Problems solved by technology

[0003] But, the shortcoming that the relevant technology exists is, every time when inquiring, the slave all sends its own status information to the master, so that the more devices connected on the communication bus, the more communication data content, and one polling (that is, the master completes the inquiry) The time of each slave) will become very long, so that the state of the slave cannot be refreshed in time, and there will be a large amount of redundant data, and the overall communication efficiency is very low

Abstract

The invention discloses an air conditioning system and a communication method thereof. The method comprises the following steps that an outdoor machine sends a query command to each indoor machine, and each indoor machine judges the type of the received query command, wherein the types of the query commands comprise a mandatory query command and a common query command; after receiving the mandatory query command, each indoor machine generates a long message, and returns the long message to the outdoor machine; and after receiving the common query command, each indoor machine judges whether the state information of the indoor machine changes, and if there is no change, generates a short message and returns the short message to the outdoor machine; and therefore, each polling time is reduced, the communication efficiency and the communication effectiveness are promoted, the outdoor machine can timely update the data, and the redundant data during the communication process can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a communication method for an air conditioner system and an air conditioner system. Background technique [0002] In related technologies, there is only one master on the communication bus, and the rest of the devices on the communication bus are slaves. During the working process, the master often needs to continuously collect slave information to refresh data in real time. [0003] But, the shortcoming that the relevant technology exists is, every time when inquiring, the slave all sends its own status information to the master, so that the more devices connected on the communication bus, the more communication data content, and one polling (that is, the master completes the inquiry) The time of each slave) will become very long, so that the state of the slave cannot be refreshed in time, and there will be a large amount of redundant data, and the overall communication...
