[0027] The method for implementing the object of the present disclosure is described with reference to the accompanying drawings. In each figure, the same reference numerals are marked for the same or equivalent parts, and repeated descriptions are appropriately simplified or omitted. In addition, the object of the present disclosure is not limited to the following embodiments, and any structural elements of the embodiments can be deformed or omitted without departing from the scope of the present disclosure.

[0028] Implementation method 1.

[0029] Figure 1 This is a configuration diagram of the entry and exit management system 1 according to the first embodiment.

[0030] The access management system 1 is applied to a facility. The facility is, for example, an indoor facility or an outdoor facility, or a facility obtained by combining them. The facility is, for example, composed of one or more buildings. The facility may also be, for example, a part of a building. A management area is set in the facility. The management area is a pre-set area inside or outside the facility. The access management system 1 is a system for managing the entry or exit of users into or out of the management area.

[0031] In the access management system 1 of this example, a door 3 equipped with an electronic lock 2 is provided at an entrance and exit on the boundary of the management area. The boundary of the management area may also include boundary areas such as the space at the periphery of the management area and the space adjacent to the management area. The door 3 is provided, for example, at the entrance of a building or at the entrance and exit of a room inside the building. In the access management system 1, a security door or the like may be provided at the entrance and exit on the boundary of the management area instead of or together with the door 3.

[0032] A user of the entry and exit management system 1 who passes through the boundary of the management area, for example, holds a wireless communication device 4 and passes through the facility. A user who can pass through the boundary of the management area is, for example, a person or an autonomous mobile body that is allowed to enter or exit the management area. The wireless communication device 4 moves in the facility together with the passage of the user. The wireless communication device 4 may be, for example, a portable general-purpose information processing device such as a smartphone held by the user or a smart watch worn by the user, or may be a dedicated device of the entry and exit management system 1 such as a wireless tag held by the user. The wireless communication device 4 may be, for example, a wireless communication module built into the autonomous mobile body when the user is an autonomous mobile body. The wireless communication device 4 is equipped with a function of communicating wireless signals. The wireless communication device 4 stores identification information for identifying itself or identification information for identifying a user passing with it. The identification information is, for example, a unique ID (IDentifier) ​​assigned to the wireless communication device 4 or the user in the entry and exit management system 1. The wireless communication device 4 transmits a wireless signal containing the stored identification information. The wireless signal is, for example, a signal of UWB (Ultra Wide Band) or other standards.

[0033] The entry and exit management system 1 includes an entry and exit management device 5 and a pass determination device 6. The entry and exit management device 5 and the pass determination device 6 are connected in a communicative manner via a communication network 7. The communication network 7 may be, for example, a local area network such as a LAN (Local Area Network) within a facility, or a wide area network such as the Internet or a telephone line network.

[0034] The entry and exit management device 5 is a device for managing the entry and exit of the area, such as authentication processing of users who attempt to pass through the boundary of the management area. The authentication processing is, for example, a process for determining whether to allow the user to enter or exit the management area based on the identification information of the user or the wireless communication device 4 that moves with the user. The entry and exit management device 5 functions as a higher-level control device in the entry and exit management system 1. The entry and exit management device 5 is composed of, for example, one or more server computers. Part or all of the entry and exit management device 5 can be set in the facility or outside the facility. Part or all of the functions of the entry and exit management device 5 can also be installed through processing or storage resources on a cloud service.

[0035] The access management device 5 includes an authentication unit 8 and a lock control unit 9. The authentication unit 8 is a part that performs information processing in the authentication process, such as determining whether the authentication of the identification information is passed, and the identification information is obtained through the communication network 7 or the like. The determination of whether the authentication of the identification information is passed is performed, for example, based on whether the identification information is included in a pre-set access permission list. The lock control unit 9 is a part that controls the locking and unlocking of the electronic lock 2 through the communication network 7 or the like. For example, when the authentication unit 8 determines that the authentication is passed, the lock control unit 9 outputs an instruction to unlock the electronic lock 2. The lock control unit 9 can also obtain information on the locking and unlocking status of the electronic lock 2 and the opening and closing status of the door 3 through the communication network 7 or the like.

[0036] The passage determination device 6 is installed at the boundary of the management area. In this example, the passage determination device 6 is installed on the wall surface that separates the inside and outside of the management area, adjacent to the entrance and exit of the management area on the outside of the management area. The passage determination device 6 includes a receiver 10, a storage unit 11, a calculation unit 12, a determination unit 13, and a communication unit 14.

[0037] The receiver 10 is built into the passage determination device 6. The receiver 10 is equipped with a function of receiving a wireless signal transmitted by the wireless communication device 4. A single receiver 10 is provided at a position at the boundary of the management area as an internal device of the passage determination device 6. The receiver 10 includes one or more antennas. In this example, the receiver 10 includes a plurality of antennas. In the entry and exit management system 1, the receiver 10 does not need to be provided in a manner that surrounds the entire boundary of the management area.

[0038] The storage unit 11 is a part equipped with a function of storing information. The storage unit 11 stores, for example, information of a determination area. The determination area is a pre-set area for determining whether the passage of a user is detected. The determination area is set, for example, at the entrance and exit of a management area. In this example, the determination area is a three-dimensional area. The determination area is, for example, an area leading to the entrance and exit of a management area that is set adjacent to the passage determination device 6. For example, the determination area is set based on a relative position based on the passage determination device 6. For example, the determination area can also be set by selecting from a plurality of shapes of areas.

[0039] The calculation unit 12 is a part equipped with a function of calculating the three-dimensional position of the wireless communication device 4. The calculation unit 12 calculates the three-dimensional position of the wireless communication device 4 that has transmitted the wireless signal by, for example, performing distance measurement and angle measurement using the wireless signal received by the receiver 10. The three-dimensional position of the wireless communication device 4 is represented by, for example, relative coordinates based on the passage determination device 6. In this example, the three-dimensional position of the wireless communication device 4 is represented by, for example, coordinates (x, y, z) of a three-dimensional orthogonal coordinate system such as a Cartesian coordinate system. In addition, the three-dimensional position of the wireless communication device 4 may also be represented by coordinates of a three-dimensional orthogonal curvilinear coordinate system such as a polar coordinate system. Etc. indicates.

[0040] The calculation unit 12 obtains the distance information between the wireless communication device 4 that has transmitted the wireless signal and the passage determination device 6 based on, for example, a distance measurement method using the signal strength of the wireless signal received by the receiver 10. The signal strength is, for example, an RSSI value (RSSI: Received Signal Strength Indicator). Alternatively, the calculation unit 12 may obtain the distance information between the wireless communication device 4 that has transmitted the wireless signal and the passage determination device 6 by, for example, a distance measurement method such as the ToF method (ToF: Time of Flight). In this case, the calculation unit 12 may perform distance measurement using the propagation time of a single channel of the wireless signal by synchronizing with the wireless communication device 4, or may perform distance measurement using the propagation time of the wireless signal required for round trip by transmitting and receiving wireless signals with the wireless communication device 4. Here, the wireless signal transmitted by the wireless communication device 4 may be, for example, a response signal to an inquiry signal transmitted by the passage determination device 6 at the periphery of the entrance and exit of the management area by the wireless signal.

[0041] The calculation unit 12 obtains the angle information of the wireless communication device 4 that has transmitted the wireless signal based on the passage determination device 6, for example, based on a method of measuring angles using the wireless signal received by the receiver 10. The calculation unit 12 may also obtain the arrival direction of the wireless signal from the wireless communication device 4, that is, the angle information of the wireless communication device 4, by an angle measurement method such as the PDoA method (PDoA: Phase Difference of Arrival). The calculation unit 12 obtains the arrival direction of the wireless signal based on the phase difference of the wireless signal received by the multiple antennas mounted on the receiver 10. In addition, for example, in the case where the wireless communication device 4 transmits multiple wireless signals simultaneously from multiple antennas, the calculation unit 12 may also obtain the arrival direction of the multiple wireless signals based on the phase difference between the multiple wireless signals received by a single antenna mounted on the receiver 10.

[0042] The determination unit 13 is a part equipped with a function of determining whether the wireless communication device 4 is located in the determination area. The determination unit 13 makes this determination by comparing the three-dimensional position of the wireless communication device 4 calculated by the calculation unit 12 with the determination area information stored in the storage unit 11, for example.

[0043] The communication unit 14 is a part equipped with a function of transmitting the identification information transmitted from the wireless communication device 4 to the entry and exit management device 5 via the communication network 7 or the like. The communication unit 14 controls the transmission of the identification information to the entry and exit management device 5 based on the determination result of whether the wireless communication device 4 is located in the determination area by the determination unit 13. In this example, when the communication unit 14 determines that the wireless communication device 4 is located in the determination area, the identification information transmitted from the wireless communication device 4 is transmitted to the authentication unit 8 of the entry and exit management device 5. On the other hand, when the communication unit 14 does not determine that the wireless communication device 4 is located in the determination area, the identification information transmitted from the wireless communication device 4 is not transmitted to the authentication unit 8 of the entry and exit management device 5.

[0044] Figure 2 This is a diagram showing an example in which the calculation unit 12 of the traffic determination device 6 according to the first embodiment calculates the three-dimensional position of the wireless communication device 4 .

[0045] In this example, the origin O indicates the position of the traffic determination device 6. The direction of the z-axis indicates the vertical direction. The xy plane indicates the horizontal plane. The direction of the x-axis indicates the in-plane direction of the wall surface on which the traffic determination device 6 is installed. The direction of the y-axis indicates the normal direction of the wall surface on which the traffic determination device 6 is installed. Point p indicates the position of the wireless communication device 4. Point h indicates the foot of a perpendicular line drawn from point p to the horizontal plane passing through the position O of the traffic determination device 6.

[0046] The calculation unit 12 measures the distance using the wireless signal received by the receiver 10, and obtains the straight-line distance rp between the passage determination device 6 and the wireless communication device 4. In addition, the calculation unit 12 measures the angle using the wireless signal received by the receiver 10, and obtains the angle information of the wireless communication device 4 with respect to the passage determination device 6. The angle information includes, for example, the pitch angle θ and the azimuth angle The pitch angle θ represents the angle in the up-down direction relative to the horizontal plane. The calculation unit 12 uses, for example, the straight-line distance rp, the pitch angle θ, and the azimuth angle The coordinates (xp, yp, zp) of the three-dimensional orthogonal coordinate system are calculated as the three-dimensional position of the wireless communication device 4. The calculation unit 12 may use, for example, the linear distance rp, the elevation angle θ, and the azimuth angle Calculate the coordinates of a 3D cylindrical coordinate system Here, the distance rh represents the horizontal distance between the passage determination device 6 and the wireless communication device 4. For example, the distance rh is calculated using the straight-line distance rp and the pitch angle θ. In addition, the calculation unit 12 may also calculate the straight-line distance rp, the pitch angle θ, and the azimuth angle Itself serves as the three-dimensional position of the wireless communication device 4.

[0047] Figure 3 This is a diagram showing a first example of the determination area set in the entry and exit management system 1 according to the first embodiment.

[0048] The judgment area is set, for example, in a cylindrical area with the vertical direction as the axial direction. In this example, the judgment area is set in a quadrangular prism area with a rectangular bottom surface. For example, the judgment area is set according to the range of xy coordinates in the horizontal plane. For example, the judgment area is set according to the interval [x1, x2] representing the range of the x coordinate and the interval [y1, y2] representing the range of the y coordinate.

[0049] The determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the position of the wireless communication device 4 in the horizontal plane obtained from the three-dimensional position of the wireless communication device 4. For example, when the coordinate value xp of the x coordinate of the three-dimensional position of the wireless communication device 4 is included in the interval [x1, x2] and the coordinate value yp of the y coordinate of the three-dimensional position of the wireless communication device 4 is included in the interval [y1, y2], the determination unit 13 determines that the wireless communication device 4 is located in the determination area. In this case, the determination unit 13 can determine whether the wireless communication device 4 is located in the determination area regardless of the height of the wireless communication device 4. In addition, when the coordinate value xp of the x coordinate is not included in the interval [x1, x2], the determination unit 13 may determine that the wireless communication device 4 is not located in the determination area without performing a determination based on the coordinate value yp of the y coordinate. Similarly, when the coordinate value yp of the y coordinate is not included in the interval [y1, y2], the determination unit 13 may determine that the wireless communication device 4 is not located in the determination area without performing a determination based on the coordinate value xp of the x coordinate.

[0050] In addition, in the cylindrical determination area, for example, a height range can also be set. In this example, the determination area can also be a rectangular area with a specified height range. In this case, the height range of the determination area is set according to the interval [z1, z2] representing the range of the z coordinate. When the condition that the position of the wireless communication device 4 in the horizontal plane is located in the determination area is satisfied, and the coordinate value zp of the z coordinate of the three-dimensional position of the wireless communication device 4 is included in the interval [z1, z2], the determination unit 13 determines that the wireless communication device 4 is located in the determination area.

[0051] Figure 4 This is a diagram showing a second example of the determination area set in the entry and exit management system 1 according to the first embodiment.

[0052] The determination area is set, for example, as a cylindrical area with a vertical direction as an axial direction and a circular bottom surface. The axis of the cylindrical area is set, for example, on a vertical line passing through the passage determination device 6. The determination area is set, for example, based on the maximum value rm of the horizontal distance from the passage determination device 6.

[0053] The determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the position of the wireless communication device 4 in the horizontal plane obtained from the three-dimensional position of the wireless communication device 4. For example, when the horizontal distance rh between the passage determination device 6 and the wireless communication device 4 is less than the distance rm, the determination unit 13 determines that the wireless communication device 4 is located in the determination area.

[0054] In addition, the determination area may be, for example, a semi-cylindrical area outside the management area. In this case, when the horizontal distance rh between the passage determination device 6 and the wireless communication device 4 is less than the distance rm and the wireless communication device 4 is located outside the management area, the determination unit 13 determines that the wireless communication device 4 is located within the determination area. Whether the wireless communication device 4 is located outside the management area is determined based on, for example, the azimuth of the three-dimensional position of the wireless communication device 4. Or the coordinate value yp of the y coordinate, etc. In addition, the axis of the determination zone as a cylindrical area can also be set to a position that does not pass through the passage determination device 6. In this case, the determination zone is set, for example, based on the position of the axis in the horizontal plane and the maximum value rm of the horizontal distance from the axis.

[0055] Figure 5 This is a diagram showing a third example of the determination area set in the entry and exit management system 1 according to the first embodiment.

[0056] The determination area is set, for example, as a cylindrical area with the vertical direction as the axial direction and the bottom surface as a fan. The axis of the cylindrical area is set, for example, on the plumb line passing through the passage determination device 6. In this example, the axis of the cylindrical area passes through the center of the fan-shaped bottom surface. The center of the fan-shaped is the point where two line segments passing through the two ends of the arc and forming the outer periphery of the fan-shaped intersect. For example, based on the maximum value rm of the horizontal distance from the passage determination device 6 and the azimuth angle The range of To set the judgment area.

[0057] The determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the position of the wireless communication device 4 in the horizontal plane obtained from the three-dimensional position of the wireless communication device 4. For example, the determination unit 13 determines whether the wireless communication device 4 is located in the determination area when the horizontal distance rh between the passage determination device 6 and the wireless communication device 4 is less than the distance rm and the azimuth of the three-dimensional position of the wireless communication device 4 is Included in the interval In addition, the determination unit 13 determines that the wireless communication device 4 is located in the determination area. Not included in the interval In the case where the horizontal distance rh exceeds the distance rm, the determination unit 13 may determine that the wireless communication device 4 is not located in the determination area without performing the determination based on the horizontal distance rh. In this case, the determination unit 13 can determine that the wireless communication device 4 is not located in the determination area without using the distance measurement information. Similarly, the determination unit 13 may determine that the wireless communication device 4 is not located in the determination area without performing the determination based on the azimuth angle when the horizontal distance rh exceeds the distance rm. The wireless communication device 4 is determined not to be located in the determination area. In addition, the cylindrical area may be a semi-cylindrical area whose central angle of the fan-shaped bottom surface is 180°. In addition, in the cylindrical area, the central angle of the fan-shaped bottom surface may be greater than 180° or less than 180°. In addition, the axis of the determination area as the cylindrical area may also be set to a position that does not pass through the passage determination device 6. At this time, for example, based on the position of the axis in the horizontal plane, the maximum value rm of the horizontal distance from the axis, and the azimuth The judgment area is set by the range of

[0058] Figure 6 This is a diagram showing a fourth example of the determination area set in the entry and exit management system 1 according to the first embodiment.

[0059] The determination area is set, for example, in a spherical area. The center of the spherical area is set, for example, at the position of the passage determination device 6. The determination area is set, for example, based on the maximum value rs of the straight-line distance from the passage determination device 6.

[0060] The determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the three-dimensional position of the wireless communication device 4. For example, when the straight-line distance rp between the passage determination device 6 and the wireless communication device 4 is less than the distance rs, the determination unit 13 determines that the wireless communication device 4 is located in the determination area.

[0061] In addition, the determination area may be, for example, a hemispherical area such as the outside of the management area. In this case, when the straight-line distance rp between the passage determination device 6 and the wireless communication device 4 is less than the distance rs and the wireless communication device 4 is located outside the management area, the determination unit 13 determines that the wireless communication device 4 is located within the determination area. Whether the wireless communication device 4 is located outside the management area is determined based on, for example, the azimuth of the three-dimensional position of the wireless communication device 4. Or the y coordinate value yp, etc. The center of the determination area as a spherical area may be set outside the position of the traffic determination device 6. In this case, the determination area is set based on, for example, the position of the center and the maximum value rs of the straight line distance from the center.

[0062] Next, use Figure 7 An example of the operation of the entry and exit management system 1 will be described.

[0063] Figure 7 This is a flowchart showing an example of the operation of the entry and exit management system 1 according to the first embodiment.

[0064] In step S11, the traffic determination device 6 determines whether the receiver 10 receives a wireless signal from the wireless communication device 4. If the receiver 10 receives a wireless signal, the traffic determination device 6 proceeds to step S12. On the other hand, if the receiver 10 does not receive a wireless signal, the traffic determination device 6 performs step S11 again.

[0065] In step S12, the calculation unit 12 calculates the three-dimensional position of the wireless communication device 4 by measuring the distance and angle using the wireless signal received by the receiver 10. Thereafter, the process of the passage determination device 6 proceeds to step S13.

[0066] In step S13, the determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the three-dimensional position of the wireless communication device 4 calculated by the calculation unit 12. If the determination unit 13 determines that the wireless communication device 4 is located in the determination area, the process of the passage determination device 6 proceeds to step S14. On the other hand, if the determination unit 13 does not determine that the wireless communication device 4 is located in the determination area, the process of the passage determination device 6 ends.

[0067] In step S14, the communication unit 14 transmits the identification information included in the wireless signal received by the receiver 10 to the authentication unit 8 of the entry and exit management device 5. Thereafter, the processing of the passage determination device 6 ends.

[0068] In step S21, the entry and exit management device 5 determines whether the identification information transmitted from the wireless communication device 4 is received from the passage determination device 6. If the identification information is received, the process of the entry and exit management device 5 proceeds to step S22. On the other hand, if the identification information is not received, the entry and exit management device 5 performs the process of step S21 again.

[0069] In step S22, the authentication unit 8 determines whether the received identification information can be authenticated. If the identification information can be authenticated, the process of the entry and exit management device 5 proceeds to step S23. On the other hand, if the identification information cannot be authenticated, the process of the entry and exit management device 5 ends.

[0070] In step S23, the lock control unit 9 outputs a command to unlock the electronic lock 2. In accordance with the command from the lock control unit 9, the electronic lock 2 is unlocked in the door 3. Thereafter, the processing of the entry and exit management device 5 ends.

[0071] As described above, the entry and exit management system 1 of the first embodiment includes a wireless communication device 4, an entry and exit management device 5, and a passage determination device 6. The wireless communication device 4 moves as the user passes. The wireless communication device 4 transmits a wireless signal including the stored identification information. The entry and exit management device 5 performs authentication processing based on the received identification information. The passage determination device 6 includes a receiver 10, a calculation unit 12, a determination unit 13, and a communication unit 14. The receiver 10 is provided at a position on the boundary of the management area. The receiver 10 receives the wireless signal including the identification information stored in the wireless communication device 4 transmitted from the wireless communication device 4. The calculation unit 12 calculates the three-dimensional position of the wireless communication device 4 that transmitted the wireless signal by performing distance measurement and angle measurement using the wireless signal received by the receiver 10. The determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the three-dimensional position of the wireless communication device 4 calculated by the calculation unit 12. When the determination unit 13 determines that the wireless communication device 4 is located in the determination area, the communication unit 14 transmits the identification information transmitted from the wireless communication device 4 to the entry and exit management device 5.

[0072] According to such a structure, it is not necessary to set up the receiver 10 in a manner that surrounds the entire boundary of the management area, so it is easier to manage the new installation, relocation, and adjustment of the determination area. In addition, since it is determined whether the wireless communication device 4 is located in the determination area based on the three-dimensional position calculated based on the wireless signal, it is easy to adjust the range and shape of the determination area. Therefore, even if it is necessary to adjust the determination area according to the operation of the management area, it can be easily adjusted by setting the passage determination device 6. In addition, it is sufficient to set the passage determination device 6 at one position on the boundary of the management area, so it is possible to set the determination area more simply regardless of the environment of the installation place. In addition, the user can perform authentication in a hands-free manner by moving into the determination area with the wireless communication device 4, so the convenience of the user can be further improved.

[0073] The determination area is, for example, a columnar area with the vertical direction as the axial direction. At this time, the determination unit 13 determines whether the wireless communication device 4 is located within the determination area based on the position of the wireless communication device 4 in the horizontal plane.

[0074] The determination area is, for example, a cylindrical area with the vertical direction as the axis and the axis passing through the receiver 10. In this case, the determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the horizontal distance from the axis of the cylindrical area.

[0075] In addition, the determination area is, for example, a cylindrical area with a vertical direction as an axial direction, the axis passing through the receiver 10, and a sector centered on the axis as a bottom surface. In this case, the determination unit 13 determines whether the wireless communication device 4 is located in the determination area based on the azimuth angle of the position of the wireless communication device 4 around the axis of the cylindrical area and the horizontal distance of the wireless communication device 4 from the axis of the cylindrical area.

[0076] According to such a structure, the shape of the determination area does not depend on the height, so the authentication process is performed without being affected by the height of the wireless communication device 4. As a result, the range of the authentication process will not change due to the height of the wireless communication device 4 held by the user, so the convenience of the user can be further improved. In addition, in the setting of the determination area, there is no need to consider the height, so the management of the adjustment of the determination area becomes easier. In addition, in the case of using a cylindrical area as the determination area, only the radius in the horizontal direction can be set, so the setting of the determination area becomes simpler. In addition, it is possible to determine whether the wireless communication device 4 is located in the determination area only by comparing with the distance in the horizontal plane, so the determination process can be made lighter. In addition, in the case of using a cylindrical area with a fan-shaped bottom surface as the determination area, even if the movement route entering or exiting the management area is complicated, it is possible to easily set the determination area corresponding to the movement route. In addition, sometimes it is possible to determine that the wireless communication device 4 is located outside the determination area only by the azimuth as the angle measurement value, so the determination process can be made lighter.

[0077] In addition, in the entry and exit management system 1, a mandatory authentication distance may be preset. In this case, the calculation unit 12 calculates the straight-line distance between the receiver 10 and the wireless communication device 4 regardless of the angle measurement by using the wireless signal received by the receiver 10 to perform distance measurement. The determination unit 13 determines whether the straight-line distance calculated by the calculation unit 12 is shorter than the mandatory authentication distance. In the case where the determination unit 13 determines that the calculated straight-line distance is shorter than the mandatory authentication distance, the communication unit 14 transmits the identification information transmitted from the wireless communication device 4 to the authentication unit 8 of the entry and exit management device 5 regardless of whether the wireless communication device 4 is located in the determination area. In this case, the determination unit 13 may also omit the determination of whether the wireless communication device 4 is located in the determination area. For example, depending on the configuration of the passage determination device 6 and the surrounding environment, a blind spot where angle measurement is difficult may occur. In this case, the identification information required for the authentication process is transmitted to the authentication unit 8 of the entry and exit management device 5 by the wireless communication device 4 approaching to a distance closer than the mandatory authentication distance, thereby further improving the convenience of the user.

[0078] In addition, the passage determination device 6 may not be installed on the wall surface. For example, the passage determination device 6 may be installed on the ceiling of a space adjacent to the management area. In this case, the passage determination device 6 rotates the coordinate system as if it were installed on the wall surface, and can perform processing such as setting the determination area and determining entry into the determination area in the same manner as when it is installed on the wall surface. In addition, the passage determination device 6 may be installed on a pole erected near a security door, for example.

[0079] In addition, the entry and exit management system 1 may also manage the passage of multiple management areas in the facility. The entry and exit management system 1 may also include multiple passage determination devices 6. In the entry and exit management system 1, multiple passage determination devices 6 corresponding to multiple entrances and exits of a single management area may be provided, for example.

[0080] In addition, in the entry and exit management system 1, part or all of the functions of the entry and exit management device 5 may be mounted in the passage determination device 6. Part of the functions of the passage determination device 6 may be mounted in the entry and exit management device 5.

[0081] Next, use Figure 8 An example of the hardware configuration of the entry and exit management system 1 will be described.

[0082] Figure 8 This is a hardware configuration diagram of the main parts of the entry and exit management system 1 according to the first embodiment.

[0083] Each function of the entry and exit management system 1 can be realized by a processing circuit. The processing circuit includes at least one processor 100a and at least one memory 100b. The processing circuit may also include at least one dedicated hardware 200 together with or in place of the processor 100a and the memory 100b. The processing circuit is, for example, mounted on a device or apparatus constituting the entry and exit management system 1.

[0084] When the processing circuit includes a processor 100a and a memory 100b, each function of the entry and exit management system 1 is implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is described as a program. The program is stored in the memory 100b. The processor 100a implements each function of the entry and exit management system 1 by reading and executing the program stored in the memory 100b. The program that implements each function of the entry and exit management system 1 may also be a software package including a plurality of software that are applied to a plurality of computers, etc.

[0085] The processor 100a is also called a CPU (Central Processing Unit), a processing device, a computing device, a microprocessor, a microcomputer, or a DSP. The memory 100 is composed of, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM.

[0086] When the processing circuit has dedicated hardware 200, the processing circuit may be implemented by, for example, a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0087] Each function of the access management system 1 can be implemented by a processing circuit separately. Alternatively, each function of the access management system 1 can also be implemented by a processing circuit in a unified manner. Regarding each function of the access management system 1, a part can also be implemented by the dedicated hardware 200, and the other part can be implemented by software or firmware. In this way, the processing circuit implements each function of the access management system 1 through the dedicated hardware 200, software, firmware, or a combination thereof.

[0088] Implementation method 2.

[0089] In Embodiment 2, the differences from the example disclosed in Embodiment 1 are described in particular detail. With regard to features not described in Embodiment 2, any features of the example disclosed in Embodiment 1 can be adopted.

[0090] Fig. 9 This is a diagram showing an example of a determination area set in the entry and exit management system 1 according to the second embodiment.

[0091] The determination area includes a plurality of internal areas. Each internal area is pre-set in the storage unit 11, for example, based on the range of a three-dimensional position. In this example, the determination area includes an unlock determination area and an entry / exit determination area as internal areas. The entire determination area is, for example, a rectangular parallelepiped area outside the management area. The determination area includes the entrance and exit of the management area in the interior or at the boundary. The entry / exit determination area is an area leading to the management area. The entry / exit determination area includes the entrance and exit of the management area at the boundary. The entry / exit determination area is, for example, set as a rectangular parallelepiped area. The unlock determination area is set to surround the entry / exit determination area outside the management area. The unlock determination area is set to the area after removing the entry / exit determination area from the entire determination area. The unlock determination area faces the outside of the management area in the horizontal direction and does not face the inside of the management area. The unlock determination area is an example of the first area. The entry / exit determination area faces the inside of the management area in the horizontal direction and does not face the outside of the management area. The entry / exit determination area is an example of the second area.

[0092] The determination unit 13 determines the movement history of the user who moves with the wireless communication device 4 in a plurality of internal areas and outside the determination area. For example, the user who wants to enter the management area passes in the order of outside the determination area, unlocked determination area, in-out determination area, and outside the determination area. Therefore, in the case where the wireless communication device 4 enters the unlocked determination area from outside the determination area, and the wireless communication device 4 exits from the in-out determination area to outside the determination area, the determination unit 13 determines the movement history of the user who passes with the wireless communication device 4 as the user entering the management area. In addition, for example, the user who exits the management area passes in the order of outside the determination area, in-out determination area, unlocked determination area, and outside the determination area. Therefore, in the case where the wireless communication device 4 enters the in-out determination area from outside the determination area, and the wireless communication device 4 exits from the unlocked determination area to outside the determination area, the determination unit 13 determines the movement history of the user who passes with the wireless communication device 4 as the user exiting the management area. In addition, for example, the user who does not enter the management area but only passes by the periphery of the management area passes in the order of outside the determination area, unlocked determination area, and outside the determination area. Therefore, when the wireless communication device 4 enters the unlocked determination area from outside the determination area, and the wireless communication device 4 exits the unlocked determination area to outside the determination area, the determination unit 13 determines the movement history of the user traveling with the wireless communication device 4 as the user passing by without entering the management area.

[0093] The communication unit 14 transmits the movement history determined by the determination unit 13 for the user to the entry and exit management device 5 in association with the identification information transmitted from the wireless communication device that moves with the user.

[0094] The entry and exit management device 5 stores the identification information together with the movement history received from the passage determination device 6. Thus, the identification information about the user and the entry and exit relative to the management area are managed. At this time, the entry and exit management device 5 may store the movement history when the received movement history is determined to be a passing movement history, or may not store the movement history. In addition, the entry and exit management device 5 may also use the movement history received from the passage determination device 6 for the locking management of the electronic lock 2. For example, when the received movement history is determined to be a movement history of entering or exiting the area, the lock control unit 9 outputs an instruction to lock the electronic lock 2 after the door 3 opened when the user enters or exits the area is closed. In addition, when the received movement history is determined to be a passing movement history, the lock control unit 9 outputs an instruction to lock the electronic lock 2 before the door 3 is opened. At this time, the lock control unit 9 quickly outputs the locking instruction to the electronic lock 2 after receiving the movement history. According to the locking instruction from the lock control unit 9, the electronic lock 2 is locked in the door 3. Since the electronic lock 2 is locked quickly after the user passes by, the security in the managed area is further improved.

[0095] In addition, the inner area included in the determination area is not limited to a rectangular parallelepiped shape, but may be a columnar area with the vertical direction as the axis, a spherical area, or an area of ​​other shapes.
