高铁动车弓网信号对无线通信系统的干扰研究
|
摘要
无线通信系统在高铁运行环境中受到电磁干扰,其主要干扰源来自动车受电弓与电气化接触导线短时相离产生的辐射信号即弓网离线信号。为弄清弓网离线信号辐射主要频段,通过对动车监测采集了大量数据,借助仿真软件对数据进行分析处理,得到频域和时域图表,找到弓网信号辐射区域集中在0.3～1 GHz频率范围,即弓网离线辐射信号处于该频段对无线通信系统干扰最大。这一研究成果为针对性采取电磁防干扰措施提供了重要依据。
Wireless communication system is subject to electromagnetic interference in high-speed railway operation environment, and the main interference source is the radiation signal generated by the short time separation between the pantograph and the electrified contact wire of the locomotive, i.e. the off-line pantograph-catenary signal. In order to clarify the main frequency band of off-line pantograph-catenary signal radiation, through to the locomotive monitoring collected a large amount of data, using the simulation software to analyze data processing, the frequency domain and time domain chart, find the pantographcatenary signal radiation areas concentrated in 0.3～1 GHz frequency range, the pantograph-catenary offline radiation interference signals in the spectrum for wireless communication system is the largest. This research result has important basis for taking electromagnetic interference prevention measures.
