摘要
G3i仪器是Inova公司推出的新一代有线遥测地震仪器,其地面设备采用了集中供电和多数据传输路径方法。本文对G3i仪器中的采集站的多路径传输原理、数据包编码方式以及具体的实现方法进行了详细的阐述。G3i仪器中的采集站通过采用8B/10B编码技术,使传输的数据达到了直流平衡,降低了误码率,同时采用了FPGA的时钟恢复技术,达到了更加稳定的效果,具有与其它仪器不同的特性。
G3i system is a new generation of cable telemetry seismic instruments produced by INOVA Company,its ground equipment adopts centralized power supply and multi-path data transmission.The paper introduces the data transmission principle,data encoding and concrete implementation method of G3i instrument's RAM in detail.The applications of 8B/10 Bencoding make the DC balance of transmission data and reduce the error rate.Using the clock recovery technology of FPGA,it shows more stable.From the practical application,its transmission performance is stable and reliable,and has the excellent properties.
