Novel smart label and monitoring method applied to cold chain monitoring

Abstract

The invention discloses a novel smart label and a monitoring method which are applied to cold chain monitoring. The smart label includes a carrying main body, a recognition area, a color changing area and a contrasting area; wherein the recognition area is arranged on the carrying main body; the color changing area is arranged on the recognition area or the carrying main body; and the contrasting area is arranged near the color changing area, or is arranged on the carrying main body or the recognition area. With the novel smart label and the monitoring method applied to the cold chain monitoring adopted, real-time recognition and characterization of the quality statuses of commodities such as medicines and food can be realized, and the real-time acquisition of the comprehensive information of terminal commodities can be realized for manufacturers, supervisory departments and consumers.

Description

technical field [0001] The invention relates to an intelligent label with color change caused by irreversible temperature-time coupling in a low-temperature storage environment and a product monitoring method based on the label. Background technique [0002] With the rapid development of medicine and food refrigeration technology, consumers' demand for medicine and food quality continues to increase. The traditional production date, delivery date and shelf life of basic medicine and food information can no longer meet consumers' demands for medicine and food quality, etc. Cognitive appeal of the product. Consumers expect drug and food manufacturers to enable drug and food packaging to carry more information about the process of drugs and food in circulation, storage and transportation, and to obtain real-time information about the quality of drugs and food. Therefore, it is necessary to design and develop a low-cost intelligent label for medicines, food and other commoditie...

Problems solved by technology

[0003] Although there are currently color indicators or labels for food quality monitoring, they are easily affected by other environmental factors such as ambient temperature, humidity, pH, etc., and the judgment of these colors is based on subjective judgments of the human eye and is easily affected by light. The impact of the environment, thus greatly affecting the accuracy of label use

Even though radio frequency (RFID) and other electronic label products have been applied to the monitoring of commodity logistics and quality information, their cost is relatively high, and it is difficult to meet the application requirements for pharmaceuticals and fresh agricultural products.
