【摘要】 本文主要针对System Four地震数据采集系统的地面设备在使用过程中经常出现的排列不稳定的问题进行了深入分析,如经常掉排列、本道接触不好、漏电等等。找出了造成排列不稳定的主要原因——数传保护电路设计不完善。总结出通过硬件HEPP升级的方法能大大改善排列不稳定的现象,并阐述了其主要内容和电路保护原理。更多还原

【Abstract】 Mainly facing the unstable issue of spread,which usually appears in usage process of surface equipment of System Four seismic data acquisition system,such as often breaking off spread,bad channel contacting and leakage etc,the paper carried out deep analysis and found out the main reason resulting in unstable spread: incomplete design of digital-transmitting protection circuit,summarized that great improvement of the unstable issue of spread can be achieved by upgrading the HEPP hardware,and expounded the main contents and circuit protection principle at the same time.更多还原
