Abstract


With the rapid development of the domestic civil aviation market , the airport and out of the number of visitors is increasing , requiring the airport to be able to give travelers into port to provide more effective and efficient , departure services , automatic baggage sorting system is one of the core areas . Luggage into the system as a subsystem of the automatic baggage sorting system , the import rate directly affect the efficiency of the baggage conveyor , and therefore has important implications on luggage import subsystem . First introduced the progress and development of the airport automatic baggage sorting system , gave a detailed description of the structure and function , and the entire system . Focus depth research on luggage import subsystem : the baggage of the passenger check-in system convergence virtual window concept and design of the two control algorithms , Window control and Gap control . A detailed analysis of the principles of the two algorithms , wherein Window Control been applied in practice . 2 to establish Luggage Import sorter mathematical model , by means of theoretical calculations , based on the length of the motor running speed and the conveyor belt , motor run time parameters . Using VVVF and synchronization control the luggage smoothly import luggage tray . Separate motor control and load mutation motor can not run simultaneously , using fuzzy PID control based compensation . Simulation results verify the effectiveness and practicality of this control algorithm , to meet the needs of the system . 3 of the baggage sorting system functional requirements analysis, design The Siemens PLCS7-400 automatic baggage sorting control system , the hardware modules of the system based on the fieldbus PROFIBUS-DP network communications using a distributed I / O modules on control field devices . The system software is divided into lower control and host monitoring two parts . Lower -based modular programming , which greatly improves readability and versatility of the program . Upper WinCC configuration software platform and global script , and monitor the entire baggage handling . Finally, the summary of the research work done , a simple analysis of the other problems in the automatic baggage sorting system , prospects for future research directions .
