铁路时钟同步网由时钟同步节点设备和定时传递链路组成。时钟同步网节点设备分为一级基准时钟、二级节点时钟和三级节点时钟设备,定时传递链路由传输网承担,实现各级时钟设备之间时钟信号的传递。铁路时钟同步网分为骨干同步网、铁路局内同步网。时钟同步网准确地将定时基准信号从基准时钟传递给同步网的各节点,从而调节各时钟保持同步,保证了通信网络的正常运行。
The railway clock synchronization network consists of clock synchronization node equipment and timing transfer link. The clock synchronization network node device is divided into a first-level reference clock, a second-level node clock and a third-level node clock device, and the timing transfer link is borne by the transmission network to implement the clock signal transmission among the clock devices at all levels. Railway clock synchronization network is divided into backbone synchronization network, railway bureau synchronization network. The clock synchronization network accurately transmits the timing reference signal from the reference clock to each node of the synchronization network, thereby adjusting the synchronization of each clock and ensuring the normal operation of the communication network.
