摘　　要：为了获取和研究全光纤电流互感器(OCT)挂网试运行的准确参数和真实性能,介绍了1种基于GPS授时模块的OCT远程实时同步监测系统。由于OCT光源光强不稳定,增加了光源光强信息的采集;利用GPS模块的PPS脉冲和授时,实现异地同步采集;通过AMR11芯片控制数据采集、GPS授时和远程通信,实现单CPU结构的SPMU功能。该系统具有结构简单,价格低廉,方便扩展等特点;同时系统在监测的实时性和精确性上有良好表现,达到了设计初衷。In order to obtain the accurate parameters and real performances of the fiber optic current transformer（OCT） in tentative operation,a real-time synchronization remote monitoring system is developed,which is based on the GPS timing module.Information of the light source intensity is collected to compensate the performance degradation induced by the intensity instability;the PPS pulses of the GPS module and GPS timing are used to achieve off-site synchronous acquisition;AMR11 is used to control data acquisition,GPS timing and remote communication as a single-CPU structure of SPMU.The system is characterized by simple structure,low cost,easy expansion,etc;At the same time,the system real-time performance and accuracy of the system are good,meeting the design requirements.
