一种飞行参数防护记录装置的设计

Design of a Protective Recorder for Flight Data

针对现有的飞参防护记录器不适用于记录大容量飞行参数的问题,设计了一种新型防护记录装置。该装置不仅通过以太网通信总线来连接飞参采集器,可以快速、准确地接收采集器发送的飞行参数,还通过设计掉电储能、备份存储和快捷卸载等功能,全面提升了装置的性能。工程应用实践表明:该装置安全可靠,记录飞参数据的容量和精度都比较高,数据卸载方便,可以为飞参数据的分析与研究工作提供客观数据。

In view of the problem that the existing flight data protective recorder is not suitable for recording high-capacity flight data, a new type of protective recording device is designed. This device not only connects the flight data collector by the Ethernet communication bus so as to quickly and accurately receive the flight data sent by the collector, but also improves the performance of the device through functions of power-off energy storage, backup storage and quick unloading. The practice shows that the device is safe and reliable, which has the high capacity and precision of recording the flight data, and being convenient of data unloading. It can provide objective data for the analysis and research work of the flight data.
