Embodiment Construction

[0017] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] The dual-system communication topology structure of the present invention mainly refers to the communication topology structure of the control part, that is, each system includes an interaction module and a control module, and the user inputs instructions through the interaction module, and then the interaction module transmits them to the control module, and then controls The modules then control the shared loads and / or individual loads according to the commands. In this embodiment, the shared load includes an evaporating fan and a condensing fan, and may further include an electric auxiliary heating device. The independent loads are independently controlled by two control modules. The independent loads include two compressors, and may further include two sets of sensors for respectively detecting the working environment para...

Abstract

The invention discloses a dual-system communication topological structure and a dual-system air conditioner. Each system of the dual-system communication topological structure comprises an interactionmodule used for inputting an instruction and a control module used for controlling a shared load according to the instruction, the interaction modules of the two systems are connected with the control module of one system through the communication lines, and the control modules of the two systems are connected with each other through the communication lines. According to the invention, the probability of inconsistent control of the two systems can be greatly reduced when the communication between the two mainboards fails, and the stability and reliability of a unit are improved.

Description

technical field [0001] The invention relates to a dual-system communication topology and a dual-system air conditioner using the dual-system communication topology. Background technique [0002] Many existing equipment or devices use dual systems to meet people's needs at specific times, and the existing dual systems have two independent control systems, each of which has an interaction module and a control module. [0003] Taking the dual-system air conditioner as an example, it is widely used in cars. Due to the limited space in the car and strict requirements on energy consumption, dual-system air conditioners came into being. figure 1 It shows the communication topological structure of the existing two systems. The interactive module is the display board, and the control module is the main board. The dual-system air conditioner relies on the communication between the two systems to know the state parameters of the other party's unit, and realizes the dual-system cooperat...
