  According to this configuration, when the operation of the door lock is performed in the first door, an operation signal for notifying the second door of the operation is output from the first door to the second door through the communication line. When an operation signal is input at the second door, the door lock of the second door is operated based on the operation signal. That is, the operation of the door lock of the second door is interlocked with the operation of the door lock of the first door. Therefore, it becomes difficult to forget to operate the door lock.

  In the door lock control system, the operation at the first door is preferably an operation for locking the door lock from the outside. According to this configuration, when the door lock of the first door is locked from the outside, it becomes difficult to forget to lock the other doors.

  The door lock control system includes a confirmation processing unit that confirms to the user whether or not the second door may perform the same operation when the door lock is operated on the first door. The information output unit preferably outputs the operation signal to the second door when it is confirmed that the door lock may be operated in the confirmation processing unit. According to this configuration, when the door lock of the second door is interlocked with the operation of the door lock of the first door, it is confirmed to the user whether or not the door lock of the second door may be interlocked. Therefore, when it is not desired to interlock the door lock of the second door with the operation of the door lock of the first door, it is possible to cope with this.

  In the door lock control system, the information output unit is provided not only for the operation of the door lock wirelessly via the electronic key, but also for a mechanical key that switches the door lock by a mechanical operation, or the door. Even when the door lock is operated by a thumb turn, it is preferable that the operation signal is output to the second door, and the operation of the door lock of the second door is interlocked with the door lock of the first door. . According to this configuration, even when the door lock is operated with a mechanical key or thumb turn on the first door, the door lock of the second door can be interlocked. This is even more advantageous. Moreover, it is advantageous for ensuring the convenience of the locking / unlocking operation.

  In the door lock control system, when the operation of the door lock is performed on the second door by providing the information output unit on the second door and providing the operation execution unit on the first door, It is preferable that the door lock of the first door is interlocked with the door lock of the second door. According to this configuration, when the door lock of the second door is operated, the door lock of the first door is interlocked with this, which is further advantageous for preventing the user from forgetting to operate the door lock. Moreover, it is advantageous for ensuring the convenience of the locking / unlocking operation.

  According to the present invention, in the door lock control system, it is possible to make it difficult to forget to operate the door lock.

  In the communication of the key operation free system, for example, LF (Low Frequency) band radio waves are used for building 1 → electronic key 4 communication, and UHF (Ultra High Frequency) band radio waves are used for electronic key 4 → building 1 communication. Is done. The key-free operation is, for example, an operation in which the operation of the door lock 3 is permitted or executed if smart verification is established without actually operating the electronic key 4. In the case of this example, the operation of the door lock operation unit 6 provided in the door 2 is a trigger, and the locking / unlocking of the door lock 3 is switched. The door lock operation unit 6 may be a push switch, for example.

  The electronic key 4 includes a key control unit 7 that controls the operation of the electronic key 4, a reception antenna 8 that receives radio waves in the electronic key 4, and a transmission antenna 9 that transmits radio waves in the electronic key 4. An electronic key ID which is a unique ID of the electronic key 4 is written and stored in the memory 10 of the key control unit 7. The receiving antenna 8 receives, for example, LF radio waves. The transmission antenna 9 transmits, for example, UHF radio waves.

  The electronic key 4 includes an unlock button 11 that is operated when the door 2 is unlocked by remote operation (wireless operation), and a lock button 12 that is operated when the door 2 is locked by remote operation (wireless operation). . The unlock button 11 and the lock button 12 are, for example, push buttons, and output an operation signal such as an ON signal or an OFF signal to the key control unit 7.

  For example, a plurality (two in this example) of doors 2 are provided in one or a plurality of buildings 1. In the case of this example, these doors 2 are referred to as a first door 2a and a second door 2b. The first door 2 a and the second door 2 b are connected by a communication line 13 provided in the building 1. Accordingly, the first door 2 a and the second door 2 b can transmit and receive various signals through the communication line 13. The communication line 13 is preferably a LAN (Local Area Network), for example.

  The door lock control system 5 includes a door lock 3 and a door lock operation unit 6, a controller 14 that controls the operation of the door lock control system 5, a transmission antenna 15 that transmits radio waves around the door 2, and the door 2. And a receiving antenna 16 for receiving radio waves in the vicinity. The unit of the door lock 3, the door lock operation part 6, the controller 14, the transmission antenna 15, and the reception antenna 16 is provided in each door 2 (the 1st door 2a and the 2nd door 2b). In the memory 17 of the controller 14, the ID (electronic key ID) of the electronic key 4 registered in the door 2 is written and stored. The transmission antenna 15 transmits, for example, LF radio waves. The receiving antenna 16 transmits, for example, UHF radio waves. The transmission antenna 15 and the reception antenna 16 are disposed on the door 2 or the building wall, for example. The door lock 3 is composed of, for example, an electric lock that inserts and removes a dead bolt using an actuator as a drive source. The controller 14 is a control panel in which various elements such as ICs and chips are mounted on a substrate, for example. The door lock operation unit 6 may be, for example, a lock / unlock switch that alternately locks / unlocks the door lock 3 each time it is operated.

  The door lock control system 5 includes a registration execution unit 18 that manages an operation when registering the electronic key 4 in the door 2. The registration execution unit 18 is provided in the controller 14 of the door 2. In the case of this example, the thing of the 1st door 2a is made into the registration execution part 18a, and the thing of the 2nd door 2b is made into the registration execution part 18b. When the registration execution unit 18 registers the electronic key 4 in one door 2 among the plurality of doors 2 electrically connected through the communication line 13, the registration execution unit 18 assigns the electronic key ID of the electronic key 4 to the communication line 13. The electronic key 4 is operated so that it can be shared by the plurality of doors 2 by registering with the other doors 2 through.

  The door lock control system 5 has a door lock interlocking function in which the door lock 3b of the second door 2b is also interlocked when the door lock 3a of the first door 2a is operated with the electronic key 4. The door lock interlocking function of this example is such that, for example, when the first door 2a positioned at the entrance door is locked, the second door 2b positioned at the front door is interlocked and locked.

  The door lock control system 5 includes an information output unit 21 that outputs an operation signal Sa notifying that to the other door 2 through the communication line 13 when the door lock 3a is operated by the first door 2a. The information output unit 21 is provided in the controller 14a of the first door 2a. When the door lock 3 a of the first door 2 a is operated, the information output unit 21 outputs an operation signal Sa indicating that the operation has been performed to the second door 2 b connected by the communication line 13. The operation signal Sa is a signal for notifying the second door 2b of what lock operation has been performed on the first door 2a.

  The door lock control system 5 includes an operation execution unit 22 that operates the door lock 3b of the second door 2b based on the operation signal Sa acquired from the information output unit 21. The operation execution unit 22 is provided in the controller 14b of the second door 2b. When the operation signal Sa is input from the information output unit 21, the operation execution unit 22 causes the second door 2b to perform the same operation as the first door 2a based on the operation signal Sa. In the case of this example, when the operation signal Sa of “the first door 2 a is locked” is input from the information output unit 21, the operation executing unit 22 is triggered by the input of the operation signal Sa. The lock 3b is automatically locked.

Next, operation | movement of the door lock control system 5 is demonstrated using FIG.2 and FIG.3.
FIG. 2 shows an outline of the operation when the electronic key 4 is registered in the door 2. Here, for example, a case where the electronic key 4 is registered in the first door 2a is taken as an example. In registering the electronic key 4 in the first door 2a, the operation mode of the first door 2a is first switched to “registration mode”. Switching to the registration mode may be realized, for example, by operating the door lock operation unit 6 with a predetermined operation pattern or operating a dedicated switch provided in the controller 14. Thereby, the registration execution part 18a of the 1st door 2a starts operation | movement.

  When switching to the registration mode, the registration execution unit 18a performs communication (key registration communication) using the communication network of the key operation free system between the first door 2a and the electronic key 4. The key registration communication is, for example, communication that can be executed by the controller 14 and the electronic key 4 in the registration mode, and confirms whether the communication standards of the general smart communication and the electronic key 4 and the controller 14 match. In order to ensure communication and security, encryption communication and the like are assumed. When the registration execution unit 18a acquires the electronic key ID from the electronic key 4 in the key registration communication, the registration execution unit 18a writes the electronic key ID into the memory 17 of the first door 2a, thereby registering the electronic key 4 in the first door 2a. .

  When the registration of the electronic key 4 is completed on the first door 2a, the first door 2a becomes the “master door”, and the operation of registering the electronic key 4 on the “subordinate door” of the second door 2b is executed. At this time, the registration execution unit 18a outputs an electronic key ID registration request Sdem to the second door 2b through the communication line 13 in the building 1. The electronic key ID registration request Sdem may include an electronic key ID acquired in key registration communication executed by the first door 2a and the electronic key 4 at the time of registration and a command for requesting the association of the electronic key ID. . When the electronic key ID registration request Sdem is input from the first door 2a, the registration execution unit 18b of the second door 2b writes the electronic key ID included therein into the memory 17 of the second door 2b, thereby causing the electronic key 4 to be registered. Register in the second door 2b.

  FIG. 3 illustrates a specific example of smart communication executed between the door 2 (first door 2 a) and the electronic key 4. As shown in the figure, the smart communication area (smart communication area Ea) is formed around the door around the door 2 (first door 2a). Thus, the smart communication area Ea of this example is formed in one zone over the interior and exterior of the building 1. The smart communication may be performed periodically (a certain repetition cycle) or on the condition of a trigger input (an example is an operation of the door lock operation unit 6).

  When the electronic key 4 enters the smart communication area Ea of the transmission antenna 15, smart communication is executed between the door 2 and the electronic key 4. Specifically, when the electronic key 4 receives the wake signal transmitted from the transmitting antenna 15, the electronic key 4 is activated and an ACK is returned by UHF radio waves. In the subsequent communication process, door ID verification, challenge response authentication, Various verifications of electronic key ID verification are executed. The door ID collation is a collation in which a door ID (not shown) that is a unique ID of each door 2 is transmitted to the electronic key 4 so that the electronic key 4 confirms the door ID. In the challenge response authentication, a challenge code whose code is changed every time it is transmitted is transmitted from the door 2 to the electronic key 4 and passed through the encryption key of the electronic key 4, and this response code is returned to the door 2. This is verification for confirming the validity of the response code of the electronic key 4 based on the calculated response code. The electronic key ID collation is a collation in which the validity of the electronic key ID registered in the electronic key 4 is confirmed by the door 2. When it is confirmed that all of these verifications are established, smart verification is established.

  When the controller 14a detects that the locking operation of the first door 2a (for example, the operation of the door locking operation unit 6) is performed in a situation where the door lock 3a is unlocked, the smart verification is established. On the condition, the door lock 3a is switched to locking. That is, the door lock 3a is locked by a key-free operation (smart operation). Note that the locking operation of the first door 2a may be executed by operating (wireless operation) the locking button 12 provided on the electronic key 4. When the door lock 3a performs the locking operation, the thumb turn 24 of the door 2 also rotates to the locking position in conjunction with the operation.

  When the information output unit 21 confirms that the door lock 3a is locked in the first door 2a, the information output unit 21 outputs an operation signal Sa notifying the fact to the second door 2b to the second door 2b through the communication line 13. The operation signal Sa of this example is a signal for notifying the second door 2b that the first door 2a is locked by the smart operation.

  When the operation execution unit 22 of the second door 2b receives the operation signal Sa from the information output unit 21 of the first door 2a, the operation execution unit 22 operates the door lock 3b of the second door 2b based on the operation signal Sa. In the case of this example, the operation executing unit 22 switches the unlocked door lock 3b to locking. Thus, when the door lock 3a is locked by the first door 2a, the door lock 3b of the second door 2b is automatically locked in conjunction with this.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) When the door lock 3a is locked in the first door 2a, an operation signal Sa for notifying the second door 2b is output from the first door 2a to the second door 2b through the communication line 13.
