All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is noted that the terms "comprises" and "comprising," and any variations thereof, as used in the embodiments of the present invention, are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or apparatus that comprises a list of steps or elements is not limited to those listed but may alternatively include other steps or elements not listed or inherent to such process, method, product, or apparatus. Furthermore, the terms "first," "second," and "third," etc. are used to distinguish between different objects and are not used to describe a particular order.

Specifically, the internet of things terminal can be each smart home in a family, each smart home in the family is connected together through the internet of things, and a gateway in the family performs mutual coupling and data transmission through intermediate devices such as an access point. After a certain access point fails and cannot work continuously, the gateway performs hot backup on data on the failed access point to the second access point, and simultaneously transfers the intelligent home terminal mounted on the failed access point to the third access point for mounting, so that the normal operation of the whole intelligent home internet of things is ensured, and double safety guarantee is provided for the safe operation of the whole internet of things.
