摘　　要：考虑到计时成本和计时精度要求,设计了一种基于ZigBee和全球定位系统(GPS)组合的跑步测试系统,用于普通院校学生的长跑体能测试。采用具有高精度定位特性的ZigBee技术实现跑步测试的终点到达判别以及采用便于大范围运动轨迹跟踪的GPS技术实现测试人员轨迹跟踪。对ZigBee定位模块和GPS轨迹跟踪模块的硬件系统进行了设计,并研究了ZigBee定位算法和防碰撞算法以及使用GPS模块进行了捷径作弊判别程序的设计。使用本文设计的跑步测试系统与人工计时方式进行对比,研究结果表明:由人工计时的误差出现了明显的随机性,计时结果不稳定,而由设计的跑步测试系统得到的计时误差稳定性好,基本能够反映出测试者的真实成绩。Considering requirement of timing cost and timing precision,a running test system based on combination of ZigBee and global positioning system(GPS)is designed to complete the task of college students’long-distance running physical test.The ZigBee technique with high precision positioning characteristic is adopted to realize the judgment of end point arrival of running test and to realize the trajectory tracking of the tester by GPS technology which is convenient for wide range movement trajectory tracking.The hardware system of the ZigBee positioning module and the GPS trajectory tracking module is designed,and the ZigBee positioning algorithm and anti-collision algorithm are studied and shortcut cheating judgment program is designed using GPS module.By comparing the designed running test system with the manual timing method,the results show that the error of artificial timing has obvious randomness,the timing result is unstable,and the timing error of the designed running test system has good stability,and can basically reflect the real score of the tester.
