When the distance between the refrigeration system and the target user is detected to be smaller than the preset distance value, the fact that the user approaches the refrigeration system and reaches a certain distance is indicated, and the target user may have an intention of opening the refrigeration system. In this embodiment, after it is detected that the target user may have an intention to open the refrigeration system, the initial state of the refrigeration unit in the refrigeration system is further detected.
The preset distance value may be set according to actual conditions, for example, the preset distance value may be set to 1 meter or 2 meters, and this embodiment is not limited.
