摘　　要：针对带有中间出岔的股道闭环电码化电路,存在当办理至该股道的下行(上行)接车进路,列车顺序占用各区段,经机车摘挂作业后,再次办理该股道的上行(下行)发车进路时,中间出岔股道的3个区段的QMJ无法正常励磁,造成发码通道被切断,机车信号收不到码的问题,提出可行的电路修改方案予以解决。For the closed-loop coded circuit of the tracks with middle switch,the trains occupy each section sequentially when a downward or upward route reaching the track is handled.After the pick-up and drop operations of the locomotive,the QMJ of three sections in the middle switch may fail to be energized when the downward or upward route reaching the track is handled again,the middle much amiss track of not normal excitation,resulting in the cut-off of code sending channel and cab signal not receiving codes.A feasible circuit revision solution was proposed too address the problem.
