摘　　要：主要研制了一种基于小型铷原子频标的数字化多功能时统设备,简单介绍了设计方案,并对性能进行了测试。结果表明,该时统设备能够接收处理北斗/GNSS导航接收机的信号,可用以太网、RS422串口以及本地按键和上位机通信,可用1 PPS/IRIG-B(DC)码2种方式校时,1 PPS/IRIG-B(DC)码/10 MHz 3种方式校频,校频精度能够达到E-12量级,可通过1 PPS/TOD/IRIG-B(DC)码3种方式对下位机授时,授时精度小于10 ns。A digital muhifunctional timing system based on smart rubidium frequency standard is presented in this paper. The digital scheme is provided briefly and the correlated performance is tested. The experimental results indicate that the timing system can receive and dispose time signals from Beidou/GNSS navigation receiver and cali brate time with 1 PPS/IRIG-B （DC） code, calibrate frequency with 1 PPS/IRIG-B （DC） code/10MHz through Eth ernet, RS422 serial port and local keys. The accuracy of frequency calibration can reach E-12 level, supply 1 PPS/UTC code/IRIG-B（DC） code three ways for timing, and the accuracy is less than 10 ns.
