摘　　要：X-Plane内置的数据采集系统以及基于其"DATA"协议的二次开发,可以提供包括飞行器经度、纬度、平均海拔高度等在内的通用数据,但无法输出诸如仪表着陆系统(ILS)偏移、陆基增强系统(GBAS)偏移等专业性很强的非通用数据。基于X-Plane的"RREF"和"DREF"数据交互协议,利用Python开发了飞行数据交互与分析系统,除通用数据外,该系统还可以根据需要实时采集并存储X-Plane中专业性很强的非通用数据,并能够对采集数据进行分析和回放。模拟飞行数据验证表明,设计的系统能以规定的精度采集所需飞行数据,为实时采集、存储、分析及回放X-Plane中的飞行数据尤其是专业性很强的非通用数据提供了一种有效的解决方案。The general data including longitude,latitude and mean height above sea level of the aircraft can be provided by the build-in data collection system of X-Plane and the secondary development based on its "DATA" protocol,but the non-general specialized data,for example,the deviation of the instrument landing system(ILS) and the deviation of the groundbased augmentation system(GBAS)cannot be output. A flight data interaction and analysis system is developed with Python on the basis of the data interaction protocols "RREF" and "DREF" based on X-Plane. In addition to the general data,the nongeneral specialized data in the X-Plane can be collected and stored in real time as needed by this system,and the collected data can be analyzed and played back. The verification of simulated flight data shows that the required flight data can be collected by the designed system according to specified precision. Therefore,the system can provide an effective solution for real-time collection,storage,analysis and playback of flight data in X-Plane,especially the highly specialized non-general data.
