In view of the situation that the existing node acquisition system of flight operation support cannot fully collect all operation nodes and cannot completely replace manual work, this paper proposes the data acquisition of different nodes of flight support, uses different data acquisition equipment, and then realizes the intelligent collection of flight operation node data through the research of multi-source sensor data fusion technology. The research and application of this technology can greatly improve the airport operation management ability, actively realize the load balance of airport operation resources, improve the accuracy and coverage of node collection, and improve the automation level of airport flight support node collection.
