METHOD AND DEVICE FOR MANAGING REFRIGERATION QUALITY OF REFRIGERATED CARGO

A method and apparatus manage a refrigeration quality for a refrigerated cargo by detecting refrigeration condition abnormality of a refrigeration system of a vehicle. The method includes: receiving refrigeration quality reference data for the refrigerated cargo, obtaining a target temperature and an allowable time range data that are set based on the refrigeration quality reference data, determining whether an offset from the target temperature has occurred, comparing the allowable time range data with a duration for which the offset from the target temperature occurred, and determining, based on comparing the duration of the offset with the allowable time range data, whether the refrigeration system is in a suspected refrigeration condition abnormality state.
