RFID Management of Valuable Assets-RFID Management Information System for Computer Room Equipment
chrispeng [ad_1]
RFID is a kind of radio frequency identification technology, which is composed of readers, antennas and tags. When the tag is close to the sensing range formed by the reader and antenna, the tag will send the 96-bit data stored in the chip to the reader, and the reader will upload the data to the information system.
Due to the large amount of stored data, fast reading speed, and no need for human intervention in the process of reading data, RFID can perform rapid asset identification and inventory. Achieve accurate and rapid grasp of important fixed asset information.
The functional requirements of this system design are divided into three parts: system architecture, software system design, and hardware system design requirements
One, system architecture
The system hardware architecture includes: RFID handheld devices, tags and back-end servers;
Data exchange method: Two methods can be used, one of which can be selected according to the timeliness and cost requirements:
Online data exchange, real-time transmission of field data back to the background information system for processing and analysis through WIFI or GPRS on the handheld device
Offline data exchange, after collecting the data on the spot through the handheld device, import it to the back-end information system for processing and analysis
The overall system structure of the system is: Multi-tire C/S combined with Browser/Web Server/DB Server
2. Software system design
System platform win2003+ database
Software system function design
A. Basic information management
Regional information, computer room information, cabinet information, coding rules, server information, printing styles
B. System maintenance
Data backup, operator, change password, system log
C. Computer room management
Cabinet query, warehouse receipt, warehouse receipt, inventory, report center
D. Server management
Server increase, server decrease, usage, configuration list, report center
E. Operation and maintenance management
Server repair and regular maintenance
F. Handheld device data import
Three, business operation process
1 Encode the cabinet in the computer room, enter the coding information into the system and the RFID tag, and fix the RFID tag on the cabinet.
2 Encode the server, enter the encoded information into the system and the RFID tag, and fix the RFID tag on the server.

Server entering the computer room process: After querying the position of the cabinet in the computer room where the system server is placed, a list of production warehousing operations. The job list must at least include information such as the cabinet number and server number. The operation and maintenance personnel transport the server to the designated computer room according to the requirements of the operation list, and the personnel on duty in the computer room confirm the warehousing operation through the warehousing work order generated by the RFID handset. After the operation and maintenance personnel put the server in the designated location according to the requirements of the warehousing operation sheet, scan the cabinet number and server number through the RFID handheld to confirm that the operation is correct and complete the warehousing operation list. The staff on duty in the computer room confirms the cabinet number, server number and server location through the RFID handset to complete the warehousing work order.
Computer room inventory process: The staff on duty in the computer room opens the system inventory interface and imports the inventory information to the RFID handheld. The staff on duty first read the RFID tags of the cabinets for confirmation, and then read the tags of the servers in the cabinets in turn. If the tag data read in the cabinet is consistent with the inventory data imported to the handheld, the interface will be green, indicating that it is passed. If the inconsistent handset interface shows a red interface to indicate failure, you can choose to restart the inventory or end the inventory after checking. Finally, import the inventory data into the system.
