Application of the 'Ciyun' Intelligent Precise Positioning System in Lijiahuo Coal Preparation Plant
Abstract：The complex three-dimensional structure and severe shielding within the main workshop of the coal preparation plant, as well as the screening and crushing workshop, make it difficult to apply existing positioning technologies. The presence of a large number of harmonics and electromagnetic interference from variable frequency electrical equipment further complicates the situation. Existing positioning technologies face various issues when applied indoors in coal preparation plants, such as low positioning accuracy, limited coverage of Bluetooth technology, and complex base station deployment and construction. Therefore, the personnel positioning system in coal preparation plants has not been widely applied.
