| Abstract: | The paper introduces three communication networking schemes of the disaster prevention safety monitoring system for high-speed railways with the analysis of the networking principle, protection handover principle and operation flow of the three schemes. It concludes that the tree-type networking scheme is the best one by a comprehensive analysis from such aspects as network reliability, transmission delay, transmission bandwidth, engineering investment and implementation difficulty, and it is of reference value for engineering designs in the future. |
