1. Brief description of the system
In the competitive environment of economic globalization, management tasks such as improving production methods, increasing operating efficiency, reducing operating costs, and improving service quality have become the top priorities of major telecom operators. The fixed assets of communication enterprises have the characteristics of wide distribution, large quantity, high unit value and frequent adjustments. Under the current management mode, information distortion and lag caused by human factors in the transfer process of asset change information cause the account to be unable to be synchronized and consistent. The department was unable to optimize the deployment of equipment in a timely manner, resulting in a large number of high-value network assets being idle and wasting, which seriously affected the authenticity of financial reports.
As a bridge between the physical world and the existing IT system, RFID technology can effectively integrate daily asset management activities with the asset management system with the help of GPRS wireless remote transmission function, so as to achieve real-time synchronization of physical information and system information. Therefore, it has become possible to establish an asset management system based on RFID technology to realize automatic management.
2. System composition/design
(1) Reader: It integrates RFID reader module, GSM wireless communication module and reader power interface board to realize real-time automatic collection and wireless transmission of remote data. In the design of reader workflow, pass through the door The control switch controls the working state of the reader (the reader is in the reading state when the door is opened), thereby ensuring the service life of the reader and avoiding energy waste.
(2) Antenna: Due to the uncertainty of the direction of the electronic tag when the asset enters and exits the computer room, in order to ensure the effective identification of multiple angles, a circularly polarized antenna is used.
(3) Electronic tags: The communication industry assets have a wide variety of different specifications, and most of them are metal surfaces. Metal interference has always been a difficulty in the application of RFID technology. In order to solve the problems of metal interference and easy attachment to assets of various specifications, special Developed attached tags and tag tags suitable for assets of different sizes and specifications. Through the special design and packaging of the tag’s built-in antenna, the tag has good anti-metal interference performance.
(4) Card issuer: write data for the electronic tag, such as asset name, model, barcode number, etc., and can set a password, lock the data area, and prevent the data in the electronic tag from being rewritten.
(5) Handheld: Used for asset inventory, it can quickly read the electronic tag information on the device, and send the read tag information to the background server for processing through the built-in GPRS wireless communication module.
(6) Card issuing software: mainly used to write data into electronic labels, including device name, device model, device barcode, etc. After the data is written, reports can be automatically generated and imported into the GIS system server.
(7) GIS asset management auxiliary system and RFID middleware platform based on RFID technology.

4. System composition/features
(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) Establish safe and reliable registered asset files, strengthen asset supervision through high-tech, rationally allocate resources, reduce resource waste, and prevent asset loss. It can effectively and accurately identify, collect, record, and track the data information of the assets (equipped with electronic tags) entering and leaving the base station to ensure the rational use of assets.
(3) Fully consider the actual situation of the communication company, study the problem from the perspective of professional technology, and effectively solve the chaotic, disorderly and poor real-time problem in asset management. Provide an advanced, reliable, and applicable digital platform for automatic identification and intelligent management of incoming and outgoing assets, so that the ability of telecom operators to dynamically manage internal assets in real time is qualitatively improved.
(4) Make full use of the RFID automatic collection and GPRS wireless remote transmission functions to realize the real-time consistency of asset change information and system information, and use the alarm reminder function to organically integrate daily work with the IT system, and realize the back-end system Effective real-time monitoring and recording of the work process, so that managers can timely understand the allocation and use of assets in the office.
(5) All asset data are input at one time, and the system automatically judges the asset status (new addition, allocation, idle, scrap, etc.) based on the data collected by different base stations and regional RFID readers. The end user can use the visualized GIS operation interface at any time, Perform statistics and query of asset data through IE browser anywhere.
5. Implementation benefits
(1) Realization of “asset life cycle management” and “asset automatic management”: using RFID technology, radio frequency automatic identification and GSM communication network wireless remote transmission functions, to achieve the full life cycle of assets (new addition, allocation, idle, scrap , Maintenance, etc.) The process of intelligent dynamic real-time tracking and centralized monitoring and management, the entire management process does not require any manual intervention. It provides accurate reference data for enterprise investment decision-making and reasonable asset allocation, effectively increases the marginal benefit of investment and increases the utilization rate of assets, and reduces unnecessary equipment investment and idle waste.
(2) Realize the “simultaneous management of people, place, time and things” in asset management: The system organically embeds the daily asset management work into the asset management system, and realizes the tasks, locations, objects, and objects involved in the daily operation process of assets. Time and other information are recorded, and a reminder and alarm function is introduced. The system realizes effective supervision of daily work, reduces the pressure on daily asset management, saves the cost of investing a large amount of manpower and material resources for asset inventory and unnecessary allocation every year, and avoids various factors. The loss of assets caused by various factors has improved the efficiency of enterprise management.
(3) Realizing the paperless/addressing of asset management: The system adopts the public IP access address, and users can access the system through IE browser anytime and anywhere.
(4) The successful implementation of this project will become a model for the application of domestic RFID technology in the field of asset management, and will promote the large-scale application and development of RFID technology in other fields, thereby enhancing the social influence of the company. The implementation and application of the system completely eliminated the workload and error rate of manual recording and information transmission, achieved the expected application effect, and was unanimously affirmed by the maintenance personnel of the communication equipment.
