And the communication module 20 is used for realizing networking of the outdoor unit B.
Server
Referring to fig. 1, the multi-split air conditioner of the present application further includes a server 30, which is in indirect communication with the communication module 20, for example, through a communication base station.
In the present application, the server 30 is used to store software of each indoor unit An, the main control board 10, and the communication module 20.
The software may be current software of each indoor unit An, the main control board 10 and the communication module 20, and some, some or all of the upgrade software of each indoor unit An, the main control board 10 and the communication module 20 to be upgraded.
The process of the server 30 acquiring the current software is as follows.
After the outdoor unit B is networked through the communication module 20, the communication module 20 acquires the main control board 10 and current software of all indoor units An connected to the multi-split system through a communication bus; then, the communication module 20 sends the current software of itself, the acquired current versions of the main control board 10 and the indoor units An to the server 30, and stores the current software and the acquired current versions in the server 30.
The required upgrade software will also be stored in the server 30.
Some, some or all of the upgrade software in each indoor unit An, the main control board 10 and the communication module 20 needs to be associated with the current software, so as to determine which one or more of each indoor unit An, the main control board 10 and the communication module 20 has the upgrade software, so as to perform upgrade after the upgrade is confirmed.
It should be noted that the software referred to in this application includes a software version number and a software file, and the software version number is associated with the software file.
The server 30 determines whether the upgrade software exists, sends an upgrade instruction to the communication module 20 if the upgrade software exists, and feeds back the upgrade instruction to a confirmation instruction that the server 30 can upgrade when the communication module 20 determines that the upgrade instruction is valid.
After receiving the confirmation instruction that the upgrade is possible sent by the communication module 30, the server 30 sends the matched upgrade software to the communication module 20.
After the communication module 20 receives the upgrade software, it determines whether the upgrade software is of itself or each indoor unit An or the main control board 10, so as to upgrade each indoor unit An, the main control board 10 or the communication module 20.
The communication module 20 belongs to a part of the outdoor unit B, which facilitates networking and upgrading of the outdoor unit B, does not require other independent devices except the server 30 except an air conditioner, and is convenient to maintain in terms of hardware.

The air conditioner user decides whether to upgrade or not through manual selection by checking the upgrade content and the upgrade reason.
For example, clicking the "upgrade" button on the interface of the server 30 selects an immediate upgrade, i.e., a manual license to download the upgraded software from the server 30; clicking the "not upgrade" button on the server 30 interface selects not to upgrade for the moment,
the manual decision avoids blind upgrade, improves upgrade flexibility and user experience, and for example, a user currently uses the multi-split air conditioner and does not want to stop to upgrade.
It should be noted that, when the multi-split air conditioner is in a shutdown state, the "upgrade" button may be manually selected or automatic upgrade may be implemented, or the air conditioner user may select to make an appointment for automatic upgrade when the multi-split air conditioner is shutdown next time.
And if the air conditioner user with the second management authority selects the 'upgrading' key to select immediate upgrading, starting an upgrading program by the multi-split air conditioner.
After entering the upgrade procedure, before upgrading the current software of the main control board 10 or the communication module 20 of each indoor unit An and the outdoor unit B, the upgrade software received by the communication module 20 needs to be judged.
As follows, the upgrade of the communication module 20 and the upgrade of the main control board 10 of each indoor unit An or outdoor unit B will be described separately.
