Embodiment Construction

[0034] The present invention takes the multi-line and multi-line drive components (also called variable frequency drive components) in the air-conditioning system as the connecting components that may need to be upgraded in the external machine as a specific embodiment, to illustrate the principle and implementation of the present invention in detail with the accompanying drawings example.

[0035] Such as figure 1 , figure 2 As shown, there are mainly two network structures of the air conditioning system of the present invention (multi-connection in this embodiment). The first is that the network of the air-conditioning system includes a first network composed of each outdoor machine and each internal machine in a connection system, and a second network composed of each outdoor machine in the connection system and its driving components. The second is that the air conditioning system network includes a first network composed of each external machine and each internal machine in...

Abstract

The invention discloses a software upgrading method of an air conditioning system. The method comprises the following steps that: an upgrading terminal loaded with upgrading program data is connectedwith the network of the air conditioning system, and the air conditioning system enters an upgrading state; the upgrading terminal acquires the identification data of a to-be-upgraded part in the airconditioning system; whether at least one piece of upgrading program data is uniquely matched with the to-be-upgraded part or not is judged, if at least one piece of upgrading program data is uniquelymatched with the to-be-upgraded part, the upgrading terminal sequentially broadcasts each piece of upgrading program data to each outdoor unit through a bus, and the upgrading program data are forwarded to the connecting parts of the outdoor units through outdoor unit protocol conversion; the to-be-upgraded part judges whether the upgrading program data are upgrading program data matched with theto-be-upgraded part, if the upgrading program data are the upgrading program data matched with the to-be-upgraded part, upgrading is conducted, and response data of successful upgrading are sent to the upgrading terminal through outdoor unit protocol conversion; and if the corresponding to-be-upgraded part is successfully upgraded, the upgrading terminal informs the air conditioning system of quitting the upgrading state. By means of the method, the multiple outdoor units of a multi-split air conditioner can be upgraded, and the upgrading process of operators is simplified.

Description

Technical field [0001] The invention relates to a software upgrade method of an air conditioning system, in particular to a single-system or multi-system multi-line software upgrade method. Background technique [0002] At present, multi-line air conditioners are widely used in commercial places such as shopping malls, stadiums, and office buildings. They are trusted by users due to their large capacity and flexible configuration. However, due to many factors such as complicated multi-line systems, more functions, and uncertain working conditions, The system sometimes runs unstable or runs abnormally. Usually the external machine and its internal connecting components (such as variable frequency drive components, etc.) form an independent control system and are interrelated. At this time, if it is necessary to upgrade the software of the variable frequency drive and other connecting components, the existing operation methods are as follows: [0003] 1. Replace the main board of th...
