摘要

如何优化扫描码的扫描步骤和组织结构是提高电调天线设备扫描防碰撞算法识别效率的关键. 通过研究扫描码中掩码和匹对码的组合形式对扫描时间的影响，获得用掩码逐位段扩展的方法来逼近设备UID，以减少设备扫描时间. 同时针对整个扫描过程，采用分层分析方法导出较优的掩码扩展位数，证明二位掩码扩展方法较优.根据这一结论构造扫描码，提出改进的基于二位掩码扩展的电调天线设备扫描防碰撞算法. 仿真分析证明了该算法具有较优的扫描性能.

Abstract

Optimization of structure and scanning steps of scan codes is a key to improving recognition efficiency of scanning anti-collision algorithm for antenna line devices (ALD). By studying the influence of combining the mask and matching code on the scanning time, the mask extension by bit can be achieved to
approach the device UID so that the scanning time is reduced. Meanwhile, from layered analysis, optimal bit number is obtained in the mask extension. The two-bit mask extension has been shown to be optimal. Accordingly, scan codes are constructed, and a scanning anti-collision algorithm for ALD based on the two-bit mask extension is proposed. The simulation analysis shows the good scanning performance of the proposed algorithm.

Key words： antenna interface standards group (AISG) protocol; remote electrical tilt; device scanning; algorithm performance
