摘　　要：为更好地对青少年体质进行监测,提出一种基于等区域划分的RFID防碰撞算法的体质健康监测手环。首先,利用RFID防碰撞算法对系统的可用性进行改善;然后采用模块化方法对系统结构设计,并分别从系统硬件和软件角度进行具体设计;最后,对RFID防碰撞算法性能和软硬件进行测试和分析。测试结果表明,RFID防碰撞算法的时隙数比FSA_256和DFSA算法分别低了82.54%和83.18%,说明该算法能够减少碰撞时隙和系统识别时间,提升系统的性能。同时系统测试表明,手环系统可实时、准确地监测到青少年的体质信息,有利于教师监督学生进行体育锻炼,从而提升学生的身体素质。In order to better monitor teenagers’physique,a physique health monitoring bracelet based on RFID anti-collision algorithm with equal area division is proposed.Firstly,RFID anti-collision algorithm is used to improve the usability of the system;Then the modular method is used to design the system structure,and the specific design is carried out from the perspective of system hardware and software;Finally,the performance of RFID anti-collision algorithm and software and hardware are tested and analyzed.The test results show that the number of time slots of RFID anti-collision algorithm is higher than that of FSA_256 and DFSA algorithm are 82.54%and 83.18%lower respectively,indicating that the algorithm can reduce collision time slot and system identification time and improve the performance of the system.At the same time,the system test shows that the bracelet system can monitor the physical information of teenagers in real time and accurately,which is helpful for teachers to supervise students’physical exercise,so as to improve students’physical quality.
