摘　　要：为有效解决电子导游系统中有时不能精确播报景点信息的问题,提出了一种电子导游机极易出错情况下的特定算法来改善其播报精度。该算法基于RSSI定位技术基础上,利用用户节点移动的历史信息和最近邻居节点信息来辅助导游机判断游客对景点的观赏需求,以提高电子导游机播报的准确性。经ZigBee平台实验,平均识别误差(average recognize error,ARE)明显减小,实验结果表明,该特定算法有效地提高了电子导游系统定位识别播报的精度和可靠性。Electronic guide machine more widely used in various scenic spots, the current electronic guide machine is sometimes have defect that can not recognize the information of the spots accuracy. For solve the problem, the specific algorithms is proposed at the situa- tion of electronic guide machines easily go wrong. The specific algorithms based on the RSSI-based location technology. Using historical information of the user node and using the nearest neighbor node＇ s information to improve the identification accuracy of electronic guide machine. Experiments through using the ZigBee platform show that ARE （average recognition error） obviously reduced, the specific algorithm effectively improves the accuracy and reliability of electronic guide machine.
