  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a schematic diagram showing a lock system 1 according to the present embodiment. The lock system 1 controls the opening and closing of the lock, and includes a lock 2, an additional device 3, and an external terminal 4.

  The lock 2 is provided on a door (not shown) and a door frame (not shown) of the room, and locks the door so that it cannot be opened. For example, the lock 2 includes a receiving seat 20 provided on the door frame and a lock body 21 provided on the door.

  The seat 20 is provided on the inner peripheral surface of the door frame and faces the lock body 21. A recess 200 that fits into a dead bolt 211 (described later) of the lock body 21 is provided on the surface of the seat 20 that faces the lock body 21.

The lock body 21 is provided in the vicinity of a door handle (not shown) at an end of the door on the swinging side, and has a thumb turn 210 and a dead bolt 211.
The thumb turn 210 is a knob arranged on the indoor side of the door, and is rotated by the user to switch between locking and unlocking. A key hole for inserting a key (not shown) for rotating the thumb turn is provided on the back side of the thumb turn 210, that is, the outdoor side.

  The dead bolt 211 is a columnar member that fits into the recess 200 of the seat 20, and appears and disappears from the lock body 21 by the rotation of the thumb turn 210. The dead bolt 211 protrudes from the lock body 21 and is inserted into the recess 200 of the seat 20 to lock the lock 2.

  The additional device 3 is a device that can be attached to the lock 2, and is attached to, for example, the indoor portion of the lock body 21. As an example, the additional device 3 has a recess 310 that fits into the interior portion of the lock body 21, and is attached to the lock body 21 by fitting the lock body 21 into the recess 310. Note that the additional device 3 may be fixed to the lock body 21 using a screw, an adhesive, or the like.

  A holding member 320 for holding the thumb turn 210 is provided on the bottom surface of the recess 310. A drive unit 31 that rotates the holding member 320 is interposed between the holding member 320 and the bottom surface of the recess 310. The drive unit 31 can switch between locking and unlocking by rotating the thumb turn 210 together with the holding member 320 by rotating the holding member 320 sandwiching the thumb turn 210.

  The additional device 3 as described above may be manufactured by the same manufacturer as the lock 2 or may be manufactured by a manufacturer different from the lock 2 so as to be compatible with the lock 2. Further, when the additional device 3 is manufactured by the same manufacturer as the lock 2, it may be formed integrally with the lock 2 in advance.

  The external terminal 4 is a terminal that can unlock the lock 2 in cooperation with the additional device 3. In the present embodiment, the case where the external terminal 4 is a smartphone is shown as an example. However, the external terminal 4 may be another terminal device capable of inputting and outputting data, such as a mobile phone and a PDA, or the lock 2 The key terminal having only the opening / closing function or the key terminal having the opening / closing function as a main function may be used.

  FIG. 2 is a block diagram showing the lock system 1 according to the present embodiment. As shown in this figure, the additional device 3 includes a detection unit 30, a determination device (control device) 5, and a drive unit 31.

  The detection unit 30 can detect a person in the vicinity of the door and transmits a detection signal indicating whether or not a person has been detected. Preferably, the detection unit 30 can detect a person within a radius of about 3 to 5 m from the lock 2, and more preferably a space locked by the lock 2 (also referred to as “lock space”. In the present embodiment). Can detect people in the indoor space. However, the detection unit 30 may be able to detect people inside and outside the lock space. In the present embodiment, the detection unit 30 is provided in the additional device 3 attached to the indoor side portion of the lock body 21 and is disposed in the lock space.

  The detection signal transmitted from the detection unit 30 is a signal having different values depending on whether a person is detected or not, such as a signal indicating the amount of change in temperature, and is received by the determination device 5. In the present embodiment, the case where the detection unit 30 is wired to the determination device 5 is shown as an example, but may be wirelessly connected.

  The above detection unit 30 includes at least one human sensor 300 that detects a person near the door. The human sensor 300 is attached to the outer surface (outer surface on the indoor side) of the additional device 3 as an example, and is attached to a position capable of detecting a person in the lock space, for example. As an example, as shown in FIG. 1 described above, the human sensor 300 is attached in the vicinity of the thumb turn 210 of the lock 2. Note that a plurality of human sensors 300 may be provided in different spaces in order to reliably detect a person in the lock space.

  The human sensor 300 may be attached to another part in the lock space instead of the additional device 3. For example, the human sensor 300 may be attached to the lock 2. Further, it may be attached to the indoor side surface of the door, the ceiling or wall in the lock space, or may be attached to the outside of the lock space such as the outdoor space. However, since the presence of the human sensor 300 outside the lock space may cause destruction, the human sensor 300 is preferably installed in a lock space such as an indoor space. When the human sensor 300 is not attached to the additional device 3, the detection unit 30 may transmit a detection signal to the determination device 5 through wireless communication.

The human sensor 300 described above includes an infrared sensor, a visible light sensor, an ultrasonic sensor, an image recognition device, a voice recognition device, a CO ₂ sensor, a touch sensor that detects contact with the lock 2, and the pressure provided on the ground. Including at least one of the sensors. Here, the infrared sensor may be a thermal type such as a pyroelectric type or a quantum type. The human sensor 300 is preferably a sensor that is non-contact and capable of sensing a wide range with low power consumption, and an infrared sensor, a visible light sensor, and an ultrasonic sensor are particularly preferable.

  The thermal infrared sensor detects infrared rays, receives the infrared rays, warms the sensor with heat, and detects a change in electrical properties caused by an increase in element temperature. The quantum infrared sensor detects an electrical phenomenon caused by light energy. Since the thermal infrared sensor detects a difference (time change) in electrical properties, there is a possibility that a stationary person cannot be detected. On the other hand, the quantum infrared sensor measures the absolute value, not the time change, and is preferable in terms of security without such a problem.

  Note that the detection unit 30 may detect a person using a GPS sensor built in the external terminal 4 instead of or in addition to the human sensor 300 as described above. The position information signal detected by the GPS sensor can be used as a detection signal indicating whether or not the user holding the external terminal 4 is detected within the vicinity of the door. Therefore, the position information signal detected by the GPS sensor is transmitted to the detection unit 30 to detect whether the user of the external terminal 4 is near the door.

The determination device 5 includes a storage unit 50, a communication unit 51, a determination unit 55, and a sensor activation unit 56.
The storage unit 50 stores programs and data for realizing various functions of the determination device 5. For example, the storage unit 50 stores a control program for controlling the lock 2 by the determination device 5. The storage unit 50 may store encrypted key information, an electronic signature, and other authentication information necessary for authenticating the external terminal 4.

The communication unit 51 includes a detection signal receiving unit 52 and a terminal signal receiving unit 53.
The detection signal receiving unit 52 receives the above-described detection signal from the detection unit 30, for example, a detection signal corresponding to the output of the human sensor 300.

  The terminal signal receiving unit 53 communicates with the external terminal 4 by wireless or wired. For example, the terminal signal receiving unit 53 receives an unlock request signal for requesting unlock from the external terminal 4. As an example, the unlock request signal may be a signal automatically transmitted from the external terminal 4 in response to the external terminal 4 approaching within a predetermined distance from the lock 2.

  Further, the terminal signal receiving unit 53 may further receive a forced unlocking request signal for requesting unlocking from the external terminal 4 regardless of whether or not a person is detected in the lock space. For example, the forced unlocking request signal may be a signal transmitted from the external terminal 4 in response to an operation from the user of the external terminal 4.

  As an example, the terminal signal receiving unit 53 includes a Bluetooth (registered trademark), a Wi-fi (communication distance of about 100 m), a class 2 (communication distance of about 10 m) and a class 3 (communication distance of about 1 m). The signal may be received from the external terminal 4 using any one of various communication standards such as infrared communication (communication distance less than about 1 m). Further, the terminal signal receiving unit 53 may receive a signal from the external terminal 4 via a provider via a Wi-fi antenna provided in the lock space. However, in view of the balance between security and convenience, the terminal signal receiving unit 53 preferably receives a signal within a range of about 1 m using the class 3 Bluetooth (registered trademark) standard. If the communication range is larger than this, the lock 2 may be unlocked when the user is far away from the door, and security may be lowered. In addition, if the communication range is smaller than this, even if the user reaches the door, the lock 2 may be kept waiting without being unlocked, which may reduce the convenience.

  The determination unit 55 determines whether or not to unlock the lock 2 based on the detection signal received by the detection signal reception unit 52 in response to the terminal signal reception unit 53 receiving the unlock request signal. For example, when using the human sensor 300 that measures an absolute value instead of a change over time, the determination unit 55 is based on the result of comparing the latest detection signal by the detection unit 30 with the previous detection signal. It may be determined whether or not a lock has been detected, and whether or not to unlock the lock may be determined based on the determination result.

  Then, when the detection signal indicates that no person is detected in the lock space, the determination unit 55 determines that the lock is unlocked in response to the unlock request signal. Further, when the detection signal indicates that a person has been detected in the lock space, the determination unit 55 determines that the lock is not unlocked even when the unlock request signal is received. When the terminal signal receiving unit 53 receives the forced unlocking request signal, the determination unit 55 determines that the lock 2 is unlocked regardless of the value of the detection signal. The determination contents of the opening / closing by the determination unit 55 will be described later with reference to FIG.

  Moreover, the determination part 55 may authenticate the transmission source external terminal 4 in response to the terminal signal receiving part 53 receiving the unlock request signal. Further, the determination unit 55 may determine whether or not to unlock the lock 2 only when the authentication is successful.

  When the detection unit 30 can detect a person outside the lock space, the determination unit 55 can lock even if the unlock signal is received when the detection signal indicates that there is no person outside the lock space. It may be determined that 2 is not unlocked. The outside of the lock space includes, for example, the space outside the door and in front of the door.

  The sensor activation unit 56 activates the human sensor 300 to detect a person according to a signal received from the external terminal 4 when the external terminal 4 is located within a predetermined range from the lock 2. In the present embodiment, the unlock request signal described above is used as a signal that triggers activation, but a beacon signal that the external terminal 4 transmits to establish communication with another device is used. Also good.

  The sensor activation unit 56 described above may transmit an activation signal to the human sensor 300 via a wired connection in the additional device 3. However, when the human sensor 300 is not attached to the additional device 3, the sensor activation unit 56 may transmit an activation signal to the human sensor 300 by wireless communication.

  The drive unit 31 unlocks the lock 2 by driving the thumb turn 210 of the lock 2 in response to the determination unit 55 determining the unlocking. For example, the drive unit 31 rotates the above-described holding member 320 (see FIG. 1) sandwiching the thumb turn 210 to rotate the thumb turn 210 together with the holding member 320 to unlock the lock 2. As an example, the drive unit 31 rotates the holding member 320 by a drive source such as a motor.

The external terminal 4 includes a storage unit 40, a control unit 41, a display unit 42, an operation unit 43, and a communication unit 45.
The storage unit 40 stores programs and data for realizing various functions of the external terminal 4. For example, the storage unit 40 stores a lock interlocking application 400 for unlocking the lock 2 by cooperating with the additional device 3. The lock interlocking application 400 may include encrypted key information, an electronic signature, and other authentication information necessary for unlocking the lock 2. When the external terminal 4 and the terminal signal receiving unit 53 of the additional device 3 communicate with each other via Bluetooth (registered trademark), pairing information may be included as the authentication information.

  The control unit 41 operates based on a program or the like stored in the storage unit 40 and controls each unit. The display unit 42 performs various displays based on control by the control unit 41. The operation unit 43 inputs various instructions according to user operations on the touch screen or the like.

  The communication unit 45 communicates with other devices by wireless communication. For example, the communication unit 45 transmits the above-described unlock request signal and forced unlock request signal for requesting unlocking of the lock 2 to the terminal signal receiving unit 53 in accordance with control by the control unit 41. The communication unit 45 may transmit a beacon signal for the external terminal 4 to establish communication with another device.

  Subsequently, a receivable range of a signal (for example, unlock request signal) by the terminal signal receiving unit 53 and a human detection range by the detection unit 30 will be described. FIG. 3 is a diagram illustrating a reach range of the unlock request signal and a human detection range by the detection unit 30.

  As shown in this figure, the detection unit 30 detects a person existing in a first range 101 determined in advance from the lock 2 in the lock space (the space on the right side in the figure). Here, although the magnitude | size of the 1st range 101 depends on the kind of the human sensitive sensor 300, it is preferable that it is about 3-5 m in radius. Such a detection range is realized by an infrared sensor.

  On the other hand, the terminal signal receiving unit 53 includes a second range 102 predetermined from the lock 2 included in the first range 101 in the lock space and a third range predetermined from the lock 2 outside the lock space. An unlock request signal can be received from the external terminal 4 located at 103. Thus, since the first range 101 that is a human detection range includes the second range 102 that is the reception range of the unlock request signal, the first range 101 is opened when there is a user of the external terminal 4 in the lock space. When the lock request signal is received, the user is always in the first range 101. The sizes of the second range 102 and the third range 103 depend on the communication standard between the external terminal 4 and the terminal signal receiving unit 53, but are preferably about 1 m as described above.

  Next, the opening / closing determination by the determination unit 55 will be described. FIG. 4 is a diagram illustrating the determination contents of the opening / closing by the determination unit 55.

  As shown in this figure, when the determination unit 55 has not received the unlock request signal from the external terminal 4, it determines that the lock 2 is not unlocked regardless of the value of the detection signal from the detection unit 30. . In the present embodiment, as the unlock request signal, for example, a signal that is automatically transmitted when the external terminal 4 approaches within a predetermined distance from the lock 2 is used. In this case, the lock 2 is prevented from being unlocked when the external terminal 4 is separated from the lock 2.

  In addition, when receiving the unlock request signal from the external terminal 4, the determination unit 55 determines that the lock 2 is unlocked when the detection signal from the detection unit 30 does not indicate detection of a person in the lock space. . Therefore, when the external terminal 4 approaches the lock 2 and the unlock request signal is received and there is no person in the lock space, that is, the user seems to have approached the lock 2 from the outside of the door. In that case, the lock 2 is unlocked.

  Further, when receiving the unlock request signal from the external terminal 4, the determination unit 55 determines that the lock 2 is not unlocked when the detection signal from the detection unit 30 indicates human detection in the lock space. To do. Therefore, when the external terminal 4 approaches the lock 2 and the unlock request signal is received and there is a person in the lock space, that is, the user seems to have approached the lock 2 from the inside of the door. In such a case, the lock 2 is prevented from being unlocked. For example, when the second range 102 that is the reception range of the unlock request signal is included in the first range 101 that is the human detection range, the user who approaches the lock 2 from the inside of the door is always the first. Since it is within the range 101 and is detected by the detection unit 30, the unlocking of the lock 2 is reliably prevented. Thereby, when the user is in the lock space and does not intend to go out, the lock 2 can be prevented from being unlocked without permission.

  Further, when receiving the forced unlocking request signal, the determination unit 55 determines to unlock the lock 2 regardless of the value of the detection signal from the detection unit 30. Therefore, when the forced unlocking request signal is received, the lock 2 is unlocked regardless of the presence or absence of a person in the lock space. Thereby, when the user intends to go out and approaches the lock 2 from the inside of the door, the lock 2 can be forcibly opened. Also, when the user approaches the lock 2 from the outside of the door but there is another person in the lock space and the unlocking of the lock 2 is prevented, the lock 2 is forcibly unlocked. be able to.

  Next, the operation of the lock system 1 will be described. FIG. 5 is a flowchart showing the operation of the lock system according to the present embodiment. The lock system 1 controls the unlocking of the locked lock 2 by executing the processing from S100 to S170. In the following description, the external terminal 4 is set to automatically unlock the lock 2, and thus a beacon signal is intermittently transmitted to automatically establish communication with the additional device 3. The explanation will be given.

  First, in S100 and S101 in FIG. 5, communication is established between the communication unit 51 of the additional device 3 and the communication unit 45 of the external terminal 4. For example, when the user carrying the external terminal 4 approaches the lock 2 to the inside of the second range 102 or the third range 103 described above, a beacon signal transmitted intermittently from the external terminal 4 is transmitted to the additional device 3. The communication unit 51 receives the communication and establishes communication.

  Next, in S115, the communication unit 45 of the external terminal 4 transmits an unlock request signal. This unlocking request signal is received by the terminal signal receiving unit 53 of the additional device 3 and provided to the determination unit 55 and the sensor activation unit 56.

  Next, in S120, the determination unit 55 authenticates the external terminal 4 that is the transmission source of the unlock request signal in response to the reception of the unlock request signal. For example, the determination unit 55 may authenticate the external terminal 4 by determining whether or not the authentication information transmitted from the external terminal 4 matches the authentication information stored in the storage unit 50. . The authentication information from the external terminal 4 may be transmitted together with the unlock request signal. When the external terminal 4 and the terminal signal receiving unit 53 of the additional device 3 communicate with each other using Bluetooth (registered trademark) and pairing information is used as authentication information, the determination unit 55 establishes communication in S100. Sometimes the external terminal 4 may be authenticated. If the authentication is successful, the determination unit 55 may proceed to the next process, and if the authentication fails, the determination unit 55 may transmit an authentication failure message to the external terminal 4 and terminate the process.

  If the authentication is successful, the sensor activation unit 56 transmits an activation signal to the detection unit 30 in S125, and the detection unit 30 is activated in S130. Thereby, the human sensor 300 of the detection unit 30 detects a person in the lock space. For example, the human sensor 300 detects a person in the first range 101 only within a predetermined time. The detection unit 30 transmits a detection signal indicating whether or not a person has been detected to the determination unit 55. Note that the sensor activation unit 56 may transmit an activation signal to the detection unit 30 in response to reception of a beacon signal from the external terminal 4. In this case, the detection unit 30 is activated at a timing earlier than the activation in response to the reception of the unlock request signal, and the processing of S125 to S135 described later can be performed before the above-described S120.

  Next, in S135, the determination unit 55 receives the detection signal, and in S140, it is determined whether or not to unlock the lock 2. For example, when the detection unit 30 is activated by receiving an unlocking request signal, as shown in the second line of FIG. 4 described above, the determination unit 55 does not detect human detection in the lock space. In addition, it is determined that the lock 2 is unlocked, and it is determined that the lock 2 is not unlocked when human detection is indicated in the lock space. Further, when the detection unit 30 is activated by receiving a beacon signal, the same determination is performed after the unlock request signal is received.

  Here, as the human sensor 300, when using a quantum infrared sensor or the like that measures an absolute value instead of a temperature difference (time change) in the observation target range, if the temperature in the lock space is high, Since the temperature difference between the person in the lock space and the surrounding structure is small, the person may not be detected. In such a case, if a measurement result at the time of startup is used as a comparison target for determining the presence or absence of a person and a difference from the latest measurement result is taken, the detection accuracy of the person can be improved. Further, if the human sensor 300 is intermittently activated and the measurement result at the previous activation is used, the intermittent activation is not performed, that is, at the time of activation in response to reception of the previous unlock request signal or beacon signal. Compared with the case where the measurement result is used as a comparison target, the measurement conditions can be approximated between the current measurement and the measurement of the comparison target, and the human detection accuracy can be further improved.

  Therefore, when a quantum infrared sensor or the like that measures an absolute value instead of a difference (time change) is used as the human sensor 300, the determination unit 55 detects the human sensor 300 that is intermittently activated. The signal is accumulated and stored in the storage unit 50. In S135, it is determined whether or not a person is detected in the lock space based on the result of comparing the latest detection signal and the previous detection signal (for example, the previous detection signal). You may judge. In this case, the sensor activation unit 56 activates the human sensor 300 intermittently in addition to starting the human sensor 300 in response to the unlock request signal and the forced unlock request signal. When the temperature in the lock space is low (for example, when the temperature is equal to or lower than the threshold), the sensor activation unit 56 may increase the activation interval of the human sensor 300 as compared to the case where the temperature is high. There is no need to perform intermittent activation.

  When it is determined that the unlocking is performed in S140 (S140; Yes), that is, when the unlocking request signal is received and there is no person in the lock space, the determination unit 55 drives the unlocking signal in S145. It transmits to the part 31. In S170, the drive unit 31 drives the thumb turn 210 of the lock 2 to unlock the lock 2, and the lock system 1 ends the process.

  When it is determined in S140 that the unlocking is not performed (S140; No), that is, when the unlocking request signal is received and there is a person in the lock space, the determination unit 55 cannot unlock in S150. Is transmitted to the external terminal 4 via the communication unit 51. This unlocking notification is received by the control unit 41 of the external terminal 4.

  Next, in S155, the control unit 41 of the external terminal 4 displays a message notifying that the unlocking is impossible and an instruction input receiving unit (for example, a button) for instructing the compulsory unlocking of the lock 2. 42 is displayed. And according to operation with respect to this button, the control part 41 transmits the forced unlocking request signal to the additional apparatus 3 from the communication part 45. FIG. For example, when there is a family in the lock space, the user operates a button to transmit a forced unlocking request signal. In addition, when there is no operation with respect to a button, the lock | rock system 1 may complete | finish a process. For example, if the user does not recognize that there is a person in the lock space, for example, if it is considered that there is a suspicious person in the lock space, the user will postpone unlocking the lock 2 Also good. Further, the user may unlock the lock 2 by inserting a key into the keyhole without performing an operation on the button.

  Next, in S <b> 160, the determination unit 55 of the additional device 3 determines to unlock the lock 2 in response to reception of the forced unlocking request signal, and transmits the unlocking signal to the drive unit 31. In S170, the drive unit 31 drives the thumb turn 210 of the lock 2 to unlock the lock 2, and the lock system 1 ends the process.

  Subsequently, a display screen displayed on the external terminal 4 in the above-described operation will be described. FIG. 6 is a diagram illustrating an example of a display screen of the external terminal. The external terminal 4 may display the determination result by the determination device 5 on the display unit 42.

  The example of FIG. 6 shows an example of a display screen when the determination device 5 determines that the lock 2 cannot be unlocked as a result of the presence of a person in the lock space. The user can forcibly unlock the lock 2 by operating a button displayed as “Forced unlocking”.

  In addition, in said description, although demonstrated that the additional apparatus 3 provided with the detection part 30, the drive part 31, and the determination apparatus 5 was attached to the lock 2, the structure of the lock system 1 is not limited to this. For example, as shown in FIG. 7, only the drive unit 31 and the determination device 5 may be attached to the lock 2, or the lock device 250 may be configured by being incorporated in the lock 2. In this case, the detection unit 30 may be attached to the indoor side surface of the door, the ceiling in the lock space, the wall, or the like apart from the lock 2 or the like, or may be attached to the lock device 250. . Or the detection part 30 may be arrange | positioned out of lock space, such as the surface outside the door of a door, and the wall outside lock space, for example. However, since the detection unit 30 may be destroyed by a suspicious person when arranged outside the lock space, the detection unit 30 is preferably arranged within the lock space.

  Moreover, although the determination apparatus 5 was demonstrated as determining whether the lock 2 was unlocked, in addition to this, the external terminal 4 was carried by associating a plurality of external terminals 4 with different IDs. A plurality of users may be managed for each individual, and the behavior history of each user may be recorded. For example, the determination device 5 may identify the unlock request signal transmitted from each of the plurality of external terminals 4 and store the reception history in the storage unit 50 as the action history of each user.

  Further, when the unlocking request signal is received, the determination device 5 detects that a person is not detected in the lock space and the lock 2 is unlocked, and then a person is detected in the lock space. The user of the external terminal 4 that is the transmission source of the unlock request signal may be stored in the storage unit 50, assuming that the user has entered the lock space. Further, when a person is detected in the lock space when the unlock request signal is received, the determination device 5 indicates that the user of the external terminal 4 that has transmitted the unlock request signal is in the lock space. You may memorize | store in the memory | storage part 50 as continuing living.
