上海局铁路大桥GSM-R覆盖方案研究OA

Targeting at the challenges in railway bridge sections such as complex electromagnetic propagation environments and numerous equipment installation constraints,this paper analyzes the GSM-R coverage scheme for typical railway bridges under the management of China Railway Shanghai Group Co.,Ltd.It gives comprehensive consideration to multiple factors such as wireless coverage requirements,construction difficulty,engineering investment,and maintenance complexity,evaluates the coverage effectiveness through the test data,and also compares and analyzes the advantages and disadvantages of different coverage schemes.The research results indicate that the coverage scheme featuring"base station+repeater+leaky cable"provides uniform field strength distribution,and favorable coverage results,which represents a coverage solution with high prompting value.This paper offers references and insights for the design of communication coverage scheme for railway bridges,contributing to the enhancement of train operation safety and efficiency.
