【摘要】 地震勘测中经常需要多种震源施工,为了解决SN388仪器与空气枪的同步问题而做了这个接口电路图,利用单稳态电路的延时特性,去除了影响正常同步触发的干扰脉冲,实现了系统的同步,满足了生产需求。更多还原

【Abstract】 Various epicentre implementing are always needed in the seismic prospecting. In order to solve the synchronous problems between SN388 and air-gun,the interface circuit diagram are charted,which has taken the advantage of delay characteristics of mono-stable circuit to eliminate the disturbance pulse which has influenced normal synchronous triggering,and has achieved systematic synchronization and satisfied the need of seismic prospecting.更多还原
