传感器信号接口标准符合性测试研究

摘要

传感器信号接口标准是我国物联网标准体系的重要组成部分,专注于研究实现传感器互换性、互操作性功能所涉及的接口问题；标准定义了数据描述文件作为接口信息的载体,并规定了两种表述格式:XML格式和二进制格式.而标准符合性测试是标准顺利实施和产业化的重要手段；围绕数据描述文件的内容与格式,对信号接口标准的符合性测试方法进行了系统研究:XML格式的测试包括形式测试与有效性测试；二进制格式的测试包括结构测试与枚举测试；在此基础上,设计并实现了相应的测试平台,实验表明,平台可以实现错误查找、错误提示功能,满足符合性测试需求.%The sensor signal interface standard is an important part of the China's standard system of Internet of things and focus on research sensor's interchangeability and interoperability. The standard defines a data description file as a carrier of the interface information and provides for two kinds of representation formats: XML format and binary format. For industrialization of the standard, it is very important to research and construct the conformance testing system. So this paper emphasizes the research of methods of signal interface standard con-formance testing: XML format testing includes form testing and validity testing; Binary testing includes structural testing and enumeration testing. On this basis, the testing platform was designed and completed. Experimental results show that the platform can find and prompt errors of description files, which means that it meets the compliance test requirements.
