| The wireless sensor network is very helpful in information collection of the environment andpersonnel localization in the mine monitoring. To apply the wireless sensor network in minemonitoring, the article makes a systematic study of the software and hardware platforms of thewireless sensor network and succeeds in design of a common system platform for mine monitoring.With layered design in mind, the author classifies the whole system into wireless sensor networknode system, data access layer, data storage layer, service platform layer and application performancelayer in the article. Firstly, a sensor node hardware platform is designed with CC2530RF chip as thecore module. The design of the application programing framework as well as the formulation of nodeapplication program is completed based on Z-Stack operating system under the protocol of ZigBee.Secondly, based on the deficiencies in the current algorithm of wireless sensor network nodelocalization, the article designs a node positioning method based on distributed cooperation bymaking partial improvement in the traditional localization methods. Thirdly, the study realizescommunication, analysis and report of data and suggests a systematic storage of data based oncharacteristics of data of real-time data and massive historical data. Finally, the paper designs aservice platform, formulates a Web-based application program in accordance with practical needs, andthus establishes a mine monitoring system platform with perfect function. Much original work isfocused on the data access layer, data storage layer and service platform layer under the real-timerequirement. Many efforts are done in scalability and reliability of the system.The system platform is finally installed and deployed in a virtue mine project, meets everyspecifications of the project, which proves the feasibility and reliability of the system applied innormal applicaiton environment, and the practical value the system is verified. |
