<First embodiment>
FIG. 1 is a block diagram showing the configuration of the electronic lock system according to the first embodiment of the present invention. As illustrated, the electronic lock system includes a terminal device 1, a key opening / closing device 2, and a sensor 3.

  The terminal device 1 can communicate with the key opening / closing device 2 by approaching within a predetermined distance. The terminal device 1 transmits authority information (for example, terminal identification information that can uniquely identify the terminal device 1) indicating that it has the authority for unlocking to the key opening / closing device 2. The sensor 3 can be connected to the key opening / closing device 2 via the communication network 6. The communication network 6 may be either wired communication or wireless communication. When the sensor 3 detects an environmental change around the sensor due to the user's action, a signal is transmitted to the key opening / closing device 2. In the key opening / closing device 2, unlocking is performed when a signal is received from the sensor 3 until a predetermined time elapses after receiving the authority information from the terminal device 1.

  Examples of the sensor 3 include an electrostatic sensor and an infrared sensor. Hereinafter, in the present embodiment, a case where an electrostatic sensor is used as the sensor 3 will be described as an example. Here, as the environmental change around the sensor, there is a case where a change in electrostatic quantity is detected by the electrostatic sensor when the user touches the door knob.

  FIG. 2 is a block diagram showing the configuration of the terminal device according to the first embodiment of the present invention. The terminal device 1 is a terminal device possessed by a user who wants to open a key, and examples thereof include a mobile phone and a smartphone. The terminal device 1 includes a control unit 11, a RAM 12, a display unit 13, a storage 15, an input unit 16, and a communication interface 17, which are connected by an internal bus.

  The control unit 11 includes a CPU and a ROM. The control unit 11 executes a program stored in the storage 15 and controls the terminal device 1. Moreover, the control part 11 is provided with the internal timer which time-measures. The RAM 12 is a work area for the control unit 11. The storage 15 is a storage area for storing programs and data. The control unit 11 reads a program and data necessary for unlocking by the key opening / closing device 2 from the RAM 12 and performs processing.

  The display device 13 has a display screen 14. The control unit 11 outputs a drawing command and outputs a video signal for displaying an image on the display screen 14. The input unit 16 includes, for example, a button or a touch panel display screen. Information input from the input unit 16 by the user is stored in the RAM 12, and the control unit 11 executes various arithmetic processes based on the input information.

  The terminal device 1 can be connected to the communication network 6 through the communication antenna 17 b and transmits and receives information to and from the server device 1. For example, the terminal device 1 receives a signal from the key opening / closing device 2 via Bluetooth (registered trademark) 17a, and transmits terminal identification information for identifying the terminal device 1 to the key opening / closing device 2 as authority information. By adopting Bluetooth (registered trademark) as a communication method between the terminal device 1 and the key opening / closing device 2, the power consumption in the key opening / closing device 2 is reduced compared to the case where other communication methods are adopted, and the battery is installed. Can last longer. Therefore, the frequency of maintenance such as battery replacement can be reduced. The position of the terminal device 1 can also be specified by the GPS 17c.

  FIG. 3 is a block diagram showing the configuration of the key opening / closing device according to the first embodiment of the present invention. The key opening / closing device 2 may be installed on the door as the door key mechanism itself, or may be installed externally on a normal door with a key. Since the key opening / closing device 2 is not attached as a key for a new door, but can be installed on a door with an existing key attached, the electronic lock system of the present invention can be introduced at a lower cost. it can.

  The key opening / closing device 2 includes a control device 21, a communication interface 22, a storage area 23, a battery 24, and a key opening / closing unit 25, and each is connected by an internal bus. The control device 21 controls opening / closing of the key by the key opening / closing unit 25, and outputs an unlocking execution request to the key opening / closing unit 25 by receiving an unlocking signal from the sensor 3.

  The communication interface 22 periodically transmits a signal to be received by the terminal device 1 and receives authority information from the terminal device 1. Communication between the terminal device 1 and the key opening / closing device 2 is performed by, for example, Bluetooth (registered trademark) 22a. The communication interface 22 transmits an activation signal for activating the sensor 3 and receives an unlock signal from the sensor 3. Communication between the sensor 3 and the key opening / closing device 2 is performed by, for example, the communication antenna 22b, the wireless LAN 22c, and the like. The battery 24 supplies power to the control device 21, the communication interface 22, the storage area 23, and the key opening / closing unit 25. The key opening / closing unit 25 has a function of opening / closing a key.

  Next, the unlocking process in the first electronic lock system of the present invention will be described. FIG. 4 is a flowchart of the unlocking process according to the first embodiment of the present invention. A user who intends to unlock the key possesses a terminal device that has been registered in advance as being the terminal device of the user, and approaches a distance that allows communication with the key opening / closing device 2 and Bluetooth (registered trademark). The unlocking process is started. Here, the communication between the terminal device 1 and the key opening / closing device 2 is performed by Bluetooth (registered trademark). However, the communication method is not limited to this, and can be selected as appropriate.

  First, the key opening / closing device 2 periodically transmits a signal once every few seconds. The key opening / closing device 2 transmits a signal (step S1), and the terminal device 1 receives the signal (step S2). Since the distance of the signal is limited, the transmitted signal is received by the terminal device 1 when the terminal device 1 approaches within a predetermined distance from the key opening / closing device 2. Terminal identification information that can uniquely identify each terminal apparatus is transmitted to the key opening / closing apparatus 2 (step S3).

  When the terminal identification information is received by the key opening / closing device 2 (step S4), it is determined whether the received terminal identification information has the authority to unlock the key (that is, in the key opening / closing device 2 in advance). A determination is made as to whether or not it matches the registered terminal identification information) (step S5). If it is determined that the terminal identification information received by the key opening / closing device 2 does not have the authority to unlock (NO in step S5), the process ends without being unlocked. On the other hand, when it is determined that the terminal identification information received by the key opening / closing device 2 has the authority to unlock (YES in step S5), unlock permission information is set (step S6). ), Timing is started (step S7).

  In step S5, the presence / absence of the authority for unlocking is determined based on the terminal identification information. For example, the server apparatus determines whether the authority is present based on the information for identifying the key opening / closing device 2 and the terminal identification information. When it is determined and it is determined that the user has authority, the unlocking information can be transmitted to the key opening / closing device 2 to be unlocked.

  Next, the key opening / closing device 2 transmits an activation signal for activating the sensor 3 to the sensor 3 (step S8). When the activation signal is received by the sensor 3 (step S9), the sensor 3 is activated (step S10). In step S5, it is possible to lengthen the battery of the sensor by starting the sensor after it is determined that the terminal device 1 has authority. Further, since the sensor is normally in a sleep state, it also serves as a countermeasure against hacking.

  When the environmental change around the sensor is detected by the user's action, that is, when the user touches the door knob, and the change in the electrostatic amount is detected by the sensor 3 connected to the door knob (step S11). An unlock signal is transmitted to the key opening / closing device 2 (step S12). Note that the sensor 3 returns to a standby state when a predetermined time has elapsed since activation.

  When the unlocking signal is received by the key opening / closing device 2 (step S13), the elapsed time from the start of timing in step S7 until the unlocking signal is received is within a predetermined time. It is determined whether or not unlocking permission information is set (step S14).

  If the elapsed time from the start of timing in step S7 until the unlock signal is received is within a predetermined time and unlock permission information is set (in step S14) YES), the key is opened by the key opening / closing unit 25 (step S15). The unlocking permission information set in step S6 is canceled (step S16), and the time measurement started in step S7 ends (step S17), whereby the unlocking process ends.

  If the elapsed time from the start of timing in step S7 until the unlocking signal is received is outside a predetermined time, or when the unlocking permission information is released (step S14) In step S16 and S17, the unlocking permission information is canceled and the timing is terminated.

  In step S14, it is determined that the elapsed time from the start of timing until the unlock signal is received is determined to be within a predetermined time. If it takes too much time for the unlocking signal to be transmitted by the sensor 3 after the person approaches the key opening / closing device 2 while holding the terminal device 1, it is not unlocked, which is preferable from the viewpoint of security. Moreover, security can be further improved by unlocking on the condition that unlocking permission information is set.

  The key opening / closing device 2 can be installed on the indoor side of an existing door with a key. A thumb turn that opens and closes the lock is installed inside the door. By turning the thumb turn knob, the door can be locked and unlocked. A fixing tool that rotates in conjunction with a motor provided in the key opening / closing portion 25 is fixed to the thumb turn knob. When the unlocking signal is received from the sensor 3, the elapsed time from the start of timing in step S7 until the key opening / closing device 2 receives the unlocking signal in step S13 is within a predetermined time. In this case, the motor is driven and the rotation shaft of the motor rotates at a predetermined angle. In conjunction with the rotation of the rotation shaft, the fixing tool fixed to the thumb turn knob rotates, and as a result, the thumb turn knob rotates to unlock.

  As the sensor 3, external hardware with an electrostatic sensor can be installed on the thumb turn of an existing door. The thumbturn and the outdoor doorknob are connected by a conductive material such as metal, and when the user touches the outer doorknob, the electrostatic amount detected by the electrostatic sensor changes. That is, a change in electrostatic quantity is detected in step S11.

  As the sensor 3, the thumb-turn cylinder of the existing door can be replaced with hardware with an electrostatic sensor. The thumbturn cylinder and the outdoor doorknob are connected by a conductive material such as metal, and when the user touches the outer doorknob, the electrostatic quantity detected by the electrostatic sensor changes. That is, a change in electrostatic quantity is detected in step S11.

  Even after the unlocking is performed, the signal is transmitted from the key opening / closing device 2, and when the terminal device 1 receives the signal, the signal is transmitted from the terminal device 1 to the key opening / closing device 2. However, when the user enters the room and the strength of the signal received by the terminal device 1 becomes weaker than the predetermined strength due to the distance between the key opening / closing device 2 and the terminal device 1, the terminal The device 1 does not send a signal back to the key opening / closing device 2. When the key opening / closing device 2 does not detect a signal from the terminal device 1, the key opening / closing unit 25 locks the signal.

  By the way, by using a dedicated application (hereinafter also referred to as a dedicated application) in the terminal device 1, after receiving a signal from the key opening / closing device 2 in step S2, the terminal identification information is sent to the server device 1 in step S3. It is possible to automatically execute processing up to transmission. The dedicated application is automatically activated upon receiving a signal from the key opening / closing device 2. Therefore, unlocking can be performed without operating the terminal device 1.

  Next, a dedicated application automatic activation process in the terminal device 1 will be described. FIG. 5 is a diagram showing a flowchart of the dedicated application automatic start processing according to the embodiment of the present invention. First, a signal is transmitted from the key opening / closing device 2 to the terminal device 1 (step S1), and the signal is received by the terminal device 1 (step S2). The transmission of the signal in step S1 is performed by periodically transmitting the signal at a frequency of, for example, once every few seconds, regardless of whether or not the terminal device 1 exists nearby. Since the transmission distance of the signal of the key opening / closing device 2 is limited, when the terminal device 1 approaches within a predetermined distance from the key opening / closing device 2, the transmitted signal is detected by the terminal device 1, and the terminal device 1 A signal is received.

  When a signal is received from the key opening / closing device 2 in step S2, it is determined whether or not the received signal has a predetermined strength or higher (step S21). If the signal strength is weaker than the predetermined strength (NO in step S21), the process ends without starting the dedicated application. The reason that the strength of the received signal is weaker than the predetermined strength is that the distance between the key opening / closing device 2 and the terminal device 1 is large.

  If the intensity of the received signal is equal to or higher than the predetermined intensity (YES in step S21), the special application is activated without any particular operation (step S22), and the terminal identification information of terminal device 1 is the key opening / closing device. 2 (step S3). After step S3, the processing from step S4 shown in FIG. 4 is continued. The terminal identification information can be registered in advance in a dedicated application.

A user who intends to unlock the key possesses a terminal device that has been registered in advance as being the terminal device of the user, and the unlocking process is performed by approaching a distance that allows communication with the key opening / closing device 2. Be started.

  First, the key opening / closing device 2 periodically transmits a signal once every few seconds. The key opening / closing device 2 transmits a signal (step S31), and the terminal device 1 receives the signal (step S32). Since the distance of the signal is limited, the transmitted signal is received by the terminal device 1 when the terminal device 1 approaches within a predetermined distance from the key opening / closing device 2. By the way, by using a dedicated application in the terminal device 1, the process from receiving a signal from the key opening / closing device 2 in step S <b> 32 to transmitting the terminal identification information to the server device 1 in step S <b> 33 is automatically performed. It is also possible to execute it. Since this dedicated application can be automatically activated by receiving a signal from the key opening / closing device 2, it can be unlocked without operating the terminal device 1.

  Next, terminal identification information that can uniquely identify each terminal device is transmitted to the key opening / closing device 2 (step S33). When the terminal identification information is received by the key opening / closing device 2 (step S34), it is determined whether or not the received terminal identification information has the authority to unlock the key (that is, in the key opening / closing device 2 in advance). A determination is made as to whether or not it matches the registered terminal identification information (step S35).

  If it is determined that the terminal identification information received by the key opening / closing device 2 does not have the authority to unlock (NO in step S35), the process ends without being unlocked. On the other hand, when it is determined that the terminal identification information received by the key opening / closing device 2 has the authority to unlock (YES in step S35), unlocking permission information is set (step S36). ), Timing is started (step S37).

  Next, the key opening / closing device 2 transmits an activation signal for activating the authentication device 4 to the authentication device 4 (step S38). When the authentication device 4 receives the activation signal (step S39), the authentication device 4 is activated (step S40). In step S <b> 35, the authentication apparatus 4 is activated after it is determined that the terminal apparatus 1 has authority, whereby the battery of the authentication apparatus 4 can be held longer. Further, since the authentication device 4 is normally in the sleep state, it also serves as a countermeasure against hacking.

  Next, when the user's biometric information is received by the authentication receiving unit 47 (step S41), the biometric information is transmitted to the key opening / closing device 2 (step S42). Note that the authentication device 4 returns to a standby state when a predetermined time has elapsed since activation.

  When the biological information is received by the key opening / closing device 2 (step S43), the biological information is further transmitted to the terminal device 1 (step S44). Furthermore, biometric information is received by the terminal device 1 (step S45), and the biometric information is transmitted to the authentication server device 5 (step S46).

  When the authentication server device 5 receives the biometric information (step S47), it is determined whether or not the received biometric information matches the biometric information of the user registered in advance, that is, whether or not the user has authority. Determination is made (step S48). Regardless of whether or not the user has authority, the determination result of step S48 is transmitted to the terminal device 1 (step S49), and the determination result is received by the terminal device 1 (step S50).

  If the determination result received by the terminal device 1 is a determination result indicating that the user is not authorized (NO in step S51), it is determined that the determination result is not authorized. The message is displayed on the display screen 14 of the apparatus 1 and the process ends. On the other hand, if the determination result received by the terminal device 1 is that the user has authority (YES in step S51), an unlock signal is transmitted to the key opening / closing device 2 (step S51). S52).

  When the unlocking signal is received by the key opening / closing device 2 (step S53), the elapsed time from the start of timing in step S37 until the unlocking signal is received is within a predetermined time. It is determined whether or not unlocking permission information is set (step S54).

  If the elapsed time from the start of timing in step S37 until the unlock signal is received is within a predetermined time and unlock permission information is set (in step S54) YES), the key is opened by the key opening / closing unit 25 (step S55). Next, the unlocking permission information set in step S36 is canceled (step S56), and the timing started in step S37 is completed (step S57), whereby the unlocking process is completed.

  When the elapsed time from the start of timing in step S37 to the reception of the unlocking signal is outside a predetermined time, or when the unlocking permission information is released (step S54) In step S56 and S57, the unlocking permission information is canceled and the time counting is terminated.

  The key opening / closing device 2 can be installed on the indoor side of an existing door with a key. A thumb turn that opens and closes the lock is installed inside the door. By turning the thumb turn knob, the door can be locked and unlocked. When the unlock signal is received from the authentication device 4, the elapsed time from the start of timing in step S37 until the key opening / closing device 2 receives the unlock signal in step S53 is within a predetermined time. In some cases, the thumb-turn knob is rotated and unlocked by rotating the fixture fixed to the thumb-turn knob. Moreover, the authentication apparatus 4 is installed in the outdoor side and can receive a user's biometric information from the outdoor side. The authentication device 4 can perform wireless communication with the key opening / closing device 2.

  In the second embodiment of the present invention, the case where authentication is performed by the authentication server device 5 has been described. For example, the authentication is performed by the terminal device 1 or the key opening / closing device 2 without using the authentication server device 5. It is also possible.

  The electronic lock system of the present invention can be used without being limited to its use as long as it is a door or door on which a key is installed. For example, the present invention can be applied to doors of condominiums, detached houses, commercial buildings, safe doors, and the like.
