1. Introduction to the system
The rapid development of the communications industry and the rapid development of communications technology, as well as the formation of an economic globalized competitive environment, make improving production methods, increasing operating efficiency, reducing operating costs, and improving service quality management tasks that are currently the focus of major telecom operators’ work Heavy. 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, the information distortion and lag caused by human factors in the transmission of asset change information cause the account to be unable to synchronize, and the network 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
(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. 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 writing the data, it can automatically generate reports and import them into the GIS system server.
(7) GIS asset management auxiliary system and RFID middleware platform based on RFID technology.
Three, work flow
Asset management includes operations such as the addition, allocation, idleness, scrapping, maintenance, and inventory of assets. It includes the entire process of equipment from leaving the factory, putting into use, and scrapping. The equipment is equipped with electronic tags when leaving the factory, and the asset information is written in the tags. Every time an asset management operation is performed, the reader will read the electronic tags on the assets and send the information to the server for processing, thereby realizing asset tracking management .
(1) Asset addition operation: fill in the relevant information (site name, asset barcode, model, name) of the equipment to be managed in the card issuance program, and save the record in the database. Attach electronic tags with asset information (or hang on assets) as required.
(2) Asset transfer operation: prepare the assets to be transferred, open the door that controls the travel switch, and the reader is in the state of reading tags at this time. Take out the asset with the electronic label, walk out from the door, observe the sound and light prompt on the reader and the LED display to show the number of assets, and confirm that the electronic label on the device is read. After closing the door, the assets have been transferred from the base station. Bring the asset to the destination that needs to be allocated, open the door, bring the asset into the base station, and confirm that the electronic tag on the asset is correctly read. Close the door and complete the asset allocation operation.
(3) Asset maintenance operation: prepare the equipment that has failed, and open the door that controls the travel switch, so that the reader is in the state of reading tags. Take out the faulty device, observe the digital tube display on the reader, and confirm that the label is read correctly. Close the door of the base station, and the faulty device will be transferred away from the base station. Take the equipment to the warehouse maintenance area, press the reader control button (the indicator light on the button is on), confirm that the label information on all equipment is correctly read, press the reader control button again (the indicator light on the button) Off), the device is now under maintenance.
(4) Asset scrapping operation: prepare the scrapped equipment, open the door that controls the travel switch, so that the reader is in the state of reading tags. Take out the end-of-life equipment and confirm that the label is read correctly. Close the door of the base station, and the scrapped equipment will be removed from the base station. Take the equipment to the scrap area of the warehouse, press the control button of the reader in the scrap area, and confirm that the label information on the equipment has been read correctly. Press the reader control button again to complete the equipment scrapping operation.
(5) Asset inventory operation: press the “I/O” switch of the handheld to turn on. At the top of the interface, click to open the connectivity window, and click to connect to GPRS. Start the inventory process.
Four, system advantages
(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 assets (assets with electronic tags) entering and leaving the base station (library) 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.
