Research On Spatial Issue Of The Communication Stability In Open-pit And Its Application

The importance of "data" in open-pit production management is self-evident. Theinstability of the wireless network and mobility of devices are threatening the stabilityof data transmission. In this dissertation, an open-pit production management system istaken as the research background, to explore the strategy to guarantee the stability ofspatial location-based mobile data transmission. In the light of the characteristics ofmining environment, by contrasting the dependency between signal strength,transmission distance, the delay time and wireless network status in mining area, it isfound that the Kriging interpolation results obtained by taking the delay time as anindicator can accurately reflect the network status. The spatial query method applicableto Kriging interpolation results is proposed: interpolation results is transformed intovector form, and the feature value is extracted, then spatial query is conducted by themethod of combining the minimum bounding rectangle with accurate spatial judgment,thus achieving dynamic queries of mobile terminal to the network status. Thefeasibility of the method has been verified. The research introduces the transactionalproperty-based workflow management to open-pit mobile terminal transactionmanagement and optimizes them. With truck terminal as example, it is proved that thestability of data transmission can be improved through the above mentioned method,thus providing guarantee for the open-pit production management.
