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。
This paper introduces the wireless data transmission method of Locotrol system in Daqin Line, and analyzes the test data of the 800MHz and 450MHz band in the open circuit of plain, long straight tunnel, curved tunnel and short tunnel group. The results show that in different terrain, Propagation characteristics and error characteristics. It is considered that the 800MHz frequency band wireless data transmission system can meet the needs of locotrol system of 4 × 5000 ton 20,000t combined train operating on Daqin line.
