摘　　要：为了满足车载系统各类设备高密度记录数据(尤其是车载视频数据)的存储需求,设计了一种大容量车载数据存储设备,其以x86架构CPU为核心进行外围功能电路扩展,配置了掉电保护功能电路,并选用嵌入式WES2009作为设备的底层操作系统软件。对所研制车载数据存储设备进行试验验证,结果表明其能满足大容量车载数据存储的需求。In order to meet the storage demand of high-density data recording of all kinds of equipments in a vehicle, especially the video streams, a large capacity vehicle-mounted data storage device was developed. The device adopts x86 architecture CPU as the core, and carries out the peripheral function circuit expansion. It configures a power-fail protection function circuit, and selects embedded WES2009 as the operating system software of the device. The data storage device was tested, and the results verified it could meet the requirements of large capacity vehicle-mounted data storage.
