Description

A new smart label and monitoring method for cold chain monitoring

technical field

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

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 commodities, so that manufacturers, regulatory authorities and consumers can simultaneously obtain comprehensive information such as logistics and quality of medicines and food.

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 has greatly affected the accuracy of label use. Even though radio frequency (RFID) and other electronic tag 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 medicines and fresh agricultural products.

detailed description

As shown in Figure 1, the temperature-time coupling-induced chromic smart label under the refrigerated chain storage and transportation environment includes a carrier body 1, which can be a self-adhesive paper coated with glue on one side, and on the unglued surface of the carrier body 1 An identification area 2 is provided, and the identification area 2 includes identifiers such as barcodes, two-dimensional codes or identification serial numbers printed on the carrier body; a color-changing area 3 is also provided on the identification area 2 or on the carrier body 1, and the color-changing area 3 includes An irreversible temperature-time coupling color-changing material coated or printed on the color-changing area 3; a contrasting area 4 is provided near the color-changing area 3, for example, the color-changing area 3 is located in the center of the label-carrying body in Figure 1 and covers the identification area 2, the contrast area 4 is set around the discoloration area 3, the discoloration area 3 can be circular, and the contrast area 4 is ring-shaped, surrounding the discoloration area 3. The contrast area 4 is a standard color area that does not change color due to the influence of temperature-time coupling, and the color of the contrast area 4 is the original color of the discoloration area 3 .

Irreversible temperature-time coupling color-changing material is a material that gradually changes color over time, and its color-changing speed is also affected by the ambient temperature. The discoloration speed of the discoloration material is relatively slow, and when the temperature is above the safe temperature, as the temperature increases, the discoloration speed of the discoloration material will also be accelerated. The color-changing material is divided into two types, one is the color-changing material that can be recognized by the naked eye, that is, its color change can be directly recognized by the naked eye of a person, and this kind of color-changing material can be selected from the QM7D5 label produced by Suzhou Huashi Thermal Technology Co., Ltd. Material. The other is a color-changing material that is not recognized by the naked eye, and its color needs to be irradiated by an energy excitation device such as an ultraviolet lamp to develop color.

When the irreversible temperature-time coupling color-changing material on the product label changes color, the product quality can be determined according to the color change. If the label color is closer to the original color, it can be determined that the product has been at a safe temperature during the circulation process If the label color has a certain change and is different from the original color, it can be determined that the ambient temperature of the product has exceeded the safe temperature during the circulation process or the product has been circulated for a certain period of time. For example, after 3 months, the product quality is normal at this time; if the color of the label changes significantly, which is very different from the original color, it can be determined that the ambient temperature of the product has seriously exceeded the safe temperature during the circulation process or the product The shelf life has been exceeded, and the product quality is unqualified at this time.

Product monitoring methods based on this smart label include:

Step S1, printing or coating an irreversible temperature-time coupling chromogenic material on the identification area of the smart label including the color-changing area or on the carrier body of the smart label;

Step S2, attach the smart label to the product, and officially enter the circulation link with the product;

Step S3, collect the image information of the smart label through the client (which can be photographed by the camera module) and perform the following identification:

(1) Color recognition: identify the color of the discoloration area, and obtain the color information of the discoloration area;

(2) Code recognition: identify barcode or two-dimensional code, and obtain barcode information or two-dimensional code information;

Send the obtained color information of the discoloration area and barcode information or two-dimensional code information to the server.

Before performing color recognition and code recognition, it preferably also includes the step of performing image preprocessing on the collected images.

Step 4. After receiving the color information of the discoloration area and the barcode information or QR code information, the server compares the color information of the discoloration area with the color information stored in the database to obtain the quality information of the product, including good, normal and bad. Qualified; at the same time, the server searches the database according to the barcode information or two-dimensional code information, and obtains the corresponding original product information, such as product name, production date, manufacturer, etc.; the server sends product quality information and product original information to client;

Further, before the server performs color comparison, step 4 also includes a correction step: the server corrects the received color information of the discoloration area.

Step 5: The client displays the original product information and product quality information.

In addition, when the color-changing material in the color-changing area is selected from a color-changing material that is not recognized by the naked eye, the following steps are also included before step 3 and after step 2:

Step 2a, irradiating the smart label through an energy excitation device, so that the color-changing area develops color;

The beneficial effect of the present invention is that: the temperature-time coupled chromic smart label and the product monitoring method based on the smart label are a low-cost, easy-to-storage, easy-to-identify scheme, which realizes the basic The real-time representation of logistics information and quality information facilitates the real-time acquisition of comprehensive information on the quality of drugs, food, etc. by departments at each node of the supply chain, manufacturers, regulatory authorities, and consumers, and realizes the real-time carrying and information visualization of information on drugs, food, etc. .
