| Abstract: | The structure and the function of the airport freight transportation monitoring system are presented,and two key technologies of airport freight transportation monitoring system, the mulit-task control and real-time communication are deeply researched. The multi-task control technology refers to using multi-thread technology to parallel process many duties, and the real-time communication technology mainly includes using the asynchronous request technology to realize the superior machine dispatch and the lower position machine correspondence separation and using OPC standard interface technology to realize the multi-PLC real -time comnmnicotion technology. The application of this technology to some large-scale airport is summarized. |
