Air-Conditioner Remote Monitoring for Missing Data Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote monitoring systems for air-conditioners face issues with data loss during network failures and present operation data in a complex, difficult-to-understand format, especially due to low terminal performance and reliance on cloud resources.
Innovation Solution
A remote monitoring system that includes a storage device on the air-conditioner to record operating state data, a communication control unit to transmit data with missing portions upon network recovery, and a server to generate and present refrigerant circuit diagrams for user understanding, ensuring data integrity and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operation data is transmitted only when no missing portion exists, then network communication efficiency is improved, but data completeness may be compromised during network failures
Solution Approach 1:
The system performs preliminary actions by storing operation data locally in the storage device before network transmission is needed. The air-conditioner continuously records operation data in its storage device during periods when network communication is available, preparing the data in advance so that it can be transmitted reliably when the network is restored, preventing data loss during network failures.
Solution Approach 2:
The communication control unit implements a feedback mechanism by checking whether the server has successfully received operation data before determining what to transmit next. It receives acknowledgment information from the server indicating whether data reception was successful, and based on this feedback, it intelligently decides whether to transmit newly recorded data, previously stored data, or both, thereby ensuring data completeness while maintaining communication efficiency.
2Loss of information
If all operation data is transmitted to the server, then data completeness is improved, but network bandwidth consumption increases
Solution Approach 1:
The system applies partial action by transmitting only the necessary portion of operation data to the server. The communication control unit determines whether to transmit newly recorded data, previously stored data, or both, based on whether the server has successfully received previous data. This selective transmission approach ensures data completeness is maintained while avoiding unnecessary network bandwidth consumption by not retransmitting data that has already been successfully received.
3Measurement precision
If numerical operation data is presented directly to users, then data accuracy is maintained, but user understanding becomes difficult
Solution Approach 1:
The system changes the parameter of data presentation from raw numerical values to visual graphical representations. The server generates graphical information that visually represents the operation data, transforming accurate but difficult-to-understand numerical parameters into easily interpretable visual forms such as charts or diagrams, thereby maintaining data accuracy while significantly improving user understanding.

AI summary
A remote monitoring system includes a remote monitoring apparatus and a network server. The network server is configured to request, a) when there is no missing portion in an operating state obtained from the remote monitoring apparatus until now, the remote monitoring apparatus to transmit an operating state newly recorded after previous obtainment of the operating state. The network server is configured to request, b) when there is a missing portion in the operating state obtained from the remote monitoring apparatus until now, the remote monitoring apparatus to transmit the operating state newly recorded after previous obtainment of the operating state and the missing portion that remains in a storage device.
