Method for positioning device in coal mine tunnel

The invention discloses a method for positioning devices in a coal mine tunnel, and the method comprises the following steps: S01, arranging more than n radio emission sources with different emission signal characteristics in the coal mine tunnel along the length direction of the coal mine tunnel, n being a positive integer greater than 3; s02, detecting the radio signal strength of each radio emission source at each position in the roadway through a radio receiver, and recording the radio signal strength of each radio emission source corresponding to each position coordinate as record data; and S03, a radio receiver is installed on a to-be-positioned object to detect the radio signal strength of each radio emission source at each position in the roadway to obtain measurement data, and the position coordinates corresponding to the recorded data matched with the measurement data in the step S02 are searched through the measurement data, so that the position coordinates of the to-be-positioned object are obtain
