400 MHz数字列调系统对既有450 MHz列调通信的兼容方案
Compatibility Solutions of 400 MHz DRTD System to Existing 450 MHz Radio Communication for Train Dispatching
摘要
Abstract
This paper introduces the compatibility solutions of the 400 MHz DRTD system to the existing 450 MHz radio communication system for train dispatching,covering multiple aspects including wayside and onboard equipment solution,multi-system call interworking solution,console compatible operation solution,data service and CTC system interface adaptation solution.These solutions serve to support the digital transformation of the existing 450 MHz radio communication system for train dispatching of the normal-speed railways,and meet its operational needs during the transition period.关键词
