Abstract:
1. A tower crane navigation system comprising: a material position information measuring section for measuring a position of a material lifted up by a tower crane; a structure information measuring section for measuring position information about structures within and/or beyond a working radius of the tower crane; a route searching section for searching for a route of movement of the material lifted up, from a start point to a destination; a route storage for storing the route of movement determined by the route searching section with respect to each tower crane; a data processing section for receiving data from the material position information measuring section and data from the structure information measuring section, and for calculating two-dimensional (2D) or three-dimensional (3D) image data which provides information about relative positions of the tower crane, the material lifted up by the tower crane and the surrounding structures; and a display unit for displaying information about at least one selected from the group consisting of the tower crane, the material lifted up by the tower crane and the surrounding structures, using the image data calculated by the data processor, and for displaying the route of movement determined by the route searching section, wherein the route searching section searches for the route of movement by carrying out one mode selected from the group consisting of a safety first mode, a productivity first mode and a previous route mode.
