CN106334300A - Novel damping basket net intelligently detecting basketball net-in - Google Patents

Abstract

The invention discloses a novel damping basket net intelligently detecting basketball net-in, and belongs to the basket type product field, the novel damping basket net comprises an upper net and a lower net; the upper net is conical like a normal basket net, yet the close up port is smaller, so damping can be formed on the basket; the lower net is a contracted prolonged cylindrical or irregular type when compared with a normal basket net, and the net material is not limited. The core purposes are that each net-in status must be damped when compared with a normal net, the damped basket uses longer time to pass the net, and said damping effects cannot be obtained by the normal net; intelligent basketball inner sensors can detect damping change features of the basketball passing the net, thus determining whether the ball has got into the net or not; an in-ball wireless Bluetooth module can send the net-in status to an upper end control machine (mobile phone or computer), thus intelligently recording the shooting hit rate; the novel damping basket net can provide a high efficient passive cheap scheme for the intelligent basketball hit rate detection.

Description

The New Damping net that a kind of Intelligent Measurement basketball networks

Technical field

The invention belongs to basketball class product scope is and in particular to a kind of New Damping net of Intelligent Measurement basketball networking can be provided for user's intelligence basketball.

Background technology

Modern ball game is with the upgrading of electronic product, in order to increase the qualitative analysis of training, many basketball movement systems all sufficiently utilize the kinematic parameter that sensor obtains basketball, and typically using the Parameter analysis movement effects being obtained, the adjustment to motion scheme provides data to support.Wherein basketball shooting hit rate is important indicator, but the existing judgement to basketball networking does not also have the intellective scheme of the universalness of maturation.

Content of the invention

The present invention can provide a kind of New Damping net of Intelligent Measurement basketball networking, sluggish type net for user's intelligence basketball；And damping time bigger to the damping of basketball than common net long it is desirable to, no matter ball networks in what manner it is desirable to it damps on net will reach more than default threshold value by the time.The change that the damping producing during basket over the net is stress is gathered by acceleration transducer various in intelligent basketball, calculates the movement characteristic (or claiming to amplify the movement characteristic wearing net) of basketball networking；Judge whether net in using the movement characteristic of this characterization.Then net state will be entered using the wireless basket tooth module that intelligent basketball ball is embedded in and be sent to upper end control machine (mobile phone, computer etc.), thus the statistics field goalds of intelligence；

The material of net does not limit, but it is favourable to increase damping to spheroid；The shape need of basket ball nets, the top of net is taper as common net, simply less with what lower interface shrank, beneficial to damping；

The bottom of net is the column type of lengthening or special type (s type, screw type etc.) tightening compared with common net, and core purpose is the time by net dampened than common net lengthening basketball.Particularly point out no matter ball networks it is necessary to be damped in what manner；

Basketball passes through to damp physical model during net: basketball networked for four stages, free flight end (f1 section) before a networking, b clashes into backboard, ring, high-speed impact net to the of short duration shock section (z section) stablized before networking, c friction is passed through the net stage (c section), and d goes out the free flight end (f2 section) after net；Subsequently club strikes ground, staff etc..It is crucial that (c section) duration threshold value is passed through the net stage in friction, and current net sight is strong, damping and amortization is weak or damps very little, do not accomplish that every ball all damps all to postpone at all, in addition basketball networking initial velocity is almost non-zero entirely, and so, ball passes through existing net speed quickly, duration value is discrete and little, is unfavorable for measuring and passes judgment on.And each any type of networking basketball of application claims must be damped and wear the net time and have to be larger than predetermined threshold value, the setting of threshold value is relevant with composite factors such as the sampling rate of sensor, the damping sizes of net, setting value has to pass through scientific practice, the setting of threshold value must assure that ball inner sensor stable collect enough characteristics, thus passing judgment on into basket state；

F1 → z → c → f2 characteristic occurs after shooting, and " c " section time have to be larger than threshold value, that is, regard as, into net state, burying a shot.No this state assert that nothing enters net state, misses the basket.This is the core content of the present invention；

It is an object of the invention to improving existing net structure, increasing damping characteristic, being convenient for measuring the networking kinetic characteristic of basketball, thus judging into net state.The amusement strengthening ball game is interesting and intelligent.

Brief description

Fig. 1 is New Damping net schematic diagram of the present invention；The top of in figure 1 net, the bottom of 2 nets, 3 deflation lengthening areas, 4 special types deflations lengthen area；

Claims (6)

1. the New Damping net that a kind of Intelligent Measurement basketball networks

Composition: the top of net, the bottom of net；

The material of net does not limit, but it is favourable to increase damping to spheroid；The shape need of basket ball nets, the top of net is taper as common net, simply less with what lower interface shrank, produces damping beneficial to basketball；
