Description

[Technical Field]

[0001] The present invention relates to an unlocking system that controls the unlocking of a door, and to a mobile terminal, an authentication server, an unlock command device, or a door sensor device that are used in the door unlocking system. [Background technology]

[0002] Patent Document 1 describes an electric lock system that can remotely unlock an electric lock that locks a door. Specifically, in this electric lock system, an electric lock device communicates with a mobile terminal that is present within a predetermined operating range centered on the electric lock, and unlocks the door when a passerby who owns the mobile terminal is authenticated as a person authorized to pass through the door. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6811428 Summary of the Invention [Problem to be solved by the invention]

[0004] However, expanding the operating range of the electric lock system is not desirable from a security standpoint, as it takes time for an authenticated passerby who has entered the operating range to reach the door, and it increases the possibility that a third party may pass through the door while it is unlocked, or that the door may be unlocked unintentionally by a mobile terminal located far from the door.

[0005] On the other hand, narrowing the operation range can prevent the above-mentioned situation, but there is a risk that a passerby who enters the operation range may not be able to complete the authentication process before arriving at the door, resulting in the passerby being held up in front of the door.However, simplifying the authentication process and shortening the time required for authentication could result in the security related to the authentication being weakened.

[0006] The present invention has been made to solve the above-mentioned problems, and an intended object of the present invention is to provide an unlocking system that is excellent in security and smooth passage. [Means for solving the problem]

[0007] That is, the present invention has the following configuration.

[0008] [1] a first detection mechanism that detects a passerby within a first set distance from the door, and a second detection mechanism that detects a passerby within a second set distance from the door that is set shorter than the first set distance; a first authentication mechanism that authenticates a passerby detected by the first detection mechanism, and a second authentication mechanism that authenticates a passerby detected by the second detection mechanism; an unlocking mechanism that unlocks the door when a passerby authenticated by the first authentication mechanism is also authenticated by the second authentication mechanism.

[0009] According to the present invention configured in this manner, the door is ultimately unlocked when a passerby enters the second set distance. However, by shortening this second set distance, the door can be unlocked only for the short time it takes for the passerby to reach the door. This prevents security from being weakened by longer unlocking times, and at the same time reduces the risk of unintended unlocking from a position far away from the door. Furthermore, if the second set distance is shortened, for example, the authentication by the second authentication mechanism can be simplified and completed within the short time it takes for the passerby to reach the door, thereby preventing the passerby from having to wait in front of the door for it to be unlocked and ensuring smooth passage. Furthermore, even if the authentication by the second authentication mechanism is simplified, the authentication by the first authentication mechanism is performed in advance, so that the security related to the authentication as a whole can be made sufficient.

[0010] [2] The unlocking system according to [1], wherein the time required for authentication by the first authentication mechanism is longer than the time required for authentication by the second authentication mechanism. With this configuration, the first authentication mechanism can perform sufficient authentication, so that security regarding authentication can be ensured even if the authentication by the second authentication mechanism is simplified.

[0011] [3] The unlocking system described in [1] is characterized in that the first authentication mechanism authenticates passersby based on their attributes and assigns a code to the authenticated passersby, and the second authentication mechanism authenticates them based on the code. In this configuration, if the authentication in the second authentication mechanism is simplified using a simple code, it becomes easy to complete the second authentication before a passerby reaches the door even if the second set distance is shortened, ensuring smooth traffic. At the same time, if complex attribute authentication is performed in the first authentication mechanism, sufficient security can be achieved for the authentication as a whole.

[0012] [4] The first and second detection mechanisms communicate with a portable terminal carried by a passerby to determine whether the passerby is within the first and second set distances. [1] An unlocking system. With this configuration, the detection mechanism can be configured using a commonly used mobile device such as a smartphone, making it easy to introduce the unlocking system of the present invention. Specifically, the location of a passerby can be identified using the GPS of the mobile device, or based on the reception strength of a beacon signal received by the mobile device from a beacon source installed near the door.

[0013] [5] The unlocking system of claim 1, wherein the first detection mechanism and the second detection mechanism are equipped with a distance measuring sensor that measures the distance between the door and a passerby, and detects a passerby based on the distance measured by the distance measuring sensor. With this configuration, it becomes possible to adjust the set distance more precisely.

[0014] [6] The unlocking system of claim 1, wherein the second detection mechanism is equipped with an object detection sensor that detects objects that have entered a predetermined detection area set near the door, and detects passersby based on a detection signal received from the object detection sensor. With this configuration, authentication by the second authentication unit to unlock the door is performed only when the object detection sensor actually detects an object approaching the door, thereby reducing unintended unlocking.

[0015] [7] The unlocking system described in [1], wherein each of the authentication mechanisms authenticates a passerby by communicating with a mobile terminal carried by the passerby. With this configuration, authentication is performed using a commonly used mobile terminal such as a smartphone, making it easy to introduce the unlocking system according to the present invention.

[0016] [8] The unlocking system described in [7], wherein the second authentication mechanism has a second authentication information acquisition unit that communicates locally with the mobile terminal to acquire the authentication information of the passerby, and the second authentication information acquisition unit is provided near the door. If the communication environment between the second authentication mechanism and the mobile device is poor and the communication speed is slow, the authentication may take a long time and may not be completed in time for the passerby to reach the door. However, with the configuration [8], the second authentication is performed via local communication, which makes it easier to create a local communication environment compared to Internet communication, thereby ensuring communication speed and ensuring smooth traffic even if the second set distance is shortened.

[0017] [9] The present invention is used in an unlocking system including a first authentication mechanism for authenticating a person passing through a door, a second authentication mechanism for authenticating the person, and an unlocking mechanism for unlocking the door when the person authenticated by the first authentication mechanism is also authenticated by the second authentication mechanism, a first detection mechanism that detects a passerby within a first set distance from the door, and a second detection mechanism that detects a passerby within a second set distance from the door that is set shorter than the first set distance; a first authentication information transmitting unit that transmits first authentication information to a first authentication mechanism that authenticates a passerby detected by the first detection mechanism, and a second authentication information transmitting unit that transmits second authentication information to a second authentication mechanism that authenticates a passerby detected by the second detection mechanism. Such a portable terminal can achieve the same effects as the unlocking system described above.

[0018]

[10] The present invention is used in an unlocking system including a first detection mechanism that detects a passerby within a first set distance from a door, a second detection mechanism that detects a passerby within a second set distance from the door that is set shorter than the first set distance, a second authentication mechanism that authenticates the passerby detected by the second detection mechanism, and an unlocking mechanism that unlocks the door when the passerby is authenticated by the second authentication mechanism, a first authentication mechanism for authenticating a passerby detected by the first detection mechanism; The first authentication mechanism is an authentication server that authenticates passersby based on their attributes and provides the authenticated passersby with a code required for authentication by the second authentication mechanism. Such an authentication server can also achieve the same effects as the unlocking system described above.

[0019]

[0023] A first embodiment of a human detection device according to the present invention will be described below with reference to the drawings.

[0024] [First embodiment] 1. System Overview The unlocking system according to this embodiment unlocks a door X (here, an automatic door) installed at the entrance of an apartment building or other collective housing, an office, a factory, etc., so that only authorized persons can pass through. This system will be explained using a delivery company that delivers packages to the apartment building as an example of the authorized passerby.

[0025] In this embodiment, the locked state of an automatic door refers to a state in which the door does not automatically open to passersby, and the unlocked state refers to a state in which the door automatically opens. Note that the door may also be a manual door.

[0026] 2. System Configuration 2-1. Overall structure As shown in Figures 1 and 2, this unlocking system 100 is configured using a mobile terminal 1 carried by a passerby, an authentication server 2 that authenticates the passerby, and an unlocking command device 3 that unlocks door X.

[0027] 2-2.Mobile device 1 The mobile terminal 1 includes a CPU, memory, input / output devices such as a touch panel display, a communication interface, etc., and is, for example, a smartphone, tablet, or personal computer. The mobile terminal 1 is configured to be able to communicate with external devices via internet communication using a communication network N and local communication such as BLE.

[0028] As shown in FIG. 3, the mobile terminal 1 functions as a signal receiving unit 11, a position determining unit 12, a first authentication information transmitting unit 13, a first authentication information storing unit 14, a second authentication information transmitting unit 15, a second authentication information storing unit 16, etc., by the CPU and peripheral devices working together in accordance with a predetermined program stored in the memory. The configuration of each of these parts will be described in detail below.

[0029] 2-2-1. Signal receiving unit 11 The signal receiving unit 11 receives a signal from a signal transmitter T whose installation position is known. The signal receiving unit 11 of this embodiment receives a beacon signal using BLE (Bluetooth Low Energy), which is one of the short-range wireless communication technologies.

[0030] The signal transmitter T here is a short-range communication module (here, a BLE module) provided in the unlock command device 3 attached to the door X. The signal transmitter T may be provided separately from the unlock command device 3 on a wall near the door X.

[0031] The beacon signal indicates, for example, the device ID or installation coordinates of the unlock command device 3 or the signal transmitter T, and is transmitted at a predetermined interval. Note that the beacon signal may be transmitted using short-range wireless communication other than BLE (such as Bluetooth or Wi-Fi).

[0032] 2-2-2. Position determination section 12 The position determination unit 12 determines whether the mobile terminal 1 (effectively, a passerby carrying the mobile terminal 1) is within a first set distance from the door X, and whether the mobile terminal 1 is within a second set distance that is set shorter than the first set distance, based on communication between the signal transmitter T and the signal receiving unit 11. Specifically, the position determination unit 12 determines the position of the passerby based on the received signal strength (RSSI: Received Signal Strength Indicator) of the beacon signal received by the signal receiving unit 11.

[0033] The beacon signal used here is BLE, which has low directionality. The RSSI of this beacon signal attenuates as it moves away from door X, where signal transmitter T is installed, in each direction.

[0034] In this embodiment, the determination of whether a passerby is located within each set distance is made based on a comparison between the RSSI reference value defined for each set distance and the RSSI measurement value actually measured by the signal receiving unit 11.

[0035] The RSSI reference value is a reference value that is set based on an RSSI value that is measured in advance at a position that is the set distance away from the door X. The RSSI reference value may be set based on, for example, a correlation between distance and RSSI that is determined in advance. The RSSI reference value here is stored in advance in a predetermined area of ​​the memory of the mobile terminal 1, but may also be included in the beacon signal.

[0036] Here, a first RSSI reference value at the first set distance and a second RSSI reference value at the second set distance are set as the RSSI reference values. As described above, since the second set distance is shorter than the first set distance, the second RSSI reference value is set to a value greater than the first RSSI reference value.

[0037] If the RSSI measurement value is equal to or greater than the first RSSI reference value, the position determination unit 12 determines that the passerby is within a first set distance, and if not, determines that the passerby is farther than the first set distance. If the RSSI measurement value is equal to or greater than the second RSSI reference value, the position determination unit 12 determines that the passerby is within a second set distance, and if not, determines that the passerby is farther than the second set distance.

[0038] In addition, a considerable difference is left between each set distance or each RSSI reference value so that people within each set distance can be detected separately even if they are affected by individual differences in the mobile terminal 1 or reflected waves of the beacon signal, for example.

[0039] The signal receiving unit 11 and the position determining unit 12 of this embodiment described above correspond to the first detection mechanism D1 and the second detection mechanism D2 in the claims.

[0040] 2-2-3. First authentication information transmission unit 13 The first authentication information transmission unit 13 transmits first authentication information to the authentication server 2 via internet communication when the position determination unit 12 determines that a passerby is located within a first set distance from the door X, that is, when the passerby is detected by the first detection mechanism D1. The first authentication information transmitted here is pre-stored in a first authentication information storage unit 14 set in a predetermined area of ​​the memory of the mobile terminal 1.

[0041] The first authentication information is information for identifying the identity of the passerby. In this embodiment, the first authentication information includes, for example, a company number that identifies the company to which the passerby (delivery company) belongs, as attribute information.

[0042] Attribute information is information for directly or indirectly identifying the attributes of passersby, such as affiliation, job responsibilities, position, employee number, membership status, etc. Attribute information may not only be such public information, but also personal information such as name, address, and personal identification number.

[0043] 2-2-4. Second authentication information transmission unit 15 The second authentication information transmitting unit 15 transmits second authentication information to the unlock command device 3 via local communication when the position determining unit 12 determines that a passerby is within a second set distance from the door X, that is, when the passerby is detected by the second detection mechanism D2. The second authentication information transmitted here is stored in the second authentication information storage unit 16 set in a predetermined area of ​​the memory of the mobile terminal 1.

[0044] The second authentication information, like the first authentication information, is information for identifying the identity of a passerby. The second authentication information in this embodiment is an assignment code assigned by the authentication server 2, and is information for identifying whether or not the passerby has been successfully authenticated using the first authentication information in the authentication server 2. The second authentication information may include attribute information stored in the second authentication information storage unit 16.

[0045] 2-3.Authentication Server 2 The authentication server 2 is a computer equipped with a CPU, memory, a communication interface, etc. The authentication server 2 may be a virtualized computer provided in, for example, a cloud. The authentication server 2 is configured to be able to communicate with external devices via internet communication using the communication network N.

[0046] This authentication server 2 performs functions such as a first authentication information acquisition unit 21, a first registration information acquisition unit 22, a first registration information storage unit 23, a first judgment unit 24, a code assignment unit 25, etc., by the CPU and peripheral devices working together in accordance with a predetermined program stored in the memory. The configuration of each of these parts will be described in detail below.

[0047] 2-3-1. First authentication information acquisition unit 21 The first authentication information acquisition unit 21 acquires first authentication information from a passerby detected by the first detection mechanism D1, and here receives the first authentication information from the first authentication information transmission unit 13.

[0048] 2-3-2. First registration information acquisition unit 22 The first registration information acquisition unit 22 acquires first registration information indicating passersby who are permitted to pass through the door X.

[0049] The first registration information is registered in advance by, for example, an apartment management company or a security company, and includes attribute information of passersby who are permitted to pass through (here, the company number of the delivery company). It may also include, for example, personal numbers of apartment residents, or company numbers or employee numbers of other businesses that come in and out of the building, but the first registration information must be at least comparable to part of the first authentication information.

[0050] 2-3-3. First registration information storage unit 23 The first registration information storage unit 23 is set in a predetermined area of ​​the memory of the authentication server 2, and stores the first registration information in advance.

[0051] 2-3-4.First judgment section 24 The first judgment unit 24 compares the first authentication information acquired by the first authentication information acquisition unit 21 from the passerby detected by the first detection mechanism D1 with the first registration information acquired by the first registration information acquisition unit 22, and determines whether the passerby detected by the first detection mechanism D1 is a person permitted to pass through door X.

[0052] Here, the first judgment unit 24 compares the attribute information of the passerby contained in the first authentication information with the attribute information contained in the first registration information, and if there is a match, it judges that the passerby detected by the first detection mechanism D1 is a person permitted to pass through door X, and if there is no match, it judges that the passerby is not a person permitted to pass.

[0053] 2-3-5. Code assignment section 25 The code assigning unit 25 assigns an assignment code to a passerby who is determined by the first judging unit 24 to be a person permitted to pass through the door X. Specifically, the code assigning unit 25 transmits an assignment code (referred to as a code in claims) stored in advance in a predetermined area of ​​the memory of the authentication server 2 to the mobile terminal 1, for example, via Internet communication. The assigned assignment code serves as information for identifying the passerby to whom the assignment code was assigned as a person authenticated by the authentication server 2.

[0054] The grant code is a code required to unlock the door X, and in this case is a unique password predetermined for each unlock command device 3. The grant code may be a one-time password generated by the code granting unit 25, or the like.

[0055] The first authentication information acquisition unit 21, the first registration information acquisition unit 22, the first registration information storage unit 23, the first determination unit 24, and the code assignment unit 25 of the present embodiment described above correspond to the first authentication mechanism A1 in the claims. Hereinafter, authentication by this first authentication mechanism A1 will be referred to as the first authentication.

[0056] 2-4. Unlock command device 3 As shown in Figures 1 to 3, the unlock command device 3 is attached to, for example, the door X, and includes a housing (not shown) and an information processing device (not shown) housed in the housing. The information processing device is a computer equipped with a CPU, memory, a communication interface, etc. The information processing device is configured to be able to communicate with external devices via local communication such as BLE.

[0057] Furthermore, the unlocking designation device of this embodiment includes the signal transmitter T described above in the housing.

[0058] The information processing device performs functions such as a second authentication information acquisition unit 31, a second registration information acquisition unit 32, a second registration information storage unit 33, a second judgment unit 34, and an unlocking signal transmission unit 35 by the CPU and peripheral devices working together in accordance with a predetermined program stored in the memory. The configuration of each of these parts will be described in detail below.

[0059] 2-4-1. Second authentication information acquisition unit 31 The second authentication information acquisition unit 31 acquires second authentication information from a passerby detected by the second detection mechanism D2, and receives the second authentication information from the second authentication information transmission unit 15 here.

[0060] 2-4-2. Second registration information acquisition unit 32 The second registration information acquisition unit 32 acquires second registration information indicating passersby who are permitted to pass through the door X. When the second authentication information acquisition unit 31 acquires second authentication information, the second registration information acquisition unit 32 acquires second registration information from the second registration information storage unit 33 that can be compared with the second authentication information.

[0061] The second registration information here is a unique password (hereinafter referred to as a setting code) that is predetermined for each unlock command device 3. The second registration information may be any information that can be compared with at least a part of the first authentication information.

[0062] 2-4-3. Second registration information storage unit 33 The second registration information storage unit 33 is set in a predetermined area of ​​the memory of the information processing device, and stores the second registration information in advance.

[0063] 2-4-4.Second Judgment Department 34 The second judgment unit 34 compares the second authentication information acquired by the second authentication information acquisition unit 31 from the passerby detected by the second detection mechanism D2 with the second registration information acquired by the second registration information acquisition unit 32, and determines whether the passerby detected by the second detection mechanism D2 is a person permitted to pass through door X.

[0064] Here, the second judgment unit 34 compares the assigned code held by the passerby with the set code held by the unlocking command device 3, and if they match, it judges that the passerby detected by the second detection mechanism D2 is a person permitted to pass through door X, and if they do not match, it judges that the person is not permitted to pass.

[0065] The second authentication information acquisition unit 31, the second registration information acquisition unit 32, the second registration information storage unit 33, and the second determination unit 34 of the present embodiment described above correspond to the second authentication mechanism A2 in the claims. Hereinafter, authentication by this second authentication mechanism A2 will be referred to as second authentication.

[0066] In this embodiment, the authentication contents are made different between the first authentication (attribute authentication) and the second authentication (code authentication) so that the time required for the second authentication is shorter than the time required for the first authentication.

[0067] 2-4-5. Unlock signal transmission unit 35 The unlocking signal transmitting unit 35 transmits an opening / closing command signal to the opening / closing drive device of door X to open door X when the first judgment unit 24 judges that the passerby detected by the first detection mechanism D1 is a person permitted to pass through door X, and when the second judgment unit 34 judges that the passerby detected by the second detection mechanism D2 is a person permitted to pass through door X.

[0068] Here, the second authentication mechanism A2 of this embodiment performs authentication using the grant code granted when authentication by the first authentication mechanism A1 is successful, so if this authentication is successful, it means that authentication has been successful by both the first authentication mechanism A1 and the second authentication mechanism A2. Therefore, the unlock signal transmission unit 35 of this embodiment determines that authentication by the first authentication mechanism A1 has also been successful when authentication by the second authentication mechanism A2 is successful.

[0069] As described above, the unlocking signal transmitting unit 35 of this embodiment corresponds to the unlocking mechanism L in the claims.

[0070] 3.Operation

[0071] Hereinafter, with reference to FIGS. 4 and 5, the operations of the first authentication and the second authentication when the passerby is a delivery service provider will be described.

[0072] 3-1. First authentication (attribute authentication) In the unlocking system of this embodiment, as shown in Figures 1 and 2, a beacon signal is constantly transmitted from a signal transmitter T near the door toward the periphery of the door X. When a delivery company approaches the door X, the mobile terminal 1 of the delivery company receives the beacon signal (step S11).

[0073] As the delivery company approaches door X, the RSSI measurement value of the beacon signal gradually increases. When the RSSI measurement value becomes equal to or greater than the first RSSI reference value, the location determination unit 12 determines that the delivery company is within a first set distance from door X (step S12), and the first authentication information transmission unit 13 attempts to communicate with the authentication server 2 via the Internet.

[0074] When internet communication is established (step S13), the first authentication information transmitting unit 13 links the first authentication information of the delivery company with information for identifying the door X through which the delivery company is about to pass, and transmits the linked information to the first authentication information acquiring unit 21 (step S14). Here, the device ID of the unlocking command device 3 indicated by the beacon signal is linked to the first authentication information as information for identifying the door X.

[0075] When the first authentication information acquisition unit 21 receives the first authentication information, the first registration information acquisition unit 22 checks the device ID linked to the first authentication information and identifies the door X through which the passerby is about to pass. Then, the first registration information indicating permission to pass through the door X is acquired from the first registration information storage unit 23 (step S15).

[0076] The first judgment unit 24 searches the first registration information acquired by the first registration information acquisition unit 22 and determines whether there is any first registration information that includes the company number indicated in the first authentication information, i.e., whether the delivery company is authorized to pass through (step S16).

[0077] When the first determination unit 24 determines that the delivery agent is permitted to pass through, the code assignment unit 25 transmits an assignment code to the mobile terminal 1. The assignment code received by the mobile terminal 1 is stored in the second authentication information storage unit 16 as second authentication information (step S17). This completes the first authentication.

[0078] 3-2. Second authentication (code authentication) If the delivery company approaches door X further and the RSSI measurement value of the beacon signal received by the mobile terminal 1 becomes equal to or greater than the second RSSI reference value, the location determination unit 12 determines that the delivery company is within a second set distance from door X (steps S21 and S22), and the second authentication information transmission unit 15 attempts local communication with the unlocking command device 3.

[0079] When the local communication is established (step S23), the second authentication information transmitting unit 15 transmits the grant code to the second authentication information acquiring unit 31 (step S24).

[0080] When the second authentication information acquisition unit 31 receives the grant code, the second registration information acquisition unit 32 acquires the setting code, and the second judgment unit 34 determines whether the grant code matches the setting code, i.e., whether the delivery company is authorized to pass through (step S25).

[0081] If the second determination unit 34 determines that the delivery company is authorized to pass through, the unlocking signal transmission unit 35 transmits an opening / closing command signal to the opening / closing drive device to open the door X (step S26). This completes the second authentication, and the delivery company can pass through the door X to perform delivery.

[0082] 4.Effects With the unlocking system 100 configured in this way, the door X is finally unlocked after the passerby enters the second set distance, which is set to be shorter, so that the door X can be unlocked only for the short time it takes for the passerby to reach the door X, thereby preventing security from being weakened due to a longer unlocking time for the door X. At the same time, the risk of unintended unlocking from a position far from the door X can be reduced.

[0083] Since the second authentication mechanism A2 performs simple code authentication, this second authentication can be completed in the short time it takes for a passerby to reach door X, preventing a situation in which a passerby has to wait in front of the door for it to be unlocked and ensuring smooth traffic flow.

[0084] Since the authentication by the second authentication mechanism A2 is performed via local communication between the unlock command device 3 and the mobile terminal 1, it is unlikely that a situation will arise in which authentication takes a long time due to the network environment.

[0085] Furthermore, even if simple code authentication is performed by the second authentication mechanism A2, attribute authentication by the first authentication mechanism A1 is performed in advance, so the security related to authentication as a whole is sufficient. Also, since the time the door remains unlocked does not increase even if the first set distance is increased, it is easy to operate the system by lengthening the first set distance and employing complex attribute authentication by the first authentication mechanism A1.

[0086] The system is easy to implement because it uses the mobile terminal 1 of the passerby to unlock the vehicle. By using the mobile terminal 1, passersby can be authenticated while they are moving once they have entered a set distance, ensuring smooth traffic flow.

[0087] Because RSSI is used, the distance measurement accuracy indoors is better than when the distance between door X and a passerby is determined using, for example, the GPS of the mobile terminal 1.

[0088] Since authentication is performed using the authentication information stored in advance in the mobile terminal 1, it is convenient to support hands-free authentication.

[0089] [Second embodiment] The portable terminal of this embodiment further functions as a distance measurement unit that measures the distance between the signal transmitter and the portable terminal. Since the signal transmitter is provided near the door and the portable terminal is carried by a passerby, the distance measurement unit essentially measures the distance between the door and the passerby (hereinafter also referred to as the measured distance).

[0090] The distance measurement unit measures the measured distance based on the RSSI measurement value. The distance measurement unit calculates the measured distance from the RSSI measurement value based on, for example, a correlation between RSSI and distance calculated in advance. The position determination unit then compares the measured distance with each set distance and determines whether a passerby is within each set distance.

[0091] In this embodiment, the signal receiving unit, the distance measuring unit, and the position determining unit correspond to the first detection mechanism D1 and the second detection mechanism D2 in the claims.

[0092] An unlocking system configured in this way allows for more precise adjustment of the set distance. In addition, by estimating the speed of a passerby based on the measured distance, the door control unit can determine whether or not the passerby intends to pass and then decide whether to unlock the door.

[0093] Here, the signal receiving unit and distance measuring unit function as a distance measuring sensor that measures the distance between the door and the passerby, but the distance between the door and the passerby may also be measured using a distance measuring sensor that uses, for example, LiDAR, RADAR, ultrasound, etc. installed around the door.

[0094] [Third embodiment] As shown in FIG. 6, the mobile terminal 1 of this embodiment further functions as a position specifying unit that specifies the position of a passerby, in addition to the distance measuring unit described above.

[0095] The signal receiving unit 11 of this embodiment receives beacon signals from two signal transmitters T1 and T2 installed in different locations. The two signal transmitters T1 and T2 are attached to a wall on which a door X is installed, with the door X sandwiched between them. The beacon signal also includes information about at least the installation coordinates of the signal transmitters.

[0096] The distance measurement unit measures the distance between each of the signal transmitters T1, T2 and passersby based on the beacon signals received from each of the signal transmitters T1, T2.

[0097] The position determination unit confirms the installation coordinates of the signal transmitters T1 and T2 indicated by the beacon signal received by the signal receiving unit 11, and determines the position (planar coordinates) of the passerby based on these two installation coordinates and the measured distance measured by the distance measuring unit.

[0098] The position determination unit 12 of this embodiment determines whether or not the passerby is in a first authentication area set within a first set distance or a second authentication area set within a second set distance based on the identified position of the passerby. Note that the position determination unit may simply determine whether or not the passerby is within the first set distance or within the second set distance from the door X.

[0099] In this embodiment, the signal receiving unit, the distance measuring unit, the position specifying unit, and the position determining unit correspond to the first detection mechanism D1 and the second detection mechanism D2 in the claims.

[0100] With an unlocking system configured in this way, the range in which each authentication is performed can be limited to the range of each authentication area, further reducing the risk of unintended unlocking of door X.

[0101] Furthermore, by identifying the movement route based on the change in the position of a passerby over time, it becomes possible for the door control unit to determine whether or not the passerby intends to pass and then decide whether to unlock the door. Furthermore, by recording the detected position and movement route of a passerby, this can be referenced when resetting the set distance or authentication area, further improving traffic smoothness and security.

[0102] The position specifying unit may specify the position of a passerby based on beacon signals from three or more signal transmitters received by the signal receiving unit 11. In this case, the position of a passerby can be specified in more detail.

[0103] Here, the location identification unit identifies the location of a passerby based on the distance between the signal transmitter, whose installation coordinates are known, and the mobile device, but the method of location identification is not limited to this. For example, multiple signal transmitters may be installed around the door, and the RSSI values ​​at each position around the door may be pre-learned, and the location of the mobile device may be directly identified based on the learning results. Alternatively, the location of a passerby may be identified using other methods, such as using the mobile device's GPS.

[0104] [Fourth embodiment] In this embodiment, as shown in FIGS. 7 and 8, the unlock command device 3 is a door sensor device further comprising an object detection sensor S.

[0105] The object detection sensor S is provided inside the housing of the door sensor device, and detects an object present in a detection area set within a second set distance from the door X and outputs a detection signal indicating the presence of the object. Here, the detection signal is transmitted to the position determination unit 12 via local communication.

[0106] The object detection sensor S here is a passive infrared sensor, but various types can be used, such as an active infrared sensor, a radar sensor using microwaves or millimeter waves, or a camera sensor using an imaging element.

[0107] In this embodiment, the position determination unit 12 determines that the passerby is within a first set distance if the RSSI measurement value is equal to or greater than the first RSSI reference value, and otherwise determines that the passerby is farther than the first set distance. Furthermore, when the position determination unit 12 receives the detection signal, it determines that the passerby is within a second set distance, and otherwise determines that the passerby is farther than the second set distance.

[0108] In this embodiment, the object detection sensor S and the position determination unit correspond to the second detection mechanism D2 in the claims.

[0109] In this way, an unlocking system using the object detection sensor S can detect passersby more accurately than a system using RSSI, which is more susceptible to external disturbances. This allows the second set distance to be set more precisely, thereby reducing the chance of unintentional unlocking of door X and more reliably preventing passersby from waiting in front of the door for it to be unlocked.

[0110] Like the second detection mechanism D2, the first detection mechanism D1 may be configured using the object detection sensor or another distance measuring sensor described above. Furthermore, the functions of the position determination unit 12 in this embodiment may be provided separately in the mobile terminal and the door sensor device. Specifically, a first position determination unit that determines whether a passerby is within a first set distance may be provided in the mobile terminal, and a second position determination unit that determines whether a passerby is within a second set distance may be provided in the door sensor device.

[0111] [Fifth embodiment] The unlock command device 3 of this embodiment is also a door sensor device equipped with an object detection sensor S, as in the fourth embodiment, as shown in FIG.

[0112] The object detection sensor S detects an object present in a detection area set near the doorway area and outputs a detection signal indicating this, and is physically similar to that described in the fourth embodiment. The detection area here is set within a second set distance, but is not limited to this.

[0113] The unlock signal transmitting unit 35 here outputs an opening / closing command signal for the door X based not only on the judgment results of the first judgment unit 24 and the second judgment unit 34 but also on the detection signal output from the object detection sensor S. That is, this door control unit transmits an opening / closing command signal to the opening / closing drive device of the door X to open the door X when the first judgment unit 24 and the second judgment unit 34 have judged that the detected passerby is a person permitted to pass and when a person is detected by the object detection sensor.

[0114] In this embodiment, the object detection sensor S and the unlocking signal transmitting unit correspond to the unlocking mechanism L in the claims.

[0115] With an unlocking system configured in this manner, door X is unlocked only when the body of a passerby is actually detected in front of the door, thereby reducing the risk of unintended unlocking of door X. In addition, in this embodiment, the detection area is set within the second set distance, so the unlocking time of door X can be further shortened, further strengthening security.

[0116] [Sixth embodiment] The signal receiving unit of this embodiment receives a first beacon signal and a second beacon signal as beacon signals, and the position determining unit compares the RSSI measurement value of the first beacon signal with a first RSSI reference value to determine whether a passerby is located within a first set distance, and compares the RSSI measurement value of the second beacon signal with a second RSSI reference value to determine whether a passerby is located within a second set distance.

[0117] The second beacon signal here is not transmitted constantly, but is transmitted, for example, when a passerby is detected by the first detection mechanism or when an object is detected by an object detection sensor provided in the unlocking command device.

[0118] This means that the second beacon signal required for final door unlocking is not constantly being transmitted, reducing unintentional unlocking and improving security.

[0119] The second beacon signal may be constantly transmitted, in which case the signal receiving unit may receive the first beacon signal and the second beacon signal from different signal transmitters. For example, if the first beacon signal is received from a signal transmitter installed at a position far from the door and the second beacon signal is received from a signal transmitter installed at a position close to the door, it is possible to make it difficult for the second beacon signal to reach positions far from the door, thereby expanding the range in which authentication can be started and more reliably limiting the positions where unlocking can be performed to the vicinity of the door.

[0120] Furthermore, the output amount of the second beacon signal may be set to be smaller than the output amount of the first beacon signal.

[0121] [Seventh embodiment] The first set distance and the second set distance in this embodiment are set as distances (so-called journey distances) on the route that a passerby takes on his way to door X, as shown in FIG.

[0122] When the first detection mechanism D1 determines the distance between the door X and a passerby based on the RSSI, the first RSSI reference value may be set based on a value measured in advance at a position on the route that is a first set distance from the door X. The same applies to the second RSSI reference value.

[0123] In this way, even if the path to the door where the system is installed is not a straight line, the first authentication can be performed at a position where it takes a long time to reach the door, and the second authentication can be performed at a position where it takes a short time to reach the door.

[0124] By using the position identification unit described in the third embodiment or the object detection sensor described in the fourth embodiment, each determination unit can accurately determine the position of pedestrians traveling along complex routes.

[0125] [Other embodiments] Each detection mechanism may detect a passerby within a predetermined set distance. For example, a first detection mechanism may detect a passerby within a range between a first set distance and a second set distance, i.e., within the first set distance from the door but farther than the second set distance. This would prevent the door from being unlocked by a passerby, for example, coming through the door from the unlocked side and staying within the second set distance.

[0126] Each detection mechanism may determine the distance between the door and a passerby based on the RSSI of a signal other than the beacon signal.

[0127] The first and second detection mechanisms may determine the distance between the door and the passerby using the GPS function of the mobile terminal, or may determine the approach from a position at the first set distance to a position at the second set distance using an acceleration sensor or gyro sensor built into the mobile terminal.

[0128] The unlocking system may include a third detection mechanism that detects a passerby within a third set distance and a third authentication mechanism that authenticates a passerby detected by the third detection mechanism, or may include further detection mechanisms and authentication mechanisms.

[0129] The first authentication acquisition unit or the second authentication acquisition unit may acquire and authenticate a password or biometric information input from an input device (such as a touch panel or camera) of the mobile terminal. Alternatively, authentication may be performed by combining this with information previously stored in the mobile terminal.

[0130] The code assigning unit may change the type of assignment code to be assigned to a passerby depending on the content of the attribute information included in the first authentication information acquired by the first authentication information acquiring unit. The unlocking signal transmitting unit may change the control mode for the door (door opening time, opening / closing speed, degree of opening, etc.) depending on the type of assignment code. For example, the unlocking signal transmitting unit may lengthen the door opening time for a passerby with an attribute that is expected to move slowly, such as a moving company.

[0131] The second authentication information acquisition unit 31 may acquire the second authentication information from an input device or the like installed in front of the door.

[0132] The unlocking mechanism may have an opening / closing drive device that actually physically opens the door.

[0133] Although the unlocking system in each of the above-described embodiments is configured with a door control device, a mobile terminal, and an authentication server, the physical configuration of the human detection device according to the present invention is not limited to this.Furthermore, the physical locations of the functional units are not limited to the locations shown in each of the embodiments.

[0134] For example, the function of the first determination unit or the second determination unit may be performed by a mobile terminal. Furthermore, the function of the second determination unit may be performed by an authentication server. In this case, if the unlocking command device is connected to a network via a wired connection, the unlocking command device can obtain the result of the second authentication without being affected by the wireless network communication environment. Furthermore, it is also possible for the unlocking command device to transmit the grant code received from the mobile terminal via local communication to the authentication server.

[0135] In addition, when each detection mechanism utilizes an object detection sensor, the object detection sensor may be provided in an object detection device separate from the unlock command device. [Explanation of symbols]
