摘要
研究目的:本文从理论分析和现场测试两个角度研究中低速磁浮交通电磁辐射以及对铁路无线设施的影响情况,并提出电磁安全防护距离的概念和计算方法。通过中低速磁浮电磁辐射理论值和测试值,对比铁路无线设施的抗扰度要求,获得中低速磁浮交通与铁路的电磁安全防护距离。研究结论:(1)从理论仿真和现场测试两个维度分析中低速磁浮交通电磁辐射对铁路GSM-R、无线列调、站场无线通信、WLAN、LTE、RFID等典型无线设施的电磁干扰影响,结果表明在相距10 m下,中低速磁浮交通的电磁辐射对铁路无线设施的正常运营不构成电磁干扰;(2)提出了电磁安全防护距离的概念和计算方法,通过电磁辐射理论值与测试值,分别与铁路无线设施的抗扰度要求进行对比分析,得出中低速磁浮交通与铁路各类无线设施的电磁安全防护距离小于1 m,因此在工程建设中,中低速磁浮的电磁辐射不会影响铁路无线设施的正常工作,在线路选线设计时可不考虑电磁辐射的影响;(3)本研究成果可用于了解中低速磁浮交通的电磁辐射原理和对铁路无线设备的电磁辐射影响,可为中低速磁浮交通的工程建设提供参考。
Research purposes:In this paper,the electromagnetic radiation of medium and low speed maglev traffic and its influence on the railway wireless facilities are studied from two aspects of theoretical analysis and field test.The concept and calculation method of electromagnetic safety protection distance are proposed.By comparing the theoretical and test values of electromagnetic radiation of medium and low speed maglev with the immunity requirements of railway wireless facilities,the electromagnetic safety protection distance between medium and low speed maglev traffic and railway is obtained.Research conclusions:(1)From two dimensions of theoretical simulation and test value,the electromagnetic interference impact of electromagnetic radiation of medium and low speed maglev traffic on typical wireless facilities such as railway GSM-R,wireless train dispatching,station wireless communication,WLAN,LTE,RFID is analyzed in this paper.The results show that the electromagnetic radiation of medium and low speed maglev traffic does not constitute electromagnetic interference to the normal operation of railway wireless facilities when the distance is 10 meters.(2)The concept and calculation method of electromagnetic safety protection distance are presented in this paper.By comparing the theoretical value and test value of electromagnetic radiation value with the immunity requirements of railway wireless facilities,it is concluded that the electromagnetic safety protection distance between medium and low-speed maglev transportation and various kinds of railway wireless facilities is less than 1 m.Therefore,in the engineering construction,the electromagnetic radiation of medium and low speed maglev will not affect the normal operation of railway wireless facilities,and the influence of electromagnetic radiation can not be considered in the line selection design.(3)The research results can be used to understand the electromagnetic radiation principle of medium and low-speed maglev traffic and the electromagnetic radiation impa
