摘要
随着北斗卫星导航系统的不断完善,可以为用户提供更高精度的导航与授时服务,实时的信息采集存储及状态监测成为急需解决的问题之一。设计一种基于BDS的数据采集存储及状态监测系统,选用FPGA作为核心处理器,并详细介绍了实时采集存储的设计与实现方案,同时通过串行通信技术将数据上传到上位机中处理。试验结果表明,该系统具有稳定性高、实时性强和易操作的性能,为导航定位服务中的信息采集监测提供了一种方法,具有一定的工程应用价值。
With the improvement of BeiDou Navigation Satellite System(BDS),it can provide users with more accuratenavigation and timing services.Meanwhile,real?time information acquisition,storage and condition monitoring become the ur?gent problems to be resolved.Therefore,a data acquisition,storage and condition monitoring system based on BDS was de?signed,in which FPGA is selected as its core processor.The designed and implementation scheme of real?time acquisition andstorage is elaborated.The serial communication technology is adopted to upload the data to the PC for processing.The experimen?tal results show that the system has high stability,strong real?time performance and is easy to operate,which provides a methodfor information acquisition and monitoring in navigation and positioning services,and has a certain engineering application value.
