摘　　要：信息处理网络化和工业控制自动化的快速发展,对同一网络系统下设备的时间同步提出了更高的要求。提出了基于北斗卫星导航系统(BDS)与NTP的软硬件混合时间同步设计方案,介绍了其相关原理,并且进行了软硬件的实现。主控板处理器采用国产处理器龙芯1C300B,搭配嵌入式Linux系统部署NTP服务,核心芯片采用国产芯片,整个软硬件设计契合自主国产化思想。经测试,该服务器功耗及成本较低,性价比高,可达到毫秒级时间同步精度,具有较高的应用价值。With the rapid development of information processing network and industrial control automation,higher requirements has been put forward for the time synchronization of equipment under the same network system.A hybrid time synchronization scheme of software and hardware based on BDS and NTP is proposed,and the related principle is introduced,and the hardware and software implementation is carried out.The sever adopts the domestic processor Loongson 1C300B as the main control board processor,with the embedded Linux system to deploy NTP service.Meanwhile,the core chips are all made in china,the whole design corresponds to the thought of independent localization.After testing,the sever has low power consumption,low cost,high cost performance,and can achieve millisecond time synchronization accuracy,which has great application value.
