SYSTEM FOR ACCURACY CONTROL OF ERECTION ON MARINE FLOATING DOCK

摘要

According to one aspect of the present invention, a system for the accuracy control of erection on a marine floating dock is provided, wherein said system can continuously monitor a floating dock based on a rigid quay wall so as to enable a structure to be installed on the marine floating dock and control the accuracy of the installation, and can also efficiently control the accuracy of an inner block. To this end, a system for the accuracy control of erection on a marine floating dock according to one embodiment of the present invention comprises: a monitoring unit arranged on a dock and including a draft sensor for measuring the degree of warp of a dock floor and an imaging unit arranged outside the dock to measure the state of the sidewall of the dock; a measuring unit arranged on the dock to measure, on a real-time basis, the state of a hull block erected on the dock; an erection accuracy control unit arranged on the dock to control the accuracy of the dock which varies as a result of impacts from the hull block erected on the dock; and a control unit including a coordinate-converting unit for converting the information monitored or measured by the monitoring unit and the measuring unit into a single normal coordinate, and an analysis unit for analyzing the state of the dock and the state of the accuracy of the erection on the basis of the converted information, the control unit enabling the erection accuracy control unit to control the accuracy of the dock on the basis of the result of the analysis of the analysis unit. Thus, the floating dock can be continuously monitored on the basis of the rigid quay wall of the dock and the accuracy of the inner block in the dock can be controlled, thereby detecting the state of the floating dock in a more accurate manner and also performing dock ballasting in a more accurate manner.
