Embodiment Construction

[0027] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] The Internet of Things (IoT) is a network that relies on information carriers such as the Internet and telecommunication networks to enable all ordinary objects that can perform independent functions to realize interconnection. The Internet of Things represents an important development trend that gradually interconnects all aspects of daily life. Unlike earlier wireless devices such as routers, which were limited in number (e.g., one...

Abstract

The invention discloses an automatic upgrading and rollback method and device for Internet-of-things equipment. The method comprises the following steps: acquiring an upgrade package on line so as todownload the upgrade package to a storage space of the Internet-of-things equipment; restoring the upgrade package into an update version required by upgrading in the storage space, and retaining original data required by rollback to an original version; and under the condition that it is judged that upgrading fails, performing rollback of firmware of the Internet-of-things equipment to the original version in the storage space at least based on the reserved original data. According to the OTA upgrading and rollback scheme provided by the invention, the data required for recovering the original version are reserved on the equipment while the version is prepared to be updated, so that the problem of equipment failure caused by the fact that new and old firmware versions cannot be started atthe same time due to an upgrading fault can be effectively solved.

Description

technical field [0001] The present invention relates to an upgrade method, in particular to a method and device for automatic upgrade and rollback of Internet of Things devices. Background technique [0002] With the development of the Internet of Things, the types of smart devices are becoming more and more abundant. In order to reduce maintenance costs and improve user experience, OTA (Over-the-Air, which can be called "online upgrade" or "air upgrade") technology has become a standard configuration in the era of smart IoT. With the popularization of 4G, WiFi and Bluetooth Mesh technologies on IoT upgrade devices, more devices have higher requirements for upgrades. [0003] In order to improve the upgrade efficiency, most of the existing IoT devices use OTA differential upgrade. Once failures such as write failure, differential packet error, and decompression failure occur during the upgrade process, the operating area will be destroyed, the device will be disconnected a...
