Household appliance control device, control method and centralized control system

Abstract

The invention discloses a household appliance control device, a household appliance control method and a centralized control system, which relate to the field of household appliances, realize the control of an air conditioner monitoring system on a large number of indoor units, and save the cost. The household appliance control method is characterized by comprising a controller, a first 485 communication module and a second 485 communication module, wherein the first 485 communication module is connected with a household electrical appliance through a first 485 bus and is used for acquiring actual operation parameters of the household electrical appliance and transmitting the actual operation parameters to the controller; the controller is used for analyzing the actual operation parametersaccording to a preset format, determining whether the actual operation parameters are abnormal or not to obtain an abnormal result, packaging the analyzed actual operation parameters and the abnormalresult by adopting a target format and transmitting the packaged data to the second 485 communication module, and the target format is a Modbus format; and the second 485 communication module is connected with monitoring equipment through a second 485 bus and is used for transmitting the packaged data to the monitoring equipment.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a control device, a control method and a centralized control system for household appliances. Background technique [0002] At present, when the Modbus protocol is applied to the air-conditioning centralized control system, the number of internal units controlled is small, which makes the current air-conditioning centralized control system unable to meet the needs of the air-conditioning market. When the air-conditioning centralized control system is applied to a commercial building, if the number of indoor units in the commercial building is large, multiple air-conditioning monitoring systems need to be used, which will increase costs and waste manpower and material resources. Contents of the invention [0003] The invention provides a control device, a control method, and a centralized control system for household appliances, which realize the control of a large number of ...
