Since the rise of the Internet of things, from small retail industry to large aviation industry, from animal husbandry management to food transportation, all walks of life have begun to move closer to the Internet of things. From traditional manual operation to mechanized management, and then to today's automatic management and intelligent production, systematic management is constantly optimized and improved, so that its work efficiency is also continuously improved. Under this promotion, RFID technology has been rapidly developed and widely used.


In recent years, many regions in China have begun to pilot RFID tag cable management in a small area. According to the data, Guyuan power supply company of State Grid has various asset types, large scale and scattered locations. In the process of physical asset management, it is faced with problems such as long management chain, long equipment cycle life, frequent physical changes and value changes. In the past, the acceptance of power grid equipment required the equipment account management personnel to copy or take photos one by one, and then enter them into the information system. The work was cumbersome and large,affecting the accuracy.


The construction and application of "physical ID" makes the management and maintenance of power grid asset account information more convenient and the accuracy of account information higher.

In August 2018, the construction of "physical ID" of State Grid Guyuan power supply company was in full swing. According to people's information, Wuyi County power supply company of State Grid, as a pilot unit of cable electronic tag (RFID) technology of Jinhua power supply company of State Grid, adopts RFID tag management. Technicians shall install high safety and low frequency electronic markers, tie type UHF labels and adhesive UHF labels for cable wells, cables and switching posts respectively. The route and well are defined through the cable path detection instrument, and the PDA is used to collect and store the RFID tag data, so as to finally form a complete set of cable pipeline geographic data map, and mark the location coordinates of each cable well, the direction of all cables and the position of intermediate joints on the geographic map, so that the complete well information can be viewed in each cable well. At present, the construction of "physical ID" of each power grid equipment in 62 substations under the jurisdiction of State Grid Guyuan power supply company has been completed. By scanning the RFID electronic tag on the equipment, the management personnel can know the source, installation process, commissioning and maintenance information of the equipment, as well as the operation instructions and dangerous points of key equipment at a glance.

 

The working principle of Hadesheng RFID tag compounding machine is to bond the antenna and inlay first, and then conduct compound die-cutting between the blank tag and the bonded inlay through the die-cutting station. If it needs to be made into self-adhesive type, it needs to add adhesive and backing paper. If it is made into tag type, it can directly process the tag data (RFID tag code writing and inkjet detection machine can be used to adddata), The finished RFID tag can be directly applied in the terminal.



The high-speed compound machine of Hadesheng RFID tag adopts dry and wet inlay transfer, and the jump distance of dry inlay cutting is 12mm; Four independent inlay, four layer nested compound; Self adhesive paper separation and recombination; Three die cutting, upper / lower knife. Performance advantages: the maximum running speed can reach 100M / min, and the quantity of pieces completed every eight hours is 40W; Stable production accuracy < ± 0.5mm, outer frame cutting accuracy < ± 0.2mm; Inlay scrap removal and labeling, visual inspection, finished product defect detection + identification function.


According to people's information, Wuyi County power supply company of State Grid will further promote the management of cable digital operation and maintenance, make full use of RFID tags to realize cable digital census, deeply mine data value, strengthen digital empowerment, improve emergency repair efficiency, improve power supply reliability, reduce equipment operation and maintenance costs and increase social and economic benefits in combination with power supply service command system and distribution automation master station system.


The application of cable electronic tag (RFID) technology lays a solid and comprehensive data foundation for the construction of smart grid. At the same time, it marks the transformation of cable pipeline operation and maintenance from extensive to digital management of Wuyi County power supply company of State Grid. The application of the project has greatly promoted the whole process control of cable channel design, construction, acceptance, operation, maintenance, emergency repair and completion data maintenance, standardized and realized the purpose of digital and process management, so as to further improve the operation and management level of power grid.
