摘要: 为解决铁路突发事件应急指挥 “无网、无路、无电”的问题,分析我国铁路应急通信需求及目标,构建公专融合通信的应急指挥网络;通过我国首颗高通量卫星 “中星16号”实现大带宽卫星接入;采用长期演进(LTE)无线宽带技术,实现应急现场的无线宽带覆盖;基于关键任务(MC)技术,实现多媒体应急指挥系统;并通过安全加密技术对网络侧和终端侧进行加密,提供更加安全可靠的通信机制。结果表明:构建的公专融合应急通信网络,能够承载除语音、短数据等基本业务,并支持现场高清视频、高速数据传输等功能,可增强感知事态和信息共享能力,有利于各级应急指挥者研判分析和辅助决策。

Abstract: In order to solve the problem of ″no network, no road, no electricity″ in emergency command of railway accidents, the needs and goals of China's railway emergency communication were analyzed, and an emergency command network of public-private communications was built. Then, large-bandwidth satellite was accessed through China's first high-throughput satellite ″Zhongxing 16#″, and wireless broadband coverage in emergency sites was achieved by adopting LTE wireless broadband technology. Finally, a multimedia emergency command system was developed based on mission critical (MC) technology, and network side and terminal side were encrypted by security encryption technology so as to provide a safe and reliable communication mechanism. The results show that the established public-private emergency communication network can deliver basic services such as voice and short data, and support on-site high-definition video, high-speed data transmission and other functions. Its enhanced perception of accident progress and information sharing capability can assist emergency commander at all levels in accident analysis and decision-making.
