Description

A logistics transfer management platform system based on sea transportation

technical field

The invention relates to the technical field of information query, in particular to a logistics transfer management platform system based on sea transportation.

Background technique

Maritime transport: Maritime transport is a way of using ships to transport goods between ports in different countries and regions through sea lanes. It is the most important mode of transport in international trade. The main modes of maritime transport are liner transport and chartering transport. Two categories. Liner shipping is also called regular ship shipping, and charter shipping is also called irregular ship shipping. Liner shipping refers to the regular and repeated voyages of ships on a specific route and between established ports in accordance with a predetermined shipping schedule. It is a mode of transportation that engages in cargo transportation business and collects freight according to a pre-published rate table. Its service objects are non-specific and scattered cargo owners. The liner company has the nature of a common carrier. Chartering means that the charterer pays A method in which a shipowner leases a ship for cargo transportation. It is usually applicable to the transportation of bulk cargo. The relevant routes and ports, the type of cargo to be transported, and the time of voyage, etc., are all confirmed by the shipowner in accordance with the requirements of the charterer. The rights and obligations between the owner and the lessor are determined by the charter contract signed by both parties. Whether it is liner transportation or charter transportation, shipping management needs to be carried out at the port during the transportation process, especially in the logistics transfer. Overall planning and scheduling, so the management platform and management system are needed;

The existing management system, through the use of a management platform, fixedly installs a management platform on each ocean-going cargo ship to realize satellite communication data sharing. Furthermore, it is easy to damage the internal high-precision precision instruments, and when sailing at sea, the air humidity is high, the sealing effect is poor, and it is easy for water mist to accumulate into liquid droplets. In addition, the existing management system can only be artificially planned and dispatched. When planning the optimal path It is more troublesome, so it is necessary to propose a new solution.

The existing management system is troublesome in planning the optimal route, and the existing management platform is easy to damage the internal high-precision electronic components during the navigation process, and the service life is low. Therefore, we propose a logistics transfer management based on sea transportation platform system.
