Air Conditioning System Address Management Using Domain Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems face processing load issues due to complex processes for sharing and managing IP address information, leading to increased communication congestion and inefficiencies.
Innovation Solution
The system employs a dual communication method where outdoor units generate secondary addresses using primary addresses for both indoor and outdoor units, allowing the central control device to manage operations efficiently without direct communication between indoor and outdoor units, thereby reducing processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If IP addresses are assigned to all devices using DHCP and a central management device creates and shares an address table, then high-speed communication is enabled, but processing loads increase due to complex table management and sharing processes
Solution Approach 1:
The system divides the air conditioning system into multiple independent communication domains, each managed by a domain management device. Each domain has its own address table and management scope, preventing the need for a single centralized device to manage all addresses across the entire system. This segmentation reduces the processing load on individual devices while maintaining high-speed communication within each domain.
Solution Approach 2:
Domain management devices act as intermediaries between the central control device and individual air conditioning devices. These intermediaries locally manage address allocation and table maintenance within their respective domains, reducing the direct communication overhead and processing complexity that would otherwise fall on a centralized management device.
2Adaptability or versatility
If a centralized management device shares address tables among all devices, then IP communication can be performed throughout the system, but processing loads increase due to table sharing and change management
Solution Approach 1:
The address management system is segmented into multiple domain-specific management devices, each responsible for a specific domain. This allows the system to maintain adaptability across different domains while distributing the processing workload, as each domain management device independently handles address table maintenance for its own domain without burdening other domains.
Solution Approach 2:
Domain management devices pre-establish and maintain address tables for their respective domains before communication needs arise. This preliminary action allows address information to be readily available when needed, improving processing efficiency by avoiding real-time table creation and sharing operations during active communication.

AI summary
An air conditioning system includes: outdoor units; indoor units each communicating with any one of the outdoor units by a first communication method; and a central control device communicating with each of the outdoor units by a second communication method and controlling the outdoor units and the indoor units. One of the outdoor units generates, by using a first address used for communication performed using the first communication method, a second address used for communication performed using a second communication method, generates a second address for one or more of the indoor units by using a first address, and obtains second addresses from another outdoor unit and the central control device. The central control device obtains, from each of the outdoor units, second addresses of the outdoor unit and each indoor unit, and controls operations of the outdoor units and the indoor units by using the second addresses obtained.
