Automatic addressing method for air conditioning system and air conditioning controller

Abstract

The invention discloses an automatic addressing method for an air conditioning system. A first air conditioning serves as a master machine and the other air conditionings serve as slave machines. The method comprises the following steps that: the master machine sends broadcast information to notify the slave machines to enter an automatic addressing mode and the slave machines restore the addresses per se to initial addresses; the master machine transmits the addresses to be allocated, wherein the addresses to be allocated add one automatically, the slave machines receive the addresses to be allocated and transmit response information which comprises the allocated addresses to be competed by the slave machines and the MAC addresses of the slave machines; if receiving the response information from the slave machines, the master machine transmits the address acknowledgement information which comprises the allocated addresses successfully competed by the slave machines and the MAC addresses of the slave machines; and after the addressing of all controllers is finished, the master machine transmits the broadcast information to notify the slave machines to finish the automatic addressing state and the master machine and the slave machines quit the automatic addressing state. The air conditioning system can be simply and easily subjected to automatic addressing by the method without easy error. The invention also discloses an air conditioning controller.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to an automatic addressing method for an air conditioning system and an air conditioning controller. Background technique [0002] The current VRV / VRF (Varied Refrigerant Volume / Variable Refrigerant Flow, variable refrigerant flow) air conditioning system is similar to the split air conditioning unit in terms of system structure. A single refrigeration system generally uses one outdoor unit to connect to a group of indoor units, or multiple One outdoor unit is connected in parallel with more indoor units to form a larger air conditioning system. In practical applications, multiple refrigeration systems can also be interconnected through their own control network to form a larger air-conditioning control system. However, a large amount of control information and status information need to be transmitted between each unit in the system. In order to ensure that info...
