摘要
地铁信号系统车地无线通信和乘客信息系统车地无线通信工作在同一频段,需要采取一定的措施来避免两者之间的干扰。从不同频段、不同信道的角度介绍了目前我国地铁在信号系统和乘客信息系统的兼容性上所采取的2个解决方案。
Signal system for train/ground wireless communication and passenger information system for vehicle wireless communication are working in the same frequency band,some measures must be taken to avoid the interference between the two systems.In this paper,two compatibility schemes are analyzed from the angle of different frequency bands and channels.
