摘要
为了保证广播电视节目的安全稳定播出,需要对广播电视发射机运行状态进行远程监测和控制。基于Web的广播电视发射机远程监控具有很强的适应性和开放性,符合现代远程监控系统的要求。讨论了基于Web服务器的广播电视发射机远程监控的2种方案,给出了基于嵌入式Web的广播电视发射机远程监控系统体系结构和系统功能,介绍了以SX52BD微处理器为核心的嵌入式Web服务器的软硬件设计与实现。针对系统功能的要求,着重对软件设计进行了分析,并提出利用Java Applet和Socket技术在Web页面上实现监控计算机与嵌入式Web服务器进行动态交互的具体方法。系统应用于某电视发射台发射机的远程监控,试运行效果良好。
It is necessary to monitor and control the working states of TV transmitters from remote control center for safety and steady TV broadcasting. Two kinds of Web remote monitoring schemes of transmitters are studied, and the framework and the function of remote monitoring system for TV transmitters based on embedded Web server are presented. The design and implementation of an embedded Web server with SX52BD microprocessor as its core processor are introduced. According to the system functional requirement, the software is designed, and dynamic data exchange on Web pages between supervisory computer and embedded web server is realized with the technologies of Java Applet and Socket. The system is used in a real broadcast transmitting station and expected resuhs are obtained.
