System and method for estimating dredging property of drag suction dredger

The invention discloses a system and a method for estimating dredging property of a drag suction dredger. The system comprises three parts: an information acquisition system, an information processing system, and an information display system. The method comprises the following steps: acquiring all the estimation index physical quantities for dredging state by using the information acquisition system of the drag suction dredger; using a calculating module to convert all the estimation index physical quantities for dredging state into three property estimation indexes capable of directly reflecting the dredging state; quantizing the three property estimation indexes capable of directly reflecting the dredging state; setting a weight of the dredging property estimating index of the drag suction dredger; according to each property estimation index and the weight of the dredging property estimating index of the drag suction dredger, estimating the real-time dredging state and periodic property quality of the drag suction dredger; using the information display system to feed back an estimation result and the construction parameters in the optimum period to an operator for guiding the construction. By utilizing the system for estimating property, the malpractice of totally depending on experience is eliminated and the high dredging efficiency is ensured.
