Based On Wireless Sensor Technology, Mine Safety And Production Monitoring System Design And Realization

With the growing of China's energy demand,the amount of coal mines and coal mine accidents become more and more,which caused huge losses of lifes and state properties. In order to meet the rapid development of the national economy needs, coal mine safety is becoming a top priority work for goverment.Wireless Sensor Network applications can detect the potentially dangerous,as well as deal with coal mine accident.This thesis designed and implemented a coal mine safety production monitoring system which based on wireless sensor network,beside,a multi-function portable sensor network node.The system base on IEEE802.15.4/ZigBee standard,having multi routing, low-cost,low-latency and low power consumption characteristics,that counld resolve the problem for long distance communication.The sensor network nodes have three type: network controller,routers and terminal,they are able to complete the collection and transmission of gas,batteries power and so on.Base on the average energy of the centroid-based algorithm,the system can posite the sensor through the GIS system. Through the test in laboratory and field,the system basic achieve the desire goal,However, wu should improve the hardware and software of the system to become a product applications for coal mine.
