摘要
针对传统测试序列建模方法未能实现模型规范化,对判读知识、测试流程控制的表达难以直接驱动测试系统研制的问题,提出一种基于可扩展标记语言遥测遥控信息交换(XTCE)标准的测试序列建模方法。引入“知识元数据”和“事件元数据”概念,将XTCE标准描述对象的范围,从先前遥测参数、遥控指令,扩展覆盖至判读知识,顺序、循环及条件等测试流程控制,以此为基础设计符合XTCE标准的测试序列Schema。工程实践结果表明:该方法输出的模型,可有效驱动测试序列执行、综合数据判读、载荷状态监视等测试软件的灵活重构,实现测试系统对不同测试需求的快速响应。
Aiming at the problem that traditional test sequence modeling method cannot realize the model standardization,and the expression of interpretation knowledge and test flow control is difficult to directly drive the development of test system,a test sequence modeling method based on extensible markup language telemetry and command information exchange(XTCE)standard is proposed.The concepts of“knowledge metadata”and“event metadata”are introduced to expand the scope of the description object of XTCE standard from the previous telemetry parameters and commands to the interpretation knowledge,sequence,cycle and condition test flow control.Based on this,the test sequence schema conforming to XTCE standard is designed.The engineering practice results show that the output model of this method can effectively drive the flexible reconstruction of test software such as test sequence execution,comprehensive data interpretation and load state monitoring,and fulfill the rapid response of the test system to different test requirements.
