Problems solved by technology

For example: A manufacturer produces two kinds of children's story machines at the same time. The two children's story machines are only different in appearance and sound. One has a boy's appearance and a boy's voice, and the other has a girl's appearance. As a result, the male-shaped equipment emits female voices, and it is difficult to repair the products that have been sold remotely, and they can only be returned to the factory, resulting in increased maintenance costs

Embodiment Construction

[0041] figure 1 A schematic flow chart of the server and embedded device upgrade method for OTA upgrade is given in this embodiment, the flow chart will be used for the server upgrade method for OTA upgrade and the embedded device upgrade method for OTA upgrade Together, it intuitively reflects the process of mandatory OTA firmware upgrades for embedded devices.

[0042] S0, create and import an Excel table: save the Mac addresses of all embedded devices that need to be upgraded, the product ID of the target firmware that needs to be upgraded to, the version number of the target firmware, and the firmware type (mcu firmware / wifi firmware) Into the Excel table, one record per line; then import the above Excel table on the cloud platform's mandatory OTA upgrade page. Step S0 is the preparatory work before upgrading.

[0043]S1. The server regularly polls the embedded devices in the above Excel table that require mandatory OTA firmware upgrades to check whether any embedded dev...

Abstract

The invention discloses a server for OTA upgrading and an embedded device upgrading method and device. The method comprises the following steps: a server sends a forced OTA firmware upgrading instruction to each online embedded device according to a list, and the embedded device sends a version updating detection data packet to the server, the server returns a firmware information data packet to the corresponding embedded device, the embedded device receives the firmware fragments, and after upgrading is completed, the server deletes the device from the list. The server upgrading device comprises an OTA firmware upgrading instruction sending module; a firmware information data packet sending module; an upgrade instruction sending module; and a device removal module. The embedded device upgrading device comprises a version updating detection data packet sending module, a firmware fragmentation receiving module; and an upgrade module. The traditional OTA firmware upgrading process is bypassed, the problem of firmware upgrading errors caused by human negligence can be effectively solved, and the maintenance cost is reduced.

Description

technical field [0001] This application relates to the field of the Internet of Things, in particular to OTA firmware upgrade technology. Background technique [0002] OTA firmware upgrade means that the terminal obtains the firmware version through wireless download and upgrades the terminal firmware. The traditional OTA firmware upgrade technology is mainly used in large embedded devices such as mobile phones and tablets. [0003] With the rise of the Internet of Things industry, more and more low-power embedded devices are emerging, and these devices are also facing the need for OTA firmware upgrades. At present, the OTA firmware upgrade of small embedded devices is implemented by the device manufacturer, and most of them divide and manage the firmware according to the product type, and judge whether it needs to be upgraded according to the firmware version number. For example: A type air conditioner (or A type TV) and B type air conditioner (or B type TV) owned by a ce...
