铁路GSM-R系统电磁辐射计算分析及工程建议

Calculation and Analysis of Railway GSM-R System Electromagnetic Radiation and Engineering Suggestions

根据铁路GSM-R数字移动通信系统基站及无线中继设备功率和频率配置、天馈线及漏泄同轴电缆的技术特性,结合环境保护部及国家质量监督检验检疫总局对电磁辐射的标准,计算出不同场景下满足电磁辐射标准的极值距离,并通过分析提出相关工程建设指导意见,使铁路GSM-R数字移动通信系统引起的电磁辐射满足国家相关规范防护要求。

According to the power and frequency configuration of base station and wireless relay equipment of railway GSM-R Digital Mobile communication system, and the technical characteristics of antenna feeder and leaky coaxial cable, combined with the electromagnetic radiation standards of the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China, this paper calculates and analyses the extreme distance of meeting electromagnetic radiation standards in different scenarios, then gives guidance for the relevant engineering construction by analysis. Thus the electromagnetic radiation caused by railway GSM-R Digital Mobile communication system can meet the protection requirements of relevant national standards.
