本标准定义了基于复杂虚拟仪器（CVIs）构建家电测试软件系统的框架，CVIs用于处理和显示来自智能传感器的传感器数据和相关元数据。该框架为基于CVI的开发过程提供了指导，其中CVI结构设计包括传感器数据和元数据的管理、基于设备测试环境和测试信息描述的虚拟仪器引擎、测试数据的数据格式以及用于CVI交互的表示性状态转移（REST）服务接口；CVI映射方案描述了从测试单元到CVI的对应关系；CVI关系定义了CVI之间的关系，并描述了扩展和合成多个CVI的方法

This standard defines the framework of building household appliance test software system based on complex virtual instruments (CVIs) which are used for processing and displaying the sensor data from intelligent sensors and the related metadata. This framework provides the guidelines for CVI-based development process, in which CVI structure design covers management of sensor data and metadata, virtual instrument engine based on description of appliance testing ambient and test information, data formats of test data, and Representational State Transfer (REST ) service interfaces for CVI interactions; CVI mapping schemes describe the correspondence from test units to CVIs; CVI relations define the relationships between CVIs and describe the methods of extending and compositing multiple CVIs.
