近几年 ,ELIN车站电台频繁出现无接收故障 ,平均每年 30次以上。故障发生时 ,电台有时可自动恢复 ,有时需开关电源后恢复 ,故障的出现具有随机性 ,很难跟踪采样。经一年多的攻关 ,取得一定成果 ,现介绍如下。1　判断故障流程图为方便维修人员处理故障 ,总结出判断故障的流程图 In recent years, frequent ELIN station radio reception failure, an average of more than 30 times per year. When the fault occurs, the radio can sometimes recover automatically, and sometimes need to switch power supply recovery, the emergence of the fault has a random nature, it is difficult to track the sampling. After more than a year’s research and achieved some results, are as follows. 1 to determine the fault flow chart for the convenience of maintenance personnel to deal with failure, summed up the flow chart to determine the fault
