| 摘 要： | 以Philips公司的ARM7TDMI处理器LPC2214为核心,设计并实现了一种应用于某航空飞控系统中的容量为128 MB的飞控系统数据记录器.该记录器是一种用于记录飞控系统状态的机载设备,其目的是为了日后分析飞控系统的工作情况.实际使用表明,该记录器设计方案可行,且与传统的数据记录器相比,高达128 MB的容量,使得使用RS-422连续记录数据的时间大幅提高,使用USB接口,则突破了以往数据记录器使用串口上传数据速度慢的限制,大大缩短了传输时间.

| Abstract: | A kind of design and application for a flight control system data recorder based on LPC2214 is introduced.It is used for recording the relevant data of the flight control system in aeroplane,the purpose is to analyze the working state of the flight control system in laboratory.It is indicated through practical application that its design scheme is feasible.Compared with the traditional data recorder,its 128 MB memory makes the time of the recording through RS-422 increase greatly,and unlike the COM port,using USB interface can decrease the transmitting time greatly. |
