[0002] Commercial refrigerators are a type of food freezing / refrigeration equipment with a large storage capacity in the catering industry. In order to ensure efficient use of space, the storage area is generally not divided into zones, and catering practitioners generally use baskets for packaging. This application scenario has caused many problems, affecting the normal operation of catering stores and even causing food safety issues. Existing commercial air-cooled refrigerators (publication number: CN212481788U) have at least the following disadvantages:

[0003] 1. Food cannot be found in existing commercial refrigerators: Commercial refrigerators generally store items in a stacked manner, and users cannot accurately know the storage location and status of the target products. Therefore, a device that can know the storage location and status of the target products is urgently needed.

[0004] 2. Existing commercial refrigerators, food forgotten: multiple stored items cannot be retrieved according to the first-in-first-out usage logic, and it is difficult to ensure that the food you find is the one with the shortest remaining shelf life among similar foods in the refrigerator. As a result, food is easily overlooked in the lower layer or corner area of ​​the refrigerator and expires. Therefore, there is an urgent need for a device that can retrieve items according to the first-in-first-out usage logic.

[0005] 3. Existing commercial refrigerators, food is taken incorrectly: Many foods in catering stores have basically the same outer packaging and shape, which can easily lead to wrong taking, so there is an urgent need for a device that will not cause wrong taking.

[0006] 4. Existing commercial refrigerators, expired food: For scattered packaged products, it is impossible to identify whether the product is expired, or it is impossible to obtain information reminders of expiring food, so there is an urgent need for a device to obtain information reminders of expiring food.
