| 摘要: |
| 在介绍ISO 18000-6 Type C协议中标签识别及自适应Q算法操作过程的基础上,利用图表方式分析ISO 18000-6 Type C协议采用自适应Q算法处理标签工作过程的防冲突机制。该防冲突机制采用增减参数C值方法处理冲突问题,能够使系统自动地处于最佳状态,但是该防冲突机制在没有考虑标签应答的情况下对Q值修改时,可能无法保证系统性能最大化,这将影响标签识别的性能。 |

| Abstract: |
| On the basis of the introduction to operation procedures of tag identification and adaptive Q-algorithm for ISO 18000-6 Type C,this paper adopts schematic diagrams to analyze the anti-collision mechanism,which is dealed with by adaptive Q-algorithm of ISO 18000-6 Type C.The mechanism adopts the method of plus or minus parameter c to tackle collision problems,which enable the system to automatically in optimum state.But without considering the status of tag's reply before updating Q,the mechanism can't guarantee the maximum performance of the system,which will affect the performance of tag identification. |
