Description

  The present invention relates to a technique for automatically locking and unlocking doors (entrance doors and the like) of doorways such as buildings.

  In recent years, a system that automatically locks and unlocks a door (such as an entrance door) of an entrance / exit of a building or the like using a mobile terminal such as a smartphone has been proposed and has started to spread. In the system as described above, the portable terminal is used as a virtual key, and it is not necessary to use a physical key as in the conventional case, so that convenience for the user is improved. In addition, for example, from the standpoint of the rental housing owner, it is easy to restrict the use of virtual keys or change them to something else. There is also an advantage that there is no need to exchange. For example, Japanese Unexamined Patent Application Publication No. 2012-207452 (Patent Document 1) discloses a conventional technique for opening and closing a key using a portable terminal.

  By the way, in many cases, the direction in which the thumb turn is rotated at the time of locking or unlocking differs depending on the opening direction of the door (opening to the right or opening to the left). It is necessary for the user to grasp the opening direction of the thumb or the rotation direction of the thumb turn and to accurately set the information in the system. However, the user may not always be able to accurately grasp and set the opening direction of the door, and may cause misunderstandings and input errors. In that case, since unlocking and locking cannot be performed correctly, it is necessary to identify the cause and perform setting again, which increases labor. In addition, since the direction and size for rotating the thumb turn during the operation of the system are determined, it is necessary to precisely match the direction of the structure that rotates the thumb turn when the system is installed. For this reason, for the user who uses the system, it takes much time to install the system and it is not convenient.

Is called.

  Specifically, the authentication processing unit 11 requests the mobile terminal 200 to transmit authority information previously given to the mobile terminal 200, and the authority information returned from the mobile terminal 200 is stored in the memory 20. If the mobile terminal 200 matches the authority information, it is determined that the mobile terminal 200 has the authority to unlock / lock.

  When a command (instruction) for instructing unlocking or locking is transmitted from the portable terminal 200 that has been authenticated by the authentication processing unit 11 as having authority, the opening / closing control unit 12 receives the transmitted command (unlocking / locking). ) To give the thumb turn opening / closing mechanism 22 an operation instruction command. Further, the opening / closing control unit 12 gives an operation instruction command for “locking” to the thumb turn opening / closing mechanism 22 when a predetermined time has elapsed after giving an operation instruction command for “unlocking” to the thumb turn opening / closing mechanism 22. .

  Based on the detection result of the rotational position sensor 23 and the information transmitted from the mobile terminal 200, the thumb turn state detector 13 determines the position of the thumb turn 400 at the time of locking and unlocking, the operation from the locking to unlocking, and The rotation direction of the thumb turn 400 in each of the reverse operations is detected. Information on the detected position and rotation direction of the thumb turn 400 is written into the memory 20 by the thumb turn state detector 13 and stored in the memory 20.

  The door opening / closing direction determination unit 14 determines the position of the door on which the key opening / closing device 100 is installed based on each position and rotation direction information of the thumbturn 400 detected and locked by the thumbturn state detector 13. The opening direction (right opening or left opening) is determined. In the present embodiment, for example, if the rotation direction of the thumb turn 400 at the time of locking is clockwise, the door opening direction is determined to be “right open”, and if the rotation direction of the thumb turn 400 at the time of locking is counterclockwise, the door Is determined to be “left open”.

  The command processing unit 32 uses the authority information acquired from the server 300 by the authentication processing unit 31 to transmit a command (command) for instructing the unlocking or locking of the thumb turn 400 to the key opening / closing device 100. Do. In addition, the command processing unit 32 transmits the authority information stored in the memory 40 to the key opening / closing device 100 together with the unlock command transmission or prior to the command transmission.

  When the key opening / closing device 100 is installed, the initial setting processing unit 33 performs processing for setting the position of the thumbturn 400 at the time of locking and unlocking by the user's operation. Specifically, the initial setting processing unit 33 displays a “locking position” setting button, for example, as shown in FIG. 4A when setting the position at the time of locking. When the user presses this setting button after turning the thumbturn 400 to the “locked” position, information indicating that the current position is set as the “locked” position is transmitted to the key opening / closing device 100.

  Similarly, when the position setting at the time of unlocking is performed, the initial setting processing unit 33 displays a “unlocked position” setting button as shown in FIG. 4B, for example. When the user presses this setting button after turning the thumbturn 400 to the “unlocked” position, information indicating that the current position is set as the “unlocked” position is transmitted to the key opening / closing device 100. . Information transmission from the initial setting processing unit 33 to the key opening / closing device 100 is performed via the short-range communication unit 41.

  FIG. 5 is a schematic diagram showing the installation position of the key opening / closing device. FIG. 6 is a longitudinal sectional view showing the configuration of the thumb turn opening / closing mechanism of the key opening / closing device. The key opening / closing device 100 can be attached to a thumb turn 400 located inside (room side) of a door (door) 410, for example. The key opening / closing device 100 is detachably attached to the door 410 using, for example, a magnet. The key opening / closing device 100 includes, for example, a thumb turn 400 and a casing 160 that covers the periphery thereof.

  The key opening / closing device 100, as the thumb turn opening / closing mechanism 22, rotates the thumb turn rotating section 170 for rotating the thumb turn 400, the rotation driving mechanism 171 for rotating the thumb turn rotating section 170 by the power of the drive source, and manually rotating the thumb turn rotating section 170. A manual rotation unit 172, a power supply unit 173, and the like are provided in the housing 160. Further, the key opening / closing device 100 has a clutch mechanism 120 capable of interrupting the transmission of power between the motor 190 of the rotation drive mechanism 171 and the thumb-turn rotation unit 170 when the thumb-turn rotation unit 170 is rotated by the manual rotation unit 172. doing

  The thumb-turn rotating unit 170 includes, for example, a substantially cylindrical columnar part 180 and a leg part 181 that protrudes rearward (left side in FIG. 6) from the bottom surface of the cylindrical part 180.

  The cylindrical part 180 has, for example, a large-diameter part 183 on the rear side and a small-diameter part 184 on the front side (right side in FIG. 6). A groove 185 into which the convex portion 101 of the rotation driving member is fitted is formed on the front surface of the large diameter portion 183. The groove portion 185 is formed in an arc shape with the rotation axis of the thumb turn rotating portion 170 as the center. The inner angle of the arc of the groove 185 is, for example, about 270 ° (3/2 × π (rad)).

  For example, four leg portions 181 are provided on the same circumference centering on the rotation axis of the cylindrical portion 180, and groove portions having different widths are formed in a cross shape by the four leg portions 181. The thumb turn rotating unit 170 can rotate the thumb turn 400 by holding and rotating the thumb turn 400 between the legs 181.

  The ring-shaped magnet 130 is an annular permanent magnet and is provided along the outer circumferential surface of the small-diameter portion 184 of the cylindrical portion 180. The ring-shaped magnet 130 is configured to have one or more pairs of N poles and S poles adjacent to each other on the outer peripheral surface, for example. A plurality of Hall elements 131 are arranged around the ring-shaped magnet 130. The ring-shaped magnet 130 and the plurality of hall elements 131 constitute the rotational position sensor 23 described above. The configuration of the rotational position sensor 23 is not limited to this, and various known techniques can be applied.

  The manual rotation unit 172 is formed in a columnar shape or a disk shape, for example, and is fixed to the front side of the columnar portion 180 of the thumb turn rotation unit 170. The manual rotation unit 172 is disposed in the opening 160 b provided in the front surface 160 a of the housing 160 and protrudes to the front side of the housing 160. The thumb turn rotating unit 170 can be manually rotated by the user holding and rotating the portion of the manual rotating unit 172 protruding from the housing 160 by hand. The manual rotating unit 172 may have a knob such as a thumb turn.

  The rotation drive mechanism 171 includes, for example, a motor 190 as a drive source that is driven by remote operation, a rotation drive member 191 that is provided on the same axis as the thumb turn rotation unit 170 and can be locked to the thumb turn rotation unit 170, and power of the motor 190. A transmission mechanism 192 for transmitting to the rotation drive member 191 is provided.

  The rotation drive member 191 is formed in a ring shape, and is fitted into the small diameter portion 184 of the cylindrical portion 180 of the thumb turn rotating portion 170. The rotation drive member 191 has teeth on the outer peripheral surface and constitutes a gear. The rotation drive member 191 includes an arcuate convex portion 101 centered on the rotation axis on the bottom surface side. The inner angle of the arc of the convex portion 101 is formed, for example, at about 180 °.

  The power supply unit 173 includes one or a plurality of batteries. The power supply unit 173 supplies power to the motor 190, the control unit 10, and the like.

  FIG. 7 is a flowchart showing an operation procedure of the key opening / closing device. For example, after the key opening / closing device 100 is installed on the door 410, this operation is started by the user operating the mobile terminal 200, which is an external device, and the mobile terminal 200 and the key opening / closing device 100 operating. Here, the locking position is set first, and then the unlocking position is set, but the order may be reversed.

  The user turns the thumb turn 400 using the manual rotation portion 172 of the key opening / closing device 100 in accordance with an image (see FIG. 4A) displayed on the display portion 43 of the portable terminal 200, whereby the thumb turn 400 is “locked. When the input unit 44 detects that the setting button displayed on the display unit 43 has been pressed, information indicating that the current position has been set as the “locked” position. (First information) is transmitted from the portable terminal 200 to the key opening / closing device 100.

  At this time, the thumb turn state detector 13 determines whether or not the lock position of the thumb turn 400 is set based on the information transmitted from the initial setting processor 23 of the mobile terminal 200 (step S11). While the information regarding the position setting of “locking” is not transmitted (step S11; NO), the determination of step S11 is repeated.

  When information related to the position setting of “locking” is transmitted (step S11; YES), the thumb-turn state detection unit 13 based on the detection result of the rotational position sensor 23, that is, the current position of the thumb-turn 400, that is, the position corresponding to the locking time. And information indicating the position is stored in the memory 20 (step S12).

  Next, the thumb turn 400 is rotated by the user using the manual rotation unit 172 of the key opening / closing device 100 according to an image (see FIG. 4B) displayed on the display unit 43 of the mobile terminal 200. Is set to a position corresponding to “unlocked” and then the input unit 44 detects that the setting button displayed on the display unit 43 has been pressed, the current position is set as the “unlocked” position. Information (second information) indicating this is transmitted from the portable terminal 200 to the key opening / closing device 100.

  At this time, the thumb turn state detector 13 determines whether the unlock position of the thumb turn 400 is set based on the information transmitted from the initial setting processor 23 of the mobile terminal 200 (step S13). While the information regarding the position setting for “unlocking” is not transmitted (step S13; NO), the determination in step S13 is repeated.

  When information related to the position setting of “unlocking” is transmitted (step S13; YES), the thumb-turn state detection unit 13 responds to the current position of the thumb-turn 400 based on the detection result of the rotational position sensor 23, that is, unlocking. The position to be detected is detected, and information indicating the position is stored in the memory 20 (step S14).

  Next, the thumb turn state detection unit 13 determines the rotation direction at the time of locking and unlocking of the thumb turn 400 based on the position information corresponding to the detected “locking” and “unlocking” of the thumb turn 400. The information indicating the rotation direction is obtained and stored in the memory 20 (step S15).

  FIG. 8 is a schematic diagram for explaining a method for obtaining the rotation direction of the thumb turn in step S15. For example, as shown in FIG. 8A, the upper position of the thumb turn 400 at the time of unlocking is the 0 ° direction (12 o'clock direction), and the upper position of the thumb turn 400 at the time of locking is the 90 ° direction (3 o'clock direction). Suppose that In this case, it can be seen that the rotation direction when the thumb turn 400 is locked is “clockwise”, and the rotation direction when the thumb turn 400 is unlocked is the opposite “counterclockwise”. Further, as shown in FIG. 8B, the upper position of the thumb turn 400 at the time of unlocking is the 0 ° direction (12 o'clock direction), and the upper position of the thumb turn 400 at the time of locking is the 270 ° direction (9 o'clock direction). Suppose that In this case, it can be seen that the rotation direction when locking the thumb turn 400 is “counterclockwise”, and the rotation direction when unlocking the thumb turn 400 is the opposite “clockwise rotation”. The rotation direction obtained and stored here is used for operation control when the thumb turn 400 is automatically activated by the key opening / closing device 100 by an operation using the portable terminal 200 or the like.

  In order to make the explanation easier to understand, the unlocking position is set to 0 ° and the locking position is set to 90 ° or 270 °. However, these positions are arbitrary, and the unlocking and locking values The position may be any position. For this reason, it becomes possible to give a freedom degree to the direction at the time of installation of the key opening / closing apparatus 100.

  Next, the door opening / closing direction determination unit 14 determines the opening direction of the door 410 based on the rotation direction of the thumb turn 400 obtained in step S15, and stores the determination result in the memory 20 (step S16). For example, if the rotation direction of the thumb turn 400 at the time of locking is “clockwise”, it can be determined that the door 410 is opened to the right. If the rotation direction of the thumb turn 400 at the time of locking is “counterclockwise”, the door 410 is left. It can be determined that it is open.

  According to the embodiment as described above, in the device that automatically locks and unlocks the door, it is possible to autonomously detect and set the rotation direction of the thumb turn. In addition, it is possible to provide a degree of freedom in the direction of system installation.

  The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the said embodiment is only a mere illustration in all points, and is not interpreted limitedly.

  For example, in the embodiment described above, authority information is given to the mobile terminal 200 from the server 300, and authentication processing between the key opening / closing device 100 and the mobile terminal 200 is performed using this authority information. Instead, identification information that can specify the authorized mobile terminal 200 may be stored in the memory 20 of the key opening / closing device 100 in advance, and the presence / absence of the authority of the mobile terminal 200 may be determined using the identification information.

  In the above-described embodiment, the rotation direction at the time of operation of the thumb turn 400 is obtained based on the respective positions when the thumb turn 400 is unlocked and locked. However, the rotation direction sensor 23 may directly obtain the rotation direction. . In this case, for example, the initial setting processing unit 33 of the mobile terminal 200 displays an image indicating “Please unlock from the locked state”, and when the user presses the setting start button, the rotation position sensor 23 The rotation direction may be detected by the thumb turn state detector 13 based on the output.
