基于经验模态分解的发动机脉动压力数据分析

在机载测试技术中，机载数据总线数据量急剧增加，数据处理越来越趋于复杂化，软件可复用性的要求越来越高。为满足这些需求，将抽象工厂模式的思想应用到航空总线数据处理中，根据抽象工厂的特点和适用场景，将总线数据按照类型进行实例化，形成对外统一的接口，然后对不同的总线接口进行数据处理。该接口只与总线的协议标准和技术特点有关，不依赖于具体信号，因此实现了数据处理的通用化，突破了原来面向各个接口信号分别处理的思想，从而实现了软件可复用的要求，提高了机载总线数据处理的效率和可靠性。

Analysis of engine fluctuating pressure data based on empirical mode decomposition

In the field of airborne test technology, the data amount of airborne data bus is increasing rapidly, the data processing method becomes more and more complex, and the requirement for software reusability is getting higher and higher. To meet these requirements, we introduce abstract factory design pattern to the field of aviation bus data processing. Based on the characteristics and application scenarios of this design pattern, we instantiate data bus by types to form a unified interface to users. Then we perform data processing on different bus interfaces. For the interface is only related to the protocol standards and technical characteristics of the bus, and independent of specific signals, it realizes the generalization of data processing method, and avoids processing each interface signal separately. So, it meets the requirements of software reusability and improves the efficiency and reliability of data processing for airborne bus.
