基于数字卫星广播电视模块需求的广电监测系统设计

该文基于数字卫星广播电视监测的业务需求和功能需求,设计一种能够实时监测卫星广播电视信号,并自动分析信号和直观展示分析结果的应用系统。该文首先从音频、视频信号的动态监测、压缩存储、系统维护及网络互联等方面,对数字卫星广播电视系统的业务需求、功能需求展开分析。随后按照需求导向原则,基于B/S架构和Servlet技术设计由Web控制层、业务逻辑层、数据持久层组成的数字卫星广播电视监测系统。该系统可根据实时监测数据动态,直观地显示广播电视节目的播放情况,并实现异常报警,为实现无人值守和故障自动恢复提供积极帮助。

Based on the business and functional requirements of digital satellite radio and television monitoring,this paper designs an application system which can monitor satellite radio and television signals in real time,analyze the signals automatically and display the analysis results directly.Firstly,this paper analyzes the business requirements and functional requirements of digital satellite radio and television system from the aspects of dynamic monitoring,compression and storage of audio and video signals,system maintenance,network interconnection and so on.Then,according to the demand-oriented principle,a digital satellite radio and television monitoring system is designed based on B/S architecture and Servlet technology,which is composed of Web control layer,business logic layer and data persistence layer.The system can dynamically and intuitively display the broadcast of radio and television programs according to the real-time monitoring data,and realize abnormal alarm,which provides positive help for the realization of unattended and automatic fault recovery.
