Firmware upgrade management method and device and computer-readable storage medium

Abstract

The invention discloses a firmware upgrading management method and device and a computer-readable storage medium. The firmware upgrading management method comprises the following steps: generating a random number and obtaining the whole machine bar code information of an air conditioner; generating dynamic cipher information according to the random number and the whole machine bar code informationof the air conditioner; receiving input cipher information and judging whether the input cipher information is consistent with the dynamic cipher information generated in advance; controlling the main chip of the air conditioner to enter the firmware upgrade mode when the input cipher information coincides with the dynamic cipher information generated in advance; when the input cipher informationis inconsistent with the pre-generated dynamic cipher information, the master chip of the control air conditioner not entering the firmware upgrade mode. The technical scheme of the invention can effectively manage and control the upgrading state of the air conditioner in the terminal market by locking the firmware upgrading function, and avoid abnormal operation of the air conditioner due to wrong upgrading of an external person.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a firmware upgrade management method, device and computer-readable storage medium. Background technique [0002] In recent years, with the improvement of people's consumption level, central air conditioner products have been recognized by more and more consumers. In order to meet the growing needs of consumers, central air conditioner products Other aspects have been greatly improved. After the product is sold to users, if the software has bugs (loopholes) or functions need to be added, it is often necessary to upgrade the software. In order to solve the problem of upgrading the air conditioner, a USB flash drive, SD card, and bus upgrade technology have been developed to send the new burning code to the user or after-sales personnel, and the on-site personnel will save the burned code to the USB flash drive or SD card. Then insert the USB flash drive or SD card int...

[0003] However, in order to ensure the convenience of operation, the upgrade authority is not managed during the upgrade process. Generally, after inserting the USB flash drive or SD card, power on and reset, the main chip will automatically detect the mounting of the USB flash drive or SD card. If a new program is detected and passed a certain verification algorithm, it will be automatically upgraded

Although this method is very convenient, because the programming code can be copied infinitely, after entering the terminal market, the upgrade status of the terminal market is basically out of control. It is necessary to upgrade the software of the units in a specific area due to factors such as scenarios; or the same model, but a customer has developed a custom software for a certain model, but in fact all machines of this type can be upgraded. upgraded

In this way, it is possible to be upgraded by outsiders by mistake or maliciously.

Moreover, if the software version is programmed incorrectly, it will cause the unit to run abnormally.
