Development Of Space Time Consistency Service Software For Joint Test Platform

With the development of information weapon equipment,joint test has become the main research direction of weapon equipment test method.The test and test research team of Harbin Institute of technology has developed the joint test support platform(H-JTP).At present,H-JTP has been applied in many fields,which can realize the interaction between test resources and test system.The research of space-time consistency can solve the problem of inconsistent expression of time and space of test resources in each node of joint test,which is an important basis for effective joint test.But at present,H-JTP lacks a solution to the space-time consistency of joint test,which affects the application of H-JTP in large-scale joint test.Therefore,aiming at the problem of space-time consistency of joint test system,this project proposes a solution to space-time consistency of joint test system based on H-JTP,and develops a series of space-time consistency service software according to the solution,which lays an important foundation for the application of H-JTP in large-scale joint test operations.This article analyzes the causes of time-space inconsistency in the joint test system,and puts forward a complete solution to the problem of time-space consistency.Aiming at the problem of space inconsistency caused by different coordinate systems in joint test system,the transformation algorithm between common coordinate systems is studied and analyzed.In order to solve the problem of inconsistent time representation,referring to the H-JTP time object model,this paper studies and analyzes the conversion algorithm between time description methods.According to the frequency of data received by adaptive resource equipment,DR algorithm model is used to process and analyze the spatiotemporal information.In order to solve the problem of event causality inconsistency caused by different network transmission delays in joint test system,an event causality consistency method based on directed acyclic graph is proposed.Based on the research of spatiotemporal consistency method,the object-oriented software development method is adopted.According to the idea of software engineering,the coordinate transformation service software,time transformation service software,Dr calculation service software and event processing service software are developed.The requirements of four services software are analyzed respectively,and the structural design of the software is completed.According to the software design,the coding of the series of service software is completed,and the service is called by writing the components in H-JTP,and the series of service software is tested.The test results show that the spacetime consistency series of service software meet the software requirements.Finally,the rationality of the overall scheme is verified by an application case.A mission scenario of missile attacking surface target is designed,and a variety of spacetime inconsistency factors are designed.A verification platform is built by using H-JTP,and the scenario is run.Through the analysis of the results,the rationality of the spacetime consistency solution and the correctness of a series of service software are verified.
