A data simulation method

Abstract

The invention provides a data simulation method, which relates to a software design technique. The method comprises the following steps of: extracting signal field information from a header file datainterface and storing the information in a header file that can be identified by a compiler; 2, storing the signal field information in the header file in an XML file, and initializing the field variable in the signal field information according to the variable value stored in the XML file; 3, modifying the variable value of the field in the XML file to carry out data simulation. The invention canread and write the simulation data of the XML file very easily, and can be used for the development of the simulation software and the monitoring software. The method for extracting the simulation signal field information from the header file data interface provided by the invention can solve the problem that the interface control file database needs to manually check the interface control file when the interface is inconsistent with the actual airborne code. The method uses code generation technology and thus achieves a standard uniform programming style.

Description

technical field [0001] The invention belongs to the field of computer software design, in particular to a data simulation method. Background technique [0002] Interface Control Document (ICD, Interface Control Document) is the top-level file of avionics system design and the basis of interface simulation software initialization. The ICD defines various electrical and electronic interfaces, signals, messages and data flows to be processed and managed by the avionics system and subsystem. It is written by the overall design unit in the detailed design process of the system. The important basis for R&D work such as testing and functional joint testing runs through the R&D process of avionics software. The header file is one of the constituent files of the software program. The data interface is an important component of the software header file, which needs to be written according to the program coding requirements. The data interface of the software header file must be organ...

AI Technical Summary

Problems solved by technology

In the development process of the actual model avionics system, the interface control documents or related databases are often not updated in time, which makes the generated interface documents inconsistent with the airborne model, resulting in simulation data errors
