A data simulation method

Abstract

The invention provides a data simulation method and relates to software design technology. The method includes step 1, extracting signal field information from the header file data interface, and storing it in a header file that can be recognized by a compiler; step 2, storing the signal field information in the header file into an XML file, according to the XML The variable values ​​stored in the file initialize the field variables in the signal field information; Step 3, modify the field variable values ​​in the XML file to perform data simulation. The invention can easily read and write the simulation data to the XML file, and can be used in the development of simulation software and monitoring software. The method for extracting the simulation signal field information from the data interface of the header file proposed by the invention can solve the problem that the interface control file needs to be checked manually when the interface in the interface control file database is inconsistent with the interface in the actual airborne code. Using code generation technology, a standard and unified programming style can also be achieved.

Description

Technical field [0001] The present invention belongs to the field of computer software design, and specific relates to a data simulation method. Background technique [0002] Interface Control Document (ICD, Interface Control Document is the top-level file design of the avionics system, which is the basis for the initialization of interface simulation software. ICD defines a variety of electrical electronic interfaces, signals, messages, and data streams to be handled and managed by the avocation system and subsystems. The overall design unit is written during the detailed design process of the system. It is the detailed design of the avionics, code writing, procedure The important basis for research and development work such as test and functional joint test, running through the development of avionics software. The header file is one of the components of the software program. The data interface is an important component of the software header file. You need to write according t...

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
