RFID technology is used in the railway transportation and logistics industry

The traditional cold chain logistics and warehousing logistics monitoring process is not fully transparent, and the mutual trust between shippers and third-party logistics service providers is low. The refrigerated transportation, warehousing, and delivery steps of ultra-low temperature food use RFID temperature tags and pallet sharing systems to maintain the efficient operation of cold chain logistics and ensure the safety of food in the entire supply chain.

As we all know, railway freight is suitable for the transportation of long-distance and large quantities of goods, especially long-distance freight of more than 1,000km. my country's vast territory and long distances between frozen food production and sales areas provide useful external conditions for the development of cold chain logistics via railway lines. However, at this stage, it seems that the cold chain transportation volume of railway lines in our country is small, accounting for less than 1% of the total demand for cold chain transportation in social development, and the advantages of railway lines in long-distance transportation have not been fully utilized.

There is a problem

After the products are manufactured and packaged by Company A, they are Stored in the manufacturer's freezer. Products are immediately stacked on the floor or on pallets. Manufacturing company A notifies the freight company to deliver the goods, which can be delivered to retail company C immediately. Or company A rents a part of the warehouse from warehousing and logistics company B, sends the goods to warehousing and logistics company B, and then distributes them through B when necessary.

The entire shipping process is not completely transparent

In order to control costs during the transportation process, third-party transportation companies may turn off the refrigeration unit during the transportation process and turn it on again when approaching the destination, which cannot guarantee full-line cold chain logistics. When the goods are delivered, although the surface of the goods is very cold, the quality has actually been reduced.

Stored procedures are not fully transparent

For cost reasons, warehousing and logistics companies may use the power supply at night to lower the temperature of the warehouse to a very low level and put the refrigeration equipment on standby during the day. This may cause the temperature of the refrigerated warehouse to fluctuate beyond 10°C or even higher. Immediately results in reduced shelf life of food. The traditional monitoring method usually uses a temperature recorder to accurately measure and record the temperature of the entire car or cold storage. This method requires a cable connection and manual control to export the data, and the data is in the hands of the shipping company and the warehousing and logistics company. , the shipper cannot easily read the data. Because of concerns about the above problems, some large pharmaceutical companies or food companies in China are currently willing to invest huge amounts of money to build cold storage and transportation teams rather than choose the services of third-party cold chain logistics companies. Obviously, The cost of such investment is extremely high.

invalid shipping

When the shipping company picks up the goods from manufacturing company A, if it cannot transport the goods with a pallet, the employees must transport the goods from the pallet to the refrigerated transport truck; after the goods arrive at storage company B or retail company C, employees must transport the goods from After unloading the refrigerated transport trucks, they are stacked on pallets and then checked into the warehouse. This results in re-transportation of goods, which is not only time-consuming and labor-intensive, but can also easily cause damage to the packaging of the goods and affect the quality of the goods.

Warehouse management efficiency is low

When entering or exiting the warehouse, paper receipts must be presented and entered into the computer manually. The entry efficiency is slow and the error rate is high.

Human resource management is extravagant and wasteful

The loading, unloading, handling and palletizing of goods require a lot of manual services. When warehousing and logistics company B rents a warehouse, it must also set up warehouse management staff.

RFID solutions

Create an intelligent railway line cold chain logistics center that can provide a full range of services such as cargo transportation, warehousing logistics, inspection, express sorting, and delivery.

Pallet application based on RFID technology. Research into introducing this technology into the cold chain Logistics industry has long been carried out. As a basic information management company, pallets are conducive to maintaining accurate information management of large quantities of goods. Maintaining informatized management of pallet electronics is an important method for direct, convenient, accurate management and effective supervision and control of the supply chain logistics system. It is of great significance for improving freight logistics capabilities and reducing transportation costs. Therefore, RFID temperature electronic tags can be placed on the pallet. Placing RFID tags on the pallet can cooperate with the warehousing and logistics intelligent management system to ensure real-time inventory and accuracy. This type of tag is equipped with an antenna, a chip and a temperature controller, as well as a thin, Button batteries that have been in use for more than three years can well meet the requirements of cold chain logistics temperature monitors because they also have digital signs and temperature information.

Introduce the core concept of pallet sharing. Pallets with temperature tags inserted will be provided or rented to cooperative manufacturers free of charge for manufacturers to use in railway cold chain logistics centers to ensure consistent delivery of pallets and speed up the use of pallets in manufacturing companies, transportation companies, and cold chains. The application of intermediate circulation systems in logistics centers and retail enterprises promotes pallet freight and professional work, which can improve the efficiency of freight logistics, reduce delivery time, and significantly reduce transportation costs.

After the train arrives at the arrival station, the refrigerated container is immediately transported to the cold storage loading and unloading platform of Company B, where it is unlabeled and inspected, and it is placed into the warehouse after meeting the standards. The electric forklift removes the cargo belt pallet and places it on the conveyor. There is an inspection door at the front end of the conveyor, and a mobile reading software is installed on the door. After the RFID tags on the cargo boxes and pallets enter the coverage of the reading software, they include the cargo information loaded into the chip by company A and the information on the pallet. The moment the pallet passes through the inspection door, it is read by the software. obtained and transferred to computer software. The staff can grasp a series of data such as the quantity and type of the goods by just looking at the monitor, eliminating the need for manual inspection at all. If the cargo information displayed on the screen matches the shipping document provided by Company A, indicating that the standard is met, the employee presses the OK button next to the conveyor, and the cargo and pallet will be stored in the warehouse through the conveyor and automated stacker. On the storage location allocated by the logistics intelligent management system.

Truck distribution. After receiving the order information from Company C, Company A notifies Company B of truck distribution. Based on the order information sent by Company A, Company B arranges express sorting of the goods, updates the RFID information of the pallet goods, loads the sorted goods into new pallets, and associates the new goods information with RFID tags and puts them into storage. Warehouse shelves, waiting for production dispatch and delivery. The goods are sent to Company C on pallets. Company C loads and unloads the goods after acceptance of the project, and the pallets are brought to Company B.

Customer pick up. After the customer's car arrives at Company B, the driver and the cold storage technician check the pickup information. The automated storage equipment tranSports the goods from the cold storage to the loading and unloading platform. The loading and unloading workers immediately unload the goods from the pallet and load them into the customer's vehicle. In terms of transportation, pallets are no longer provided at this time.
