Research Of Security Inspection Equipment Remote Monitoring System Based On RFID

The security inspection equipment of civil aviation is the key facility to ensure the air safety and smooth, efficient function of the airport inspection. Owing to the growing size and capacity of the airport, the continuous change of the international situation, the number and varieties of security inspection equipment are experiencing large amount of growth. And the integrated management of security inspection equipment dramatically improves the administrative efficiency. Unfortunately, there are no similar products or system in our country.First, this thesis analyses the varieties and function of the security inspection equipment in China and abroad. According to the characteristics they are divided into two parts, fixed and moving types. And based on RFID the plan of remote monitoring and management is proposed. Next, based on data acquisition terminal and wireless sensor network, remote monitoring stage, the system architecture is designed. This design with data collection hardware system built-in, which formed security inspection wireless sensor network of single terminal based on ZigBee, not only presents networking process and parameter configuration of the wireless network, but also makes a specific demonstration of the technology of the current transformer, infrared count and RFID tag. Third, aimed at the positional requirement of hand-held metal detector, this thesis studies the currently used algorithm of indoor positon and proposed an improved weighted-centroid algorithm that has better node localization. And this paper applies to the Matlab simulation to verify it. Fourth, in this design remote monitoring platform based on the LabVIEW security inspection devices is released to the LAN workstation by function of Web Server. In this way, all users in LAN could monitor the security inspection devices. Finally, the paper elaborates some parts of experiences. And the result shows that the system not only could meet the monitoring management requirement of airport security inspection devices, but also could meet the application requirements of airport in China.
