[Diagram 2] 4 is a state transition table showing an example of an operation of the entrance / exit control system according to the first embodiment. [Diagram 3] 1 is a hardware configuration diagram of a main part of an entrance / exit management system according to a first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The embodiments for carrying out the subject of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. Note that the subject of the present disclosure is not limited to the following embodiments, and any component of the embodiment may be modified or omitted within the scope of the gist of the present disclosure.

[0013] Embodiment 1 FIG. 1 is a configuration diagram of an entrance / exit management system 1 according to the first embodiment.

[0014] The entrance / exit control system 1 is applied to a facility. The facility may be, for example, an indoor facility, an outdoor facility, or a facility that is a combination of these. The facility may consist of, for example, one or more buildings. The facility may 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 a facility. The entrance / exit control system 1 is a system that manages the entrance and exit of users to the management area.

[0015] In the access control system 1 of this example, the door 2 is provided at an entrance on the boundary of the managed area. The boundary of the managed area may include boundary areas such as the space on the periphery of the managed area and the space adjacent to the managed area. The door 2 is provided, for example, at the entrance of a building or an entrance to a room inside the building. In the access control system 1, instead of or together with the door 2, a security gate or the like may be provided at the entrance on the boundary of the managed area.

[0016] A user of the entrance / exit control system 1 who passes through the boundary of the management area passes through the facility while carrying, for example, a wireless communication device 3. A user who can pass through the boundary of the management area is, for example, a person or an autonomous mobile object that is permitted to enter and exit the management area. The wireless communication device 3 corresponds to, for example, a user who carries the wireless communication device 3. The wireless communication device 3 moves through the facility together with the corresponding user. The wireless communication device 3 may be, for example, a portable general-purpose information processing device such as a smartphone carried by the user or a smartwatch worn by the user, or may be a dedicated device of the entrance / exit control system 1 such as a wireless tag carried by the user. The wireless communication device 3 may be, for example, a wireless communication module built into the autonomous mobile object when the user is an autonomous mobile object. The wireless communication device 3 is equipped with a function for communicating wireless signals. The wireless communication device 3 stores identification information that identifies itself or identification information that identifies a user who passes with itself. The identification information is, for example, a unique ID (IDentifier) ​​given to the wireless communication device 3 or the user in the entrance / exit control system 1. The wireless communication device 3 transmits a wireless signal including the stored identification information. The wireless signal is, for example, a signal of UWB (Ultra Wide Band) or other standard.

[0017] The entrance / exit control system 1 includes one or more passage determination devices 4 and an entrance / exit management device 5. Each of the passage determination devices 4 and the entrance / exit management devices 5 is connected so as to be able to communicate with each other 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 line network.

[0018] Each passage determination device 4 is provided at the boundary of the managed area. In this example, the entrance / exit control system 1 is provided with two passage determination devices 4 at the entrances / exits of the managed area. One passage determination device 4 is provided adjacent to the entrance / exit on the outside of the managed area, on the wall surface separating the inside and outside of the managed area. The other passage determination device 4 is provided adjacent to the entrance / exit on the inside of the managed area, on the wall surface. Each passage determination device 4 is, for example, a UWB anchor. Each passage determination device 4 includes a receiver 7, a memory unit 8, a calculation unit 9, a determination unit 10, and a communication unit 11.

[0019] The receiver 7 is built into the passage determination device 4. The receiver 7 has a function of receiving a wireless signal transmitted by the wireless communication device 3. A single receiver 7 is provided at one location on the boundary of the management area as an internal device of the passage determination device 4. The receiver 7 includes one or more antennas. In this example, the receiver 7 includes multiple antennas.

[0020] The memory unit 8 is a part that has a function of storing information. The memory unit 8 stores, for example, information on a judgment area. The judgment area is a pre-set area for judging whether the passage of a user has been detected. The judgment area is set, for example, for an entrance / exit of a management area. In this example, the judgment area is a three-dimensional area. The judgment area is, for example, an area that leads to an entrance / exit of a management area to which the passage judgment device 4 is provided adjacent. The judgment area is set, for example, by a relative position based on the passage judgment device 4. The shape of the judgment area may be set, for example, by selecting from a plurality of types of shapes.

[0021] The judgment area may include a plurality of areas. In this example, the memory unit 8 of the passage judgment device 4 provided outside the management area stores information on the outer area and the outer inner area as information on the judgment area. Also, the memory unit 8 of the passage judgment device 4 provided inside the management area stores information on the inner area and the inner inner area as information on the judgment area. The outer area is an area surrounding an entrance outside the management area. The outer inner area is an area that is included in the outer area outside the management area and faces the entrance. The inner area is an area that surrounds an entrance inside the management area. The inner inner area is an area that is included in the inner area inside the management area and faces the entrance. 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, for example, to a columnar shape with the vertical direction as the axial direction. The shape of each area may be set, for example, to a rectangular parallelepiped, that is, a quadrangular column with a rectangular bottom. The shape of each area may be set, for example, to a columnar shape with a circular or sector-shaped bottom. The shape of each area may be set to, for example, a sphere or a hemisphere. 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, for example, about 2 m to 4 m. The width or depth of the outer inner area and the inner inner area is set to, for example, about 1 m.

[0022] Here, one of the outside and inside of the management area is an example of a first side of the entrance / exit. The other of the outside and inside of the management area is an example of a second side of the entrance / exit. Of the outside area and the inside area, the area set on the first side is an example of a first area. Of the outside area and the inside area, the area set on the second side is an example of a second area. Of the outside internal area and the inside internal area, the area set on the first side is an example of a first internal area. Of the outside internal area and the inside internal area, the area set on the second side is an example of a second internal area.

[0023] 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, by measuring distance and angle using the wireless signal received by the receiver 7. The three-dimensional position of the wireless communication device 3 is represented, for example, by relative coordinates based on the passage determination device 4. In this example, the three-dimensional position of the wireless communication device 3 is represented, for example, by coordinates (x, y, z) of a three-dimensional orthogonal coordinate system such as a Cartesian coordinate system. Note that the three-dimensional position of the wireless communication device 3 may also be represented, for example, by coordinates (r, θ, φ) of a three-dimensional orthogonal curvilinear coordinate system such as a polar coordinate system.

[0024] The calculation unit 9 acquires distance information between the wireless communication device 3 that has transmitted the wireless signal and the passage determination device 4 based on, for example, 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 acquire 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 a ToF method (ToF: Time of Flight). At this time, the calculation unit 9 may perform distance measurement using a one-way propagation time of the wireless signal by synchronizing with the wireless communication device 3, or may perform distance measurement using a propagation time of the wireless signal required for a round trip by transmitting and receiving a wireless signal to and from the wireless communication device 3. Here, the wireless signal transmitted by the wireless communication device 3 may be, for example, a response signal to a question signal transmitted by the passage determination device 4 to the vicinity of the entrance and exit of the management area by a wireless signal.

[0025] The calculation unit 9 acquires angle information based on the passage determination device 4 of the wireless communication device 3 that transmitted the wireless signal, for example, based on an angle measurement method using the wireless signal received by the receiver 7. The calculation unit 9 may acquire the arrival direction of the wireless signal from the wireless communication device 3, i.e., the angle information of the wireless communication device 3, by an angle measurement method such as the PDoA (Phase Difference of Arrival) method. The calculation unit 9 acquires the arrival direction of the wireless signal based on the phase difference of the wireless signal received by multiple antennas mounted on the receiver 7. Note that, for example, when the wireless communication device 3 simultaneously transmits multiple wireless signals from multiple antennas, the calculation unit 9 may acquire the arrival direction of the multiple wireless signals based on the phase difference between multiple wireless signals received by a single antenna mounted on the receiver 7.

[0026] The determination unit 10 is a part equipped with a function for determining whether or not the wireless communication device 3 is within a determination area. The determination unit 10 performs this determination by, for example, comparing the three-dimensional position of the wireless communication device 3 calculated by the calculation unit 9 with information on the determination area 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 or not the wireless communication device 3 is within the outer area or the outer inner area. Also, the determination unit 10 of the passage determination device 4 provided inside the management area determines whether or not the wireless communication device 3 is within the inner area or the inner inner area.

[0027] 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 entrance / exit management device 5 via the communication network 6 or the like. The communication unit 11 controls the transmission of the identification information to the entrance / exit management device 5 based on the determination result by the determination unit 10 as to whether the wireless communication device 3 is within 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 entrance / exit management device 5 while determining that the wireless communication device 3 is within the outer area or the outer inner area. Also, 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 entrance / exit management device 5 while determining that the wireless communication device 3 is within the inner area or the inner inner area. The communication unit 11 may transmit information on the three-dimensional position of the wireless communication device 3 together with the identification information to the entrance / exit management device 5. Also, the communication unit 11 may transmit 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 entrance / exit management device 5. The information specifying the judgment area includes, for example, information specifying whether the wireless communication device 3 is in the outer area, the outer inner area, the inner area, or the inner inner area. On the other hand, when it is determined that the wireless communication device 3 is not in any of the judgment areas, the communication unit 11 does not need to transmit the identification information transmitted from the wireless communication device 3 to the entrance / exit management device 5.

[0028] The entrance / exit management device 5 is a device that manages the entrance / exit of a user who attempts to pass through the boundary of a management area. The entrance / exit management of a user 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 entrance / exit management device 5 functions as a higher-level control device in the entrance / exit management system 1. The entrance / exit management device 5 is composed of, for example, one or more server computers. A part or all of the entrance / exit management device 5 may be provided in the facility or outside the facility. A part or all of the functions of the entrance / exit management device 5 may be implemented by processing or storage resources on a cloud service. The entrance / exit management device 5 includes a detection unit 12 and an alarm unit 13.

[0029] The detection unit 12 is a part that identifies and detects a user who is in any of the determination areas. The detection unit 12 identifies and detects a user who is in a determination area using the determination result by the determination unit 10 of the passage determination device 4. That is, the detection of a user by the detection unit 12 is performed based on a wireless signal transmitted by the wireless communication device 3. For example, the detection unit 12 identifies and detects a user who is in at least one of the outer area, the outer inner area, the inner area, and the inner inner area based on a wireless signal transmitted by the wireless communication device 3 that moves with the user. The detection unit 12 identifies the user based on identification information included in the wireless signal.

[0030] The alarm unit 13 is a part that performs processing to issue an alert to the user. The alarm unit 13 issues an alert to the user through an alarm, for example, by outputting information indicating the content of the alert to the alarm that issues the alert to the user. The alarm is, for example, mounted on the wireless communication device 3 that moves with the user. The alarm unit 13 specifies the alarm that outputs the content of the alert, for example, based on the identification information identified by the detection unit 12. The alarm is, for example, a speaker mounted on the wireless communication device 3 that issues an alert by voice. Alternatively, the alarm is, for example, a vibrator mounted on the wireless communication device 3 that issues an alert by vibration.

[0031] When the detection unit 12 detects an entering user who is in the outer area and an exiting user who is in the inner area, the notification unit 13 issues a first alarm to at least one of the entering and exiting users. The first alarm is, for example, an alarm that calls attention to wait for passage through the entrance and exit. After the first alarm is issued, the notification unit 13 issues a second alarm to at least one of the entering and exiting users when the detection unit 12 detects an entering user in the outer inner area and an exiting user in the inner inner area. The second alarm is an alarm with contents or manner different from the first alarm. For example, when the first alarm is an alarm by one of sound or vibration, the second alarm may be an alarm by the other of sound or vibration, or may be an alarm by both sound and vibration. In addition, the first alarm and the second alarm may both be alarms by sound. In this case, the sound of the first alarm and the sound of the second alarm may represent different contents from each other. In addition, the first alarm and the second alarm may both be alarms by vibration. In this case, the vibration for the first alarm and the vibration for the second alarm may have different vibration patterns.

[0032] The notification unit 13 changes at least one of the contents of the first alarm or the target person based on the information of the user identified by the detection unit 12. In this example, in the entrance / exit management system 1, a priority setting that allows some users to pass through the entrance / exit with priority is applied in advance. The priority setting is applied, for example, based on the identification information, affiliation, or attributes of the user. For example, in the entrance / exit management system 1, the priority setting is applied to a specific user who should be given priority based on the identification information of the user. For example, in the entrance / exit management system 1, the priority setting is applied to a user who is included in a specific organization or a group such as a VIP (Very Important Person) who should be given priority based on the affiliation of the user. For example, in the entrance / exit management system 1, the priority setting is applied to a user who uses a wheelchair based on the attribute of the user such as "wheelchair user". The notification unit 13 determines whether the detected user is set as a priority based on, for example, the identification information, affiliation, or attributes of the user. For example, when only one of the entering and leaving persons is set as a priority, the notification unit 13 issues a first alarm targeting users who are not set as a priority so as to give priority to the passage of the priority user. At this time, the notification unit 13 may change the content of the first alarm so as to notify one of the users who is the target of the first alarm that the other user is set as a priority. Note that in the entrance / exit management system 1, the priority may be set to a higher or lower level among the users who are set as a priority. At this time, the notification unit 13 changes at least one of the content of the first alarm or the target person so that the passage of the user to whom the priority setting with a higher priority is applied is given higher priority.

[0033] Next, an example of the operation of the entrance / exit control system 1 will be described with reference to FIG. FIG. 2 is a state transition table showing an example of the operation of the entrance / exit control system 1 according to the first embodiment.

[0034] The entrance / exit management device 5 transitions between a number 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 of the judgment areas. State B represents a state in which a departing person is detected in a judgment area inside the management area. State C represents a state in which an entering person is detected in a judgment area outside the management area. State D represents a state after a first alarm is issued targeting a departing person. State E represents a state after a first alarm is issued targeting an entering person. State F represents a state in which a departing person approaches door 2. State G represents a state in which an entering person approaches door 2. In the state transition table, the symbol "-" represents no action. In the state transition table, events with diagonal lines in each state represent events that do not occur in that state.

[0035] As a first example, we will explain the operation of the entry / exit control system 1 in the case where an intruder who is not set as a priority attempts to enter the controlled area from the outer area toward the entrance / exit, and an exiting person who is not set as a priority is detected in the inner area after the intruder is detected.

[0036] In the initial state, State A, the detection unit 12 detects an individual entering the outer area. After that, the state of the entrance / exit control system 1 transitions to State C.

[0037] In state C, the detection unit 12 detects a leaving person in the inner area. Based on the information of the entering and leaving persons identified by the detection unit 12, the alarm unit 13 determines whether the condition that priority is set for leaving persons and that priority is not set for entering persons is met. In this example, since priority is not applied to either entering or leaving persons, the alarm unit 13 targets leaving persons detected after entering persons and issues a first alarm. Leaving persons who receive the first alarm do not approach the entrance / exit, but wait until the door 2 opens and the entering person passes through. Entering persons who do not receive an alarm head toward the entrance / exit of the managed area. After that, the state of the access control system 1 transitions to state D.

[0038] In state D, the detection unit 12 detects an individual entering the outer internal area. After that, the state of the entrance / exit control system 1 transitions to state G.

[0039] When the state of the entrance / exit control system 1 is in state G, an intruder passes through the entrance from the outer internal area to enter the controlled area. After the intruder passes through the entrance and enters the controlled area, the detection unit 12 does not detect the intruder. When the detection unit 12 does not detect the intruder, the state of the entrance / exit control system 1 transitions to state B.

[0040] When the state of the entrance / exit control system 1 is in state B, a leaving person passes through the entrance from the inner area to leave the managed area. After the leaving person passes through the entrance and leaves the managed area, the detection unit 12 does not detect the leaving person. When the detection unit 12 does not detect the leaving person, the state of the entrance / exit control system 1 transitions to state A.

[0041] As a second example, we will explain the operation of the entry / exit control system 1 in a case where a non-priority entrant passes through an entrance / exit to enter the controlled area from an outer internal area, and a non-priority departing entrant is detected in the inner area after the entry entrant is detected.

[0042] In the initial state, State A, the detection unit 12 detects an individual entering the outer area. After that, the state of the entrance / exit control system 1 transitions to State C.

[0043] In state C, the detection unit 12 detects an entering person in the outer internal area. After that, the detection unit 12 detects a leaving person in the inner area. Based on the information of the entering person and the leaving person identified by the detection unit 12, the alarm unit 13 determines whether the condition that the leaving person is given priority and the entering person is not given priority is satisfied. In this example, since the priority setting is not applied to either the entering person or the leaving person, the alarm unit 13 targets the leaving person detected after the entering person and issues a first alarm. The leaving person who receives the first alarm does not approach the entrance, but waits until the door 2 opens and the entering person passes through. The entering person who does not receive the alarm continues to pass through the entrance. After that, the state of the entrance / exit control system 1 transitions to state D.

[0044] When the state of the entrance / exit control system 1 is in state D, an entering person passes through the entrance from the outer internal area and enters the controlled area. After the entering person passes through the entrance and enters the controlled area, the detection unit 12 does not detect the entering person. When the detection unit 12 does not detect the entering person, the alarm unit 13 targets the leaving person and issues an additional alarm notifying them that they are allowed to pass. The additional alarm is issued, for example, by sound or vibration via the wireless communication device 3 that moves with the leaving person. The state of the entrance / exit control system 1 then transitions to state B.

[0045] When the state of the entrance / exit control system 1 is in state B, a leaving person passes through the entrance from the inner area to leave the managed area. After the leaving person passes through the entrance and leaves the managed area, the detection unit 12 does not detect the leaving person. When the detection unit 12 does not detect the leaving person, the state of the entrance / exit control system 1 transitions to state A.

[0046] As a third example, we will explain the operation of the entry / exit control system 1 in a case where a non-priority entrant attempts to enter the controlled area from the outer area toward the entrance / exit, and a priority departing entrant is detected in the inner area after the detection of the entrant.

[0047] In the initial state, State A, the detection unit 12 detects an individual entering the outer area. After that, the state of the entrance / exit control system 1 transitions to State C.

[0048] In state C, the detection unit 12 detects a leaving person in the inner area. Based on the information of the entering and leaving persons identified by the detection unit 12, the alarm unit 13 determines whether the condition that priority is set for leaving persons and that priority is not set for entering persons is met. In this example, since priority is only applied to leaving persons, the alarm unit 13 issues a first alarm targeting entering persons so that leaving persons can be given priority. Entering persons who receive the first alarm do not approach the entrance / exit, but wait until the door 2 opens and the leaving person passes through. Leaving persons who do not receive an alarm head toward the entrance / exit of the managed area. After that, the state of the access control system 1 transitions to state E.

[0049] In state E, the detection unit 12 detects a person exiting the inner area. After that, the state of the entrance / exit control system 1 transitions to state F.

[0050] When the state of the entrance / exit control system 1 is in state F, a leaving person passes through the entrance from the inner internal area to leave the managed area. After the leaving person passes through the entrance and leaves the managed area, the detection unit 12 does not detect the leaving person. When the detection unit 12 does not detect the leaving person, the state of the entrance / exit control system 1 transitions to state C.

[0051] When the state of the entrance / exit control system 1 is state C, an intruder passes through the entrance from the outer internal area to enter the controlled area. After the intruder passes through the entrance and enters the controlled area, the detection unit 12 does not detect the intruder. When the detection unit 12 does not detect the intruder, the state of the entrance / exit control system 1 transitions to state A.

[0052] As a fourth example, we will explain the operation of the entry / exit control system 1 in a case where a first alarm is issued to a non-priority exiting person, and then both an entering person and an exiting person who are not priority attempt to pass through an entrance / exit.

[0053] In the initial state, State A, the detection unit 12 detects an individual entering the outer area. After that, the state of the entrance / exit control system 1 transitions to State C.

[0054] In state C, the detection unit 12 detects a departing person in the inner area. Based on the information of the entering and leaving persons identified by the detection unit 12, the notification unit 13 determines whether the condition that priority is given to leaving persons and that priority is not given to entering persons is satisfied. In this example, since priority is not applied to either entering or leaving persons, the notification unit 13 targets the leaving person detected after the entering person and issues a first alarm. Entering persons who have not received an alarm head toward the entrance / exit of the managed area. For example, if the alarm is not noticed, the leaving person heads toward the entrance / exit of the managed area without waiting, despite receiving the first alarm. After that, the state of the entrance / exit control system 1 transitions to state D.

[0055] In state D, the detection unit 12 detects an individual entering the outer internal area. After that, the state of the entrance / exit control system 1 transitions to state G.

[0056] In state G, the detection unit 12 detects a departing person in the inner internal area. In this way, when an entering person is detected in the outer internal area and a departing person is detected in the inner internal area, the alarm unit 13 issues a second alarm targeting both the entering and departing person. At this time, the alarm unit 13 may determine whether the second alarm has already been issued, and issue the second alarm if it has not been issued yet. The alarm unit 13 may continue to issue the second alarm until the condition in which an entering person is detected in the outer internal area and a departing person is detected in the inner internal area is resolved.

[0057] As a fifth example, we will explain the operation of the entry / exit control system 1 in a case where a user who is not set as a priority outside the managed area is passing through the outer area, passing directly in front of the entrance / exit, and after the detection of that user, a person who is not set as a priority and is leaving the area is detected in the inner area.

[0058] In the initial state, State A, the detection unit 12 detects a user who passes through the outer area as an entering person. After that, the state of the entrance / exit control system 1 transitions to State C.

[0059] In state C, the detection unit 12 detects a leaving person in the inner area. The alarm unit 13 determines whether the condition that priority is given to leaving persons and that priority is not given to entering persons is satisfied based on the information of the entering and leaving persons identified by the detection unit 12. In this example, since priority is not applied to either entering or leaving persons, the alarm unit 13 targets the leaving person detected after the entering person and issues a first alarm. The leaving person who receives the first alarm does not approach the entrance, but waits until the door 2 opens and the entering person passes through. The user who is considered to be an entering person continues to pass through the entrance by passing through the outer area. After that, the state of the entrance / exit control system 1 transitions to state D.

[0060] When the state of the entrance / exit control system 1 is in state D, after a user deemed to be an entrant passes through the entrance / exit and leaves the outer area, the detection unit 12 does not detect the user. When the detection unit 12 does not detect a user deemed to be an entrant, the notification unit 13 targets the departing person and issues an additional notification notifying them that they are allowed to pass. The additional notification is issued, for example, by sound or vibration via the wireless communication device 3 that moves with the departing person. After that, the state of the entrance / exit control system 1 transitions to state B.

[0061] When the state of the entrance / exit control system 1 is in state B, a leaving person passes through the entrance from the inner area to leave the managed area. After the leaving person passes through the entrance and leaves the managed area, the detection unit 12 does not detect the leaving person. When the detection unit 12 does not detect the leaving person, the state of the entrance / exit control system 1 transitions to state A.

[0062] Even if the order of entry and exit persons is reversed in the above example, the entrance / exit control system 1 operates in the same manner according to the state transition table of FIG.

[0063] As described above, the entrance / exit management system 1 according to the first embodiment includes a plurality of wireless communication devices 3 and an entrance / 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 for the corresponding user. The entrance / exit management device 5 includes a detection unit 12 and a notification unit 13. The detection unit 12 identifies and detects a user in any of the determination areas based on the wireless signal transmitted from the wireless communication device 3 using the identification information included in the wireless signal. The determination areas include an outer area surrounding the entrance / exit outside the entrance / exit of the management area, an outer inner area included in the outer area outside the entrance / exit and facing the entrance / exit, an inner area surrounding the entrance / exit inside the entrance / exit of the management area, and an inner inner area included in the inner area inside the entrance / exit and facing the entrance / exit. When the detection unit 12 detects a certain user a in the outer area and 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 internal area and the user b in the inner internal area after the first alarm is issued, the notification unit 13 issues a second alarm different from the first alarm to at least one of the users.

[0064] With this configuration, a two-stage alarm is issued to users passing on both sides of the entrance, further reducing the possibility of collisions between users. Also, since each user is identified by their identification information, the approach to and passage through the entrance can be determined more accurately by detection in the outer and inner areas facing the entrance. This allows the alarm to be issued at a more appropriate time.

[0065] Furthermore, when a user detected on one side of the entrance passes through without passing through the entrance after the first alarm is issued, the notification unit 13 issues an additional notification to notify a user on the other side of the entrance that they can pass through. This allows a user who has been waiting after receiving the first alarm to pass through the entrance when it is determined that another user has passed through the entrance. This reduces unnecessary waiting time for users, and improves user convenience.

[0066] Furthermore, the notification unit 13 changes at least one of the content and the target of the first warning based on the information of the user identified by the detection unit 12. This allows the warning to be issued in a more appropriate manner depending on the user passing by. The notification unit 13 may change the language of the first warning, for example, based on the information of the user.

[0067] Furthermore, when a user detected on one side of the entrance / exit is set as a priority and a user detected on the other side of the entrance / exit is not set as a priority, the notification unit 13 issues a first alarm targeting the user who is not set as a priority. This makes it possible to give priority to users who should be given priority based on the attributes and other information of the users passing through, thereby further improving convenience for users.

[0068] The alarm unit 13 issues an alert by sound emitted by a speaker mounted on the wireless communication device 3 that moves with the user identified by the detection unit 12. The alarm unit 13 issues an alert by vibration of a vibrator mounted on the wireless communication device 3 that moves with the user identified by the detection unit 12. This makes it easier to introduce the entrance / exit management system 1, as there is no need to install speakers around the entrance / exit. In addition, since the alert is issued through the wireless communication device 3 that the user himself / herself carries, the target of the alert becomes clearer. This makes it easier for the user to notice the alert.

[0069] In the entrance / exit control 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, in a case where multiple UWB anchors are provided on one side of an entrance / exit, the three-dimensional position of the wireless communication device 3 may be calculated using distance measurement information acquired by the multiple UWB anchors. In the entrance / exit control system 1, the three-dimensional position of the wireless communication device 3 may be calculated by other methods.

[0070] The passage determination device 4 does not have to be provided on a wall. For example, the passage determination device 4 may be provided on a ceiling of a space adjacent to the managed area. The passage determination device 4 may be provided on a pole erected near a security gate.

[0071] The entrance / exit control system 1 may also control the entrance / exit zones for multiple managed areas in a facility. In the entrance / exit control system 1, multiple passage determination devices 4 may be provided for a single managed area, for example, corresponding to multiple entrances / exits of the managed area.

[0072] In the entrance / exit management system 1, some or all of the functions of the entrance / exit management device 5 may be installed in the passage determination device 4. Some of the functions of the passage determination device 4 may be installed in the entrance / exit management device 5.

[0073] Next, an example of the hardware configuration of the entrance / exit control system 1 will be described with reference to FIG. FIG. 3 is a hardware configuration diagram of a main part of the entrance / exit control system 1 according to the first embodiment.

[0074] Each function of the entrance / exit control system 1 may 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 include at least one dedicated hardware 200 together with the processor 100a and the memory 100b, or as a substitute for them. The processing circuit is mounted on, for example, a device or apparatus that constitutes the entrance / exit control system 1.

[0075] When the processing circuit includes a processor 100a and a memory 100b, each function of the entrance / exit control system 1 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. The program is stored in the memory 100b. The processor 100a realizes each function of the entrance / exit control system 1 by reading and executing the program stored in the memory 100b. The program that realizes each function of the entrance / exit control system 1 may be a software package or the like including multiple software programs each applied to multiple computers or the like.

[0076] 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 non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM.

[0077] Where the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof.

[0078] Each function of the entrance / exit control system 1 can be realized by a processing circuit. Alternatively, each function of the entrance / exit control system 1 can be realized collectively by a processing circuit. Some of the functions of the entrance / exit control system 1 may be realized by dedicated hardware 200, and the other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the entrance / exit control system 1 by dedicated hardware 200, software, firmware, or a combination of these.
