The invention discloses a drag suction monitoring platform for the dredging operation of the drag suction dredge, which comprises a construction
software, the replay of the historical curve, an
engineering execution, the calculation of earthwork, the computer service procedure, a statement printing and a pattern editor; the invention is characterized in that: the construction
software comprises a
watercraft positioning system, a series of sensors are arranged on a dredging tube and are connected with a
GPS positioning system through a
serial communication port of the computer, which can obtain the three-dimensional locating information of the
watercraft and integrates the monitoring on the navigation, the construction equipment and the construction process through the AIS and the
radar information. The invention integrates the electronic nautical chart technology, the
radar technology, the
computer graphics technology, the network technology and so on; the construction data of the dredger is collected, calculated, processed, analyzed and synthesized to provide a real-time, accurate and effective construction solution for the user, and thus, the output of the dredging operation and the safety of the
watercraft are improved.
