移频自动站间闭塞联系电路设计

Design of Connection Circuit Between Station for Frequency-Shift Automatic Block

自动闭塞区段需设计自动站间闭塞时，依据区间移频轨道电路集中区的划分方式，介绍了两种站间联系电路的设计方案及各自的工作原理，同时在功能、投资及适用方面进行了比选。

As designing automatic block for the automatic block sections, the design scheme and operation principle of two connection circuits between stations are presented according to the way to divide zones of the section frequency-shift track circuits, and also their functionality and investment are compared.
