As a control device for a lock device capable of authentication registration of a portable device in the authentication unit, a device described in Patent Document 1 is known. In this conventional example, the control device is provided with a registration switch, and the control device can be shifted to the authentication registration mode of the portable device by operating the registration switch.
JP 2001-262883 A

  However, in the above-described conventional example, since the control device immediately shifts to the authentication registration mode by operating the registration switch, it is necessary to arrange the control device indoors to prevent unauthorized registration and the like. As a result, for example, it becomes impossible to configure the control device integrally and fix it to the outdoor wall surface of the existing door, which reduces the flexibility of the device configuration and allows communication with a portable device. When it is necessary to arrange the transmission / reception unit on the outdoor side due to distance restrictions, there is a disadvantage that processing to the door is required.

  The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a control device for a locking device that increases the flexibility of the device configuration by arranging members required for registration operation on the outdoor side. And

According to the present invention, the object is
A control unit 3 that starts communication with the portable device 2 by turning on the authentication start switch 1 disposed on the outdoor side, and operates the locking device to unlock / lock on the condition that the authentication with respect to the portable device 2 is established;
A control device for a locking device having an authentication ID storage unit 4 into which an authentication ID for the portable device 2 is written when the control unit 3 is in a registration mode;
A cylinder lock rotation detection unit 27 for notifying the control unit 3 of the rotation operation of the emergency cylinder lock 12 for assuring the unlocking operation of the lock device by a mechanical key at the time of failure,
The control unit 3 receives a notification from the cylinder lock rotation detection unit 27 and also receives a notification from the request switch detection circuit 19 for notifying that the authentication start switch 1 is turned on, and a registration mode for the registration portable device 2. Transition to
In the authentication ID storage unit 4, an authentication ID for the registration portable device 2 is written by the control unit 3 communicating with the registration portable device 2 in the registration mode for the registration portable device 2.
And the said control part 3 is achieved by providing the control apparatus of the lock apparatus which transfers to the registration mode about portable apparatuses 2 other than the registration portable apparatus 2 by the authentication establishment with respect to the registration portable apparatus 2. FIG.

  The control device is configured to supply power to the control unit 3 only when the authentication start switch 1 such as a push button is turned on in order to reduce power consumption and enable battery driving. When activated, the control unit 3 communicates with the portable device 2 possessed by the user and reads the ID information set in the portable device 2 and compares it with the authentication ID in the ID storage unit. When the coincidence with the authentication ID is confirmed (authentication is established), the actuator 5 is driven to lock and unlock the locking device.

As described above, in addition to the normal operation mode in which the control unit 3 communicates with the portable device 2 to control the driving of the actuator 5, the unregistered portable device 2 is newly written in the ID storage unit as an authentication target. Has a registration mode. The transition to the registration mode is performed when an unregistered portable device 2 communicates with an authentication unit configured in the control unit 3 after authentication by a registration portable device 2 different from the portable device 2 is established. The mobile device 2 is registered as the authentication target mobile device 2.

  Therefore, in the present invention, when the mode is changed to the registration mode, in order to use the authentication start switch 1 arranged outside the room for starting the apparatus, the arrangement of the parts inside the room is avoided completely or as much as possible. it can. As a result, the degree of freedom of device configuration increases. Moreover, since the transition to the registration mode is conditional on the establishment of authentication, unauthorized registration can be completely prevented.

  The portable device 2 can be operated with one type and a plurality of types, but if two types of normal operation devices and provisional operation devices are prepared, for example, the contractor-specific portable device 2 under construction and maintenance of the provisional operation device It can be used until the operation by the normal operation machine is started.

  In order to control so that only one of the two types of authentication ID is used as the authentication ID, for example, when the construction or the like is completed and the operation by the normal operation unit is started, the control unit 3 Unlocking with a temporary operation machine is definitely prohibited. In addition, registration of a provisional operation machine due to construction or the like can be performed on condition that the registration of the normal operation machine that has been used in the past has been deleted. If it is registered as, unlocking with a normal operation machine that has been used in the past is certainly impossible, so that locking management in a rental house or the like becomes easy and reliable.

  Furthermore, since the provisional operation machine and the normal operation machine can be re-registered any number of times regardless of whether or not the portable device 2 is the same, the flexibility of operation is improved.

  According to the present invention, since the members required for the registration operation can be arranged on the outdoor side, it is possible to arrange all or most of the components on the outdoor side, and increase the flexibility of the apparatus configuration. be able to.

  1 and 2 show an embodiment of the present invention in which a control device for a lock device and a motor (actuator 5) are housed in a housing and configured as an electric lock A. FIG. In this embodiment, the electric lock A is used by being fixed to the outdoor wall surface of the door body 6, and a shaft 5 a is connected to the actuator 5, and the lock box is fixed inside the door body 6. 7 is connected.

  The lock box 7 is provided with a dead bolt 7a and a latch 7b. The shaft 5a is rotationally driven by the actuator 5, or the indoor thumb-turn device 8 is rotated and unlocked. Further, a handle 9 or a knob is connected to the lock box 7, and the latch 7b is operated by operating these.

  In the housing, as will be described later, a request switch (authentication start switch 1) for starting the control unit 3 is disposed at a position where it can be operated from the outside of the housing, and a display panel 10 is disposed around the request switch. As shown in FIG. 2 (b), the display panel 10 is provided with pictograms 10a indicating unlocking, locking, and running out of battery, and LEDs 11 for displaying corresponding states.

The housing also houses an emergency cylinder lock 12, a battery case 13, and a transmission / reception circuit 14 (see FIG. 3) for assuring a door opening operation with a mechanical key in the event of a failure. The transmission / reception circuit 14 is configured as an RFID reader capable of communicating with the portable device 2 configured as an RFID (Radio Frequency Identification) card together with the connected antenna 14a. The battery case 13 accommodates a battery 15 for supplying power to the control unit 3, the actuator 5, and the cover unlocking actuator 5, and a cover 17 locked by the cover locking unit 16 to prevent mischief such as removal of the battery 15. It is blocked by. The cover locking portion 16 is configured by locking a plunger 18a of a cover unlocking actuator 18 made of a pull type solenoid to which a restoring force is applied in the push direction to a locking portion 17a of the cover 17. When the cover unlocking actuator 18 is pulled, the cover 17 is unlocked, the cover 17 is removed, and the battery 15 can be replaced.

  The illustrated electric lock A is configured to operate a lock box 7 fixed in the door body 6; however, the dead bolt 7a and the latch 7b are built in the housing, or the actuator 5 is installed. It can also be modified to be placed in the lock box 7.

  The control device B will be described based on the functional block diagram shown in FIG. 3 and the operation flow in the normal use mode shown in FIG. The control device B is configured to activate various driver circuits by a CPU (control unit 3) that operates in accordance with a program stored in a ROM (not shown) to perform predetermined operations. Control by the CPU 3, that is, the control device B First, the operation is started by turning on the request switch 1 (step S100). The depression of the request switch 1 is detected by the request switch detection circuit 19 and notified to the CPU 3, and the CPU 3 receiving the notification inquires the battery voltage from the voltage detection circuit 20 (step S101). When the detection voltage in the voltage detection circuit 20 is lower than the predetermined value, the CPU 3 drives the buzzer output circuit 21 to sound a warning buzzer sound from the buzzer 23 and drives the LED output circuit 22 to notify the battery exhaustion. LED 11 is blinked (step S102).

  On the other hand, when the detection voltage in the voltage detection circuit 20 is a predetermined value, after the buzzer sound for notifying the receipt of the operation is sounded (step S103), the locking / unlocking state of the lock box 7 is controlled by the locking / unlocking control circuit 24. Is detected (step S104), and the LED 11 is selected and blinked according to the locking / unlocking state (step S105).

  Thereafter, the CPU 3 transmits a request signal from the transmission / reception circuit 14 to the portable device 2 side and waits for a response from the portable device 2 side (step S106). After pressing the request switch 1, when the user does not hold the portable device 2 in the vicinity of the antenna 14a, or by holding the portable device 2 of a different type, the transmission / reception circuit 14 does not receive a response from the portable device 2. In this case, the CPU 3 drives the timer circuit 25 and monitors whether or not the state of the lock box 7 is changed by the thumb turn device 8 (step S107). When the locking / unlocking operation by the thumb turn device 8 has not been performed for a predetermined time (in this embodiment, 5 seconds) (step S108), the CPU 3 ends the control and returns to the initial state, that is, the inactive state.

  On the other hand, when the transmission / reception circuit 14 receives the response signal from the portable device 2, after the LED 11 is turned off once (step S109), it is determined whether or not the above-described authentication operation by the user is based on a registration card described later. Determination is made by comparing the ID information transmitted from the portable device 2 with the authentication ID in the authentication ID storage unit 4 (step S110). As a result of the determination, if the portable device 2 is a registration card, the CPU 3 sets a flag indicating that the access was made by the registration card (step S111) and uses it to determine the transition to the registration mode described later. If it is determined in step S110 that the card is not a registration card, it is determined whether the portable device 2 used for authentication has the authentication ID set in the user card (normal operation device) (step S112). If the authentication is not established, the buzzer 23 is sounded (step S113), and the control is terminated.

  On the other hand, when authentication is established in step S112, the lock / unlock control circuit 24 is again inquired about the lock / unlock state of the lock box 7 (step S114). The actuator 5 is driven to rotate the locking direction in the locking direction to shift the lock box 7 to the locking state (step S115), and when it is in the locking state, the actuator 5 is driven to the unlocked state side (step S116). Thereafter, the buzzer 23 is blown by the blowing method corresponding to the locking / unlocking operation (step S117), and the LED 11 of the color corresponding to the locking / unlocking operation is turned on (step S118).

  When the locking / unlocking operation is completed as described above, the CPU 3 inquires the battery voltage again from the voltage detection circuit 20 (step S119). When the detected voltage in the voltage detection circuit 20 is lower than the predetermined value, the CPU 3 displays the buzzer output circuit. 21 is driven to sound a warning buzzer sound from the buzzer 23 (step S120). If step S120 is executed, or if battery exhaustion is not detected in step S119, the flag set in step S111 is confirmed (step S121). If the flag is set, the process shifts to the registration mode monitoring state. (Step S122).

  On the other hand, when the unlocked state is detected in step S114 and the registration card flag is not set in step S121, the control is terminated and the power supply from the battery 15 is stopped. On the other hand, when the locked state is detected in step S114 and the registration card flag is not set in step S121, the process shifts to the battery replacement monitoring state (step S123).

  FIG. 5 shows a procedure for removing the cover 17 of the battery case 13 from the battery replacement monitoring state (step S123). As described above, the cover 17 of the battery case 13 is locked by the cover locking unit 16, and when the CPU 3 enters the battery replacement monitoring state (step S123), in order to confirm the transition to the case unlocking mode, First, the timer circuit 25 is activated (step S201), and the output of the request switch detection circuit 19 is monitored (step S202). If the user does not press down the request switch 1 within the time set in the timer circuit 25 (2 seconds in this embodiment) (step S203), the CPU 3 ends the control and returns to the initial state.

  On the other hand, when the pressing of the request switch 1 is detected within the timer setting time, the timer circuit 25 is activated again (step S204), and the output of the request switch detection circuit 19 is monitored. In this state, when the request switch 1 is kept pressed for the timer set time (3 seconds in this embodiment) (steps S205 and S206), the CPU 3 activates the buzzer output circuit 21 and sounds the buzzer 23 (step S207). ), Transition to case unlocking mode. In the case unlocking mode, the CPU 3 drives the cover unlocking actuator control circuit 26 to pull-drive the cover unlocking actuator 18 to unlock the cover locking part 16 (step S208). Next, in order to limit the unlocking time of the cover locking unit 16, a waiting time process is performed for a predetermined time (3 seconds in this embodiment) (step S209), and then power is supplied to the cover unlocking actuator 18. The cover is locked and the cover locking part 16 is returned to the locked state (step S210), and the control is terminated.

  The user can remove the cover 17 and replace the battery 15 when the cover locking portion 16 is unlocked. Since the cover locking portion 16 can move the plunger 18a of the cover unlocking actuator 18 in the pull direction against the return force in the push direction even in the locked state, the cover 17 is pushed in after the replacement. It can be installed in a locked state.

  Furthermore, in this embodiment, in addition to the portable device 2 (user card: normal operation device) used by the user, the control device B includes a construction portable device 2 (construction card: provisional operation device) and a registration device. The mobile device 2 (registration card) is used.

  In this embodiment, the registration card is the user card and the portable device 2 to which the authorization for registering the authentication ID of the construction card and the authority for deleting the registration are given. The registration ID of the registration card itself is the special ID shown in FIG. It is registered in the procedure of. That is, first, when registering a registration card, the emergency cylinder lock 12 is rotated by 90 ° (step S301). The rotation operation of the emergency cylinder lock 12 is notified to the CPU 3 via the cylinder lock rotation detection unit 27, and the CPU 3 starts monitoring the output change of the request switch detection circuit 19.

  When the request switch 1 is pressed in this state (step S302), the CPU 3 activates the timer circuit 25 and measures the pressing time of the request switch 1 (step S303). If the pressing state is not continued for a predetermined time (3 seconds in this embodiment), it is checked whether or not the cylinder lock rotation detection unit 27 has detected a rotation operation to the emergency cylinder lock 12 (step S304). When the emergency cylinder lock 12 is returned to the initial position, the registration card registration mode ends.

  On the other hand, when the continuous pressing of the request switch 1 is detected in step S303, the mode shifts to the registration card registration mode. First, in order to notify the user of the status transition, the buzzer 23 is sounded and the LED 11 is blinked ( In step S305, the transmission / reception circuit 14 is monitored (step S306). If the user holds the registration card over the antenna within a predetermined time (5 seconds in this embodiment) from step S305, the CPU 3 confirms that the held card is not a construction card (step S307), and as a registration card Register (step S308).

  When the registration of the registration card is completed, the buzzer 23 is sounded and the LED 11 is turned on to notify the user of the completion of registration (step S309), and the request switch 1 is waited for operation (step S302).

  On the other hand, if it is detected in step S307 that the card is a construction card, the buzzer 23 is blown to notify the user of the card difference (step S310), and then the card reading waiting state (step S306) is restored. After a predetermined time has elapsed (step S311), the request switch 1 is returned to the operation waiting state (step S302).

  The construction card is mainly intended to be used by construction and maintenance companies, and if it can be authenticated, the locking and unlocking operation of the normal lock box 7 in the above-described step S100 series, and the step, as with the user card, The battery replacement mode in the S200 range can be executed. In this embodiment, when one of the user card and the construction card can be authenticated, the other is in an exclusive relationship in which the other is in an unauthenticated state, so the user card is delivered to the resident Therefore, the unlocking operation of the contractor who went in and out during the construction is prohibited without collecting the construction card.

  7 and 8 show the procedure for registering the construction card and the user card. The registration of the construction card and the user card is executed after the transition to the registration mode. As described above, the transition from the registration mode monitoring state (step S122) is performed, and the CPU 3 causes the buzzer 23 to sound and the LED 11 to blink. (Step S402) to notify the user of the state transition.

  Thereafter, the card reading is confirmed (step S403). When the card is not confirmed, that is, when the request switch 1 is depressed again without holding the card (portable device 2) over the antenna 14a (step S404), the user Transition to card erase mode. In order to make the transition to the erasing mode clear, the pressing of the request switch 1 may be controlled in the same manner as the procedure for removing the cover 17 of the battery case 13 (S204 to S206). On the other hand, if the request switch 1 is not pressed even after a predetermined time (5 seconds in this embodiment) has elapsed (step S405), the buzzer 23 stops ringing and the LED 11 is also turned off (step S405). S406) The control is terminated.

  On the other hand, when transitioning to the user card erasing mode, first, the buzzer 23 is sounded (step S407) to notify the user of the mode transition. For example, the user card can be deleted without preparing the user card in order to eliminate the collection of the user card when the rental house is delivered, etc., and the registration card is held over following step S407. (Step S408), all the data of the user card authentication ID in the authentication ID storage unit 4 is deleted (Step S409), and thereafter, the user card cannot be authenticated. If the authentication ID data is successfully erased, the buzzer 23 sounds and the LED 11 blinks (step S410), and the control ends.

  On the other hand, if the CPU 3 does not receive a registration card detection signal in step S407, it detects that the request switch 1 has been pressed (step S411), and if it has not detected even after a predetermined time (5 seconds) has elapsed. (Step S412), the control is terminated, and when the pressing of the request switch 1 is detected, the control is immediately terminated.

  If a card is detected in step S403, the card is a user card, but whether it is a construction card is identified based on the ID information (step S421). It is checked based on the number registered in the authentication ID storage unit 4 whether or not the number of sheets that can be registered (20 in this embodiment) has been reached (step S422). If the number of user cards to be registered exceeds the maximum number that can be registered, the buzzer 23 sounds and the LED 11 blinks to notify the user that registration is impossible (step S423), and then returns to the registration mode monitoring state (step S122). To do.

  On the other hand, if the number of user cards is equal to or less than the possible number, it is identified whether or not the held user card is a registered card (step S424). If registered, the buzzer 23 sounds and the LED 11 blinks. To notify the user of a duplication warning (step S425), and then return to the registration mode monitoring state (step S122). If not registered, the user card is additionally registered (step S426) and stored in the authentication ID storage unit 4.

  The registration of the user card is also the end of the operation by the construction card. After that, the CPU 3 sets the construction mode flag after executing step S426 so that the ID information of the construction card is not used as authentication information. After clearing (step S427) and then issuing an operation completion signal (step S428), the process returns to the registration mode monitoring state (step S122).

  On the other hand, if a construction card is detected in step S421, it is detected from the authentication ID storage unit 4 whether or not the user card has been completely erased (step S431). After sounding (step S432), the process returns to the registration mode monitoring state (step S122).

  If the user card has been erased, the construction card ID information is stored as an authentication ID in the authentication ID storage unit 4 (step S433), and a completion signal is notified (step S434). Since the authentication ID can be overwritten, it is possible to use a different construction card as many times as necessary. After the ID registration, the construction mode flag is set in order to be operated by the construction card (step). S435), the process jumps to the control end preparation step (step S406).
