Research Of The Belt Transport Machine Fire Monitoring Node Based On WSN

Coal mining smoothly and underground mine safety are closely related,and the coal mine fire caused by fire and some disasters, directly affect the safety and stability of mine. Timely detection of mine fire period, is the premise to reduce mine fire and reduce fire losses caused by. And as the main cause of mine fire equipment, the fire load coal belt conveyor of coal mine safety personnel to get attention. The traditional coal mine belt conveyor fire monitoring method is often based on a characterization of combustion signal, at the same time, the existing monitoring system for long distance belt conveyors are also very troublesome wiring In view of this situation, mine fire monitoring system design and research based on the wireless sensor network has important theoretical significance and practical application value.How to accurately locate the fire area is the main research direction of the coal mine belt transport machine fire monitoring system,if not timely and accurate positioning to the place of the fire, then the monitoring system also does not have any meaning, improvement of DV-Hop algorithm for DV-Hop location algorithm and the traditional', is proposed based on based on the weighted average method to modify the network average distance per hop improvement scheme, simulation experiments demonstrate the performance of the DV-Hop algorithm, the improved algorithm has obvious advantages compared with the traditional.The nodes of low power consumption, the characteristics of wireless transmission, the system reliability and the needs of field data acquisition principle, the micro processing module, wireless transmission module,wireless communication module and power supply module and the hardware design of the peripheral circuit. And the wireless sensor network node of the software design.The summary of the work and prospects of the wireless senor network is placed in the last.
