Air-conditioner repeater, air-conditioner system and a control method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner control systems face challenges in securely controlling multiple air conditioners with a single remote controller, especially when obstacles are present, and current wireless communication methods compromise security.
Innovation Solution
An air conditioner repeater system that connects to a remote controller via a cable to generate pairing information, performs secure Bluetooth pairing, and transfers wireless signals to the air conditioner, allowing convenient wireless control while enhancing security by managing pairing information and releasing connections as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless communication method (other than IR) is used to control air conditioners, then user convenience is improved by eliminating the need to move to positions without obstacles, but security is worsened due to poor security in wireless communication connection processes
Solution Approach 1:
The patent introduces a repeater as an intermediary device between the remote controller and air conditioner. The repeater receives wireless signals from the remote controller, establishes a secure wired connection to the air conditioner, and transmits control signals through this secure channel. This mediator approach allows wireless convenience while maintaining wired security for the critical control path.
Solution Approach 2:
The system is segmented into three distinct components: the remote controller (wireless interface), the repeater (conversion hub), and the air conditioner (controlled device). This segmentation allows each component to specialize - the remote controller provides wireless convenience, the repeater handles security through wired connections, and the air conditioner receives reliable control signals, resolving the contradiction between wireless ease of operation and security.
2Ease of operation
If a single remote controller is used to control multiple air conditioners, then management convenience is improved, but the complexity of secure pairing and connection management increases
Solution Approach 1:
The repeater is designed as a universal device that can pair with multiple remote controllers and control multiple air conditioners simultaneously. It maintains separate pairing information for different remote controllers and routes signals appropriately, allowing a single remote controller to effectively manage multiple air conditioners through the same repeater infrastructure.
Solution Approach 2:
The system implements feedback mechanisms where the repeater monitors connection status, pairing states, and signal transmission success. When a remote controller connects, the repeater provides feedback about existing pairings and manages the pairing process automatically, reducing the complexity burden on the user while maintaining comprehensive control over multiple devices.

AI summary
An air conditioner controlling method of an air conditioner repeater is provided. The method includes based on a remote controller being connected to the air conditioner repeater via a cable, generating pairing information, transferring the generated pairing information to the remote controller via the cable, based on a response message for the pairing information being received from the remote controller via the cable, performing pairing with the remote controller, and based on the wired connection with the remote controller is released and an air conditioner and the air conditioner repeater are connected via a cable, transferring a wireless signal received from the remote controller in a Bluetooth method to the air conditioner.
