New Data Recording System Applied to Unmanned Aerial Vehicle

无人机在实际应用中,呈现出采集数据量大、多传感器数据同步要求高、数据分析日益重要等特点。本文提出的新体系数据记录系统,针对当前无人机应用场景特点,能够实现多源数据的高速同步记录,且具备一定的数据分析能力,具有广阔的应用前景。该数据记录系统基于当前主流的VITA46串行数据架构标准,系统主要包括数据记录平台、数据转存平台、数据分析平台和数据管理平台,各平台之间及平台内部各模块之间,采用高速串行交换总线互连,有效解决了GB/s级别带宽的数据传输问题。此外,通过把各平台进行系统集成,单机设备即可实现高速数据采集、存储、实时显示、数据回放和应用分析等多种功能,适用于农业、电力、勘探和测绘等多场景应用下的无人机数据采集、记录与分析。

With the increasing innovation of UAV technology in practical applications,it presents features such as large amount of collected data,high synchronization requirements for multi-sensor data,and increasingly important data analysis. The data recording system under the new system proposed aiming at the new characteristics could achieve high-speed synchronous record of multi-source data, and had certain data analysis capabilities ,with broad application prospects. The new data recording system was a high-performance solution of integrated data acquisition,storage and analysis based on the eurren｜ mainstream VITA46 serial data architecture standard. The system mainly includes a data recording platform,a data transfer platfoml,a data analysis platform,and data management platform. High-speed serial interaction was used between platforms and modules inside each platform , such as main control module,signal process- ing module, signal acquisition module ,data storage module ,passive backplane, and serial data interaction module. The bus intereonneetion eft）etively solved the data transmission problem of GB/s bandwidth. In addition,through the system inte-gration of each platform, a single device could achieve high-speed data acquisition ,storage ,realtime display,data play back and application analysis and other functions,applicable to UAV＇s data acquisition,recording and anlysis in many scenarios such as agriculture, electricity, exploration and surveying, etc.
