利用PTN搭建铁路视频监控系统网络传输通道

Building Network Transmission Channel of Railway Video Surveillance System with PTN

铁路视频监控系统是保证铁路车站及沿线运营安全的重要手段。通过分析铁路视频监控系统运行现状,以及分组传送网(PTN)的技术优势,得出采用PTN搭建视频监控系统网络传输通道的可行性。分别针对信息系统和通信系统,阐述视频监控系统搭建网络传输通道的PTN技术方案。该方案具有快速、高效、安全、灵活等特点,具有一定推广价值和应用前景。

The railway video surveillance system is a crucial approach to ensure the safety of railway stations and operation along the line. Through analysing the current operation status of railway video surveillance system and the technical advantages of packet transmission network(PTN), the feasibility of building a network transmission channel of video surveillance system with PTN is obtained. Focusing on the information system and communication system, this paper elaborates the PTN technical schemes for building a network transmission channel of video surveillance system respectively. The scheme,characterized by speediness, high efficiency, safety and flexibility, etc., has certain promotion value and application prospect.
