Logistics is a very important link in the supply chain of commodity circulation and occupies an important position in the national economy, while warehousing is the core link of modern logistics. In the process of warehouse management activities, a large amount of warehousing information will be generated. This information is often generated with the occurrence of warehouse orders, goods storage, goods management, and goods export.
Generally, it has the characteristics of frequent data operations, large amount of data and complex information content. Efficient and reasonable warehousing can effectively control and manage the goods. How to reduce inventory investment, strengthen inventory control and supervision, increase the utilization rate of space, personnel and equipment, and shorten the storage and delivery procedures and inspection time are the keys to enterprises to reduce costs and improve their competitiveness.
The development of warehousing has gone through three stages of development: 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 decision-making systems and the use of radio frequency technology have enabled warehousing to develop in the direction of intelligence. 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.
Methods of logistics warehouse management
1. Applying hardware equipment to the logistics process The Internet of Things is a manifestation of the Internet’s application in the logistics and warehousing industry, which 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 warehousing time, delivery location and other information of all the products in stock in detail, and to perform barcode and QR code pasting to facilitate the information inspection of the product. Reduce the complexity and difficulty of follow-up work.
At the same time, information readers should be placed at the entrance and exit of the warehouse and connected to a computer in order to grasp and record information in a timely manner, to ensure the circulation of information, to facilitate the regulation of various products, and to improve work efficiency.
2. The logistics management technology oriented to the Internet of Things must ensure that the logistics warehouse work is carried out in an orderly and efficient manner, and requires cooperation and communication among various departments in all links. When the product is in and out of the warehouse, it is necessary not only to read the product information, but also to manually check and confirm the product to improve the accuracy of the work. During the inspection process, it is necessary to ensure that the product network and document information are consistent with the actual situation, and to check whether the product is damaged or not. Once problems are found, contact the merchants in time to communicate and solve them together to ensure the quality of the goods in the warehouse.
The staff responsible for overall control should enter relevant information into the computer, and ensure that the database is updated in time, clarify the time of entry and exit of the goods and the nature of the product, and classify and place the information according to the similarities and differences during the handling process, so as to Efficient development of follow-up work. When checking the products in the warehouse, download the data and information in the warehouse in advance to ensure the completeness of the information of each product, and the staff will use the mobile terminal to scan the product barcode and check the information again. Once there is a problem, report to the warehouse in time Administrators, and conduct a second check to make up for loopholes and ensure product safety and information accuracy.
When the products are shipped out of the warehouse for distribution, the management personnel must use professional mobile terminals for further verification and inspection of the products involved. And when going out of the warehouse, the brand and quantity of the goods out of the warehouse are counted through the handheld mobile terminal to generate out-of-warehouse information, and the out-of-warehouse information is compared with the table of the outgoing goods to check whether there are any omissions. In addition, generating product information on the Internet of Things can facilitate inquiries between manufacturers and purchasers. By scanning the QR code to enter the website to perform product inquiries, the safety of the product can be guaranteed.
Smart logistics warehousing system processing steps
The intelligent logistics warehousing system must not only be able to carry out inbound management, outbound management, movement in 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. Carry out video surveillance and fire alarm for the warehouse.
The intelligent logistics warehousing system includes two parts: hardware and software. The software part is mainly the warehousing management system, which manages and deploys information, resources, behaviors, items and personnel in accordance with the business requirements of logistics and warehousing, so that they can operate efficiently and reasonably, and the entire system is connected to the Internet; hardware part Mainly support the various hardware equipment and various tools of the warehouse management system.
The intelligent logistics warehousing system releases cargo information to the Internet of Things. Within the scope of the entire Internet of Things, whether it is cargo information inquiry, cargo ordering, or cargo circulation, remote operation and monitoring can be conveniently carried out.The processing steps of goods in the intelligent warehousing system are as follows:
①The warehousing process, First, use RFID technology to verify the electronic tag identity of the goods in the warehouse, and transmit the information of the goods to the data center for goods registration, calculate the storage location and distribution route, and then send the loading instruction to the forklift to track and locate the goods. To ensure that the goods are stored in the correct position.
②Inventory management, Internal operation processing of inventory goods mainly includes functions such as goods guidance and in-place inspection, automatic identification of goods location and automatic quantity verification, whether the allocated warehouse area is correct, return processing, exchange processing, packaging processing and scrap processing.
③The outgoing process, First, the picking staff submits an outbound application to the warehouse information system. The intelligent warehouse management system queries the information and storage location of the goods according to the priority, and then sends a dispatching instruction to the forklift. After the forklift arrives at the storage location, it starts to transfer the goods. In each operation unit in between, the reader cargo information will be sent back to the data management center in a timely manner to determine whether the operation of each link is accurate.
Research on the Structure of Intelligent Warehousing System
At present, there have been demonstration cases of intelligent warehouse management systems based on EPC and logistics warehouse management systems based on WSN (such as ZigBee technology), but they are still far from achieving the requirements of “intelligence”. For EPC-based intelligent warehouse management systems and mobile readers such as forklifts and handheld devices, it is necessary to build a dedicated wireless transmission network; for warehouse management systems based on WSN (such as ZigBee technology), due to the node cost ratio The EPC label is high, and the volume of the node has not really been miniaturized, so that it cannot be affixed to the surface like a label, which has a great impact on the movement of items.
The EPC-based intelligent storage 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, so that the entire warehousing system develops in the direction of true intelligence.
summary
The Internet of Things and Smart Logistics Warehousing System mainly researches and analyzes the Internet of Things based on the EPC Global framework and its application in the smart logistics warehousing management system, and puts forward the viewpoint of combining EPC Internet of Things with WSN to achieve complementary applications; The Internet of Things and smart logistics and warehousing have a broad application prospect, and they will bring earth-shaking changes to our production and life.
