Solution Overview
Problem
Multi-connected systems in air conditioning, which use power line carrier communication, face challenges such as complex wiring and high costs due to the need for dedicated communication lines, and struggle to meet user needs, particularly in environments with multiple doorways where line controllers must be installed for each room.
Innovation Solution
A data sending method and multi-connected system that utilize a central coordinator to store pairing relationships between line controllers and indoor units, allowing data to be sent to determined devices via existing power lines, enabling multiple line controllers to control a single indoor unit without the need for re-wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated communication lines are used for each line controller, then communication reliability is improved, but device complexity and installation cost increase
Solution Approach 1:
The patent merges multiple communication channels into a single power line infrastructure. Instead of dedicating separate communication lines to each line controller, the system combines data transmission for multiple line controllers through the existing power line network, reducing wiring complexity while maintaining communication reliability through logical addressing and data routing protocols.
Solution Approach 2:
The power line is given multiple functions: it serves both as the power supply line and as the communication medium for multiple line controllers. This universal use of the power line infrastructure eliminates the need for dedicated communication lines, reducing installation complexity and cost while supporting multiple devices through the same physical medium.
2Adaptability or versatility
If a line controller is installed at each doorway, then control functionality is improved, but device complexity and installation cost increase
Solution Approach 1:
The system allows a single line controller to serve multiple doorways and indoor units through the shared power line communication infrastructure. Instead of requiring one physical line controller per doorway, the universal power line network enables one controller to manage multiple locations, reducing installation complexity while maintaining full control functionality at each doorway.
Solution Approach 2:
The patent introduces a door controller as an intermediary device that can be remotely controlled through the power line communication system. This door controller acts as a mediator between the line controller and the indoor units at different doorways, enabling distributed control functionality without requiring physical line controllers at every location.
3Ease of manufacture
If power line carrier communication is used, then ease of installation is improved, but data routing complexity increases
Solution Approach 1:
The system performs preliminary pairing and binding operations during installation to establish predetermined relationships between line controllers, door controllers, and indoor units. This preliminary configuration stores routing information in advance, simplifying subsequent data transmission and reducing the complexity of real-time routing decisions during system operation.
Solution Approach 2:
The patent implements feedback mechanisms where the central coordinator and controllers exchange status information, device identifiers, and routing data through the power line communication. This feedback enables dynamic route determination and ensures that data is correctly routed to the appropriate devices, managing routing complexity through intelligent control algorithms.
