Cold-chain logistics management device with shelf life prediction function, method thereof and application thereof

Abstract

The invention discloses a cold-chain logistics management device with the shelf life prediction function, a method of the cold-chain logistics management device and application of the cold-chain logistics management device. The cold-chain logistics management device comprises a temperature sensor, a humidity sensor, a carbon dioxide sensor, an ethylene sensor, a microprocessor unit, a display unit, an RFID storage unit and an RFID read-write unit. A user sends information such as the start record, the temperature collection interval, the product type and the initial shelf life to a cold-chain logistics management RFID card through any handset with an RFID data format before a product is placed on a shelf, and then the cold-chain logistics management RFID card is attached to the target product. After the cold-chain logistics management device is started, the display unit displays the initial shelf life, and the sensors transmit collected data to the microprocessor unit, calculate the remaining shelf life according to a shelf life prediction model by combining the specific product type, and display the remaining shelf life on the display unit. The cold-chain logistics management device with the shelf life prediction function, the method of the cold-chain logistics management device and application of the cold-chain logistics management device can achieve direct prediction of the real-time remaining shelf life of food or agricultural products.

Description

technical field [0001] The invention relates to agricultural product quality maintenance and quality safety control technology, in particular to an RFID device and method application for cold chain logistics management with a shelf life prediction function. Background technique [0002] With the continuous improvement of economic development level and residents' income level, consumers' food safety awareness is also increasing. More and more consumers pay attention to information such as production date and shelf life when purchasing food or agricultural products. In fact, the shelf life is not a scientific term. Not all links in the whole process of food from processing to logistics to consumers are the same. Food itself will undergo a series of dynamic changes. The shelf life on food packaging is only a fixed number of days under specific storage conditions, so the traditional shelf life cannot fully represent the actual food quality assurance, and fresh food such as agri...

Problems solved by technology

[0004] At present, electronic tags based on RFID technology have begun to be applied in a small amount in foreign markets, but the amount of information contained in the tags is very limited, usually only basic product information and temperature data, and the fusion technology of multi-parameter detection and electronic tags has not yet been developed.

At present, domestic research on the shelf life of food is mostly in the stage of theoretical and experimental research, and the traditional shelf life is still used in actual production and sales, especially for fresh food and agricultural products. The number of applications and the market are huge, but there is a lack of corresponding equipment.
