一种大容量固态飞行数据记录器设计

摘要

A Large-capacity solid-state flight data recorder is designed with ATmega 128 as mierocontroller core and Erasable, nonvolatile Flash Chip as storage medium.This paper introduces the hardware system design, the realization of some functions and related software design process.This design has been a successful application of aircraft flight control experiment, a complete record of the flight related to the experimental data.%为实时记录飞行器飞控试验中飞控计算机输出的试验参数.设计了一种以Atmega128单片机为核心,可擦除的非易失性的FLASH芯片作为数据存储介质的大容理数据记录器;采用RS-422接口与外部设备进行实时通讯,并在每架次飞行实验完成后,可通过USB2.0实现数据高速读取;文中介绍了系统设计的硬件组成,各部分功能实现以及相关软件设计流程,本设计已在某飞行器飞控实验成功应用,完整记录了飞行过程中相关的实验数据.
