  • the field of access control systems encompasses conventional mechanical locks with keys mechanically adapted to operate such locks and electronic lock systems where keys interact with electronic locks by utilizing electric signals transferred between a lock and a key.

  • the system may record operational failures so as to detect faulty components in the access control system, and the system may also record information that the user has tried to access a lock to which (s)he has no access rights.
  • the control circuitry of the key may be configured to transfer a message of a successful entry to a given lock to the ASP server for location tracking purposes.
  • a message may comprise an indication of the successful entry and an identifier of the lock which has been successfully opened.
  • the transfer of such a message may be triggered by the acknowledgment message received from the lock as a result of the successful entry.

  • the server may store a layout of the premises of the access control system where physical locations of the electromechanical locks have been stored. When the server receives information on the lock a given key has accessed, it may map the key to a given location when the server knows the physical location of that lock.

  • the ASP server is further configured to count a time of presence of a given personal electronic device from access information received from the keys of the staff.
  • the location tracking may be used for monitoring and storing the working time of each member of the staff on the basis of the time duration the staff member is detected to have been in the premises of the area where the location tracking is carried out.

  • the location tracking may be utilized for other purposes as well.
  • the user's cellular phone (or another communication device or devices) may be linked to the location tracking system and to the ASP server. This enables a given user to establish a voice connection to a selected place, instead of a selected phone number.
  • the user may establish a call which is routed to the ASP server, wherein the call establishment includes transfer of a message comprising an identifier of a location to which the caller wishes to give call.
  • the ASP server checks the location tracking records in order to find out another user closest to the desired location and, upon finding such a user, the ASP server routes the call connection to that user's cellular phone (or another communication device).

  • the key may still verify that it has appropriate access rights periodically or when a lock is being accessed.
  • the key Upon reception of the updated access codes from the server, the key modifies the stored access codes so as to make them up-to-date.
  • the transfer of the updated access codes and lock identifiers from the server to the key may include all the key identifiers and corresponding access codes to which access is granted every time the access rights update is carried out. If the update includes addition of one or more new access rights, only new access codes and lock identifiers may be sent to the key and no old access rights which have already been transferred need to be sent again. Similarly, if the update includes deletion of access rights, the ASP server may send a message indicating which access rights (access code and lock identifier) need to be deleted. This reduces the amount of data traffic, since transfer of redundant information is reduced.
  • the key may be configured to attempt reestablishment of the connection. If the reestablishment is not successful within a determined duration or number of attempts, the control circuitry of the key may be configured to irrevocably erase the access rights from the memory. The control circuitry may alternatively erase the access rights immediately upon losing TCP/IP connection with the server. As a consequence, the access codes will be deleted immediately if the user's key is stolen and the connection to the cellular phone or wireless network is lost or if the connection to the ASP server is otherwise lost. This improves the security of the system.
  • the whole operation for retrieving the access rights and communicating with the lock so as to enter the access code is carried out automatically without any user interaction.
  • the user only has to bring the counterpart interfaces provided in the electromechanical key and the lock into connection with one another, and then open the door, latch, or another element the lock protects.
  • the user convenience and speed of opening the lock is improved, as the complexity of the procedure is reduced.
  • the process or method described in Figure 3 may also be carried out in the form of a computer process defined by a computer program.
  • the computer program may be in source code form, object code form, or in some intermediate form, and it may be stored in some sort of carrier, which may be any entity or device capable of carrying the program.
  • Such carriers include a record medium, computer memory, read-only memory, electrical carrier signal, telecommunications signal, and software distribution package, for example.
  • the computer program may be executed in a single electronic digital processing unit or it may be distributed amongst a number of processing units.
  • the present invention is applicable to any access control system utilizing electromechanical locks.
  • the electromechanical locks require no connection with the server, and in some embodiment they do not even require batteries as the energy needed for the authentication and opening the lock is provided by the user with mechanical motion. This facilitates the installation of the system. Otherwise, the installation is very simple.
  • the database of the server is constructed to contain the access rights for the users/keys.
  • the keys are preconfigured to carry out the operations described above.
