[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, the authentication device may support wireless communication standards other than BLE, such as NFC (Near Field Communication), for the convenience of users. Here, a mobile device that performs BLE communication may also support NFC communication in addition to BLE communication. A user who is going to perform authentication using a mobile device that performs BLE communication may have an IC card (IC: Integrated Circuit) that supports NFC communication in addition to the mobile device. An NFC communication module of the mobile device is activated by a wireless signal from the authentication device. In this case, an NFC communication module of a mobile device held by a user may be unintentionally activated by communication with the authentication device, and may perform communication with the authentication device that is unintentional to the user. In such a case, wireless communication for authentication using the BLE communication of the mobile device is hindered, and authentication of the user is not performed smoothly, which may cause a delay in the passage of the user.

[0005] The present disclosure relates to solving such problems. The present disclosure provides a passage management system, a reading device, a communication method, and a communication program that enable a passing entity such as a user to pass through a passageway that is under management more smoothly even when multiple types of wireless communication are available.

[Diagram 2] 4 is a flowchart showing an example of the operation of the traffic management system according to the first embodiment. [Diagram 3] 1 is a hardware configuration diagram of a main part of a traffic management system according to the first embodiment. [Figure 4] FIG. 11 is a configuration diagram of a traffic management system according to a second 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 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 a part or all of a building. The facility 2 may include one or both of an outdoor part and an indoor part 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 facilities, 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 is, for example, a user of the facility 2 that is a person, or a mobile object that is a device that moves through the facility 2. The mobile object is, 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 device.

[0015] The traffic management system 1 manages the passage of traffic through an entrance 4 for entering and exiting an entrance / exit controlled area. An entrance / exit controlled area is an area that is managed to restrict at least one of entry and exit to only authorized passing bodies 3. An entrance / exit controlled area is, for example, an area inside or outside a building. The entrance 4 is provided at the boundary of the entrance / exit controlled area. The entrance 4 is, for example, the entrance of a building, or an entrance / exit of 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 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 a 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 corresponding to a parent device and a peripheral device corresponding to a child device are set. Before one-to-one BLE communication is established, the peripheral device transmits an advertising signal, which is a wireless signal including information for identifying itself. The advertising signal is an example of a first signal. The advertising signal includes information for identifying 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 an 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 of wireless communication of the second method. The second method is, for example, a short-distance wireless communication method such as NFC communication or UWB communication. In this example, the management second communication unit 8 has a function of NFC communication as the second method.

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

[0021] The control unit 9 is a portion equipped with a function for 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 judges whether the passing object 3 is permitted to pass through the passageway 4 based on the qualification information of the passing object 3 received by the reading device 6 through one or both of the management first communication unit 7 and the management second communication unit 8. The qualification information may be, for example, authentication information for authenticating 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 qualification information of the passing object 3 through 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 qualification information of the passing object 3 through the management second communication unit 8. In this way, the passing object 3 can select to use one or both of the first method and the second method. The judgment of whether the passing object 3 is permitted to pass based on the qualification information may be made by, for example, the control unit 9 of the reading device 6, or may be made 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 or multiple computer devices. A part or all of the central control device 10 may be outside the facility 2. The central control device 10 is connected to a reading device 6 so as to acquire credential information. The central control device 10 is connected to an electronic lock 5 so as to allow an authorized passing body 3 to pass through the passageway 4.

[0023] The passing body 3 moves together with the portable device 11a. For example, the passing body 3, which is a person, moves together with the portable device 11a by carrying the portable device 11a. The passing body 3, which is a device, may move together with the portable device 11a by attaching the portable device 11a to the outside, or may move together with the portable device 11a by incorporating the portable device 11a. In this example, the passing body 3 carrying the portable device 11a also carries another portable device 11b. Here, when the portable device 11a and the portable device 11b are not particularly distinguished from each other, 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 smart watch, or other general-purpose information processing device, or may be an IC tag, an IC card, or other dedicated device for the passage management system 1. When the passing body 3 is a person, the portable device 11 may be owned by the passing body 3, or may be loaned to the passing body 3 by the manager 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 portable device 11a includes a first passage communication unit 12. The first passage communication unit 12 is a part equipped with a function of wireless communication of the first method. In this example, the first passage communication unit 12 has a function of BLE communication as the first method. The portable device 11a is, for example, a portable general-purpose information processing device such as a smartphone. In this example, the portable 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 method.

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

[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 reading device 6 is shown.

[0027] The traveling object 3 carries both the portable device 11a and the portable device 11b and moves with the portable device 11a and the portable device 11b. The first traveling communication unit 12 of the portable device 11a is not paired with any other device. At this time, the first traveling communication unit 12 functioning as a peripheral device transmits an advertising signal. The second management 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. When 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 process 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, RSSI (Received Signal Strength Indicator). 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 preset pause range for the passage entrance 4 based on the estimated distance. The pause range is, for example, a range in which the distance from the reading device 6 adjacent to the passage entrance 4 is shorter than a preset distance. The pause range is, for example, a range in which the distance from the reading device 6 is shorter than about 20 cm to 30 cm. The pause range may be set to other ranges. For example, the control unit 9 determines that the passing object 3 is approaching within the pause range when the distance from the passing object 3 is shorter than a preset 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. When the management second communication unit 8 has already suspended transmission of the polling signal, the control unit 9 continues the suspension of transmission of the polling signal. The control unit 9 suspends transmission of the polling signal for, for example, a preset time. After that, 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, when 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. When 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, when 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] In addition, the reading device 6 may function as a peripheral device and transmit an advertising signal in the first method of 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 or a central device, for example, by settings. The reading device 6 may switch between functioning as a peripheral device or 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 the passage first communication unit 12, the passage second communication unit 13, and the reading device 6. The reading device 6 is provided adjacent to the passage entrance 4 where passage is managed in the facility 2 through which the 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 function of wireless communication of a first method. The passage first communication unit 12 transmits a first signal. The first signal is a wireless signal of a first method including information for identifying the passing object. The passage second communication unit 13 moves together with the passing object 3. The passage second communication unit 13 is equipped with a function of wireless communication of a second method different from the first method. The passage second communication unit 13 is activated by a second signal, which is a wireless signal of the second method. 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 function of wireless communication of the first method. After receiving the first signal from the passage first communication unit 12, the management first communication unit 7 receives qualification information capable of determining whether or not the passage entrance 4 can be passed through by one-to-one communication with the passage first communication unit 12. The management second communication unit 8 is equipped with a function of wireless communication of the second method. 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 suspend transmission of the second signal.

[0037] In this example, the passage management system 1 can use a plurality of wireless communication standards including a first method and a second method for communication of the qualification information for the convenience of the user. Here, the passing body 3 may have a portable device 11a corresponding to the first method for communicating the qualification information about the passage of the passage entrance 4, as well as a portable device 11b corresponding to the second method so that it can be used for other systems. In this case, wireless communication by a plurality of methods can be performed between the portable device 11 and the reading device 6 carried by the passing body 3. Even in such a case, the approach of the passing body 3 halts the transmission of the second signal of the second method, so that the passing second communication unit 13 of the passing body 3 does not start. This prevents the passing second communication unit 13 from starting unintentionally. Unintentional transmission of information other than the qualification information from the passing second communication unit 13 is suppressed, so that the reading device 6 does not receive unnecessary information. This reduces the load of information processing on the reading device 6, so that the process of determining whether the passing body 3 is allowed to pass is not hindered. Therefore, the passing object 3 can pass through the passageway 4 more smoothly. 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. At this time, the control unit 9 causes the management second communication unit 8 to suspend transmission of the second signal while the control unit 9 is receiving the first signal from the passing first communication unit 12.

[0038] Furthermore, in the case where 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, so that the reader 6 can detect the approach of the passing object 3. Furthermore, by adopting, for example, BLE communication as the first method, power consumption on the passing object 3 side can be reduced. Note that power consumption in the passing object 3 may be reduced by adjusting the transmission cycle of the first signal, etc.

[0039] In addition, the control unit 9 causes the management second communication unit 8 to suspend transmission of the second signal when the control unit 9 detects the approach of the passing object 3 within a preset suspension range based on the distance from the passing first communication unit 12 estimated by the first signal received by the management first communication unit 7 from the passing first communication unit 12. As a result, when the passing object 3 is located farther away than the suspension range, the transmission of the second signal is not suspended, so that when other passing objects 3, etc. attempt to communicate qualification information by wireless communication of the second method, the wireless communication of the second method is not hindered. As a result, even when there are multiple passing objects 3, the passage of the passage entrance 4 can be performed more smoothly. 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 TOF (Time Of Flight) 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 a main part of the traffic control system 1 according to the first embodiment.

[0041] Each function of the traffic 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 in place of them.

[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, or libraries. The program may be a product itself, such as a program product, or a program included in the product.

[0043] 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.

[0044] 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.

[0045] Each function of the passage management system 1 can be realized by a processing circuit. Alternatively, each function of the passage management system 1 can be realized collectively by a processing circuit. Some of the functions of the passage management 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 passage management 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 body 3 moves together with the portable device 11c. For example, the passing body 3, which is a person, moves together with the portable device 11c by carrying the portable device 11c. In addition, the passing body 3, which is a device, may move together with the portable device 11c by attaching the portable device 11c to the outside, or may move together with the portable device 11c by incorporating the portable device 11c. The portable device 11c is a portable device equipped with a wireless communication function. The portable device 11c may be a smartphone, a smart watch, 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 body 3 is a person, the portable device 11c may be owned by the passing body 3, or may be loaned to the passing body 3 by the manager of the facility 2 or the like. The portable device 11c may be a device in 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 causes the reading device 6 to read the qualification information by the first passage communication unit 12 of the portable device 11c.

[0050] In this way, the first passing communication unit 12 and the second passing communication unit 13 are mounted on the same portable device 11c that moves with the passing body 3. Even when a multifunctional portable device 11c that supports multiple communication methods is used, unintended activation of the second passing communication unit 13 that communicates in the second method is suppressed when communicating qualification information in the first method. Since unintended transmission of information other than qualification information from the second passing 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, and does not impede the process of determining whether the passing body 3 can pass. Therefore, the passing body 3 can pass through the passageway 4 more smoothly.
