Zusammenfassung:The invention discloses a mine positioning system based on multiple linear regression and a positioning method thereof. The positioning system comprises an anchor node module, a mobile node module, a positioning formula parameter calculation module, an RSSI value filtering module and an RSSI value positioning module, and a mobile node collects the RSSI value of the broadcast information of an anchor node, carries out regression analysis on data and obtains a positioning formula and parameters; when the system normally works, the mobile node captures the RSSI values of the broadcast information of a plurality of anchor nodes in certain cycle time, the data with relatively low reliability are filtered out by substituting all RSSI values in the filtering module when the cycle time is up, andfinally own position is calculated by using a regression equation and parameters and the position is sent to an aboveground monitoring center through the forwarding-direct transfer of the anchor node. The invention has simple
