特殊站场正线股道过长及道床电阻过低时,正线股道需要人工分割。此时GQMJ的设置及其励磁电路需要进行改进。由于闭环电码化系统采用了各区段同时发码的方式进行闭环检测,对于已经出清的接发车进路,应及时切断向轨道上发送的前方信号机信息,以防后续列车的冒进。因此,需设一套发 Special stations are the main stock channel is too long and the resistance is too low, the main strands need artificial segmentation. At this point GQMJ settings and excitation circuit needs to be improved. As the closed-loop digitalization system uses the method of sending and receiving of all sections at the same time to carry out closed-loop detection, it is necessary to cut off the information of the front signal sent to the track in time to prevent the subsequent train from advancing. Therefore, we need a set of hair
