Solution Overview
Problem
Existing air conditioning maintenance systems do not effectively address maintenance tasks for causes other than corrosion of metal components, leading to potential failures and inefficiencies in scheduling and component supply.
Innovation Solution
A system comprising an abnormality detection device, maintenance management device, and maintenance assistance device that uses trained models to detect abnormality causes, prioritize maintenance tasks, and determine schedules based on statistical data, ensuring timely maintenance by identifying required components and optimizing logistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance tasks are scheduled based on corrosion of metal components only, then corrosion-related maintenance can be performed timely, but other abnormality causes are not addressed leading to potential failures
Solution Approach 1:
The system extends maintenance coverage from solely corrosion-related tasks to multiple abnormality causes including electrical component failures, mechanical issues, and operational anomalies. The maintenance management device schedules diverse maintenance tasks based on detected abnormality causes, enabling a single system to handle various maintenance scenarios effectively
Solution Approach 2:
The abnormality detection device performs continuous monitoring and detects potential abnormality causes before they lead to actual failures. By identifying issues early and scheduling preventive maintenance tasks, the system addresses multiple abnormality causes proactively rather than reactively, improving overall reliability
2Reliability
If maintenance tasks are performed frequently to cover all abnormality causes, then reliability improves, but time and resource consumption increases
Solution Approach 1:
The system schedules maintenance tasks selectively based on detected abnormality causes rather than performing all possible maintenance tasks frequently. The maintenance management device prioritizes tasks corresponding to detected issues, performing only the necessary partial set of maintenance actions required to address specific abnormality causes, thereby reducing unnecessary time consumption
Solution Approach 2:
The maintenance scheduling is dynamic and adapts based on real-time abnormality detection results. The system adjusts maintenance frequency and scope according to the specific abnormality causes detected, transitioning from static scheduled maintenance to dynamic condition-based maintenance, optimizing the balance between reliability and time efficiency
3Measurement precision
If comprehensive abnormality detection is implemented, then all maintenance needs are identified, but system complexity increases
Solution Approach 1:
The comprehensive abnormality detection system is segmented into specialized detection modules, each focused on specific types of abnormality causes such as electrical component failures, mechanical issues, or operational anomalies. This modular segmentation maintains high detection accuracy for each category while managing overall system complexity through organized, manageable components
Data Source
AI summary
A system includes: an abnormality detection device; a group of databases; a maintenance management device; and a maintenance assistance device. The abnormality detection device is configured to detect at least one abnormality cause from operation data of at least one air conditioning system by using a trained model. The group of databases includes a database in which identification information about each of the at least one abnormality cause or each of the at least one air conditioning system is associated with specific information about a maintenance task required to eliminate the abnormality cause. The maintenance management device is configured to manage a maintenance task for each of the at least one air conditioning system. The maintenance assistance device is configured to transmit, to the maintenance management device, maintenance information determined using specific information associated, in the group of databases, with an abnormality cause detected by the abnormality detection device.
