1. Introduction to the system
Establish an advanced RFID application system in the key links of asset management to improve the informatization, automation, networking, and intelligence of asset management. At the same time, in asset management, the contract management of the asset management department is realized, which is convenient for the asset management department to count the asset reconciliation data in real time and accurately.
The goal of this system is to rely onRFID The technical advantage of the company is to use advanced RFID equipment to automatically collect data through the tags placed on the assets, and to quickly realize the management of the assets through the intelligent decision-making of the back-end application software. Through the query system, the status of each asset and the whereabouts of the assets can be clearly checked, and the information about the whereabouts of the equipment can be recorded in time. During the asset inventory, it can effectively reduce the labor intensity of employees and maximize the efficiency and accuracy; realize the asset management department The contract management is convenient to find the corresponding relationship between the contract and the asset, to increase the management pertinence of the asset from the management, and at the same time to cooperate with the management level of the material management department to establish the application of scientific management to improve the new image.
2. Model system structure diagram
The fixed asset management system based on RFID technology designed in this article is designed to realize the automatic supervision and alarm of various management processes, improve the level of security, and facilitate the management of statistics, inquiries and grasp of the real-time status and use of assets. If the documents that have not been passed or allowed are taken out, the system can carry out the alarm function.

3. Processing flow
Data collection layer: This layer is directly connected with each RFID card reader to collect the data returned by the card reader.andCard readerAll data interactions in this layer are filtered before being passed to the database layer, which can reduce the redundant data of the database and reduce the burden on the management application layer.
Database layer: SQL SERVER database system is adopted, which can accurately save large-capacity data in real time. Set up data security and backup mechanisms at the same time.
Management application layer: This layer is the main application presentation layer of the system, and all functions that directly interact with management users are distributed in this layer. Including system management, RFID tag management, personnel management, asset management, query statistics, etc.

5. The effectiveness of the RFID asset supervision system
(1) Realize “asset life cycle management” and “asset automatic management”, realize the intelligent dynamic real-time tracking and centralized monitoring and management of the asset life cycle (new addition, allocation, idle, scrap, maintenance, etc.) process. The management process does not require any manual intervention.
(2) Provide accurate reference data for management to provide decision-making and reasonable asset allocation, effectively increase the marginal benefit of investment and increase the utilization rate of assets, and reduce unnecessary equipment investment and idle waste.
(3) Save the cost of manual data collection; reduce inventory by 10~30%; increase the utilization rate of inventory space by 20%, and truly realize paperless/addressed asset management: the system uses IP access addresses, and users can use IE browsers anytime, anywhere Access the system.
(4) Automated asset management operations improve work efficiency; reduce labor costs by 10-40%;
(5) Reduce management costs and human errors;
(6) More precise control and management of exit, entry, and storage; reduce losses due to wrong collection and improper storage.

7. System advantages
(1) Install RFID readers, antennas and other equipment concealedly through customized stainless steel boxes;
(2) All products are independently developed by the company to ensure the convenience of later maintenance and interface customization;
(3) Multiple clients collect data, receive and process data in real time;
(4) It can dynamically monitor the flow of unauthorized assets.
8. System security
(1) The entire system has the characteristics of long-distance rapid identification, high reliability, high confidentiality, easy operation, and easy expansion. The asset identification system can operate independently and does not depend on other systems.
(2) The internal data of the tag adopts a special encryption algorithm to ensure that the EPC tag has a security function to prevent illegal writing and reading.
