Analysis of the working principle and development process of RFID technology classification
Second, the significance of the application of RFID technology research
1. The application of RFID technology is an important measure to improve the management level of our military warehouse logistics system.
At present, our military warehousing system lacks macro management, warehouse management level is different, information construction standards are not uniform, and it is impossible to coordinate the overall situation, resulting in excessive inventory of a large number of combat general materials, resulting in waste of resources. At the same time, the standards for the construction of informationization of warehouses are not uniform, and there is no consideration from the perspective of the military logistics supply chain. Each unit has developed more software on its own, but it cannot communicate vertically. The use of unified RFID technology standards will help our military logistics management information resources to share and improve our military warehousing logistics management level.
2. Tracking research on RFID technology can realize real-time visualization of military material security
Ensuring the success of logistics support is the most important guarantee for winning the war. The informationized battlefield space is unprecedentedly broad, and the demand for logistical support is also unprecedented. The variety of materials involved is huge and the number is huge. The management of a large amount of military materials is an extremely arduous task, and it is impossible to track the location and status of materials in transit, but also to face the ever-changing security needs. Being able to accurately and quickly grasp inventory information and track the entire military logistics support process in real time is the key to solving the problem.
Through the research on the application of RFID technology, it is possible to establish a military logistics support system suitable for the future informationized battlefield, realizing the real-time visual management from the acquisition of battlefield demand information to the timely delivery of the required materials to the troops. Through the system, it is convenient to obtain the real-time demand information of the battlefield, the status of the materials in the way and the location information, etc., real-time tracking of the security materials, and provide auxiliary decision support for the development of the protection plan; at the same time, the military logistics command personnel can carry out the materials in transit through the system. Command and control to achieve redeployment of redundant materials on the battlefield. This is of great significance for improving the flexibility and rapid response capability of our military's military logistics activities, improving the command and control capabilities of our military's battlefield material support as a whole, and winning the future informationized war.
3. Greatly improve the economic benefits of military logistics support
The use of RFID technology to achieve automatic collection and rapid delivery of military material security information, greatly saving information processing time, enabling commanders to capture all the favorable fighters in a timely and ever-changing battlefield situation, to win the war and achieve the greatest military benefit. At the same time, the use of RFID technology makes the military logistics activities highly transparent, and the real-time information such as the position status of the military materials of the entire battlefield is unobstructed, which provides the necessary premise for the optimal configuration of the entire system, realizes the rational use of the entire battlefield resources, and minimizes the maximum. The waste of resources caused by the failure to keep up with the situation of the war, to achieve the greatest military economic benefits.
Third, the difficulties in the application of RFID technology in military logistics and the problems that need to be solved
Although RFID technology has a good application prospect in the field of military logistics, and has gradually begun to be widely used, there are still many factors that restrict the development and application of RFID technology.
1. RFID technology standard
There is a unique identification code in each RFID tag. If its data format is varied and incompatible, then RFID products using different standards cannot be used universally, which is very unfavorable for the circulation of items. At present, there are two coding systems for the application of RFID technology in the field of logistics: one is the UID coding system proposed by the UID Center of Japan, and the other is the EPC electronic product coding standard proposed by the American EPC (Electronic Product Code) Global Association.
More than 100 US and European distribution companies, such as Wal-Mart Chain Group, the world's largest retailer, and TESCO UK, are members of EPC, and are supported by technical research by IBM, Microsoft, and Auto-ID lab. There are currently no official international standards for RFID products, including individual frequency bands. At present, RFID products are incompatible with each other, resulting in confusion and incompatibility of RFID products in different markets and applications. This is bound to hinder the interoperability and development of future RFID products. How to make these existing standards compatible with each other, and to enable an RFID product to circulate smoothly around the world is an important and urgent issue at present, and it is also the primary problem that needs to be solved in the integration of military and civilian logistics.
2. The price problem of RFID technology application
At present, the price of electronic tags is relatively high in RFID systems. If each product is to be labeled with an electronic tag, then the cost of each electronic tag must be reduced to a certain price. It will take some time to achieve this goal. In addition, enterprises need to purchase a lot of card reading equipment and corresponding management software to apply RFID technology. Together with the related costs such as training, these investments are also very considerable.
3. Confidentiality issues in the application of RFID technology
With the application of radio frequency identification technology, many personal information of consumers may be illegally obtained. Therefore, the use of RFID has been opposed by some human rights organizations. At present, major RFID manufacturers are trying to find a solution. They try to make electronic tags After the goods are sold to consumers, they are automatically invalidated or encrypted to protect personal privacy. However, in the field of military logistics, the confidentiality requirements are quite high, which requires us to ensure information security in the process of developing RFID technology application systems. In the process of military-civilian integration guarantee, information must not be obtained or illegally used by the enemy, so as to avoid Make a huge loss.
4. Data processing capabilities of RFID technology applications
For enterprises using RFID technology, it is necessary to effectively deal with the huge data problems brought by the application of RFID technology, while improving production efficiency. Businesses need a data management platform that includes back-end databases, applications, and the right analytics to handle the vast amounts of data generated by RFID systems. In the development of military-civilian integrated logistics application system, RFID technology should fully consider this problem, ensure an optimized data management platform and powerful data processing capabilities, and provide real-time, fast and efficient logistics support for our military logistics. service.
Fourth, the application prospect of RFID technology in military logistics
Radio frequency identification technology has a good development prospect in the application of military logistics in our military. The application of RFID technology in military material security can realize the whole process of material security from the supply to the demand, realize real-time tracking and command and control of the materials in the battlefield, and improve the status of our military's material security, with the following aspects:
1. Speed up the speed of material security
The application of RFID technology realizes real automatic identification, does not require manual intervention, greatly speeds up the processing speed of various services, accelerates the transportation of required materials and supplies to the battlefield, and improves the emergency response capability of military logistics support.
2. Achieve complete visualization of the entire military logistics supply chain, eliminating excess inventory
The application of RFID technology not only greatly improves the management efficiency of various nodes in the military logistics supply chain (such as warehouses, distribution centers, etc.), but also realizes real-time tracking and monitoring of in-transit materials, so that logistics commanders can grasp the real-time logistics supply chain. Dynamic data enables complete visibility of the entire logistics system. Therefore, the conditions for the realization of joint stocks are created. The logistics command organization can arrange the warehouses in different regions to adjust the storage structure of the materials and eliminate the redundant stock reserves.
3. Realized the information management of warehouse management
The use of RFID technology in our military warehouse materials management can effectively solve the information management related to warehouse material flow, not only can grasp the relevant information of these goods, but also enable the warehouse to quickly and accurately understand its own inventory level and prevent the goods from being damaged. The loss and statistical errors lead to possible out-of-stocks. The use of RFID-based wireless technology can greatly improve the efficiency of cargo transportation, warehousing and inventory counting, and the entire delivery process does not even require human participation.
When the materials are installed through the RFID reader installed in the location, the inventory is automatically completed, and the wireless local area network transmits the data to the background management information system, and the command center can obtain the real-time material storage information. The use of RFID technology can also quickly and accurately locate a large number of materials and equipment to find urgently needed items.
4. Real-time tracking control of materials in transit
RFID technology is very convenient for tracking materials in transit, attaching telephone labels to military materials, setting up radio frequency information reading points along the material security, installing RFID information readers, and networking with the entire military logistics information platform. When the material reads the point through the information, the reader automatically reads the data from the electronic tag, and transmits the database of the in-transit material management system to realize information sharing. Let the commanders at all levels obtain the correct protection information in real time, and track, record and locate the movement of materials throughout the supply chain, so that the command organization can know the location and material status of the security materials on the entire battlefield in real time. It is also possible to monitor the full state of the security materials from the security zone to the demand zone in real time. Through the wireless command system, the command organization can also command and dispatch in-transit materials in real time according to the changes in the battlefield form, realizing the dynamic optimization of the battlefield resources, enabling the limited resources to exert the maximum guarantee potential and improve the efficiency of military logistics support.
5. Realize camp access control management
RFID technology can also be applied to military personnel and vehicle access management. An electronic label similar in size to a business card is attached to the windshield of a car or hung on a person. When a person or vehicle passes through the reader, the reader can quickly and accurately record the information of the passing vehicle and personnel. The time passed. At the same time, it is also possible to control whether or not to pass the door switch and strictly control the access control. Military and civilian integration military logistics has increasingly shown its importance, and RFID technology occupies a very important position in military logistics. With the gradual improvement and maturity of RFID technology, military logistics technology will inevitably achieve rapid development. It is bound to cause earth-shaking changes in our military logistics support, so as to better adapt to the needs of high-tech local war materials security
