For boarding bridges, the system defines valid time periods. Outside the valid time period, anti-entry detection laser scanners are used to prohibit any personnel from entering; a two-dimensional laser scanner XD-TOF-05D is used to monitor the area above the automatic boarding gate, and the laser scanner is activated when access is not allowed. Any attempt to climb the boarding gate will immediately trigger an alarm signal.
Analysis of the design of intelligent security system for boarding bridges (based on the technical standards of 2025)
I. System operation mechanism and time-space control
Definition of dynamic effective time periods
Based on the airport flight schedule, set the boarding bridge activation window (usually 30 minutes before the flight arrives and 15 minutes after takeoff)
Integrate the airport central dispatch system to achieve automatic time period update, with an error accuracy of <0.5 seconds
Automatically start three-level protection during non-operating time periods: warning area isolation (10 meters) + equipment self-test (5 minutes) + backup power supply switching
Three-dimensional protection system
Ground layer protection: Use XD-TOF-05D two-dimensional laser scanner to build a monitoring network with an angular resolution of 0.1°, covering an area of 0-2.5 meters in height
Aerial layer protection: Deploy a pulsed anti-entry laser array (wavelength 905nm, Class 1 safety level) to form a non-visible light curtain wall
Structural layer monitoring: Embed stress sensors at the boarding gate shaft to detect abnormal mechanical parameters in real time (sensitivity up to 0.01N·m)
