Embodiment Construction
[0022] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.
[0023] The embodiment of the present invention relates to a method for tracing the position of a Beidou trawling fishing boat. For the tracing of the fishing boat trajectory, a fishing boat is selected, and the trajectory is counted according to the voyage. Divide into 3 states: slow speed (anchoring, drifting, slow sailing), fishing (trawling), sailing (normal fast sailing), and count the accumulated time of the fishing boat i...

The invention relates to a method for tracing trawl fishing of a beidou boat position. The method comprises the following steps of tracing of a fishing boat track: counting tracks of a fishing boat according to voyages, determining the fishing boat state at each position by means of voyage speed and voyage direction, counting the time accumulation of various states of the fishing boat at a certain fishery in one single voyage, and comparing fishing efficiency; tracing the fishing boat at the fishery: counting the boat position information of all fishing boats at the fishery, and calculating the accumulation fishing time at each fishery in 24 hours according to the track action of the fishing boat so as to calculate the fishing catch of the fishing boat; fishing boat tracing at a fishery fishing area: analyzing the fishing boat source in the fishery and calculating the number of the boats with different sources and the accumulation fishing time in the fishery. The method for tracing the trawl fishing of the beidou boat position is suitable for tracing the trawl fishing of the beidou boat position, helps mastering the source and the accumulation quantity of aquatic products, realizes the tracing of the aquatic products and provides a new means for the safety management of the aquatic products.
Description
technical field [0001] The invention relates to the field of statistical analysis of Beidou ship position data and trawling ship position data mining, in particular to a method for tracing Beidou ship position and trawling fishing. Background technique [0002] In recent years, with the continuous outbreak of aquatic product safety incidents, the quality requirements for the export of aquatic products have gradually increased, and the safety of aquatic products has become the focus of attention of domestic and foreign governments (organizations) and the public. Government interests, as well as the sustainable development of fisheries are of great significance. The traceability of aquatic products based on RFID (radiofrequency identification), electronic codes, and Internet of Things technology has emerged. It is a direct means of quality assurance for all aspects of aquatic products, but it lacks the ability to grasp the traceability of aquatic products at a macro level. Th...
