摘　　要：针对无线智能音响系统音源声道与音箱手动配置烦琐的问题,文章提出了一种新的自适应配置方法,利用音箱Wi-Fi接收信号强度指示(Received Signal Strength Indicator,RSSI)参数实现无线智能音响系统自动配置。该方法通过采集音箱间的相互发射-接收信号的RSSI参数,组成原始数组,采用数据统计分析方法提取数组的数据特征,对比分析数据特征置信区间的重叠度,辨识各音箱功能;进行音源声道与音箱的自动匹配连接,实现智能音响系统音源声道的自适应配置。实测结果表明,该方法不仅稳定可靠,还能为用户带来更高的人工智能(Artificial Intelligence,AI)服务体验。In order to solve the problem of having difficulty in manual configuration between the audio source channel and speaker of the wireless intelligent audio system,this paper proposes a new adaptive configuration method,which uses the speaker Wi-Fi received signal strength indicator(RSSI)parameters to realize the automatic configuration of the wireless intelligent audio system.The proposed method creates the initial data arrays by collecting the RSSI parameters of the mutual transmit-receiving signals among the wireless speakers,and extracts the data features by statistical analysis methods.The proposed method recognizes the speaker functions by comparing the overlaps of the confidence intervals of the data features.The audio source channels and the speakers can be automatically linked respectively,and the adaptive configuration of the wireless intelligent audio system is achieved.The measured results show that the proposed method is not only stable and reliable,but also can provide users with a higher AI level service satisfaction experience.
