Study of Monitoring System Based on Multicarrier in Power Plant

Electromagnetic interference in power plant is extremely complicated and there are many hidden trouble. The measure system in power plant based on Multicarrier(as OFDM, for example) technology was put forward. The system connected with communication and monitoring networks existed already, wireless sensor networks or carrier transmission on power line or fiber-optic is used in fully mechanized working face. Wireless communication system primarily include digital microwave link or simulation microwave circuits system, etc.. Wireless communication is used in flat area and the time of sudden accident; Power line or fiber-optic is used in mountainous areas or complex landform condition. The technology of Multicarrier combines with multiple access technology and various modulations technology easily. System structure of the communication system and hardware design, main scheme of the monitoring equipment were pointed out in this paper.
