DETAILED DESCRIPTION

[0018] The embodiments for implementing the object of the present invention are described with reference to the accompanying drawings. In each figure, the same reference numerals are given to the same or equivalent parts, and repeated descriptions are appropriately simplified or omitted. In addition, the object of the present invention is not limited to the following embodiments, and any constituent elements of the embodiments can be deformed or omitted without departing from the scope of the present invention.

[0019] Implementation method 1.

[0020] Figure 1 This is a configuration diagram of the entry and exit management system 1 according to the first embodiment.

[0021] 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 that combines these facilities. 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 management area is an example of an area in the facility. The access management system 1 is a system that manages the entry and exit of users in the management area.

[0022] In the access management system 1 of this example, the door 2 is provided at the 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 of the peripheral part of the management area and the space adjacent to the management area. The door 2 is provided, for example, at the entrance hall of a building or 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 the door 2, or a security door or the like may be provided at the entrance and exit on the boundary of the management area together with the door 2.

[0023] A user of the entry and exit management system 1 passing through the boundary of the management area passes through the facility while holding a wireless communication device 3, for example. 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 and exit the management area. The wireless communication device 3 corresponds to, for example, a user holding the wireless communication device 3. The wireless communication device 3 moves within the facility as the corresponding user passes through. The wireless communication device 3 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 for the entry and exit management system 1 such as a wireless tag held by the user. For example, when the user is an autonomous mobile body, the wireless communication device 3 may also be a wireless communication module built into the autonomous mobile body. The wireless communication device 3 is equipped with a function of communicating wireless signals. The wireless communication device 3 stores identification information for identifying itself or identification information for identifying a user passing with itself. The identification information is, for example, a unique identifier (ID: IDentifier) ​​assigned to the wireless communication device 3 or the user in the entry and exit management system 1. The wireless communication device 3 transmits a wireless signal containing the stored identification information. The wireless signal is, for example, a signal of UWB (Ultra Wideband) or other standards.

[0024] The entry and exit management system 1 includes one or more passage determination devices 4 and an entry and exit management device 5. Each passage determination device 4 and the entry and exit management device 5 are connected in a manner that allows communication via a communication network 6. The communication network 6 may be, for example, a local network such as a LAN (Local Area Network) within a facility, or a wide area network such as the Internet or a telephone network.

[0025] Each passage determination device 4 is set at the boundary of the management area. In this example, the entry and exit management system 1 has two passage determination devices 4 for the entrance and exit of the management area. One passage determination device 4 is set on the wall separating the inside and outside of the management area so as to be adjacent to the entrance and exit on the outside of the management area. The other passage determination device 4 is set on the wall so as to be adjacent to the entrance and exit on the inside of the management area. Each passage determination device 4 is, for example, an ultra-wideband base station (Anchor). Each passage determination device 4 has a receiver 7, a storage unit 8, a calculation unit 9, a determination unit 10, and a communication unit 11.

[0026] The receiver 7 is built into the traffic determination device 4. The receiver 7 is equipped with a function of receiving a wireless signal transmitted by the wireless communication device 3. A single receiver 7 is installed at a place at the boundary of the management area as an internal device of the traffic determination device 4. The receiver 7 includes one or more antennas. In this example, the receiver 7 includes a plurality of antennas.

[0027] The storage unit 8 is a part equipped with a function of storing information. The storage unit 8 stores, for example, information of a determination area. The determination area is a pre-set area for determining whether or not the passage of a user is detected. The determination area is set, for example, for 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 connected to the entrance and exit of a management area, and the management area is set adjacent to the passage determination device 4. The determination area is set, for example, based on a relative position with respect to the passage determination device 4. The shape of the determination area can also be set, for example, by selecting from a plurality of shapes.

[0028] The determination area may also include multiple areas. In this example, the storage unit 8 of the traffic determination device 4 disposed outside the management area stores information of the outer area and the outer inner area as determination area information. In addition, the storage unit 8 of the traffic determination device 4 disposed inside the management area stores information of the inner area and the inner inner area as determination area information. The outer area is an area surrounding the entrance and exit outside the management area. The outer inner area is an area outside the management area that is included in the outer area and faces the entrance and exit. The inner area is an area surrounding the entrance and exit inside the management area. The inner inner area is an area inside the management area that is included in the inner area and faces the entrance and exit. In this example, the shape of each area including the outer area, the outer inner area, the inner area, and the inner inner area is set to be, for example, a columnar shape with the vertical direction as the axial direction. The shape of each area may also be set to be, for example, a rectangular parallelepiped, that is, a quadrangular prism with a rectangular bottom surface. The shape of each area may also be set to be, for example, a columnar shape with a circular or fan-shaped bottom surface. The shape of each area may be set to be, for example, a spherical shape or a hemispherical shape. In this example, the shape of each area is set to a rectangular parallelepiped. The width or depth of the outer area and the inner area is set to about 2m to 4m, for example. The width or depth of the outer inner area and the inner inner area is set to about 1m, for example.

[0029] Here, one of the outer side and the inner side of the management area is an example of the first side of the entrance and exit. The other of the outer side and the inner side of the management area is an example of the second side of the entrance and exit. The area set on the first side of the outer area and the inner area is an example of the first area. The area set on the second side of the outer area and the inner area is an example of the second area. The area set on the first side of the outer inner area and the inner inner area is an example of the first inner area. The area set on the second side of the outer inner area and the inner inner area is an example of the second inner area.

[0030] The calculation unit 9 is a part equipped with a function of calculating the three-dimensional position of the wireless communication device 3. The calculation unit 9 calculates the three-dimensional position of the wireless communication device 3 that has transmitted the wireless signal, for example, based on the distance measurement and angle measurement of the wireless signal received by the receiver 7. The three-dimensional position of the wireless communication device 3 is represented by, for example, relative coordinates based on the passage determination device 4. In this example, the three-dimensional position of the wireless communication device 3 is represented by, for example, coordinates (x, y, z) of a three-dimensional rectangular coordinate system such as a Cartesian coordinate system. In addition, the three-dimensional position of the wireless communication device 3 can also be represented by, for example, coordinates (r, θ, φ) of a three-dimensional rectangular curve coordinate system such as a polar coordinate system.

[0031] The calculation unit 9 obtains the distance information between the wireless communication device 3 that has transmitted the wireless signal and the passage determination device 4, for example, by a distance measurement method using the signal strength of the wireless signal received by the receiver 7. The signal strength is, for example, an RSSI value (RSSI: Received Signal Strength Indicator). Alternatively, the calculation unit 9 may obtain the distance information between the wireless communication device 3 that has transmitted the wireless signal and the passage determination device 4 by a distance measurement method such as the ToF method (ToF: Time of Flight). In this case, the calculation unit 9 may perform distance measurement by synchronizing with the wireless communication device 3 and using the one-way propagation time of the wireless signal, or may perform distance measurement by transmitting and receiving wireless signals with the wireless communication device 3 and using the round-trip propagation time of the wireless signal. Here, the wireless signal transmitted by the wireless communication device 3 may be, for example, a response signal to an inquiry signal transmitted by the passage determination device 4 to the periphery of the entrance and exit of the management area using a wireless signal.

[0032] The calculation unit 9 obtains angle information based on the passage determination device 4 of the wireless communication device 3 that has transmitted the wireless signal, for example, by using an angle measurement method using the wireless signal received by the receiver 7. The calculation unit 9 may also obtain the arrival direction of the wireless signal from the wireless communication device 3, that is, the angle information of the wireless communication device 3, by an angle measurement method such as the PDoA method (PDoA: Phase Difference of Arrival). The calculation unit 9 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 7. In addition, for example, when the wireless communication device 3 transmits multiple wireless signals simultaneously from multiple antennas, the calculation unit 9 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 7.

[0033] The determination unit 10 is a part equipped with a function of determining whether the wireless communication device 3 is located in the determination area. The determination unit 10 performs the determination by, for example, comparing the three-dimensional position of the wireless communication device 3 calculated by the calculation unit 9 with the determination area information stored in the storage unit 8. In this example, the determination unit 10 of the passage determination device 4 provided outside the management area determines whether the wireless communication device 3 is located in the outer area and the outer inner area. In addition, the determination unit 10 of the passage determination device 4 provided inside the management area determines whether the wireless communication device 3 is located in the inner area and the inner inner area.

[0034] The communication unit 11 is a part equipped with a function of transmitting the identification information transmitted from the wireless communication device 3 to the entry and exit management device 5 through the communication network 6 or the like. The communication unit 11 controls the transmission of the identification information to the entry and exit management device 5 based on the determination result of the determination unit 10 as to whether the wireless communication device 3 is located in the determination area. In this example, the communication unit 11 of the passage determination device 4 provided outside the management area continuously transmits the identification information transmitted from the wireless communication device 3 to the entry and exit management device 5 while determining that the wireless communication device 3 is located in the outer area or the outer inner area. In addition, the communication unit 11 of the passage determination device 4 provided inside the management area continuously transmits the identification information transmitted from the wireless communication device 3 to the entry and exit management device 5 while determining that the wireless communication device 3 is located in the inner area or the inner inner area. The communication unit 11 may also transmit the three-dimensional position information of the wireless communication device 3 together with the identification information to the entry and exit management device 5. In addition, the communication unit 11 may also transmit the information specifying the determination area determined to include the three-dimensional position of the wireless communication device 3 together with the identification information to the entry and exit management device 5. The information for determining the determination area includes, for example, information for determining in which area of ​​the outer area, the outer inner area, the inner area, and the inner inner area the wireless communication device 3 is located. On the other hand, when the communication unit 11 determines that the wireless communication device 3 is not within any of the determination areas, it is not necessary to transmit the identification information transmitted from the wireless communication device 3 to the entry and exit management device 5.

[0035] The entry and exit management device 5 is a device that manages the entry and exit of users who attempt to pass through the boundary of the management area. The management of the user's entry and exit is performed, for example, based on the identification information of the user or the identification information of the wireless communication device 3 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. The entry and exit management device 5 has a detection unit 12 and a notification unit 13.

[0036] The detection unit 12 is a part that identifies and detects a user located in any determination area. The detection unit 12 uses the determination result of the determination unit 10 of the passage determination device 4 to identify and detect a user located in the determination area. That is, the detection unit 12 detects the user based on the wireless signal transmitted by the wireless communication device 3. For example, the detection unit 12 identifies and detects a user located in at least one of the outer area, the outer inner area, the inner area, and the inner inner area based on the wireless signal transmitted by the wireless communication device 3 that moves with the user. The detection unit 12 identifies the user based on the identification information contained in the wireless signal.

[0037] The notification unit 13 is a part that performs the processing of the report to the user. The notification unit 13 outputs information indicating the content of the report to the notification device that notifies the user, and the notification is made to the user through the notification device. The notification device is, for example, mounted on the wireless communication device 3 that moves with the user. The notification unit 13 determines the notification device that outputs the content of the notification based on the identification information recognized by the detection unit 12. The notification device is, for example, a speaker mounted on the wireless communication device 3 that notifies by voice. Alternatively, the notification device is, for example, a vibrator mounted on the wireless communication device 3 that notifies by vibration.

[0038] When the detection unit 12 detects an entrant as a user located in the outer area and an exiter as a user located in the inner area, the notification unit 13 issues a first alarm to at least one of the entrant and the exiter. The first alarm is, for example, an alarm to draw attention to the person waiting for the entrance and exit. When the detection unit 12 detects an entrant located in the outer inner area and an exiter located in the inner inner area after issuing the first alarm, the notification unit 13 issues a second alarm to at least one of the entrant and the exiter. The second alarm is an alarm with different content or mode from the first alarm. For example, when the first alarm is an alarm made by one party using voice or vibration, the second alarm may be an alarm made by the other party using voice or vibration, or may be an alarm made by both parties using voice or vibration. In addition, the first alarm and the second alarm may both be alarms made by voice. In this case, the voice of the first alarm and the voice of the second alarm may also represent different contents. In addition, the first alarm and the second alarm may both be alarms made by vibration. In this case, the vibration of the first alarm and the vibration of the second alarm may also be different vibration patterns.

[0039] The notification unit 13 changes the content of the first alarm or at least one of the target persons based on the information of the user identified by the detection unit 12. In this example, in the entry and exit management system 1, priority settings that allow priority passage through the entrance and exit are applied in advance to some users. The priority settings are applied, for example, based on the identification information, affiliation, or attributes of the user. For example, in the entry and exit management system 1, priority settings are applied to the user based on the identification information of a specific user to be prioritized. For example, in the entry and exit management system 1, priority settings are applied to the user based on the affiliation of the user included in a specific organization or VIP (Very Important Person) group to be prioritized. For example, in the entry and exit management system 1, priority settings are applied to the user based on the attributes of the user who uses a wheelchair, such as a "wheelchair user". The notification unit 13 determines whether the detected user has been prioritized, for example, based on the identification information, affiliation, or attributes of the user. For example, when only one of the entry and exit is prioritized, the notification unit 13 issues the first alarm with the user who has not been prioritized as the target person, so that the passage of the user who has been prioritized is prioritized. At this time, the notification unit 13 may also change the content of the first alarm so that the user who is the subject of the first alarm is notified that the other user has been given priority. In addition, in the entry and exit management system 1, the priority level may be set between the users who have been given priority. At this time, the notification unit 13 changes the content of the first alarm or at least one of the subjects so that the user to whom the priority setting is applied with a stronger priority is given more priority to pass.

[0040] Next, use Figure 2 An operation example of the entry and exit management system 1 will be described.

[0041] Figure 2 This is a state transition table showing an operation example of the entry and exit management system 1 according to the first embodiment.

[0042] The entry and exit management device 5 transitions between a plurality of states including state A, state B, state C, state D, state E, state F, and state G. State A represents an initial state in which no user is detected in any determination area. State B represents a state in which an exiter is detected in a determination area inside the management area. State C represents a state in which an entryer is detected in a determination area outside the management area. State D represents a state after the first alarm is issued with the exiter as the target person. State E represents a state after the first alarm is issued with the entryer as the target person. State F represents a state in which the exiter has approached door 2. State G represents a state in which the entryer has approached door 2. In the state transition table, the sign "-" represents not taking any action. In the state transition table, events with diagonal lines in each state represent events that do not occur in that state.

[0043] As a first example, the operation of the entry and exit management system 1 will be described in the case where, when a non-priority entrant attempts to enter the management area from the outer area toward the entrance, after the entrant is detected, a non-priority entrant is detected in the inner area.

[0044] In the initial state A, the detection unit 12 detects an entrant in the outside area. Then, the state of the entry and exit management system 1 changes to the state C.

[0045] In state C, the detection unit 12 detects an exiter in the inner area. The notification unit 13 determines whether the condition that the exiter has been prioritized and the entrant has not been prioritized is satisfied based on the information of the entrant and the exiter identified by the detection unit 12. In this example, since the priority setting is not applied to either the entrant or the exiter, the notification unit 13 issues the first alarm with the exiter detected after the entrant as the target person. The exiter who receives the first alarm does not approach the entrance and exit but waits until the door 2 opens and the entrant passes. The entrant who does not receive the alarm goes to the entrance and exit of the management area. Then, the state of the entry and exit management system 1 changes to state D.

[0046] In the state D, the detection unit 12 detects an entrant in the outer inner area. Then, the state of the entry and exit management system 1 changes to the state D.

[0047] When the state of the entry and exit management system 1 is in state G, the entrant enters the management area from the outer inner area entrance. After the entrant enters the management area through the entrance, the detection unit 12 does not detect the entrant. When the detection unit 12 is set not to detect the entrant, the state of the entry and exit management system 1 changes to state B.

[0048] When the state of the entry and exit management system 1 is in state B, the exiter passes through the entrance and exit from the inner internal area and exits the management area. After the exiter passes through the entrance and exit and exits the management area, the detection unit 12 does not detect the exiter. When the detection unit 12 is set not to detect the exiter, the state of the entry and exit management system 1 changes to state A.

[0049] As a second example, the operation of the entry and exit management system 1 will be described in the case where a non-priority-set entrant passes through the gate to enter the management area from the outer inner area, and then a non-priority-set entrant is detected in the inner area.

[0050] In the initial state A, the detection unit 12 detects an entrant in the outside area. Then, the state of the entry and exit management system 1 changes to the state C.

[0051] In state C, the detection unit 12 detects an entrant in the outer inner area. Then, the detection unit 12 detects an exiter in the inner area. The notification unit 13 determines whether the condition that the exiter has been prioritized and the entrant has not been prioritized is satisfied based on the information of the entrant and the exiter identified by the detection unit 12. In this example, since the priority setting is not applied to either the entrant or the exiter, the notification unit 13 issues the first alarm with the exiter detected after the entrant as the target person. The exiter who receives the first alarm does not approach the entrance and exit but waits until the door 2 opens and the entrant passes through. The entrant who has not received the alarm continues to pass through the entrance and exit. Then, the state of the entry and exit management system 1 changes to state D.

[0052] When the state of the entry and exit management system 1 is in state D, the entrant enters the management area through the entrance and exit of the outer inner area. After the entrant passes through the entrance and exit and enters the management area, the detection unit 12 does not detect the entrant. When the detection unit 12 is set not to detect the entrant, the notification unit 13 sends an additional notification to the exiter as the target person to notify that the exiter can pass. The additional notification is notified by voice or vibration, etc., for example, through the wireless communication device 3 that moves with the exiter. Then, the state of the entry and exit management system 1 changes to state B.

[0053] When the state of the entry and exit management system 1 is in state B, the exiter passes through the entrance and exit from the inner internal area and exits the management area. After the exiter passes through the entrance and exit and exits the management area, the detection unit 12 does not detect the exiter. When the detection unit 12 is set not to detect the exiter, the state of the entry and exit management system 1 changes to state A.

[0054] As a third example, the operation of the entry and exit management system 1 will be described in the case where a non-prioritized entrant attempts to enter the management area from the outer area toward the entrance and exit, and a prioritized exiter is detected in the inner area after the entrant is detected.

[0055] In the initial state A, the detection unit 12 detects an entrant in the outside area. Then, the state of the entry and exit management system 1 changes to the state C.

[0056] In state C, the detection unit 12 detects an exiter in the inner area. The notification unit 13 determines whether the condition that the exiter has been prioritized and the entrant has not been prioritized is satisfied based on the information of the entrant and the exiter identified by the detection unit 12. In this example, since the priority setting is applied only to the exiter, the notification unit 13 issues the first alarm with the entrant as the target person so that the exiter can be prioritized. The entrant who receives the first alarm does not approach the entrance and exit but waits until the door 2 opens and the exiter passes. The exiter who does not receive the alarm goes to the entrance and exit of the management area. Then, the state of the entry and exit management system 1 changes to state E.

[0057] In the state E, the detection unit 12 detects the exiter in the inner inner area. Then, the state of the entry and exit management system 1 changes to the state F.

[0058] When the state of the entry and exit management system 1 is in state F, the exiter passes through the entrance and exit from the inner internal area and exits the management area. After the exiter passes through the entrance and exit and exits the management area, the detection unit 12 does not detect the exiter. When the detection unit 12 is set not to detect the exiter, the state of the entry and exit management system 1 changes to state C.

[0059] When the state of the entry and exit management system 1 is in state C, the entrant enters the management area through the entrance and exit from the outer inner area. After the entrant enters the management area through the entrance and exit, the detection unit 12 does not detect the entrant. When the detection unit 12 is set not to detect the entrant, the state of the entry and exit management system 1 changes to state A.

[0060] As a fourth example, the operation of the entry and exit management system 1 will be described in the case where both the entrant and the exiter who are not given priority try to pass through the entrance and exit after the first alarm is issued to the exiter who is not given priority.

[0061] In the initial state A, the detection unit 12 detects an entrant in the outside area. Then, the state of the entry and exit management system 1 changes to the state C.

[0062] In state C, the detection unit 12 detects an exiter in the inner area. The notification unit 13 determines whether the condition that the exiter has been prioritized and the entrant has not been prioritized is satisfied based on the information of the entrant and the exiter identified by the detection unit 12. In this example, since the priority setting is not applied to either the entrant or the exiter, the notification unit 13 issues the first alarm with the exiter detected after the entrant as the target person. The entrant who does not receive the alarm goes to the entrance and exit of the management area. For example, when the alarm is not noticed, the exiter does not wait and goes to the entrance and exit of the management area despite receiving the first alarm. Then, the state of the entry and exit management system 1 changes to state D.

[0063] In the state D, the detection unit 12 detects an entrant in the outer inner area. Then, the state of the entry and exit management system 1 changes to the state G.

[0064] In state G, the detection unit 12 detects an exiter in the inner inner area. In this way, when an entrant is detected in the outer inner area and an exiter is detected in the inner inner area, the notification unit 13 issues the second alarm with both the entrant and the exiter as the target persons. At this time, the notification unit 13 may determine whether the second alarm has been issued, and then issue the second alarm if it has not been issued. The notification unit 13 may continue to issue the second alarm until the conditions that the entrant is detected in the outer inner area and the exiter is detected in the inner inner area are eliminated.

[0065] As a fifth example, the operation of the entry and exit management system 1 is described in which a user who is not given priority is passing through the outer area of ​​the management area by passing in front of the entrance and exit, and after the user is detected, a person who is not given priority is detected leaving the inner area.

[0066] In the initial state A, the detection unit 12 detects a user who passes through the outside area as an intruder. Then, the state of the entry and exit management system 1 changes to the state C.

[0067] In state C, the detection unit 12 detects an exiter in the inner area. The notification unit 13 determines whether the condition that the exiter has been prioritized and the entrant has not been prioritized is satisfied based on the information of the entrant and the exiter identified by the detection unit 12. In this example, since the priority setting is not applied to either the entrant or the exiter, the notification unit 13 issues the first alarm with the exiter detected after the entrant as the target person. The exiter who receives the first alarm does not approach the entrance and exit but waits until the door 2 opens and the entrant passes through. The user who is regarded as an entrant continues to pass by the entrance and exit after passing the outer area. Then, the state of the entry and exit management system 1 changes to state D.

[0068] When the state of the entry and exit management system 1 is in state D, after the user regarded as an entry passes through the entrance and exit and exits the outer area, the detection unit 12 does not detect the user. When the detection unit 12 is set not to detect the user regarded as an entry, the notification unit 13 sends an additional notification notifying that the exiting user can pass through as the target person. The additional notification is notified by voice or vibration, for example, through the wireless communication device 3 moving with the exiting user. Then, the state of the entry and exit management system 1 changes to state B.

[0069] When the state of the entry and exit management system 1 is in state B, the exiter passes through the entrance and exit from the inner internal area and exits the management area. After the exiter passes through the entrance and exit and exits the management area, the detection unit 12 does not detect the exiter. When the detection unit 12 is set not to detect the exiter, the state of the entry and exit management system 1 changes to state A.

[0070] In addition, when the order of entry and exit of the above example is reversed, the entry and exit management system 1 also follows Figure 2 The state transition table operates in the same manner.

[0071] As described above, the entry and exit management system 1 of the first embodiment includes a plurality of wireless communication devices 3 and an entry and exit management device 5. Each wireless communication device 3 moves with the passage of a corresponding user. Each wireless communication device 3 transmits a wireless signal including identification information related to the corresponding user. The entry and exit management device 5 includes a detection unit 12 and a notification unit 13. The detection unit 12 identifies and detects a user located in an arbitrary determination area based on the wireless signal transmitted from the wireless communication device 3 using the identification information included in the wireless signal. The determination area includes an outer area, an outer inner area, an inner area, and an inner inner area, wherein the outer area surrounds the entrance and exit outside the entrance and exit of the management area, the outer inner area is included in the outer area outside the entrance and exit and faces the entrance and exit, the inner area surrounds the entrance and exit inside the entrance and exit of the management area, and the inner inner area is included in the inner area inside the entrance and exit and faces the entrance and exit. When the detection unit 12 detects a certain user a in the outer area and detects another user b in the inner area, the notification unit 13 issues a first alarm to at least one of the users. When the detection unit 12 detects the user a in the outer inner area and detects the user b in the inner inner area, the notification unit 13 issues a second alarm different from the first alarm to at least one of the users.

[0072] According to such a structure, since the alarm is issued to the users on both sides of the entrance and exit in two stages, the possibility of collision between users can be further suppressed. In addition, since each user is identified based on the identification information, the approach to the entrance and exit and the passage of the entrance and exit can be determined with higher accuracy by detecting in the outer inner area and the inner inner area facing the entrance and exit. As a result, the alarm can be issued at a more appropriate time.

[0073] Furthermore, when a user detected on one side of the entrance and exit passes by but does not pass through the entrance and exit after the first alarm is issued, the notification unit 13 issues an additional notification to the user on the other side of the entrance and exit to notify that the user can pass through. Thus, the user who has been waiting after receiving the first alarm can pass through the entrance and exit at the moment when it is determined that another user passes in front of the entrance and exit. Thus, the unnecessary waiting time of the user can be reduced, and the convenience of the user can be further improved.

[0074] Furthermore, the notification unit 13 changes at least one of the content of the first alarm or the target person according to the information of the user identified by the detection unit 12. Thus, the alarm is issued in a more appropriate method according to the user passing by. For example, the notification unit 13 may change the language of the first alarm according to the user information.

[0075] Furthermore, when the user detected on one side of the entrance and exit has been set as a priority and the user detected on the other side of the entrance and exit has not been set as a priority, the notification unit 13 issues the first alarm to the user on the side that has not been set as a priority user. Thus, the user who should be given priority can be given priority to pass according to information such as the attributes of the user to pass. Thus, the convenience of the user can be further improved.

[0076] In addition, the notification unit 13 makes a notification using a voice emitted by a speaker mounted on the wireless communication device 3 that moves with the user identified by the detection unit 12. In addition, the notification unit 13 makes a notification using the vibration of a vibrator mounted on the wireless communication device 3 that moves with the user identified by the detection unit 12. As a result, there is no need to set a speaker or the like around the entrance and exit, so it becomes easier to introduce the entry and exit management system 1. In addition, since the notification is made through the wireless communication device 3 held by the user himself, the target person of the alarm becomes clearer. As a result, the user is more likely to notice the alarm.

[0077] In addition, in the access management system 1, the three-dimensional position of the wireless communication device 3 may be calculated using only one of the distance measurement and the angle measurement. For example, when a plurality of ultra-wideband base stations are installed on one side of the entrance, the three-dimensional position of the wireless communication device 3 may be calculated based on the distance measurement information obtained by the plurality of ultra-wideband base stations. In the access management system 1, the three-dimensional position of the wireless communication device 3 may also be calculated by other methods.

[0078] In addition, the passage determination device 4 may not be installed on the wall surface. For example, the passage determination device 4 may be installed on the ceiling of a space adjacent to the management area. In addition, the passage determination device 4 may be installed on a pole erected near the security gate, for example.

[0079] In addition, the entry and exit management system 1 may manage entry and exit related to multiple management areas in a facility. In the entry and exit management system 1, multiple passage determination devices 4 corresponding to multiple entrances and exits of a management area may be provided for one management area.

[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 4 . Part of the functions of the passage determination device 4 may be mounted in the entry and exit management device 5 .

[0081] Next, use Figure 3 An example of the hardware configuration of the entry and exit management system 1 will be described.

[0082] Figure 3 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 access management system 1 can be realized by a processing circuit. The processing circuit has at least one processor 100a and at least one memory 100b. The processing circuit has a processor 100a, a memory 100b, and at least one dedicated hardware 200, or the processing circuit may have at least one dedicated hardware 200 instead of the processor 100a and the memory 100b. The processing circuit is, for example, mounted on a device or apparatus constituting the access 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, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The memory 100b is composed of a nonvolatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable Read Only Memory), or an EEPROM (Electrically Erasable Programmable Read Only Memory).

[0086] When the processing circuit has dedicated hardware 200, the processing circuit is implemented by, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination thereof.

[0087] Each function of the access management system 1 can be implemented separately by a processing circuit. Alternatively, each function of the access management system 1 can be implemented uniformly by a processing circuit. Regarding each function of the access management system 1, a part can also be implemented by 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 dedicated hardware 200, software, firmware or a combination thereof.
