摘要
为解决篮球运动的生理监测设备的性能问题和精度问题,研究将根据监测目标进行模块化分置。鉴于大多数生理监测设备难以适应运动环境,研究将设置胸部节点、腕部节点和头部节点,用来采集球员们心率、脉搏、体温和位姿情况。通信采用蓝牙低能耗技术进行传导,但该技术下各个节点之间的传导存在延迟以及晶振振荡误差,在进行相关补偿后显示时间误差并未随设备运行而累计,并成功地将时间误差从毫秒级降低到微秒级,最终误差均不超过150μs。对设备监测性能进行测试,结果表明该设备能完成相关数据采集,这为篮球运动员素质能力提升提供帮助。
In order to solve the performance and accuracy problems of physiological monitoring equipment for basketball,the re-search will be based on the monitoring objectives of modular separation.Since most physiological monitoring devices are difficult to a-dapt to athletic environments,the study will have nodes on the chest,wrist and head that will collect the players'heart rate,pulse,temperature and posture.The communication is conducted by Bluetooth low energy technology,but there is delay and crystal oscilla-tion error between each node under this technology.After relevant compensation,it is shown that the time error does not accumulate with the operation of the equipment,and the time error is successfully reduced from millisecond to microsecond,and the final error is less than 150μs.The monitoring performance of the equipment is tested,and the results show that the equipment can complete the relevant data collection,which provides help for the improvement of the quality and ability of basketball players.
