摘要
在国家现有450~470 MHz频段的相关政策下,对450 MHz无线列调通信系统运用现状和既有存量设备开展动态检测的必要性进行说明。介绍450 MHz无线列调系统和无线场强动态检测启控方式后,对无线列调系统动态检测开展方式进行研究,提出一种450 MHz无线列调动态检测系统,并针对现有场强控发机制弊端,对检测系统给出一些优化建议。
In view of China’s current policies for the 450-470 MHz frequency band,this paper explains the current operation situation of the 450 MHz wireless train dispatching communication system and the necessity of conducting dynamic inspection for the existing in-use equipment.After an introduction to the 450 MHz wireless train dispatching communication system and the starting mode of dynamic inspection of wireless fi eld strength,it studies the operation method of dynamic inspection for wireless train dispatching communication system,and proposes a dynamic inspection system for the 450 MHz wireless train dispatching communication system.In view of the shortcomings of the current starting mechanism for fi eld strength testing,it provides optimization suggestions for the inspection system.
