1. Warehousing and logistics operation control issues
In the traditional logistics system, warehousing operations have always played the most important role, but now that manufacturing technology and transportation systems have been quite developed, the role of storage operations has also undergone qualitative and quantitative changes. Although its original function of adjusting production and demand has not changed, in order to meet the small and diverse needs of the market today, the importance of picking, shipping, and logistics in the logistics system has been more important than the storage and storage functions. . Modern warehousing and logistics distribution must not only realize the storage function of the goods, but also have clear marks on the types, quantities, and owner storage locations of the goods in the warehouse. The stored goods should have clear upstream and downstream data in the supply chain. Connection, but also can realize the product information reverse check function. At the same time, prevent the massive appearance of illegal interests, counterfeit and counterfeit products, and guarantee the interests of consumers, users and manufacturers. Especially those special products and articles that are related to the national economy and people’s livelihood, such as railway materials, medical products and equipment, military materials such as guns and ammunition, and industrial pressure vessels such as liquefied gas cylinders. Once the products are counterfeited and unqualified, they will be brought to the society and individuals. An immeasurable loss. The production, circulation, use and maintenance of these special items require safer and more effective anti-counterfeiting and tracking protection measures.
2. Warehousing planning and product circulation management issues
Companies need to minimize the operating time of each order to meet customers’ increasingly complex and sophisticated product requirements and services, and at the same time, the prices that can be provided to manufacturers are constantly decreasing-this is a common problem faced by current manufacturers. In the warehouse operations of many companies, the problems they face are poor planning, unclear inventory, no pre-notification for receipt and delivery, and no automatic warning method for the upper and lower limits of inventory. Such problems have brought about changes in the implementation of warehousing operations. Requirements. In addition, it is necessary to prevent counterfeit and inferior products from being exiled to the market and continue to harm the interests of consumers, users and manufacturers. In response to the above problems, we used the advantages of RFID products in warehousing, logistics, and anti-counterfeiting control to integrate a set of “Product Warehousing and Logistics Management Solutions” that effectively control the entire process of products using RFID.
System solutions
1. System framework
The hardware network of the product sales chain logistics information system is composed of the local area network of the factory sales center and the dealer POS data collection terminal. The sales center local area network is composed of the center remote access server, the product logistics data dictionary database, and the sales chain logistics information management software function realization platform. The dealer visiting terminal POS terminal consists of a barcode scanner and a POS smart handheld computer (DRF).Please refer to the network structure diagram for the specific network composition
2. Data management
2.1 Basic data
Articles: name, type, packaging method, weight, measurement unit, production date;
Handling tools: forklifts, trucks (cabinet door open/close status information)
Packing: pallets, etc.
Warehouse area: area corresponding to the location label information
Controlling personnel: information of all authorized personnel, including truck drivers
2.2 Data management
Manage data
Comprehensive entry and exit management, location storage management, statistics, audit data, circulation chain data and audit information, etc.
Data relationship
The military supplies management information system is composed of three parts: the goods circulation process, the digital information collection, and the supervision and processing flow. And each data stream is constantly changing at each stage of the circulation of goods.
Item circulation process: refers to the entire process of items starting from storage to distribution and use;
Digital information collection: refers to the entire process of digital collection of items from storage to digital collection of goods receipt;
Supervision and processing flow: refers to the entire supervision and processing process from the entry of goods into the warehouse to the final warehouse.
2.3 Software function module
The system has gone through six links: planned production, warehousing, plan issuance, warehousing, transportation, and lower-level warehouse acceptance. The system is based on the security of goods and the continuous support of digital information collection to complete scientific and accurate processing.
According to the above data relationship, set up nine software function modules:
Product digital function module, warehousing and inventory early warning module, positioning management module, distribution management module, replacement and return module, settlement module, functional information (query, statistics, survey) module, as well as database access module and system maintenance module.

3.1 Product digitization
Product digitization: it is to establish a product code database, and correspond to each product or the electronic label with the product number and quantity written on the card board for storing the product;
The information in the database corresponding to the code should include: item name, type, packaging method, weight, measurement unit, production date, etc.;
The corresponding quantity of the names of the items stored on the card board is clearly stipulated.
Through the following process, a single product information can be read and written, and the corresponding product information can be written on the card board label:
3.2 Warehousing and inventory warning
Warehousing management: read the information of the warehousing items and store them in a designated place, and upload the product warehousing data to the designated database for storage;
Inventory warning: When the inventory quantity is lower than the set minimum allowable safety stock, the program will prompt the administrator to replenish the inventory in time.
3.3 Positioning management
Positioning management: store the goods in the warehouse through the RFID device identification area tag signal corresponding to the product number
In the database, it is easy to query and manage.
3.4 Distribution management
Distribution management: the entire circulation process of distributing military materials to designated places according to the plan.
The data can be managed by GPS/GSM in the circulation process to ensure the controllability of the whole process; after packing, in addition to writing the packing information into the container label, a fragile RFID tag is added as the box body. The seal, beware of tearing.
3.5 Make-up, return and exchange
Make-up, return and exchange: a series of tasks that need to be performed in the case of damage, overdue, insufficient quantity or wrong delivery of goods found in the process of delivery and use of the goods.
3.6 Settlement
Settlement: Settlement of military supplies is relatively simple, so I won’t describe it here.
3.7 Function information
Inquiries, statistics, surveys, etc., of all information on the items require authorized personnel to operate.
3.8 Database Access
Authorized personnel are required to operate, and the identity of the operator must be identified, and multi-level authorization can be set according to the needs of users.
3.9 System Maintenance
Authorized personnel are required to operate, and the identity of the maintainer must be identified, and multi-level authorization can be set according to the needs of users.
Below we elaborate on the general RFID management of military material inventory and flow.
3. Project requirements
RFID electronic tag is currently the most advanced non-contact sensing technology. It has a globally unique ID code, and has the characteristics of arbitrarily packaging, large memory, readable and writable, and anti-collision. It is suitable for automatic identification, data collection, and supply. Chain, retail, logistics, national defense and other fields. Especially in the management of military supplies, the application value of RFID is extraordinary.my country’s logistics information construction
A rational return from the “Great Leap Forward” craze of “catching up”, relying on mature and universal information technology is effectively improving internal inventory, warehouse positioning, and distribution security control management, effectively reducing some of the drawbacks of manual management .
Interpretation of the application of RFID in the field of Internet of Things
The use of RFID to manage munitions products needs to do the following:
1. The accuracy management of the inventory quantity of military supplies;
2. Inventory positioning management of military supplies;
3. Distribution management of military supplies;
4. Safety management during the distribution process.
2. Long-distance non-stop management system of RFID Internet of Things
1. Design principles:
According to our understanding of the design of the parking lot system, the following principles should be followed during the design process:
The management of the owner’s car mainly focuses on two points. First, the system should be able to facilitate the entry and exit of the owner’s vehicle, so that the owner can complete identification and parking deductions without getting off the car and reading the card. Second, the system should be able to accurately determine whether the vehicle has been paid for the current month. Rental of parking spaces.
Temporary vehicles: Because the charges for temporary vehicles are calculated based on the parking time, the control of the time period is a key to the management of temporary vehicles.
The parking lot system must ensure the safety of parked vehicles, and do not allow malicious driving of other vehicles out of the field.
The system design needs to consider the possibility of expanding into a one-card system in the future. If a unified RFID card is used, access control, attendance, meal sales, club consumption and parking lot management can be realized.
System design goals:
(1) The parking lot system design conforms to the national and Beijing parking lot management and charging standards.
(2) The system topology adopts the popular client server model, and the server is used to store on-site data.
(3) The intelligent process guides users step by step to complete the vehicle entry and exit and parking process, and prompts promptly for problems that occur during the entire process to ensure that the vehicle entry and exit are convenient and quick.
(4) High security: Different from the design of foreign parking lots, the system takes more into consideration the national conditions of our country, and focuses on strengthening the static and dynamic prevention of vehicles. The static part can be expanded with electronic code locks and alarm devices to prevent parking. Vehicles are monitored, and the dynamic part uses an image comparison system to complete the dynamic filming and comparison of images of vehicles entering and leaving the venue, which ultimately ensures the safety of the system.
(5) Vehicle protection function: The barrier automatically raises and lowers according to the traffic conditions of the vehicle, and has the function of anti-smashing, that is, as long as the vehicles entering and exiting the field are still under the barrier, the barrier will keep its initial state and fall.
(6) The parking fee is calculated and confirmed by computer, which eliminates errors and cheating caused by human operation and protects the interests of investors.
(7) The method of combining computer network and charging software prevents illegal modification or unauthorized access to information.
(8) The management computer and each charging computer can realize real-time monitoring, and the management computer has an external interface, and the network is extensible.
(9) The standard industrial control system structure is adopted, and the configuration of different systems can be organized according to the different requirements of users, which is convenient and flexible.
Installation, debugging and maintenance are simple and convenient, easy to replace and overhaul.
