摘　　要：在既有铁路的450 MHz无线列调通信系统改造时,需要同步对传统的数字调度通信系统进行改造。以鹰厦线的数字调度通信系统改造为例,对传统车站FAS交换机方案、共用车站FAS交换机方案、共用备份车站FAS交换机方案等3种方案的优缺点进行比选,推荐采用共用车站FAS交换机方案,极大程度降低了工程投资,同时研究了FAS编号等问题及其解决方案,对其他既有铁路数字调度通信系统改造具有重要参考意义。It is necessary to reconstruct the traditional digital dispatching communication system simultaneously during reconstruction of the 450 MHz wireless train dispatching communication system for the existing line. Taking the digital dispatching communication system for Ying-Xia Line as an example, the paper gives advantage and disadvantage comparison among three solutions of traditional station FAS exchange, shared station FAS exchange and shared backup station FAS exchange, and proposes to adopt the shared station FAS exchange solution, which can reduce the project cost. Meanwhile, it introduces the study on FAS numbering issue and the relevant solution, for providing the reference for reconstruction of digital dispatching communication systems for other existing lines.
