【摘要】：随着计算机科学技术的发展,软件系统随之变得异常复杂和庞大,作为软件生命线的软件质量,便成为人们最为关注的焦点。于是,软件质量及其可靠性就成为当今软件设计和软件开发领域中最为关键的问题。目前主要有两种保证软件可靠性的方式:软件可靠性设计和软件可靠性测试。本文以GNSS全系统仿真软件平台课题为研究对象,研究如何保证和提高它的可靠性,分析出适合GNSS全系统仿真软件平台的可靠性设计方法和测试模型,由此设计出对应的可靠性测试工具,具体内容如下:1.论文详细描述了GNSS全系统仿真软件的特点,并在此基础上提炼出GNSS全系统仿真软件的测试需求和测试指标。2.设计增强GNSS全系统仿真软件可靠性的设计方法,这就包括软件功能故障检测、软件死循环处理检测以及软件运行处理中,数据检测的设计,设计被测对象的测试方案。3.设计GNSS仿真软件可靠性测试的测试软件工具的系统框架,提出设计思路,这就包括测试工具的总体设计、结构框架、系统介绍等。4.GNSS仿真软件测试工具的具体设计实现,主要是对设计测试模型,测试系统的各个子模块,整合各模块的可靠性,总体分析系统可靠性。GNSS软件可靠性测试工具的具体实现为:根据GNSS仿真软件的特点,首先设计出适合被测对象的可靠性测试流程。其次将被测软件从功能模块分为地面主控站、空间星座、用户接收机以及主控站-空间星座和空间星座-用户接收机两个通信模块进行可靠性设计与测试,这就包括对各模块的功能可靠性、信号可靠性、通信时间可靠性以及软件无故障运行时间的设计与测试,在这之前,根据模块的重要性,设计出剖面模型分配各模块的可靠性比例。最后分析测试结果,拟合多次测试数据,直观评估GNSS仿真软件可靠性。5.总结全文工作,包括本次论文工作总结以为未来工作展望。
[Abstract]:With the development of computer science and technology, software system has become extremely complex and huge. As a lifeline of software, software quality has become the focus of most attention. The quality and reliability of software has become the most critical problem in the field of software design and development. There are two main ways to ensure the reliability of software:. Software reliability design and software reliability testing. This paper takes the GNSS full-system simulation software platform as the research object. This paper studies how to ensure and improve its reliability, and analyzes the reliability design method and test model suitable for GNSS system simulation software platform, and designs the corresponding reliability testing tools. The main contents are as follows: 1. The characteristics of GNSS simulation software are described in detail. On this basis, the test requirements and test index of GNSS full-system simulation software are extracted. 2. The design method of enhancing the reliability of GNSS full-system simulation software is designed, which includes software function fault detection. The design of data detection in software dead-loop processing and software operation processing, and the design of testing scheme of the object under test. 3. The system framework of GNSS simulation software reliability testing tool is designed. Put forward the design ideas, including the overall design of the test tool, structure framework, system introduction and so on. 4. GNSS simulation software test tool design and implementation, mainly on the design and test model. Each sub-module of the test system integrates the reliability of each module. The overall reliability of the system. GNSS software reliability testing tools are realized as follows: according to the characteristics of GNSS simulation software. Firstly, the reliability test flow is designed for the object under test. Secondly, the software is divided into ground control station and space constellation from the function module. The reliability design and test of the user receiver and the main control station-space constellation and space constellation-user receiver include the functional reliability and signal reliability of each module. Before the design and test of communication time reliability and software failure free running time, according to the importance of the module, the section model is designed to allocate the reliability ratio of each module. Finally, the test results are analyzed. Fitting the test data for many times and evaluating the reliability of GNSS simulation software intuitively. 5. Summarize the full text work, including the work of this paper as the future work prospect.
