Research of the Measure System in Power Plant

The measure system in power plant based on Orthogonal frequency division multiplexing technology was put forward after the signal sources are described firstly, connected with communication and monitoring networks existed already. In this system, wireless sensor networks or carrier transmission on power line or fiber-optic is used in fully mechanized working face and electric power line systems is used as broadband networks in order to make complete signal transmission system. This system has the advantages of economy,cheapness, good protective measure and “No New Wire”, and exploit the advantage of OFDM, such as strong anti-interference. We compared the typical wavelet basses in practical application, analyzed the effects of the orthogonal bases and its character of orthogonality, compactly supported and vanishing moments in system. System structure of the powered support´ communication system and hardware design, main motion flow of the monitoring equipment were pointed out in this paper.
