Corba-based Tv / Fm Transmitter Monitoring System

Along with the network and computer technical fast development, the computersupervision system is applied extensively more and more in these fields such aselectrical power, telecom, energy, traffic, environmental protection and so on. In thefield of television and radio, the automation of management operation and programbroadcasting has received more and more requirement. Many televisions/frequencymodulations launching pads are located on high mountains generally, the traditionalartificial supervision operation is inconvenient, once the occurrence of breaking down,many data can't be saved in time and maintenance work is difficult. The automation ofTV/FM transmitter supervision and control can improve the work efficiency and themanagement level effectively, and it is important to the safety of the program broadcast.Through a research on the computer supervision and heterogeneity in the remote controlsystem, a kind of solution with the CORBA technique is put forward.Firstly, a general introduction of form and elements of local machine's supervisionis given, and the communications of computer with transmitter are introduced. And then,the architecture of CORBA is introduced. With the comparison of other a few ofproducts, the thesis makes an analysis of the advantage of CORBA on supervision andcontrol field of TV/FM.Data polling on transmitters is highly frequent work in the supervision of TV/FM.The state of supervision system can be decided from the raw data obtained from thepolling. While occurrence of breaking down, these data are used to make malfunctionjudgment and device switch. Data Polling is the base of supervision system.The TV/FM transmitter supervision system has been designed and implemented inthe thesis. Through analyzing the characteristics of supervision system, the functionsrequired by user are obtained. The IDL interfaces to the function modules are given,CORBA Naming Service and Event Service are described. According to the design ofthe system, some flow processes about data collection, the control management and thedata search are given. Some tests on the function and performance of the system are done. The further work to the system is put forward.
