Abstract: The air-port monitoring system can realize the monitoring of the Um interfaces on the ground, and the Igsm-r and Um interfaces on the vehicle. It can be combined with the existing CTCS-3 wireless interface monitoring system to realize the full interface coverage of vehicle and ground and provides a basis for the precise location and intelligent analysis of faults. This paper discusses the system structure and function design of the air port monitoring system, and elaborates the key technologies such as air port data acquisition and analysis technology based on wireless module array, GPS and Beidou parallel timing technology, and ATO service monitoring. Finally, the field deployment experience of the system acquisition equipment is introduced based on the practical application.
