摘　　要：在地震勘探中,激发系统和采集系统的同步控制是一个非常重要的问题。通常可以利用卫星信号进行设备内部硬件之间的时钟同步,但不同硬件模块之间存在同步误差累积,利用时间TB脉冲信号对各系统进行同步,既可以避免同步误差的累计,也具有响应及时的优点。本文针对地震激发设备可控震源电子控制系统的内部同步控制、激发控制系统与采集系统有线仪器之间的同步控制、以及激发系统与采集系统节点仪器之间的同步控制应用问题进行了简要的阐述。The synchronous control of excitation and acquisition system is a very important issue in seismic exploration using seismic instruments.Usually,satellite signals can be used for internal hardware clock synchronization within devices,but there is an accumulation of synchronization errors between different hardware modules.Using TB pulse signals to synchronize various systems can not only avoid the accumulation of synchronization errors,but also have the advantage of timely response.This article briefly elaborates on the internal synchronization control of the seismic excitation equipment vibrator control system,the synchronization control between the excitation control system and the wired instruments of the acquisition system,and the synchronization control application between the excitation system and the node instruments of the acquisition system.
