In order to meet the construction needs of environmental protection cutter-suction dredgers in the treatment of rivers and lakes and improve the quality of environmental protection dredging,relying on the dredging ship in the Baiyangdian internal source control project,a set of dredging integrated monitoring system has been designed and developed suitable for environmental protection cutter-suction dredgers.The system uses technologies of sensor,measurement,communication,computer,automation to monitor the key construction data of the ship's dredging process in real time,and at the same time integrates the design of the construction plan,post-drought process analysis and remote data sharing,which effectively improves the ship environmental protection dredging accuracy and construction efficiency.
