【摘要】：隨著競(jìng)技體育的發(fā)展,體育科研對(duì)于運(yùn)動(dòng)員成績(jī)的提高起到了越來越重要的作用。對(duì)于鐵餅項(xiàng)目來說,廣泛采用二維平面攝影以及三維測(cè)力平臺(tái)來揭示人體對(duì)鐵餅的作用規(guī)律,并不能清楚的揭示人手對(duì)于鐵餅的作用過程,而這才是體育教學(xué)、教練員和運(yùn)動(dòng)員最關(guān)心的問題。在鐵餅投擲項(xiàng)目中,還沒有出現(xiàn)較理想的測(cè)量設(shè)備。而鐵餅的投擲優(yōu)劣,與鐵餅的受力和投擲角度密切相關(guān),可以近似得到鐵餅出手時(shí)刻的姿態(tài)和受力,基于此來深入研究投擲的全過程,但目前國內(nèi)外還沒有此類測(cè)量?jī)x器。 本文研究的數(shù)字化鐵餅硬件電路系統(tǒng),根據(jù)鐵餅的國際標(biāo)準(zhǔn)設(shè)計(jì)出內(nèi)置電路板的鐵餅結(jié)構(gòu),研制出基于加速度傳感器和角速度傳感器的、能夠得到鐵餅整個(gè)運(yùn)動(dòng)過程中鐵餅的三維加速度和三維角速度信息的鐵餅,獲取的數(shù)據(jù)可以通過無線發(fā)射模塊發(fā)送,并由無線接收模塊接收數(shù)據(jù),最終由計(jì)算機(jī)進(jìn)行處理得到鐵餅的運(yùn)動(dòng)參數(shù),實(shí)時(shí)實(shí)現(xiàn)動(dòng)力學(xué)信息的獲取�？捎糜�(jì)算機(jī)處理數(shù)據(jù),存儲(chǔ)有用信息；能夠單獨(dú)使用,也可以與其它儀器設(shè)備的搭配使用。體育工作研究人員可以借助這種測(cè)量手段獲取的數(shù)據(jù),尋找關(guān)于鐵餅投擲的新理論和新規(guī)律。 本文研究的數(shù)字化鐵餅電路系統(tǒng),經(jīng)過實(shí)際投擲實(shí)驗(yàn)驗(yàn)證,采集到的三維加速度和三維角速度數(shù)據(jù)較準(zhǔn)確,能實(shí)時(shí)無線傳輸,裝置工作穩(wěn)定。通過無線射頻模塊無線傳輸鐵餅運(yùn)動(dòng)過程中的數(shù)據(jù),克服了傳統(tǒng)的有線傳輸方式的局限性,為遠(yuǎn)程獲取設(shè)備的數(shù)據(jù)提供了有效的手段。
[Abstract]:With the development of competitive sports, sports scientific research plays a more and more important role in improving athletes' performance. For the discus project, two-dimensional photography and three-dimensional force-measuring platform are widely used to reveal the law of human body's action on discus, which can not clearly reveal the action process of human hands on discus, and this is the physical education teaching. Coaches and athletes are most concerned about. In the discus throwing event, there is no ideal measuring equipment. The discus throwing is closely related to the force and the throwing angle of the discus, and the posture and force of the discus throwing moment can be approximately obtained. Based on this, the whole process of the discus throwing can be deeply studied. However, there are no such measuring instruments at home and abroad. The digital discus hardware circuit system studied in this paper, according to the international standard of discus, designs the discus structure of the built-in circuit board, and develops the system based on acceleration sensor and angular velocity sensor. The obtained data can be transmitted through a wireless transmitting module and received by a wireless receiving module, which can obtain the three-dimensional acceleration and three-dimensional angular velocity information of the discus during the whole process of the discus movement. Finally, the motion parameters of discus can be obtained by computer, and the dynamic information can be obtained in real time. Use computers to process data and store useful information; can be used separately or in conjunction with other instruments. With the help of the data obtained by this kind of measurement, the researchers of sports work can find new theories and new laws about discus throwing. The digital discus circuit system studied in this paper has been verified by the actual throwing experiments. The collected 3D acceleration and 3D angular velocity data are accurate, can be transmitted wireless in real time, and the device works stably. Wireless transmission of data in discus motion by radio frequency module overcomes the limitation of traditional wired transmission mode and provides an effective means for remote acquisition of device data.
