1. Introduction to the system
For companies, important fixed asset management has always been a headache. Check the actual accounts; understand the configuration parameters of important assets at a glance; master the operation and maintenance of important assets. How to accurately and quickly grasp the relevant information is the problem to be solved by this system.
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 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.
Second, the system architecture
The system hardware architecture includes: fixed readers, antennas, RFID handheld devices, tags and back-end servers;
Data exchange method: It can be implemented in two ways, one of which is selected according to cost requirements:
Online data exchange, real-time transmission of field data back to the background information system for processing and analysis through a fixed reader/writer;
Offline data exchange, after collecting the data in the field through the handheld device, import it to the background information system for processing and analysis;
The overall system structure is: Multi-tire C/S combined with Browser/WebServer/DB Server;
3. Software system design
*System platform win2003+database;
*Software system function design;
Basic information management
Regional information, computer room information, cabinet information, coding rules, server information, printing styles;
system maintenance
*Data backup, operator, password modification, system log;
Computer room management
*Cabinet query, warehouse entry and exit order, warehouse entry and exit list, inventory, report center;
Server management
* Server increase, server decrease, usage, configuration list, report center;
Operation and maintenance management
*Server repair and regular maintenance;
*Handheld device data import;
Fourth, the server enters the computer room process
After querying the location 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.
Five, computer room inventory process
The person on duty in the computer room opens the system inventory interface and imports the inventory information to the RFID handset. 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 has 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.
Six, the main equipment of the system
UHF handheld series:
This product has the advantages of multi-protocol compatibility, multiple data interfaces, industrial-grade design (IP65), etc., and can be widely used in various RFID systems. Typical applications include:
Logistics and warehousing management: logistics industries such as item flow and warehousing management, as well as post office flow management systems for mail, parcels, and luggage transportation;
Supply chain application areas: application of goods supply process, etc.;
Product anti-counterfeiting detection: use the write protection function of the memory in the label to identify the authenticity of the product;
Other fields: in club management, library, student status, consumption management, attendance management, dining management, swimming pool management and other systems have been widely used.
Features:
It integrates an ultra-perfect combination of PDA and RFID data collection, and adopts a streamlined Windows CE embedded operating system, which can realize RFID data collection and storage functions;
Comprehensive functions, with Bluetooth, WIFI, GPS, GPRS (3G), two-dimensional bar code functions; (optional, users can choose whether to add these modules according to specific needs);
The appearance design is well applied with ergonomics, which makes you feel more when using:
Comply with ISM 860-960MHz (standard ISO1800-6B and EPC C1 GEN2 protocol)
Read and write tag ability: within 2 meters can read and write normally (depending on the card type)
