Demand analysis
The development of computer network technology and modern communication technology has provided conditions for high-speed and accurate data transmission on a global scale, and has also brought opportunities for the widespread application of RFID technology in the logistics industry (mainly in the supply chain). In fact, the transportation and logistics industry has always been a typical application field of RFID technology. In essence, the reason why RFID technology (especially the UHF part) has produced such a enthusiastic response in such a wide range at home and abroad is also the earliest rise of the logistics industry. . The supply chain we usually refer to refers to the movement process of all physical objects from raw materials to end users. Including supplier selection, purchasing, product planning, material processing, order processing, inventory management, packaging, transportation, warehousing and customer service. Today, the supply chain has become a key area of competition among enterprises, and the integration and management of the supply chain also means that enterprises will face a series of new technological challenges. Factors such as intensified market competition and variability in demand urge product production and sales traders to continue to accelerate their pace, introduce personalized and flexibly configurable products, ensure promises, deliver on time, and quickly respond to the changing requirements of customers , Hobbies and the external economic competition environment. In supply chain solutions, speed, efficiency, accuracy, and information integration are the key goals pursued by the program.
The advancement of RFID technology lies in the use of radio waves to simultaneously transmit identification information in a large number of non-contact, long-distance, and dynamic multi-targets, realizing a true “one item, one code”, and rapid item tracking and data exchange. Because RFID technology eliminates manual intervention in the tracking process, it can greatly improve work efficiency while saving a lot of manpower and material resources, so it has great appeal to logistics and supply chain management. Not only that, the combination of RFID technology and computer and communication technologies such as Internet, GPRS, CDMA, etc. can form a global industry management network, realize cross-regional and cross-border identification and tracking of items, and realize international circulation. The application of RFID core technology in the field of logistics and supply chain can not only break through the “bottleneck” problem of bottom-level data collection in the field of logistics, improve the level of automated processing in all aspects of logistics activities, improve logistics efficiency and accuracy, and reduce logistics costs. Solve the problems of out-of-stock, theft, and the loss of supply chains in the retail industry.
According to an authoritative analysis, the revenue of retailers from adopting RFID technology will come from three aspects: ①The reduction of inventory, one-time savings in cash amounting to about 5% of the total inventory. ②Reduce warehousing and warehouse labor costs by 7.5% every year. ③The number of out-of-stock products decreased. Due to the reengineering of business processes brought about by RFID, retailers will generate a continuous income of 700,000 US dollars for every 1 billion US dollars in annual sales. Of course, judging from the current status quo, the application of RFID is still limited to enterprises. Because the application of RFID in the logistics industry involves the entire process of the supply chain, including logistics and distribution companies, customs, industry and commerce, taxation and other links, there are still many connection problems that need to be resolved. In addition, the price, privacy protection, and security issues of large-scale RFID applications cannot be ignored. Precisely because of the aforementioned problems, most of the application projects of RFID technology in the logistics industry and supply chain are still in the testing, adjustment and standardization stage, and there is still a long way to go before the true mass integrity application. However, focusing on the extremely broad market and extremely attractive business prospects, major RFID manufacturers and logistics service providers at home and abroad have never stopped the tentative application of RFID technology in this range. In the past few years, most of the applications in this area have been implemented around passive UHF technology. Under normal circumstances, the stable reading range of passive technology is about 3-5 meters, which is full of various information reading obstacles in the usually dense metal working environment, and it is difficult to meet the applications in various harsh environments. need. Correspondingly, the outstanding advantages of active tags in effectively coping with harsh working environments, long-distance reading ranges, and large-capacity user-available memory have made some large-scale test applications in recent years gradually move closer to them.
Based on the deep active RFID technology foundation, Shanghai Boao Electronic Technology Co., Ltd. has launched a series of products in logistics and supply chain applications, providing high-cost front-end collection equipment for domestic and foreign logistics and supply chain management service providers. In recent years, after a series of technological innovations, Boao RFID technology and products have been substantially improved, completely solving the identification and data transmission problems of long-distance, large-flow, ultra-low-power, high-speed moving markers, and cost It is greatly reduced compared with the past, and will provide high-quality technology and product solutions for logistics and supply chain applications.
application solution
In practical applications, electronic tags are usually affixed to the packaging boxes or pallets of each group of goods, and specific information such as the name and specifications of the goods, storage location and other information are written in the labels. At the same time, the detailed information of the delivery party can be written when the goods enter and leave the warehouse, and fixed or hand-held readers are installed in the warehouse and various distribution channels to identify and detect the flow of goods. In the entire link of the supply chain, including procurement, storage, manufacturing, packaging, loading and unloading, transportation, circulation processing, distribution, sales and service of various business links and processes, electronic tags play the role of the most basic information carrier.
(1) Yard management
Yard management is one of the links in the domestic supply chain management where the use of RFID technology can significantly improve efficiency, because the space of the yard is often extremely limited. If the frequent container in and out and stacking operations are handled in this limited space, it is a problem. Major test. Since the introduction of the RFID system, some large domestic storage yards have achieved remarkable results despite many shortcomings. The typical RFID yard application process is as follows:
When a new container arrives, the trailer driver hands the delivery list to the yard management center for processing. The management center enters the relevant information of the container in the office system, such as the container owner, type, size, container number, etc., and calculates an optimal stacking location for the container according to the current stacking status of the yard and the stacking rules of the container. At the same time, an RFID tag is issued and associated with the information of the box and installed on the container. At the same time, the warehousing information is transmitted to the forklift in the yard through wireless communication. The forklift driver can know what kind of truck is going to send what kind of cabinet to where. When the trailer reaches the designated position, the forklift grabs the container, and the on-board RFID reading device installed on the forklift will read the tag signal installed on the container and compare it with the previously received container information. If it is consistent, then The forklift driver can put the cabinet in the designated location and confirm to the management center that the previously designated cabinet has been stored in the location; if it is inconsistent, an error message will be sent to the management center. The management center adjusts according to the error situation until the designated cabinet matches the designated position. After completing the storage operation, the tow truck driver can drive the car directly out of the gate.
If the newly arrived container has an electronic tag installed, the yard management center can directly write the location information into the electronic tag and wirelessly send this information to the forklift’s LCD screen for subsequent related operations.
When an empty trailer arrives at the yard to pick up a container, the trailer driver will hand over the packing list to the management center for processing. The management center enters the information on the packing list, and calculates the position of the packing box and the box number of the box from the system according to the owner, type, size, etc. of the container. And tell the driver to drive the trailer to that location. At the same time, through wireless communication, the suitcase information is sent to the forklift. Let the forklift driver know in advance what kind of truck is going to pick up what kind of cabinet. When the trailer reaches the designated position, the forklift driver picks up the cabinet from the designated position. At this time, you can read the RFID attached to the cabinet through the RFID reader on the forklift, and verify that the container numbers are consistent. If they are consistent, put them on the trailer; if they are inconsistent, send an error message to the management center and let the management center modify the corresponding work instructions until the specified container number exactly matches the specified location. After the trailer picks up the box and arrives at the gate, the RFID reading system installed at the gate reads the RFID tag on the container, and the exit system shows that the box should be picked up by that vehicle. If the license plate displayed on the system is consistent with the actual license plate of the vehicle, press the “release” button, and the gate management personnel will remove the label on the cabinet and let the vehicle go out; otherwise, return to the storage yard for adjustment until the specified cabinet is consistent with the specified The license plates match exactly. After the lifting operation is completed, the yard management personnel can inquire about the box number, location, etc., and the updated yard stacking situation.
(2) Mobile asset management
Effective management of mobile assets in all aspects of logistics (such as trailers, forklifts and tugs, etc.) will significantly reduce labor intensity and improve operational efficiency. These assets need to be queried in real time to their exact location (in the warehouse or in the yard) so that they can be quickly deployed in the subsequent operation process. In addition, the industry is also establishing a monitoring system for these mobile assets to facilitate the asset safety management of these mobile assets, and in specific matters, suitable mobile assets can be designated for corresponding business operations. RFID technology is to achieve this supervision. The best choice for your needs. In addition, these mobile assets usually need to establish their own operation and maintenance files so that the supervisory department can understand their usage and repair and maintenance status.
(3) Warehouse management
Warehouse management based on RFID technology is the introduction of RFID technology into existing warehouse management, which automatically collects data from various operations such as warehouse arrival inspection, warehousing, outgoing, allocation, shifting, and inventory counting. To ensure the speed and accuracy of data collection in all aspects of warehouse management, to ensure that the company can timely and accurately grasp the real data of the inventory, and reasonably maintain and control the company’s inventory. Through scientific coding, it is also convenient to manage the batch and shelf life of items. Using the system’s location management function, you can also grasp the current location of all inventory materials in a timely manner, which is conducive to improving the efficiency of warehouse management.
In practical applications, the warehouse management system based on active RFID technology can basically achieve the level of large packing boxes. When entering and leaving the warehouse, the electronic tags attached to the packing boxes can be automatically read by the reader placed at the door of the warehouse. And transmit relevant information to the background management system to ensure that the data can be updated in real time and to ensure that the items are placed correctly. Sometimes, in order to better monitor the storage environment of items, active tags also integrate related sensors (such as temperature, humidity, noise and vibration, etc.) to monitor changes in the surrounding environment.
(4) Regional positioning management
Realizing the real-time positioning of some important assets (products) in a wide area is essential for improving work efficiency and reducing labor costs. In some large equipment production bases (such as automobiles, train cars, etc.), the appearance of the products is very similar, and it is very laborious to find them.
Readers and tags based on active RFID technology can communicate freely within a range of up to 80 meters, and can quickly reflect the movement of the target asset and the current area to the back-end system for users to find. The reader can divide a large area into grids, combined with the GIS system, can quickly identify these assets, and quickly deploy follow-up operations when needed.
(5) Asset monitoring and management
Boao RFID technology can realize the information flow management of items in the entire supply chain. The user capacity of active electronic tags up to 32KB can record all relevant information in the entire chain process, and track and monitor the entire process of asset circulation, which makes it play an important role in handling some assets such as asset leasing and debt disputes.
Another important role of active tags in asset monitoring and management is to ensure that authorized persons can operate/use these assets. In some of the more important asset monitoring applications, the arrival of an asset in a certain place does not mean that it can be used at will. Only those who are authorized can open and use these assets. Or, although these assets can still be used freely, all usage conditions will be recorded in detail, and these records will be automatically uploaded to the central control system when approaching the reader.
In practical applications, active tags may integrate some safety demonstration functions and try to be impeccable in safety logic demonstrations. A similar example is the application of our company’s electronic lock products in SAIC’s vehicle distribution. Of course, the electronic lock here is considered as a special active tag.
