Abstract
An access control system includes a plurality of door control systems each associated with an access door and including a relay control for operating the access door and a transmitter for eliciting a radio response from a tag at the access door. The response includes a tag ID and an access door ID. A receiver is operable to receive radio responses from tags at a plurality of access doors. An access door controller is coupled to the receiver and operable to receive the tag ID and the access door ID included in each radio response received by the receiver. The access controller determines whether access by the tag at the access door is authorized and controls the relay door to permit authorized access.
Claims26
An access control system, comprising:
- a plurality of door control systems each associated with at least one of a plurality of access doors and comprising a relay control for operating the access door and a transmitter for eliciting a radio response from a tag at the access door, the response including a tag ID and an access door ID, a plurality of the access doors associated with a facility;
- a receiver operable to receive radio responses from tags at a plurality of the access doors;
- and
- an access controller coupled to the receiver and operable to receive the tag ID and the access door ID included in each radio response received by the receiver, to determine whether access by the tag at the access door is authorized, and to control the relay control to permit authorized access.
A secure facility, comprising:
- a plurality of access doors in the secure facility for accessing at least one of the facility and one or more areas within the facility;
- a door control system associated with each of the access doors and comprising a relay control for operating the access door and a transmitter for eliciting a radio response from a tag at the access door, the response including a tag ID and an access door ID;
- a receiver operable to receive radio responses from tags at a plurality of the access doors;
- and
- an access controller coupled to the receiver and operable to receive the tag ID and the access door ID included in each radio response received by the receiver, to determine whether access by the tag at the access door is authorized, and to control the relay control to permit authorized access.
A method for controlling access to a facility, comprising:
- eliciting a first radio response from a first tag at a first access door in the facility, the first response including a first tag ID and a first access door ID;
- eliciting a second radio response from a second tag at a second access door in the facility, the second response including a second tag ID and a second access door ID;
- receiving the first and second radio responses from the first and second tags at a shared receiver;
- determining whether access by the first tag at the first access door is authorized based at least partially on the first response;
- determining whether access by the second tag at the second access door is authorized based at least partially on the second response;
- and
- controlling the access doors to permit authorized access.
