A device upgrade method and device

Abstract

A device upgrade method and device are disclosed, the method comprising: an IOT gateway acquires an upgrade request, and the upgrade request includes a first expected version number of an upgrade package; The expected version number of at least one device is updated, and at least one update result including the first expected version number after the update is recorded on the block chain local ledger; the IOT gateway determines the device to be upgraded through the first expected version number; And sending an upgrade task to the device to be upgraded, so that the device to be upgraded updates its own version number according to the first expected version number. This method, based on the block chain consensus mechanism and distributed ledger function, determines the device to be upgraded through the updated expected version number, so that the device information of these devices is not limited to a certain device, and avoids when a certain network element device fails. , affects the equipment upgrade of the entire network, and this method improves the robustness of the equipment upgrade system.

Description

technical field [0001] This application relates to the field of block chains, and in particular to a method and device for upgrading equipment. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. The Internet of things (IoT) is the Internet where things are connected. It includes two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; exchange and communication. Generally, "items" can be collectively referred to as IOT devices. [0003] IOT devices often face the need for upgrades (including device firmware, software packages on devices, etc.) The realization of innovation. Also, in order to protect IOT devices from attacks and damage, they need to be upgraded to the latest firmware. [0004] Currently, IoT device upg...

AI Technical Summary

Problems solved by technology

[0019] In the above-mentioned IOT device upgrade process, the IOT platform is the center of the entire IOT system. Once a failure occurs, the IOT platform may be affected, which may lead to the interruption of the IOT device upgrade business.

The IOT system is usually a large-scale system (including hundreds of millions of IOT devices), which makes it more difficult to ensure the robustness of the IOT device upgrade system (Robustness)
