【摘要】：近年来,随着运动员运动水平的不断提高和现代人们对健身产业的重视,提高自身爆发力的训练逐渐成为人们竞相追逐的焦点,在体育行业表现得尤为突出。本项目基于游泳运动员爆发力训练研究这一条件,研发了自己的一套关于爆发力训练数据收集和分析的系统,给专业人士的爆发力训练和健身爱好者提出科学的健身训练建议。该爆发力系统主要分为上位机和下位机两个部分,下位机主要分为以下三个部分：第一部分是爆发力数据的采集,它包括了一个拉压式传感器和一个速度采集传感器模块,他们主要是将爆发力的压力和加速度分别转化为对应的模拟量和数字量；第二部分是数据的处理,它主要包括了单片机对于拉力模拟量的A/D转换,单片机内部对于加速度数字量的处理；第三部分是数据的传输部分：它主要是一个将爆发力数据由单片机传输到电脑端的蓝牙数据传输模块,方便了上位机软件的研究与开发。这个系统上位机部分最终实现的功能是不仅在单次测量中可以得出爆发力对应的最佳负重值,还能给出不同负荷下的最大爆发力曲线,从而得到科学的训练处方,方便教练进行科学训导。主要的工作包括：1)传感器的选型。拉力的获取选择了测量范围大、测量精度高的YZC-516拉力传感器；速度的获取选择两种可行方案：MMA7455加速度模块和EE-SX671光电开关,通过两种方案可方便的采用不同的安装方式；采用无线传输数据的蓝牙芯片,支持2.0协议；单片机采用AVR单片机,它速度快、片上资源丰富、驱动能力强、功耗低,芯片采用ATMEGA16芯片。2)爆发力的计算。在得到拉力传感器的模拟数据后进行AD转换得到拉力；在得到加速度传感器后对其进行时间上的积分得到速度,或得到光电开关脉冲信号后根据速度等于路程除以时间得到速度：根据即时拉力和速度数据算出爆发力,即拉力乘以速度。3)最佳负重的获取。爆发力训练最佳负荷选择,其实就是找出爆发力最大时所对应的块数,系统在开机后,会记录下当前负荷的块数,然后在开始训练时,不断用“打擂台法”得到最大功率值,在一次训练结束后,将块数所对应的最大爆发力放入存储器；然后更改块数进行训练,系统进行相同的操作。待全部测试结束后,点击“结果”按钮,程序即将不同块数下的最大功率作比较,找出最大功率,最终得到最大功率所对应的块数,即得到爆发力训练的最佳负荷。4)上位机软件程序的编写。主要是实现蓝牙2.0的通讯、数据的传输和计算,在得到下位机的即时数据后,上位机对爆发力的速度-时间、拉力-时间、爆发力-时间曲线进行显示,并找出不同负荷下的最大爆发力值,比较得出爆发力最大时所对应的负重,即得到了训练爆发力的最佳负荷。再利用相应的健身理论对运动员训练或者健身进行评价,指导运动员进行训练或者指导健身者进行科学的健身。
[Abstract]:In recent years, with the continuous improvement of athletes' sports level and the attention of modern people to the fitness industry, the training of improving their explosive power has gradually become the focus of competition, especially in the sports industry. Based on the research of exploding force training for swimming athletes, this project has developed a system for collecting and analyzing the data of explosive force training, and put forward scientific fitness training suggestions for professional exploding force training and fitness enthusiasts. The detonation system is mainly divided into two parts: the upper computer and the lower computer. The lower computer is mainly divided into the following three parts: the first part is the collection of detonation force data, which includes a pull and pressure sensor and a speed acquisition sensor module. They mainly convert the pressure and acceleration of the explosive force into the corresponding analog and digital quantities respectively; The second part is the data processing, which mainly includes the A- / D conversion of the analog pull force and the processing of the acceleration digital quantity in the single chip microcomputer. The third part is the part of data transmission: it is a Bluetooth data transmission module which transfers explosive data from single chip to computer, which facilitates the research and development of PC software. The function of the upper computer part of this system is not only to get the best load value corresponding to detonation force in a single measurement, but also to give the maximum explosive force curve under different loads, so as to obtain scientific training prescription. It is convenient for the coach to conduct scientific instruction. The main work includes: 1) selection of sensor. The YZC-516 tension sensor with large measuring range and high measuring precision is chosen to obtain the tension force. There are two feasible methods for speed acquisition: MMA7455 acceleration module and EE-SX671 optoelectronic switch, which can be easily installed in different ways, and Bluetooth chip with wireless data transmission, which supports 2.0 protocol. The single chip computer adopts AVR microcontroller, which has the advantages of high speed, abundant resource on the chip, strong driving ability and low power consumption. The chip adopts ATMEGA16 chip. 2) the calculation of explosive force. The tensile force is obtained by AD conversion after the simulated data of the tension sensor is obtained. After the acceleration sensor is obtained, the velocity is obtained by integrating it in time, or by the pulse signal of the optoelectronic switch, and then by the speed equal to the distance divided by the time. The explosive force is calculated from the data of the real time pull and the velocity. That is, tension multiplied by speed. 3) the acquisition of the best load. The best load selection for explosive force training is actually to find out the number of blocks corresponding to the maximum explosive force. After the system is turned on, it will record the number of blocks of the current load, and then at the beginning of the training, it will continuously use the "ring method" to obtain the maximum power value. At the end of a training, the maximum explosive force corresponding to the number of blocks is put into the memory; Then change the number of blocks for training, the system to do the same operation. After all the tests are over, click the "result" button, and the program will compare the maximum power of different blocks, find out the maximum power, and finally get the corresponding block number of the maximum power. That is to get the best load of explosive force training. 4) PC software programming. The main purpose is to realize Bluetooth 2.0 communication, data transmission and calculation. After getting the instant data of the lower computer, the upper computer displays the speed time, pull force time, detonation force time curve of the explosive force. The maximum explosive force under different loads is found, and the load corresponding to the maximum detonation force is obtained, that is, the best load for training explosive force is obtained. Then use the corresponding fitness theory to evaluate the athletes' training or fitness, guide the athletes to train or guide the body-builders to carry on the scientific fitness.
