RFID power asset management systems for the fixed assets management of State power and the development of suitable assets inventory, tracking, checking and maintenance of information systems. The system is based on the Internet of things RFID technology, takes full advantage of RFID technologies wireless remote recognition, batch identification, specification data, suitable for indoor and outdoor complex environment as well as for power assets information management to provide technical support.
Chapter one background
With the advent of 21st century digital information age, people have attached great importance to the use of network environment information exchange and information management and digital technology; intelligent management model has become an important component of development. Many successful enterprises by applying digital technology to help improve the operation and management mode of enterprises, improve the economic efficiency of enterprises so that enterprises occupy a more favourable position in the competition.
Electricity is one of the pillar industries of the national economy, but also a very typical asset-intensive industries, total company assets, usually a province, there are tens of billions of billions of Yuan, and 99% belong to the production and operation of the assets. Power is also very typical process industry, all of its production and business activities are centred on the normal operation of the assets. Therefore, enterprise asset management for power industry's importance is much larger than the other discrete manufacturing enterprises. For example, ERP for asset management in the electric power industry is a necessary and important part of discrete manufacturing industries, is not necessarily the case.
High energy prices and increasingly fierce competition in the market today, power enterprises are facing increased economic pressures. How to more effectively reduce costs from internal market competitive power of enterprises
Chapter II introduction to RFID technology
2.1 Overview of RFID
RFID technology as an extension of smart card technology, Enterprise intelligent management pattern plays an irreplaceable role. RFID tag (Tag) also known as RF sensors, with antennas, memory and control system of low power integrated circuits, it can store need to identify the transmission of information, is to identify people and goods, to facilitate the identification, tracking and recording tool. RFID radio frequency identification technology in the presence of external forces, will store the information out. RFID smart card information storage, easy identification, characteristics such as information could not be counterfeited; also have non-contact reading and writing, reading and writing data fast information storage, provides multiple encryption security features and information store format IC card and magnetic strip card simpler. Tags good physical properties for use in a variety of products of arbitrary shape possible. Because the tag has the above advantages, therefore, as an information carrier to identify recognition, commodity security, management, and so on.
2.2 RFID works
RFID technology works is: reader reads data received through the receive radio tags. Radio frequency system with active and passive systems. Is the most common passive RFID system, reader will encrypt the data carrier signal by transmitting antenna sends out in its surrounding electromagnetic electronic tags after entering the antenna work area obtained from the electromagnetic energy to a micro-chip in the label circuit, chip will convert electromagnetic waves, and then sent to the reader, reader turn it into relevant data. Control calculator can process this data to management control. Active RF system, with a battery of electronic label only in effective, their activities.
2.3 RFID frequency and scope of application
RFID system operating frequency there are 125KHz, 13.56MHz, 433MHz, 860~960MHz, 2.45GHz, the maximum allowable transmitter power level and frequency allocation for countries and regions differ. 125KHz system is mainly used in the field of animal identification and circulation of commodities, such as. 13.56MHz system for general applications in areas such as public transport and access control system, its distance, usually a few centimeters to dozens of centimeters, using a special produced by the antenna maximum identification distance of about 1.5 meters. In the UHF band, the recognition distance from several meters to dozens of meters. 433MHz is mainly used in container tracing management; 860~960MHz bands are mainly used in logistics and supply chain, warehousing management, asset and safety management in the business. 2.45GHz systems passive systems (passive tag) provides the recognition distance of a few meters, active system (active tag) can also achieve the recognition distance of dozens of meters.
2.4 characteristics of RFID technology and advantages
1) reads fast and easy
2) recognition speed
3) large volumes of data
4) long life and wide range of application
5) label data can be dynamically changed
6) better security
7) real time communications
Chapter III electric power industry asset management applications and solutions
3.1 requirements overview
In asset management of electric power equipment, automatic identification technology application is needed include: full life-cycle asset management, asset tracking and equipment inspection and maintenance. Where: introduced in fixed asset management, RFID radio frequency systems, handheld terminals, handheld terminal that best supports wireless data communication, can not only greatly improve working efficiency, to save labor costs, also cannot avoid the anomalies in the manual count, make enterprises more accurately fixed asset inventory and distribution. This country more and more attention to supervision of State-owned assets, and capital operation of enterprises today, more and more frequently is especially important.
3.2. fixed asset management
Fixed assets management system based on different process is divided into several subsystems:
Fixed assets inventory
Management of assets in and out
Asset maintenance management
3.3 asset life cycle management
3.4 equipment inspection and maintenance
Equipment inspection and maintenance of equipment maintenance and management, fixed asset inventory and asset life-cycle management is different, but due to changes in asset condition, and is closely related to life cycle tracking. Equipment inspection and maintenance to check the running status of equipment, discover hidden dangers in advance in order to avoid risks to develop into failure leads to greater losses. Inspection following the discovery of hidden trouble of equipment needs to be timely, accurate, clear, and complete reports, relevant departments will, according to the report provided information on organizational arrangements for maintenance personnel to repair, eliminate the vulnerability.
