摘要
介绍大秦线Locotrol系统的无线数据传输方式,分析800MHz和450MHz频段电波在平原开阔地带、长直隧道、曲线隧道、短隧道群弯曲线路中的测试数据,得出不同频段电波在不同地形条件下的传播特性及误码特性。认为采用800MHz频段无线数据传输系统,能够满足在大秦线开行4×5000吨的2万吨组合列车Locotrol系统应用的需要。
In this paper, we discussed radio data transmission mode of Locotrol system on DaQin line and concluded the propagation and error-code characteristics of different wave band radio under different landform and by analyzing the test data in plain area, long straight tunnel, curving tunnel and short tunnel group for 800MHz and 450MHz wave band radio. It was concluded that 800MHz wave band radio data transmission mode can meet the application requirement of operating 20kt over hauled train on Dalian-Qinhuangdao Line.
