| Abstract (English): |
After a large earthquake, communication facilities are usually damaged and ground communication is not smooth or even interrupted, which will bring great difficulties to disaster relief work. Therefore, it is necessary to establish a reliable emergency communication network. To solve the problems such as single communication means of traditional emergency communication vehicle, difficult cooperative communication of teams and poor effect of returning pictures from disaster areas, an emergency communication scheme that can be rapidly deployed and run stably is studied. It includes the integration of various communication modes and the improvement of the “ last kilometer” communication ability. In communication fusion scheduling, the communication effect of various communication means is tested, and can freely switch the networks of different operators to meet the requirements of earthquake site communication. In the “last kilometer” communication ability improvement, the drone image is connected to the video conference system as a signal to realize the interconnection between the earthquake site and the command center. This scheme can realize the smooth communication network in extreme environment, in which the short-wave communication distance can reach 400 kilometers. The disaster acquisition method can adapt to various communication networks, the transmission frame rate is greater than 30 frames per second, and the picture is clear and smooth.

| Abstract (Chinese): |
大地震发生后通常会导致通信设施损坏, 地面通信不畅甚至中断, 给救灾工作的开展带来很 大困难, 因此需要建立可靠的现场应急通信网络。 针对传统应急通信车通信手段单一、工作队协同 通信难、灾区回传画面效果不佳等问题, 研究了可以快速部署、运行稳定的应急通信方案, 具体包括 现场多种通信方式的融合、“最后一公里”通信能力的提升等。 其中, 现场通信融合调度中, 测试了 多种通信手段的通话效果, 并能自由切换现场不同运营商网络, 以满足现场通信需求;“最后一公 里”通信能力提升中将无人机获取的画面作为一路信号接入到视频会议中, 实现了同指挥中心之间 图像、声音的实时传输。 该方案能实现极端环境下的通信网络畅通, 其中短波通信距离可达 400 km;灾情获取方式能适应多种通信网络, 传输帧率大于 30 frame / s, 画面清晰流畅。 [ABSTRACT FROM AUTHOR] |
