HIGH-ACCURACY METHOD WITH USE OF DOUBLE LABEL FOR MOVING TARGETS POSITION FIXING IN MINE

摘要

FIELD: measuring equipment.;SUBSTANCE: high-accuracy position fixing method with the use of double label includes a method for locating a position fixing of an object of the first type in a mine and a method for position fixing of a moving object of the second type in a mine; the method includes the steps of: setting two position labels horizontally or vertically on a moving object and performing them to communicate with two base positioning stations installed along the roof timber and obtaining the location of the moving object in real time by constructing an optimisation function between the distance determined according to the received signal strength indicator and the estimated distance between the label and the base station of position fixing and searching for the minimum value; solving the optimisation function by an iterative process, including the step of determining the initial iteration value and the iteration step in the left/right direction. The method is applicable for determining the location of objects with a strip profile parallel to the digging face (for example, a mine trolley or a cutter) or objects with a strip profile perpendicular to the digging face (for example, a working).;EFFECT: improved accuracy of position fixing of a moving object in the mine.;2 cl, 2 dwg
