英文摘要：

To improve the reliability of the locomotive security system,a design of locomotives video surveillance system based on Hi3521 and Linux operating system was proposed by analyzing the technical characteristics and installing a range of network video system.The technical condition of the video system was analyzed,which identified various functions of the system that need to be implemented,and the framework of the system was established.The hardware part of the system was introduced in detail.By focusing on the video signal sampling circuit based on CX25828 and the Ethernet module circuit,the software design architecture of video surveillance system and terminal control were implemented.A case study of setup planning was presented to verify the feasibility of the method.
