Container Refrigeration Impact Detection for Refrigerant Leak Diagnosis

The impact sensor performs preliminary detection of strong impacts before abnormalities can occur or develop. When impact exceeding a threshold is detected, the system proactively triggers abnormality diagnosis routines, rather than waiting for periodic self-diagnosis or for symptoms to manifest. This preliminary action enables timely detection of impact events that may cause refrigerant leakage or component damage.

The system implements feedback by continuously monitoring impact sensor data and using this information to control subsequent diagnostic actions. When the impact sensor detects strong impact, feedback signals trigger the control unit to immediately perform abnormality diagnosis, creating a closed-loop system where detection results directly influence further diagnostic behavior. This feedback mechanism ensures prompt response to impact events.

The control unit performs self-service by automatically initiating abnormality diagnosis routines when impact is detected, without requiring external intervention or complex additional hardware. The existing control unit leverages its own processing capabilities to monitor impact sensor data and trigger appropriate diagnostic sequences, allowing the system to serve its own diagnostic needs using already-present intelligence and control logic.

The control unit serves multiple functions: it controls the refrigeration cycle, monitors impact sensor data, initiates abnormality diagnosis, and coordinates sensor operations. By making the control unit multi-functional, the patent avoids adding separate dedicated control systems for impact monitoring, thereby reducing overall device complexity while achieving comprehensive diagnostic capability.

Instead of continuous monitoring that would consume constant energy, the system uses periodic action triggered by impact events. The abnormality diagnosis, including refrigerant leakage detection, is performed periodically only when strong impact is detected by the impact sensor. This event-driven periodic operation significantly reduces energy consumption compared to continuous monitoring, while still ensuring safety when needed.

The system takes preliminary anti-action by detecting impact and proactively preventing potential safety hazards before they can develop. When impact is detected, the system immediately initiates refrigerant leakage detection to prevent undetected leakage from creating safety risks. This preliminary safety check counteracts the potential harmful effects of impact-induced leakage before they can manifest as serious safety issues.
