The invention discloses a comprehensive detection train clock synchronization network test method and device, and relates to the technical field of communication, and the method comprises the steps: determining an output moment when a standard signal source outputs a test signal, the standard signal source being used for generating a test signal for testing the operation of a comprehensive detection train in real time; receiving timing clock information sent by the master clock equipment; marking a timestamp for the test signal according to the timing clock information; calculating a difference value between an output moment when the standard signal source outputs the test signal and a test signal marking timestamp to obtain a clock offset; and analyzing the clock offset to obtain a test result for comprehensively detecting the train clock synchronization network. According to the method, in the precision test process of comprehensively detecting the train clock synchronization network system, the error of the test signal output moment and the clock error of data processing of the system are considered, and an accurate clock synchronization precision test result is obtained.

    本发明公开了一种综合检测列车时钟同步网络测试方法及装置,涉及通信技术领域,其中该方法包括:确定标准信号源输出测试信号的输出时刻,标准信号源用于实时生成对综合检测列车运行进行测试的测试信号;接收主时钟设备发送的定时时钟信息;根据定时时钟信息,为测试信号标记时间戳;计算标准信号源输出测试信号的输出时刻与测试信号标记时间戳的差值,得到时钟偏移量;对时钟偏移量进行分析,得到综合检测列车时钟同步网络测试结果。本发明可以在综合检测列车时钟同步网络系统的精度测试过程中,考虑测试信号输出时刻的误差和系统进行数据处理的时钟误差,得到准确的时钟同步精度测试结果。
