Based On D-S Decision-making's Mine Environment Monitor

Recently, there are a lot of mine accidents in our country and the Poor monitor system is the main reasons. In this thesis, for the single sensor monitor system data's weakness of uncertainty and insufficiency, this system uses the multi-sensor's information fusion technology which base on D-S decision-making to resolve this problem. It can be used to analysis processing monitor's data and evaluate the safety of mine's working conditions by multi-parameter which was disposed by information fusion module. Based upon the correlation of the parameters, more information can be acquired, which couldn't be completed by single sensor monitor system. This method makes the data acquisition more credibility and more comprehensive. Meanwhile, it utilizes the technology of multi-sensor's information fusion combination with virtual instrument to exert the powerful data processing ability and favorable manipulate of the virtual instrument monitor. With the new technique, it increases the monitor system's validity greatly.
