Definitions

  • the present invention generally relates to an electric lock system and an electric lock device, and more particularly relates to an electric lock system configured to unlock an entrance of a building with an electric lock device by making the electric lock device communicate with a key device, and also relates to an electric lock device for use in such an electric lock system.
  • the electric lock system disclosed in Patent Document 1 includes an electric lock device and a mobile device.
  • the electric lock device includes a sensing unit, a first communications unit, a driving unit for driving a lock, and a control unit.
  • the mobile device includes a memory and a second communications unit. With the memory of the mobile device, registered in advance is authentication information, which is required to shut or open the lock.

  • An electric lock system 10 includes a key device 1 and an electric lock device 2 as shown in FIGS. 2A and 2B .
  • the electric lock device 2 is a device for locking the entrance 4 of a building 3.
  • the "entrance" of the building 3 refers to a door or a window separating the inside of the building 3 (hereinafter referred to as "the inside 31") from the outside of the building 3 (hereinafter referred to as "the outside 32") and may be a main entrance door, a back door, or a patio door, for example.
  • the electric lock device 2 is installed on the entrance 4.
  • the electric lock device 2 is configured to be able to communicate with the key device 1 and electrically switch the state of the entrance 4 from a locked state into an unlocked state, and vice versa, by communicating with the key device 1.
  • the key device 1 has the capability of communicating with the electric lock device 2.
  • the method of communication between the key device 1 and the electric lock device 2 is wireless communication via radio waves.
  • the key device 1 is battery driven and formed in an appropriate size so as to be easily portable for a user 5.
  • the key device 1 is configured as a tag attachable to a bag or any other type of personal belonging carried by the user 5 with him or her.
  • the building 3 is a single-family dwelling house
  • the user 5 is one of the persons living in the building 3 (the single-family dwelling house in this example) who holds (or carries) the key device 1.
  • the basic function of the electric lock system 10 is allowing the electric lock device 2 to unlock the entrance 4 by making the key device 1 transmit a key ID (identification), which is stored in advance in the key device 1, to the electric lock device 2. That is to say, successful authentication of the key device's 1 key ID through the communication between the key device 1 and the electric lock device 2 makes the electric lock device 2 ready to unlock the entrance 4. Then, once the authentication has been done successfully, it is not until the first operating unit 25 or the second operating unit 26 (see FIG. 1 for both of these units) finishes a predetermined operation (i.e., unlocking operation) that the electric lock device 2 unlocks the entrance 4. Consequently, the electric lock device 2 performs the unlocking operation of switching from the locked state into the unlocked state through the communication with the key device 1.
  • the key ID described above is used as a piece of authentication information of the key device 1.
  • Such an unlocking operation is performed by the electric lock device 2 when the user 5 stays outdoors, or is in the outside 32 (i.e., when the user is coming home) and/or when the user 5 stays indoors, or is in the inside 31 (i.e., when the user is going out).
  • the unlocking operation is performed by the electric lock device 2 both when the user 5 is coming home and when the user 5 is going out. Specifically, when the user 5 is coming home, communication between the electric lock device 2 and the key device 1 held by the user 5, who is still staying in the outside 32 but who has come close enough to the entrance 4 for radio waves to reach the electric lock device 2 from the key device 1, makes the entrance 4 ready to be unlocked.
  • the electric lock device 2 locks the entrance 4. That is to say, the electric lock device 2 is able to perform not only the unlocking operation but also the locking operation of switching its own state from the unlocked state into the locked state through the communication with the key device 1.
  • the key device 1 includes a key-end communications unit 11, a control unit 12, and a storage unit 13.
  • the storage unit 13 may be implemented as a nonvolatile memory, for example.

  • the method of communication between the key-end communications unit 11 and (a lock-end communications unit 21 of) the electric lock device 2 may be wireless communication via radio waves such as BluetoothTM radio waves.
  • the key device 1 not only transmits signals to the electric lock device 2 but also receives a connection request signal, an ID request signal, and other signals from (the lock-end communications unit 21) of the electric lock device 2. That is to say, the key-end communications unit 11 has signal transmitting and receiving capabilities and communicates bidirectionally with the lock-end communications unit 21.
  • control unit 12 is implemented as a microcomputer including, as its major components, a central processing unit (CPU) and a memory.

  • the control unit 12 allows the entrance 4 to be unlocked by the electric lock device 2 at least by making the key-end communications unit 11 receive a signal from (the lock-end communications unit 21 of) the electric lock device 2.
  • the control unit 12 makes the key-end communications unit 11 receive a connection request signal from the lock-end communications unit 21.
  • the connection request signal is transmitted to have the communication between the key-end communications unit 11 and the lock-end communications unit 21 started.
  • the control unit 12 has an ACK (acknowledgement) signal transmitted as a response signal from the key-end communications unit 11 to the lock-end communications unit 21.
  • the control unit 12 When communication is established between the key-end communications unit 11 and the lock-end communications unit 21, the control unit 12 reads out the key ID from the storage unit 13 and makes the key-end communications unit 11 transmit a signal including the key ID (hereinafter referred to as an "ID signal") to the lock-end communications unit 21.

  • the electric lock device 2 may operate with power supplied from an external power supply such as a utility grid (commercial power supply) or may be driven by a battery.
  • the lock-end communications unit 21 is configured to be able to communicate with (the key-end communications unit 11 of) the key device 1.
  • the lock-end communications unit 21 and (the key-end communications unit 11 of) the key device 1 communicate with each other bidirectionally as described above, and therefore, the lock-end communications unit 21 has signal transmitting and receiving capabilities.
  • At least one registration ID is registered with (or stored in) the authentication unit 23.
  • the registration ID corresponds to the key ID of the key device 1. For example, if each of the residents of the building 3 has their own key device 1 individually (i.e., if the electric lock system 10 includes a plurality of key devices 1), then a plurality of registration IDs respectively corresponding to the key IDs of those key devices 1 are registered with the authentication unit 23.
  • the lock driving unit 24 switches the state of the electric lock device 2 from the locked state into the unlocked state, and vice versa, by driving the lock of the entrance 4.

  • ID request signal a signal requesting a key ID
  • the lock-end communications unit 21 When the lock-end communications unit 21 receives a signal including the key ID (hereinafter referred to as an "ID signal") in response to the ID request signal, the signal processing unit 22 instructs the authentication unit 23 to collate the key ID included in the ID signal with the registration ID registered in advance with the authentication unit 23, thus performing authentication processing on the key ID.
  • the signal processing unit 22 controls the lock driving unit 24 to unlock the entrance 4, which is triggered, in this embodiment, by a predetermined operation (i.e., an unlocking operation) performed on the first operating unit 25 or the second operating unit 26.

  • the second operating unit 26 is provided in the inside 31 of the entrance 4, and therefore, is usually operated by the residents of the building 3. That is why to unlock the entrance 4 from the inside 31, the authentication processing does not have to be performed on the key ID of the key device 1. Nevertheless, the authentication processing may or may not be performed on the key ID of the key device 1 when the entrance 4 is unlocked from the inside 31.

  • the predetermined condition may be that the main entrance door to serve as the entrance 4 be once opened and then shut again, for example. In that case, it is presumed that the user 5 has entered the inside 31 from the outside 32 by passing through the entrance 4. Therefore, when finding that this condition is satisfied, the decision unit 221 decides that the key device 1 be currently located indoors (i.e., in the inside 31 of the building 3). Nevertheless, this condition alone does not always allow a final decision to be made that the key device 1 be currently located in the inside 31. For this reason, the decision unit 221 actually presumes that the key device 1 would be currently located in the inside 31.
  • the second operating unit 26 is provided for the inside 31 of the entrance 4 as described above. That is to say, the user 5 is supposed to perform the unlocking operation on the second operating unit 26 from the inside 31.

In that case, it is presumed that the user 5 has gone out from the inside 31 into the outside 32 by passing through the entrance 4. Therefore, when finding that this condition is satisfied, the decision unit 221 decides that the key device 1 be currently located outdoors (i.e., in the outside 32 of the building 3).
