摘要 在轨道区段中,存在一种室外有分割而联锁按一个区段处理的特殊情况。如分割的轨道区段也需要电码化时,按常规设计预叠加电码化会造成机车信号不能连续收到移频信息。为此,分别分析了25Hz相敏轨道电路配套二元二位继电器和微电子接收器出现该故障的原因,提出对应解决措施,并从施工难度、投资高低、适用性方面进行比较,对其他类似情况具有参考意义。 There is a special case of the coding system in which the track section is composed of two section cuts while it is still regarded as one section in the indoor interlocking system. When the cut track section is also required to be coded, the cab signal system cannot receive freque shift signal continuously if the overlapped code is designed as routine. Therefore, the reasons ncy why such a malfunction occurs to 25Hz phase-sensitive track circuits with two-element two position relay or microelectronic receptor are analyzed. Two corresponding solutions are proposed. We proposed two schemes and compare them in term of difficulty of construction, investment budg et, and applicability.
