The article mainly emphasized on researching the technical solutions andimplementations for mine safety monitoring system architecture and wireless locationtechnology.On the basis of introducing the architecture of wireless sensor networks firstly, thepaper introduced the various parts of function of the mine safety monitoring systemstructure and the hardware and the software platform in detail, and then according to thescope of application of several classical wireless signal propagation model. As well asthe analysis and comparison of the ranging-based localization algorithm and the withoutranging localization algorithm. Taking into account the complex special environmentin the mine and the cost of deploying wireless sensor networks, The RSS-basedlocalization algorithm of without ranging is chose.To meet the positioning accuracy of the underground workers and engineeringrequirements. In mine safety monitoring system architecture, it introduced the real-timemonitor systematic structure into which it integrated all three aspects of tracking andpositioning, life feature detection, voice calls for the underground workers. In thewireless positioning of the underground workers,In the view of the shortcomings ofthe traditional standard beta value localization algorithm, the Real-time dynamicacquisition Beta value localization algorithm is Proposed.In the safety of monitoring system architecture, for the particular structure of themine tunnel. the network structure is which anchor nodes are Bilaterally deployed in thetunnel. For the designing plan of mine safety monitoring system that based on WSN, itintroduced the real-time monitor systematic structure into which it integrated all threeaspects of tracking and positioning, life feature detection, voice calls for theunderground workers. This would not only be able to improve the security of theoperating personnel, but also it would decrease the casualties on the maximum oncesomething dangerous happened.For wireless location technology used in mine safety monitoring system. Firstly, onthe basis of the traditional standard beta value algorithm, For the problem which RSSvalue is susceptible to environmental interference, the Real-time dynamic acquisitionBeta value localization algorithm is Proposed. The Location algorithm of real-timedynamic acquisition Beta value is divided into two parts, The algorithm of obtaining dynamic path loss parameter and the advanced RSS localization algorithm.Theimproved algorithm is based on the characteristics of the RSS ranging, Beta value ofconstantly changing is real-time Received in the wireless channel. Simulation resultsshow that the advanced algorithm significantly improve the defects of the traditionalstandard beta valuealgorithm. Optimize the localization accuracy of target. In theend,the paper gives the analysis of the influence of the positioning results of anchornode deployment density and mine width.In setting up the mine safety monitoring system architecture.The experimentalresults show the Real-time dynamic acquisition Beta value localization algorithm isadapted to achieve positioning accuracy which can basically meet the positioningrequirements of mine safety monitoring system for underground workers.
