改进Macha系统实现不同类型采集系统同步接收地震数据

Improving MACHA system to realize synchronous receiving seismic data for different kind of data acquisition system.

Macha系统是世界上最先进的震源同步系统之一。文中以Macha系统和SN388地震仪及JYD-15A测井仪的联机为例,介绍了Macha编码器由Master(主控制方式)改为Slave(从控制方式)以及由Slave方式恢复为Master方式的方法。实现多台仪器或不同类型的仪器之间的同步,为新开发的井间地震技术提供了有力的设备保障。

MACHA system is one of the most advanced seismic source synchronous system. Taking the application of matching MACHA system with SN388 seismograph and JYD-15A logging device as an example, the paper introduced the method that converts the MACHA encoder from MASTER control state to SLAVE one and its inverse process, realizing synchronism between multiple instruments and between different kind of instruments and providing powerful equipment support for new-developed cross-hole seismic technology.
