Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE An embodiment of the present invention relates to an entrance management system and an entrance management control device. [Background technology]

[0002] Visitors to public transportation, event venues, government offices, etc. undergo baggage inspection. To improve inspection throughput, a smart lane inspection system is known that allows multiple people to prepare for baggage inspection at the same time. A space is provided in one inspection lane for multiple people to prepare for baggage inspection, and those who have completed their preparations for inspection sequentially place their luggage on the inspection lane and undergo baggage inspection. Visitors who pass the baggage inspection are allowed to enter, and visitors who fail are subjected to additional inspection as appropriate. This configuration reduces the number of staff required per visitor to the inspection system, leading to labor savings.

[0003] Here, if visitors are forced to carry out baggage inspections themselves, there is a risk that the inspection will not be carried out properly and visitors will enter illegally. As a method for preventing illegal entry by visitors, a crime prevention support system that supports theft prevention in retail stores such as bookstores is known (see Patent Document 1, for example). In Patent Document 1, a system determines whether a person photographed by a camera is carrying an object that can be stolen, and notifies a security guard of a person carrying an object that can be stolen, thereby preventing the theft of goods.

[0009] Hereinafter, the embodiments will be described with reference to the drawings. In the following description, the X-axis, Y-axis, and Z-axis represent axes perpendicular to each other, and the +X-axis direction, +Y-axis direction, and +Z-axis direction represent positive directions parallel to the X-axis, Y-axis, and Z-axis, respectively. The -X-axis direction, -Y-axis direction, and -Z-axis direction represent negative directions parallel to the X-axis, Y-axis, and Z-axis, respectively. When simply referring to the X-axis direction, the Y-axis direction, and the Z-axis direction, they include both the + and - directions along the X-axis, Y-axis, and Z-axis, respectively.

[0010] As mentioned above, if an entrance management system is constructed that determines whether or not an entrance visitor needs to be inspected based on the presence or absence of baggage, baggage inspection will be mandatory for even small items such as mobile phones, wallets, food and drink, writing implements, etc., and there is a risk that inspection throughput will decrease due to an increase in the number of visitors. In addition, there is a risk that dangerous items or prohibited items will be brought in by receiving uninspected baggage or dangerous items from a third party after inspection, or receiving an ID from a third party.

[0011] For example, in the case of explosives, the degree of danger is roughly proportional to the size of the explosive. In addition, in the case of smuggling of prohibited items such as drugs, precious metals, jewelry, etc., the amount of damage is roughly proportional to the size of the smuggled items brought in. Therefore, depending on the object of inspection and the purpose of the inspection, inspection of baggage smaller than a certain size may not be required. If an entrance management system is constructed that determines the necessary inspection depending on the size of the baggage carried by an entrance visitor, for example, inspection throughput can be improved by making baggage inspection mandatory for entrance visitors carrying large baggage and allowing entrance visitors carrying only small baggage to be admitted without inspection.

[0012] When there are multiple baggage inspection devices with different maximum sizes that can be inspected, the inspection efficiency can be improved by determining which one to use based on the size of the baggage and displaying this to the user.In addition, the inspection efficiency can also be improved by determining and displaying an appropriate inspection process based on the size of the baggage, such as determining that baggage exceeds the size that can be inspected by the baggage inspection device and informing the bearer that they should undergo visual inspection.

[0013] Furthermore, if the inspection system is configured to require, for example, a high-throughput walk-through type body inspection even for visitors carrying only small baggage, it will be possible to prevent visitor belongings from being overlooked without reducing the inspection throughput. Also, by appropriately acquiring the number of pieces of baggage of a predetermined size or larger carried by a visitor after baggage inspection, it will be possible to detect the receipt of uninspected baggage or dangerous objects from a third party after baggage inspection.

[0014] In consideration of the above, this embodiment presents an entrance management system that can achieve both prevention of unauthorized entry by visitors and improvement of inspection throughput.

[0015] (First embodiment) First, the first embodiment will be described.

[0016] FIG. 1 is a diagram showing a schematic configuration of an entrance management system 10 according to the first embodiment.

[0017] The entrance management system 10 includes, for example, a baggage determination device 11, an entrance management device 12, and a storage device 1001.

[0018] The storage device 1001 may be, for example, a main storage device such as a semiconductor memory, or an auxiliary storage device such as a hard disk drive (HDD) or a solid state drive (SDD). It may also be a cloud storage accessible via the Internet. The storage device may be installed inside an inspection system 300 using the entrance management system 10, which will be described later with reference to FIG. 2, or may be a server or cloud storage installed outside the inspection system 300. The storage device 1001 has a function of storing information input from the outside via a wired or wireless connection, and outputting the stored information to the outside. It may also have a function of constructing a database in which the stored information is linked to each other and organized. In the first embodiment, the storage device 1001 is a server installed outside the inspection system 300.

[0019] The baggage determination device 11 determines whether or not baggage contains a specified object determined by the manufacturer, administrator, or the like. The specified object may be, for example, an explosive, a drug, a firearm, a knife, a precious metal, or the like. The specified object is not limited to a solid, but may also be a liquid or a gas. In addition, the specified object may include a container capable of containing the specified object.

[0020] The baggage determination device 11 includes, for example, a processing unit 1101, a first ID recognition unit 1102, a first determination unit 1103, and a display device 1104.

[0021] The processing unit 1101 is, for example, an electronic circuit such as an IC (Integrated circuit). Alternatively, the processing unit 1101 is, for example, an integrated circuit such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (Field-programmable gate array), or a microcontroller. Alternatively, the processing unit 1101 may be a computer such as a server having a built-in CPU or GPU. The processing unit 1101 processes information input from, for example, the first ID recognition unit 1102, the first determination unit 1103, or the display device 1104, and outputs the processed information to the storage device 1001, the first determination unit 1103, or the display device 1104.

[0022] The processing unit 1101 may be hardware built into the first determination unit 1103, or may be hardware installed outside the first determination unit 1103 and connected via wire or wirelessly to the first ID recognition unit 1102, the first determination unit 1103, the display device 1104, and the storage device 1001. For example, the processing unit 1101 may be a server capable of inputting and outputting processing information via the Internet.

[0023] One processing unit 1101 may be configured to be able to input information from a plurality of first ID recognition units 1102, a plurality of first determination units 1103, and a plurality of display devices 1104. Also, one processing unit 1101 may be configured to be able to output information to a plurality of first determination units 1103 and a plurality of display devices 1104.

[0024] The first ID recognition unit 1102 includes a sensor for acquiring ID information held by the user of the baggage determination device 11, for example. The first ID recognition unit 1102 may include a magnetic sensor for recognizing a magnetic ticket, or an optical sensor for recognizing an IC ticket, a one-dimensional barcode, a two-dimensional barcode, or the like. Alternatively, the first ID recognition unit 1102 may include a sensor for recognizing biometric information. For example, an optical sensor included in the first ID recognition unit 1102 may acquire an image of the face, fingerprint, retina, or the like of the user of the baggage determination device 11, and the processing unit 1101 may perform biometric authentication by collating the acquired biometric information with biometric information previously stored in the storage device 1001. The biometric information acquired by the first ID recognition unit 1102 may be used as the first ID. The first ID recognition unit 1102 may include an electronic circuit for controlling the sensor included in the first ID recognition unit 1102 and an electronic circuit for processing the acquired information.

[0025] The first determination unit 1103 may include an inspection device that irradiates baggage with electromagnetic waves such as X-rays, terahertz waves, or millimeter waves to capture an image and determine whether or not the baggage contains a predetermined object. Alternatively, the first determination unit 1103 may include a metal detector that uses electromagnetic induction to determine whether or not the baggage contains a predetermined object. Alternatively, the first determination unit 1103 may include a liquid inspection device that utilizes the fact that the spectrum of light transmitted through a liquid differs depending on the type of liquid. Alternatively, the first determination unit 1103 may include a trace detection device that uses an air current or the like to blow away particles attached to the baggage and detect drugs, explosives, or the like from the particles.

[0026] The display device 1104 may have, for example, a display that displays the input information. The display device 1104 may also have a speaker that transmits the input information by voice. The display device 1104 displays, for example, a method of using the baggage determination device 11 and the first determination result by the first determination unit 1103 to a user of the baggage determination device 11.

[0027] Furthermore, the display device 1104 may be, for example, a touch panel having a touch sensor. In this case, a user of the baggage determination device 11 can operate the baggage determination device 11 by touching the display device 1104 with a fingertip or a stylus pen for input.

[0028] The display device 1104 may display a message to prompt the user of the baggage determination device 11 to perform ID authentication in the first ID recognition unit 1102, for example, as in the display content 11041 and the display content 11043 shown in FIG. 3A. The display device 1104 may also display that ID authentication in the first ID recognition unit 1102 has been completed, as in FIG. 3B. At this time, the display device 1104 may display information corresponding to the ID recognized by the first ID recognition unit 1102, as in the display content 11042. The display content 11042 may be, for example, a name, age, sex, or the like that is previously associated with the ID recognized by the first ID recognition unit 1102. In addition, for example, in the case of inspecting visitors to a movie theater or a concert venue, or passengers on a train or bus, the display content 11042 may be a seat, an available time of entry, a train or bus destination, or the like, that is previously associated with the ID. The display contents 11042 are not limited to text, and may be, for example, an image such as a face photo of the first ID holder associated with the first ID. Also, as shown in FIG. 3C, the display device 1104 may be equipped with, for example, a camera 11046. When the first ID recognition unit 1102 recognizes the ID based on face authentication, the display device 1104 may be equipped with a camera 11046, and an image of the user P1 of the baggage determination device 11 taken by the camera 11046 may be displayed in the display contents 11044. In order to improve the accuracy of face authentication by the first ID recognition unit 1102, the display device 1104 may instruct the user P1 to fit the face of P1 within a frame formed by the display contents 11045a, 11045b, 11045c, and 11045d. Also, as shown in FIG. 3D, the display device 1104 may display to the user P1 that ID authentication has been completed. 3E, the display device 1104 may instruct the baggage determination device 11 to place the user's baggage. When the display device 1104 is a touch panel having a touch sensor, the entrance management system 10 may be configured so that the user can operate the baggage determination device 11 with the display device 1104 to start, interrupt, end baggage determination, etc., as shown in FIG. 3F. Furthermore, as shown in FIG. 3G and FIG. 3H, the display device 1104 may instruct a user who has completed baggage determination on what to do after the determination is completed.For example, the display device 1104 may prompt a visitor whose baggage is determined to not contain specified objects to proceed to the entrance area, and may prompt a visitor whose baggage is determined to contain specified objects to proceed to a re-inspection area.

[0029] The baggage determination device 11 may include a conveyor 1105, an opening / closing door 1106, and a baggage storage area 1107, as shown in FIG. 4A, for example.

[0030] The baggage determination device 11 may determine whether the baggage contains a specified object by placing the baggage on a conveyor 1105 and transporting it to the first determination unit 1103. A user of the baggage determination device 11 places the baggage on the -Y axis side of the conveyor 1105. The conveyor 1105 transports the baggage to the first determination unit 1103 located on the +Y axis side as seen from the user. The baggage that has been determined by the first determination unit is transported in the -Y axis direction, and the user collects the baggage that has been determined by the first determination unit.

[0031] Furthermore, for example, when the first determination unit 1103 includes an X-ray inspection device, there is a risk that surrounding people may be exposed to X-rays if they are radiated to the outside from the first determination unit 1103. If the opening and closing door 1106 includes a material capable of blocking radiation, such as lead, it is possible to prevent surrounding people from being exposed to radiation by closing the opening and closing door 1106 during the determination process of the first determination unit. Furthermore, if the baggage determination device 11 includes a baggage storage area 1107, a user of the baggage determination device 11 can place their baggage in the baggage storage area 1107, making it easier to prepare for inspection of multiple pieces of baggage and to operate the baggage determination device 11.

[0032] Furthermore, the baggage determination device 11 may include a first conveyor 1105a and a second conveyor 1105b, as shown in FIG. 4B, for example. A user of the baggage determination device 11 first places the baggage on the -Y axis side of the first conveyor 1105a. The baggage is transported by the conveyor 1105a to the first determination unit 1103 located in the +Y axis direction as seen from the user, and it is determined whether the baggage contains a predetermined object. After the determination by the first determination unit is completed, the baggage is transported by the second conveyor 1105b along an axis 135° counterclockwise as seen from the +X axis, and then transported in the -Y axis direction to the baggage storage area 1108. In the configuration of Fig. 4A, the user of the baggage determination device 11 needs to move the baggage that has been determined by the first determination unit 1103 to the baggage storage area 1107, but in the configuration of Fig. 4B, multiple pieces of baggage are successively determined by the first determination unit 1103, and the baggage that has been determined is transported sequentially to the baggage storage area 1108 and can be collected together after the baggage determination. In this manner, multiple pieces of baggage can be determined by the first determination unit without the user needing to move the baggage that has been determined by the first determination unit to the baggage storage area 1107, making it possible to improve the inspection throughput.

[0033] The entrance management device 12 includes, for example, a processing unit 1201, a second ID recognition unit 1202, a first sensor 1203, a second determination unit 1204, and a display device 1205.

[0034] The processing unit 1201 is, for example, an electronic circuit such as an IC (Integrated circuit). Alternatively, the processing unit 1201 is an integrated circuit such as a CPU (Central Processing Unit), an FPGA (Field-programmable gate array), or a microcontroller. Alternatively, the processing unit 1201 may be a computer such as a server having a built-in CPU or GPU. The processing unit 1201 processes information input from, for example, the second ID recognition unit 1202, the second determination unit 1204, or the display device 1205, and outputs the processed information to the storage device 1001, the second determination unit 1204, or the display device 1205.

[0035] The processing unit 1201 may be hardware built into the second determination unit 1204, or may be hardware installed outside the second determination unit 1204 and connected via wire or wirelessly to the second ID recognition unit 1202, the first sensor 1203, the second determination unit 1204, the display device 1205, and the storage device 1001. For example, the processing unit 1201 may be a server capable of inputting and outputting processing information via the Internet.

[0036] One processing unit 1201 may be configured to be able to input information from a plurality of second ID recognition units 1202, a plurality of first sensors 1203, a plurality of second determination units 1204, and a plurality of display devices 1205. Also, one processing unit 1201 may be configured to be able to output information to a plurality of first sensors 1203, a plurality of second determination units 1204, and a plurality of display devices 1205.

[0037] The second ID recognition unit 1202 may be the same as the first ID recognition unit 1102. That is, the second ID may be the same as the first ID, and the second ID recognition unit 1202 may acquire the same information as the first ID recognition unit 1102. The second ID recognition unit 1202 includes, for example, a sensor that acquires ID information held by a user of the entrance management device 12. Furthermore, biometric information acquired by the second ID recognition unit 1202 may be used as the second ID. Furthermore, the second ID recognition unit 1202 may include an electronic circuit for controlling the sensor included in the second ID recognition unit 1202 and an electronic circuit for processing the acquired information.

[0038] The first sensor 1203 may be, for example, a camera that captures visible light or infrared light. Alternatively, the first sensor 1203 may be a sensor that irradiates a target with laser light and acquires the shape of the target and the distance between the target and the sensor based on information on the reflected light, such as LiDAR (Light Detection And Ranging). Alternatively, the first sensor 1203 may be a sensor called a ToF (Time of flight) sensor that acquires depth information of the target from the time it takes for light irradiated on the target to be reflected and returned. Alternatively, the first sensor 1203 may be a 3D sensor that measures the three-dimensional shape of the target.

[0039] The entrance management device 12 may include a plurality of first sensors 1203. For example, there may be one first sensor each for sensing the entrance entrant at the front and rear as viewed from the direction of travel of the entrance entrant, or the entrance entrant may be sensed from above by a first sensor installed on the ceiling or the like. By arranging a plurality of first sensors in this way, it is possible to reduce the possibility that the baggage carried by the entrance entrant will be hidden by the entrance entrant and become undetectable. In addition, the first sensor 1203 may be configured by combining a plurality of different types of sensors, such as a camera and LiDAR, or a camera and a 3D sensor.

[0040] The second determination unit 1204 determines whether the entrant is carrying baggage of a predetermined size or more, based on the information acquired by the first sensor 1203. The second determination unit 1204 is an integrated circuit such as a CPU, a GPU, an FPGA, or a microcontroller. Alternatively, the second determination unit 1204 may be a computer such as a server incorporating a CPU, a GPU, or the like. The second determination unit 1204 includes a program executed by the integrated circuit such as the CPU. The predetermined size may be changeable by an external input, etc.

[0041] The second determination unit 1204 determines whether or not the visitor is carrying baggage that is equal to or larger than a predetermined size determined by the manufacturer or administrator of the entrance management system 10. The predetermined size of the baggage is defined, for example, by its three-dimensional volume, or the expected area of ​​the baggage, or the length of the longest side of the baggage's outer shape. The predetermined size of the baggage may be set by appropriately combining the above-mentioned multiple definitions. If the predetermined size is defined as the expected area or three-dimensional volume, there is a risk that a rod-shaped object such as a sword or a firearm may not be detected as baggage of the predetermined size or larger. In addition, for example, when the first sensor is a camera, it is difficult to determine the three-dimensional volume of the baggage from a two-dimensional image of the baggage depending on the arrangement of the camera. In such a case, it is preferable to determine the size of the baggage by the expected area of ​​the baggage in the image captured by the first sensor, or the length of the longest side of the baggage's outer shape.

[0042] When the first sensor 1203 is composed of a camera, for example, an indicator with a known position and size is placed in the imaging range of the first sensor, and the size of the baggage carried by the visitor is compared with the size of the indicator based on the image captured by the first sensor, thereby making it possible to determine the size of the baggage carried by the visitor. Alternatively, for example, learning data consisting of images of people carrying baggage with a known size may be prepared, and artificial intelligence that estimates the size of the baggage carried by the person may be generated by machine learning technology and incorporated into the second determination unit 1204. In this way, the second determination unit 1204 can determine the size of the baggage carried by the visitor from the image captured by the first sensor 1203.

[0043] Furthermore, if the first sensor 1203 is configured with multiple cameras, it becomes easy to image the baggage from multiple directions and determine its three-dimensional size. The first sensor 1203 may be, for example, a camera called a stereo camera or 3D camera, which is configured by arranging two cameras in parallel and is capable of acquiring a three-dimensional image of the object by utilizing the parallax between the cameras.

[0044] Alternatively, for example, if the first sensor 1203 is composed of cameras installed in front of and behind the person and cameras installed above and below the person, a 3D image of the baggage can be captured by processing images captured by the multiple cameras in the processing unit 1201. By arranging multiple cameras at a distance in this manner, the possibility that the baggage of a visitor will be hidden by the visitor's body and will not be detectable can be reduced. Similarly, by arranging multiple LiDAR sensors and ToF sensors at a distance, the possibility that the baggage of a visitor will be hidden by the visitor's body and will not be detectable can be reduced.

[0045] For example, by using a LiDAR sensor or a ToF sensor, the three-dimensional shape of the object can be acquired, making it possible to determine the size of the baggage carried by the visitor. For example, when the first sensor 1203 is composed of a camera and a LiDAR sensor, the second determination unit 1204 can identify the baggage carried by the visitor from the image of the visitor acquired by the camera, and determine the size of the baggage by combining it with the three-dimensional shape information acquired by the LiDAR sensor.

[0046] The display device 1205 may have, for example, a display that displays the input information. The display device 1205 may also have a speaker that transmits the input information by voice. The display device 1205 may also be, for example, a touch panel having a touch sensor. In this case, a user of the entrance management device 12 can operate the entrance management device 12 by touching the display device 1205 with a fingertip or a stylus pen for input.

[0047] The display device 1205 displays the ID information of visitors and the first and second judgment results linked to the IDs to, for example, an administrator of the inspection system or an inspector. By using the display device 1205, an inspector can identify visitors whose baggage is judged by the first judgment unit to contain a predetermined object, and can easily call out to them, track them, monitor them using a surveillance camera, etc. Also, it is easy to identify visitors whose baggage is judged by the second judgment unit to be carrying baggage of a predetermined size or larger, and can easily call out to them or guide them to the baggage judgment device 11, etc.

[0048] FIG. 2 is a plan view that illustrates a schematic diagram of an example of an inspection system 300. As shown in FIG.

[0049] The inspection system 300 includes, for example, baggage determination devices 11a, 12a, and 13a, a first entrance section 304, second entrance sections 301a, 301b, and 301c, a waiting area 303, a re-inspection area 305, and an entrance 306 to the re-inspection area.

[0050] The entrance unit 301a includes, for example, a second ID recognition unit 1202a and a first sensor 1203a. Similarly, the entrance unit 301b includes, for example, a second ID recognition unit 1202b and a first sensor 1203b. Moreover, the entrance unit 301c includes, for example, a second ID recognition unit 1202c and a first sensor 1203c.

[0051] The baggage determination device 11a includes, for example, a first ID recognition unit 1102a and a first determination unit 1103a. Similarly, the baggage determination device 11b includes, for example, a first ID recognition unit 1102b and a first determination unit 1103b. Moreover, the baggage determination device 11c includes, for example, a first ID recognition unit 1102c and a first determination unit 1103c.

[0052] In the inspection system 300, a user of the inspection system 300 proceeds through the first entrance section 304 in the +X-axis direction to enter the interior of the inspection system 300. In the inspection system 300, the second entrance section 301c is located closer to the first entrance section 304 than the second entrance section 301a and the second entrance section 301b. If a user who does not have baggage of a predetermined size or larger enters through the second entrance section 301c, the travel distance required for entry can be shortened. A user who does not have baggage of a predetermined size or larger may enter by proceeding through either the second entrance section 301a or the second entrance section 301b in the +X-axis direction.

[0053] A user of the inspection system 300 may wait his / her turn for baggage identification using any of the baggage identification devices 11a, 11b, and 11c in the waiting area 303. The user uses any of the baggage identification devices 11a, 11b, and 11c to determine whether the baggage he / she possesses includes a predetermined item. After the baggage identification is completed, the user enters any of the second entrances 301a, 301b, and 301c by proceeding in the +X-axis direction.

[0054] For example, when entering through the second entry section 301a, the user of the inspection system 300 has his / her ID recognized by the second ID recognition section 1202a. When the second ID recognition section 1202a cannot recognize the ID, the processing section 1201 outputs information indicating that the user is not allowed to enter. When the second ID recognition section 1202a can recognize the user's ID, the processing section 1201 acquires a first judgment result associated with the first ID corresponding to the second ID from the storage device 1001 based on the recognized second ID. When the first judgment result is acquired, the processing section 1201 outputs information indicating whether the second ID holder is allowed to enter based on the first judgment result. When the first judgment result is not acquired, the processing section 1201 acquires a second judgment result determined by the second judgment section 1204 based on the information acquired by the first sensor 1203a, and outputs information indicating whether the second ID holder is allowed to enter based on the second judgment result. A second ID holder who has been output with information indicating that he or she is not allowed to enter undergoes reinspection at one of baggage inspection devices 11a, 11b, or 11c, or in reinspection area 305. Information on second ID holders who pass reinspection is stored in storage device 1001, and processing unit 1201 outputs information indicating that the second ID holder is allowed to enter when the second ID holder passes through one of second entrance units 301a, 301b, or 301c.

[0055] Here, we have explained the operation of the entrance management system 10 when a second ID holder passes through the second entrance section 301a, but the same applies when a second ID holder enters through the second entrance section 301b or the second entrance section 301c.

[0056] In the configuration of FIG. 2, the entrance management system 10 determines whether or not a second ID holder passing through second entrance sections 301a, 301b, 301c of the inspection system 300 is allowed to enter, and outputs information on whether or not the second ID holder is allowed to enter.

[0057] A first determination routine by the baggage determination device 11 for determining whether baggage includes a predetermined item will be described with reference to the flowchart shown in FIG.

[0058] The first ID recognition unit 1102 acquires information on the first ID held by the first ID holder (S101).

[0059] The processing unit 1101 determines whether the information of the first ID can be acquired (S102). If the first ID information cannot be acquired (S102: NO), the processing unit 1101 ends the first determination routine.

[0060] If the information of the first ID can be acquired (S102: YES), the processing unit 1101 judges whether the first ID is eligible for admission (S103). An ID being eligible for admission means that the ID is given an attribute indicating that the ID is eligible for admission. If the first ID is not eligible for admission (S103: NO), the processing unit 1101 ends the first judgment routine.

[0061] If the first ID is eligible for entry (S103: YES), the processing unit 1101 starts a baggage determination loop (S104). The first ID holder places the baggage on the baggage determination device 11 (S105). The first determination unit 1103 determines whether the baggage placed on the baggage determination device 11 includes a specified item (S106). The processing unit 1101 associates the first determination result by the first determination unit 1103 with the first ID, and stores it in the storage device 1001 (S107).

[0062] The processing unit 1101 judges whether the first ID holder has ended the baggage determination loop (S108). If the first ID holder has not ended the baggage determination loop (S108: NO), the processing unit 1101 repeats the baggage determination loop (S109). If the baggage determination loop has ended (S108: YES), the processing unit 1101 ends the first determination routine.

[0063] 6, an entry permission / denial determination routine will be described in which the entry management device 12 determines whether or not a pedestrian is permitted to enter the second entry section 301a in the inspection system 300. The entry permission / denial determination routine for the second entry sections 301b and 301c is similar to the entry permission / denial determination routine for the second entry section 301a.

[0064] The second ID recognition unit 1202a acquires the second ID information held by the passerby at the second entrance unit 301a (S110). The processing unit 1201 judges whether the second ID recognition unit 1202a has acquired the second ID information (S111). If it is judged that the second ID information has not been acquired (S111: NO), the processing unit 1201 outputs information indicating that the second ID is not allowed to enter (S112) and ends the entry permission / denial determination routine. If the second ID information has been acquired (S111: YES), the processing unit 1201 judges whether the second ID is eligible to enter (S113). If the second ID is not eligible to enter (S113: NO), the processing unit 1201 outputs information indicating that the second ID is not allowed to enter (S114) and ends the entry permission / denial determination routine.

[0065] If the second ID is eligible for entry (S113: YES), the processing unit 1201 acquires from the storage device 1001 a first judgment result associated with the first ID corresponding to the second ID (S115). If the first judgment result cannot be acquired (S116: NO), the processing unit 1201 executes a second judgment subroutine to judge whether the baggage held by the second ID holder is equal to or larger than a predetermined size (S117), and ends the entry permission judgment process. If the first judgment result can be acquired (S116: NO), the processing unit 1201 executes a subroutine to judge whether the baggage held by the second ID holder contains a predetermined object (S118), and ends the entry permission judgment process.

[0066] Next, with reference to the flowchart shown in FIG. 7, a second determination subroutine in which the entrance management device 12 determines whether or not the baggage carried by the second ID holder is equal to or larger than a predetermined size will be described.

[0067] The processing unit 1201 acquires information sensed by the first sensor 1203 (SR101). The second determination unit 1204 determines whether or not all baggage carried by the second ID holder is smaller than a predetermined size based on the acquired first sensor information (SR102). If at least one of the baggage carried by the second ID holder is equal to or larger than the predetermined size (SR103: NO), the processing unit 1201 outputs information indicating that the holder is not allowed to enter (SR104) and ends the second determination subroutine. If all baggage carried by the second ID holder is smaller than the predetermined size (SR103: YES), the processing unit 1201 outputs information indicating that the holder is allowed to enter (SR105) and ends the second determination subroutine.

[0068] Next, a predetermined object determination subroutine in which the entrance management device 12 determines whether or not a predetermined object is included in the baggage carried by the second ID holder will be described with reference to the flowchart shown in FIG.

[0069] The processing unit 1201 determines whether at least one piece of baggage of a predetermined size or larger carried by the second ID holder contains a predetermined object based on the first determination result acquired from the storage device 1001 (SR106). If at least one piece of baggage of a predetermined size or larger carried by the second ID holder contains a predetermined object (SR106: YES), the processing unit 1201 outputs information indicating that the second ID holder is not allowed to enter (SR107) and ends the subroutine for determining the predetermined object in the baggage of the second ID holder. If all pieces of baggage of a predetermined size or larger carried by the second ID holder do not contain the predetermined object (SR106: NO), the processing unit 1201 outputs information indicating that the second ID holder is allowed to enter (SR108) and ends the subroutine for determining the predetermined object in the baggage of the second ID holder.

[0070] As described above, according to the entrance management system 10 of the first embodiment, among users of the inspection system 300, for example, users who only carry baggage smaller than a predetermined size, such as a mobile phone, wallet, food and drink, writing implements, etc., do not need to have their baggage judged by the baggage judgment device 11. Since the number of users of the baggage judgment device 11 is reduced compared to an inspection system that does not use the entrance management system 10 of the first embodiment, the inspection throughput can be improved. Also, according to the entrance management system 10 of the first embodiment, the entrance management device 12 judges the size of the baggage of the user of the inspection system 300 and outputs the entry permission information. At this time, since the size of the baggage carried by the entrant does not necessarily need to be checked by the inspector, manpower saving is possible.

[0071] Second embodiment Next, a second embodiment will be described. Among the configurations of the second embodiment, the description of the configurations similar to those of the first embodiment will be omitted or simplified by incorporating the description of the first embodiment.

[0072] FIG. 9 is a plan view showing an outline of an inspection system 300a to which the entrance management system 10a according to the second embodiment is applied.

[0073] The first entrance section 304 of the inspection system 300a according to the second embodiment includes a passage section 13a and a passage section 13b. The first passage section 13a and the second passage section 13b correspond to the passage section 13 shown in Fig. 1. The passage section 13 includes, for example, a processing section 1301, a second sensor 1302, a third determination section 1303, and a display device 1304.

[0074] The passing section 13a includes, for example, a second sensor 1302a and a display device 1304a. Similarly, the passing section 13b includes, for example, a second sensor 1302b and a display device 1304b.

[0075] The processing unit 1301 is, for example, an electronic circuit such as an IC (Integrated circuit). Alternatively, the processing unit 1301 is, for example, an integrated circuit such as a CPU (Central Processing Unit), an FPGA (Field-programmable gate array), or a microcontroller. Alternatively, the processing unit 1301 may be a computer such as a server having a built-in CPU or GPU. The processing unit 1301 processes information input from, for example, the second sensor 1302, the third determination unit 1303, or the display device 1304, and outputs the processed information to the storage device 1001, the second sensor 1302, the third determination unit 1303, or the display device 1304.

[0076] The processing unit 1301 may be hardware built into the third determination unit 1303, or may be hardware installed outside the third determination unit 1303 and connected to the second sensor 1302, the third determination unit 1303, the display device 1304, and the storage device 1001 via wired or wireless communication. For example, the processing unit 1301 may be a server capable of inputting and outputting processing information via the Internet. One processing unit 1301 may be configured to be able to input information from a plurality of second sensors 1302, a plurality of third determination units 1303, and a plurality of display devices 1304. Also, one processing unit 1301 may be configured to be able to output information to a plurality of second sensors 1302, a plurality of third determination units 1303, and a plurality of display devices 1304.

[0077] The second sensor 1302 may be similar to the first sensor 1203. The second sensor 1302 is composed of, for example, a camera that captures visible light or infrared light, a LiDAR, a ToF sensor, a 3D sensor, etc. The second sensor 1302 may be composed of a plurality of sensors of the same type, like the first sensor 1203, or may be composed of a combination of a plurality of different types of sensors, such as a camera and a LiDAR, a camera and a 3D sensor, etc.

[0078] In the inspection system 300a, a user of the inspection system 300a advances through the passage section 13a or 13b of the first entrance section 304 in the +X-axis direction and enters the interior of the inspection system 300a. At this time, a judgment is made by the third judgment section 1303. The third judgment section 1303 is, for example, an integrated circuit such as a CPU, a GPU, an FPGA, or a microcontroller. Alternatively, the third judgment section 1303 may be a computer such as a server having a built-in CPU or GPU. The third judgment section 1303 includes a program executed by the integrated circuit such as the CPU.

[0079] In the second embodiment, the determination by the third determination unit 1303 is performed before the determination by the first determination unit 1103.

[0080] The third determination unit 1303 determines whether a person passing through the passage unit 13 is carrying baggage of a predetermined size or more, based on the information acquired by the second sensor 1302. The determination by the third determination unit 1303 may be made by an attendant based on the information acquired by the second sensor 1302, or the third determination unit 1303 may be a program running in the processing unit 1301 of the passage unit 13.

[0081] Here, as the predetermined size of baggage, for example, a first predetermined size, a second predetermined size, and a third predetermined size that are different from each other may be defined. In the following, it is assumed that the third predetermined size is larger than the second predetermined size, and the second predetermined size is larger than the first predetermined size.

[0082] The third determination unit 1303 makes a determination as to three conditions: whether or not the baggage carried by a passerby in the passage area 13 is less than a first predetermined size; whether or not the baggage is equal to or greater than the first predetermined size and less than a second predetermined size; and whether or not the baggage is equal to or greater than the second predetermined size and less than a third predetermined size.

[0083] For example, the inspection system 300a is configured so that baggage inspection is not required for a person who only carries baggage smaller than a first predetermined size. Here, the first predetermined size is the same as the predetermined size in the first embodiment. Among the baggage determination devices 11 provided in the inspection system 300a, the baggage determination devices 11aa and 11ab are capable of determining whether baggage smaller than a second predetermined size contains a predetermined object, and the baggage determination device 11ac is capable of determining whether baggage smaller than a third predetermined size contains a predetermined object.

[0084] In this case, if the passage section 13 is configured to guide the passerby through one of the second entry sections 301a, 301b, or 301c when the passerby is carrying only baggage less than the first predetermined size, to guide the passerby through one of the baggage determination devices 11aa, 11ab when the passerby is carrying baggage that is equal to or larger than the first predetermined size and smaller than the second predetermined size, to guide the passerby through one of the baggage determination devices 11aa, 11ab when the passerby is carrying baggage that is equal to or larger than the second predetermined size and smaller than the third predetermined size, and to guide the passerby through one of the baggage determination devices 11ac when the passerby is carrying baggage that is equal to or larger than the second predetermined size, and to guide the passerby through one of the baggage determination devices 11ac when the passerby is carrying baggage that is equal to or larger than the second predetermined size, then the passerby through the passage section 13 can know in advance whether or not he or she should carry out baggage determination, and the process of baggage determination that should be carried out after passing through the passage section 13, etc.

[0085] The display device 1304 may have, for example, a display that displays information input from the processing unit 1301. The display device 1304 may also have a speaker that transmits the input information by voice. The display device 1304 may also be, for example, a touch panel having a touch sensor.

[0086] The display device 1304 may display to a pedestrian on the passage section 13 whether or not the passage section 13 is passable, for example, as in display content 13041 and display content 13042 shown in Fig. 10A or display content 13041, display content 13042, and display content 13043 shown in Fig. 10B. The display method may be not only text but also symbols, pictograms, and the like.

[0087] 10C and 10D, information based on the third determination result by the third determination unit 1303 may be displayed to passersby in the passage section 13. In this way, passersby in the passage section 13 can know in advance whether or not they need to use the baggage determination device 11. Passersby who only have baggage smaller than a predetermined size can know in advance that they do not need to wait in the waiting area 303 to use the baggage determination device 11, and can smoothly enter through any of the second entrance sections 301a, 301b, and 301c.

[0088] 10E and 10F , the baggage assessment process to be performed after passing through passage section 13 may be displayed to pedestrians passing through passage section 13. Passengers passing through passage section 13 can move smoothly by knowing in advance the baggage assessment process to be performed by them.

[0089] Furthermore, the display device 1304 may display information based on the third judgment result by the third judgment unit 1303 not only to the pedestrian passing through the passage section 13 but also to the staff. In this manner, the staff can appropriately guide the pedestrian passing through the passage section 13 about the route to take and the examination to be taken in accordance with the third judgment result.

[0090] With reference to the flowchart shown in FIG. 11, a third determination routine in the passage section, in which the passage section 13 determines the size of baggage carried by a person passing through the passage section 13, will be described.

[0091] The processing unit 1301 acquires information on baggage carried by a pedestrian in the passing section 13 via the second sensor (S201). The third determination unit 1303 determines the size of the baggage carried by the pedestrian in the passing section 13 (S202).

[0092] The third determination unit 1303 determines whether all baggage carried by the passerby is smaller than the first predetermined size (S203). If all baggage is smaller than the first predetermined size (S203: YES), the processing unit 1301 outputs information that baggage inspection is not required (S204) and ends the third determination routine in the passage area.

[0093] When at least one piece of baggage carried by the passer is equal to or larger than the first predetermined size (S203: NO), the processing unit 1301 outputs information indicating that baggage inspection is necessary (S205). The third determination unit 1303 determines whether or not all pieces of baggage carried by the passer in the passage unit 13 are smaller than the second predetermined size (S206). When all pieces of baggage are smaller than the second predetermined size (S206: YES), the processing unit 1301 outputs information indicating that small baggage self-inspection is possible (S207), and ends the third determination routine in the passage unit. When at least one piece of baggage is equal to or larger than the second predetermined size (S206: NO), the third determination unit 1303 determines whether or not all pieces of baggage are smaller than the third predetermined size (S208). When all baggage is smaller than the third predetermined size (S208: YES), the processing unit 1301 outputs information that large baggage self-inspection is possible (S209) and ends the third judgment routine in the passage area. When at least one baggage is equal to or larger than the third predetermined size (S208: YES), the processing unit 1301 outputs information that baggage self-inspection is not possible (S210) and ends the third judgment routine in the passage area.

[0094] By the third determination routine in the passage area, the inspection system 300a is configured to be able to select an inspection method according to the size of the baggage carried by the user.

[0095] As described above, according to the entrance management system 10a of the second embodiment, in the inspection system 300a to which the entrance management system 10a is applied, the third determination unit 1303 can determine the size of baggage carried by a user of the inspection system 300a before the user performs baggage determination using the baggage determination device 11.

[0096] Furthermore, by displaying the third determination result by the third determination unit 1303 to pedestrians passing through the passage section 13 using the display device 1304, the pedestrians passing through the passage section 13 can know in advance whether or not baggage determination is necessary before carrying out the baggage determination, and the baggage determination process to be carried out after passing through the passage section 13. Furthermore, by displaying the third determination result by the third determination unit 1303 to the staff member on the display device 1304, it becomes easier for the staff member to give guidance to the pedestrians passing through the passage section 13.

[0097] By configuring the entrance management system 10a in this way, the user of the inspection system 300a can act efficiently by knowing the baggage judgment process and movement route that he / she should carry out in advance. Furthermore, by applying the entrance management system 10a, the inspection system 300a can improve the inspection throughput by encouraging the user to select an appropriate action. Furthermore, since the visitor can know the baggage judgment process and movement route that he / she should carry out in the inspection system 300a by the display device 1304, it is not necessary for the staff to guide the visitor on the baggage judgment process and movement route, and manpower can be reduced. Furthermore, the third judgment routine in the passage area allows the inspection system 300a to select an inspection method according to the size of the baggage carried by the user.

[0098] Third embodiment Next, a third embodiment will be described. Among the configurations of the third embodiment, the description of the configurations similar to those of the first embodiment will be omitted or simplified by incorporating the description of the first embodiment.

[0099] FIG. 12 is a plan view showing an outline of an inspection system 300b to which an entrance management system 10b according to the third embodiment is applied.

[0100] The inspection system 300b includes, for example, baggage determination devices 11ba, 11bb, 11bc, a first entry section 304, a second entry section 301a, 301b, 301c, a waiting area 303, a re-inspection area 305, an entrance 306 to the re-inspection area, a specified object carrying determination section 1402a1, 1402a2, 1402b1, 1402b2, 1402c1, 1402c2, 1402d1, 1402d2 of the body determination device, opening / closing sections 1504a1, 1504a2, 1504b1, 1504b2, 1504c1, 1504c2 of the gate device, and display devices 1505a, 1505b, 1505c of the gate device.

[0101] The entrance unit 301a includes, for example, a second ID recognition unit 1202a, a first sensor 1203a, gate device opening / closing units 1504a1 and 1504a2, and a display device 1505a. Similarly, the entrance unit 301b includes, for example, a second ID recognition unit 1202b, a first sensor 1203b, gate device opening / closing units 1504b1 and 1504b2, and a display device 1505b.

[0102] The entrance section 301c includes, for example, a second ID recognition section 1202c, a first sensor 1203c, opening / closing sections 1504c1 and 1504c2 of the gate device, a display device 1505c, and predetermined object carrying determination sections 1402d1 and 1402d2 of the body determination device.

[0103] The baggage determination device 11ba includes, for example, a first ID recognition unit 1102a, a first determination unit 1103a, and predetermined object carrying determination units 1402a1 and 1402a2 of the body determination device. Similarly, the baggage determination device 11bb includes, for example, a first ID recognition unit 1102b, a first determination unit 1103b, and predetermined object carrying determination units 1402b1 and 1402b2 of the body determination device. In addition, the baggage determination device 11bc includes, for example, a first ID recognition unit 1102c, a first determination unit 1103c, and predetermined object carrying determination units 1402c1 and 1402c2 of the body determination device.

[0104] The body determination device 14 includes, for example, a processing unit 1401, a predetermined object carrying determination unit 1402, and a display device 1403.

[0105] The processing unit 1401 is, for example, an electronic circuit such as an IC (Integrated circuit). Alternatively, the processing unit 1401 is, for example, an integrated circuit such as a CPU (Central Processing Unit), an FPGA (Field-programmable gate array), or a microcontroller. Alternatively, the processing unit 1401 may be a computer such as a server having a built-in CPU or GPU. The processing unit 1401 processes information input from, for example, the predetermined object carrying determination unit 1402 or the display device 1403, and outputs the processed information to the storage device 1001, the predetermined object carrying determination unit 1402, or the display device 1403.

[0106] The processing unit 1401 may be hardware built into the body determination device 14, or may be hardware installed outside the body determination device 14 and connected to the predetermined object carrying determination unit 1402, the display device 1403, and the storage device 1001 via wired or wireless communication. For example, the processing unit 1401 may be a server capable of inputting and outputting processing information via the Internet. One processing unit 1401 may be configured to be able to input information from a plurality of predetermined object carrying determination units 1402 and a plurality of display devices 1403. Also, one processing unit 1401 may be configured to be able to output information to a plurality of predetermined object carrying determination units 1402 and a plurality of display devices 1403.

[0107] The unit 1402 for determining whether a person is carrying a predetermined object includes an inspection device that irradiates electromagnetic waves such as X-rays, terahertz waves, or millimeter waves on the person being inspected by the body judgment device 14 to capture an image and determine whether the person being inspected by the body judgment device 14 is carrying a predetermined object. Alternatively, the unit 1402 for determining whether a person is carrying a predetermined object may include a metal detector that uses electromagnetic induction to determine whether the person being inspected by the body judgment device 14 is carrying a predetermined object. Alternatively, the unit 1402 for determining whether a person is carrying a predetermined object may include a trace detection device that uses an air current or the like to blow away particles adhering to the person being inspected by the body judgment device 14 and detects drugs, explosives, or the like from the particles.

[0108] The display device 1403 may have, for example, a display that displays information input from the processing unit 1401. The display device 1403 may also have a speaker that transmits the input information by voice. The display device 1403 may also be, for example, a touch panel having a touch sensor.

[0109] The gate device 15 includes, for example, a processing unit 1501, an approach detection unit 1502, an opening / closing control unit 1503, an opening / closing unit 1504, and a display device 1505.

[0110] The processing unit 1501 may be the same as, for example, the processing unit 1101. The processing unit 1501 processes information input from, for example, the approach detection unit 1502, the opening / closing control unit 1503, or the display device 1505, and outputs the processed information to the storage device 1001, the approach detection unit 1502, the opening / closing control unit 1503, or the display device 1505.

[0111] Furthermore, the processing unit 1501 may acquire the second ID information acquired by the second ID recognition unit 1202 via the storage device 1001. When each second entrance unit includes a second ID recognition unit and an opening / closing unit of the gate device as in Fig. 12, the processing unit 1501 of the gate device can acquire the first judgment result or the body judgment result linked to the first ID corresponding to the second ID based on the second ID information acquired by the second ID recognition unit, and execute the gate opening / closing process based on the acquired results.

[0112] The approach detection unit 1502 is, for example, a camera or an infrared sensor, and detects that a entrant approaches the gate device 15. The approach detection unit 1502 outputs information regarding whether or not the entrant is approaching the gate device 15 to the processing unit 1501. The approach detection unit 1502 may detect not only that a entrant has approached the gate device 15, but also whether or not the entrant has passed through the gate device 15.

[0113] The opening / closing control unit 1503 is, for example, a CPU or a microcontroller, and controls the opening and closing operation of the opening / closing unit 1504. The processing unit 1501 controls the opening / closing control unit 1503 based on the output information of the approach detection unit 1502, thereby enabling control such as closing the gate opening / closing unit 1504 when a visitor approaches the gate device 15, and opening the gate opening / closing unit 1504 when a visitor is not approaching the gate device 15.

[0114] The opening / closing section 1504 is a mechanism for preventing a person passing through the gate device 15 from illegally passing through the gate device 15. The structure of the opening / closing section may be a turnstile type, a retractable type, a flap door type, or the like.

[0115] The display device 1505 may have, for example, a display that displays information input from the processing unit 1501. The display device 1505 may also have a speaker that transmits the input information by voice. The display device 1505 may also be, for example, a touch panel having a touch sensor. The display device 1505 displays, for example, information regarding the passability of the gate device 15 to an entrant.

[0116] The inspection system 300b according to the third embodiment has three second entrance sections. Of the three second entrance sections, only the second entrance section 301c has the predetermined object carrying determination section 1402d1 and the predetermined object carrying determination section 1402d2 of the body determination device. The inspection system 300b is configured so that users of the inspection system 300b who have at least one piece of baggage of a predetermined size or larger can pass through the second entrance section after the baggage determination devices 11ba, 11bb, and 11bc determine whether the baggage contains a predetermined object. In addition, the predetermined object carrying determination sections 1402a1 and 1402a2 of the body determination device determine whether the user of the baggage determination device 11ba carries a predetermined object. In addition, the predetermined object carrying determination sections 1402b1 and 1402b2 of the body determination device determine whether the user of the baggage determination device 11bb carries a predetermined object. In addition, whether or not the user of the baggage determination device 11bc is carrying a predetermined object is determined by the predetermined object carrying determination units 1402c1 and 1402c2 of the body determination device.

[0117] A user whose baggage is all smaller than the predetermined size can pass through the second entrance 301c without using the baggage determination devices 11ba, 11bb, and 11bc. For a user whose baggage is all smaller than the predetermined size, the predetermined object carrying determination units 1402d1 and 1402d2 of the body determination device provided in the second entrance 301c determine whether or not the user is carrying a predetermined object. When a user whose baggage is all smaller than the predetermined size passes through either of the second entrances 301a and 301b, the determination as to whether or not the user is carrying a predetermined object is not performed for the user whose baggage is all smaller than the predetermined size. In the inspection system 300b, since all of the baggage determination devices 11ba, 11bb, and 11bc are provided with the predetermined object carrying determination units of the body determination device, the user who has undergone the first determination as to whether or not the user is carrying a predetermined object in the baggage determination devices 11ba, 11bb, and 11bc is also determined by the body determination device. Therefore, when the first judgment result associated with the first ID corresponding to the second ID held by any of the passers-by at the second entrance sections 301a, 301b is not obtained, that is, when the baggage judgment devices 11ba, 11bb, 11bc have not judged whether the passer-by is carrying a predetermined object in the baggage, the processing unit 1501 of the gate device 15 outputs information that the passer-by is not allowed to enter. In this way, it becomes possible for the body judgment device 14 to judge whether the passer-by is carrying a predetermined object for all users of the inspection system 300b, regardless of the size of the baggage they carry.

[0118] The first determination routine in the entrance management system 10b will be described with reference to the flowchart shown in Fig. 14. The first determination routine according to the third embodiment differs from the first determination routine according to the first embodiment in that it involves two determination processes: a baggage determination device determines whether the baggage of the first ID holder includes a specified object, and a body determination device determines whether the first ID holder is carrying a specified object.

[0119] The first ID recognition unit 1102 acquires information about the first ID held by the first ID holder (S101b).

[0120] The processing unit 1101 determines whether the information of the first ID can be acquired (S102b). If the first ID information cannot be acquired (S102b: NO), the processing unit 1101 ends the first determination routine.

[0121] If the information of the first ID can be acquired (S102b: YES), the processing unit 1101 judges whether the first ID is qualified to enter (S103b). If the first ID is not qualified to enter (S103b: NO), the processing unit 1101 ends the first judgment routine.

[0122] If the first ID is eligible for entry (S103b: YES), the processing unit 1101 starts a baggage determination loop (S104b). The first ID holder places the baggage in the baggage determination device 11 (S105b). The specified object carrying determination unit 1402 determines whether the first ID holder is carrying a specified object (S106b). The processing unit 1401 of the body determination device associates the first ID with the body determination result and stores them in the storage device 1001 (107b).

[0123] The first determination unit 1103 determines whether the baggage placed on the baggage determination device 11 includes a predetermined object (S108b). The processing unit 1101 associates the first determination result by the first determination unit 1103 with the first ID, and stores the result in the storage device 1001 (S109b).

[0124] The processing unit 1101 judges whether or not the first ID holder has ended the baggage determination loop (S110b). If the first ID holder has not ended the baggage determination loop (S110b: NO), the processing unit 1101 repeats the baggage determination loop (S111b). If the baggage determination loop has ended (S110b: YES), the processing unit 1101 ends the first determination routine.

[0125] 15A and 15B, an entry permission / denial determination routine for determining whether or not a passerby is permitted to enter the second entrance section 301a in the inspection system 300b according to the third embodiment will be described. The entry permission / denial determination routine for the second entrance sections 301b and 301c is similar to the entry permission / denial determination routine for the second entrance section 301a.

[0126] The second ID recognition unit 1202a of the entrance management device 12 acquires ID information held by a passerby at the second entrance section 301a (S301). The processing unit 1201 judges whether or not the ID information has been acquired (S302). If the ID information has not been acquired (S302: NO), the processing unit 1201 outputs information indicating that the passerby is not allowed to enter (S303) and ends the entrance permission / prohibition judgment routine.

[0127] If the second ID recognition unit 1202a determines that the second ID information has been acquired (S302: YES), the processing unit 1201 determines whether or not the second ID is eligible for admission (S304). If the second ID is determined not to be eligible for admission (S304: NO), the processing unit 1201 outputs information indicating that admission is not permitted (S305), and ends the admission permission determination routine.

[0128] If the second ID is eligible for entry, the processing unit 1201 acquires from the storage device 1001 a first judgment result associated with the first ID corresponding to the second ID (S306). The processing unit 1201 judges whether the first judgment result has been acquired (S307). If the first judgment result has been acquired (S307: YES), the processing unit 1201 acquires from the storage device 1001 a body judgment result associated with the second ID (S311). The processing unit 1201 judges whether the second ID holder is carrying a predetermined object based on the body judgment result (S312). If the second ID holder is carrying a predetermined object (S312: NO), the processing unit 1201 outputs information indicating that entry is not permitted (S313) and ends the entry permission / prohibition judgment routine. If the second ID holder is not carrying the specified item (S312: YES), the processing unit 1201 executes the subroutine for determining whether the second ID holder has the specified item in his / her baggage shown in FIG. 8 (S314), and ends the entry permission determination routine.

[0129] If the first judgment result cannot be obtained (S312: NO), the second judgment unit 1204 acquires first sensor information from the first sensor 1203a via the processing unit 1201 (S308). Based on the acquired first sensor information, the second judgment unit 1204 judges whether all baggage carried by the passerby at the second entrance 301a is smaller than a predetermined size (S309). Based on the judgment result of the second judgment unit 1204, if at least one piece of baggage is equal to or larger than the predetermined size (S309: NO), the processing unit 1201 outputs information indicating that entry is not permitted (S310) and ends the entry permission judgment routine.

[0130] When all baggage is smaller than the predetermined size (S309: YES), the processing unit 1201 judges whether the passage section through which the second ID holder is passing is equipped with a body determination device (S315). Since the second entry sections 301a and 301b are not equipped with a body determination device (S315: NO), if the second ID holder is passing through 301a or 301b, the processing unit 1201 outputs information indicating that the second ID holder is not allowed to enter (S316) and ends the entry permission / denial determination routine. Since the second entry section 301c is equipped with a body determination device (S315: YES), if the second ID holder is passing through 301c, the processing unit 1201 executes the subroutine for determining whether a predetermined object is being carried at the second entry section shown in FIG. 16 (S317) and ends the entry permission / denial determination routine.

[0131] Here, steps S308 to S310 correspond to the second determination subroutine in FIG.

[0132] Next, with reference to the flowchart shown in FIG. 16, a subroutine for determining whether a user of the body determination device provided in the second entrance section 301c is carrying a predetermined object at the second entrance section 301c will be described.

[0133] The predetermined object carrying determination units 1402d1 and 1042d2 provided in the second entrance section 301c determine whether or not the second ID holder passing through the second entrance section 301c is carrying a predetermined object (SR301). The processing unit 1401 determines whether or not the second ID holder is carrying a predetermined object based on the body determination results of the predetermined object carrying determination units 1402d1 and 1042d2 (SR302). If the second ID holder is carrying a predetermined object (SR302: YES), the processing unit 1401 outputs information that the holder is not allowed to enter (SR303). If the second ID holder is not carrying a predetermined object (SR302: NO), the processing unit 1401 outputs information that the holder is allowed to enter (SR304). The processing unit 1401 associates the first ID corresponding to the second ID held by the second ID holder with the body judgment result, stores them in the storage device 1001 (SR305), and ends the subroutine for judging whether a specified item is carried at the second entrance.

[0134] Next, a processing routine for opening and closing the gate provided in the second entrance section will be described with reference to the flowchart shown in FIG.

[0135] The approach detection unit 1502 intermittently detects that a pedestrian approaches the gate device (S320). When the approach of a person is detected, the processing unit 1501 closes the gate opening / closing unit 1504 via the opening / closing control unit 1503 (S321). After that, the entry permission / rejection determination routine shown in FIG. 15A and FIG. 15B is executed (S322). The processing unit 1501 acquires the entry permission / rejection information of the second ID holder outputted in the entry permission / rejection determination routine via the storage device 1001 (S323). The processing unit 1501 displays the acquired entry permission / rejection information on the display device 1505 (S324). The processing unit 1501 judges whether the acquired entry permission / rejection information indicates that entry is permitted or not (S325). If the entry permission / rejection information indicates that entry is not permitted (S325: NO), the processing unit 1501 ends the gate opening / closing processing routine. If the entry permission information indicates that the entry is permitted (S325: YES), the processing unit 1501 opens the gate opening / closing unit 1504 via the opening / closing control unit 1503 (S326). The processing unit 1501 starts a second ID holder passage detection loop (S327). The processing unit 1501 determines whether the second ID holder has passed through the gate device 15 based on the information acquired by the approach detection unit 1502 (S328). If the second ID holder has not passed through the gate device 15 (S328: NO), the processing unit 1501 continues the second ID holder passage detection loop. If the second ID holder has passed through the gate device 15 (S328: YES), the processing unit 1501 ends the second ID holder passage detection loop (S329). The processing unit 1501 closes the gate opening / closing unit 1504 via the opening / closing control unit 1503 (S330), and ends the gate opening / closing process.

[0136] As described above, according to the entrance management system 10b of the third embodiment, in the inspection system 300b to which the entrance management system 10b is applied, by combining judgment by a baggage judgment device with judgment by a walk-through type body judgment device, it is possible to detect specified objects concealed in the clothing of a person carrying only baggage less than a specified size without reducing inspection throughput.

[0137] Furthermore, by integrating the baggage judgment device and the body judgment device as shown in Fig. 13, body inspection can be performed without fail on users of the baggage judgment device, preventing oversights. Also, body inspection at the entrance is not required for users of the baggage judgment device, improving inspection throughput. Furthermore, by providing a body judgment device at the second entrance, judgment can be performed by the body judgment device on all entrants whose baggage is smaller than a predetermined size and who do not use the baggage judgment device.

[0138] Furthermore, by providing a gate device at the entrance, it is possible to prevent unauthorized entry by visitors who have been determined not to be allowed entry.

[0139] Furthermore, by providing a display device at the gate device, visitors can learn about their own admission status. Also, because the display device allows visitors to know the route they should take after admission and what to do if they are denied admission, there is no need for staff to guide visitors, which reduces manpower.

[0140] (Fourth embodiment) Next, a fourth embodiment will be described. Among the configurations of the fourth embodiment, the description of the configurations similar to those of the first embodiment will be omitted or simplified by incorporating the description of the first embodiment.

[0141] Fig. 18 is a diagram showing a schematic configuration of an entrance management system 10c according to a fourth embodiment. In the entrance management system 10c according to the fourth embodiment shown in Fig. 18, some of the same components as those in the entrance management system 10 according to the first embodiment are omitted. Fig. 19 is a plan view showing a schematic configuration of an inspection system 300c to which the entrance management system 10c according to the fourth embodiment is applied.

[0142] As shown in FIG. 18, a baggage determination device 11c provided in an entrance control system 10c according to the fourth embodiment includes a third sensor 1110 and a fourth determination unit 1111, for example.

[0143] The third sensor 1110 may be similar to the first sensor 1203. The third sensor 1110 is configured, for example, with a camera that captures visible light or infrared light, a LiDAR, a ToF sensor, a 3D sensor, etc. The third sensor 1110 may be configured with a plurality of sensors of the same type, similar to the first sensor 1203, or may be configured with a combination of a plurality of different types of sensors, such as a camera and a LiDAR, a camera and a 3D sensor, etc.

[0144] The third sensor 1110 may be installed, for example, in front of, behind, or above the user of the baggage determination device 11c, and may acquire information on baggage carried by the user of the baggage determination device 11c. The third sensor 1110 may also be installed inside the first determination unit 1103, and may acquire information on baggage determined by the first determination unit. The third sensor 1110 captures an image of baggage carried by the user of the baggage determination device 11c. The third sensor 1110 outputs the captured image to the processing unit 1101, and is controlled by the processing unit 1101.

[0145] The fourth determination unit 1111 may be the same as the second determination unit 1204, for example. The fourth determination unit 1111 determines whether all baggage of a predetermined size or larger carried by the entrant has been determined by the first determination unit 1103 provided in the baggage determination device 11c, based on information acquired by the third sensor 1110. The fourth determination unit 1111 is, for example, an integrated circuit such as a CPU, a GPU, an FPGA, or a microcontroller. Alternatively, the fourth determination unit 1111 may be a computer such as a server incorporating a CPU, a GPU, or the like. The fourth determination unit 1111 includes a program executed by the integrated circuit such as the CPU.

[0146] The fourth determination unit 1111, for example, determines the number of pieces of baggage of a predetermined size or more held by the first ID holder using the baggage determination device 11c based on the information on the baggage acquired by the third sensor 1110. The fourth determination unit 1111 also determines whether or not baggage of a predetermined size or more has been determined by the first determination unit based on the output information of the first determination unit 1103. The fourth determination unit 1111 determines whether or not the first determination unit 1103 has performed a determination process for each piece of baggage of a predetermined size or more held by the first ID holder using the baggage determination device 11c. When the fourth determination result is not obtained for at least one piece of baggage of a predetermined size or more, that is, when at least one piece of baggage of a predetermined size or more has not been determined by the first determination unit 1103, the fourth determination unit 1111 outputs information indicating that entry is not permitted in an entry permission determination routine in the second entry unit described later.

[0147] Based on information obtained from the third sensor 1110 and the fourth determination unit 1111, the processing unit 1101 may display on the display device 1104 baggage of a certain size or larger that has not been determined by the first determination unit 1103, as shown in Figures 20A and 20B, for example.

[0148] The display device 1104 may display a message to the user of the baggage determination device 11 to urge the user to inspect the baggage, for example, as in display content 11041 and display content 11043 shown in Fig. 20A. The display device 1104 may also display uninspected baggage using an image of the first ID holder or a silhouette of a person and baggage, as in display content 11044. The display device 1104 may also highlight uninspected baggage using a display means such as enclosing it in a frame or indicating it with an arrow, as in display content 11045.

[0149] Furthermore, the display device 1104 may display multiple pieces of uninspected baggage, as in display contents 11044a and 11044b shown in Fig. 20B. For example, when the baggage determination device 11c includes a baggage storage area 1108 as shown in Fig. 4B, the display contents 11044a may display uninspected baggage worn or touched by the first ID holder, and the display contents 11044b may display uninspected baggage placed in the baggage storage area 1108. Furthermore, multiple pieces of uninspected baggage may be highlighted, as in display contents 11045a and 11045b.

[0150] In this manner, a user of the inspection system 300c can determine whether or not a specific object is contained in baggage of a specific size or larger, without exception, for all baggage.

[0151] The first determination routine in the entrance management system 10c according to the fourth embodiment will be described with reference to the flowcharts shown in Figures 21A and 21B. The first determination routine in the fourth embodiment differs from the first determination routine in the first embodiment in that the baggage determination device 11c simultaneously determines whether the baggage of the first ID holder contains a predetermined object, and a fourth determination is made to determine whether all baggage of a predetermined size or larger held by the first ID holder has been determined by the first determination unit.

[0152] The first ID recognition unit 1102 acquires information on the first ID held by the first ID holder (S401).

[0153] The processing unit 1101 determines whether the information of the first ID has been acquired (S402). If the first ID information has not been acquired (S402: NO), the processing unit 1101 ends the first determination routine.

[0154] If the information of the first ID can be acquired (S402: YES), the processing unit 1101 judges whether the first ID is qualified to enter (S403). If the first ID is not qualified to enter (S403: NO), the processing unit 1101 ends the first judgment routine.

[0155] If the first ID has the entry qualification (S403: YES), the processing unit 1101 starts a baggage judgment loop (S404). The processing unit 1101 judges whether the first ID holder has interrupted the judgment loop (S405). If the judgment loop has been interrupted (S405: YES), the processing unit 1101 ends the baggage judgment loop (S413) and ends the first judgment routine. If the baggage judgment loop has not been interrupted (S405: NO), the first ID holder places the baggage on the baggage judgment device 11 (S406). The first judgment unit 1103 judges whether the baggage includes a predetermined object (S407). The processing unit 1101 associates the first judgment result with the first ID and stores it in the storage device 1001 (S408). The processing unit 1101 executes a fourth judgment subroutine shown in FIG. 22 (S409). The processing unit 1101 determines whether or not all baggage of the first ID holder that is equal to or larger than the predetermined size has been determined by the first determination unit 1103 based on the fourth determination result (S410). If all baggage of the first ID holder that is equal to or larger than the predetermined size has been determined by the first determination unit 1103 (S410: YES), the processing unit 1101 ends the baggage determination loop (S411) and ends the first determination routine. If at least one baggage of the predetermined size or larger has not been determined by the first determination unit 1103 (S410: NO), the processing unit 1101 repeats the baggage determination loop.

[0156] Next, a fourth determination routine in the entrance management system 10c according to the fourth embodiment will be described with reference to the flowchart shown in FIG.

[0157] The processing unit 1101 acquires information on baggage of a predetermined size or larger belonging to the first ID holder acquired by the third sensor 1110 (SR401). The fourth determination unit 1111 determines whether or not the baggage of the first ID holder has been determined by the first determination unit 1103 based on the information acquired by the third sensor 1110 (SR402). The processing unit 1101 associates the first ID, the information on the baggage, and the fourth determination result, and stores them in the storage device 1001 (SR403), and ends the fourth determination subroutine.

[0158] Next, the entry permission / prohibition determination routine in the entry management system 10c according to the fourth embodiment will be described with reference to the flowcharts shown in Figs. 23A and 23B.

[0159] Of the entry permission determination routine according to the fourth embodiment, steps S420 to S427 correspond to steps S110 to S117 of the entry permission determination routine according to the first embodiment shown in FIG. 6, and therefore will be omitted.

[0160] When the first judgment result associated with the first ID corresponding to the second ID can be acquired (S426: YES), the processing unit 1201 acquires from the storage device 1001 a fourth judgment result associated with the first ID corresponding to the second ID (S428). The processing unit 1201 judges whether all baggage of a predetermined size or more possessed by the second ID holder has been judged by the first judgment unit 1103 based on the fourth judgment result (S429). When at least one baggage of a predetermined size or more has not been judged by the first judgment unit 1103 (S429: NO), the processing unit 1201 outputs information that the entry is not permitted (S430) and ends the entry permission / denial judgment routine. When all baggage of a predetermined size or more has been judged by the first judgment unit 1103 (S429: YES), the processing unit 1201 executes the predetermined object judgment subroutine for the baggage of the second ID holder shown in FIG. 8 (S431) and ends the entry permission / denial judgment routine.

[0161] As described above, according to the entrance management system 10c of the fourth embodiment, in the inspection system 300c to which the entrance management system 10c is applied, it becomes possible for a user of the inspection system 300c to determine whether or not baggage of a predetermined size or larger contains a predetermined object, without exception, for all baggage. By displaying baggage of a predetermined size or larger that has not yet been subjected to the judgment on the display device 1104, it becomes possible to encourage the judgment to be carried out.

[0162] Furthermore, by denying entry to entrants who do not obtain a fourth judgment result for at least one piece of baggage, it is possible to prevent entrants from bringing in baggage that has not been judged to contain specified items and that is larger than a specified size.

[0163] Fifth embodiment Next, a fifth embodiment will be described. Among the configurations of the fifth embodiment, the description of the configurations similar to those of the first embodiment will be omitted or simplified by incorporating the description of the first embodiment.

[0164] Fig. 24 is a diagram showing a schematic configuration of an entrance management system 10d according to the fifth embodiment. In Fig. 24, some of the same components as those in the entrance management system 10 according to the first embodiment are omitted.

[0165] The baggage determination device 11d provided in the entrance management system 10d according to the fifth embodiment includes, for example, a fourth sensor 1120. The fourth sensor 1120 may be similar to the first sensor 1203. The fourth sensor 1120 is composed of, for example, a camera that captures visible light or infrared light, a LiDAR, a ToF sensor, a 3D sensor, etc. The fourth sensor 1120 may be composed of multiple sensors of the same type, like the first sensor 1203, or may be composed of a combination of multiple different types of sensors, such as a camera and a LiDAR, or a camera and a 3D sensor.

[0166] The fourth sensor 1120 may be installed, for example, in front of, behind, or above the user of the baggage determination device 11d, and may acquire information on the baggage carried by the user of the baggage determination device 11d. The fourth sensor 1120 may also be installed inside the first determination unit 1103, and may acquire information on the baggage determined by the first determination unit. The fourth sensor 1120 captures an image of the baggage carried by the user of the baggage determination device 11d. The fourth sensor 1120 outputs the captured image to the processing unit 1101, and is controlled by the processing unit 1101.

[0167] The processing unit 1101 of the baggage determination device 11d stores in the storage device 1001 information on baggage of a predetermined size or larger carried by the first ID holder, acquired by the fourth sensor 1120, in association with the first ID.

[0168] The entrance management device 12d according to the fifth embodiment includes, for example, a fifth determination unit 1220. The fifth determination unit 1220 may be the same as, for example, the second determination unit 1204. The fifth determination unit 1220 is, for example, an integrated circuit such as a CPU, a GPU, an FPGA, or a microcontroller. Alternatively, the fifth determination unit 1220 may be a computer such as a server incorporating a CPU, a GPU, or the like. The fifth determination unit 1220 includes a program executed by the integrated circuit such as the CPU.

[0169] Based on the information acquired by the fourth sensor 1120, the fifth determination unit 1220 determines whether all baggage of a predetermined size or more possessed by the second ID holder is baggage that has already been determined by the baggage determination device 11e. Specifically, the fifth determination unit 1220 determines whether all baggage of a predetermined size or more possessed by the second ID holder is associated with the first ID corresponding to the second ID and stored in the storage device 1001. For example, it is assumed that at least one of the baggage of a predetermined size or more possessed by the second ID holder is not associated with the first ID corresponding to the second ID and stored in the storage device 1001, that is, the second ID holder is possessing baggage of a predetermined size or more that was not possessed when the baggage determination device 11d was used. In this case, the processing unit 1201 outputs information that entry is not permitted. On the other hand, since the fifth determination unit does not determine baggage of a size smaller than the predetermined size, even if the second ID holder purchases, for example, food and drink after the determination by the baggage determination device 11d, the second ID holder can enter without re-determination by the baggage determination device 11d, which improves the inspection throughput of the inspection system 300d. It is also possible to prevent unauthorized entry by a second ID holder who, after having been identified by baggage identification device 11d, receives baggage from a third party that is equal to or larger than a predetermined size and has not yet been identified by baggage identification device 11d.

[0170] FIG. 25 is a plan view showing an outline of an inspection system 300d to which an entrance management system 10d according to the fifth embodiment is applied.

[0171] In an inspection system 300d according to the fifth embodiment shown in FIG. 25, the baggage determination device 11da includes a fourth sensor 1120a, the baggage determination device 11db includes a fourth sensor 1120b, and the baggage determination device 11dc includes a fourth sensor 1120c.

[0172] The first determination routine in the entrance management system 10d according to the fifth embodiment will be described with reference to the flowchart shown in FIG.

[0173] The first ID recognition unit 1102 acquires information on the first ID held by the first ID holder (S501).

[0174] The processing unit 1101 determines whether the information of the first ID has been acquired (S502). If the first ID information has not been acquired (S502: NO), the processing unit 1101 ends the first determination routine.

[0175] If the information of the first ID can be acquired (S502: YES), the processing unit 1101 judges whether the first ID is qualified to enter (S503). If the first ID is not qualified to enter (S503: NO), the processing unit 1101 ends the first judgment routine.

[0176] If the first ID is eligible for entry (S503: YES), the processing unit 1101 starts a baggage determination loop (S504). The first ID holder places the baggage in the baggage determination device 11 (S505). The fourth sensor 1120 acquires information on the baggage held by the first ID holder (S506). The processing unit 1101 associates the first ID with the information on the baggage acquired by the fourth sensor 1120 and stores it in the storage device 1001 (S507). The first determination unit 1103 judges whether the baggage includes a predetermined object (S508). The processing unit 1101 associates the first judgment result with the first ID and stores it in the storage device 1001 (S509). The processing unit 1101 judges whether the first ID holder has finished the baggage determination loop (S510). If the first ID holder has finished the baggage determination loop (S510: YES), the processing unit 1101 ends the baggage determination loop (S511) and ends the first determination routine. If the first ID holder has not finished the baggage determination loop (S510: NO), the processing unit 1101 repeats the baggage determination loop.

[0177] Next, the entry permission / prohibition judgment routine in the entry management system 10d according to the fifth embodiment will be described with reference to the flowcharts shown in Figs. 27A and 27B.

[0178] Of the entry permission determination routine according to the fifth embodiment, steps S520 to S527 correspond to steps S110 to S117 of the entry permission determination routine according to the first embodiment shown in FIG. 6, and therefore will be omitted.

[0179] When the first judgment result associated with the first ID corresponding to the second ID can be acquired (S526: YES), the processing unit 1201 acquires information on the baggage carried by the second ID holder via the first sensor 1203 (S528). The processing unit 1201 acquires information on the baggage associated with the first ID corresponding to the second ID from the storage device 1001 (S529). The fifth judgment unit 1220 judges whether all baggage of a predetermined size or more carried by the second ID holder is associated with the first ID corresponding to the second ID (S530). When at least one baggage of the predetermined size or more is not associated with the first ID corresponding to the second ID (S530: NO), the processing unit 1201 outputs information indicating that entry is not permitted (S531) and ends the entry permission judgment routine. If all of the baggage larger than the specified size is linked to the first ID corresponding to the second ID (S530: YES), the processing unit 1201 executes the specified item determination subroutine for the baggage of the second ID holder shown in Figure 8 (S532) and terminates the entry permission determination routine.

[0180] As described above, according to the entrance management system 10d of the fifth embodiment, in the inspection system 300d to which the entrance management system 10d is applied, if at least one piece of baggage of a predetermined size or more is not associated with the first ID corresponding to the second ID and stored in the storage device 1001, that is, if an entrance is carrying baggage of a predetermined size or more that was not carried when the baggage determination device 11d was used, the entrance is denied, thereby making it possible to prevent unauthorized entry by receiving baggage from a third party after the determination by the baggage determination device 11d. On the other hand, since baggage smaller than the predetermined size is not determined by the fifth determination unit, even if the second ID holder purchases, for example, food and drink after the determination by the baggage determination device 11d, the entrance is possible without re-determination by the baggage determination device 11d, and therefore the inspection throughput of the inspection system 300d can be improved.

[0181] Sixth embodiment Next, a sixth embodiment will be described.

[0182] Among the configurations of the sixth embodiment, the description of the configurations similar to those of the first embodiment will be omitted or simplified by incorporating the description of the first embodiment.

[0183] Fig. 28 is a diagram showing a schematic configuration of an entrance management system 10e according to a sixth embodiment. Fig. 29 is a plan view showing a schematic configuration of an inspection system 300d to which the entrance management system 10e according to the sixth embodiment is applied. In Fig. 28, some of the same components as those in the entrance management system 10 according to the first embodiment are omitted.

[0184] A baggage determination device 11e provided in an entrance control system 10e according to the sixth embodiment includes, for example, a tag issuing unit 16e.

[0185] In an inspection system 300e according to the sixth embodiment shown in FIG. 29, the baggage determination device 11ea includes a tag issuing unit 16ea, the baggage determination device 11eb includes a tag issuing unit 16eb, and the baggage determination device 11ec includes a tag issuing unit 16ec.

[0186] The tag issue unit 16e includes, for example, a processing unit 1601, a tag printing unit 1602, a tag storage unit 1603, and a tag receiving unit 1604.

[0187] The processing unit 1601 receives information from the processing unit 1101 of the baggage determination device 11e, and transmits information to the processing unit 1101. The processing unit 1601 may, for example, read and write stored information in the storage device 1001 via the processing unit 1101, or obtain first ID information obtained by the first ID recognition unit 1102. The processing unit 1601 writes the obtained first ID information to a tag. The processing unit 1601 also links the tag issued by the tag issue unit 16e with the first ID and transmits it to the processing unit 1101. The processing unit 1601 also controls the tag issuance process.

[0188] The tag printing unit 1602 prints tags under the control of the processing unit 1601. The tag storage unit 1603 has a function of storing tags to be printed by the tag printing unit 1602. The tag receiving unit 1604 is configured so that a user of the baggage determination device 11e can send the tag printed by the tag printing unit 1602 and receive the tag.

[0189] The tag printing unit 1602 acquires a tag from the tag storage unit 1603 and sends the printed tag to the tag receiving unit 1604. The tag printing unit 1602 may print information on the tag using ink, or, when the tag is an RFID (Radio Frequency Identification) tag, may read and write information on an IC provided in the RFID tag.

[0190] 30 shows an example of a tag 1610 issued by the tag issuing unit 16e. The tag 1610 includes, for example, information 16101 about a first ID holder and a tag ID 16102.

[0191] The information 16101 of the first ID holder may be, for example, the same as the display content 11042 shown in Fig. 3A. The information 16101 of the first ID holder may be, for example, a name, age, gender, etc., that are linked in advance to the first ID. Furthermore, for example, when inspecting visitors to a movie theater or concert venue, or passengers on a train or bus, the information 16101 of the first ID holder may be a seat, an available time of entry, a train or bus destination, etc., that are linked in advance to the ID. The information 16101 of the first ID holder is not limited to text, and may be, for example, an image such as a face photo of the first ID holder linked to the first ID.

[0192] The tag ID 16102 is a unique identification code given to a tag issued by the tag issuing unit 16e. When the tag issuing unit 16e issues multiple tags 1610, a different ID is given to each tag, and the tag is identified based on the ID 16102. The ID 16102 may be printed and displayed on the tag 1610, or may be electronically recorded in the IC 16103. The ID 16102 may be displayed as a character string, or may be displayed as an identifier such as a one-dimensional or two-dimensional code.

[0193] The tag 1610 may include, for example, an IC 16103 and an antenna 16104. In this case, the tag 1610 operates as an RFID tag capable of reading and writing information recorded in the IC 16103 by electromagnetic means. If the tag 1610 is an RFID tag, the fifth sensor 1230 can read the tag held by the second ID holder in a non-contact manner.

[0194] In the inspection system 300e according to the sixth embodiment shown in Fig. 29, the second entrance 301a includes a fifth sensor 1230a, the second entrance 301b includes a fifth sensor 1230b, and the second entrance 301c includes a fifth sensor 1230c. The fifth sensor 1230a acquires information on a tag carried by a passerby at the second entrance 301a. The same is true for the fifth sensors 1230b and 1230c.

[0195] The sixth determination unit 1231 is, for example, an integrated circuit such as a CPU, a GPU, an FPGA, or a microcontroller. Alternatively, the sixth determination unit 1231 may be a computer such as a server incorporating a CPU or a GPU. The sixth determination unit 1231 includes a program executed by the integrated circuit such as the CPU.

[0196] The sixth determination unit 1231 determines whether all baggage of a predetermined size or more held by the second ID holder is baggage that has already been determined by the baggage determination device 11e, based on the information acquired by the first sensor 1203 and the fifth sensor 1230. Specifically, the sixth determination unit 1231 determines whether the number of pieces of baggage of a predetermined size or more determined by the second determination unit 1204 matches, based on the information of the tag held by the second ID holder acquired by the fifth sensor 1230 and the information acquired by the first sensor 1203. The sixth determination unit 1231 also determines whether the information of the tag held by the second ID holder acquired by the fifth sensor 1230 matches the information of the tag stored in the baggage determination device 11e in association with the first ID corresponding to the second ID.

[0197] When the sixth determination unit 1231 determines that the number of tags held by the second ID holder does not match the number of tags stored in association with the first ID corresponding to the second ID, the processing unit 1201 outputs information that the second ID holder is not allowed to enter. Even if the number of tags held by the second ID holder matches the number of tags stored in association with the first ID corresponding to the second ID, if the number of tags does not match the tag information stored in association with the first ID corresponding to the second ID in the baggage determination device 11e, the processing unit 1201 outputs information that the second ID holder is not allowed to enter. In this way, it is possible to prevent the second ID holder from receiving baggage that has not been determined to contain a specified object after using the baggage determination device and illegally entering the facility.

[0198] The first determination routine in the entrance management system 10e according to the sixth embodiment will be described with reference to the flowchart shown in FIG.

[0199] The first ID recognition unit 1102 acquires information on the first ID held by the first ID holder (S601).

[0200] The processing unit 1101 determines whether the information of the first ID has been acquired (S602). If the first ID information has not been acquired (S602: NO), the processing unit 1101 ends the first determination routine.

[0201] If the information of the first ID can be acquired (S602: YES), the processing unit 1101 judges whether the first ID is qualified to enter (S603). If the first ID is not qualified to enter (S603: NO), the processing unit 1101 ends the first judgment routine.

[0202] If the first ID is eligible for entry (S603: YES), the processing unit 1101 starts a baggage determination loop (S604). The first ID holder places the baggage in the baggage determination device 11 (S605). The processing unit 1101 determines whether the baggage includes a predetermined object in the first determination unit (S606). The processing unit 1101 associates the first ID with the first determination result and stores it in the storage device 1001 (S607). The tag issuing unit 16e issues a tag corresponding to the baggage (S608). The processing unit 1601 associates the tag with the first ID and stores it in the storage device 1001 via the processing unit 1101 (S609). The processing unit 1101 determines whether the first ID holder has finished the baggage determination loop (S610). If the processing unit 1101 determines that the first ID holder has completed the baggage determination loop (S610: YES), it ends the baggage determination loop (S611) and ends the first determination routine. If the processing unit 1101 determines that the first ID holder has not completed the baggage determination loop (S610: NO), it repeats the baggage determination loop.

[0203] Next, the admission permission determination routine in the admission management system 10e according to the sixth embodiment will be described with reference to the flowcharts shown in FIGS. 32A and 32B.

[0204] Of the entry permission determination routine according to the sixth embodiment, steps S620 to S627 correspond to steps S110 to S117 of the entry permission determination routine according to the first embodiment shown in FIG. 6, and therefore will be omitted.

[0205] When the first judgment result associated with the first ID corresponding to the second ID can be acquired (S626: YES), the processing unit 1201 acquires information on the baggage carried by the second ID holder via the first sensor 1203 (S628). The fifth sensor 1230 acquires information on the tag carried by the second ID holder (S629). The sixth judgment unit 1231 judges whether the number of all pieces of baggage of a predetermined size or more carried by the second ID holder matches the number of tags carried by the second ID based on the first sensor information and the fifth sensor information (S630). When the number of all pieces of baggage of a predetermined size or more carried by the second ID holder does not match the number of tags carried by the second ID (S631: NO), the processing unit 1201 outputs information that entry is not permitted (S632) and ends the entry permission judgment routine.

[0206] If the number of all pieces of baggage of a predetermined size or more held by the second ID holder matches the number of tags held by the second ID (S631: NO), the sixth determination unit 1231 determines whether the tag information acquired by the fifth sensor matches the tag information linked to the first ID corresponding to the second ID (S633). When the sixth determination unit 1231 determines that at least one piece of tag information acquired by the fifth sensor 1230 does not match the tag information linked to the first ID corresponding to the second ID (S634: NO), the processing unit 1201 outputs information that entry is not permitted (S635) and ends the entry permission determination routine. When the sixth judgment unit 1231 determines that the tag information acquired by the fifth sensor 1230 matches all the tag information linked to the first ID corresponding to the second ID (S634: YES), the processing unit 1201 executes the specified item judgment subroutine for the baggage of the second ID holder shown in Figure 8A (S636).

[0207] As described above, according to the entrance management system 10e of the sixth embodiment, by issuing tags corresponding to baggage of a specified size or larger in the baggage determination device 11e, it is possible to prevent a second ID holder from receiving baggage that has not been determined to contain a specified item after using the baggage determination device and gaining unauthorized entry.

[0208] In the above embodiments, examples have been shown in which the baggage determination device 11, entrance management device 12, passage section 13, body determination device 14, and gate device 15 each perform various information processing using their own processing units 1101, 1201, 1301, 1401, and 1501. However, the entrance management system 10 may also be configured such that a server connected to each of the baggage determination device 11, entrance management device 12, passage section 13, body determination device 14, and gate device 15 via a network receives information from each device and centrally performs various information processing.

[0209] The present invention is not limited to the above-described embodiment, and the components can be modified and embodied in the implementation stage without departing from the gist of the invention. In addition, various inventions can be formed by appropriately combining the multiple components disclosed in the above-described embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, components from different embodiments may be appropriately combined.
