In the existing technology, for articles such as tangerine peel that have certain preservation condition requirements, there is a lack of an efficient preservation system that integrates multiple functions. On the one hand, articles are prone to getting damp and deteriorating due to high environmental humidity during preservation, which affects their quality and value. However, the current moisture-proof measures on the market often have limited effects and cannot monitor and regulate the humidity environment in real time. On the other hand, in the preservation and transportation links of articles, it is impossible to accurately locate and track them, which is likely to cause the loss of articles or make it difficult to trace their location information, bringing potential safety hazards to the safety management of articles. In addition, for some preservation scenarios with high requirements for sanitary conditions, the existing equipment usually does not have an effective sterilization function and is difficult to ensure the cleanliness of the preservation environment.
