摘要
用电信息采集终端中的信息数据项数据量庞大、数据项零散、应用组合复杂。针对这些特点,作者们对数据信息进行了整理、归纳和挖掘,将数据项基本分为参数数据、实时数据、历史数据、事件数据、转发数据等类型,并结合对Arm-Linux系统、SQlite3嵌入式数据库等方面的研究,对各类数据进行了封装,并对外提供出统一的存读接口,从而力图打造适用于用电信息采集终端应用的统一的、灵活的、安全的、快速的数据平台。
The whole electric energy data acquisition terminal's data-number is very large and data-items in the terminal are very scattered and those data's application groups are very complex. In view of those characteristics, data in the terminal is defined to configuration-data and real-data and history-data and event-data and forward- data, data's arrangement and classify and mining is researched in the article. With the basic researching and using of Arm-Linux and SQlite3 database, those data's read-write methods is encapsulated and a interface which is smart and safety and fast is defined and given. So a uniform and smart and safety and fast data platform for all kinds of collecting terminals in electric energy data acquire terminal is designed.
