Internet of Things equipment firmware remote updating method, device and system

Abstract

The invention provides an Internet of Things equipment firmware remote updating method, device and system. The method comprises the steps that a cloud server receives new version firmware and an updating request through a network, and carries out the version verification of current version firmware; after the verification is passed, the new version firmware is transmitted to the Internet of Thingsdevice, version mark information is set for the new version firmware, and the version mark information is stored in a database for the Internet of Things device to inquire; the Internet of Things device receives the new version firmware of the cloud server and verifies the information of the new version firmware; when the updating condition is met, version updating is started to be executed; if an abnormal updating condition occurs in the middle of version updating, version rollback operation is executed, and the current version firmware is recovered; if not, the current version is fixedly upgraded to the new version firmware; and through a hardware multi-column storage system structure and a software rollback processing mechanism, firmware can be ensured to be safely updated under any condition, Internet of Things resource use is optimized, and bandwidth constraint and allocation are adapted.

Description

technical field [0001] The present disclosure relates to a method, device and system for remotely updating firmware of an Internet of Things device. Background technique [0002] With the development of the Internet and information technology, Internet of Things (IoT) technology and devices are being applied and deployed in many fields at a rapid pace. It is estimated that about 41 billion devices will be online in 2027. The Internet of Things, with its vast ecosystem of connected devices, is deployed in many environments, bringing complexities associated with the update process. There are many reasons to update firmware after a product has shipped, including fixing bugs, adding new features, or improving security. At present, this task is generally accomplished by adopting an update mechanism. However, once IoT devices are deployed, due to the long life cycle of IoT devices, especially when there are a large number of devices, they are deployed in remote or inaccessible un...

AI Technical Summary

Problems solved by technology

At present, few IoT device development companies have IoT hardware, software, connectivity, and cloud ecosystems, and lack the ability and overall solutions to independently handle OTA firmware updates and manage remote devices, while public IoT platforms such as Alibaba Cloud, Baidu Cloud, etc. These large Internet companies focus mainly on platforms and software, and generally do not involve IoT hardware and firmware. Although they also launch some IoT OTA functions, in fact they only provide complete, reliable and secure updates. A small number of functions are required, which cannot fully meet the firmware update needs of most IoT devices

Based on the above reasons, in order to ensure the deployment, update and use of IoT devices in a long life cycle, and avoid expensive, time-consuming and laborious recalls and on-site services, it is urgent to find new methods and solutions that can comprehensively improve the remote update of IoT device firmware.
