Abstract

The invention relates to a multi-connected cluster system unit upgrading method and device. The method comprises the following steps: acquiring equipment information of each piece of multi-connected equipment in a multi-connected machine group system; determining the multi-split equipment to be upgraded according to the acquired equipment information of the multi-split equipment; generating upgrading program packages according to the determined equipment information of the multi-split equipment needing to be upgraded, wherein the upgrading program packages is in one-to-one correspondence withthe multi-split equipment needing to be upgraded and comprising program data and equipment information; sending an upgrading instruction to each multi-split device through the CAN bus, so that all themulti-split devices stop working; generating response information and upgraded according to the upgrading instruction; and obtaining upgrading response information sent by the multi-split equipment,and sending all upgrading program packages according to the upgrading response information, so the multi-split equipment obtains the upgrading program package corresponding to the multi-split equipment according to the equipment information and carries out synchronous upgrading.

Description

technical field [0001] The invention relates to the technical field of local area network communication, in particular to a method for upgrading units of a multi-connected group system. Background technique [0002] At present, multi-connected air conditioners are widely used in commercial places such as shopping malls, gymnasiums, and office buildings. Due to their large capacity and flexible configuration, they are deeply trusted by users. However, due to many factors such as complex systems, many functions, and uncertain working conditions, the system sometimes run unstable or [0003] The operation is abnormal. At this time, the control system needs to be optimized and upgraded. Since the types of multi-connected devices are usually external units, internal units, drive modules, etc., equipment software upgrades may involve, and the usual software upgrade methods are: [0004] 1. Replace the motherboard or chip: [0005] The after-sales personnel directly disassemble ...
