Abstract

The invention discloses a data synchronization method and device and a multi-split air conditioning system. The method comprises the steps that a synchronous data frame sent by an indoor unit is received, wherein the synchronous data frame comprises the address of the indoor unit and a first address of a wire controller corresponding to the indoor unit, and the synchronous data frame is used for indicating the state of the indoor unit; a second address of the wire controller corresponding to the address of the indoor unit is read from a preset pairing list; if the first address is the same asthe second address, the synchronous data frame is sent to the wire controller. By means of the data synchronization method and device and the multi-split air conditioning system, the technical problemthat communication network data redundancy is caused due to the complex data synchronization process between the indoor unit and the wire controller is solved.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to a data synchronization method and device, and a multi-connected air-conditioning system. Background technique [0002] In the existing multi-connected air-conditioning system, the data synchronization method between the indoor unit and the wire controller is to perform data synchronization through query. However, in a complex communication network, the wire controller needs to regularly send query data frames to inquire whether the indoor unit needs to synchronize data, and then the indoor unit responds to the wire controller and sends synchronization data. Such a complex query response increases communication The amount of data in the network leads to data redundancy in the communication network and poor communication quality. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present inv...
