[0009] Hereinafter, embodiments of an entrance management system, an entrance management method, and a recording medium will be described with reference to the drawings.

[0010] (1) First embodiment First, a first embodiment of the entrance management system, entrance management method, and recording medium will be described. Below, the first embodiment of the entrance management system, entrance management method, and recording medium will be described using an entrance management system 1000 to which the first embodiment of the entrance management system, entrance management method, and recording medium is applied, with reference to Figure 1. Figure 1 is a block diagram showing the configuration of the entrance management system 1000 in the first embodiment.

[0011] The entrance management system 1000 manages the entry of a target person who enters the entrance restricted area by boarding a target vehicle. In order to manage the entry of a target person into the entrance restricted area, the entrance management system 1000 includes a memory unit 1100, a first imaging unit 1200, a first determination unit 1300, a second imaging unit 1400, a second determination unit 1500, and an entrance management unit 1600.

[0012] The storage unit 1100 stores registration information 1110. The registration information 1110 is information in which vehicle information 1111 and person information 1112 are associated with each other. The vehicle information 1111 indicates the vehicle number of a registered vehicle scheduled to enter the entry-restricted area. The person information 1112 includes a registered image of a registered person scheduled to enter the entry-restricted area in a registered vehicle.

[0013] The first imaging unit 1200 generates a vehicle image by capturing an image of a target vehicle located at a vehicle entrance through which the target vehicle must pass to enter the restricted entry area. The first determination unit 1300 determines whether the target vehicle located at the vehicle entrance is a registered vehicle by comparing the vehicle number of the target vehicle captured in the vehicle image with the vehicle number of a registered vehicle indicated in the vehicle information.

[0014] The second imaging unit 1400 generates a person image by capturing an image of a target person riding in a target vehicle located at the vehicle entrance. The second determination unit 1500 compares the person image with a registered image indicated by the person information to determine whether the target person riding in the target vehicle is a registered person.

[0015] The entrance management unit 1600 permits the target vehicle to pass through the vehicle entrance when the first determination unit 1300 determines that the target vehicle located at the vehicle entrance is a registered vehicle and the second determination unit 1500 determines that the target person riding in the target vehicle is a registered person. On the other hand, the entrance management unit 1600 does not permit the target vehicle to pass through the vehicle entrance when the first determination unit 1300 determines that the target vehicle located at the vehicle entrance is not a registered vehicle. Furthermore, the entrance management unit 1600 does not permit the target vehicle to pass through the vehicle entrance when the second determination unit 1500 determines that the target person riding in the target vehicle is not a registered person.

[0016] The above-described entrance management system 1000 determines whether to permit a vehicle to pass through the vehicle entrance using the vehicle image captured by the first imaging unit 1200, the person image captured by the second imaging unit 1400, and the registration information pre-stored in the storage unit 1100. This eliminates the need for the target person to exit the target vehicle at the vehicle entrance and fill out necessary documents to enter the restricted entry area. This allows the target person to enter the restricted entry area while remaining in the target vehicle. This reduces the time required to enter the restricted entry area. As a result, the possibility of a large number of target vehicles wishing to enter the restricted entry area accumulating at the vehicle entrance (resulting in traffic congestion) is reduced. Therefore, the entrance management system 1000 can solve the technical problem of a large number of target vehicles wishing to enter the restricted entry area accumulating at the vehicle entrance.

[0017] Furthermore, the entrance management system 1000 allows the target vehicle to pass through the vehicle entrance when the target vehicle is determined to be a registered vehicle and the target person is determined to be a registered person. Therefore, compared to a case in which the target vehicle is allowed to pass through the vehicle entrance even when the target vehicle is determined to be a registered vehicle but the target person is not determined to be a registered person, the entrance management system 1000 can more appropriately prevent suspicious target persons from entering the restricted entry area. Similarly, compared to a case in which the target vehicle is allowed to pass through the vehicle entrance even when the target person is determined to be a registered person but the target vehicle is not determined to be a registered vehicle, the entrance management system 1000 can more appropriately prevent suspicious target persons from entering the restricted entry area. Therefore, the entrance management system 1000 can solve the technical problem of the possibility of suspicious target persons entering the restricted entry area.

[0018] (2) Second embodiment Next, a second embodiment of the entrance management system, the entrance management method, and the recording medium will be described. Below, the second embodiment of the entrance management system, the entrance management method, and the recording medium will be described using the entrance management system SYS to which the second embodiment of the entrance management system, the entrance management method, and the recording medium is applied.

[0019] The admission control system SYS manages the entry of a target person P who gets into the admission restricted area 9 by getting into a target vehicle V. Furthermore, the admission control system SYS may monitor the behavior of the target person P who has entered the admission restricted area 9 within the admission restricted area 9. Furthermore, the admission control system SYS may manage the exit of the target person P who has entered the admission restricted area 9 from the admission restricted area 9.

[0020] In the second embodiment, an example will be described in which the entry-restricted area 9 is a factory. In this case, the entrance management system SYS may manage the entry of a target person P who enters the factory in a target vehicle V. Furthermore, the entrance management system SYS may manage the behavior of the target person P within the factory after entering the factory. Furthermore, the entrance management system SYS may manage the exit of the target person P from the factory after entering the factory.

[0021] However, the restricted entry area 9 is not limited to a factory. The restricted entry area 9 may be any area as long as it is an area where free entry of target persons is restricted. For example, other examples of the restricted entry area 9 include at least one of a corporate office, a school, a theme park, and an airport.

[0022] The following is an explanation of this admission management system SYS.

[0023] (2-1) Configuration of the admission management system SYS First, the configuration of the admission control system SYS in the second embodiment will be described.

[0024] (2-1-1) Overall configuration of the admission management system SYS First, the overall configuration of the entrance management system SYS in the second embodiment will be described with reference to Figures 2 and 3. Figure 2 is a block diagram showing the overall configuration of the entrance management system SYS in the second embodiment. Figure 3 is a layout of the entrance restricted area 9 into which the target person P enters.

[0025] 2 and 3, the entrance control system SYS comprises a vehicle gate device 1, a user terminal 2, a person gate device 3, a surveillance camera 4 which is a specific example of the "fourth imaging means" described in the appendix below, and an entrance control server 5. In the example shown in FIG. 2, the entrance control system SYS comprises multiple user terminals 2, but may also comprise a single user terminal 2. Furthermore, in the example shown in FIG. 2, the entrance control system SYS comprises multiple surveillance cameras 4, but may also comprise a single surveillance camera 4.

[0026] As shown in FIG. 3 , the vehicle gate device 1 is disposed at a vehicle entrance 91 through which a target vehicle V must pass to enter the entry restricted area 9. The target vehicle V enters the entry restricted area 9 (particularly, a first restricted area 9A within the entry restricted area 9) from an area outside the entry restricted area 9 through the vehicle entrance 91. The vehicle gate device 1 captures an image of the target vehicle V positioned at the vehicle entrance 91 to enter the entry restricted area 9, thereby generating a vehicle image IMG_V in which the target vehicle V is captured. The vehicle gate device 1 transmits the generated vehicle image IMG_V to the entrance management server 5.

[0027] The vehicle entrance 91 may be used as a vehicle exit through which the target vehicle V must pass to exit the entry restricted area 9. The target vehicle V may exit from the entry restricted area 9 to an area outside the entry restricted area 9 through the vehicle entrance 91. The vehicle gate device 1 may capture an image of the target vehicle V located at the vehicle entrance 91 to exit the entry restricted area 9, thereby generating a vehicle image IMG_V in which the target vehicle V is captured.

[0028] However, the vehicle entrance 91 does not have to be used as a vehicle exit gate through which the target vehicle V must pass to exit the entry restricted area 9. The entry restricted area 9 may be provided with a vehicle exit gate through which the target vehicle V must pass to exit the entry restricted area 9, separate from the vehicle entrance 91. In this case, the vehicle exit gate may be equipped with the vehicle gate device 1 described above. In the following explanation, an example will be described in which the vehicle entrance 91 is used as a vehicle exit gate through which the target vehicle V must pass to exit the entry restricted area 9.

[0029] The user terminal 2 is an information terminal (e.g., a smartphone or a tablet terminal) owned by a target person P who will enter the entry-restricted area 9. Therefore, the entrance management system SYS may include the same number of user terminals 2 as the number of target persons P who will enter the entry-restricted area 9. However, one user terminal 2 may be shared by two or more target persons P. The user terminal 2 generates a person image IMG_P1 in which the target person P appears by capturing an image of the target person P riding in a target vehicle V located at the vehicle entrance 91. For example, the user terminal 2 may generate the person image IMG_P1 by capturing an image of the target person P riding in the target vehicle V that is about to enter the entry-restricted area 9 through the vehicle entrance 91. For example, the user terminal 2 may generate the person image IMG_P1 by capturing an image of the target person P riding in the target vehicle V that is about to exit the entry-restricted area 9 through the vehicle entrance 91. The user terminal 2 transmits the generated person image IMG_P1 to the entrance management server 5.

[0030] As shown in FIG. 3 , the person gate device 3 is disposed at a person entrance 92 within the entry-restricted area 9. A target vehicle V that has passed through the vehicle entrance 91 is parked in a parking lot 93 within the entry-restricted area 9 (particularly, within the first restricted area 9A). A target person P passes through the person entrance 92 after getting out of the target vehicle V. The target person P enters the second restricted area 9B within the entry-restricted area 9 from the first restricted area 9A within the entry-restricted area 9 through the person entrance 92. In this case, the person entrance 92 may be considered to be the person entrance through which the target person P must pass to enter the second restricted area 9B. The person gate device 3 captures an image of the target person P positioned at the person entrance 92 to enter the second restricted area 9B, thereby generating a person image IMG_P2 in which the target person P is captured. The person gate device 3 transmits the generated person image IMG_P2 to the entrance management server 5.

[0031] The person entrance 92 may be used as a person exit entrance through which the target person P must pass to exit from the second restricted area 9B. The target person P may exit from the second restricted area 9B to the first restricted area 9A through the person entrance 92. The person gate device 3 may generate a person image IMG_P2 in which the target person P is captured by capturing an image of the target person P positioned at the person entrance 92 to exit from the second restricted area 9B.

[0032] However, the person entrance 92 does not have to be used as a person exit gate through which the target person P must pass to exit from the second restricted area 9B. In the entry restricted area 9, a person exit gate through which the target person P must pass to exit from the second restricted area 9B may be arranged separately from the person entrance 92. In this case, the person exit gate may be equipped with the above-mentioned person gate device 3. In the following explanation, an example will be described in which the person entrance 92 is used as a person exit gate through which the target person P must pass to exit from the second restricted area 9B.

[0033] The surveillance cameras 4 are placed within the restricted entry area 9. In the example shown in FIG. 3, each of the multiple surveillance cameras 4 is placed in a second restricted area 9B within the restricted entry area 9 (i.e., an area into which a target person P who has passed through the person entrance 92 enters). However, at least one of the multiple surveillance cameras 4 may be placed in a first restricted area 9A within the restricted entry area 9 (i.e., an area into which a target person P who has passed through the vehicle entrance 91 but has not yet passed through the person entrance 92 enters). The surveillance camera 4 captures an image of its imaging range 41, thereby generating a surveillance image IMG_M that captures the scene within the imaging range 41. The surveillance camera 4 transmits the generated surveillance image IMG_M to the entrance management server 5.

[0034] The entrance management server 5 performs a vehicle entry management operation for managing the entry of a target vehicle V into the entry-restricted area 9 (particularly, the first restricted area 9A) via the vehicle entrance 91. To perform the vehicle entry management operation, the entrance management server 5 acquires a vehicle image IMG_V from the vehicle gate device 1 and acquires a person image IMG_P1 from the user terminal 2. Based on the vehicle image IMG_V, the entrance management server 5 determines whether the target vehicle V located at the vehicle entrance 91 is a registered vehicle V_R scheduled to enter the entry-restricted area 9. Furthermore, based on the person image IMG_P1, the entrance management server 5 determines whether the target person P riding in the target vehicle V is a registered person P_R scheduled to enter the entry-restricted area 9. If it is determined that the target vehicle V is a registered vehicle V_R and that the target person P is a registered person P_R, the entrance management server 5 permits the target vehicle V to pass through the vehicle entrance 91. In other words, the entrance management server 5 permits the target vehicle V and the target person P riding in the target vehicle V to enter the entry restricted area 9 (particularly, the first restricted area 9A) through the vehicle entrance 91. On the other hand, if it is determined that the target vehicle V is not a registered vehicle V_R, the entrance management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. Also, if it is determined that the target person P is not a registered person P_R, the entrance management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. In other words, the entrance management server 5 does not permit the target vehicle V and the target person P riding in the target vehicle V to enter the entry restricted area 9 (particularly, the first restricted area 9A) through the vehicle entrance 91.

[0035] Furthermore, the admission management server 5 performs a person admission management operation to manage the entry of a target person P into the second restricted area 9B through the person entrance 92. To perform the person admission management operation, the admission management server 5 acquires a person image IMG_P2 from the person gate device 3. Based on the person image IMG_P2, the admission management server 5 determines whether the target person P located at the person entrance 92 is a registered person P_R who is scheduled to enter the admission restricted area 9. If it is determined that the target person P is a registered person P_R, the admission management server 5 permits the target person P to pass through the person entrance 92. That is, the admission management server 5 permits the target person P to enter the second restricted area 9B through the person entrance 92. On the other hand, if it is determined that the target person P is not a registered person P_R, the admission management server 5 does not permit the target person P to pass through the person entrance 92. That is, the admission management server 5 does not permit the target person P to enter the second restricted area 9B through the person entrance 92.

[0036] Furthermore, the entrance management server 5 performs a monitoring operation to monitor at least one of the target vehicle V and the target person P located within the entry restricted area 9. To perform the monitoring operation, the entrance management server 5 acquires a monitoring image IMG_M from the monitoring camera 4. The entrance management server 5 monitors at least one of the target vehicle V and the target person P located within the entry restricted area 9 based on the monitoring image IMG_M.

[0037] Furthermore, the admission management server 5 performs a person exit management operation to manage the exit of the target person P from the second restricted area 9B through the person entrance 92. To perform the person exit management operation, the admission management server 5 acquires a person image IMG_P2 from the person gate device 3. Based on the person image IMG_P2, the admission management server 5 determines whether the target person P located at the person entrance 92 is a registered person P_R. If it is determined that the target person P is a registered person P_R, the admission management server 5 permits the target person P to pass through the person entrance 92. That is, the admission management server 5 permits the target person P to exit from the second restricted area 9B through the person entrance 92. On the other hand, if it is determined that the target person P is not a registered person P_R, the admission management server 5 does not permit the target person P to pass through the person entrance 92. That is, the admission management server 5 does not permit the target person P to exit from the second restricted area 9B through the person entrance 92.

[0038] Furthermore, the entrance management server 5 performs a vehicle exit management operation for managing the exit of the target vehicle V from the entry restricted area 9 (particularly, the first restricted area 9A) via the vehicle entrance 91. To perform the vehicle exit management operation, the entrance management server 5 acquires a vehicle image IMG_V from the vehicle gate device 1 and acquires a person image IMG_P1 from the user terminal 2. Based on the vehicle image IMG_V, the entrance management server 5 determines whether the target vehicle V located at the vehicle entrance 91 is a registered vehicle V_R. Based on the person image IMG_P1, the entrance management server 5 also determines whether the target person P riding in the target vehicle V is a registered person P_R. If the target vehicle V is determined to be a registered vehicle V_R and the target person P is determined to be a registered person P_R, the entrance management server 5 allows the target vehicle V to pass through the vehicle entrance 91. In other words, the admission management server 5 permits the target vehicle V and the target person P riding in the target vehicle V to exit the admission restricted area 9 (particularly, the first restricted area 9A) through the vehicle entrance 91. On the other hand, if it is determined that the target vehicle V is not a registered vehicle V_R, the admission management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. Also, if it is determined that the target person P is not a registered person P_R, the admission management server 5 does not permit the target vehicle V to pass through the vehicle entrance 91. In other words, the admission management server 5 does not permit the target vehicle V and the target person P riding in the target vehicle V to exit the admission restricted area 9 (particularly, the first restricted area 9A) through the vehicle entrance 91.

[0039] (2-1-2) Configuration of vehicle gate device 1 Next, the configuration of the vehicle gate device 1 will be described with reference to Fig. 4. Fig. 4 is a block diagram showing the configuration of the vehicle gate device 1.

[0040] As shown in FIG. 4, the vehicle gate device 1 includes a vehicle gate mechanism 11, a vehicle camera 12 which is a specific example of a "first imaging means" described in the appendix below, and a communication device 13.

[0041] The vehicle gate mechanism 11 is a device capable of controlling the passage of a target vehicle V through the vehicle entrance 91. The state of the vehicle gate mechanism 11 is controlled based on a vehicle gate control signal transmitted from the entrance management server 5. In the second embodiment, the state of the vehicle gate mechanism 11 is switchable between a closed state in which the target vehicle V cannot pass through the vehicle entrance 91 and an open state in which the target vehicle V can pass through the vehicle entrance 91. For example, if the vehicle gate mechanism 11 is equipped with a gate bar, the state of the vehicle gate mechanism 11 may be switchable between a closed state in which the gate bar is closed and an open state in which the gate bar is open.

[0042] The vehicle camera 12 captures an image of a target vehicle V located at the vehicle entrance 91, thereby generating a vehicle image IMG_V that captures the target vehicle V. The vehicle camera 12 transmits the generated vehicle image IMG_V to the entrance management server 5.

[0043] The communication device 13 is capable of communicating with the entrance management server 5 via a communication network (not shown). In the second embodiment, the communication device 13 transmits the vehicle image IMG_V captured by the vehicle camera 12 to the entrance management server 5. That is, the vehicle camera 12 transmits the vehicle image IMG_V to the entrance management server 5 using the communication device 13. Furthermore, in the second embodiment, the communication device 13 receives a vehicle gate control signal from the entrance management server 5. The state of the vehicle gate mechanism 11 is controlled based on the vehicle gate control signal received by the communication device 13.

[0044] (2-1-3) Configuration of User Terminal 2 Next, the configuration of the user terminal 2 will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the configuration of the user terminal 2.

[0045] 5, the user terminal 2 includes a camera 20, which is a specific example of the "second imaging means" described in the appendix below, a calculation device 21, a storage device 22, and a communication device 23. The user terminal 2 may further include an input device 24 and an output device 25. However, the user terminal 2 does not necessarily have to include at least one of the input device 24 and the output device 25. The camera 20, the calculation device 21, the storage device 22, the communication device 23, the input device 24, and the output device 25 may be connected via a data bus 26.

[0046] The camera 20 generates a person image IMG_P1 by capturing an image of the target person P. In particular, as described above, the camera 20 generates the person image IMG_P1 by capturing an image of the target person P riding in the target vehicle V located at the vehicle entrance 91. The camera 20 transmits the generated person image IMG_P1 to the entrance management server 5.

[0047] The arithmetic device 21 includes, for example, at least one of a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), and an FPGA (Field Programmable Gate Array). The arithmetic device 21 reads a computer program. For example, the arithmetic device 21 may read a computer program stored in the storage device 22. For example, the arithmetic device 21 may read a computer program stored in a computer-readable, non-transitory recording medium using a recording medium reading device (not shown) provided in the user terminal 2. The arithmetic device 21 may acquire (i.e., download or read) the computer program from a device (not shown) located outside the user terminal 2 via the communication device 23 (or another communication device). The arithmetic device 21 executes the read computer program. As a result, logical functional blocks for performing operations to be performed by the user terminal 2 are realized within the arithmetic device 21. In other words, the arithmetic device 21 can function as a controller for realizing logical functional blocks for performing operations (in other words, processing) to be performed by the user terminal 2.

[0048] The storage device 22 can store desired data. For example, the storage device 22 may temporarily store a computer program executed by the arithmetic device 21. The storage device 22 may temporarily store data that the arithmetic device 21 temporarily uses when the arithmetic device 21 is executing a computer program. The storage device 22 may store data that the user terminal 2 stores long-term. In particular, in this embodiment, the storage device 22 may store an admission history DB 421. The storage device 22 may include at least one of a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, a magneto-optical disk device, an SSD (Solid State Drive), and a disk array device. In other words, the storage device 22 may include a non-temporary recording medium.

[0049] The communication device 23 is capable of communicating with the entrance management server 5 via a communication network (not shown). In the second embodiment, the communication device 23 transmits the person image IMG_P1 captured by the camera 20 to the entrance management server 5. That is, the camera 20 transmits the person image IMG_P1 to the entrance management server 5 using the communication device 23.

[0050] The input device 24 is a device that accepts information input to the user terminal 2 from outside the user terminal 2. For example, the input device 24 may include an operation device (for example, at least one of a keyboard, a mouse, and a touch panel) that can be operated by an operator of the user terminal 2. For example, the input device 24 may include a reading device that can read information recorded as data on a recording medium that can be externally attached to the user terminal 2.

[0051] The output device 25 is a device that outputs information to the outside of the user terminal 2. For example, the output device 25 may output information as an image. That is, the output device 25 may include a display device (a so-called display) that can display an image showing the information to be output. For example, the output device 25 may output information as sound. That is, the output device 25 may include an audio device (a so-called speaker) that can output sound. For example, the output device 25 may output information on paper. That is, the output device 25 may include a printing device (a so-called printer) that can print desired information on paper.

[0052] (2-1-4) Configuration of Person Gate Device 3 Next, the configuration of the person gate device 3 will be described with reference to Fig. 6. Fig. 6 is a block diagram showing the configuration of the person gate device 3.

[0053] As shown in FIG. 6, the person gate device 3 includes a person gate mechanism 31, a person camera 32 which is a specific example of the "third imaging means" described in the appendix below, and a communication device 33.

[0054] The person gate mechanism 31 is a device capable of controlling the passage of a target person P through the person entrance 92. The state of the person gate mechanism 31 is controlled based on a person gate control signal transmitted from the entrance management server 5. In the second embodiment, the state of the person gate mechanism 31 is switchable between a closed state in which the target person P cannot pass through the person entrance 92, and an open state in which the target person P can pass through the person entrance 92. For example, if the person gate mechanism 31 is equipped with a gate bar, the state of the person gate mechanism 31 may be switchable between a closed state in which the gate bar is closed, and an open state in which the gate bar is open.

[0055] The person camera 32 captures an image of a target person P positioned at the person entrance 92, and generates a person image IMG_P2 that includes the target person P. The person camera 32 transmits the generated person image IMG_P to the entrance management server 5.

[0056] The communication device 33 is capable of communicating with the entrance management server 5 via a communication network (not shown). In the second embodiment, the communication device 33 transmits the person image IMG_P2 captured by the person camera 32 to the entrance management server 5. That is, the person camera 32 transmits the person image IMG_P2 to the entrance management server 5 using the communication device 33. Furthermore, in the second embodiment, the communication device 33 receives a person gate control signal from the entrance management server 5. The state of the person gate mechanism 31 is controlled based on the person gate control signal received by the communication device 33.

[0057] (2-1-5) Configuration of admission management server 5 Next, the configuration of the entrance management server 5 will be described with reference to Fig. 7. Fig. 7 is a block diagram showing the configuration of the entrance management server 5.

[0058] 7, the entrance management server 5 includes a calculation device 51, a storage device 52, and a communication device 53. The entrance management server 5 may further include an input device 54 and an output device 55. However, the entrance management server 5 does not have to include at least one of the input device 54 and the output device 55. The calculation device 51, the storage device 52, the communication device 53, the input device 54, and the output device 55 may be connected via a data bus 56.

[0059] The arithmetic device 51 includes, for example, at least one of a CPU, a GPU, and an FPGA. The arithmetic device 51 loads a computer program. For example, the arithmetic device 51 may load a computer program stored in the storage device 52. For example, the arithmetic device 51 may load a computer program stored in a computer-readable, non-transitory storage medium using a storage medium reading device (not shown) included in the entrance management server 5. The arithmetic device 51 may acquire (i.e., download or load) the computer program from a device (not shown) located outside the entrance management server 5 via the communication device 53 (or another communication device). The arithmetic device 51 executes the loaded computer program. As a result, logical functional blocks for performing operations to be performed by the entrance management server 5 are realized within the arithmetic device 51. In other words, the arithmetic device 51 can function as a controller for realizing logical functional blocks for performing operations (in other words, processing) to be performed by the entrance management server 5.

[0060] As described above, in the second embodiment, the entrance management server 5 performs vehicle entrance management operations, person entrance management operations, monitoring operations, person exit operations, and vehicle exit operations. For this reason, logical function blocks for performing the vehicle entrance management operations, person entrance management operations, monitoring operations, person exit operations, and vehicle exit operations are realized within the computing device 51. Figure 7 shows an example of logical function blocks realized within the computing device 51 for performing the vehicle entrance management operations, person entrance management operations, monitoring operations, person exit operations, and vehicle exit operations. As shown in FIG. 7 , the computing device 51 includes a vehicle authentication unit 511, which is a specific example of a “first determination means” described in the appendix, a person authentication unit 512, which is a specific example of a “second determination means” and a “third determination means” described in the appendix, a vehicle gate control unit 513, which is a specific example of an “entrance management means” described in the appendix, a person gate control unit 514, which is a specific example of an “entrance management means” described in the appendix, and a monitoring unit 515, which is a specific example of a “fourth determination means” and a “warning means” described in the appendix. The vehicle authentication unit 511, the person authentication unit 512, and the vehicle gate control unit 513 are primarily used to perform vehicle entry management operations and vehicle exit management operations. The person authentication unit 512 and the person gate control unit 514 are primarily used to perform person entry management operations and person exit management operations. The monitoring unit 515 is primarily used to perform monitoring operations.

[0061] The storage device 52 can store desired data. For example, the storage device 52 may temporarily store a computer program executed by the arithmetic device 51. The storage device 52 may temporarily store data that the arithmetic device 51 temporarily uses when the arithmetic device 51 is executing a computer program. The storage device 52 may store data that the entrance management server 5 stores long-term. The storage device 52 may include at least one of RAM, ROM, a hard disk device, a magneto-optical disk device, an SSD, and a disk array device. In other words, the storage device 52 may include a non-temporary recording medium.

[0062] In particular, in the second embodiment, the storage device 52 may store a registration information DB (Database) 521 including information regarding registered vehicles V_R scheduled to enter the restricted entry area 9 and registered persons P_R scheduled to enter the restricted entry area 9.

[0063] 8(a) to 8(c) show examples of the data structure of the registration information DB 521. As shown in Fig. 8(a), the registration information DB 521 includes a plurality of registration information records 5210. Each registration information record 5210 includes a record ID 5211 for identifying the registration information record 5210, vehicle information 5212, and person information 5213. In other words, the registration information record 5210 is information in which the vehicle information 5212 and the person information 5213 are associated with each other by the record ID 5211.

[0064] The vehicle information 5212 is information about the registered vehicle V_R. Multiple registration information records 5210 may each include multiple pieces of vehicle information 5212 about multiple different registered vehicles V_R. An example of the data structure of the vehicle information 5212 is shown in FIG. 8(b). As shown in FIG. 8(b), the vehicle information 5212 may include vehicle number information about the vehicle number of the registered vehicle V_R (i.e., the vehicle number printed on the license plate). The vehicle information 5212 may include number of people information about the number of registered persons P_R who are scheduled to enter the restricted-entry area 9 in the registered vehicle V_R. The vehicle information 5212 may include administrator information about the administrator of the registered vehicle V_R. The administrator information may include information about the administrator's name, information about the administrator's affiliation, and information about the administrator's contact information. The vehicle information 5212 may also include vehicle permitted area information about vehicle entry permitted areas within the restricted-entry area 9 into which the registered vehicle V_R is permitted to enter.

[0065] The person information 5213 is information about a registered person P who is scheduled to enter the entry-restricted area 9 aboard a registered vehicle V_R corresponding to the vehicle information 5212. If only one registered person P is scheduled to enter the entry-restricted area 9 aboard a certain registered vehicle V_R, the person information 5213 may include information about that one registered person P_R. If only multiple registered persons P are scheduled to enter the entry-restricted area 9 aboard a certain registered vehicle V_R, the person information 5213 may include information about each of the multiple registered persons P_R.

[0066] An example of the data structure of the person information 5213 is shown in FIG. 8(c). As shown in FIG. 8(c), the person information 5213 may include a person ID for identifying the registered person P_R. The person information 5213 may include a registered image that is an image of the registered person P_R. The person information 5213 may include person permitted area information regarding a person entry permitted area within the entry restricted area 9 to which the registered person P_R is permitted to enter. The person information 5213 may include attendance information indicating whether the registered person P_R has taken safety training at a factory that is the entry restricted area 9. The attendance information may further include information regarding the date and time that the registered person P_R took the safety training.

[0067] The registration information record 5210 included in such a registration information DB 521 may be registered in advance by the administrator of the registered vehicle V_R or the registered person P_R. For example, the administrator of the registered vehicle V_R or the registered person P_R may transmit the vehicle information 5212 and the person information 5213 to the entrance management server 5 together with an application request to apply for entry into the entry-restricted area 9. The entrance management server 5 may newly register the registration information record 5210 including the vehicle information 5212 and the person information 5213 transmitted from the administrator of the registered vehicle V_R or the registered person P_R in the registration information DB 521.

[0068] 7 again, the communication device 53 is capable of communicating with the vehicle gate device 1, the user terminal 2, the person gate device 3, and the surveillance camera 4 via a communication network (not shown). In the second embodiment, the communication device 53 receives a vehicle image IMG_V from the vehicle gate device 1. Furthermore, the communication device 53 transmits a vehicle gate control signal to the vehicle gate device 1 for controlling the state of the vehicle gate mechanism 11. Furthermore, the communication device 53 receives a person image IMG_P1 from the user terminal 2. Furthermore, the communication device 53 receives a person image IMG_P2 from the person gate device 3. Furthermore, the communication device 53 transmits a person gate control signal to the person gate device 3 for controlling the state of the person gate mechanism 31. Furthermore, the communication device 53 receives a surveillance image IMG_M from the surveillance camera 4.

[0069] The input device 54 is a device that accepts information input to the admission management server 5 from outside the admission management server 5. For example, the input device 54 may include an operating device (for example, at least one of a keyboard, a mouse, and a touch panel) that can be operated by an operator of the admission management server 5. For example, the input device 54 may include a reading device that can read information recorded as data on a recording medium that can be externally attached to the admission management server 5.

[0070] The output device 55 is a device that outputs information to the outside of the entrance management server 5. For example, the output device 55 may output information as an image. That is, the output device 55 may include a display device (a so-called display) that can display an image showing the information to be output. For example, the output device 55 may output information as sound. That is, the output device 55 may include an audio device (a so-called speaker) that can output sound. For example, the output device 55 may output information on paper. That is, the output device 55 may include a printing device (a so-called printer) that can print desired information on paper.

[0071] (2-2) Operations performed by the admission management server 5 Next, we will explain the operations performed by the entrance management server 5. As described above, the entrance management server 5 performs vehicle entrance management operations, person entrance management operations, monitoring operations, person exit operations, and vehicle exit operations. Therefore, below we will explain the vehicle entrance management operations, person entrance management operations, monitoring operations, person exit operations, and vehicle exit operations in that order.

[0072] (2-2-1) Vehicle entry management operation First, the flow of the vehicle entry management operation will be described with reference to Fig. 9. Fig. 9 is a flowchart showing the flow of the vehicle entry management operation.

[0073] 9, the vehicle authentication unit 511 acquires a vehicle image IMG_V from the vehicle gate device 1 (step S101). When the target vehicle V arrives at the vehicle entrance 91, the vehicle gate device 1 uses the vehicle camera 12 to capture an image of the target vehicle V located at the vehicle entrance 91. Specifically, when the target vehicle V enters the entry-restricted area 9 through the vehicle entrance 91, the vehicle camera 12 captures an image of the target vehicle V located outside the entry-restricted area 9. The entry management server 5 may start the vehicle entry management operation shown in FIG. 9 when the vehicle camera 12 captures an image of the target vehicle V located outside the entry-restricted area 9.

[0074] Thereafter, the vehicle authentication unit 511 authenticates the target vehicle V using the vehicle image IMG_V acquired in step S101 and the registration information DB 521 stored in the storage device 52 (step S102). Note that in the second embodiment, the operation of authenticating the target vehicle V refers to the operation of determining whether the target vehicle V is a registered vehicle V_R. To authenticate the target vehicle V, the vehicle authentication unit 511 compares the vehicle number of the target vehicle V captured in the vehicle image IMG_V with the vehicle number of the registered vehicle V_R indicated by the vehicle information 5212 included in the registration information DB 521. If the registration information DB 521 includes vehicle information 5212 indicating the vehicle number of the registered vehicle V_R that is the same as the vehicle number of the target vehicle V, the vehicle authentication unit 511 determines that the target vehicle V is a registered vehicle V_R. In other words, the vehicle authentication unit 511 determines that the authentication of the target vehicle V has been successful. On the other hand, if the registration information DB 521 does not include vehicle information 5212 indicating the vehicle number of a registered vehicle V_R that is the same as the vehicle number of the target vehicle V, the vehicle authentication unit 511 determines that the target vehicle V is not a registered vehicle V_R. In other words, the vehicle authentication unit 511 determines that the authentication of the target vehicle V has failed.

[0075] If the authentication of the target vehicle V fails as a result of the authentication in step S102 (step S103: No), the target vehicle V located at the vehicle entrance 91 is not scheduled to enter the entry-restricted area 9. Therefore, in this case, the vehicle gate control unit 513 does not permit the target vehicle V to pass through the vehicle entrance 91 (step S109). Specifically, the vehicle gate control unit 513 generates a vehicle gate control signal for setting the state of the vehicle gate mechanism 11 to a closed state. The vehicle gate control unit 513 transmits the generated vehicle gate control signal to the vehicle gate device 1. As a result, the state of the vehicle gate mechanism 11 is set to a closed state, and the target vehicle V cannot pass through the vehicle entrance 91.

[0076] If the target vehicle V is not permitted to pass through the vehicle entrance 91, the vehicle gate control unit 513 may output warning information to a predetermined user, warning that the target vehicle V is not permitted to pass through the vehicle entrance 91. For example, the vehicle gate control unit 513 may output warning information to the administrator of the target vehicle V (i.e., the registered vehicle V_R), warning that the target vehicle V is not permitted to pass through the vehicle entrance 91, based on the administrator information included in the vehicle information 5212. For example, the vehicle gate control unit 513 may output warning information to an operator of the entrance management system SYS, warning that the target vehicle V is not permitted to pass through the vehicle entrance 91. The user may investigate the target vehicle V that was not permitted to pass through the vehicle entrance 91.

[0077] On the other hand, if the authentication of the target vehicle V is successful as a result of the authentication in step S102 (step S103: Yes), the person authentication unit 512 acquires a person image IMG_P1 from the user terminal 2 (step S104). Specifically, when the target vehicle V arrives at the vehicle entrance 91, the user terminal 2 provided on each target person P riding in the target vehicle V uses the camera 20 to capture an image of each target person P riding in the target vehicle V. In other words, each target person P riding in the target vehicle V captures an image of each target person P using the user terminal 2 provided on each target person P. The person authentication unit 512 acquires person images IMG_P1 for the number of target persons P riding in the target vehicle V.

[0078] Thereafter, the person authentication unit 512 authenticates the target person P using each person image IMG_P1 acquired in step S104 and the registration information DB 521 stored in the storage device 52 (step S105). Note that in the second embodiment, the operation of authenticating the target person P refers to the operation of determining whether the target person P is a registered person P_R. To authenticate the target person P, the person authentication unit 512 acquires, from the registration information DB 521, person information 5213 associated with vehicle information 5212 about the target vehicle V authenticated in step S102. The person authentication unit 512 compares each person image IMG_P1 acquired in step S104 with the registered image included in the person information 5213, thereby determining whether each target person P is a registered person P_R who is scheduled to enter the entry-restricted area 9 aboard the target vehicle V authenticated in step S102. For example, the person authentication unit 512 may extract feature amounts of each target person P (e.g., facial feature amounts of each target person P) based on each person image IMG_P1, and extract feature amounts of registered person P_R (e.g., facial feature amounts of registered person P_R) based on the registered image. Thereafter, the person authentication unit 512 may determine that each target person P is the registered person P_R when the similarity between the feature amount of each target person P and the feature amount of the registered person P_R exceeds a predetermined threshold. In other words, the person authentication unit 512 determines that the authentication of each target person P is successful. On the other hand, the person authentication unit 512 may determine that each target person P is not the registered person P_R when the similarity between the feature amount of each target person P and the feature amount of the registered person P_R is below a predetermined threshold. In other words, the person authentication unit 512 determines that the authentication of each target person P has failed.

[0079] As a result of the authentication in step S105, if authentication fails for at least one target person P who was the subject of authentication in step S105 (step S106: No), the target vehicle V is carrying a target person P who is not scheduled to enter the entry-restricted area 9. Therefore, in this case, the vehicle gate control unit 513 does not allow the target vehicle V to pass through the vehicle entrance 91 (step S109).

[0080] On the other hand, if the result of the authentication in step S105 is that authentication of all target persons P who were the subject of authentication in step S105 is successful (step S106: Yes), the person authentication unit 512 determines whether the number of target persons P who were successfully authenticated in step S105 is the same as the number of registered persons P_R who are scheduled to enter the entry-restricted area 9 by riding in the target vehicle V authenticated in step S102 (step S107). Note that, as described above, information regarding the number of registered persons P_R who are scheduled to enter the entry-restricted area 9 by riding in the target vehicle V is included in the vehicle information 5212 stored in the storage device 52.

[0081] If it is determined in step S107 that the number of successfully authenticated target persons P is not the same as the number of registered persons P_R (step S107: No), it is assumed that there is a registered person P_R who is scheduled to board the target vehicle V and enter the entry restricted area 9, but is not actually in the target vehicle V. In this case, the vehicle gate control unit 513 does not have to allow the target vehicle V to pass through the vehicle entrance 91 (step S109).

[0082] On the other hand, if it is determined in step S107 that the number of successfully authenticated target persons P is the same as the number of registered persons P_R (step S107: Yes), it is assumed that all registered persons P_R who are scheduled to enter the entry-restricted area 9 aboard the target vehicle V are aboard the target vehicle V. In this case, the vehicle gate control unit 513 allows the target vehicle V to pass through the vehicle entrance 91 (step S108). Specifically, the vehicle gate control unit 513 generates a vehicle gate control signal for setting the state of the vehicle gate mechanism 11 to an open state. The vehicle gate control unit 513 transmits the generated vehicle gate control signal to the vehicle gate device 1. As a result, the state of the vehicle gate mechanism 11 is set to an open state, and the target vehicle V is allowed to pass through the vehicle entrance 91.

[0083] (2-2-2) Person entry management operation Next, the flow of the person entrance management operation will be described with reference to Fig. 10. Fig. 10 is a flowchart showing the flow of the person entrance management operation.

[0084] 10, the person authentication unit 512 acquires a person image IMG_P2 from the person gate device 3 (step S111). When the target person P arrives at the person entrance 92, the person gate device 3 uses the person camera 32 to capture an image of the target person P located at the person entrance 92. Specifically, when the target person P enters the second restricted area 9B through the person entrance 92, the person camera 32 captures an image of the target person P located outside the second restricted area 9B (i.e., the first restricted area 9A). The entrance management server 5 may start the person entrance management operation shown in FIG. 10 when the person camera 32 captures an image of the target person P located outside the second restricted area 9B.

[0085] Thereafter, the person authentication unit 512 authenticates the target person P using the person image IMG_P2 acquired in step S111 and the registration information DB 521 stored in the storage device 52 (step S112). Note that the operation of authenticating the target person P in step S112 may be the same as the operation of authenticating the target person P in step S105 in Fig. 9 described above. Therefore, a detailed description of the operation of authenticating the target person P in step S112 in Fig. 10 will be omitted.

[0086] If the authentication of the target person P fails as a result of the authentication in step S112 (step S113: No), the target person P located at the person entrance 92 is not scheduled to enter the entry-restricted area 9. Therefore, in this case, the person gate control unit 514 does not permit the target person P to pass through the person entrance 92 (step S117). Specifically, the person gate control unit 514 generates a person gate control signal for setting the state of the person gate mechanism 31 to a closed state. The person gate control unit 514 transmits the generated person gate control signal to the person gate device 3. As a result, the state of the person gate mechanism 31 is set to a closed state, and the target person P cannot pass through the person entrance 92.

[0087] If the target person P is not permitted to pass through the person entrance 92, the person gate control unit 514 may output warning information to a predetermined user, warning that the target person P was not permitted to pass through the person entrance 92. For example, the person gate control unit 514 may output warning information to the administrator of the target vehicle V (i.e., registered vehicle V_R) in which the target person P was riding, based on administrator information included in the vehicle information 5212. For example, the person gate control unit 514 may output warning information to the operator of the entrance management system SYS, warning that the target person P was not permitted to pass through the person entrance 92. The user may investigate the target person P who was not permitted to pass through the person entrance 92.

[0088] On the other hand, if the authentication of the target person P is successful as a result of the authentication in step S112 (step S113: Yes), the person gate control unit 514 determines whether the authentication of the target person P at the vehicle entrance 91 was successful (step S114).

[0089] If it is determined in step S114 that the authentication of the target person P at the vehicle entrance 91 has not been successful (step S114: No), the target person P who has not been authenticated by the entrance management server 5 at the vehicle entrance 91 is located at the person entrance 92. For example, the target person P who has fraudulently passed through the vehicle entrance 91 without being authenticated by the entrance management server 5 by hiding inside the target vehicle V at the vehicle entrance 91 may be located at the person entrance 92. In this case, the person gate control unit 514 does not permit the target person P to pass through the person entrance 92 (step S117).

[0090] On the other hand, if it is determined as a result of the determination in step S114 that the authentication of the target person P at the vehicle entrance 91 has been successful (step S114: Yes), the person gate control unit 514 determines whether or not the target person P has taken safety training at the factory, which is the entry-restricted area 9 (step S115). As described above, the person information 5213 stored in the storage device 52 includes attendance information indicating whether or not the registered person P_R has taken safety training. In this case, the person gate control unit 514 may determine whether or not the target person P has taken safety training by determining whether or not the target person P is a registered person P_R who has taken safety training, based on the attendance information.

[0091] If it is determined in step S115 that the target person P has not received the safety training (step S115: No), it is assumed that it is preferable for the target person P to receive the safety training before entering the entry-restricted area 9. In this case, the person gate control unit 514 does not permit the target person P to pass through the person entrance 92 (step S117). Then, the person gate control unit 514 may urge the target person P to receive the safety training. For example, if the person gate device 3 is equipped with a display (or any output device), the person gate control unit 514 may control the display to display an image on the display to urge the target person P to receive the safety training.

[0092] On the other hand, if it is determined in step S115 that the target person P has received the safety training (step S115: Yes), the person gate control unit 514 allows the target person P to pass through the person entrance 92 (step S116). Specifically, the person gate control unit 514 generates a person gate control signal for setting the state of the person gate mechanism 31 to an open state. The person gate control unit 514 transmits the generated person gate control signal to the person gate device 3. As a result, the state of the person gate mechanism 31 is set to an open state, and the target person P can pass through the person entrance 92.

[0093] (2-2-3) Monitoring operation Next, the flow of the monitoring operation will be described with reference to Fig. 11. Fig. 11 is a flowchart showing the flow of the monitoring operation.

[0094] 11, the monitoring unit 515 acquires a monitoring image IMG_M from the monitoring camera 4 (step S121). The monitoring camera 4 captures an image of the imaging range 41 at a predetermined imaging rate. The entrance management server 5 may start the monitoring operation shown in FIG. 11 when the monitoring camera 4 generates the monitoring image IMG_M. The entrance management server 5 may start the monitoring operation shown in FIG. 11 when the monitoring camera 4 transmits the monitoring image IMG_M to the entrance management server 5.

[0095] Thereafter, the monitoring unit 515 analyzes the monitoring image IMG_M acquired in step S121 to determine whether a vehicle (specifically, the target vehicle V that has entered the restricted entry area 9) is captured in the monitoring image IMG_M (step S122).

[0096] As a result of the determination in step S122, if it is determined that the target vehicle V is captured in the monitoring image IMG_M (step S122: Yes), the monitoring unit 515 authenticates the target vehicle V using the monitoring image IMG_M acquired in step S121 and the registration information DB 521 stored in the storage device 52 (step S123). Note that the operation of authenticating the target vehicle V in step S123 may be the same as the operation of authenticating the target vehicle V in step S102 in Fig. 9. For this reason, a detailed description of the operation of authenticating the target vehicle V in step S123 in Fig. 11 will be omitted.

[0097] On the other hand, if it is determined in step S122 that the target vehicle V is not captured in the monitoring image IMG_M (step S122: No), the monitoring unit 515 does not need to perform the operation of step S123.

[0098] Furthermore, the monitoring unit 515 analyzes the monitoring image IMG_M acquired in step S121 to determine whether a person (specifically, the target person P who has entered the entry-restricted area 9) is captured in the monitoring image IMG_M (step S124).

[0099] As a result of the determination in step S124, if it is determined that the target person P appears in the monitoring image IMG_M (step S124: Yes), the monitoring unit 515 authenticates the target person P using the monitoring image IMG_M acquired in step S121 and the registration information DB 521 stored in the storage device 52 (step S125). Note that the operation of authenticating the target person P in step S125 may be the same as the operation of authenticating the target person P in step S105 in Fig. 9. Therefore, a detailed description of the operation of authenticating the target person P in step S125 in Fig. 11 will be omitted.

[0100] On the other hand, if it is determined in step S124 that the target person P does not appear in the monitoring image IMG_M (step S124: No), the monitoring unit 515 does not need to perform the operation of step S125.

[0101] Thereafter, the monitoring unit 515 determines whether the target vehicle V authenticated in step S123 is in an abnormal state (step S126). Furthermore, the monitoring unit 515 determines whether the target person P authenticated in step S125 is in an abnormal state (step S126).

[0102] For example, as described above, the registration information DB 521 includes, as part of the vehicle information 5212, vehicle entry permitted area information regarding a vehicle entry permitted area within the entry-restricted area 9 into which the registered vehicle V_R is permitted to enter. In this case, the monitoring unit 515 may determine whether the target vehicle V authenticated in step S123 is located in an area other than the vehicle entry permitted area, thereby determining whether the target vehicle V is in an abnormal state. Specifically, because the target vehicle V authenticated in step S123 is imaged by the monitoring camera 4, the monitoring unit 515 can identify the current location of the target vehicle V from the position of the imaging range 41 of the monitoring camera 4. Information regarding the position of the imaging range 41 of the monitoring camera 4 may be information known to the monitoring unit 515. Furthermore, the monitoring unit 515 can identify the vehicle entry permitted area of ​​the registered vehicle V_R corresponding to the target vehicle V based on the registration information DB 521. As a result, the monitoring unit 515 can determine whether the target vehicle V is located in an area other than the vehicle entry permitted area. If it is determined that the target vehicle V is located in an area different from the vehicle entry permitted area, it is assumed that the target vehicle V is located in an area into which the target vehicle V is not permitted to enter. In this case, the monitoring unit 515 may determine that the target vehicle V is in an abnormal state.

[0103] For example, as described above, the registration information DB 521 includes, as part of the person information 5213, person permitted area information regarding a person entry permitted area within the entry-restricted area 9 into which the registered person P_R is permitted to enter. In this case, the monitoring unit 515 may determine whether the target person P, authenticated in step S125, is located in an area different from the person entry permitted area, thereby determining whether the target person P is in an abnormal state. Specifically, because the target person P, authenticated in step S125, is imaged by the monitoring camera 4, the monitoring unit 515 can identify the current location of the target person P from the position of the imaging range 41 of the monitoring camera 4. Furthermore, the monitoring unit 515 can identify the person entry permitted area of ​​the registered person P_R corresponding to the target person P, based on the registration information DB 521. As a result, the monitoring unit 515 can determine whether the target person P is located in an area different from the person entry permitted area. If it is determined that the target person P is located in an area different from the person entry permitted area, it is assumed that the target person P is located in an area that the target person P is not permitted to enter. In this case, the monitoring unit 515 may determine that the target person P is in an abnormal state.

[0104] Alternatively, for example, the monitoring unit 515 may calculate the traveling speed of the target vehicle V by analyzing the monitoring image IMG_M, and determine that the target vehicle V is in an abnormal state if the calculated traveling speed exceeds the speed limit. If the target vehicle V is a special vehicle whose permitted traveling period during which it can travel on the road is limited, the monitoring unit 515 may identify the permitted traveling period of the target vehicle V by analyzing the monitoring image IMG_M, and determine that the target vehicle V is in an abnormal state if the identified permitted traveling period has already elapsed. For example, the monitoring unit 515 may analyze the monitoring image IMG_M to determine whether the target person P is smoking a cigarette, and determine that the target person P is in an abnormal state if the target person P is smoking a cigarette in a place other than a smoking area. For example, the monitoring unit 515 may determine that the target vehicle V is in an abnormal state if authentication of the target vehicle V fails in step S123 (i.e., if the target vehicle V is not a registered vehicle V_R and is located within the entry-restricted area 9). For example, the monitoring unit 515 may determine that the target person P is in an abnormal state if authentication of the target person P fails in step S125 (i.e., if the target person P is not a registered person P_R and is located within the restricted entry area 9).

[0105] If it is determined that the target vehicle V is in an abnormal state, the monitoring unit 515 may output warning information to a predetermined user, warning that the target vehicle V is in an abnormal state. For example, the monitoring unit 515 may output warning information to the administrator of the target vehicle V (i.e., the registered vehicle V_R) based on the administrator information included in the vehicle information 5212. For example, the monitoring unit 515 may output warning information to the operator of the entrance management system SYS, warning that the target vehicle V is in an abnormal state. The user may investigate the target vehicle V that is in an abnormal state.

[0106] If it is determined that the target person P is in an abnormal state, the monitoring unit 515 may output warning information to a predetermined user, warning that the target person P is in an abnormal state. For example, the monitoring unit 515 may output warning information to the manager of the target vehicle V (i.e., registered vehicle V_R) in which the target person P was riding, based on the manager information included in the vehicle information 5212. For example, the monitoring unit 515 may output warning information to the operator of the entrance management system SYS, warning that the target person P is in an abnormal state. The user may investigate the target person P who is in an abnormal state.

[0107] (2-2-4) Person exit management operation Next, the flow of the person exit management operation will be described with reference to Fig. 12. Fig. 12 is a flowchart showing the flow of the person exit management operation.

[0108] 12, the person authentication unit 512 acquires a person image IMG_P2 from the person gate device 3 (step S131). When the target person P arrives at the person entrance 92, the person gate device 3 uses the person camera 32 to capture an image of the target person P located at the person entrance 92. Specifically, when the target person P exits the second restricted area 9B through the person entrance 92, the person camera 32 captures an image of the target vehicle V located inside the second restricted area 9B. The entrance management server 5 may start the person exit management operation shown in FIG. 12 when the person camera 32 captures an image of the target person P located inside the second restricted area 9B.

[0109] Thereafter, the person authentication unit 512 authenticates the target person P using the person image IMG_P2 acquired in step S111 and the registration information DB 521 stored in the storage device 52 (step S132). Note that the operation of authenticating the target person P in step S132 may be the same as the operation of authenticating the target person P in step S112 in Fig. 10 described above. Therefore, a detailed description of the operation of authenticating the target person P in step S132 in Fig. 12 will be omitted.

[0110] If the authentication of the target person P fails as a result of the authentication in step S132 (step S133: No), it is assumed that the target person P located at the person entrance 92 has been staying in the entrance restricted area 9 despite not being scheduled to enter the entrance restricted area 9. Therefore, in this case, the person gate control unit 514 does not permit the target person P to pass through the person entrance 92 (step S135). Note that the operation of step S135 may be the same as the operation of step S117 in FIG. 10 described above. Therefore, a detailed description of the operation of step S135 in FIG. 12 will be omitted.

[0111] If the target person P is not permitted to pass through the person entrance 92, the person gate control unit 514 may output warning information to a predetermined user, warning that the target person P was not permitted to pass through the person entrance 92. For example, the person gate control unit 514 may output warning information to the administrator of the target vehicle V (i.e., registered vehicle V_R) in which the target person P was riding, warning that the target person P was not permitted to pass through the person entrance 92, based on administrator information included in the vehicle information 5212. For example, the person gate control unit 514 may output warning information to the operator of the entrance management system SYS, warning that the target person P was not permitted to pass through the person entrance 92. The user may investigate the target person P who was not permitted to pass through the person entrance 92 (i.e., the target person P who was staying in the entry-restricted area 9 despite not being scheduled to enter the entry-restricted area 9).

[0112] On the other hand, if the authentication of the target person P is successful as a result of the authentication in step S112 (step S133: Yes), the person gate control unit 514 allows the target person P to pass through the person entrance 92 (step S134). Note that the operation of step S134 may be the same as the operation of step S116 in Fig. 10 described above. Therefore, a detailed description of the operation of step S134 in Fig. 12 will be omitted.

[0113] (2-2-5) Vehicle Exit Management Next, the flow of the vehicle exit management operation will be described with reference to Fig. 13. Fig. 13 is a flowchart showing the flow of the vehicle exit management operation.

[0114] 13, the vehicle authentication unit 511 acquires a vehicle image IMG_V from the vehicle gate device 1 (step S141). When the target vehicle V arrives at the vehicle entrance 91, the vehicle gate device 1 uses the vehicle camera 12 to capture an image of the target vehicle V located at the vehicle entrance 91. Specifically, when the target vehicle V exits the entry-restricted area 9 through the vehicle entrance 91, the vehicle camera 12 captures an image of the target vehicle V located inside the entry-restricted area 9 (specifically, the first restricted area 9A). The entry management server 5 may start the vehicle entry management operation shown in FIG. 9 when the vehicle camera 12 captures an image of the target vehicle V located inside the entry-restricted area 9.

[0115] Thereafter, the entrance management server 5 performs operations from step S142 to step S149, which may be the same as the operations from step S102 to step S109 of the vehicle entrance management operation shown in Fig. 9. That is, the vehicle authentication unit 511 authenticates the target vehicle V using the vehicle image IMG_V acquired in step S141 and the registration information DB 521 stored in the storage device 52 (step S142). If the authentication of the target vehicle V fails as a result of the authentication in step S142 (step S143: No), the vehicle gate control unit 513 does not permit the target vehicle V to pass through the vehicle entrance 91 (step S149). On the other hand, if the authentication of the target vehicle V succeeds as a result of the authentication in step S142 (step S143: Yes), the person authentication unit 512 acquires a person image IMG_P1 from the user terminal 2 (step S144). Thereafter, the person authentication unit 512 authenticates the target person P using each person image IMG_P1 acquired in step S144 and the registration information DB 521 stored in the storage device 52 (step S145). If, as a result of the authentication in step S145, authentication of at least one target person P who was the target of authentication in step S145 fails (step S146: No), the vehicle gate control unit 513 does not permit the target vehicle V to pass through the vehicle entrance 91 (step S149). On the other hand, if, as a result of the authentication in step S145, authentication of all target persons P who were the target of authentication in step S145 is successful (step S146: Yes), the person authentication unit 512 determines whether the number of target persons P who were successfully authenticated in step S145 is the same as the number of registered persons P_R who are scheduled to enter the entry-restricted area 9 by getting on the target vehicle V authenticated in step S142 (and, as a result, are naturally scheduled to exit the entry-restricted area 9) (step S147). If the result of the judgment in step S147 is that the number of target persons P who have been successfully authenticated is not the same as the number of registered persons P_R (step S147: No), the vehicle gate control unit 513 may not allow the target vehicle V to pass through the vehicle entrance 91 (step S149).On the other hand, if the result of the judgment in step S147 is that the number of target persons P who have been successfully authenticated is the same as the number of registered persons P_R (step S147: Yes), the vehicle gate control unit 513 allows the target vehicle V to pass through the vehicle entrance 91 (step S148).

[0116] (2-3) Technical effects of the admission management system SYS As described above, the entrance management system SYS uses the vehicle image IMG_V, the person image IMG_P1, and the registration information DB 521 at the vehicle entrance 91 to determine whether or not to permit the target vehicle V to pass through the vehicle entrance 91. This eliminates the need for the target person P to get out of the target vehicle V at the vehicle entrance 91 and fill out necessary documents in order to enter the entry-restricted area 9. This allows the target person P to enter the entry-restricted area 9 while remaining in the target vehicle V. This reduces the time required to enter the entry-restricted area 9. As a result, the possibility of a large number of target vehicles V wishing to enter the entry-restricted area 9 remaining at the vehicle entrance 91 (resulting in traffic congestion) is reduced. This allows the entrance management system SYS to solve the technical problem of a large number of target vehicles V wishing to enter the entry-restricted area 9 remaining at the vehicle entrance 91.

[0117] Furthermore, the entrance control system SYS permits the target vehicle V to pass through the vehicle entrance 91 when the target vehicle V is determined to be a registered vehicle V_R and the target person P is determined to be a registered person P_R. Therefore, compared to a case in which the target vehicle V is permitted to pass through the vehicle entrance 91 even when the target vehicle V is determined to be a registered vehicle V_R but the target person P is not determined to be a registered person P_R, the entrance control system SYS can more appropriately prevent the suspicious target person P from entering the entry-restricted area 9. Similarly, compared to a case in which the target vehicle V is permitted to pass through the vehicle entrance 91 even when the target person P is determined to be a registered person P_R but the target vehicle V is not determined to be a registered vehicle V_R, the entrance control system SYS can more appropriately prevent the suspicious target person P from entering the entry-restricted area 9. Therefore, the entrance control system SYS can solve the technical problem of the possibility of the suspicious target person P entering the entry-restricted area 9.

[0118] Furthermore, the entrance management system SYS allows the target vehicle V to pass through the vehicle entrance 91 when the number of successfully authenticated target persons P is the same as the number of registered persons P_R who are scheduled to board the successfully authenticated target vehicle V and enter the restricted entry area 9. Therefore, compared to when the number of target persons P is not taken into consideration, the entrance management system SYS can more appropriately prevent suspicious target persons P from entering the restricted entry area 9.

[0119] Furthermore, in addition to determining whether or not to permit the target vehicle V to pass through the vehicle entrance 91, the entrance control system SYS also determines whether or not to permit the target person P to pass through the person entrance 92. Therefore, even if there is a target person P who has illegally passed through the vehicle entrance 91, the target person P will not be permitted to pass through the person entrance 92. Therefore, the entrance control system SYS can more appropriately prevent suspicious target persons P from entering the restricted entry area 9 (particularly the second restricted area 9B).

[0120] Furthermore, the entrance management system SYS does not permit a target person P who has not received safety training to pass through the person entrance gate 92. Therefore, compared to when a target person P who has not received safety training is permitted to pass through the person entrance gate 92, the entrance management system SYS can more reliably ensure safety within the factory, which is an entrance restricted area 9.

[0121] Furthermore, the entrance control system SYS performs a monitoring operation to monitor the behavior of the target person P who has entered the entrance restricted area 9 within the entrance restricted area 9. Therefore, the entrance control system SYS can identify at least one of the target person P and the target vehicle V that is in an abnormal state. As a result, the entrance control system SYS can appropriately resolve the abnormal state compared to when the monitoring operation is not performed.

[0122] (2-4) Modification In the above description, in the vehicle entry management operation of Fig. 9, the entry management server 5 determines whether the number of target persons P who were successfully authenticated in step S105 is the same as the number of registered persons P_R who are scheduled to enter the entry-restricted area 9 by riding in the target vehicle V authenticated in step S102 (step S107 in Fig. 9). However, the entry management server 5 does not have to perform the operation of step S107 in Fig. 9.

[0123] In the above description, in the person entrance management operation of Fig. 10, the entrance management server 5 determines whether or not authentication of the target person P at the vehicle entrance 91 was successful (step S114 of Fig. 10). However, the entrance management server 5 does not have to perform the operation of step S114 of Fig. 10.

[0124] In the above description, in the person entry management operation of FIG. 10 , the entry management server 5 determines whether or not the target person P has taken safety training (step S115 of FIG. 10 ). However, the entry management server 5 does not have to perform the operation of step S115 of FIG. 10 . If the entry management server 5 does not perform the operation of step S115 of FIG. 10 , the registration information DB 521 does not have to include attendance information indicating whether or not the registered person P_R has taken safety training. Alternatively, in addition to or instead of determining whether or not the target person P has taken safety training in the person entry management operation of FIG. 10 , the entry management server 5 may determine whether or not the target person P located at the vehicle entry gate 91 (i.e., the target person P riding in the target vehicle V located at the vehicle entry gate 91) has taken safety training in the vehicle entry management operation of FIG. 9 . In this case, if it is determined that the target person P has not taken safety training, the entry management server 5 does not have to allow the target vehicle V to pass through the vehicle entry gate 91. In addition, the entrance management server 5 may urge the target person P to take safety training.

[0125] 10, the entrance management server 5 may determine whether a predetermined valid period has elapsed since the target person P last took safety training. In other words, the entrance management server 5 may determine whether the target person P has taken safety training within the valid period. If it is determined that the valid period has elapsed since the target person P last took safety training (in other words, the target person P has not taken safety training within the valid period), the entrance management server 5 may not permit the target person P to pass through the person entrance gate 92. In addition, the entrance management server 5 may urge the target person P to take safety training.

[0126] In the vehicle exit management operation of FIG. 13 , if a target vehicle V has exited the entry restricted area 9 but a registered person P_R who is scheduled to enter the entry restricted area 9 by riding in the target vehicle V (and is therefore naturally scheduled to exit the entry restricted area 9) has not exited the entry restricted area 9, the vehicle gate control unit 513 may output warning information to a predetermined user, warning that the registered person P_R has not exited the entry restricted area 9. For example, the vehicle gate control unit 513 may output warning information to a manager of the target vehicle V, warning that the registered person P_R has not exited the entry restricted area 9. For example, the vehicle gate control unit 513 may output warning information to a manager of the target vehicle V, warning that the registered person P_R has not exited the entry restricted area 9, to an operator of the admission management system SYS. The user may investigate the reason why the registered person P_R has not exited the entry restricted area 9.

[0127] In the vehicle exit management operation of FIG. 13 , if a registered person P_R who is scheduled to enter the entry restricted area 9 by riding in the target vehicle V (and is therefore naturally scheduled to exit the entry restricted area 9) has exited the entry restricted area 9, even though the target vehicle V has not exited the entry restricted area 9, the vehicle gate control unit 513 may output warning information to a predetermined user, warning that the target vehicle V has not exited the entry restricted area 9. For example, the vehicle gate control unit 513 may output warning information to a manager of the target vehicle V, warning that the target vehicle V has not exited the entry restricted area 9. For example, the vehicle gate control unit 513 may output warning information to an operator of the entrance management system SYS, warning that the target vehicle V has not exited the entry restricted area 9. The user may investigate the reason why the target vehicle V has not exited the entry restricted area 9.

[0128] In the above description, in the vehicle exit management operation of Fig. 13, the entrance management server 5 determines whether or not the number of target persons P who were successfully authenticated in step S145 is the same as the number of registered persons P_R who are scheduled to enter the entry restricted area 9 by getting on the target vehicle V authenticated in step S142 (and, as a result, are naturally scheduled to exit from the entry restricted area 9) (step S147 of Fig. 13). However, the entrance management server 5 does not have to perform the operation of step S147 of Fig. 13.

[0129] In the above description, in the vehicle exit management operation of FIG. 13, the entrance management server 5 authenticates the target person P (steps S144 to S146 of FIG. 13). However, the entrance management server 5 does not have to perform the operations of steps S144 to S146 of FIG. 13. In this case, the target person P can exit the entrance restricted area 9 by getting into a vehicle different from the target vehicle V that he or she got into to enter the entrance restricted area 9. For example, in a situation where a first target person P and a second target person P2 get into the first target vehicle V and enter the entrance restricted area 9, the first target person P, who completes a task before the second target person P, can exit the entrance restricted area 9 without waiting for the second target person P to complete his or her task. This allows for flexibility in the exit time.

[0130] In the above description, the entrance management server 5 performs vehicle entry management operations, person entry management operations, monitoring operations, person exit operations, and vehicle exit operations. However, the entrance management server 5 does not have to perform at least one of the vehicle entry management operations, person entry management operations, monitoring operations, person exit operations, and vehicle exit operations. If the entrance management server 5 does not perform vehicle entry management operations or vehicle exit management operations, the entrance management system SYS does not have to include the vehicle gate device 1 and the user terminal 2, and the entrance management server 5 does not have to include the vehicle authentication unit 511 and the vehicle gate control unit 513. If the entrance management server 5 does not perform person entry management operations or person exit management operations, the entrance management system SYS does not have to include the person gate device 3, and the entrance management server 5 does not have to include the person authentication unit 512 and the person gate control unit 514. If the entrance management server 5 does not perform monitoring operations, the entrance management system SYS does not have to include the surveillance camera 4, and the entrance management server 5 does not have to include the monitoring unit 515.

[0131] In the above description, the entry restricted area 9 is provided with a person entrance 92. However, the entry restricted area 9 does not have to be provided with a person entrance 92. The entry restricted area 9 does not have to be divided into a first restricted area 9A and a second restricted area 9B by the person entrance 92. In this case, the entrance management system SYS does not have to be equipped with a person gate device 2 placed at the person entrance 92. The entrance management server 5 does not have to perform person entry management operations and person exit management operations based on the person image IMG_P2 generated by the person gate device 2.
