Wind-resistant accurate feeding method for automatic bait casting ship

Abstract

The invention discloses a wind-resistant accurate bait casting method for an automatic bait casting ship. The method comprises the following steps: firstly, carrying out bait throwing experiments of abait throwing machine under various wind direction and wind power conditions, establishing multivariable bait distribution taking wind direction, wind power, bait flow and throwing disc rotating speed as parameters, extracting feature points from the multivariable bait distribution, and establishing a multivariable bait distribution feature point database; a wind direction and wind power sensor arranged on the automatic bait casting ship automatically detects meteorological parameters such as wind direction and wind power on line in real time, and the relative direction of the current wind direction and the bait casting ship is obtained by combining the current heading of the bait casting ship. According to the current bait casting operation breadth and flow requirements and measured parameters such as wind power and relative wind direction, a multivariable bait distribution feature point database is called, function values corresponding to adjacent wind direction variables are subjected to linear interpolation, and the bait density gravity center offset is determined. A new course is obtained by combining the original course and the bait density gravity center offset, and accurate bait casting is achieved.

Description

technical field [0001] The invention relates to the field of operation of a river crab breeding bait boat, in particular to an automatic and precise bait throwing method resistant to the influence of wind force. Background technique [0002] With the continuous development of the economy, people's living standards have improved significantly, and the market's demand for river crabs has increased year by year. [0003] Due to the strong geographical restrictions of river crab farming, river crabs cannot move in a large range and can only forage in areas near themselves; the uneven distribution of bait can easily lead to excessive or insufficient bait, and putting too much bait will not only increase the cost , will also lead to water pollution; at the same time, it is the nature of river crabs to compete for food and aggressiveness, and they will kill each other when the density is high and the bait is small; And fled. Obviously, manual feeding methods and traditional fixed...

[0003] Due to the strong geographical restrictions of river crab farming, river crabs cannot move in a large range and can only forage in areas near themselves; the uneven distribution of bait can easily lead to excessive or insufficient bait, and putting too much bait will not only increase the cost , will also lead to water pollution; at the same time, it is the nature of river crabs to compete for food and aggressiveness, and they will kill each other when the density is high and the bait is small; while fleeing

Obviously, artificial feeding methods and traditional fixed-point feeding machines cannot accurately feed bait
