| 摘 要： | 国产某型飞机在持续适航阶段开展事件收集、风险评估、工程调查和措施制定等工作时,需要机型资料、机队信息、运营记录、事故事件、局方信息等工程数据提供输入、参考以及辅助分析。研究了持续适航工程数据与大数据之间的关系,初步规划了面向持续适航工程数据的大数据系统架构,并通过以下自动化方式实现了相关数据的采集与处理,形成了持续适航工程数据库:首先利用网络爬虫数据采集技术实时准确地获取一些国内外公开数据;其次应用VBA语言对已获得数据进行整理与自定义处理;最后基于大数据的映射分析方法对这些工程数据进行分析。该持续适航工程数据库已有效应用于某型国产飞机持续适航体系的日常运行工作。

| Abstract: | When an aircraft in continuous airworthiness phase, the airplane maker needs to do the work of event collection, risk assessment, engineering survey and measure establishment, and then needs plenty of engineering data provided as input information, reference, also can provide the auxiliary analysis, these engineering data such as model data, fleet information, operation records, accident and events, and Airworthiness Directive. This paper studies the relationship between the continued airworthiness engineering data and Big Data, preliminary planning for the continued airworthiness engineering data system structure based on Big Data concept, and through the following automated way to realize the data acquisition and processing,to form the continuous airworthiness engineering database: first of all, using web crawler data acquisition technology to accurately obtain some public data. Secondly, the data is collected and processed by VBA language. Finally, analyzes the engineering data based on the mapping analysis method. The continuous airworthiness engineering database has been used for the daily operation of the continuous airworthiness system. |
