Boundary control method of ship

Abstract

The invention discloses a ship boundary control method, which is used for controlling a ship without a power supply and is based on a ship boundary control system, the ship boundary control system comprises a management platform and a ship terminal fixedly connected to a ship body, and the ship terminal comprises a solar charging module, a positioning module, a communication module and a control module; the solar charging module is used for supplying power to each module; the positioning module is used for acquiring and sending positioning information to the control module; the communication module is used for receiving and forwarding the positioning information to the management platform and forwarding the parameter setting instruction to the control module; the control module is used forreceiving the parameter setting instruction, storing parameter values in the parameter setting instruction and controlling the positioning module and the communication module according to the parameter values; the management platform is used for receiving and processing the positioning information to determine a distance value between the ship and the boundary, setting a parameter value accordingto the distance value and sending the parameter value to the communication module; and the management platform judges whether to give an alarm or not according to the distance value.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, in particular to a ship boundary control method. Background technique [0002] Generally speaking, the ship's border control system includes a management platform and a ship terminal, and the ship terminal is fixed on a small fishing boat without power generation equipment; among them, the ship terminal includes a solar charging module, a positioning module, a communication module and a control module. [0003] Since there is no power generation equipment on small fishing boats, the positioning module, communication module and control module can only be powered by solar charging modules to convert solar energy into electrical energy. However, due to the small size of the ship terminal itself, the area of ​​solar panels is also limited, and the sea surface The situation is complicated and the climate is changeable, so the charging efficiency is also easily affected, so that each module c...

Problems solved by technology

[0007] However, when the ship is close to the boundary, the above-mentioned technical solution may have the following problems: (1) due to the excessively large parameter value during the positioning period and the reporting period of the positioning information, when the ship has crossed the boundary or is very close to the boundary, The management platform does not have time to respond to the missed report; (2) Due to the small parameter value during the positioning period, there is a large deviation between the positioning information obtained by the positioning module and the current actual position of the ship, and under the influence of bad weather, then It will further increase the gap between the position of the ship in the positioning information and the actual position of the ship, such as Figure 9 As shown, the positioning information may show that the ship has crossed the border but the ship has not actually crossed the border, which is a false alarm issued by the management platform
