Problems solved by technology
[0003] During the project implementation or the use of the multi-connected air-conditioning system, if there is a problem with the program of the slave unit, it is generally necessary to open the shell of each slave unit one by one to upgrade the program loaded on the electric control board, which is time-consuming and laborious; The program can be upgraded by means of bus communication, but because the bus transmission rate is generally relatively slow, when there are many slave machines to be upgraded, it still takes a long time to upgrade one by one
[0004] The program upgrade scheme for the slave units of the above-mentioned multi-connected air-conditioning system is too low in upgrade efficiency, which brings a bad experience to users

The present invention provides a program upgrading method and a program upgrading device for a multi-connected air-conditioning system, a master, a slave and a multi-connected air-conditioning system of the multi-connected air-conditioning system, wherein the program upgrading method for the master of the multi-connected air-conditioning system includes: The data of the program is divided into multiple pieces of program data; each piece of program data is broadcast and delivered to each of the multiple slaves in the multi-line air conditioning system; the preset slave list is broadcast to each slave, and the preset The slave machine list is set to be used for each slave machine to determine whether to perform program upgrade according to each segment of program data, wherein the preset slave machine list is expressed in the form of a mask. Through the technical solution of the present invention, the upgrade efficiency can be effectively improved, the upgrade cost can be saved, and user experience can be improved.
Description
technical field [0001] The present invention relates to the technical field of multi-connected air conditioners, in particular, to a program upgrading method for a multi-connected air-conditioning system, a program upgrading device for a multi-connected air-conditioning system, a master of a multi-connected air-conditioning system, a slave of a multi-connected air-conditioning system, and a multi-connected air conditioner Air Conditioning System. Background technique [0002] The multi-connected air-conditioning system is composed of multiple air-conditioning subsystems, which can realize the free combination of multiple outdoor units and multiple indoor units, up to 64 or more indoor units (hereinafter referred to as slave units). [0003] During the project implementation or the use of the multi-connected air-conditioning system, if there is a problem with the program of the slave unit, it is generally necessary to open the shell of each slave unit one by one to upgrade th...
