Construction Of Universal Development Platform For Test Software Of Air Data Computer Automatic Test System

At present,universality of automatic test system becomes the main research oriention of automatic test system.The research of software technology's universality of automatic test system has been paid more and more attentions and has been studied extensively in the field of automatic test system.As a significant comprehensive measuring equipment among the airborne electronic equipments,the aircraft maintenance enterprise paid attentions to the research of Air Data Computer(ADC)'s universal test software.This thesis is mainly to construct a set of universal development platform of test software for ADC automatic test system and study the realization method of test software's universality,besides,a software development platform has been built which can satisfied the automatic test of performance of various ADC types.This thesis introduces the background of the subject firstly,and lays out demand and necessity of universal platform development of ADC test software.Then a generation method of automatic test program based on Accesss database and Lab VIEW operation mode of data flow is proposed,which divides the ADC universal development platform into three parts:test information modeling,test program function library and test program execution.According to the test file generated in the test information modeling by user, The execution of ADC test program is accomplished by organizing and calling test function in the test function library dynamically which can be run directly without the compiler.This method can reduce the user requirements on the programming ability.This thesis designs Test Information Modeling System(TIMS) and Test Program Running System(TPRS) of development platform by using Visual C++ and Lab VIEW.At Last,This thesis applies the ADC universal development platform of test software to the automatic test program generation of a certain type of ADC,and proves the rightness of test result.By developing ADC automatic test program of different types,ADC universal development platform of test software can meet the requirements of automatic test of different ADC types,and realize requirements of the universality of test software for the factory.
