Abstract

The present application provides a program upgrade file identification method, a multi-split air-conditioning system and a readable storage media. When the program upgrade files pass the test and inspection, the files can be used for the operation of the unit. By encrypting the group type, it is possible to make different group types correspond to different first encrypted strings. If there is a program upgrade file that has been altered or tampered with and the source of the program upgrade file is unknown and the program upgrade file is misused, the new program upgrade file obtained by encrypting the program upgrade file by the program upgrade file identification method will not be consistent with the corresponding unit type, and will not be burned into the corresponding unit controllerat this time. When the encrypted new program upgrade file corresponds to the unit type of the unit to be upgraded, the correct and legal program upgrade file can be burned into the corresponding unitcontroller to ensure the normal operation of the unit program upgrade.

Description

technical field [0001] The present application relates to the technical field of air conditioners, in particular to a program upgrade file identification method, multi-connection and readable storage media. Background technique [0002] With the rapid development of society and the continuous improvement of people's quality of life, the use of multiple online devices is becoming more and more popular. The air-conditioning system is the main component in the building, including various types of air-conditioning units, such as multiple units, screw units, centrifugal units, etc. Various units have the function of changing the working state according to the input files. These program files need to conform to their corresponding unit types before they can be upgraded and debugged. In the field of multi-unit air conditioners, with the continuous application of multi-unit internal and external unit programs in after-sales processing, due to the large number of indoor and outdoor ...
