英文摘要： According to the urgent requirements for wireless video surveillance, voice communication, environmental monitoring and target localization by mine security monitoring, early warning and disaster relief, a wireless multimedia sensor network for underground coal mine is proposed which is based on the multi-band orthogonal-frequency-division-multiplexing ultra-wideband (MB-OFDM-UWB). It will provide strong support for mine security monitoring, early warning and disaster relief, and also enhance the abilities of them greatly. Models of multimedia monitoring of the wireless multimedia sensor network for underground coal mine will be established which will lay the foundations for the study of key technologies of the network. Proposed technologies of network coverage and topology control to optimize network coverage under the premise of guaranteed QoS. Proposed the MAC protocol and routing protocol according to QoS guarantee of different service to ensure the efficient operation of the network. Establish the interaction mechanism between different layers of protocol stack with the method of cross layer design to provide better QoS guarantee. Put forward the method of cooperative target localization through the perception of multi-nodes according to the characteristics of underground coal mine monitoring scene. Lay a foundation for the future theoretical and technical development of wireless multimedia sensor networks of underground coal mine, and improve the wireless monitoring theory and technology for underground coal mine in our country.
