摘　　要：当前的大规模智能组卷系统中采用超高频辨识技术完成任务调度,常用的反向散射耦合调度方式因缺少时间上的沟通性而容易产生冲突。为此提出了一种基于功率控制的改进帧时隙防冲突算法。在控制中,引入功率作为调控的依据,读写器按照系统信干比的情况,自主调控自身的发射功率来保证时间间隔,读写器先向作用区域中的标签发送查询命令,记录区域中的标签总数,对信号进行分组描述,在确保读写器读写距离的同时降低信号覆盖区域的繁杂度。实验表明,该方法能够确保信号覆盖区域信号繁杂的最小化,增强智能组卷系统防冲突性能,是一种有效的智能组卷系统冲突消除方法。The current large-scale smart group volume system uses ultra high frequency identification technology to complete the task scheduling, and commonly used scheduling backscattering coupling way is easy to have the conflict due to lack of time on communication. Therefore this paper presented a power control based on the improved frame time- slot anti-collision algorithm. In control, power is introduced as the basis of regulation, and according to the system dry ratio, read and write device independently regulates system itself transmitted power to guarantee time interval, first sends the query command to the label in the function area,records total labels in the area,makes signal grouping its de- scription, ensures the distance of reading and writing, at the same time decreases the complex degree of the coverage area. Experiments show that this method can ensure that signal multifarious minimize signal coverage area, enhance anti-colli- sion performance of smart group volume system, and is an effective conflict resolution method of smart group vo-lume system.
