摘　　要：Sercel公司在FDU2S采集站维修技术方面对国内领域一直未开放,国内维修处在探索阶段。为提升采集站修复率,开展了针对FDU2S采集站主要故障类型的技术研究。首先从分析FDU2S采集站的工作原理入手,根据FDU2S采集站实现的功能,将电路板细分为五大模块,并绘制了采集站工作原理框图,结合TMS428测试系统对采集站的测试项目的选取和测试指标的设置,画出采集站测试原理框图。根据得到的电路原理及信号分析,对电路板加入测试信号,通过追踪信号走向,确定关键元器件型号等手段,绘制了电源电路图、测试电路图。结合维修实例总结了检修与测试流程,最终实现了故障FDU2S采集站的自主检修。Sercel Company has not opened the FDU2S acquisition station maintenance technology to the domestic field.The domestic maintenance is in the exploratory stage.In order to improve maintenance efficiency,research on main fault types has been carried out.Firstly,the working principle of FDU2S acquisition station is analyzed.According to the function of FDU2S acquisition station,the circuit board is classified into five modules,and the working principle block diagram is drawn.Combined with the testing items of the acquisition station by the TMS428 testing system,the testing principle block diagram is also drawn.According to the obtained circuit principle and signal analysis,test signal is added to the circuit board,and the power circuit diagram and test circuit diagram are drawn by means of tracing the direction of the signal and determining the type of the key components.Combined with maintenance examples,the maintenance and testing process is summarized.
