System and method for centralized control of central air conditioner based on graphical interface

Abstract

The invention discloses a system and a method for the centralized control of a central air conditioner based on a graphical interface. The system comprises a centralized controller, master control boards and a mobile terminal, wherein the master control boards are respectively mounted in all air conditioning units of the central air conditioner; the centralized controller is used for respectively acquiring status parameters of all the air conditioning units from all the master control boards through serial buses; the mobile terminal is used for acquiring the bus addresses and status parameters of all the air conditioning units from the centralized controller in a wireless manner; the mobile terminal is further used for displaying a real-scene graph similar to a mounted place of each air conditioning unit of the central air conditioner, displaying the graph of the related air conditioning unit corresponding to the real-scene graph and displaying the name of the related air conditioning unit and status parameters of the related air conditioning unit with a bus address associated with the related air conditioning unit name corresponding to the graph of the related air conditioning unit. According to the system and the method, the central air conditioner is controlled based on the graphical interface by using the mobile terminal, so that the control manner is flexible and convenient, and the needs of users can be better met.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a graphical interface-based central air-conditioning centralized control system and control method. Background technique [0002] With the development of social economy, central air conditioners are becoming more and more popular, and more and more home users choose to install central air conditioners. In the field of central air-conditioning, there are many indoor air-conditioning units installed and the area of ​​the house is large, which brings many changes to the one-by-one control of air-conditioning; therefore, centralized control is usually used to solve the above problems. [0003] The central air conditioner is mainly composed of an indoor unit, a wire controller and an outdoor unit. Usually, one outdoor unit is connected to multiple indoor units, and each indoor unit is connected to a wire controller. And the indoor unit and the outdoor unit are controlled in linkage. ...

AI Technical Summary

Problems solved by technology

[0008] The centralized controller is usually installed in a fixed position, and it is installed in a buried wall and cannot be moved. The user needs to go to the fixed position of the centralized controller to control the central air conditioner; moreover, the centralized controller adopts mechanical keys and segment display liquid crystals. Complicated, users need to be trained before using

[0009] Therefore, the central air-conditioning control system based on the existing centralized controller has a single control method and is inconvenient, and cannot well meet the needs of users. Therefore, it is necessary to provide a more flexible and convenient central air-conditioning centralized control system and method to solve this problem
