摘　　要：介绍了接收机授时接口的工作原理,提出了一种基于模拟工作场景的接收机授时接口新型测试方法,通过设计程控IRIG⁃B时间码发生器模拟产生异常时码,测试了接收机授时接口的容错性,并以长期授时测试场景用例检验了接收机授时接口工作稳定性,解决了实验室条件下接收机数据时间戳乱序、长期工作中时间戳跳变以及接收机授时信号异常控制等授时接口测试的难题。The timing interface working principle of the receiver is introduced,and a new test method based on the simulation work scene with respect to the receiver is proposed in this paper.The fault tolerance and working stability about the timing interface of the receiver has been tested through the designed program⁃controlled IRIG⁃B time code generator which is used to simulate the abnormal time code and a long⁃term timing test scenario.Thus,Via the method,the problems of timing interface testing in laboratory condition including the disorder of data time stamp,the time stamp jumping on long⁃term operation and the abnormal control of the time service signal is solved.
