Air conditioner centralized control method based on indoor unit marshalling and multi-online-air-conditioner system

Abstract

The invention discloses an air conditioner centralized control method based on indoor unit marshalling and a multi-online-air-conditioner system. The method includes the steps that a centralized controller acquires pre-configured coded addresses of outdoor units, pre-configured coded addresses of line controllers and pre-configured coded addresses of indoor units; the acquired coded addresses of the outdoor units are ranked according to the situation that the coded address of each outdoor unit corresponds to a ranking branch line, the acquired coded addresses of the indoor units which are connected with the outdoor units are ranked and then inserted into corresponding ranking branch lines according to the situation that the coded address of each indoor unit corresponds to a column of one ranking branch line, in each ranking branch line, the line controller coded addresses corresponding to the line controllers which are connected with the indoor units are identified, and then a marshalling ranking queue is generated; the indoor units corresponding to the indoor unit coded addresses, meeting a preset address marshalling policy, in the marshalling ranking queue serve as an indoor unit set, and then one or more indoor unit sets are acquired; corresponding function keys are selected for the indoor unit sets. By the application of the air conditioner centralized control method and the multi-online-air-conditioner system, procedures of indoor unit centralized control operation can be simplified, and air conditioner centralized control cost can be lowered.

Description

technical field [0001] The invention relates to air-conditioning control technology, in particular to an air-conditioning centralized control method based on indoor unit grouping and a multi-connected air-conditioning system. Background technique [0002] In the field of central air conditioning, a single outdoor unit can be connected to one or more indoor units through signal lines, and the indoor unit is controlled by the connected wire controller. The outdoor unit, indoor unit and wire controller form an air-conditioning subsystem , In the air-conditioning subsystem, multiple indoor units can share a wired controller. By connecting multiple air-conditioning subsystems together, an air-conditioning system can be formed, that is, a multi-line air-conditioning system. In a multi-connected air conditioning system, there are multiple indoor units, multiple outdoor units, and multiple wired controllers. One wired controller can be connected to one or more indoor units to contr...

Problems solved by technology

In this way, the operation of selecting the indoor units to be controlled from the centralized controller is cumbersome and heavy, requiring professional training to perform relatively skilled operations, which requires high technical requirements for users and increases the cost of centralized air-conditioning control; further, follow-up In the application, if there are changes and adjustments to the scheme of the multi-connected air conditioning system, such as changing settings, moving indoor units, changing outdoor units, adding indoor units, etc., the configuration program of the centralized controller needs to be updated accordingly, and the manufacturer needs to be contacted It takes a long time for technical personnel to solve the problem, which reduces the user's experience of the air-conditioning service
