INGRESS/EGRESS CONTROL SYSTEM FOR AIRPORT CONCOURSES AND OTHER ACCESS CONTROLLED AREAS

摘要

An ingress/egress control system (10) controls passenger (P) flow into and outof an airport concourse. Enplaningpassengers pass through an entrance portal (18) on their way to an airplanegate. A security screen (22) screens each person passingthrough the portal for the presence of prohibited items and identifies anyperson suspected of carrying such an item. A secondaryportal (50) is located downstream of the first portal. A visual display system(52) responds to an indication from the security screeningto route a suspected person from the first portal to the secondary portal, forfurther screening to determine if the person is carryinga prohibited item, while providing a different display to passengers passingthe security screen so they can enter the concourse. Aseparate, exit portal (64) is provided for deplaning passengers exiting theconcourse. Multiple detectors (42a'-42b', 82, 88) continuouslymonitor this portal so people cannot inadvertently or intentionally intrudeinto the exit path. Audio and visual alarms (79, 92)are activated when someone attempts to enter the concourse through the exitportal to both warn the person away and to alert securitypersonnel of a possible intruder. An imaging system (VM) is used to obtain andstore a video of image of the intruder.
