RFID technology used in railway transportation logistics industry

The traditional cold chain logistics and warehousing logistics monitors are not fully transparent, and the shippers and third-party logistics service providers have low mutual trust. Ultra-low temperature food refrigerated transportation, warehousing logistics, delivery steps, using RFID temperature electronic tags and pallet system software to maintain the efficient operation of cold chain logistics to ensure the safety factor of food in all supply chain management.

Everyone knows that rail freight is suitable for long-distance and large-volume freight transportation, and it is very advantageous for long-distance freight above 1000km. The territory of our country is wide, and the production and sales of frozen foods are far apart, which shows a beneficial external standard for the development of the railway line cold chain logistics. However, at this stage, it seems that the transportation volume of cold chain transportation in China's railway lines is relatively small, accounting for less than 1% of the total demand for the development of cold chain transportation in society, and the advantages of railway lines in long-distance transportation have not been fully utilized.

The whole process of transportation is not completely transparent: in order to control costs during the whole process of transportation, the third-party transportation company will have the situation that the refrigeration unit is turned off during the whole process of transportation, and the refrigeration unit is turned on when it arrives at the station. Chain logistics. When the goods are delivered, although the surface of the goods is very cold, in fact the quality has already been reduced.

存储过程并非完全透明:due to cost considerations, warehousing and logistics companies will start to use the power supply period at night to reduce the temperature of the warehouse to a very low temperature. During the day, the refrigeration equipment is on standby, and the temperature of the frozen warehouse fluctuates beyond 10 Higher conditions immediately lead to a reduction in the shelf life of food. The traditional monitor method generally uses a temperature video recorder to accurately measure and record the temperature of all the cars or cold storage. This method must be connected to the cable TV and manually controlled to export the data, and the data information is in the hands of the carrier company and the warehouse logistics company. On the shipper, the consignor could not easily read the data. Because of concerns about the above difficulties, some large and medium-sized pharmaceutical companies or food companies in China at this stage would rather invest huge amounts of assets in the construction of frozen warehouses and transportation fleets, rather than choose the services of third-party cold chain logistics companies. Obviously, The cost of such capital investment is extremely great.

Invalid delivery: When the delivery company picks up the goods in manufacturing company A, if it is not possible to transport with pallets, the employee must transport the goods from the pallet to the refrigerated transport vehicle; after the goods arrive at the storage company B or to the retail company C, the employees must be After the goods are unloaded from the refrigerated transport truck, they are stacked on the pallet and then checked into the warehouse. This usually causes the re-delivery of the second goods, which not only takes time and labor, but also easily damages the packaging of the goods and harms the quality of the goods.

Treasury management has low efficiency: When entering and leaving the warehouse, you must present paper-based outbound and inbound receipts, and then enter the computer by manual production. The entry is efficient and slow, and the error rate is high.

Human resources management is extravagant and wasteful: the loading, unloading and handling of goods and code disks must be serviced by many people. When warehousing and logistics enterprise B rents a warehouse, it is also necessary to set up warehouse management staff.

RFID solution

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

Based on RFID technical pallet application. The scientific research that introduced this technology into the cold chain logistics industry has long been carried out. As a basic information management enterprise, pallets are conducive to maintaining accurate information management of large quantities of goods. Maintaining the information management of pallet electronic devices is a key way to carry out the supply chain logistics system software immediately, conveniently and quickly, with precise management methods and reasonable supervision and operation. It is of great practical significance for improving the freight logistics management capabilities and reducing transportation costs. Therefore, RFID temperature electronic tags can be placed on the tray. RFID electronic tags are placed on the tray, which can cooperate with the warehouse logistics intelligent management system to ensure instant inventory, accurate and accurate. Such electronic tags are equipped with wireless antennas, integrated IC and temperature controllers, and a thin, can The button battery, which has been continuously used for more than three years, has large digital signs and temperature information content, so it can very well consider the provisions of the cold chain logistics temperature monitor.

The core concept of importing pallets is the same. The pallets with temperature electronic tags will be presented or rented to the collaborative manufacturers for free, for the manufacturers to apply in the cold chain logistics center of the railway line, to keep the pallet work delivered consistently, and to speed up the pallets in the manufacturing enterprises, delivery enterprises, cold chain The application of intermediate circulation systems in logistics centers and retail enterprises to promote pallet freight and professional work 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 containers are immediately transported to the loading and unloading platform of the enterprise B's freezer warehouse, and the demolition inspection is carried out. The electric forklift removes the goods with pallets and places them on the conveyor. There is an inspection door developed at the front of the conveyor, and mobile reading software is installed on the door. After the RFID electronic tags on the cargo box and the pallet enter the coverage of the reading software, it contains the information content of the goods loaded by the enterprise A in the integrated ic and the information content of the pallet. The moment the pallet passes the inspection door, it is read by the software Obtained and transferred to computer software. If the worker takes a look at the display, he can grasp a series of data information such as the total number and type of the goods, and there is no need to manually check the actual operation. If the content of the cargo information displayed on the display screen matches the shipping list presented by Enterprise A, indicating that the standard is met, the employee presses the OK button next to the conveyor, and the goods and pallets will be stored in the warehouse according to the conveyor and automated technology stacker The storage space allocated by the logistics intelligent management system.

交付的卡车。在收到订单信息rmation from company C, company A notifies company B of the truck's delivery. According to the order information pushed by company A, company B allocates the express delivery sorting of the goods, upgrades the RFID information content of the pallet goods, the goods sorted by the express delivery are loaded into new pallets, and the new goods information content is associated with RFID electronic tags and put into storage Warehousing shelves, waiting for production dispatch delivery. The goods are sent to the enterprise C with pallets. The enterprise C loads and unloads the goods after the engineering acceptance. The pallets are brought by the enterprise B.

Customers pick themselves up. After the customer's car arrives at the enterprise B, the driver and the frozen storage technician check the content of the pickup information, and the automated technical storage equipment transports the goods from the frozen storage to the loading and unloading station. For transportation, the pallet is no longer shown.
