[Abstract]:In accordance with the relevant national development policies and the concept of realizing a safe, efficient and green port traffic system, a port hydrological environment system based on network services should be established by making full use of the port marine hydrological survey data. It provides more comprehensive and convenient port hydrological information for port transport operators and port stakeholders, further improves port transport efficiency and improves the safe navigation coefficient of ships in and out of port. Based on the concept of "promoting production with safety", this paper constructs a network service system of port marine hydrology information, implements safety management, network communication, scientific design and digital processing. By strengthening the information service of marine hydrological and physical environmental elements of the port, the efficiency of ship entering and leaving port can be maximized under the premise of safe operation, and the port transportation cost and management cost can be effectively reduced. Therefore, it is necessary to obtain the hydrological parameters of the port more quickly and issue them to the port management system and the incoming and outgoing ships in time. How to obtain the port hydrological information quickly is of great significance to ensure the safety of ships entering and leaving the port and to improve the efficiency of port operation. Based on the B / S architecture, a general port hydrological data management database and related database management application system is constructed. Based on this, a port marine hydrological data network service platform is established. Through modeling the data collected by the system and establishing the hydrologic information forecasting model, the network real-time release of marine hydrological data is realized. According to the customers' demand for port marine hydrological information, it is more convenient and fast. Reliable information service. This paper introduces the system selection database and related system development software, constructs the whole structure of the network service port marine hydrological information system, and discusses in detail the design process of the network service port marine hydrological information system architecture. The wave data processing module and the prediction model of some elements of ocean wave information are described in detail. The main contents include the analysis and comparison of each wave spectrum, and finally, the wave spectrum selected by the system is given. By studying various forecasting models and finally introducing the research theory related to neural network into the wave prediction model, a set of ocean wave prediction model based on BP neural network is designed. Finally, the key design of the application system is described in detail.
