Embodiment Construction

[0024] The invention specifically establishes a new generation of high-thrust carrier rocket large-flow telemetry data processing model, including a telemetry data preprocessing model and a bus data real-time processing model.

[0025] 1. Establish a telemetry data preprocessing model to sort and classify telemetry data in real time

[0026] ①From the telemetry original code data, only the data part that can be processed in real time is selected and forwarded to the data processing system.

[0027] If the telemetry original code frame is regarded as a two-dimensional matrix, the data part that can be processed in real time is relatively concentrated in the telemetry frame. Afterwards, it is rearranged into a new smaller matrix, restored to the network data packet format, and then forwarded to the data processing system. This method is applied to the telemetry processing of a certain type of rocket in active service. If the two-dimensional matrix of the telemetry original code...

Abstract

The invention discloses a large-thrust rocket large-flow telemetry data processing method, which is dedicated to quickly and accurately solving the large-flow telemetry data, and has good effect in practical applications. Including the establishment of a telemetry data preprocessing model to sort and classify the telemetry data in real time; the establishment of a bus data real-time processing model to real-time solve the bus data that accounts for a large amount of traffic in the telemetry data. At the same time, the effectiveness was verified. The model established by this method is also applicable to the telemetry data processing of active rockets. It has been verified in the actual combat missions of active rockets and the joint training missions of new-generation high-thrust launch vehicles. The method is accurate and efficient.

Description

technical field [0001] The invention relates to the field of remote measurement data processing of rockets, in particular to a method for processing telemetry data of large-thrust rockets and large flows. Background technique [0002] The new generation of high-thrust launch vehicles can complete the launch tasks of various spacecraft such as low-earth orbit satellites, geosynchronous transfer orbit satellites, sun-synchronous orbit satellites, space stations and lunar probes, and will surely become the main rocket model in my country's aerospace field. The carrying capacity of my country's new generation of high-thrust launch vehicle is two to three times that of the largest launch vehicle in active service. In terms of the design of its measurement system, the flow of telemetry data is also several times that of active launch vehicles. [0003] The telemetry data flow of the new generation of high-thrust launch vehicle is very large. Calculated based on one device receivin...
