Intelligent logistics
Intelligent logistics is a complex system. Including transportation, containers, warehousing, ports, platforms, shelves, to all possible personnel and information exchanges in the logistics chain, and integrated management that integrates related activities in the logistics chain. Through intelligent hardware, Internet of Things, big data and other intelligent technologies.

Application of VR technology in logistics system
VR technology involves computer graphics, sensor technology, human-computer interaction technology, artificial intelligence and other fields. It is a technology that uses a computer system to construct a realistic threedimensional space through certain instruments and equipment. Users can achieve the integration of visual, tactile, auditory and other aspects with the presentation screen by wearing VR helmets, headsets, and holding data controllers, so that they can produce an immersive feeling. The user in the experience is not only A third party in the bystander position can also operate the scene in the threedimensional space through data handles and other equipment. The things in the scene will also respond accordingly to the user's actions or operations, which is a kind of feedback , New technology with strong interactivity. The introduction of VR technology in the training of new employees and new skills can reduce costs, improve training efficiency, and greatly shorten the time on duty. VR realistic logistics environment, such as warehouse layout, logistics equipment, port logistics, roaming logistics park, etc., employees are immersed in In the real logistics work scene generated by virtual simulation technology, experience, feel and interact actively. VR technology is applied to the logistics training industry. The application of VR technology is shown in Figure 1.

Application of Internet of Things in Logistics System
With the advent of the era of the Internet of Everything, the logistics industry is gradually developing in the direction of intelligence, and the Internet of Things plays an important driving role in the intelligent development of the logistics industry. The core of logistics is the flow of goods or commodities, and the Internet of Things focuses on things. After identifying and collecting a large amount of object information through a variety of sensing technologies, it connects various object information data to form a data network. Then use cloud computing, big data, edge computing and other technologies for intelligent processing, Realize the intelligent connection of things, so it has high applicability in the logistics field, and can further strengthen the monitoring of items in warehousing, transportation, distribution and other links, accelerate the speed of obtaining item status information, improve the level of item safety management, and improve the efficiency of logistics operations. The business application of the Internet of Things in logistics companies is shown in Figure 2.

Intelligent logistics system
The Intelligent logistics system includes 5 levels horizontally, and 5 levels cover Full Chain, Full Channel, Full Scene, Full Technology, and Full Goal. According to the direction of goods circulation, it is divided into TOA Stage (commodity production), TOB Stage (commodity circulation), and TOC Stage (commodity consumption). The personnel covered by the system include: Raw material supplier, Manufacturer, Regional Agent, Retailer, E-commerce Platform, User, Intelligent logistics system uses technologies including Big data, Internet OF Things, AI, Blockchain Traceability, Cloud Computing. The architecture of the intelligent logistics system is shown in the figure 3.

Application of Intelligent logistics system
The realization of smart logistics can greatly reduce the transportation costs of various related industries, improve transportation efficiency, and enhance corporate profits. The Internet of Things is applied to three aspects of the logistics industry, namely, cargo warehousing, transportation monitoring, and smart express terminals.

Cargo storage
In traditional warehousing, manual cargo scanning and data entry are often required, which results in low work efficiency. At the same time, storage locations are sometimes unclear, stacked in confusion, and lack of process tracking. Applying the Internet of Things technology to traditional warehousing to form an intelligent warehouse management system can improve the efficiency of goods in and out, expand the storage capacity, reduce labor intensity and labor costs, and can display and monitor the in and out of goods in real time to improve delivery Accuracy, complete the tasks of receiving goods into storage, inventory allocation, picking out of storage, as well as data query, backup, statistics, report production and report management of the entire system.

Transport monitoring
Real-time monitoring of transported trucks and goods through the logistics vehicle management system can complete real-time, positioning and tracking of vehicles and goods, monitor the status and temperature and humidity of the goods, and monitor the speed of transport vehicles, tire temperature, tire pressure, fuel consumption and fuel consumption , Vehicle speed and other driving behaviors such as the number of brakes and driving behavior, in the process of cargo transportation, the information such as cargo, driver and vehicle driving conditions are efficiently combined to improve transportation efficiency, reduce transportation costs, reduce cargo losses, and clearly understand transportation Everything in the process.

Smart express cabinet
The smart express cabinet is based on the Internet of Things technology, capable of identifying, storing, monitoring, and managing objects. Together with the PC server, it forms an intelligent express delivery system. The PC server can process the information data collected by the smart express terminal and update it in the data background in real time, which is convenient for users to query express delivery, deploy express delivery, and express terminal maintenance.

New employee training
The introduction of VR technology in the training of new employees and new skills can reduce costs, improve training efficiency, and greatly shorten the time on duty. VR realistic logistics environment, such as warehouse layout, logistics equipment, port logistics, roaming logistics park, etc., employees are immersed in In the real logistics work scene generated by virtual simulation technology, experience, feel and interact actively.

CONCLUSION
We chose the Lehua Logistics Base of Nanchang Section of Beijing-Kowloon Railway to apply the intelligent logistics system and select 6 common goods. The annual revenue of the system was 3.63 million yuan before the system was used, and 4.28 million yuan after the use. The annual revenue growth rate is 15.19%, as shown in Figure  4. The introduction of the smart logistics system accelerates the flow of corporate goods, reduces labor costs, and significantly improves corporate profits.
