Conversion method of control data of aircraft

Abstract

Disclosed is a conversion method of control data of an aircraft. According to the method, a template control file is used to acquire control parameters from a control data text file; a read trajectory program angle of each time point is subjected to analysis and extension to generate processed trajectory program angle data; according to a read navigation parameter and a guide constant coefficient of each time point, a trajectory guide variable coefficient corresponding to each time point is calculated, the trajectory guide variable coefficient corresponding to each time point is subjected to analysis and extension to generate a processed trajectory guide variable coefficient; and according to attributes of data read from the template control file, a data source code file which can be identified by high-level languages is generated. The conversion method is capable of achieving autonomous analysis and processing of the control data and rapidly and reliably converting the control data text file to the high-level language data source code file which can be identified by rocket flight control software.

Description

technical field [0001] The invention relates to an aircraft control data conversion method, which is used for automatically extracting and processing the content of the control data text file and converting it into a high-level language data source code file. Background technique [0002] With the in-depth development of my country's manned spaceflight projects, higher requirements have been put forward for the accuracy of launch vehicles, especially in recent years, the introduction of control system redundancy technology and iterative guidance methods has greatly increased the amount of launch vehicle flight control data. Increase. In order to meet the requirements of high-precision orbital entry for rendezvous and docking missions, the launch vehicle system cannot determine the final orbital parameters, aiming parameters, and wind correction parameters until 4 hours before launch. Since the flight control data of the launch vehicle directly determine the orbital parameters...

Problems solved by technology

For example, before launching a tactical missile, the control data that needs to be bound is converted into a binary format and then directly uploaded to the flight control computer for use. Although this method is simple and feasible, it is highly coupled with the flight control software and compiler. Address mismatches can be disastrous

Another example is that a certain strategic missile guidance program (including data) generation system can quickly calculate the binding data after obtaining the target state, replacing the original manual calculation, which greatly enhances the response speed of strategic missiles, but the system is mainly for binding data Computational problems, and only supports assembly language-oriented applications and specific application objects, does not have the ability to extract and analyze data, cannot realize data conversion to high-level languages, and has poor scalability
