Air conditioning system and controlling method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning systems lack real-time monitoring capabilities, transferring data only hourly, and overload databases with frequent data retrieval, making it difficult to diagnose errors promptly and efficiently manage increasing monitoring sites.
Innovation Solution
An air conditioning system with a data collection gateway and server that collects and transfers state information from outdoor and indoor units in preset periods, allowing for real-time monitoring and reducing database load by outputting data at shorter intervals only when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transferred hourly in conventional air conditioning systems, then system complexity is reduced, but real-time monitoring capability is lost
Solution Approach 1:
The patent implements dynamic data transfer intervals where the gateway adapts the data collection frequency based on system state and user requirements. During normal operation, data is transferred at longer intervals to reduce load, while during abnormal conditions or when real-time monitoring is requested, the interval shortens automatically, providing both real-time capability and reduced complexity
Solution Approach 2:
The system employs periodic data transfer with variable periods. Instead of fixed hourly transfers, the gateway performs data collection and transfer at dynamically adjusted periodic intervals, allowing the system to switch between frequent real-time monitoring and less frequent routine reporting based on operational needs
2Measurement precision
If data transfer interval is shortened for real-time monitoring, then monitoring precision is improved, but system load increases
Solution Approach 1:
The gateway dynamically adjusts the data transfer interval based on real-time system conditions and user requests. When real-time monitoring is required, the interval shortens to improve precision; when not required, the interval extends to reduce system load, energy consumption, and database pressure
Solution Approach 2:
The system changes the time parameter (data transfer interval) dynamically based on monitoring requirements. This parameter adjustment allows the system to optimize between monitoring precision and resource consumption by varying the interval from short (real-time) to long (energy-saving) as needed
3Loss of information
If data is collected from all outdoor and indoor units frequently, then monitoring completeness is improved, but database load increases
Solution Approach 1:
The gateway implements selective data collection where it gathers complete information from all units when needed for comprehensive monitoring, but transfers only essential or changed data during routine operations. This partial action approach maintains monitoring completeness while reducing unnecessary database writes and load

AI summary
An air conditioning system and a controlling method of the same are disclosed. A controlling method of an air conditioning system includes an information collecting step configured to collect the state information or the operation information of the outdoor unit or the indoor unit in a preset period by using the gateway (130), an information transferring step configured to selectively transfer the information collected in the information collecting step to the data collecting server in a preset period, an information storing step configured to transfer the operation information or the state information of the outdoor unit or the indoor unit out of the information transferred in the information transferring step to the data storage server and to store the transferred information in a preset period; and an information outputting step configured to output the state information or the operation information of the outdoor unit or the indoor unit transferred in the information transferring step to the output unit at predetemined intervals shorter than the preset period by using the data collection server, when there is information transfer requirement.
