| 摘 要： | 为促进矿山安全生产管理,针对目前矿山井下人员定位不精确,存在定位盲区的现状,提出一种基于加权三边测算的井下人员精确定位新方法。该方法在不增加节点和成本的基础上,将节点布置成三角模式,依据权重对节点进行优选,运用最大概似法论证了定位的精确性。通过实例对加权三边测算法进行了验证,结果表明:该方法定位误差在3 m以内。加权三边测算法能够实现井下人员精确定位,可以运用于矿山的安全生产管理。

| Abstract: | In view of the current situation of inaccurate locating of mine staff and the existing of dead zone,a new method based on measurement of weighted trilateration for accurate positioning of mine staff was presented so as to promote mine safety production management.This method arranged the nodes in triangular patterns without increasing the number of nodes and cost,optimized the nodes according to weight,utilized the maximum likelihood to demonstrate the exactness of location.An application example was given ... |
