摘　　要：本文针对智能产品配网绑定耗时偏长又极难排查的行业性问题,对业界应用最广的"Soft AP"和"快联"机制进行细致分析后,提出了通过智能手机终端、智能产品终端、智能产品服务后台联合抓包来定位配网绑定时效问题的方法.将该方法应用于智能热水器、智能空调等产品后,成功定位到影响配网绑定时效的关键环节和因素.以此为依据的优化措施有效降低了产品配网绑定的耗时,显著提升了用户体验.In this study, we mainly aim at the problem that Wi-Fi provisioning of the smart goods in home always takes too much time but hard to troubleshoot. Based on detailed study of “Soft AP” and “Simple Config” which are most commonly used for WiFi provisioning of smart goods, we proposed a new research method in which packet capture is involved among the cell phones, smart goods, and corresponding servers to locate the issues. By applying this method to research time-effectiveness of WiFi provisioning for smart water heater and smart air conditioner, we successfully located the key segments and factors that impact the time-effectiveness. The optimization measures based on the research result have reduced the time consumed on WiFi provisioning a lot, and improved the user experience greatly.
