Embodiment

[0028] A method for detecting and processing a central air conditioner address conflict in this embodiment, such as figure 1 shown, including the following steps:

[0029] A1: Establish an indoor unit information database; the indoor unit information database includes the installation location information and usage frequency of the indoor unit. The indoor unit information base also includes the indoor unit address. Centrally storing various information of the indoor unit in the information base can facilitate the outdoor unit to read the information of the indoor unit and improve work efficiency; the usage frequency is determined according to the historical power consumption of the indoor unit. The larger the historical power consumption, the higher the usage frequency of the indoor unit, and the higher the priority.

[0030] A2: Extract the indoor unit information from the information database and establish the priority of each indoor unit; determine the priority according ...

Abstract

The invention discloses a method for detecting and processing address conflicts of central air conditioners. In order to overcome the problem that address conflicts cannot be automatically processed in the prior art, the method comprises the following steps: 1, establishing an indoor unit information base; 2, indoor unit information is extracted from the information base, and the priority of each indoor unit is established; 3, the addresses of the indoor units are sequentially arranged according to the priority from low to high, and an address string is formed; 4, starting from the first address in the address string, detecting whether other indoor units with the same address exist or not, and if yes, changing the address of the indoor unit with the low priority into a new address; and if not, continuing to detect the next address in the address string until all the addresses are detected. New addresses can be automatically allocated to the indoor units with address conflicts so as to solve the problem of address conflicts; the empty address mark and the empty address set are utilized to prevent repeated allocation of empty addresses, and the system reliability is improved.

Description

technical field [0001] The invention relates to the field of central air conditioner address conflict, in particular to a detection and processing method for central air conditioner address conflict. Background technique [0002] At present, many manufacturers are producing multi-connected air conditioners, and there are more and more applications of multi-connected air-conditioning units. However, due to the large system of multi-connected air-conditioning units and the large number of indoor units, once the address settings of the indoor units are repeated, the outdoor unit will not be able to control the indoor units with the same address, which will affect the operation and use of the air conditioner. However, the current system can only check and alarm the communication errors between the indoor unit and the outdoor unit, but cannot check whether the addresses of the indoor unit conflict. To find the indoor units with duplicate addresses, the current method is to check...
