【摘要】：气象灾害以及其他公共灾害给人类造成的损失越来越引起社会的广泛关注,提高预警能力,加强预警力度,将灾害预报的信息最早、最及时的传递到需要预警的地区,告知人们做好准备是降低灾害损失的有效途径。如何将预警信息及时准确地传达到灾害发生地,最大程度地降低灾害损失,成为目前迫切需要解决的重大课题。本文以我国广播电视现有资源、技术体系及基础设施为背景提出了研究思路。论文首先对紧急广播消息生成与系统联动、资源管理与资源调度、消息发送的相关协议标准、消息多信道适配封装及消息插入、发布效果评估等关键技术进行了技术攻关。其次,在完成技术攻关之后,论文研制紧急广播消息生成与发布系统各环节关键设备,制定相关标准规范,开发建立紧急广播消息生成与发布系统。最后,系统在试点地区进行分级、分区域、多部门联动的紧急广播应用示范。通过数字有线电视、移动多媒体广播(以下简称CMMB)、中短波和调频模拟广播、地面数字电视、直播卫星、数字音频广播等方式向用户发布紧急广播文本消息或播出紧急广播音频节目。系统的设计和实现为建立国家应急广播体系提供技术支撑。本文设计并完成了紧急广播消息的生成与发布系统。选用J2EE体系进行设计,运用成熟的SSH(Struts2.0,Spring3.0,Hibernate)框架进行布局。通过对紧急广播生成与发布过程的学术研究和实际应用相结合,完成了系统需求分析。系统包括紧急广播控制与消息生成子系统、紧急广播消息发布子系统、紧急广播资源管理与调度子系统、发布效果评估子系统以及网络设备、紧急广播消息接受处理设备、用户前端设备等内容。通过系统需求分析要求,完成了系统设计,包括网络拓扑设计、软件架构设计、流程设计及数据库设计。最后将设计转化为系统实现细节。通过各个模块的实现最终完成了整个系统的实现。
[Abstract]:The loss caused by meteorological disasters and other public disasters to human beings has attracted more and more attention from the society. To improve the ability of early warning, to strengthen the intensity of early warning, and to transmit the earliest and most timely information of disaster forecasting to areas in need of early warning. Informing people to be prepared is an effective way to reduce disaster losses. How to transmit the early warning information to the disaster place in time and accurately and reduce the disaster loss to the maximum extent has become an urgent and important issue to be solved at present. Based on the existing resources, technical system and infrastructure of radio and television in China, this paper puts forward the research ideas. In this paper, the key technologies such as emergency broadcast message generation and system interaction, resource management and resource scheduling, message sending protocol standards, message multi-channel adaptation encapsulation, message insertion, release effect evaluation and so on are discussed. Secondly, after the completion of technical research, the paper develops the key equipment of the emergency broadcast message generation and release system, formulates the relevant standards and specifications, and develops and establishes the emergency broadcast message generation and release system. Finally, the system carries on the emergency broadcast application demonstration in the pilot area, sub-regional, multi-department linkage. Through digital cable television, mobile multimedia broadcasting (hereinafter referred to as CMMBN, medium and short wave and FM analog broadcasting, terrestrial digital television, direct broadcast satellite, Digital audio broadcasting, etc., to issue emergency broadcast text messages to users or broadcast emergency broadcast audio programs. The design and implementation of the system provide technical support for the establishment of national emergency broadcasting system. This paper designs and implements an emergency broadcast message generation and distribution system. The J2EE system is selected to design, and the mature J2EE Struts 2.0 Spring 3.0 Spring hibernate framework is used for layout. Through the combination of academic research and practical application of emergency broadcast generation and release process, the system requirement analysis is completed. The system includes an emergency broadcast control and message generation subsystem, an emergency broadcast message publishing subsystem, an emergency broadcast resource management and scheduling subsystem, a release effect evaluation subsystem and a network equipment, and an emergency broadcast message receiving and processing device. User front-end equipment and other content. According to the requirements of system requirement analysis, the system design is completed, including network topology design, software architecture design, process design and database design. Finally, the design is transformed into system implementation details. Through the implementation of each module, the implementation of the whole system is finally completed.
