Abstract

The invention discloses a base station data processing method of a flight data real time monitoring system. After a hardware device of the base station receives flight data, the flight data is transmitted for processing through an udp protocol. The base station data processing method comprises steps of decoding the data, extracting control information, performing crc verification, determining whether a data pack is an error data pack, if yes, removing the error data pack, comparing the extracted control information with control information in a buffer memory to determine whether the control information is duplicate information, if yes, removing the duplicate information, and transmitting a data pack after analysis and reduction to a display front end or a monitoring server through the udp protocol for further processing. The data instantaneity and a data processing capability are greatly improved, data safety is enhanced and system expandability is very strong.

Description

technical field [0001] The invention relates to the field of flight data monitoring, in particular to a base station data processing method and system of a flight data real-time monitoring system.
