Electricity is one of the pillar industries of national economy, a province of the company's total assets is usually tens or even hundreds of billions of dollars, and 99% of them belong to production operational assets is a very typical flow type industry, all of its production and operating activities all around the normal operation of the assets Therefore, the importance of enterprise asset management is to the electric power industry is far greater than other discrete manufacturing enterprises Asset management in electric power industry, for example, is an indispensable important component in the ERP, for discrete manufacturing industry,so is not necessarily .
In energy prices are high, the increasingly fierce competition in the market today, the economic benefits of power enterprises face increasing pressure How to more effectively reduce costs, from the enterprise internal market competitiveness, improve the assets into productivity is more important Asset management as a result, the power industry has long is no longer just stay on the track of inventory assets management level, but to fully from the build to the daily maintenance, to scrap the whole life process assets running normally for real for the power industry is lifeline, and how to ensure that assets under the premise of running state, reduce the cost of repair and maintenance of assets is the electric power enterprise excavate internal potential to improve the economic benefit are unavoidable problems.
Entering the 21st century, the role of information system for enterprise management should be no doubt After decades of enterprise informatization practice, lots and lots of experience and lessons, enterprise informatization not only includes the software of computer and network, the lack of high quality of field data, more powerful and perfect information system is also difficult to play its proper role, the humiliation of a hero and a useless Therefore, the importance of data mining technology in the enterprise information, with more and more attention, as well as for enterprise asset management system.
The second chapter, the RFID technology is introduced
2.1 summary of RFID
RFID technology as an extension of the smart card application technology in the intelligent enterprise management mode has an irreplaceable role Electronic label (Tag) is also called radio frequency sensors, generally with the antenna, memory and control system of low power integrated circuits, it can store need to identify the transmission of information, is to identify personnel and items, to facilitate identification tool track and record the RFID radio frequency identification technology can in under the action of external force, the information will be stored Electronic tags with smart card big amount of information Easy to identify information cannot fake characteristics; Also has the non-contact, speaking, reading and writing data read and write speed Provide multiple encryption information storage is more security features; And information storage format relative IC card and magnetic stripe card is more simple Electronic tags good physical properties for use in a variety of goods of any shape is possible Because the electronic label has the advantage, therefore, as a information storage carrier can have identity recognition Merchandise anti-counterfeiting goods management, and so on.
2.2 working principle of the RFID
The working principle of RFID technology is: reader reading data from the receiving radio waves from the label system with active and passive radio frequency system Is one of the most common passive radio frequency system, the reader will be encrypted data carrier signal by the transmitting antenna to send, in its surrounding electromagnetic field; Electronic tags into the transmitting antenna working area after the energy from the electromagnetic field in the activation of label in microchip circuit, the chip will electromagnetic transformation, and then sent to reader, reader converts it into the relevant data control calculator can deal with these data to management control In active rf system, equipped with battery electronic tag can only be effective within the scope of activities.
2.3 the working frequency of RFID and application scope
Radio frequency identification system is main working frequency of 125 KHZ to 13.56 MHz, 433 MHz, 860 ~ 960 MHz 2.45 GHz, maximum allowable emission power level and frequency distribution is different for different countries and regions 125 KHZ system is mainly used in animal identification and circulation of commodities, etc. 13.56 MHz system commonly used in the field of public transport and entrance guard system, its identification distance, typically a few centimeters to a few centimeters, made of special antenna maximum recognition distance is about 1.5 m In the UHF frequency band, the system identification distance, can from several meters to tens of meters 433 MHZ band is mainly used in the container tracking management; 860 ~ 960 MHZ band is mainly used in the logistics warehouse management of supply chain security management and other business assets of passive system (passive tag) 2.45 GHz system generally can provide a few meters identification distance, active system (active) can also achieve recognition distance of tens of meters.
2.4 the RFID technology characteristics and advantages
1) convenient read
2) Faster recognition
3) large capacity of data
4) Long service life, wide application range
5) The tag data dynamically changes
6) Superior security
7) The dynamic real-time communication
The third chapter :asset management application requirements and solutions of the electric power industry
3.1 requirements overview
In electric power equipment asset management, the need to adopt the application of automatic identification technology mainly include: whole life cycle of fixed asset management, asset tracking and equipment inspection and maintenance Among them: the introduction of RFID radio frequency in the fixed assets management system, using handheld terminals, it is best to support the handheld terminals, wireless data communication not only can greatly improve the work efficiency, save labor costs, more can avoid artificial inventory cannot be avoided in all kinds of mistakes, make enterprise more accurately grasp the stock and distribution of fixed assets This point in the state pay more and more attention to the state-owned assets supervision, as well as the enterprise capital operation is more and more frequent today is especially important.
3.2. Fixed assets management
Fixed assets management system according to different process is divided into several subsystem: assets daily management Fixed assets inventory assets in and out of the assets under management maintenance management Depreciation report management.
3.3 Equipment inspection and maintenance
Equipment inspection and maintenance belong to the state of the equipment maintenance management, inventory and fixed assets and asset tracking and managing the whole life cycle of different, but due to the change of the state assets involved, and is closely related to the whole life cycle of tracking equipment inspection and maintenance to check the equipment running status, discover hidden dangers ahead in time, to avoid the hidden trouble to develop into failure leads to a greater loss Inspection personnel, after the discovery of the equipment hidden trouble need to report timely accurate and clear, complete the relevant situation, relevant departments will be arranged according to the report provided by the information maintenance personnel to repair, eliminate the hidden trouble.
