摘要
提出了基于GPS授时的同步数据采集系统改进方法。该方法预置采集开始时刻,利用GPS授时检测所产生的触发信号,用于同步各异地分布的数据采集装置。理论分析和仿真实验结果表明,上述方法可以达到微秒级的时间同步。
This paper comes up with an improved solution of the synchronous acquisition systems. GPS timing set up starting acquisition time in advance and generate trigger signals when the devices with GPS timing detect that time comes, then it can be used to synchronize distributed data acquisition devices. Theoretical analysis and simulation results show that this method can reach microsecond level of time synchronization.
