With people's pursuit of health preservation and healthy life, the demand for high-quality fresh fruits and vegetables is also increasing. As one of the most effective storage and preservation methods for fruits and vegetables recognized internationally, modified atmosphere preservation is a method to achieve freshness by improving the gas composition of the storage environment. However, at present, the functions of controlled atmosphere devices in my country are relatively single, and the cost of corresponding equipment is high, which is common in large quantities of single-variety fruits and vegetables stored for a long time. Traditional low-temperature and cold storage methods reduce the bacteria's spoilage effect on food by reducing the reproduction and metabolism of bacteria, but cannot completely eliminate the spoilage effect of bacteria.

Among them, it should be explained that if a consumer purchases fresh products online, the buyer can use the fresh-keeping device to transport the products purchased by the consumer, and the courier will go to the merchant to pick up the goods, or the merchant will send the goods to the courier company. The courier selects the size of the fresh-keeping device according to the quantity of goods, and stores the order number and box ID number of the goods purchased by the user into the remote server. The courier company arranges the transportation normally. When the fresh-keeping device arrives at the designated place, the courier will send The withdrawal code is given to the corresponding user so that the user can obtain the goods.

Step S102: The remote server determines whether the first identity information carried in the door opening request has door opening authority based on the stored identity information.

After receiving the door opening request sent by the user terminal, the remote server matches the first identity information carried in the door opening request based on the pre-stored identity information to see if it can be matched. If it can be matched, it indicates that the user If you have the authority to open the door, execute step S103. If not, send a control command without the right to open the door to the fresh-keeping device, so that the fresh-keeping device reminds the user that there is no right to open the door based on the control command without the right to open the door.

Step S103: the remote server responds to the door opening request, and sends information indicating that the door is approved to be opened to the fresh-keeping device.

If after the identity information verification is passed, that is, when there is door opening authority, the remote server responds to the door opening request and sends an instruction indicating that the door is opened to the fresh-keeping device to realize the opening of the door, and the user can take out the stored objects.

Among them, it should be noted that when the user picks up the goods, the fresh-keeping device scanned by the user may be the same as or different from the fresh-keeping device transported by the courier. In the fixed fresh-keeping devices, these fixed fresh-keeping devices are specially used for storing articles that need to be kept fresh, and the effect of the cargo cabinets in the prior art is the same. The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
