In the present application, the sample retention refrigerator has a plurality of independent chambers, which can independently retain the retained samples for each meal, and avoid the management loopholes caused by only one sample retention chamber in the prior art. And compared with the magnetic lock in the prior art, the electronic lock can only be opened when the control terminal is powered on, which avoids the lock failure of the magnetic lock caused by the power failure in the prior art, and thus avoids the potential risks caused by it. For example, the unscrupulous person makes the magnetic lock fail to lock by powering off, and then replaces the saved sample, resulting in the risk of "traceability" failure.

In a specific application scenario, as shown in FIG. 1 , the sample retention refrigerator 1 has twelve independent chambers. For example, six chambers are symmetrically arranged on both sides of the interior of the sample retention refrigerator, and the six chambers on each side are arranged vertically in sequence from top to bottom. These twelve independent chambers, each chamber is used to store the reserved samples corresponding to different meals,

Specifically, based on the four meals of breakfast, lunch, dinner and supper each day, twelve chambers are set up, and each chamber is used to store the reserved samples corresponding to different meals, that is, in use, the first chamber is used for storing The breakfast sample on the first day, the lunch sample on the first day in the second chamber... The twelfth chamber saves the night snack on the third day. In the relevant system of sample retention, it is required that the retained sample for each meal should be retained for 48 hours. When the retained sample for the fourth day's breakfast is to be retained, the retained sample for the first day's breakfast can be eliminated, and the first chamber can be reused. And so on….

In other words, setting up twelve independent chambers can realize a closed loop in the execution of sample retention, which is beneficial to the user's implementation of the food sample retention management system.

In a specific application scenario, as shown in Figure 1, the food sample retention system further includes a capture platform 6; the face recognizer 2, the capture device 3 and the capture platform 6 are arranged on the front side of the sample retention refrigerator, for example, the three are set In the middle of the front side, and on both sides are the chamber doors of each chamber; among them, as shown in Figure 1, the lens of the capture device is opposite to the upper end surface of the capture platform, so as to facilitate the retention of samples placed on the capture platform food to be photographed. For example, the captured pictures of the reserved food can be displayed better.

Similar to the prior art, when the present application is applied, the face recognizer 2 needs to be pre-configured with the face image of the staff responsible for keeping food samples. It should be pointed out that the face recognizer can identify the face image after configuring Sending a trigger signal is a general working principle in the related technologies of the face recognizer. This application only uses the working principle to describe the process of the embodiment, and does not involve making improvements based on the working principle.

The use process of the food sample retention system in this application is as follows:
