The system consists of warning tips, early warning for different media and early warning query statistics and the network terminal of the system platform includes a business database server, a message platform database server, a sending server and a receiving terminal. The system enjoys some func- tions, such as examination by different users, on-time updating and effectiveness of flood prevention, construction of excessive warning channel, construction of compre-hensive warning information platform and further improvement of information distribution. The system provides references for prevention and reduction of important me- teorological disasters in Hunan.展开更多
气象警报卫星广播(DAB)系统具有覆盖面广、时效高、不受地理限制的特点,从根本上解决现有其他发布方式(如手机短信、电话等)无法覆盖边远、偏僻农村、荒漠、海岛、海洋船只等边远地区的缺陷,可以很好地解决上述地区预警信息发布的"...气象警报卫星广播(DAB)系统具有覆盖面广、时效高、不受地理限制的特点,从根本上解决现有其他发布方式(如手机短信、电话等)无法覆盖边远、偏僻农村、荒漠、海岛、海洋船只等边远地区的缺陷,可以很好地解决上述地区预警信息发布的"最后一公里"问题.本项目设计并建立江西省 DAB 气象灾害预警信息编辑、传输、发布、接收系统,解决通过 DAB 广播向灾害预警区域智能化定向发布信息技术问题,建立信息发布的业务流程,实现气象警报卫星广播(DAB)系统在江西省气象灾害预警信息发布的业务应用.展开更多
