An anti-hijacking system and method

Abstract

The present invention proposes an anti-hijacking system and method for public transport. The anti-hijacking system includes an information collection and transmission subsystem, a handheld terminal, and a command center. The information collection and transmission subsystem at least integrates information collection and information transmission. , positioning and tracking three modules, the information collection module includes micro audio, video image collection equipment and related control modules; the information transmission module includes the maritime satellite communication module and the broadband wireless communication module; the information collection module installed in the hidden place of the inner wall of the public transport To collect tactical reconnaissance information in public transportation, the handheld device relies on the communication module to realize signal transmission with the command center, and uses the Beidou positioning module to realize positioning and tracking.

Description

technical field [0001] The invention relates to an anti-terrorist attack reconnaissance system and method, in particular to an anti-hijacking tactical reconnaissance system and method for public transport vehicles, such as passenger planes. Background technique [0002] With the deepening of reform and opening up, my country is currently facing a relatively severe anti-terrorism situation. The "three evil forces" at home and abroad, international terrorist forces, and some violent elements who are dissatisfied with the social status quo pose a real threat to national security and social harmony and stability. situation. In recent years, civil aviation airliners and other public transportation have become the main potential targets for violent terrorists to carry out hijacking operations. How to successfully rescue these targets after being hijacked has always been a worldwide problem. Several successful rescues are also based on the effective grasp of various types of infor...

Problems solved by technology

[0007]The first option is to install sprayers on the aircraft, and the crew members wear the clothes of the sprayers, and subdue criminals by spraying specific liquids or aerosols , this method has obvious defects: first, it will affect the use of cabin equipment and threaten flight safety; Third, in the case of false alarms or control failures, it may cause accidental injury to passengers

This patent has limited significance in practical application, and even if it is applied in the future, it can only be used as an auxiliary means

[0008]The second solution is to analyze whether passengers are in a state of tension by collecting and analyzing facial expressions of passengers, and then further analyze the specific causes of tension, through the internal closed circuit The TV system alerts the flight crew in time. This method also has many difficulties and defects: First, it needs to install a large number of equipment on the aircraft. Existing aircraft cannot perform such an expensive major operation. The entire system can only be installed in a new aircraft. Second, how to accurately analyze the "meaning" of human facial expressions is an international problem, and it is difficult to break through in the short term; third, in the process of system application, if "over-sensitive" is set, the alarm will often be falsely reported, causing the The crew is repeatedly in the state of "wolf is coming", affecting normal flight services, or missing threats due to "insensitive"; fourth, the system can only provide closed-circuit television information to the crew, and cannot send information to the crew in the case of hijacking. External real-time transmission of information cannot help the outside world fully understand the dynamics in the cabin. It is only a means of prevention or early warning, and it cannot achieve real "anti-hijacking"; fifth, the facial expressions of passengers are collected and analyzed throughout the flight. Can effectively protect the privacy of passengers
