Problems solved by technology

This method cannot process relevant data in a timely manner, and can only meet offline analysis after the event, and cannot complete the on-orbit real-time data comparison, processing and analysis of flight control tasks
[0004] In addition, based on the current storage method of structured database data, the acquisition process takes a long time, and it is difficult to meet the needs of real-time data comparison and interpretation, forecasting and forecasting processing
The time to extract data from the database is greatly affected by the structured storage method of the database storage table and the number of storage variables. In the past, the overall layout of data storage and the storage method of parameters in relational databases were classified according to data packets. When reading Acquiring the corresponding variable data is slow when the data is large, and it takes a long time to process variable data with a large amount of data. It is impossible to perform real-time status comparison and forecasting and forecasting processing operations on the data in the above processing method.

Abstract

The invention discloses a data fusion and association processing method, which comprises the following steps: reading a system setting configuration file, and carrying out initialization operation according to the state of a system; wherein the initialization operation comprises memory database initialization and configuration operation initialization; analyzing the received source data to obtainan analysis result; storing the analyzed source data according to the data packet or the data variable carried in the analysis result; obtaining corresponding variable data according to a service initialization result, and loading historical data; and outputting a loading result on a display interface in a curve and / or numerical mode. According to the method and the system, associated storage of multi-source and heterogeneous data and rapid acquisition of specified data are realized, and the method and the system have important significance for ground data interpretation and processing in real-time flight control of spacecrafts.

Description

technical field [0001] The invention belongs to the technical field of spacecraft ground flight control and support, and in particular relates to a data fusion and association processing method. Background technique [0002] When facing the flight control mission of space vehicles, the analysis and comparison of relevant flight mission control data is of great significance to the judgment of the flight mission status. The so-called relevant flight control mission data includes real-time telemetry data transmitted through different channels, historical data stored in the database, simulation processing data, target aircraft test experiment data and other flight mission data or data compared with the flight mission. [0003] At present, in the flight control link of spacecraft, these flight control data are scattered and stored in their respective relatively independent systems (for example, real-time flight control data and historical flight control data are stored in the fli...
