state of the luggage J is abnormal, and instructs the display device 15 to display the entrance image S1. That is, the inspection system 1 switches the display of the display device 15 based on the placement state of the luggage J placed on the conveyor 13 by the customer P2. As a result, the monitor P1 recognizes that there is an abnormality in the loading state of the luggage J.

<Modification 6>
Each of the divided areas of the display screen may have different attributes such as an area, a position, a shape, a thickness and a color of a boundary line, and the presence or absence of blinking. Further, these attributes may change according to the inspection result of the luggage J and the degree of abnormality of the loading state of the luggage J.

  For example, the controller 11 or the inspection device 12 classifies the inspection result and the mounting state described above into three stages such as “danger”, “caution”, and “necessary monitoring” according to the degree of abnormality. Here, “danger” is a stage where the degree of abnormality is higher than “caution”, and “caution” is a stage where the degree of abnormality is higher than “necessary monitoring”. The controller 11 may adjust the attributes of each area in accordance with these steps so that the area of the important area is increased.

  For example, if both the inspection result and the degree of the mounting state abnormality described above are classified into “monitoring required”, the controller 11 allocates the entrance image S1 and the inspection image S2 to the display device 15 with the allocation shown in FIG. Is displayed. In this case, the observer P1 looks at the entrance image S1 and the inspection image S2 displayed in the areas having the same area, and therefore pays equal attention to both of them.

  On the other hand, when the degree of abnormality of the inspection result is classified into “danger” and the degree of abnormality of the mounting state is classified into “need to be monitored”, the controller 11 displays on the display device 15 according to the degree of each abnormality. The display screen into different areas. Then, the controller 11 changes the allocation and displays the entrance image S1 and the inspection image S2 in each of the divided areas.

  That is, the inspection image S2 showing the inspection result that is judged to be more dangerous (the degree of abnormality is high) is displayed in a region having a larger area. On the other hand, the entrance image S1 indicating the placement state, which is determined to be not dangerous (the degree of abnormality is low) compared to the inspection result, is displayed in another area having a smaller area than the area described above. In this case, the monitor P1 pays more attention to the inspection image S2 than to the entrance image S1.

<Modification 7>
In the above-described embodiment, the cover C1 covers the area from the inlet of the inspection device 12 toward the upstream of the conveyor 13 in the transport direction, and the cover C2 covers the area from the outlet of the inspection device 12 toward the downstream of the conveyor 13 in the transport direction. Was provided. The inspection system 1 may be provided with only one of these covers. That is, the inspection system 1 may be provided with a cover on at least one of the entrance of the inspection device 12 and the exit of the inspection device 12 from which the cargo J is carried out. In this case, the camera 14 may image the inside of these covers, and the controller 11 may display the image captured by the camera 14 on the display device 15.

<Modification 8>
In the above-described embodiment, both the cover C1 and the cover C2 are made of transparent members, and all of the inside is visible from the outside, but at least a part of the inside is visible from the outside. Good.

  FIG. 8 is a diagram showing an example of the cover C1 in which a part of the inside can be visually recognized from the outside. The cover C1 shown in FIG. 8 is composed of a plurality of wires C10 assembled in a grid pattern. Since there is no object in the gap area A between the wires C10, the inside of the cover C1 is visible. That is, in the cover C1 shown in FIG. 8, a part of the gap region A from the outside to the inside is visible.

<Modification 9>
Further, in the cover C1 or the cover C2, the region on the inner wall surface thereof which the luggage J contacts may be covered with a member having less friction than these. FIG. 9 is a diagram showing an example in which a region on the inner wall surface of the cover C1 where the luggage J contacts is covered with the film F. The film F shown in FIG. 9 is a member formed of a transparent material having a friction coefficient smaller than that of the material of the cover C1, and covers the region where the luggage J contacts with the inner wall surface of the cover C1.

  For example, when the cover C1 is made of a material such as glass, acrylic resin, or polycarbonate resin, when the luggage J is made of a leather or vinyl material, it is difficult to slip and is easily clogged when it comes into direct contact.

  Since the film F is made of a transparent material having a smaller friction coefficient than the material of the cover C1, the load J and the cover C1 do not come into direct contact with each other, and the load J slips even if the load contacts the film F. Therefore, as shown in FIG. 9, it is less likely to be clogged as compared with the case where the cover C1 is not coated with the film F.

<Modification 10>
The program executed by the controller 11 of the inspection system 1 is recorded on a computer-readable recording medium such as a magnetic recording medium such as a magnetic tape or a magnetic disk, an optical recording medium such as an optical disk, a magneto-optical recording medium, or a semiconductor memory. It can be provided in a stored state. It is also possible to download this program via a communication line such as the Internet. Various devices other than the CPU may be applied as the control means exemplified by the controller 11 described above, and for example, a dedicated processor or the like is used.
