Abstract

The embodiment of the invention relates to a method and system for recovering Internet of Things terminal firmware. The method comprises the following steps: firstly, storing backup firmware in an Internet of Things terminal for firmware of the Internet of Things terminal; then, after the Internet of Things terminal is powered on and started, enabling a program to be guided by the Internet of Things terminal to detect whether firmware is abnormal or not, operating backup firmware when the firmware is abnormal, publishing firmware abnormal information, a terminal serial number with the abnormalfirmware and a firmware version number through a first Internet of Things communication module, and meanwhile subscribing a firmware upgrading theme; correspondingly binding a firmware downloading task by the Internet of Things server according to the received firmware exception information, the terminal serial number of the firmware exception and the firmware version number, and correspondinglypushing an upgrading task message; receiving and utilizing the upgrading task message by the backup firmware, and downloading a corresponding firmware upgrading packet from the Internet of Things server; finally, judging whether the firmware upgrade package is successfully downloaded or not; if so, installing the firmware upgrade package, and otherwise, continuing downloading. Firmware recovery can be simplified via the method, and recovery can be automatically carried out.

Description

technical field [0001] The embodiments of the present invention relate to the field of the Internet of Things, and in particular to a system and method for restoring firmware of an Internet of Things terminal. Background technique [0002] Due to the huge advantages of the fifth-generation mobile communication (5G) in low latency, ultra-low power consumption, and multi-terminal compatibility, with the commercialization and popularization of 5G, more industries contained in it will gradually emerge. Internet of Things (IOT) terminals can obtain a low-latency, ultra-low-power consumption network environment through 5G, and can realize the Internet of Everything. [0003] During the use of Internet of Things terminals such as POS machines, they usually need to be returned to the factory for repairs due to abnormal or missing firmware during firmware running or upgrading. In order to avoid this type of returning to the factory for maintenance, the prior art provides a networked...
