摘　　要：分析了智能物联网断路器各种空中下载技术的优缺点,构建了云-边-端双层的空中下载升级方案,研究了断路器在升级过程中出现离线的情况下自适应地将多个子设备的固件版本升级到相同固件版本的方案。实际应用表明,设计的方案有助于智能物联网断路器的商业化应用推广。This paper first analyzes the advantages and disadvantages of various over-the-air(OTA)download technologies with respect to intelligent IoT breakers,and then constructs a cloud edge end dual layer OTA upgrade scheme based on the application architecture of intelligent IoT circuit breakers,which generally adopts a single gateway with multiple sub-devices in series combination.In addition,it also studies the scheme of circuit breakers that enables adaptive upgrade of the firmware versions of multiple sub-devices to the same firmware version when offline occurs during the upgrade process.The scheme studied and designed in this paper has been applied in practical IoT circuit breakers,and indicated to facilitate commercial application and promotion of intelligent IoT circuit breakers.
