Abstract

The invention relates to a multi-connected air conditioning unit and a remote upgrading method thereof. The multi-connected air conditioning unit remote upgrading method comprises the steps that eachmulti-connected air conditioning unit is remotely upgraded through a GPRS module, the GPRS module adopts an election mechanism in a network, and when the GPRS module is elected, a selected zone bit and upgrading packet data are sent to a bus; and when the GPRS module is not elected, whether a selected zone bit or upgrade package data exists on the bus is judged, if so, the election is not participated in, and if not, the election is participated in. When the GPRS module is used for upgrading the air conditioning unit, the elected GPRS module sends a large amount of upgrade package data to thebus; even if the non-elected GPRS module cannot receive the selected flag bit sent by the bus within the preset time, the selected flag bit cannot be received by the unelected GPRS module; when the GPRS modules are not elected, the GPRS modules receive the upgrading package data sent by the bus, once the GPRS modules which are not elected receive the upgrading package data, it is indicated that one GPRS module is elected under the same project, the GPRS modules do not participate in election, and therefore normal upgrading of the air conditioning unit is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-connected air conditioning unit and a remote upgrading method thereof. Background technique [0002] At present, the multi-connected air-conditioning unit has the remote upgrade function of the GPRS module. The GPRS module downloads the upgrade package from the server through the bus and sends the downloaded upgrade package to the bus, so that the air-conditioning units on the same bus can be upgraded. Under one project, there may be more than two GPRS modules. In order to save traffic, GPRS modules have an election mechanism in the network, that is, under the same network, one GPRS module is elected to work, and other GPRS modules are on standby. The conventional processing scheme is that the elected GPRS module sends the selected flag bit flag=1 to the bus every preset time, when other GPRS modules that are not elected receive the selected flag bit sent on the ...
