  Drawing 1 is a figure showing the schematic structure of the operation control system of one embodiment. The operation control system shown in the figure is a system for autonomously opening and closing a key (object) installed on a door of a residence or an office using a portable terminal possessed by a user. In this operation control system, a key opening / closing device 100 for unlocking and locking by rotating a thumb turn 400 provided on a door key, a mobile terminal 200 such as a smartphone possessed by a user, and various information to the mobile terminal 200 Or a server 300 that performs processing such as providing a right to open / close a key. The portable terminal 200 and the server 300 are connected to each other via a communication network N so as to be able to communicate with each other.

  The key opening / closing device 100 is installed in association with the thumb turn 400 of the door, and includes a mechanism for rotating the thumb turn 400. Here, the thumb turn 400 has, for example, a plate-shaped knob, and operates the lock built in the door by rotating the knob. For example, a state in which the knob portion of the thumb turn 400 is positioned substantially vertically corresponds to “unlocking”, and a state in which the knob portion is positioned substantially horizontally corresponds to “locking”. The key opening / closing device 100 automatically rotates such thumb turn 400. In addition, as a specific configuration of such a key opening / closing apparatus 100, various known techniques (for example, see Japanese Patent Application Laid-Open No. 2002-168014) can be used.

  The portable terminal 200 is possessed by the user, and has a function of performing communication via a communication line such as the Internet and a short-range wireless communication function such as Bluetooth (registered trademark). In the present embodiment, a smartphone is assumed as the mobile terminal 200, but any terminal having a communication function such as a mobile phone, a PHS, a personal computer (PC), a notebook PC, a personal digital assistant (PDA), or a home game machine may be used. Applicable.

  The server 300 is for performing various processes such as providing various types of information to the portable terminal 200 or giving authority for key opening and closing. The server 300 is configured by, for example, a computer having high arithmetic processing capability, and is configured by executing a predetermined server program on the computer.

  The communication network N is configured to include a communication network that can perform information communication between the mobile terminal 200 and the server 300. The communication network N may be any of, for example, the Internet, a LAN, a dedicated line, a telephone line, a corporate network, a mobile communication network, other communication lines, a combination thereof, or is it wired or wireless? It doesn't matter.

  FIG. 2 is a block diagram showing a configuration of the key opening / closing device 100. As illustrated, the key opening / closing device 100 includes a control unit 10, a memory 20, a short-range communication unit 21, and a thumb turn opening / closing mechanism 22.

  The control unit 10 is configured by executing a predetermined operation program in a computer system including, for example, a CPU, and includes a beacon transmission unit 11, an authentication processing unit 12, and an opening / closing control unit 13 as functional blocks. .

  The beacon transmission unit 11 performs processing for transmitting a specific radio wave signal (beacon signal) toward the mobile terminal 200 by the short-range communication unit 21. This radio signal is transmitted periodically, for example, every several hundred milliseconds, and includes identification information for identifying the key opening / closing device 100 from other devices.

  The authentication processing unit 12 performs a process (authentication process) for confirming whether the portable terminal 200 has the authority to unlock and lock the key. In this authentication process, for example, authority information, which is information indicating that the mobile terminal 200 is permitted to perform key unlocking, is stored in the memory 20 in advance, and is performed using the identification information. Is called. Specifically, the authentication processing unit 12 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 the command (command) instructing the unlocking or locking is transmitted from the portable terminal 200 that has been authenticated by the authentication processing unit 12 as having authority, the opening / closing control unit 13 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 13 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. .

  The memory 20 is a storage unit (for example, a non-volatile memory) connected to the control unit 10 and stores an operation program executed by the control unit 10 and various data. The memory 20 stores information (such as authority information) necessary for processing in the authentication processing unit 12.

  The short-range communication unit 21 is connected to the control unit 10 and performs processing related to information communication at a relatively short distance between the control unit 10 and the mobile terminal 200. In the present embodiment, the short-range communication unit 21 performs information communication based on a known Bluetooth standard.

  The thumb turn opening / closing mechanism 22 is attached to the thumb turn 400, and the thumb turn 400 is moved to positions corresponding to the states of “locked” and “unlocked” in accordance with an operation instruction command given from the opening / closing control unit 13 of the control unit 11. Operate.

  FIG. 3 is a schematic diagram showing an installation position of the lock opening / closing device. FIG. 4 is a longitudinal sectional view showing the structure of the thumb turn opening / closing mechanism of the lock opening / closing device. The lock opening / closing device 100 can be attached to a thumb turn 400 located inside (room side) of a door (door) 410, for example. The lock opening / closing device 100 is detachably attached to the door 410 by, for example, a magnet. The lock opening / closing device 100 includes, for example, a thumb turn 400 and a casing 160 that covers the periphery thereof.

  The lock 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.

  The thumb turn rotating unit 170 includes, for example, a substantially cylindrical columnar part 180 and a leg 181 that protrudes rearward (left side in FIG. 3) from the bottom surface of the cylindrical part 180.

  The cylindrical portion 180 has, for example, a large-diameter portion 183 on the rear side and a small-diameter portion 184 on the front side (right side in FIG. 3). 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 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 convex portion 101 is fitted in the arc-shaped groove 185 of the thumb turn rotating portion 170, whereby the rotation driving member 191 can be locked to the thumb turn rotating portion 170 in the rotation direction.

  The transmission mechanism 192 includes a plurality of gears, for example. For example, the transmission mechanism 192 includes a gear 110 attached to the shaft of the motor 190 and a gear 111 that meshes with the gear of the rotation drive member 191. When the motor 190 is driven, the gears 110 and 111 are rotated, and the rotation driving member 191 is rotated.

  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. 5 is a block diagram illustrating a configuration of the mobile terminal 200. As illustrated, the mobile terminal 200 includes a control unit 30, a memory 40, a short-range communication unit 41, and a communication unit 42.

  The control unit 30 is configured by executing a predetermined operation program in a computer system including, for example, a CPU, and includes a radio wave intensity detection unit 31 and a command processing unit 32 as functional blocks.

  The radio wave intensity detector 31 detects the radio wave intensity of the radio wave signal transmitted from the key opening / closing device 100 and received by the short-range communication unit 41.

  The command processing unit 32 performs a process of transmitting a command (command) instructing the unlocking or locking of the thumb turn 400 to the key opening / closing device 100. Based on the radio wave intensity detected by the radio wave intensity detection unit 31, the command processing unit 32 according to the present embodiment transmits an unlock command when the radio wave intensity is greater than a preset first threshold value. Further, the command processing unit 32 transmits a locking command based on the radio wave intensity detected by the radio wave intensity detection unit 31 when the radio wave intensity becomes smaller than a preset second threshold value. Further, the command processing unit 32 transmits the authority information stored in the memory 40 to the key opening / closing device 100 together with the command transmission or prior to the command transmission.

  The memory 40 is a storage unit (for example, a non-volatile memory) connected to the control unit 30 and stores an operation program executed by the control unit 30 and various data. For example, the memory 40 stores authority information previously given from the server 300 to the mobile terminal 200.

  The short-range communication unit 41 is connected to the control unit 30 and performs processing related to information communication at a relatively short distance between the control unit 30 and the key opening / closing device 100. In the present embodiment, the short-range communication unit 41 performs information communication based on a known Bluetooth standard.

  The communication unit 42 is connected to the control unit 30 and performs processing necessary for the control unit 30 to perform information communication with the server 300 via the network N.

  In the present embodiment, the beacon transmission unit 11 and the short-range communication unit 21 correspond to the “transmission unit”, the opening / closing control unit 13 and the thumb-turn opening / closing mechanism 22 correspond to the “operation control unit”, and the radio wave intensity detection unit. 31 and the short-range communication unit 41 correspond to a “detection unit”, and the command processing unit 32 and the short-range communication unit 41 correspond to a “transmission unit”.

  FIG. 6 is a conceptual diagram for explaining the first threshold value and the second threshold value used in the command processing unit. The command processing unit 32 of the mobile terminal 200 is configured such that the radio wave intensity of the radio signal transmitted from the key opening / closing device 100 and received by the mobile terminal 200 is greater than a preset first threshold when the mobile terminal 200 approaches the key opening / closing device 100. When it gets bigger, it generates and sends an unlock command. The first threshold value at this time is set according to the radio field intensity when the mutual distance between the key opening / closing device 100 and the portable terminal 200 approaches a predetermined unlocking distance (for example, several tens of centimeters).

  Similarly, the command processing unit 32 of the mobile terminal 200 is configured such that the mobile terminal 200 moves away from the key opening / closing device 100 and the radio wave intensity of the radio wave signal transmitted from the key opening / closing device 100 and received by the mobile terminal 200 is preset. When it becomes smaller than the threshold, a lock command is generated and transmitted. The second threshold value at this time is set according to the radio field intensity when the mutual distance between the key opening / closing device 100 and the portable terminal 200 is a predetermined locking distance (for example, several meters).

  Here, the first threshold and the second threshold may be the same value, but it is preferable to set the first threshold relatively larger than the second threshold. As a result, the mobile terminal 200 is not unlocked unless the situation where the mobile terminal 200 is close to the key opening / closing device 100 to some extent, in other words, the situation in which the user holding the mobile terminal 200 can reliably determine that the user has the intention to unlock. be able to. In addition, it is possible to prevent the mobile terminal 200 from being locked unless the mobile terminal 200 is clearly moved away from the key opening / closing device 100, in other words, the user who has the mobile terminal 200 can be surely determined to have the intention of locking. . That is, it is possible to prevent the unlocking and locking from being repeated unnecessarily frequently.

  FIG. 7 is a flowchart showing an operation procedure of the mobile terminal. Here, it is assumed that the mobile terminal 200 has been granted authority information from the server 300 in advance, and that authority information is stored in the memory 42 of the mobile terminal 200.

  The command processing unit 32 determines whether or not the radio field intensity detected by the radio field intensity detection unit 31 is greater than the first threshold (Step S11).

  When the radio wave intensity is equal to or lower than the first threshold (step S11; NO), the command processing unit 32 determines whether the radio wave intensity detected by the radio wave intensity detection unit 31 is smaller than the second threshold ( Step S12). If the radio wave intensity is greater than or equal to the second threshold (step S12; NO), the process returns to step S11 and the subsequent processing is repeated.

  When the radio field intensity is larger than the first threshold (step S11; YES), the command processing unit 32 generates an unlock command and transmits the unlock command to the key opening / closing device 100 via the short-range communication unit 41. (Step S13). Thereafter, the process returns to step S11, and the subsequent processing is repeated. It is assumed that the authority information is transmitted together with this unlock command or prior to the transmission of the unlock command.

  When the unlocking command is received, the key opening / closing device 100 gives an operation instruction command to the thumb turn opening / closing mechanism 22 from the opening / closing control unit 13 of the control unit 10 if the portable terminal 200 that has transmitted the unlocking command has authority. The thumb turn 400 is operated to the “unlocked” state.

  On the other hand, when the radio field intensity is smaller than the second threshold (step S12; YES), the command processing unit 32 generates a locking command and sends the locking command to the key opening / closing device 100 via the short-range communication unit 41. Transmit (step S14). Thereafter, the process returns to step S11, and the subsequent processing is repeated. It is assumed that the authority information is transmitted together with the locking command as described above or prior to transmission of the locking command.

  The key opening / closing device 100 that has received the locking command gives an operation instruction command to the thumb-turn opening / closing mechanism 22 from the opening / closing control unit 13 of the control unit 10 if the portable terminal 200 that has transmitted the locking command has authority. 400 is activated to the “locked” state.

  As described above, when a predetermined time has passed without the locking command being given from the portable terminal 200 after the unlocking command is executed, the key opening / closing device 100 automatically performs the thumb turn regardless of the presence / absence of the command. 400 is activated to the “locked” state. This is because, for example, when the mobile terminal 200 suddenly moves away from the key opening / closing device 100, the key opening / closing device 100 cannot receive the locking command from the mobile terminal 200, and the thumb turn 400 is not returned to the “locked” state. This is to prevent the following from continuing.

  According to the above embodiment, it becomes possible to automatically operate the thumb turn of the key installed on the door in cooperation with the portable terminal.

  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 door key (thumb) is exemplified as the object that is automatically operated according to the distance between the mobile terminal 200, but the scope of the present invention is limited to this. It is not something. In addition, the present invention is not limited to an object with a physical operation part such as a thumb turn, but also includes an object with only an electric operation part. Specifically, for example, lighting devices can be turned on and off, television devices can be controlled (for example, power on / off switching, etc.), air conditioner power on / off switching, fire prevention / crime prevention system operation control, curtain automatic opening / closing control, etc. Application examples are possible.
