Embodiment 1

[0039] This embodiment provides a method for precise positioning of fishing boats, such as Figure 1 to Figure 10 shown.

[0040] A method for precise positioning of a fishing boat, comprising: when the fishing boat moves from the open sea to a port entrance, when the fishing boat enters the communication range between the ship-borne terminal and the wake-up base station set at the port entrance, the ship-borne terminal installed on the fishing boat receives the wake-up base station After the wake-up signal is sent, the shipboard terminal is activated from the monitoring state, turns on the satellite positioning module, obtains the location information of the fishing boat, and sends the location information to the dispatching center; the dispatching center is a PC.

[0041] At the same time, the electronic tag in the shipboard terminal continuously sends out radio frequency signals. When the fishing boat enters the port and enters the communication range between the shipboard ...

Abstract

The invention relates to the technical field of port dispatching, and particularly relates to a precise fishing boat positioning method, and particularly a precise fishing boat positioning method in aport. According to the precise fishing boat positioning method provided by the invention, a radio frequency signal emitted by a shipborne terminal in real time, the distance between a positioner receiving the radio frequency signal and the shipborne terminal is calculated through the signal intensity of the radio frequency signal, and since the installation coordinates of the positioner are known, the location of the shipborne terminal is calculated through a three-point positioning method by using the distance information between three shipborne terminals and the positioner. By adoption of the precise fishing boat positioning method provided by the invention, the specific location of a fishing boat in the port can be continuously detected in real time, as long as the fishing boat is in the port, the located of the fishing boat can be detected, the detection time is long, no additional energy consumption is caused, furthermore, the positioning precision is high, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of port dispatching, in particular to a method for precise positioning of fishing boats, in particular to a method for precise positioning of fishing boats in ports. Background technique [0002] Most of the positioning systems used by existing small ships are satellite positioning systems, but the satellite positioning systems consume a lot of power, and the on-board batteries cannot supply power for a long time, and generally can only last for about 3 days. When the fishing boat is moored in the port, the positioning system needs to be turned off, so it is impossible to determine the exact location of the fishing boat in the port. Moreover, the tail box positioning system is greatly affected by the weather, and the positioning accuracy is not high in bad weather conditions. At the same time, when the fishing boat enters the port and berths or sails close to the shoreline of the wharf, due to the large num...
