RFID intelligent logistics warehousing management method

logistics is a very important link in the commodity circulation supply chain and occupies an important position in the national economy, and warehousing is the core link of modern logistics. A large amount of warehousing information will be generated during the warehouse management activities. This information is often generated along with warehouse ordering, goods warehousing, goods management and goods outgoing.

Generally, it has the characteristics of frequent data operations, large data volume and complex information content. Efficient and reasonable warehousing can effectively control and manage goods. How to reduce inventory investment, strengthen inventory control and supervision, improve the utilization rate of space, personnel and equipment, and shorten the warehousing and outgoing processes and inspection time are the keys for enterprises to reduce costs and improve their competitiveness.

The development of warehousing has gone through three development stages: manual and mechanized warehousing, automated warehousing and intelligent warehousing. Information technology has become an important pillar of warehousing technology. The combination of automated warehousing and information collection and decision-making systems as well as the application of wireless radio frequency technology have made warehousing develop in an intelligent direction. The proposal of IoT (Internet of things) points out the direction for the development of intelligent warehousing systems. It connects goods with the Internet so that all items can be remotely sensed and controlled.

Logistics and warehousing management methods

1. Applying hardware equipment to the logistics process. The Internet of Things is a manifestation of the application of the Internet to the logistics and warehousing industry. This means that the Internet of Things can only be used where there is a network and related facilities. And in order for the Internet of Things to work smoothly in the warehouse, it is necessary to classify the storage time, delivery location and other information of all inventory goods in detail, and to paste barcodes and QR codes to facilitate information inspection of the products. Reduce the complexity and difficulty of subsequent work.

At the same time, information readers should be placed at the entrance and exit of the warehouse and connected to the computer to grasp and record information in a timely manner, ensure the circulation of information, facilitate the control of various products, and improve work efficiency.

2. Logistics Management technology for the Internet of Things must ensure that logistics warehouse work is carried out in an orderly and efficient manner, which requires cooperation and communication between various departments in all aspects. When products are shipped in and out of the warehouse, not only product information must be read, but also manual spot checks and confirmations of products must be performed to improve the accuracy of the work. During the inspection process, it is necessary to ensure that the product's network and document information are consistent with the actual situation, and to check whether the product is damaged or incomplete. Once a problem is discovered, contact the merchant in a timely manner to communicate and solve the problem together to ensure the quality of the goods in storage.

The staff responsible for overall control should input the relevant information into the computer, ensure the timely updating of the database, clarify the entry and exit time of the goods and the nature of the products, and classify and place the information according to the similarities and differences during the handling process, so as to facilitate Efficient implementation of follow-up work. When counting the products in the warehouse, the data information in the warehouse is downloaded in advance to ensure the integrity of the information of each product, and the staff uses a mobile terminal to scan the product barcode and check the information again. If any problem occurs, report it to the warehouse in a timely manner Administrator, and conduct secondary checks to fill loopholes and ensure product security and information accuracy.

When products leave the warehouse for distribution, managers must use professional mobile terminals to further verify and inspect the goods involved. And when shipping out of the warehouse, the handheld mobile terminal is used to count the brands and quantities of the goods shipped out of the warehouse, generate the shipping information, and compare the shipping information with the table of the goods shipped out of the warehouse to check whether there are any omissions. In addition, generating product information on the Internet of Things can facilitate manufacturers and buyers to query. By scanning the QR code to enter the website and query the product, the safety of the product can be ensured.

Intelligent logistics warehousing system processing steps

The intelligent logistics warehousing system must not only be able to carry out warehousing management, outbound management, movement within the warehouse, inventory management, allocation management, return and exchange management and report analysis, but also be able to monitor the position deviation of the goods and the temperature and humidity of the surrounding environment. Conduct video surveillance and fire alarm for warehouses.

Intelligent logistics and warehousing systems include hardware and software. The software part is mainly a warehouse management system, which manages and allocates information, resources, behaviors, items and personnel according to the business requirements of logistics and warehousing, so that they can operate efficiently and reasonably, and connects the entire system to the Internet; the hardware part Mainly the various hardware equipment and various Tools that support the warehouse management system.

The intelligent logistics warehousing system publishes cargo information to the Internet of Things. Within the entire scope of the Internet of Things, whether it is cargo information inquiry, cargo ordering, or cargo circulation, remote operation and monitoring can be easily performed. The steps for processing goods in the intelligent warehousing system are as follows:

① The warehousing process first uses RFID technology to verify the identity of the electronic tags of the warehousing goods, and transmits the information of the goods to the data center for cargo registration, calculates the shelf position and distribution route, and then sends the shelf instructions to the forklift to check the goods. Track and locate goods to ensure they are Stored in the correct warehouse.

② Inventory management, internal operation and processing of inventory goods, mainly including functions such as cargo guidance and arrival inspection, automatic identification of cargo locations and automatic quantity verification, correct allocation of warehouse areas, return processing, exchange processing, packaging processing and scrap processing.

③ Outbound process: First, the goods receiving personnel submit an outbound application to the warehouse information system. The intelligent warehouse management system queries the information and warehouse location of the goods according to priority, and then issues dispatch instructions to the forklift. After the forklift arrives at the warehouse to verify that the cargo information is correct, the transfer begins. goods. In each operating unit in between, the reader cargo information will be sent back to the data management center in time to determine whether the operation of each link is accurate.

Research on the structure of intelligent warehousing system

At present, there are demonstration cases of intelligent warehousing management systems based on EPC and logistics warehousing management systems based on WSN (such as ZigBee technology), but they are still far from truly meeting the requirements of "intelligence". For intelligent warehouse management systems based on EPC and mobile readers such as forklifts and handheld devices, a dedicated wireless transmission network must be built; for warehouse management systems based on WSN (such as ZigBee technology), due to the node cost ratio The EPC label is high, and the node size has not been truly miniaturized, so it cannot be attached to the surface like a label, which has a great impact on the movement of items.

The EPC-based intelligent warehousing system can be combined with WSN. The combined system uses WSN to transmit data from the EPC system and monitor the warehouse environment, such as temperature, humidity and light detection, and wireless video monitoring. WSN is an effective supplement to the EPC system, thereby making the entire warehousing system develop in a truly intelligent direction.

Summary

The Internet of Things and Intelligent Logistics and Warehousing Systems mainly studies and analyzes the Internet of Things based on the EPC Global architecture and its application in intelligent logistics and warehousing management systems, and proposes the idea of combining EPC Internet of Things and WSN to achieve complementary applications; The application prospects of the Internet of Things and smart logistics and warehousing are broad, and it will bring about earth-shaking changes to our production and life.
