[0003] In sports, basketball and football are very popular and have a large number of spectators. Therefore, the market for basketball and football is relatively large, which means that there are many brands on the market, and the product quality of different brands is different. When purchasing at school, because it is difficult to grasp the sales data of dealers, it is difficult to judge which brand of basketball or football is more popular in a timely and effective manner. The user is the touchstone of the product. In order to make it easier for the school to purchase basketballs or footballs, each brand can be bought for a trial first, and the students can test it. For this purpose, a sports equipment material probability statistics based on time series analysis is specially designed. extractor

The invention discloses a material probability statistics extractor based on time series analysis, which comprises a multi-layer sphere carrier formed by a plurality of single-layer sphere carriers. The single-layer sphere carrier is provided with a magnetic force generating structure and includes a plurality of sphere holders. Frame, the sphere brackets in the multi-layer sphere bearing frame correspond to the spheres of different brands, and there are multiple Hall elements on the inner wall of the outer cover cylinder. Connected, the Hall element has different magnetic forces corresponding to multiple sphere brackets according to the magnetic force generating structure. The present invention sets a camera as the main signal collection point and a plurality of Hall elements as auxiliary signal collection points. The rotation of the single-layer sphere carrier is sensed by the Hall element, and it is determined which sphere on the multi-layer sphere carrier is captured. Taking out, through the statistical accumulation of the camera signal and the action data of the Hall element, it is convenient to determine the popularity of each brand of spheres in a time series method.
Description
technical field [0001] The invention relates to the technical field of sports equipment, in particular to a material probability statistics extractor for sports equipment controlled based on time series analysis. Background technique [0002] Sports is a complex social and cultural phenomenon.
