RFID cold chain logistics and transportation realizes intelligent management

Cold chain logistics is to carry out transportation operations in a low temperature environment. With the rapid development of various scientific and technological fields and the application of refrigeration technology, cold chain transportation has achieved unprecedented development trends. Due to the development of social economy and the continuous improvement of people's living standards, the types of cold chain goods are increasing, and the time control requirements for transportation are getting higher and higher. The emergence of RFID temperature tags seems to make all links simpler and more efficient. RFID temperature tags can collect and record the ambient temperature values of transported goods, record the ambient temperature of goods in each link of production, storage, transportation, sales, and consumption, and realize the temperature traceability data recording of the whole process. Due to its real-time, large-scale tag reading at the same time and good scalability, it is more suitable for cold chain vehicle temperature monitoring, thereby improving the quality management of goods. RFID cold chain logistics transportation realizes intelligent management.

At present, the cold chain Logistics industry is developing towards networking, standardization, scale, and groupization, and has huge development space. In response to market demand, some cold chain vehicle monitoring systems have appeared on the market, but these monitoring systems cannot monitor cold chain vehicles in all directions. When problems occur, they fail to remind in time to solve them, and fail to play a role in preventing them and reducing unnecessary losses.

RFID is used as an identification to identify products. For the modern cold chain transportation industry, it is not only concerned with the identification of its products, but also the temperature values associated with them. The temperature tag can meet the requirements of cold chain transportation temperature monitoring because it has both digital identification and temperature information.

RFID temperature tags provide energy for temperature collection and storage through built-in batteries, and can independently complete temperature collection and storage. When entering the effective identification range of the card reader, it obtains energy through the excitation of the card reader to complete data exchange. This temperature tag has extremely low current consumption.

RFID technology will realize functions.

Entry of cargo information in the tag. Cargo information is entered when the cargo is packaged or loaded. The cargo information includes the loading and unloading locations of the cargo, the variety, type, weight, and number of the cargo, and the cargo information entry operator code.

Tag installation. After the tag information is collected, the RFID tag is installed on the cargo, and the cargo is registered when it enters and leaves the carriage. The recorded information will be uploaded to the server for server-side dispatch and command.

The card reader reads the tag information. When the goods are loaded or unloaded, the tag information is read, Stored and displayed on the vehicle terminal to remind the driver of the destination for loading and unloading, and uploaded to the server at the same time.

When the product is out of the warehouse, the RFID temperature tag will be attached to the surface of the object to be tested according to the needs of cargo transportation, and the temperature range will be set. The temperature tag will automatically record the temperature, and the ambient temperature value will be recorded continuously with the preset collection cycle, and the handheld terminal will display it in real time, and an alarm will be issued if the temperature range is exceeded; during the cargo transfer process, the information and temperature of the cargo box RFID tag are read through the handheld terminal to ensure the validity of the goods; when the product is put into the warehouse, the handheld terminal can conveniently, quickly and accurately sort the goods according to the RFID tag information, and verify whether its temperature meets its storage temperature. When the goods that meet the storage temperature requirements are put into the warehouse, the temperature data will be synchronously imported into the database, and the temperature record of the whole logistics process is realized, ensuring the product quality.

Strict temperature control is the core of the quality assurance of cold chain goods. Cold chain goods can easily cause the goods in the transportation place to be stale or deteriorate due to carelessness or accidents in storage or transportation, which may not only affect the nutrition and taste changes, but also have adverse effects on the health of consumers and reduce the value. Therefore, RFID temperature electronic tags have become an important part of tracking and monitoring in cold chain logistics. It also allows information recording and timely handling of problems during transportation to ensure the quality of goods delivery.
