And a receiving antenna 13 for receiving radio waves in the vicinity. An ID (electronic key ID) of the electronic key 4 registered in the door 2 is written and stored in the memory 14 of the controller 11. The transmission antenna 12 transmits, for example, LF radio waves. The receiving antenna 13 receives, for example, UHF radio waves. The transmission antenna 12 and the reception antenna 13 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 11 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 person detection sensor 15 that detects the presence or absence of a person near the door 2. The human detection sensor 15 includes, for example, a temperature sensor, and detects a person by detecting a temperature difference between the human body and the surroundings, for example. The human detection sensor 15 is disposed in the room by being installed on, for example, the inner wall of the door 2. The human detection sensor 15 is connected to the controller 11 to output a human presence / absence detection signal Sh to the controller 11. Specifically, the human detection sensor 15 outputs a detection signal Sh (H level signal) to the controller 11 when detecting a person, and does not output the detection signal Sh to the controller 11 when no person is detected (L Level signal).

  The door lock control system 5 includes a smart authentication unit 16 that performs wireless ID verification (smart verification) with the electronic key 4 and communication with the door 2 side, and a lock control unit 17 that controls the operation of the door lock 3. Prepare. The smart authentication unit 16 and the lock control unit 17 are provided in the controller 11 of the door 2. The smart authentication unit 16 executes smart communication on the condition of regular (a certain repetition cycle) or trigger input (for example, operation of the door lock operation unit 6), and confirms whether smart verification is established. To do. The lock control unit 17 switches between locking and unlocking the door lock 3 based on the authentication result of the smart authentication unit 16.

  As shown in FIGS. 2A and 2B, the smart communication area (smart communication area E <b> 1) by the transmission antenna 12 is formed around the door 2 around the door 2. As described above, the smart communication area E1 of this example is formed in one area across the interior and exterior of the building 1.
