NAVIGATION SYSTEM FOR TOWER CRANE

摘要

PURPOSE: A navigation system for a tower crane is provided to make a tower crane driver safely lift materials by providing various types of image information. CONSTITUTION: A navigation system for a tower crane comprises a material position measuring part(100), a structure measuring part(200), a path searching part(400), a path storing part(450), a data processing part(300), and a display(700). The material position measuring part measures the position of materials lifted by a tower crane. The structure measuring part measures the position of structures within the operational radius of the tower crane. The path searching part searches a moving path of the materials lifted by the data of the material position measuring part and the structure measuring part. The path storing part stores the path searched in the path searching part according to the tower crane. The data processing part calculate two or three dimensional image data indicating the relative position of the tower crane and the materials and structures lifted by the tower crane by receiving the data of the material position measuring part and the structure measuring part. The display indicates at least one of the tower crane, the materials, or the structures by using the image data calculated in the data processing part and indicates the moving path searching in the path searching part.
