摘要
阐述了地铁各类无线通信系统的功能及所用技术制式,详细列出了各系统使用的频率;依据各种无线通信系统的运用需求,提出了多条漏泄电缆合并共享的建设方案;明确漏泄电缆的安装位置要求;对隧道中存在的频率干扰进行分析,并提出了应对措施.
The functions and technical modes of various radio communication systems for metro are summarized along with the frequencies used by those systems.According to the operating requirements of those radio communication systems,a construction plan for sharing multiple leaky cables is proposed and the requirements of installation position of leaky cables are also specified.Furthermore,the frequency interferences in tunnel are analyzed and the corresponding solution is put forward.
