With the continuous improvement of people’s living standards and health awareness, higher standards are required for the home environment, and home intelligence has also become a major demand in the market. It has been pursuing intelligent refrigerators. In recent years, various technologies such as refrigerator intelligentization, voice, automatic adjustment, etc. have emerged in an endless stream, and food management and preservation have become a highlight. When cooking, I often find that there is no food in the refrigerator and worry about it; sometimes the long-term consumption of the food in the refrigerator expires. The smart refrigerator adds an RFID electronic tag to the food to automatically identify the type and time of the stored food, so that the information of the food in the refrigerator can be quickly known.
According to relevant information, Hisense officially released the world’s first global RFID food management refrigerator, which is the first in the industry to realize the use of RFID technology to identify and manage food materials in the refrigerator, freezer, and greenhouse, leading the refrigerator industry from food storage The era has entered the era of food management. RFID refrigerator intelligentizes a better life.
Only when the ingredients stored in the refrigerator are recognized can the management of the smart refrigerator be discussed. As a key technology for building the Internet of Things, RFID (Radio Frequency Identification Technology) electronic tags have been widely used in many industries. For example, international retail giants such as Wal-Mart and Metro have used RFID supply chain management technology. Clothing brands such as Decathlon and Uniqlo have introduced RFID technology in global stores for clothing management, control and scheduling.
Overview of RFID smart refrigerator management system
1. Paste the RFID label on the food packaging, install the RFID reading head inside the refrigerator, and install the display screen on the surface of the refrigerator.
2. When the food is put in the refrigerator, the system automatically reads and records the food information, and can display text information and pictures on the display.
3. The user can set the necessary food. When a certain food in the refrigerator is about to run out, the refrigerator will give a reminder, or remind the user through a mobile phone text message. Button to buy commonly used food.
4. Analyze the existing food in the refrigerator, recommend recipes to the user through the built-in program, and display it on the display.
5. Combine the smart refrigerator system with the RFID food traceability system to analyze the source and place of production of the food and other information. When the food is about to expire, the refrigerator sends out a reminder or sends a text message to the user’s mobile phone.
RFID technology for management improvement points
1. Real-time recording and query of food information in the refrigerator, combined with the RFID food traceability system, can query and analyze the food life cycle information, and improve user experience.
2. A reminder is issued when the food is about to expire to ensure food safety and reduce waste.
3. Combining food information, one-click shopping, greatly improving efficiency and saving manpower.
4. Combine the recommended recipes of the food in the refrigerator to assist decision-making.
However, due to the high technical threshold, few companies have successfully used RFID in the field of household refrigerators. In addition, RFID signals are easily blocked by food materials with high water content such as melons and fruits, and no company can apply RFID technology. Go to the cold storage area of the refrigerator. After difficult technical research, Hisense RFID has not only simply achieved food identification, but also achieved the identification and management of food materials in the entire field of refrigerators, freezers, and greenhouses for the first time in the industry.
The refrigerator’s intelligent function can monitor the quantity of ingredients, remind users to replenish or clean up in time according to the frequency of use of ingredients, and can realize intelligent recipes to recommend nutritious meals. In this way, the refrigerator has very little food waste, and it has become an expert in food management. This is a scientific design, which allows us to always clearly understand which items in the full refrigerator have been used up or are about to be used up, or which foods It is about to expire, which allows us to control living expenses more reasonably.
RFID technology has been used in more and more industries, and more convenient management of automatic collection and reading of information has been realized through RFID technology. Image recognition technology is common in the smart refrigerator industry, but RFID is more accurate in identifying food ingredients, and has a small impact on the storage space, so that food management is more flexible and convenient.
