Abstract： An improved Received Signal Strength Indication ( RSSI ) value localization technology which combined the Received Signal Strength Indication multiple filter,the linear regression distance measurement model and the multilateral location method for miners and equipment was proposed according to the signal transmission model of underground radio channels in this paper,and by using the nodes which were based on the wireless sensor network system TinyOS,an off-line model was built and the on-line calculation was conducted,this thus realized the real-time location of underground miners and equipment. The tests in mine roadways showed that this technology improved the location accuracy, enhanced the system's robust and can be used for underground location.
