A sensor 33 (in FIG. 2, a reed switch that operates by detecting the magnetic force of a magnet embedded in the wall 4w of the house 4 is used) is provided.

  The controller CPU 31 can recognize the open / closed state (open state and closed state) of the front door 4a via the door open / close detection sensor 33. Then, the CPU 31 generates an open state signal when the entrance door 4a is in an open state (when the door open / close detection sensor 33 is in an on state), and when the entrance door 4a is in a closed state (door open / close detection). When the sensor 33 is off), a closed state signal is generated. The transponder activation signal is output from the controller CPU 31 to the transmission / reception circuit 41 on condition that the front door 4a is closed. The closed state of the front door 4a includes both the locked state and the unlocked state.

  The activation radio wave is transmitted by the transmission / reception circuit 41 to a predetermined transmission area centered on the outdoor antenna unit 40 on the outdoor side of the entrance door 4a. That is, when each electronic key 2 is held over the outdoor antenna unit 40 by the user and the electronic key 2 enters the transmission area, the electronic key 2 receives the activation radio wave and receives the activation radio wave. Using the electric power generated in the transponder 21 by the action of electromagnetic force, an ID code signal including its own ID code is modulated into a radio wave of a predetermined frequency (here, LF band), and the outdoor antenna unit is transmitted via the transponder 21. The data is transmitted to 40 transmission / reception circuits 41.

  When receiving the ID code signal via the transmission / reception antenna 42, the transmission / reception circuit 41 demodulates the ID code signal to generate a reception signal corresponding to the ID code signal, and outputs the reception signal to the controller CPU 31.

  Then, the controller CPU 31 determines whether or not the ID code included in the received signal matches one of the ID codes A to E stored in the EEPROM 32 (hereinafter, “ ID authentication "). When the ID authentication is established by matching both ID codes, the controller CPU 31 indicates that one of the authorized electronic keys 2a to 2e is used for locking / unlocking the entrance door 4a.

Functions as a means.

  When the unlock command signal is input, the motor driver 34 drives the electric thumb turn 35 to the unlock side. When the lock command signal is input, the motor driver 34 drives the electric thumb turn 35 to the lock side.

  When the unlocking state detection switch of the electric thumb turn 35 is turned on, the controller CPU 31 receives an unlocking state signal from the unlocking state detection switch and unlocks the front door 4a. Recognize that As a result, the controller CPU 31 recognizes that the unlocking of the entrance door 4a has been completed, and displays that effect on the display unit 43 of the outdoor antenna unit 40, and the entrance door 4a has shifted from the locked state to the unlocked state. The room control panel 50 is notified of the fact and the management number (any one of 1 to 5) of the regular electronic keys 2a to 2e used for unlocking.

  On the other hand, when the lock state detection switch of the electric thumb turn 35 is turned on, the controller CPU 31 recognizes that the entrance door 4a is locked by receiving a lock state signal from the lock state detection switch. To do. As a result, the controller CPU 31 recognizes that the locking of the entrance door 4a has been completed, displays that effect on the display unit 43 of the outdoor antenna unit 40, and also indicates that the entrance door 4a has shifted from the unlocked state to the locked state. And the management number (any one of 1-5) of the regular electronic keys 2a-2e used for locking is notified to the indoor operation panel 50.

  In this embodiment, referring to FIG. 1 and FIG. 2, when the front door 4 a is unlocked and closed, any one of the electronic keys 2 a to 2 e registered in the EEPROM 32 is connected to the outdoor antenna unit 40. Then, the controller CPU 31 performs the ID authentication, and locks the entrance door 4a via the electric thumb turn 35 on the condition that the ID authentication is established. Then, when one of the electronic keys 2a to 2e is held over the outdoor antenna unit 40 again within a predetermined time (for example, within 5 seconds), the controller CPU 31 performs the ID authentication again, and the ID authentication is established. As a condition, the door locking / unlocking control device 3 is configured to be set in the “warning mode”.

  As shown in FIG. 2, the controller 30 is provided with an audio circuit 37 that converts an electrical signal into an audio signal. The controller CPU 31 converts the audio signal into the audio signal via the audio circuit 37. The speaker 37a which emits a sound based on this is electrically connected. In the present embodiment, the audio circuit 37 and the speaker 37a function as an alarm generating unit that issues an alarm to the surroundings when the door locking / unlocking control device 3 is set to the “warning mode”.

  Further, the controller CPU 31 confirms that the entrance door 4a is unlocked and opened by an unauthorized act when the entrance door 4a is opened and unlocked without the establishment of the ID authentication. Configured to recognize.

  That is, the controller CPU 31 receives the unlock state signal from the electric thumb turn 35 even though the ID authentication for unlocking and opening the front door 4a has not been established within a predetermined time (for example, within 10 minutes). And when the opening state signal is generated based on the detection result of the opening / closing state of the entrance door 4a by the door opening / closing detection sensor 33, it is recognized that the entrance door 4a has been unlocked and opened by an unauthorized act. Is configured to do.

  When the door locking / unlocking control device 3 is set to the “warning mode” and the controller CPU 31 recognizes the unlocking and opening of the front door 4a due to the fraudulent act, Then, based on an audio signal output from the controller CPU 31, an alarm is sounded around the audio circuit 37 and the speaker 37a for a predetermined time (for example, 1 minute).

  Further, the controller CPU 31 stores the ID code of the electronic key 2 in the EEPROM 32 no matter how the registration switch 36 is operated when the door locking / unlocking control device 3 is set to the “warning mode”. It is configured to prohibit the setting to “registration mode”.

  When the door locking / unlocking control device 3 is set to the “warning mode”, the controller CPU 31 holds any one of the electronic keys 2a to 2e registered in the EEPROM 32 over the outdoor antenna unit 40. The ID authentication is performed, and the setting of the “warning mode” is canceled on the condition that the ID authentication is established.

  As shown in FIG. 1, in the present embodiment, the indoor operation panel 50 is provided with an indoor operation panel CPU 51 connected to the controller CPU 31 so as to be able to communicate with each other by serial communication. The controller CPU 31 outputs an unlocking / unlocking state signal (locking state signal, unlocking state signal) to the indoor operation panel CPU 51 according to the unlocking / unlocking state of the entrance door 4a, and opens / closes the entrance door 4a. Depending on the state, an opening / closing state signal (open state signal, closed state signal) of the front door 4a is output.

  The indoor operation panel 50 is electrically connected to the CPU 51 for the indoor operation panel, and based on the locking / unlocking state signal of the entrance door 4a output from the CPU 31, the unlocking / unlocking state is displayed. A state notification LED 52 and an opening / closing state notification LED 53 for displaying the opening / closing state of the front door 4a based on the opening / closing state signal of the front door 4a output from the CPU 31 are provided. The unlocking state notification LED 52 is turned on when the entrance door 4a is unlocked, and is turned off when the entrance door 4a is unlocked. The open / close state notification LED 53 is connected to the entrance door 4a. It lights up when it is open, and turns off when it is closed.

  The indoor operation panel 50 is electrically connected to the indoor operation panel CPU 51 and displays (notifies) the management number (any one of 1 to 5) of the electronic key 2 used for the locking / unlocking operation 7 A segment LED 55 is provided. For example, when the electronic key 2 a is used for unlocking, the indoor operation panel CPU 51 displays the management number 1 of the electronic key 2 a on the 7-segment LED 55 based on the communication with the controller CPU 31. Similarly, when the electronic keys 2b to 2e are used, the management numbers 2 to 5 of the electronic keys 2b to 2e are displayed on the 7-segment LED 55, respectively. Thereby, the user can recognize one of the electronic keys 2a to 2e used for unlocking.

  In the indoor operation panel 50 shown in FIG. 1, a push switch (push button) 54 for manually locking the entrance door 4a is electrically connected to the indoor operation panel CPU 51. For example, after the user who is a resident of the house 4 completes unlocking the front door 4a using any of the regular electronic keys 2a to 2e, enters the room through the front door 4a, The entrance door 4a can be manually locked by operating the push switch 54 after confirming that the entrance door 4a is closed by the open / close state notification LED 53 of the indoor operation panel 50. Here, when the unlocking of the front door 4a is completed, the management number (any one of 1 to 5) of the authorized electronic key 2 used for unlocking is displayed on the 7-segment LED 55.

  When the push switch 54 is operated in this way, the CPU 51 for the controller notifies that fact to the CPU 31 for the controller, and when the entrance door 4a is locked, the CPU 31 unlocks the entrance door 4a. Therefore, while the unlocking command signal is output to the motor driver 34, when the front door 4a is unlocked, the unlocking command signal is output to the motor driver 34 to lock the front door 4a. . Here, when the entrance door 4 a is locked, the electric thumb turn 35 is driven to the unlocking side by the motor driver 34. On the other hand, when the front door 4a is unlocked in this way, the electric thumb turn 35 is driven to the locking side by the motor driver 34.

  When the locking of the entrance door 4a is completed, the lock state detection switch of the electric thumb turn 35 is turned on, and the controller CPU 31 confirms that the entrance door 4a is locked and that the locking is completed. It recognizes and displays that on the display part 43 of the outdoor antenna unit 40, and notifies the CPU 51 for indoor operation panel that it has shifted from the unlocked state to the locked state.

  Then, the indoor operation panel CPU 51 recognizes that the locking of the entrance door 4a is completed via the controller CPU 31, and turns off the locking / unlocking state notification LED 52 so that the entrance door 4a is locked. In addition, the display of the management number of the regular electronic key 2 by the 7-segment LED 55 is finished after a predetermined time.

  The door locking / unlocking control system 1 and the door locking / unlocking control device 3 according to the present embodiment are configured as described above. Hereinafter, with reference to FIGS. 1 to 3, a process for prohibiting the registration of the electronic key 2 when the door locking / unlocking control device 3 according to the present embodiment is set to the “warning mode” will be described. This process is executed by a predetermined control program stored in the memory 31a of the controller CPU 31 of the controller 30.

  First, in step S1 of FIG. 3, when the front door 4a is unlocked and closed, for example, when any of the electronic keys 2a to 2e registered in the EEPROM 32 is held over the outdoor antenna unit 40, the controller door The CPU 31 determines whether or not the ID code included in the received signal received from any of the electronic keys 2a to 2e matches any ID code of the ID codes A to E stored in the EEPROM 32. ID authentication is performed, and the entrance door 4a is locked via the electric thumb turn 35 on condition that the ID authentication is established. Then, when the electronic key 2 is again held over the outdoor antenna unit 40 within a predetermined time (for example, within 5 seconds), the controller CPU 31 performs the ID authentication again, on the condition that the ID authentication is established. The door locking / unlocking control device 3 is set to the “warning mode” (step S1). In this “alert mode”, the controller CPU 31 unlocks and opens the entrance door 4a by an illegal act such as the entrance door 4a being unlocked with a mechanical key or the electric thumb turn 35 being illegally turned. When this is recognized, a predetermined audio signal is output to the audio circuit 37, and an alarm is sounded from the speaker 37a for a predetermined time (for example, 1 minute).

  Next, in step S2, the controller CPU 31 determines whether or not the “warning mode” has been canceled by the user in the “warning mode” (step S2). That is, when the door locking / unlocking control device 3 is set to the “warning mode”, when any of the electronic keys 2a to 2e registered in the EEPROM 32 is held over the outdoor antenna unit 40, the controller CPU 31 ID authentication is performed, and on the condition that the ID authentication is established, the setting of the “warning mode” is canceled (in the case of YES), and the process proceeds to step S3 to step S7. On the other hand, if the ID authentication is not established, the controller CPU 31 continues to set the “warning mode” (in the case of NO), and proceeds to step S3a to step S4a.

In step S3 to step S7, since the “warning mode” has already been canceled, the electronic key 2 can be registered.
That is, in step S3, the entrance door 4a is unlocked and opened, and the registration switch 36 provided on the side surface of the entrance door 4a is pressed long (for example, 2 seconds or more) (step S3).

  Then, in step S4, the controller CPU 31 sets the door locking / unlocking control device 3 to the “registration mode” for registering the ID code of the electronic key 2 in the EEPROM 32 (step S4).

  In subsequent step S5, the electronic key 2 to be registered is held over the transmission area of the outdoor antenna unit 40 (step S5). Thus, the ID code of the electronic key 2 is transmitted as an ID code signal by radio waves in the LF band, wirelessly transmitted to the transmission / reception circuit 41 of the outdoor antenna unit 40, and transmitted to the controller CPU 31. At this stage, the ID code transmitted to the CPU 31 is temporarily held in the controller CPU 31 and the storage (registration) in the EEPROM 32 has not been finalized.

  In step S6, the registration switch 36 is pressed for a short time (for example, about 1 second) (step S6). Then, the registration of the ID code of the electronic key 2 temporarily held in the step controller CPU 31 is confirmed in the EEPROM 32 (step S7).

On the other hand, in step S3a and step S4a, the “warning mode” is continued without being cancelled, so the electronic key 2 cannot be registered.
That is, in step S3a, the entrance door 4a is unlocked and opened, and the registration switch 36 provided on the side surface of the entrance door 4a is pressed long (for example, 2 seconds or more) (step S3a).

  However, since the “alert mode” is set in step S3a, the controller CPU 31 sets the “registration mode” in which the door lock / unlock control device 3 registers the ID code of the electronic key 2 in the EEPROM 32. Setting is prohibited. Therefore, in step S4a, the “registration mode” is not set, and the “registration mode” is not set (step S4a). That is, the electronic key 2 is registered unless the setting of the “warning mode” is canceled by using any one of the electronic keys 2 a to 2 e registered in the EEPROM 32 or the EEPROM 32 and the controller CPU 31, that is, the controller 30 are replaced. It becomes impossible to perform.

According to the door locking / unlocking control device 3 and the door locking / unlocking control system 1 of the present embodiment, the following operations and effects can be obtained.
(1) Once the door locking / unlocking control device 3 is set to the “warning mode”, the registration of the electronic key 2 is prohibited unless the setting of the “warning mode” is canceled. Unauthorized registration of the key 2 and unauthorized locking / unlocking operation of the front door 4a are easily and reliably prevented, and the security of the house 4 is effectively ensured.

  (2) The fact that ID authentication (ID code collation) via wireless communication is established between the electronic keys 2a to 2e registered in the EEPROM 32 and the controller CPU 31 is an indispensable condition for canceling the “warning mode” setting. Therefore, if all of the registered electronic keys 2a to 2e are lost, the “warning mode” setting cannot be canceled unless the EEPROM 32 and the controller CPU 31 are replaced. It becomes possible to ban.

  (3) An ID included in a received signal transmitted and received from any one of the electronic keys 2a to 2e when wireless communication is performed between the electronic keys 2a to 2e registered in the EEPROM 32 and the controller CPU 31. On the condition that ID authentication for determining whether or not the code matches one of the ID codes A to E stored in the EEPROM 32 has been established, the “warning mode” is set and the setting is canceled. Done. In other words, unless such ID authentication is established, the “warning mode” setting and the cancellation of the setting are not performed. For this reason, by setting the ID authentication between the registered electronic keys 2a to 2e and the controller CPU 31, it is possible to easily set and cancel the “warning mode”. If all the electronic keys 2a to 2e are lost, the “warning mode” setting cannot be canceled unless the EEPROM 32 and the controller CPU 31 are replaced. And since registration of the electronic key 2 is completely prohibited by this, thorough prevention of unauthorized registration of the electronic key 2 by a third party and unauthorized locking / unlocking operation of the front door 4a is ensured, and the security of the house 4 is improved. It is ensured more effectively.

  (4) After the door locking / unlocking control device 3 is once set to the “warning mode”, when the “warning mode” is canceled by using the electronic keys 2a to 2e registered in the EEPROM 32, the entrance The electronic key 2 is registered on the condition that the registration switch 36 provided on the door 4a is operated and set to the “registration mode”. Therefore, the electronic key 2 can be re-registered without replacing the EEPROM 32 and the controller CPU 31 while ensuring the security of the house 4.

  (5) Unless the “alert mode” setting of the door locking / unlocking control device 3 is canceled, registration of the electronic key 2 is prohibited, unauthorized registration of the electronic key 2 by a third party, and unauthorized unlocking of the front door 4a The door locking / unlocking control system 1 is obtained in which the locking operation is easily and reliably prevented and the security of the house 4 is effectively secured.

The above embodiment may be modified as follows.
In the above embodiment, in the “alert mode”, the controller CPU 31 detects that the entrance door 4a has been opened by the door opening / closing detection sensor 33 without passing through ID authentication for opening the entrance door 4a. The audio circuit 37 and the speaker 37a are configured to generate an alarm when the alarm occurs. However, the present invention is not limited to this, and in the “warning mode”, when the controller CPU 31 detects that the front door 4a is unlocked without the establishment of the ID authentication, the sound circuit 37 and the speaker 37a warn. It can also be configured to occur.

  In the above embodiment, when the front door 4a is unlocked and closed, when any of the electronic keys 2a to 2e registered in the EEPROM 32 is held over the outdoor antenna unit 40, the controller CPU 31 ID authentication for determining whether the ID code included in the received signal transmitted from any of 2a to 2e matches the ID code of any of the ID codes A to E stored in the EEPROM 32 I do. Then, on the condition that the same ID authentication is established, the entrance door 4a is locked via the electric thumb turn 35. Then, when any one of the electronic keys 2a to 2e is again held over the outdoor antenna unit 40 within a predetermined time, the controller CPU 31 performs the ID authentication again, on the condition that the ID authentication is established. The lock control device 3 is configured to be set in the “warning mode”. However, the operation for setting the “warning mode” is not limited to this. For example, the door is placed on any one of the electronic keys 2 a to 2 e registered in the EEPROM 32 over the outdoor antenna unit 40, and the ID authentication is established. It is also possible to set the locking / unlocking control device 3 to the “warning mode”.

  In the above embodiment, even if the door locking / unlocking control device 3 is once set to the “warning mode”, when the setting of the “warning mode” is canceled, the ID code of the electronic key 2 is transferred to the EEPROM 32. Can be set to "Registration mode". However, the present invention is not limited to this. Once the door locking / unlocking control device 3 is set to the “warning mode”, it is prohibited to set the “registration mode” again even if the “warning mode” is canceled. It can also be configured. According to this configuration, any one of the registered electronic keys 2a to 2e can be prepared, and even if the "warning mode" is canceled, the "warning mode" setting is canceled unless the EEPROM 32 and the controller CPU 31 are replaced. The registration of the electronic key 2 is completely prohibited. As a result, the unauthorized registration of the electronic key 2 by a third party and the prevention of unauthorized locking / unlocking operation of the front door 4a are further thorough, and the security of the house 4 is enhanced as much as possible.

  In the above embodiment, the controller CPU 31 recognizes when the door locking / unlocking control device 3 recognizes the unlocking and opening of the front door 4a due to fraud in the case where the door locking / unlocking control device 3 is set to the “warning mode”. From this point, an alarm is sounded around the sound circuit 37 and the speaker 37a for a predetermined time. However, the present invention is not limited to this, and while the door locking / unlocking control device 3 is set to the “warning mode”, the alarm is continuously blown around the door unless the setting of the “warning mode” is canceled. You can also Further, in the door locking / unlocking control device 3, for example, the alarm sounding time can be arbitrarily adjusted by operating the registration switch 36 or the like, and furthermore, only while the alarm is sounding. The door locking / unlocking control device 3 can be configured to be prohibited from being set to the “registration mode”.

Further, technical ideas that can be grasped from the above-described embodiments and modifications will be described below.
○ In door locking and unlocking control device, once set in the warning mode, then even if the same warning mode is canceled, the registration of the electronic key has to be prohibited.

  According to this configuration, even if the “warning mode” is canceled, the setting of the “warning mode” cannot be canceled unless the ID code storage means and the door locking / unlocking control means are replaced, and electronic key registration is completely prohibited. The As a result, the unauthorized registration of the electronic key by a third party and the prevention of unauthorized locking / unlocking operation of the door are further thorough, and the security of the object is enhanced as much as possible.
