The construction of offshore artificial islands lacks high-precision geographical information spatio-temporal benchmarks and effective communication methods.At the same time,there are also issues such as overall settlement monitoring technology and a unified engineering application comprehensive management platform.In view of these problems,digital and intelligent technology for offshore construction of artificial islands is studied.Using BDS-based construction ship maritime positioning communication,digital construction machinery automatic control and BDS high-precision safety monitoring technology methods,the overall architecture and microservice functional architecture of the artificial island digital intelligent construction management platform are designed and developed.The platform is deployed and applied on-site in the Pasay Blow-Fill-Seal Project.The results show that the comprehensive utilization of BDS technology can realize the unified dispatching and command of ships,machinery,and personnel at the construction site,reliable communication guarantee,and artificial island safety monitoring services,and improves the work efficiency and digital intelligence level of artificial island construction.
