Controller and air conditioning management system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air conditioning control systems face challenges in equalizing the operability of local and remote controllers due to differences in screen customization, leading to increased delay times and deteriorated remote controller operability, especially when data is relayed through an intermediate server.
Innovation Solution
A controller system that connects to air conditioners and networks via firewalls, using a server to synchronize display screen customizing information between local and remote controllers, ensuring identical display screens across both types of controllers by exchanging setting information and renewal information through communication interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If screen customizing information is manually updated on each controller, then display consistency can be achieved, but the time and labor required increases significantly
Solution Approach 1:
The patent implements automatic copying of screen customizing information from a master controller to remote controllers through a server. When screen layout information is updated on one controller, it is automatically copied and synchronized to all other controllers, eliminating manual reconfiguration and ensuring display consistency across the network.
2Reliability
If a server is used to relay data between controllers, then network security is improved, but the delay time for screen renewal increases
Solution Approach 1:
The patent implements preliminary action by having controllers send screen customizing information to the server in advance. The server stores this information and proactively pushes updates to remote controllers when changes occur, rather than waiting for requests. This reduces the perceived delay while maintaining secure server-mediated communication.
3Ease of operation
If screen customizing information is exchanged between controllers, then operability equalization is achieved, but the complexity of the communication system increases
Solution Approach 1:
The patent introduces a server as an intermediary to manage screen customizing information exchange between controllers. The server acts as a central repository and distribution point, simplifying the communication architecture by eliminating direct peer-to-peer connections and providing a single point of control for information synchronization.
4Adaptability or versatility
If multiple remote controllers are deployed, then remote access capability is improved, but the effort to synchronize display settings across all controllers increases
Solution Approach 1:
The patent implements universality by creating a centralized server system that serves all remote controllers with a unified screen customizing information management mechanism. The server provides universal functionality for storing, managing, and distributing display settings to any number of controllers, making the system scalable without increasing per-controller complexity.

AI summary
When first screen customizing information is changed in order to change a first display screen, a local controller sends first setting information indicating a changed part of the first screen customizing information to a server. When second screen customizing information is changed in order to change a second display screen, a remote controller sends second setting information indicating a changed part of the second screen customizing information to the server. The server sends first renewal information identical to the second setting information to the local controller and sends second renewal information identical to the first setting information to the remote controller; the local controller changes the first display screen in accordance with the first renewal information; and the remote controller changes the second display screen in accordance with the second renewal information.
