Service environment of large-scale ocean engineering structures is harsh and the extreme marine environment can easily cause various types of structural damage to large-scale ocean engineering.Traditional monitoring methods are no longer applicable to the requirements of intelligent ocean engineering monitoring technology.Hence

a crucial problem to be solved is how to use modern monitoring technology to realize precise monitoring and sensing of large-scale ocean engineering structures.An intelligent monitoring and early warning system that can be applied to the safety of ocean engineering structures is developed by integrating advanced sensors

sensor data acquisition chips

micro-control processor and wireless transmission modules.Characterized by low power consumption

long-distance and real-time monitoring

and it is demonstratively applied to typical cross-sea bridges such as Zhoudai bridge in Zhejiang province.Tests are carried out in the laboratory tank environment based on the monitoring requirements of offshore wind turbines.The application results show that this system can accurately sense the dynamic response of the ocean engineering structure and realize the real-time monitoring and sensing of the state of the ocean engineering structure.
