The system provides the mechanical status and production operation data of the construction vessel in real time, and can fully realize the real-time display of dredger flow rate, concentration, suction vacuum, discharge pressure, reaming speed, underwater pump speed and operating parameters of various mechanical equipment. Intuitive graphical display and digital display are provided for accurate dredging by construction operators. At the same time, the data of dredger construction operations will be transmitted to the land server in real time, which is convenient for land experts to analyze, diagnose and guide the construction situation. The system can observe the construction situation in real time, play back historical data, and also output data tables and analysis curves. Combined with the soil quality and hydrology of the construction site, the project management department can fully control the ship construction situation, analyze the operation efficiency, formulate the operation plan, and formulate a reasonable bidding plan according to the previous operation efficiency.
