The Wireless Network Application In Coal Mine Based On Zigbee Technology

In China coal mine safety aspects of the work is not perfect, which leads to the frequent occurrence of coal mine accidents. Coal mine safety has become a hot topic of discussion. From a security point of departure, this paper proposes a mine safety management system based on ZigBee wireless technology.The system uses the IOV-T-2530Innovation experimental platform and CC2530chip models to build a universal system based on ZigBee wireless networks. Eventual realization of a wireless network in the underground real-time personnel to locate and successfully attached to mine real-time temperature and humidity of the environment in the collection, and gas concentration data acquisition subsystem.Firstly, the paper describes the development status of several wireless networks, come to the feasibility and advantages of ZigBee in the coal mine to promote the use of a detailed comparison between several existing wireless transmission network. And then describe in detail the system hardware architecture and circuit design, the entire system is divided into Inoue monitoring subsystem, bus transfer subsystem, and downhole data acquisition subsystem. Through to the study of characteristics of ZigBee technology, protocol stacks and network self-organization, realized personnel positioning and data acquisition capabilities in a downhole environment.Finally, make a summary for the system of this research, practice shows that this set of safety management system has a very broad application prospects and promotion of values. At the end are the specific plans for future work.Figure34Table3References55...
