Abstract

The invention discloses a multi-split air conditioning system which comprises an outdoor unit, an indoor unit and a wire controller. The outdoor unit and the indoor unit are in communication connection through a first network layer, the indoor unit and the wire controller are in communication connection through a second network layer, the first network layer and the second network layer form a communication network together, and the communication network carries out communication through a CAN bus protocol. According to the multi-split air conditioning system, the layered communication network used for carrying out data transmission among various devices in the multi-split system on the basis of a CAN communication mode is built, all nodes formed by the outdoor unit, the indoor unit and other devices in the network are equal, all the nodes can send data through the communication network at any time when the network is idle, communication efficiency is high, and instantaneity is high. The communication network is layered, good in expansibility and flexible in networking and facilitates centralized monitoring and control of the multi-split air conditioning system.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a multi-connected air conditioning system. Background technique [0002] In the air-conditioning system, the multi-line communication network is the most complex communication system in the air-conditioning system. It has many network equipment nodes, a large amount of data interaction, long communication distance, and high data timeliness and accuracy requirements. higher requirements. In the traditional technology, most of the multi-connected communication networks are established based on the RS-485 communication method, and the network adopts a master-slave structure, that is, the master control machine cyclically calls the slave machines, and the slave machines respond to the master control machine. This has caused the traditional The timeliness of important data response in the multi-connected air-conditioning system is poor, and the communication efficiency is low. Conte...
