Address allocation method and device for air conditioning equipment

Abstract

The invention discloses an address allocation method and device for air conditioning equipment. The method comprises the steps that a main machine in an air conditioning unit allocates instructions to broadcast addresses a slave machine unit, wherein multiple slave machines included in the slave machine unit and the main machine belong to a same communication network; the main machine receives identity information returned by the first slave machine according to the address allocation instructions, wherein the first slave machine is any one slave machine in the slave machine unit; the main machine generates an address to be allocated to the first slave machine according to the returned identity information; the main machine sends the address to the corresponding first slave machine. According to the address allocation method and device for the air conditioning equipment, the technical problem that in the prior art, the installation efficiency is low due to the fact that when RS484 buses are adopted to perform data communication among different equipment in the air conditioning unit, a dip switch needs to be manually arranged in the engineering installation process of the air conditioning unit is solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an address allocation method and device for air conditioners. Background technique [0002] In the current air-conditioning control technology, when the RS485 bus is used for data communication between different equipment of the air-conditioning unit, the equipment uses a fixed communication address that has been assigned at the factory. When multiple devices of the same type are connected to the RS485 bus (such as multiple wire controllers as slaves or multiple air-conditioning internal units), then additional devices, such as dial switches, are required to distinguish between devices of the same type. individual devices. However, additional components will lead to an increase in product cost. At the same time, during the engineering installation process of the air conditioning unit, it is necessary to manually set the additional components (such as setting the...
