Shearer positioning is a key technique applied for mining fleet automation, such as shearer adaptive cutting and hydraulic support automation. This paper proposes a distributed positioning detection method of shearer based on the dual mapping between the signal domain and spatial domain. Firstly, anchor nodes are selected in the communication range of mobile node, thus dynamic coordinate system is established in target subspace. Secondly, based on measuring distance and positioning algorithm, shearer positioning is resolved by taking actual operation of shearer along scraper conveyor as constraint condition.
