Abstract

The invention discloses a multi-split system and a networking method thereof. The multi-split system comprises an outdoor unit, a plurality of indoor units and an power line carrier communication module, wherein the outdoor unit comprises an outdoor unit main control board; each indoor unit is connected with the outdoor unit through a refrigerant pipeline, and comprises an indoor unit main control board; the power line carrier communication module comprises a first carrier communication unit and a plurality of second carrier communication units; the first carrier communication unit is connected with the outdoor unit main control board; the second carrier communication units are connected with the indoor unit main control boards one to one; and the first carrier communication unit establishes carrier communication connection with the second carrier communication units through the refrigerant pipelines, so that the outdoor unit can communicate with each indoor unit. The multi-split system realizes the effect of communication between the outdoor unit and the indoor units by taking the refrigerant pipelines as physical information channels, and both the reliability and the stability are relatively high.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a multi-connection system and a networking method for the multi-connection system. Background technique [0002] At present, the central air-conditioning power carrier technology is all based on power line communication, that is, data transmission is performed directly on the power supply circuit (380VAC or 220VAC) of the central air-conditioning. [0003] Although the power carrier technology has made great progress in recent years, the reliability and stability of the power carrier have been greatly improved by introducing OFDM (Orthogonal Frequency Division Multiplexing) technology, but its stability still fails to reach the existing RS485, The level of wired communication such as CAN bus. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the...
