Abstract
The invention relates to a software online upgrading method for variable-air-volume air conditioning terminal devices, and belongs to the technical field of refrigeration and air conditioning. The software online upgrading method for the variable-air-volume air conditioning terminal devices involves an upgrading device and the plurality of variable-air-volume air conditioning terminal devices connected through a bus, wherein the upgrading device generates files of different types and different versions by processing upgrading code formats, sends a software online upgrading instruction and an upgrading program through the bus, and controls software online upgrading processes of all the variable-air-volume air conditioning terminal devices; each variable-air-volume air conditioning terminal device receives the upgrading instruction, writes the upgrading program in a backup application area, copies a program in the backup application area to an application area when receiving a restart command sent by the upgrading device, and executes a program of a latest version; and the upgrading device judges whether the software upgrading succeeds or not by obtaining software version information of the variable-air-volume air conditioning terminal devices. According to the method, the software online upgrading operation of the variable-air-volume air conditioning terminal devices is simple, the time and the labor cost are saved, and very high reliability and stability are achieved.
