基于嵌入式Web的发射机远程监控系统

摘要

针对目前广播电视发射传输总台人工现场监控发射机操作工作效率低、维护工作量大等一系列问题,设计了一套基于嵌入式Web的发射机远程监控系统.该监控系统将嵌入式Web Server作为中间设备,有效地实现了底层环境参数采集网络和Internet的无缝链接,为管理人员通过Web浏览器方便地对现场环境进行安全监管提供了可能.重点描述了嵌入式Web服务器中CGI的实现方法,并结合C语言编程成功地实现了HTTP连接.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.%Aiming at a series of problem such as low efficiency, a great deal of maintenance and so on of radio and TV transmission for the current total station, the remote control system of transmitter based on the embedded Web is designed. The remote monitoring and control system adopts embedded Web server as an intermediate device to link parameters gathering equipments and Intemet network seamlessly, which can offer some conveniences to managers to monitor environmental parameters of coal mine through Web Browser. The implement strategy of CGI for embedded Web Server is described in detail. Finally, the HTTP connection is successfully achieved with C language program. The system is used in a real broadcast transmitting station and expected results are obtained.
