[0001] The present disclosure relates to an entrance / exit management system, an entrance / exit management method, and an entrance / exit management program for managing the entrance / exit of users to a controlled area. [Background technology]

[0002] In a conventional entrance / exit management system, an antenna receives identification information via radio waves from a tag carried by a user and transmits it to a controller, and the controller performs authentication processing for the user. When authentication processing for a user is performed in two areas, radio waves of the same strength are output from each antenna corresponding to each area (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5880736 Summary of the Invention [Problem to be solved by the invention]

[0004] When using the technology described in Patent Document 1, by providing an antenna corresponding to the entrance area and an antenna corresponding to the facility area, it is possible to identify whether the user is in the entrance area or the facility area, and to determine the direction of travel of the user. In this case, it was necessary to adjust the radio wave range and the timing of radio wave output so that the radio waves output by each antenna would not interfere with each other.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an entrance / exit management system that can determine the direction of movement of users without taking into account interference of radio waves output by an antenna.

[0007] The entrance and exit management method according to the present disclosure includes a detection step of outputting radio waves that form an authentication area, a first wireless terminal and a second wireless terminal carried by a user entering the authentication area, receiving radio waves from the first wireless terminal and the second wireless terminal, and a detection step of detecting the radio wave output signals of the first wireless terminal and the second wireless terminal by a detection unit, and a determination step of, if there is a difference between the radio wave output signal of the first wireless terminal and the radio wave output signal of the second wireless terminal, by a determination step of a determination direction of travel of the user from the difference between the radio wave output signal of the first wireless terminal and the radio wave output signal of the second wireless terminal.

[0008] The entrance and exit management program of the present disclosure causes a computer to execute a detection step of outputting radio waves that form an authentication area, a first wireless terminal and a second wireless terminal carried by a user entering the authentication area, receiving radio waves from the first wireless terminal and the second wireless terminal, and a detection step of a detection unit detecting the radio wave output signals of the first wireless terminal and the second wireless terminal, and a determination step of a determination unit determining the direction of travel of the user from the difference between the radio wave output signal of the first wireless terminal and the radio wave output signal of the second wireless terminal if there is a difference between the radio wave output signal of the first wireless terminal and the radio wave output signal of the second wireless terminal.

[0011] Embodiment 1 The configuration of the vicinity of security gates 3a and 3b in the first embodiment will be described. Fig. 1 is a diagram showing the configuration of the vicinity of security gates 3a and 3b. In the present invention, passing from entrance 1 to facility 2, which is a controlled area, is referred to as "entering," and passing from facility 2 to entrance 1 is referred to as "exiting." Furthermore, entering and leaving a room are referred to as "entering and leaving." Furthermore, a person who is present in the vicinity of security gates 3a and 3b and who is about to enter or leave the room is referred to as a user 5.

[0012] In FIG. 1, a user 5 is present at an entrance 1 and is about to enter. The user 5 carries a tag 6, which is a first wireless terminal, and a tag 7, which is a second wireless terminal. In addition, a pair of security gates 3a, 3b are provided between the entrance 1 and the facility 2, connecting the entrance 1 and the facility 2. Here, the security gate provided on the left side as viewed from the entrance 1 side is referred to as security gate 3a, and the security gate provided on the right side as viewed from the entrance 1 side is referred to as security gate 3b. The security gate 3b has an antenna 4, which is a detection unit, and a monitor 12, which is a notification device that displays notification contents, on its upper surface. In addition, the security gate 3b has a built-in controller 8 that performs entry and exit management based on information received by the antenna 4.

[0013] The tags 6 and 7 are, for example, tags using RFID (Radio Frequency Identification), and will be described here as outputting radio waves. The tags 6 and 7 store identification information of the user 5 who carries the tags 6 and 7. The identification information is, for example, information on whether or not the user is allowed to enter and leave the facility 2. The user 5 carries the tag 6 at an arbitrary location on the left half of the user's body, and the tag 7 at an arbitrary location on the right half of the user's body. In the present invention, the distance A between the antenna 4 and the tag 6 and the distance B between the antenna 4 and the tag 7 are compared to determine the direction of travel of the user 5, so it is desirable that the tags 6 and 7 are carried at symmetrical locations on the user's body. The symmetrical locations do not necessarily have to be strictly symmetrical, and may be, for example, locations that are paired on the left and right sides of the user's body. For example, as shown in FIG. 1, the tag 6 may be worn on the left wrist of the user 5, and the tag 7 may be worn on the right wrist of the user 5. Of course, there is no particular limitation as long as the user 5 holds the tag 6 and the tag 7 in different positions, that is, as long as the positions are such that the distance A between the antenna 4 and the tag 6 and the distance B between the antenna 4 and the tag 7 are different. Note that the distance A between the antenna 4 and the tag 6 and the distance B between the antenna 4 and the tag 7 will hereinafter be referred to as distance information.

[0014] The antenna 4 forms an authentication area 13 by radio waves output from the antenna 4. As shown in FIG. 1, the authentication area 13 is formed to surround the security gates 3a and 3b. This is to receive radio waves from the tags 6 and 7 carried by the users 5 who are entering and leaving the entrance 1 and the facility 2. The antenna 4 uses, for example, RFID to acquire identification information of the users 5 carrying the tags 6 and 7 from the tags 6 and 7 present in the authentication area 13. Furthermore, the antenna 4 detects radio wave output signals of the tags 6 and 7 present in the authentication area 13. Specifically, the antenna 4 detects the value of RSSI (Received Signal Strength Indicator), which is the signal strength of the radio waves of the tags 6 and 7. When the signal strength is detected, the distances A and B are calculated from the strength, and distance information can be acquired.

[0015] The monitor 12 displays text to notify the user 5 that entry has been permitted, that exit has been permitted, or that entry / exit has not been permitted.

[0016] Next, the configuration of the entrance / exit management system in the first embodiment will be described. Fig. 2 is a configuration diagram of the entrance / exit management system. The entrance / exit management system has tags 6 and 7 carried by a user 5, an antenna 4, an authentication unit 9, a travel direction determination unit 10, a notification unit 11a, and a monitor 12. The functions of the authentication unit 9, the travel direction determination unit 10, and the notification unit 11a are realized by a controller 8.

[0017] The authentication unit 9 performs authentication processing on the identification information of the user 5 received from the antenna 4. The authentication processing is processing to determine whether or not the user 5 is permitted to enter and leave the facility 2. The authentication result is transmitted to the notification unit 11a.

[0018] The travel direction determination unit 10 receives the distance information from the antenna 4. Then, the distance A is compared with the distance B to determine the travel direction of the user 5. For example, as shown in FIG. 1, when a user 5 is about to enter the entrance 1, the distance A is longer than the distance B. At this time, the travel direction of the user 5 is determined to be the direction of entry. When a user 5 is about to leave the facility 2, the distance A is shorter than the distance B. At this time, the travel direction of the user 5 is determined to be the direction of exit. The determination result is transmitted to the notification unit 11a. Note that the distance information can only be acquired from the tags 6 and 7 that correspond to the entrance and exit management system. Therefore, when the tags 6 and 7 are not present within the authentication area 13, the travel direction determination unit 10 does not determine the travel direction of the user 5.

[0019] The notification unit 11a receives the authentication result of the authentication unit 9 and the judgment result of the travel direction judgment unit 10, and notifies the monitor 12 that the user 5 is permitted to enter, permitted to leave, or not permitted to enter or leave. FIG. 3 is a diagram showing the contents of the notification by the notification unit 11a. As shown in FIG. 3, when the authentication unit 9 authenticates that the user 5 is permitted to enter or leave the room, and the travel direction judgment unit 10 judges that the user 5 is passing in the direction of entering the room, the notification unit 11a notifies that the user 5 is permitted to enter or leave the room. Also, when the authentication unit 9 authenticates that the user 5 is permitted to enter or leave the room, and the travel direction judgment unit 10 judges that the user 5 is passing in the direction of leaving the room, the notification unit 11a notifies that the user 5 is permitted to leave the room. Also, when the authentication unit 9 authenticates that the user 5 is not permitted to enter or leave the facility 2, the notification unit 11a notifies that the user 5 is not permitted to enter or leave the facility 2.

[0020] Here, a description will be given of the hardware configuration of the controller 8 in the embodiment 1. Fig. 4 is a diagram showing the hardware configuration of the controller 8. The controller 8 is realized by a computer such as a personal computer or a microcontroller.

[0021] The controller 8 includes a processor 41 , a memory 42 , an interface 43 , and a secondary storage device 44 , which are connected to each other via a bus 40 .

[0022] The processor 41 is, for example, a CPU (Central Processing Unit). The processor 41 loads an operation program stored in the secondary storage device 44 into the memory 42 and executes the program, thereby implementing each function of the controller 8.

[0023] The memory 42 is a main storage device configured by, for example, a RAM (Random Access Memory). The memory 42 stores the program read by the processor 41 from the secondary storage device 44. The memory 42 also functions as a work memory when the processor 41 executes the program.

[0024] The interface 43 is an I / O (Input / Output) interface such as a serial port, a USB (Universal Serial Bus) port, a network interface, etc. The interface 43 receives input from the antenna 4 and outputs to the monitor 12.

[0025] The secondary storage device 44 is, for example, a flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The secondary storage device 44 stores various information necessary for the operation of the entrance and exit control system and programs executed by the processor 41.

[0026] Next, the operation of the entrance / exit control system in the first embodiment will be described. Fig. 5 is a flowchart showing the operation of the entrance / exit control system. Note that this flowchart assumes the operation when the antenna 4 is provided on the upper surface of the security gate 3b as shown in Fig. 1.

[0027] First, a user 5 approaches security gates 3a, 3b, and tags 6 and 7 carried by the user 5 are detected in the authentication area 13 (S1). At this time, the antenna 4 receives, for example, RFID from tags 6 and 7, identification information of the user 5 carrying the tags 6 and 7. Furthermore, the antenna 4 detects radio wave output signals of tags 6 and 7 present within the authentication area 13. Specifically, the antenna 4 detects the value of Received Signal Strength Indicator (RSSI), which is the signal strength of the radio waves from tags 6 and 7. When the signal strength is detected, distances A and B are calculated from the strength, and distance information is acquired (S2).

[0028] Next, the authentication unit 9 performs authentication processing on the identification information of the user 5 received from the antenna 4 (S3).

[0029] When the authentication unit 9 authenticates that the user 5 is permitted to enter and leave the facility 2 (YES in S3), it transmits the authentication result to the notification unit 11a. In addition, the travel direction determination unit 10 compares the distance A with the distance B based on the distance information received from the antenna 4, and determines the travel direction of the user 5 (S4).

[0030] When the authentication unit 9 authenticates that the user 5 is not permitted to enter or leave the facility 2 (NO in S3), it transmits the authentication result to the notification unit 11a. The notification unit 11a notifies the monitor 12 that the user 5 is not permitted to enter or leave the facility 2 (S6).

[0031] When the travel direction determination unit 10 determines that the distance A is longer than the distance B (YES in S4), the travel direction determination unit 10 transmits the determination result that the travel direction of the user 5 is the direction to enter the room to the notification unit 11a. The notification unit 11a notifies the monitor 12 that entry is permitted based on the authentication result of the authentication unit 9 and the determination result of the travel direction determination unit 10 (S5).

[0032] When the travel direction determination unit 10 determines that the distance A is shorter than the distance B (NO in S4), the travel direction determination unit 10 transmits the determination result that the travel direction of the user 5 is the direction to leave the room to the notification unit 11a. The notification unit 11a notifies the monitor 12 that leaving the room is permitted based on the authentication result of the authentication unit 9 and the determination result of the travel direction determination unit 10 (S7).

[0033] As described above, the entrance / exit management system in the first embodiment includes an antenna 4 that outputs radio waves forming an authentication area 13, and when tag 6, which is a first wireless terminal, and tag 7, which is a second wireless terminal, carried by user 5, enter the authentication area 13, receives radio waves from tag 6 and tag 7, and detects the radio wave output signals of tag 6 and tag 7, and a passage direction determination unit that, if there is a difference between the radio wave output signal of tag 6 and the radio wave output signal of tag 7, determines the passage direction of user 5 from the difference between the radio wave output signal of tag 6 and the radio wave output signal of tag 7. In this entrance / exit management system, since the authentication area 13 is formed using one antenna 4, there is no need to adjust the radio wave range or the timing of the radio wave output. Therefore, the passage direction of user 5 can be determined without considering interference of the radio waves output by antenna 4.

[0034] The antenna 4 may be configured to detect the value of RSSI, which is the signal strength of the radio waves of the tags 6 and 7, as the output signal of the radio waves of the tags 6 and 7, or may be configured to detect distance information from the value of RSSI, which is the signal strength of the radio waves of the tags 6 and 7. Furthermore, the communication between the antenna 4 and the tags 6 and 7 is not limited as long as it uses wireless communication. For example, communication may be performed using BLE (Bluetooth Low Energy) or UWB (Ultra Wide Band). Here, when BLE is used, the antenna 4 may be configured to detect the value of RSSI, which is the signal strength of the radio waves of the tags 6 and 7, or may be configured to detect distance information from the value of RSSI, which is the signal strength of the radio waves of the tags 6 and 7. Furthermore, when UWB is used, the antenna 4 may be configured to measure the distances A and B by calculating the time it takes for the output signals of the tags 6 and 7 to reach the antenna 4 (ToF (Time of Flight)) and detect distance information.

[0035] It is sufficient for antenna 4 to detect the radio wave output signals of tags 6 and 7, and another component may obtain distance information from the radio wave output signals and output the distance information to travel direction determination unit 10.

[0036] In addition, tags 6 and 7 store identification information indicating whether or not user 5 is permitted to enter and leave facility 2, which is a controlled area, and are equipped with an authentication unit 9 that performs authentication processing on the identification information when antenna 4 receives the identification information, thereby making it possible to perform authentication processing on user 5 while preventing radio wave interference with antenna 4.

[0037] Furthermore, by providing a notification unit 11a that notifies the authentication result obtained by the authentication unit 9 performing the authentication process, the user 5 can know the authentication result by looking at the monitor 12. The notification unit 11a further notifies the user 5 of the travel direction determined by the travel direction determination unit 10, so that the user 5 can know by looking at the monitor 12 that he or she has been permitted to enter, that he or she has been permitted to leave, or that he or she has not been permitted to enter or leave the room.

[0038] The entrance / exit control system in the first embodiment is required to include at least the antenna 4 and the passage direction determination unit 10.

[0039] Furthermore, as long as an authentication area 13 can be formed to surround security gates 3a, 3b and radio waves can be received from tags 6 and 7 carried by users 5 attempting to enter or leave entrance 1 and facility 2, the location of antenna 4 is not limited.

[0040] The location where the controller 8 is installed is not limited to inside the security gate 3b. For example, the controller 8 may be built in an external PC, and may receive information from the antenna 4 via wireless communication, and may notify the monitor 12 via wireless communication.

[0041] It should be noted that the tags 6 and 7 only need to be carried by the user 5, and there are no limitations on where they are carried. For example, the tag 6 may be attached to the left shoe of the user 5, and the tag 7 may be attached to the right shoe of the user 5. Furthermore, if the installation location of the antenna and whether the tag 6 or the tag 7 is carried on the left or right side are determined in advance, the travel direction determination unit 10 can correctly determine the travel direction. Whether the tag 6 or the tag 7 is carried on the left or right side may be determined appropriately.

[0042] The notification device is not limited to the monitor 12. For example, it may be a speaker or a flapper provided in the security gates 3a and 3b. When a speaker is used, the notification result may be output by voice. When a flapper is used, the flapper may be in a closed state as the initial state, and may be opened when entry or exit is permitted, and may be kept closed when entry or exit is not permitted.

[0043] It is not necessary to provide the security gates 3a and 3b. If the security gates 3a and 3b are not provided, the costs of installation can be reduced and the direction of travel of the user 5 can be determined and the authentication process can be performed. In this case, a speaker may be used as a notification device to notify the notification result by voice.

[0044] Embodiment 2 The configuration of the periphery of security gates 3a, 3b in embodiment 2 will be described. Fig. 6 is a diagram showing the configuration of the periphery of security gates 3a, 3b. The entrance / exit management system in embodiment 2 differs from embodiment 1 in that a left-ear wireless earphone 14, which is a first wearable speaker, is used as a first wireless terminal and notification device, and a right-ear wireless earphone 15, which is a second wearable speaker, is used as a second wireless terminal and notification device. Note that parts that are the same as or equivalent to those in embodiment 1 are given the same reference numerals and descriptions thereof will be omitted.

[0045] 6, a user 5 about to enter is present at the entrance 1. The user 5 is wearing a left-ear wireless earphone 14 on his left ear, and a right-ear wireless earphone 15 on his right ear.

[0046] The left-ear wireless earphone 14 and the right-ear wireless earphone 15 communicate with each other using, for example, the antenna 4 and an RFID. The left-ear wireless earphone 14 and the right-ear wireless earphone 15 store identification information of the user 5 who owns the left-ear wireless earphone 14 and the right-ear wireless earphone 15. Furthermore, the left-ear wireless earphone 14 and the right-ear wireless earphone 15 output sound to notify the user 5 that entry has been permitted, that exit has been permitted, or that entry and exit has not been permitted.

[0047] Next, the configuration of the entrance / exit management system in the second embodiment will be described. Fig. 7 is a configuration diagram of the entrance / exit management system. The entrance / exit management system includes a left-ear wireless earphone 14 and a right-ear wireless earphone 15 worn by a user 5, an antenna 4, an authentication unit 9, a travel direction determination unit 10, and a notification unit 11b.

[0048] The notification unit 11b receives information determined by the authentication unit 9 and information determined by the travel direction determination unit 10, and notifies the left ear wireless earphone 14 and the right ear wireless earphone 15 that the user 5 has been permitted to enter the room, permitted to leave the room, or not permitted to leave the room.

[0049] Next, a description will be given of the operation of the entrance / exit management system in the embodiment 2. Fig. 8 is a flowchart showing the operation of the entrance / exit management system.

[0050] First, a user 5 approaches security gates 3a and 3b, and the left-ear wireless earphone 14 and right-ear wireless earphone 15 carried by the user 5 are detected in the authentication area 13 (S11). Operations in S2 and S3 are the same as those in the first embodiment, and therefore will not be described.

[0051] When the authentication unit 9 authenticates that the user 5 is permitted to enter and leave the facility 2 (YES in S3), it transmits the authentication result to the notification unit 11b. Furthermore, the travel direction determination unit 10 compares the distance A' with the distance B' based on the distance information received from the antenna 4, and determines the travel direction of the user 5. Here, the distance A' is the distance between the left-ear wireless earphone 14 and the antenna 4, and the distance B' is the distance between the right-ear wireless earphone 15 and the antenna 4 (S14).

[0052] When the authentication unit 9 authenticates that the user 5 is not permitted to enter or leave the facility 2 (NO in S3), it transmits the authentication result to the notification unit 11b. The notification unit 11b notifies the left-ear wireless earphone 14 and the right-ear wireless earphone 15 that the user 5 is not permitted to enter or leave the facility 2 (S16).

[0053] When the travel direction determination unit 10 determines that the distance A' is longer than the distance B' (YES in S14), the travel direction determination unit 10 transmits the determination result that the travel direction of the user 5 is the direction to enter the room to the notification unit 11b. The notification unit 11b notifies the monitor 12 that entry is permitted based on the authentication result of the authentication unit 9 and the determination of the travel direction determination unit 10 (S15).

[0054] When the travel direction determination unit 10 determines that the distance A' is shorter than the distance B' (NO in S14), the travel direction determination unit 10 transmits the determination result that the travel direction of the user 5 is the direction to leave the room to the notification unit 11b. The notification unit 11b notifies the monitor 12 that leaving the room is permitted based on the authentication result of the authentication unit 9 and the determination of the travel direction determination unit 10 (S17).

[0055] As described above, in the entry / exit management system of embodiment 2, the first wireless terminal is a first wearable speaker worn on one ear of the user, and the second wireless terminal is a second wearable speaker worn on the other ear of the user, so that the position of the wireless terminal carried by user 5 is determined and the direction of travel of user 5 can be determined more accurately.

[0056] The left-ear wireless earphone 14 and the right-ear wireless earphone 15 may have different shapes on the left and right sides, or may have the same shape on the left and right sides. When using wireless earphones with the same shape on the left and right sides, the wireless earphones may be equipped with an identification unit that identifies the shapes of the left and right ear holes, and the antenna 4 may receive information on which ear (left or right) the wireless earphone is worn on by the user 5, thereby determining the left-ear wireless earphone 14 and the right-ear wireless earphone 15. This allows the position of the wireless terminal carried by the user 5 to be determined while the pair of wireless earphones is worn without being aware of which is left or right, and the direction in which the user 5 is moving can be determined more accurately.

[0057] The wearable speaker is not limited to a wireless earphone, but may be, for example, a headphone.

[0058] Furthermore, the notification unit 11b outputs the notification result as sound to at least one of the notification devices, the left-ear wireless earphone 14 and the right-ear wireless earphone 15. This makes it possible to directly notify the user 5 who should be notified, and the user 5 can enter and leave the room smoothly without worrying about notifications from other users 5.

[0059] The first wireless terminal and the device serving as the notification device and the second wireless terminal and the device serving as the notification device are not limited to the left-ear wireless earphone 14 and the right-ear wireless earphone 15. For example, the first wireless terminal may be built into the frame surrounding the left eye of the glasses, and the second wireless terminal may be built into the frame surrounding the right eye of the glasses, and the notification unit 11b may use AR (Augmented Reality) in the lenses of the glasses to display virtual information superimposed on the real scenery seen through the lenses, and display the notification result. This allows the position of the wireless terminal held by the user 5 to be determined, the direction of travel of the user 5 to be determined more accurately, and it is also possible to directly notify the user 5 to be notified, and the user 5 can smoothly enter and leave the room without worrying about notifications from other users 5.
