[0003] [Patent Document 1] International Publication No. 2020 / 080314 Summary of the Invention [Problem to be solved by the invention]

[0004] In the authentication system of Patent Document 1 and the like, the authentication device may support wireless communication standards other than BLE, such as NFC (Near Field Communication), for user convenience. Here, a mobile device that performs BLE communication may also support NFC communication in addition to BLE communication. Furthermore, a user attempting to perform authentication using a mobile device that performs BLE communication may carry an IC card (IC: Integrated Circuit) that supports NFC communication in addition to the mobile device. The NFC communication module of the mobile device is activated by a wireless signal from the authentication device. In this case, the NFC communication module of the mobile device carried by the user may be unintentionally activated by communication with the authentication device, resulting in communication between the authentication device and the mobile device that the user did not intend. In such a case, wireless communication for authentication using the BLE communication of the mobile device may be interrupted, preventing smooth user authentication and causing delays in the user's passage.

[0011] [Figure 1] 1 is a configuration diagram of a traffic management system according to a first embodiment. [Figure 2] 4 is a flowchart showing an example of the operation of the traffic management system according to the first embodiment. [Figure 3] 1 is a hardware configuration diagram of a main part of a traffic control system according to a first embodiment. [Figure 4] FIG. 10 is a configuration diagram of a traffic management system according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] The following describes embodiments of the subject matter of the present disclosure with reference to the accompanying drawings. In each drawing, identical or corresponding parts are designated by the same reference numerals, and redundant explanations are appropriately simplified or omitted. Note that the subject matter of the present disclosure is not limited to the following embodiments, and any component of the embodiments 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 a traffic control system 1 according to the first embodiment.

[0014] The traffic management system 1 is applied to a facility 2. The facility 2 includes, for example, one or more buildings. The facility 2 may be part or all of a building. The facility 2 may include one or both of the outdoor and indoor portions of a building. The facility 2 may be, for example, a commercial facility, an office building, an accommodation facility, a residential facility, a public facility, or other facility, or a complex of these. The traffic management system 1 is a system that manages the passage of a passing object 3 passing through the facility 2. The passing object 3 may be, for example, a user of the facility 2 that is a person, or a mobile object that is equipment that moves through the facility 2. The mobile object may be, for example, an autonomous mobile object that moves autonomously within the facility 2. The mobile object may be, for example, a robot, a drone, an autonomous vehicle, or other mobile equipment.

[0015] The traffic management system 1 manages traffic through entrances 4 for entering and exiting an access control area. An access control area is an area that is managed so that at least one of entry and exit is restricted to authorized passing bodies 3. An access control area is, for example, an area inside or outside a building. The entrance 4 is provided at the boundary of the access control area. The entrance 4 is, for example, the entrance to a building or the entrance to a room inside a building. In this example, the entrance 4 is provided with a door equipped with an electric lock 5. The traffic management system 1, for example, unlocks the electric lock 5 to allow authorized passing bodies 3 to pass through the entrance 4, and locks the electric lock 5 to restrict unauthorized passing bodies 3 from passing through the entrance 4.

[0016] The passage management system 1 includes a reading device 6. The reading device 6 is provided adjacent to the passage entrance 4. The reading device 6 is installed, for example, on a wall surface adjacent to the passage entrance 4. The reading device 6 includes a first management communication unit 7, a second management communication unit 8, and a control unit 9.

[0017] The management first communication unit 7 is a part that is equipped with a function of wireless communication of a first method. The first method is, for example, a communication method such as a wireless PAN (Personal Area Network). The first method may be, for example, a communication method based on a communication standard such as IEEE 802.15.1, or its successor standard, related standard, compatible standard, or similar standard. The first method may be, for example, a communication method such as UWB (Ultra-Wide Band) communication. In this example, the management first communication unit 7 has a function of BLE communication as the first method.

[0018] In two devices that perform BLE communication, a central device corresponds to a parent device, and a peripheral device corresponds to a child device. Before one-to-one BLE communication is established, the peripheral device transmits an advertising signal, which is a wireless signal containing information that identifies the device. The advertising signal is an example of a first signal. The advertising signal contains information that identifies the peripheral device, such as the name, attributes, or address of the device. The advertising signal is transmitted by broadcasting without specifying a destination. The peripheral device transmits the advertising signal, for example, at a preset transmission cycle. After receiving the advertising signal from the peripheral device, the central device establishes one-to-one BLE communication with the peripheral device by pairing. In the traffic management system 1, the management first communication unit 7 functions as a central device of the first method.

[0019] The management second communication unit 8 is a part equipped with a function for wireless communication of a second method. The second method is, for example, a short-range wireless communication method such as NFC communication or UWB communication. In this example, the management second communication unit 8 has a function for NFC communication as the second method.

[0020] Two devices that perform NFC communication may be, for example, a driving device and a driven device. The driving device transmits a polling signal, which is a wireless signal that activates the driven device. The polling signal is an example of a second signal. The driving device transmits the polling signal, for example, at a preset transmission cycle. The driven device activates upon receiving the polling signal. Here, the driven device operates using power obtained from electromagnetic induction caused by the polling signal, which is an electromagnetic wave. In this case, the driven device does not need to have its own power source, such as a battery. When the driven device receives the polling signal and activates, it transmits information set in the driven device to the driving device via a wireless signal. Note that the driven device may also be a device with its own power source, such as a battery. In the traffic management system 1, the second management communication unit 8 functions as a driving device of the second method.

[0021] The control unit 9 is a part that has a function of controlling the operation of the reading device 6. The operation of the reading device 6 includes, for example, the wireless communication functions of the management first communication unit 7 and the management second communication unit 8.

[0022] The passage management system 1 determines whether the passing object 3 is permitted to pass through the passageway 4 based on the credential information of the passing object 3 received by the reading device 6 via one or both of the management first communication unit 7 and the management second communication unit 8. The credential information may be, for example, authentication information that authenticates the passing object 3 or authorization information indicating that the passing object 3 is permitted to pass. For example, when the passing object 3 can use wireless communication of the first method, the reading device 6 acquires the credential information of the passing object 3 via the management first communication unit 7. Also, when the passing object 3 can use wireless communication of the second method, the reading device 6 acquires the credential information of the passing object 3 via the management second communication unit 8. In this way, the passing object 3 can select to use either the first method, the second method, or both. The determination of whether the passing object 3 is permitted to pass based on the credential information may be made, for example, by the control unit 9 of the reading device 6 or by a device of the passage management system 1, such as the central management device 10. The central control device 10 may be, for example, a single computer device or multiple computers. Part or all of the central control device 10 may be located outside the facility 2. The central control device 10 is connected to a reader 6 so as to acquire credential information. The central control device 10 is connected to an electric lock 5 so as to allow an authorized pedestrian 3 to pass through the entrance 4.

[0023] The passing object 3 moves together with the portable device 11a. For example, the passing object 3, which is a person, carries the portable device 11a and moves together with the portable device 11a. The passing object 3, which is a device, may move together with the portable device 11a by attaching the portable device 11a to its exterior, or may move together with the portable device 11a by incorporating the portable device 11a. In this example, the passing object 3 carrying the portable device 11a also carries another portable device 11b. Here, when there is no particular distinction between the portable devices 11a and 11b, they may be simply referred to as the portable device 11. The portable device 11 is a portable device equipped with a wireless communication function. The portable device 11 may be a smartphone, a smartwatch, or other general-purpose information processing device, or may be an IC tag, an IC card, or other device dedicated to the passage management system 1. When the passing object 3 is a person, the portable device 11 may be owned by the passing object 3 or may be loaned to the passing object 3 by an administrator of the facility 2 or the like. The mobile device 11 may be a device within the system included in the traffic management system 1, or may be a device outside the system that cooperates with the traffic management system 1.

[0024] In this example, the mobile device 11a includes a first passage communication unit 12. The first passage communication unit 12 is a part equipped with a first type of wireless communication function. In this example, the first passage communication unit 12 has a BLE communication function as the first type. The mobile device 11a is, for example, a portable general-purpose information processing device such as a smartphone. In this example, the mobile device 11a holds qualification information of the passing object 3. In the passage management system 1, the first passage communication unit 12 functions as a peripheral device of the first type.

[0025] Furthermore, the portable device 11b includes a second passage communication unit 13. The second passage communication unit 13 is a unit equipped with a second type of wireless communication function. In this example, the second passage communication unit 13 has an NFC communication function as the second type. The portable device 11b is, for example, a portable device such as an IC card. In this example, the passing object 3 has the reader 6 read the qualification information by the portable device 11a. At this time, the portable device 11b does not store the qualification information of the passing object 3. The portable device 11b stores, for example, information used by the passing object 3 in other systems of the passage management system 1. The second passage communication unit 13 functions as a passive device of the second type.

[0026] Next, an example of the operation of the traffic control system 1 will be described with reference to FIG. FIG. 2 is a flowchart showing an example of the operation of the traffic management system 1 according to the first embodiment. In FIG. 2, an example of the operation of the reader 6 is shown.

[0027] The traveling object 3 carries both the mobile device 11a and the mobile device 11b and moves together with the mobile device 11a and the mobile device 11b. The traveling first communication unit 12 of the mobile device 11a is not paired with any other device. At this time, the traveling first communication unit 12, functioning as a peripheral device, transmits an advertising signal. Furthermore, the management second communication unit 8, functioning as a driving device, transmits a polling signal.

[0028] In step S1, the control unit 9 determines whether or not an advertising signal has been received from the first passage communication unit 12. When an advertising signal has not been received, the processing of the reading device 6 proceeds to step S2. On the other hand, when an advertising signal has been received, the processing of the reading device 6 proceeds to step S3.

[0029] In step S2, the management second communication unit 8 transmits a polling signal. If the management second communication unit 8 is already in a state to transmit a polling signal, the management second communication unit 8 continues transmitting the polling signal. After that, the processing of the reading device 6 proceeds to step S5.

[0030] In step S3, the management first communication unit 7 measures the signal strength of the received advertising signal. The signal strength is, for example, a received signal strength indicator (RSSI). The control unit 9 estimates the distance to the passing object 3 carrying the mobile device 11a equipped with the management first communication unit 7 based on the signal strength measured by the management first communication unit 7. The control unit 9 determines whether the passing object 3 has approached within a predetermined rest range from the passage entrance 4 based on the estimated distance. The rest range is, for example, a range where the distance from the reading device 6 adjacent to the passage entrance 4 is shorter than a predetermined distance. The rest range is, for example, a range where the distance from the reading device 6 is shorter than approximately 20 cm to 30 cm. The rest range may be set to another range. For example, the control unit 9 determines that the passing object 3 is approaching within the rest range when the distance from the passing object 3 is shorter than the predetermined distance. When the control unit 9 determines that the passing object 3 is not approaching within the rest range, the processing of the reading device 6 proceeds to step S2. When the control unit 9 determines that the passing object 3 is approaching within the rest range, the processing of the reading device 6 proceeds to step S4.

[0031] In step S4, the control unit 9 causes the management second communication unit 8 to suspend transmission of the polling signal. If the management second communication unit 8 has already suspended transmission of the polling signal, the control unit 9 continues to suspend transmission of the polling signal. The control unit 9 suspends transmission of the polling signal for, for example, a preset time. Thereafter, the processing of the reading device 6 proceeds to step S5.

[0032] In step S5, the control unit 9 determines whether the reading device 6 has acquired the qualification information of the passing object 3. For example, when the management first communication unit 7 establishes one-to-one BLE communication with the passing first communication unit 12, the control unit 9 determines whether the management first communication unit 7 has acquired the qualification information of the passing object 3. Note that while the management second communication unit 8 is transmitting a polling signal, the management second communication unit 8 may acquire the qualification information of another passing object that uses the second type of wireless communication in the passage management system 1 from the other passing object. If the reading device 6 has not acquired the qualification information, the processing of the reading device 6 proceeds to step S1. On the other hand, if the reading device 6 has acquired the qualification information, the processing of the reading device 6 proceeds to step S6.

[0033] In step S6, the control unit 9 provides the acquired qualification information to the central management unit 10. After that, the processing of the reading device 6 proceeds to step S1.

[0034] The central management unit 10 determines whether passage through the entrance 4 can be permitted based on the qualification information read by the reading unit 6. If passage can be permitted, the central management unit 10 unlocks the electric lock 5. On the other hand, if passage cannot be permitted, the central management unit 10 keeps the electric lock 5 locked.

[0035] The reading device 6 may function as a peripheral device and transmit an advertising signal in the first-method communication by the management first communication unit 7. At this time, the passage first communication unit 12 functions as a central device. The reading device 6 may be switchable between functioning as a peripheral device and functioning as a central device, for example, by settings. The reading device 6 may switch between functioning as a peripheral device and functioning as a central device, for example, at a preset time period. While the reading device 6 functions as a peripheral device of the first method, the management second communication unit 8 may suspend transmission of the polling signal of the second method.

[0036] As described above, the passage management system 1 according to the first embodiment includes a passage first communication unit 12, a passage second communication unit 13, and a reading device 6. The reading device 6 is provided adjacent to the passage entrance 4, where passage is managed, in a facility 2 through which a passing object 3 passes. The passage first communication unit 12 moves together with the passing object 3. The passage first communication unit 12 is equipped with a first-type wireless communication function. The passage first communication unit 12 transmits a first signal. The first signal is a first-type wireless signal that includes information for identifying the passing object 3. The passage second communication unit 13 moves together with the passing object 3. The passage second communication unit 13 is equipped with a second-type wireless communication function that is different from the first method. The passage second communication unit 13 is activated by a second signal, which is a second-type wireless signal. The reading device 6 includes a management first communication unit 7, a management second communication unit 8, and a control unit 9. The management first communication unit 7 is equipped with a first type of wireless communication function. After receiving a first signal from the passage first communication unit 12, the management first communication unit 7 receives qualification information that can determine whether or not passage through the passage entrance 4 is permitted through one-to-one communication with the passage first communication unit 12. The management second communication unit 8 is equipped with a second type of wireless communication function. The management second communication unit 8 transmits a second signal. When the control unit 9 detects the approach of a passing object 3 based on the management first communication unit 7 receiving the first signal from the passage first communication unit 12, it causes the management second communication unit 8 to pause transmission of the second signal.

[0037] In this example, the passage management system 1 can use multiple wireless communication standards, including a first method and a second method, for communicating credential information for user convenience. Here, the passing object 3 may possess a portable device 11a compatible with the first method for communicating credential information regarding passage through the passage entrance 4, as well as a portable device 11b compatible with the second method for use in other systems. In this case, wireless communication using multiple methods can be performed between the portable device 11 possessed by the passing object 3 and the reading device 6. Even in this case, the approach of the passing object 3 suspends transmission of the second signal of the second method, preventing the second passage communication unit 13 of the passing object 3 from activating. This prevents the second passage communication unit 13 from unintentionally activating. Unintentional transmission of information other than credential information from the second passage communication unit 13 is suppressed, so the reading device 6 does not receive unnecessary information. This reduces the information processing load on the reading device 6, preventing interference with the process of determining whether the passing object 3 is permitted to pass. Therefore, the passing object 3 can pass through the passageway 4 more smoothly. Note that the control unit 9 may detect the approach of the passing object 3 based only on the reception of the first signal, regardless of the distance from the passing first communication unit 12. In this case, the control unit 9 causes the management second communication unit 8 to suspend transmission of the second signal while receiving the first signal from the passing first communication unit 12.

[0038] Furthermore, when the first method has a parent / child relationship, the passage management system 1 has the management first communication unit 7 as the parent unit and the passage first communication unit 12 as the child unit. With this configuration, the first signal is transmitted from the moving passing object 3, allowing the reader 6 to detect the approach of the passing object 3. Furthermore, by adopting BLE communication as the first method, for example, power consumption on the passing object 3 side can be reduced. Note that power consumption on the passing object 3 may be reduced by adjusting the transmission cycle of the first signal, for example.

[0039] Furthermore, when the control unit 9 detects that the passing object 3 is approaching within a predetermined pause range based on the distance from the passing first communication unit 12 estimated by the first signal received from the passing first communication unit 12, the control unit 9 causes the management second communication unit 8 to pause transmission of the second signal. This prevents the transmission of the second signal from being paused when the passing object 3 is located farther away than the pause range. Therefore, when other passing objects 3 attempt to communicate eligibility information via wireless communication using the second method, the wireless communication using the second method is not interrupted. This allows smoother passage through the passageway 4 even when there are multiple passing objects 3. The distance between the passing first communication unit 12 and the management first communication unit 7 may be measured by the management first communication unit 7. The distance between the passing first communication unit 12 and the management first communication unit 7 may be measured or estimated based on time of flight (TOF) or other information, in addition to estimation based on signal strength.

[0040] Next, an example of the hardware configuration of the traffic control system 1 will be described with reference to FIG. FIG. 3 is a hardware configuration diagram of the main part of the traffic control system 1 according to the first embodiment.

[0041] Each function of the traffic control system 1 can be realized by a processing circuit. The processing circuit includes at least one processor 100a and at least one memory 100b. The processing circuit may include at least one dedicated hardware 200 in addition to or in place of the processor 100a and the memory 100b.

[0042] When the processing circuit includes a processor 100a and a memory 100b, each function of the traffic 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 traffic control system 1 by reading and executing the program stored in the memory 100b. The program may be a program package including multiple subprograms, modules, libraries, or the like. The program may be a product itself, such as a program product, or may be included in the product.

[0043] The processor 100a is also called a CPU (Central Processing Unit), processing device, arithmetic unit, microprocessor, microcomputer, or DSP. The memory 100b is configured by, for example, a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM.

[0044] Where the processing circuitry comprises dedicated hardware 200, the processing circuitry may be implemented, for example, as a single circuit, multiple circuits, a programmed processor, parallel programmed processors, an ASIC, an FPGA, or a combination thereof.

[0045] Each function of the traffic control system 1 can be realized by a processing circuit. Alternatively, each function of the traffic control system 1 can be realized collectively by a processing circuit. Some of the functions of the traffic control system 1 may be realized by dedicated hardware 200, and other parts may be realized by software or firmware. In this way, the processing circuit realizes each function of the traffic control system 1 by dedicated hardware 200, software, firmware, or a combination of these.

[0046] Embodiment 2 In the second embodiment, differences from the example disclosed in the first embodiment will be described in particular detail. For features not described in the second embodiment, any of the features of the example disclosed in the first embodiment may be adopted.

[0047] FIG. 4 is a configuration diagram of a traffic control system 1 according to the second embodiment.

[0048] The passing object 3 moves together with the portable device 11c. For example, the passing object 3, which is a person, carries the portable device 11c and moves together with the portable device 11c. Furthermore, the passing object 3, which is a device, may move together with the portable device 11c by having the portable device 11c attached to its exterior, or may move together with the portable device 11c by having the portable device 11c built in. The portable device 11c is a portable device equipped with a wireless communication function. The portable device 11c may be a smartphone, a smartwatch, or other general-purpose information processing device, or may be an IC tag or other device dedicated to the passage management system 1. In this example, the portable device 11c is a portable general-purpose information processing device such as a smartphone. When the passing object 3 is a person, the portable device 11c may be owned by the passing object 3 or may be loaned to the passing object 3 by the administrator of the facility 2 or the like. The portable device 11c may be a device within the system included in the passage management system 1, or may be a device outside the system that cooperates with the passage management system 1.

[0049] In this example, the portable device 11c has both a first passage communication unit 12 and a second passage communication unit 13. The first passage communication unit 12 has a function of BLE communication as a first method. The second passage communication unit 13 has a function of NFC communication as a second method. The portable device 11c holds the qualification information of the passing object 3. In the passage management system 1, the first passage communication unit 12 functions as a peripheral device of the first method. The second passage communication unit 13 functions as a passive device of the second method in another system of the passage management system 1. In this example, the passing object 3 has the qualification information read by the reading device 6 using the first passage communication unit 12 of the portable device 11c.

[0050] In this way, the first passage communication unit 12 and the second passage communication unit 13 are mounted on the same portable device 11c that moves with the passing object 3. Even when a multifunctional portable device 11c that supports multiple communication methods is used, unintentional activation of the second passage communication unit 13 that communicates using the second method is suppressed when communicating qualification information using the first method. Since the unintentional transmission of information other than qualification information from the second passage communication unit 13 is suppressed, the reading device 6 does not receive unnecessary information. This reduces the information processing load on the reading device 6, so the process of determining whether the passing object 3 is allowed to pass is not hindered. Therefore, the passing object 3 can pass through the passage entrance 4 more smoothly.
