摘要
震源同步系统产生的验证时断信号是一种重要的辅助道数据,用于辨识震源激发与数据采集是否同步。本文对验证时断信号落后于钟时断信号的原因进行了分析,测试了电路的总延迟量和分段延迟量。阐述了提高震源同步系统的同步精度,保证验证时断信号对同步辨识准确性的方法。
The confirmation time-break signal produced by synchronous system of source is important auxiliary channel data that is used to identify the synchronization between the source shooting and data acquisition. The paper analyzed the reason of the confirmation time-break signal lagging behind the clock time-break signal, measured the total delay times and section delay times of circuit and expounded the methods for improving the synchronous precision of synchronous system of source to guarantee the identified correctness of synchronization by using confirmation timebreak signal.
