Design And Implementation Of Signal Generation And Measurement Software For Missile Ground Automatic Test System

The development of missile has always played an important role in the field of national defense.The test of missile before launch is an important guarantee for successful launch and accurate hit target.Over the years,a large number of funds have been invested in the research of missile test field.The missile ground automatic test system has developed from the special type system to the universal type system,and each country has put forward higher standards and requirements for missile test.In recent years,high performance and small volume bus test equipment are constantly appearing,which greatly improves the performance of missile test system.However,the performance of missile ground automatic test system not only depends on the support of the hardware platform,but also needs to match the test software with the hardware system.Therefore,Designing more advanced and perfect missile ground automatic test system software has become the key research direction in the field of missile test.Based on the above background,this paper develops a software platform for signal generation and measurement of the missile ground automatic test system for the purpose of improving the universality of the software and the interchangeability of the instruments.In the process of software platform development,we mainly adopt the advanced signal-oriented design idea to research and apply the related standards and technologies of signal-oriented,and improve the versatility of software by dynamically matching instruments in the form of signals.The missile ground automatic test system is analyzed,the overall design scheme of the system is determined,the hardware platform of the system is built,and the functional modules of the software are divided.According to IEEE1641 standard,an unambiguous and perfect method is designed to describe signals,including static text description and dynamic interface description.The system resource management module was developed,and the description methods of test items,test instruments and test stations were designed respectively in combination with IEEE1671 and its sub-standards to realize resource sharing among different systems.At the same time,resource modeling tools were developed to assist users to configure and generate resource description documents.The test resource matching module is developed to match the signal demand with the instrument capability port in the form of signal,and the test signal demand is separated from the specific test instrument in the way of dynamic matching.By using IVI-SIGNAL driver technology,the instrument driver function is twice encapsulated and encapsulated into COM component to provide a unified interface to the external function,and the specific realization of the voltage and current source module and the digital multi-meter module IVI-SIGNAL driver component is given.Design the component interface interaction between the signal library management module,the test resource matching module and the instrument driver module,and complete the development of the core part of the software.The design experiment verifies the function of the missile ground automatic test system software to generate excitation and measurement signals,and verifies the interchangeable function of different instrument types which have the same signal capability.
