1. System overview
Asset management currently relies on traditional manual management methods and means. Data collection and entry have always been manual operations, which are inefficient and high in error rates, and asset physical information and management system information cannot be synchronized in real time. As a bridge between the physical world and the existing IT system, RFID technology can effectively integrate the daily asset management activities with the asset management system, so as to achieve real-time synchronization of physical information and system information.
The new technology of RFID realizes remote, dynamic and real-time equipment asset data collection, replacing the front-end manual data collection of traditional asset management methods, and better combining with back-end computer databases.
Realize real-time monitoring, recording and automatic update of information such as asset addition, allocation and inventory in daily management, and collect personnel information at the same time, so as to avoid the reduction of management efficiency due to information distortion caused by human factors, and provide unit leadership and network planning Investment and design departments provide more accurate and real-time physical information of network assets, improve asset utilization efficiency, effectively reduce and control daily management and production costs, and create good social and economic benefits.
2. System flow and principle
The RFID automatic identification system is responsible for the automatic collection of operator information, asset changes, and inventory information, and uploads the information to the management center asset management auxiliary system server through the RFID handset, as a data source for updating the database and other system applications such as MIS and EMIP. Enable managers to keep abreast of asset allocation and completion of work orders in a timely manner to achieve effective supervision of daily management work, thereby improving work efficiency.

RFID hardware includes reading and writing equipment, metal electronic tags, etc. It is planned to implement the system from the following aspects to realize the automatic collection and monitoring and management of accurate information of the entire process of assets, and to realize the sharing of various information and data.
(1) Personnel information management: Each on-site operator holds a work card corresponding to the staff information, and realizes automatic monitoring and management of personnel operation information.
(2) New equipment management: create electronic label information files for newly purchased equipment, assign electronic labels to equipment and personnel through card readers, associate electronic label ID numbers with equipment and personnel information and import them into the database, electronic labels Paste it on the corresponding device panel, and assign the personnel management card to the personnel.
(3) Equipment real-time allocation management: equipment purchased becomes an asset. After it is put into use, there will be normal allocation, maintenance, and scrapping operations. Before allocation, read the operator card information or warehouse card information through the RFID handset, and enter Read the electronic label information on the asset when it is transferred in, and read the electronic label information on the asset when it is exported, and transmit the label information including the operator, time and other information to the central server to automatically process and determine the equipment Status, complete real-time tracking and positioning management of operator information and assets.
(4) Equipment inventory management: read the operator card information and base station card information through the RFID handset before inventory, and then download the list of equipment classification information that needs to be inventoryed from the server through the GPRS network or the handset data line, and then use the handset to collect The current equipment information in the base station is compared and processed, and relevant alarms and treatments are provided for the inconsistency of the accounts. Finally, the asset inventory profit and loss results are automatically generated, including the operator, time and other information and uploaded to the asset management system , And use this to update the relevant information of the corresponding assets in the back-end database.
2.3 The working principle of the system
Each asset is attached with an electronic tag with a unique ID number. When the asset enters the RFID handset antenna identification area, the antenna activates the electronic tag circuit by sending a microwave signal, and at the same time, the electronic tag sends an echo signal, and the two conduct two-way data exchange , The reader obtains relevant information, and at the same time uploads the asset-related information to the RFID system server in real time, performs corresponding format conversion, filtering and related subsequent statistical processing, as a data source for other systems to realize relevant data statistics, query and other functions, Realize the real-time monitoring, recording and automatic update of change information in the daily management of assets.
3. System highlights
The application system uses the latest international automatic identification technology-radio frequency identification technology (RFID), and uses modern computer technology, communication technology, automatic control technology and other technologies to comprehensively realize automatic asset identification, informatization and intelligent management. The features of the system are as follows:
The RFID handheld machine integrates functions such as electronic tag reading and data processing.
High-secret asset files, strengthen equipment supervision through high-tech, rationally allocate resources, reduce resource waste, and prevent asset loss.
It can collect equipment information in real time without manual intervention, automatically generate asset allocation, inventory and other operation records, flexibly and automatically output various query statistical reports according to selection conditions, and can be exported as an Excel table, thus avoiding the manual collection and entry of asset information. Due to a series of problems such as data distortion caused by human factors, the quality of basic data is guaranteed through automated management methods, and work efficiency is improved.
The system solution realizes the management of the entire life cycle of mobile assets from purchase, use, maintenance, scrapping and disposal. Through the comprehensive centralized monitoring and management of assets, it solves many management blind spots in the existing management mode, and aims to further improve The asset utilization rate provides data assurance.
The RFID system application only needs to write asset information in the back-end system and electronic tags at a time, and the system automatically records the change information of the asset, which turns the tedious manual recording in the daily asset management into “no manual recording required”, reducing information transmission Links to improve the accuracy and effectiveness of information.
Through intelligent dynamic real-time tracking and centralized monitoring and management of the entire life cycle of assets, it provides accurate reference for unit investment decisions and rational asset allocation, effectively increasing the marginal benefit of investment and improving asset utilization, reducing unnecessary equipment investment and idleness waste.
The asset management system based on RFID technology realizes the dynamic tracking management of “people, place, time, and things” in the real automatic information collection, which reduces the pressure of daily asset management and saves a lot of manpower and material resources every year for asset inventory and The cost of unnecessary allocation avoids the loss of assets caused by various factors and improves the efficiency of enterprise management.
Make full use of the characteristics of RFID technology and powerful background management system functions to show advanced management concepts such as “automatic management”, “asset management frontier” and “asset life cycle management”.
The whole 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. The implementation of this project does not require any changes to the existing equipment of the management site, and does not affect the normal operation of other businesses of the unit.
Make full use of RFID automatic collection to achieve real-time consistency between asset change information and system information, organically integrate daily work with IT systems, and achieve effective real-time monitoring and recording of work processes by the back-end system, so that managers can be in the office You can learn about the allocation and use of assets in time.
All asset data is entered at once, and the system automatically judges the asset status (new addition, allocation, idle, scrap, etc.) based on the data collected by RFID readers in different regions.
