Key technology of mine gas monitoring and measuring data issue system based on sensor network

According to the disadvantage in the heterogeneous sensor resource integration of the mine gas monitoring and measuring with the traditi onal industrial Ethernet and the advantage of OGC sensor network framework in the heterogeneous sensor resource integration,collaborative monitorin g and measuring,and fast response,a data issue data system of the mine gas monitoring and measuring was designed based on sensor network. The p aper in detail stated the data access technology of the monitoring and measuring based on sensor network and the data storage technology based on Mongo DB. The technology was successfully applied to Wangjialing Mine. The application results showed that the service technology of the sensor net work broken the low efficient working mode of the traditional Ethernet and could provide a possibility of collaborative observation in the underground mi ne. The No SQL storage technology was applied to achieve the real time access,mass storage,high efficient search and dynamic management of the m onitoring and measuring data from the sensor network in order to set up the base of future intelligent mine construction.
