Abstract
The present application concerns access control for controlling unlocking of a door (102) at the presentation of credentials (108) at the door. A credentials relay unit (112) and a lock controller (114) are mounted in the vicinity of the door. The credentials relay unit transmits received credentials to a pre-configured, first network address, and in addition transmits a wake-up signal (122) to the lock controller, which upon receipt of the wake-up signal will transmit a request (126) for instructions to a pre-configured, second network address. In response to the request, the lock controller receives unlocking or no-action instructions (128a, 128b), and in case unlocking instructions are received, the lock controller transmits an unlocking signal (132).
Claims13
An access control system for controlling unlocking of a door at the presentation of credentials at the door, the access control system comprising a credentials relay unit and a lock controller which are mounted in the vicinity of the door,
- wherein the credentials relay unit comprises an input interface and a first network interface,
- wherein the credentials relay unit is configured to receive credentials via the input interface, and transmit the credentials to a pre-configured, first remote network address via the first network interface, in response to receiving the credentials via the input interface,
- wherein the credentials relay unit and the lock controller have a local communications interface, and the credentials relay unit is configured to transmit a wake-up signal to the lock controller via the local communications interface, in response to receiving the credentials via the input interface, and wherein the credentials relay unit is configured to not transmit credentials or unlocking instructions to the lock controller,
- wherein the lock controller comprises a second network interface, and is configured to, in response to receiving the wake-up signal, transmit, via the second network interface, a request for instructions to a pre-configured, second remote network address and receive, via the second network interface, unlocking or no-action instructions,
- wherein the lock controller comprises a lock control interface and is configured to transmit a signal to unlock the door via the lock control interface, in response to receiving unlocking instructions via the second network interface,
- wherein the system further comprises a remote authorization server, and wherein the pre-configured first network address and the pre-configured second network address point to the remote authorization server.
A method of controlling unlocking of a door upon presentation of credentials at the door, the method comprising:
- a credentials relay unit receiving the credentials, and transmitting the credentials to a pre-configured, first network address,
- the credentials relay unit transmitting a wake-up signal to a lock controller, without transmitting the credentials or unlocking instructions to the lock controller,
- the lock controller transmitting, in response to the wake-up signal, a request for instructions to a pre-configured, second network address, and receiving unlocking or no-action instructions from the second network address,
- the lock controller, upon receipt of unlocking instructions, transmitting a signal to unlock the door,
- wherein the pre-configured first network address and the pre-configured second network address point to a remote authorization server.
