Intelligent boxing glove based on optical fiber sensing technique

Abstract

The invention discloses an intelligent boxing glove based on an optical fiber sensing technique, comprising a leather layer, a first sponge medium layer, a second sponge medium layer, optical fibers,a sensor, a signal processing and displaying device, a wristband, round holes in the upper surface of the second sponge medium layer, round holes in the lower surface of the second sponge medium layer, round holes in the lateral side of the second sponge medium layer, an airbag, an air tube, an inflating nozzle and a third sponge medium layer. The intelligent boxing glove based on the optical fiber sensing technique has the advantages that all the first sponge medium layer, the airbag and the third sponge medium layer provide certain anti-punch protection for the optical fibers, the intelligent boxing glove is capable of accurately and stably measuring boxing force and boxing speed based on the optical fiber sensing technique; the intelligent boxing glove is capable of displaying boxing force and speed data in time and reflecting magnitude of the punching force by the aid of flashing speed of an indicator light; motion information data such as boxing force and boxing speed are transmitted to a cellphone and a computer through Bluetooth, WiFi and other wireless modules for use in human-machine interactive software.

Description

technical field [0001] The invention relates to an intelligent boxing glove, in particular to an intelligent boxing glove based on optical fiber sensing technology, which belongs to the technical field of sports applications. Background technique [0002] Boxing gloves are one of the necessary protective gear for people in boxing matches and boxing sports, and their function is to protect the boxer's wrist and finger joints. With the progress of society, practitioners are more and more concerned about their punching speed. Although the traditional boxing gloves on the market have a good cushioning effect, relying on the traditional boxing gloves, the practitioner cannot obtain quantitative sports index data such as boxing power and boxing speed in time. [0003] In order to obtain the above-mentioned boxing sports index data, the authorized announcement number CN 202223862 U, the Chinese invention patent named "Smart Boxing Gloves" is equipped with an acceleration sensor an...

Problems solved by technology

The problem with this solution is that because the data collected by the acceleration sensor is affected by the acceleration of gravity, without the correction of the gyroscope and magnetometer data, the actual punching speed cannot be calculated only by the acceleration sensor; even if the gyroscope and magnetometer are used However, due to the cumulative error of the gyroscope and the susceptibility of the magnetometer to the interference of the surrounding magnetic field, the calculated punching speed is not accurate.

Lithium niobate static crystal sheet is a kind of piezoelectric material. Its disadvantages are: firstly, piezoelectric material can only be used for kinetic energy measurement, and how to accurately calculate the impact force according to kinetic energy has not been published; secondly, piezoelectric Materials are slower to recover when subjected to sudden vibration or excessive stress

[0005] Authorized announcement number CN 205886166 U name, a Chinese invention patent named "portable boxing gloves with measurable force" using a pressure sensor to detect hitting strength, authorized announcement number CN 205460877 U name "a kind of smart boxing glove" Chinese invention patent uses strength The sensor detects the strength of the punch, but neither of the two patents specifies the material, type and working principle of the pressure sensor or force sensor
