Safety guarding information system for airport aviation area

Abstract

A security information system of a flight area of an airport comprises a perimeter detection subsystem, a video monitor subsystem, an audio broadcasting subsystem, a communication transmission subsystem, a central control subsystem and a remote control subsystem. The system resolves the problem of 'isolate island' phenomenon among subsystems in a former system and improves the cooperativeness and the response capability of police service of the whole system. The system organically combines all components through the communication transmission subsystem to realize coordination working of all the subsystems immediately when an alarm occurs, thereby forming a close, complete and perfect security information system. By adopting the double loop bus technology and the optical fiber as information transmission carrier and applying processing of computer digital signals, video imaging and audio signals, the system realizes a field integrated information system with a unification of three nets. The system has the advantages of strong stability, high sensitivity, high intelligence and convenient operation and maintenance, etc.

Description

Technical field [0001] The invention relates to a security protection system for airports, in particular to a network information system which can be used for security protection in the flight area of ​​airports. Background technique [0002] In the security system of the prior art, each branch part presents an "island" phenomenon, and each part generally exists only to realize a specific function, and cannot be compatible and integrated with each other. This independent state affects the overall coordination of the system and the response time of the police. When dealing with alarm problems, it is impossible to achieve the linkage effect of "pulling one hair and moving the whole body". In the perimeter defense of the flight area, the original method mostly used vibrating cables and infrared beam detectors for defense, and traditional bullet cameras were used for auxiliary video monitoring. This precautionary measure, first, electromagnetic interference (EMI) and radio fre...

AI Technical Summary

Problems solved by technology

This preventive measure, first, electromagnetic interference (EMI) and radio frequency interference (RFI) have a great influence on the sensitivity of the vibrating cable, which is prone to false alarms and false alarms, and consumes a lot of power; second, infrared radiation Although the special material shell of the detector can filter out the interference of white light, it can’t do anything about the infrared part of the light interference source, especially when using ordinary transmissive or reflective lenses for focusing infrared light, when focusing infrared rays of a specific wavelength, At the same time, the light of all the characters is also focused, so it is still easy to cause false alarms; thirdly, in terms of auxiliary video surveillance system, the traditional bullet camera is large in size, the pan / tilt rotates slowly and has dead angles, so it cannot be locked quickly and accurately The target cannot achieve the effect of dynamic monitoring of the flight area without blind spots
