Pinglu Canal is the key project of the Western Land-Sea New Corridor,and building an efficient,intelligent,green,and resilient canal is an important component of the construction of Pinglu Canal with high standard and high-quality.By planning the overall architecture of the smart canal and combining the characteristics and needs of the construction and operation management of Pinglu Canal,the smart construction and management system is proposed as a typical application scenario including “full process integration and coordination of construction and management,full cycle digital twin of progress management,full process simulation and regulation of quality management,all-around early warning and prevention of safety management,and full-link monitoring and early warning of green management”,as well as the typical application scenarios of the smart operation system,including “one-net efficient coordination of operation management,one-body seamless coordination and linkage of operation and dispatch,one-map scientific and intelligent management of locks and maintenance,one-click coordinated and connected emergency response,and one-station efficient and convenient logistics services”.Furthermore,we summarize the innovative technical features of the digital twin Pinglu Canal from five aspects of “full-factorial three-dimensional perception,full-process digital twin,full-process simulation and simulation,all-around intelligent services,and full-technology self-developed and controllable”,which can provide reference for the construction of similar smart port and navigation projects.
