1 System overview
At present, RFID technology is bringing a huge change to the supply chain field, to identify the incomparable advantages of long distance, fast, hard to damage, large capacity and other bar codes, simplify the complicated work process, and effectively improve the efficiency of the supply chain. Beijing Dingchuang Hengda Intelligent Technology Co., Ltd. conducts in-depth analysis and research on current warehouse management technology, introduces RFID technology, and develops a warehouse management system based on RFID technology. Automated data collection of the data of each operation link such as warehouse arrival inspection, warehousing (return), outbound (lending), allocation, shifting, inventory counting, etc., effectively ensuring the speed and speed of data input in each link of warehouse management accuracy. If the item (out of the warehouse) is registered on the computer first, the administrator only needs to use RFIDHandheld TerminalScan the goods, and then use the computer to confirm the delivery. Greatly improve work efficiency and data accuracy. While maintaining the advancement and safety of the warehouse management system, this system also provides a third-party interface for customers to interface with other software.

PC software function diagram of emergency equipment warehouse management system (3-1-2)
The PC-side software of the emergency equipment warehouse management system includes: basic data management, emergency equipment management, process management, statistical query, temperature and humidity query, and system management.
3.1.1 Basic data management
Equipment management is mainly used for operations such as storage, delivery, maintenance, and scrapping of equipment. After the application form is submitted, the approver will review and approve. If the approval is passed, you can enter the corresponding management page to enter and leave the equipment operate;
Equipment file management
Manufacturer file management
Subordinate organization management
Personnel management
Inventory warning
Job management
3.1.2 Emergency equipment management
Video shooting and timely alarming of fixed asset loss, unauthorized dismantling, and unauthorized movement in the supervision area, to ensure asset safety, reduce losses, and ensure that asset problems are based on evidence;
Warehouse management
Outbound management
Maintenance storage management
Maintenance out of warehouse management
Maintenance storage management
Maintenance and outbound management
Loan management
Return management
Scrap management
3.1.3 Process management
Process management is to set up the workflow, and authorize the approvers or roles who can view the application form;
3.1.4 Statistics query
According to customer needs, the equipment information, equipment usage, or current status of equipment can be queried;
3.1.5 System Management
System settings and management of system user information and permissions.
User Management
Node management
Role management
Dictionary maintenance
3.2 WEB remote management terminal
The WEB remote management software includes: warehousing application, approval warehousing application form, approval query, and process setting parts.
3.2.1 Application for warehousing
The warehouse application function is to make an application form for the equipment to be warehoused, add the equipment to the application form and fill in the quantity and submit;
3.2.2 Approval of the warehousing application form
Approval of the warehousing application form is mainly used for the function of approving applications by persons with approval authority. The approval authority can be authorized through process management;
3.2.3 Approval query
Can query the approval status and completion status of the application form;
3.2.4 Process settings
The main function of the process setting is to design the approval process of the manifest, which can add or delete the approval link and authorize the approver of each link.
3.3 PDA software

3.3.1 Inbound management
Generate the warehouse receipt on the PC side. The RFID handheld terminal can synchronize the PC-side information to the RFID handheld terminal via WiFi. The RFID handheld terminal searches for the equipment according to the warehouse receipt. If it is the equipment of the warehouse receipt, the RFID handheld terminal page Display the correct information in green, otherwise the equipment information will not be displayed;
3.3.2 Inventory management
Use the RFID handheld terminal (DC-0671A) to carry out the inventory operation of the equipment in the warehouse. The system can generate an inventory task table according to the pre-set query conditions, and perform inventory operations based on this table. The inventory operation mainly scans the RFID tags bound to the equipment information;
3.3.3 Write label
Tag writing is the process of automatically generating a tag number based on the information in the warehousing list and then writing the tag number into the RFID tag to realize the process of binding the RFID tag to the equipment.
4 System characteristics
System utilizationRFIDTechnology realizes remote control, better, safer and more accurate supervision of equipment;
The user can check whether the equipment is loaned or returned, whether it is alarmed, etc. in real time, so that the user has a more intuitive visual status, which is more convenient and faster than the previous equipment management;
The equipment is easier to manage, improving safety and confidentiality.
The most economical solution in a completely non-contact system: embedding a non-contact chip into a low-cost medium can meet the needs of the solution to the greatest extent. The application of this advanced technology can greatly reduce equipment investment and maintenance costs. The cost of hardware wear and tear.
The combination of wifi technology and RFID handheld terminal realizes the functions of outgoing, storing, and querying equipment;
Fast scanning, barrier-free reading: RF, ID tag scanning, there is no need to align the reader in a straight line, and the reading and writing speed is fast. At the same time, RFID uses radio waves to transmit information, and there is no transmission barrier problem.
The system provides a variety of flexible third-party interfaces to seamlessly connect with third-party application systems.
