Applications of RFID in cold chain logistics management

In cold chain logistics, from the completion of goods collection to loading, there is still a business process of reviewing turnover boxes. The main function of the turnover box review is to check whether the number of turnover boxes on the storage space of the Store is correct, whether there is a "turnover box that belongs to the store is not on the collection space of the store, and a turnover box that does not belong to the store is in the store." The phenomenon of "on the collection space". This process requires reviewers to scan all the turnover boxes once. If there are a large number of turnover boxes in each store, the time required is considerable, which may lead to failure to load and ship goods in time after the collection is completed. As we all know, when identifying barcodes, the scanner must be aligned with the barcodes, and only one set of barcodes can be read at a time, which is why the review efficiency of turnover boxes is low.

Those applications of RFID cold chain Logistics Management

1. Refrigerated logistics production line link

Fresh food or pharmaceutical companies install temperature and humidity monitoring systems in production workshops to monitor environmental conditions during food processing and packaging. After the packaging process is over, paste an RFID temperature label on each package, and enter relevant information into the RFID electronic label, including processing technology, date, use of additives, food weight, grade, shelf life and other information, in order to prevent food safety accidents trace back. At the same time, the enterprise can plan the quantity and batches provided to the retailer through the information transmitted by the label, which is convenient for arranging shipment and dispatching staff, and improving work efficiency.

2. Refrigerated logistics storage link

In the cold chain logistics warehouse equipped with RFID Readers, when the goods with RFID tags enter the sensing area, the UHF reader can identify multiple tags at the same time at a long distance, and pass the information in the identified tags through The network uploads to the warehouse management system. The warehousing management system checks the quantity, type and other information of the goods with the warehousing plan to see if there is any error. At the same time, the system will also analyze the temperature information recorded in the label to judge whether the logistics process of the goods is safe. Information such as the receipt time and quantity of qualified goods is automatically entered into the system database. The warehousing system arranges the shelf position according to the warehouse information, calculates the moving distance of the goods into the warehouse, and tracks the goods to ensure that the goods are placed in the correct position. After the goods are put on the shelf, the temperature tag periodically records the measured temperature according to the predetermined setting, and transmits the temperature data to the RFID reader in the warehouse, and uniformly summarizes and transmits it to the system database for centralized management and analysis. When leaving the warehouse, the RFID reader is also used to read the RFID tags on the product packaging, and the storage system is compared with the export plan to record the time and quantity of the goods leaving the warehouse.

When entering and leaving the warehouse, the goods unloaded from the refrigerated truck are placed on pallets and transported by forklifts to the designated refrigerated warehouse. An RFID reader antenna is installed at the door of the cold storage. When a forklift passes by the door of the warehouse, the antenna will scan the RFID electronic tag on the forklift without manual intervention, and transmit the scanned information to the background, thereby Complete inventory of goods. Managers only need to use the computer to know the detailed information of the goods, such as quantity and variety. At the same time, through the temperature information sent back by the UHF reader, the administrator can know in detail whether there is any temperature exceeding the standard during the entire transportation process of the goods, so that the quality of the product can be judged in time to prevent quality problems happened.

3. The transportation link of cold chain logistics

During the cold chain transportation, the temperature label equipped on the cargo package detects and records the actual temperature at a certain time interval, and the RFID reader device installed on the vehicle is used to read the label data. Usually, the tag information and location information are automatically uploaded to the system information platform with the help of GPS technology. During the transportation process, if the temperature is abnormal, the system will automatically alarm to remind the transportation personnel to take remedial measures quickly to avoid the risk of chain breaking caused by human negligence.

Retailers can use the RFID cold chain system to obtain accurate delivery information and prepare for receipt. After the goods arrive, use the RFID handheld device to read the label information, compare and calculate with the purchase plan, analyze the temperature change information of the goods at the same time, judge the quality of the goods, and then decide whether to accept the goods, making the inspection work more efficient. Install supporting facilities in retail stores or Hospitals to monitor the temperature of items in real time to prevent losses caused by abnormal temperatures. RFID tags can also monitor the expiration date of time-sensitive products. Once the expiration date is exceeded, the tag will send an alarm to avoid complaints.

The cold chain logistics management system based on RFID technology can achieve the purpose of safety and traceability management of cold chain transport goods. Compared with manual determination of transportation methods, it is more efficient, real-time, and convenient, and can provide completely transparent management in cold chain logistics. , to ensure the visual control, monitoring and traceability of the goods throughout the process. After the temperature sensor is integrated with the electronic label, the enterprise can monitor the temperature throughout the process, promote the coherence of the cold chain logistics process, prevent chain breaks, ensure the traceability of food quality, and improve food safety. The joint application of RFID technology and logistics technologies such as GPS, GIS, EDI, and WMS can comprehensively improve the management level of food cold chain logistics and bring about fundamental changes in the cold and fresh food industry.
