Abstract

An airport enclosures intrusion detection system was proposed. Laser was used as detection means of alarm information in the system, intrusion event and region were detected through various means such as laser signal processing, visual information, information fusion and decision, etc., the alarm will be send to monitor center in time through CAN (Controller-area network) bus network and ethernet. The system has the following features: high sensitivity, good stability, strong anti-interference, low implementation and low maintenance costs, without interference to airport equipment, flexible, etc., and it can achieve continuous security monitoring while raining, snowing or fogging, the reliability of the system was improved by a wide margin.

Key words: Airport enclosures, laser, intrusion detection, alarm system.
