基于DVB/IP的气象应急卫星通信系统的设计与应用

摘要

For data transmission of mobile Doppler weather radar,the consultation for emergency communication, and the broadcast of major weather process, a meteorological satellite communication system based on DVB/IP was designed, which integrates several high technologies including satellite communications, computer network, wireless communication, multimedia production, image transmission and so on. Considering the requirements of meterological disaster prevention and mitigation, the data collection and communicaton function of the system can provide technical support for meteorological emergency management and decision-making process. The application of this system will improve the emergency response capability of Shanghai Meteorological Bureau.%为配合移动多普勒气象雷迭车的数据传输,实现应急通讯的会商以及重大天气过程的直播和保障,利用卫星通信、计算机网络、无线通信、图像传输、多媒体制作等多种技术集成设计了DVB/IP气象应急卫星通信系统.该系统从数据收集和通信层面上立足于气象防灾减灾的需求,为气象应急保障服务和决策指挥提供了强有力的技术支撑,将对上海市气象局应急处置能力的提高起到一定推动作用.
