The invention provides a communication system based on a high-speed urban rail, and relates to a railway communication technology. The communication system comprises a trackside wireless communicationnodes arranged along a track, each node comprising at least two channels, each channel frequency of each node being different from each channel frequency of an adjacent node; the communication systemfurther comprises vehicle-mounted wireless communication equipment which is arranged on a train; the vehicle-mounted wireless communication equipment comprises a first vehicle-mounted wireless communication module, a second vehicle-mounted wireless communication module and a control module, and the control module is used for controlling working channels of the first vehicle-mounted wireless communication module and the second vehicle-mounted wireless communication module according to the position of the train so as to enable the working channels to adapt to the channel frequency of a node where the control module is located. According to the invention, the switching stability and the switching rate of a terminal are improved.
基于高速城轨的通信系统,涉及铁道通信技术。本发明包括下述部分:沿路轨设置的轨旁无线通信节点,每一节点包括至少两个信道,每一节点的每一信道频率皆与相邻节点的每一信道频率相异;设置于列车上的车载无线通信设备,所述车载无线通信设备包括第一车载无线通信模块、第二车载无线通信模块和控制模块,所述控制模块用于依据列车位置控制第一车载无线通信模块和第二车载无线通信模块的工作信道,使其适应于所在节点的信道频率。本发明提升了终端切换平稳度和切换速率。
