In recent years, with the rapid development of smart grids, both domestic and foreign companies have attached great importance to information security protection in the construction of smart grids, and countries have invested a lot of manpower and material resources in this regard, but due to the special requirements of the smart grid environment and RFID With the characteristics of technology, the research and application of high-security RFID technology for smart grids are in the initial stage.
The smart grid high security RFID has a unique global identity and cannot be tampered with and copied. At the same time, the data is encrypted and stored to ensure the confidentiality and integrity of the data, and the security and reliability of the smart grid data can be improved. Smart grid high security RFID integration SMK security algorithm, RFID RFID tag authentication process uses 3 data transmission authentication methods, through two-way authentication, data transmission is more secure, stable and reliable.
The smart grid high security RFID technology has the advantages of waterproof, high temperature resistance, long service life, large read distance, data encryption, large data storage capacity (512bits of user storage space), and easy read and write of storage information that are not available in barcodes and two-dimensional codes. advantage. Smart grid high-security RFID technology is used for smart grid equipment asset management, which can improve the automation level of equipment assets and ensure the security of equipment account information.
The integration of smart grid high security RFID and current transformers has been widely used in many provincial companies and transformer manufacturers. It has realized the injection and export of transformers from manufacturers, warehouses of various provinces, warehouses, inspections, distribution, installation, and inspections. The whole life cycle management, such as inspection and scrapping, has greatly saved the workload in the aspects of storage, inspection and verification, reduced the production cost, effectively solved the problem that the nameplate of the current transformer was maliciously tampered with, and prevented the transformer from appearing after installation. The electricity stealing phenomenon has achieved remarkable social and economic benefits.
Application target
(1) To realize the management of the entire life cycle of the smart grid equipment, reduce the workload of equipment access, inspection, and inspection, and improve the automation level of equipment management.
(2) Ensure the uniqueness of the identification of smart grid devices at the entrance, exit, delivery, inspection and other links.
(3) Improve the safety and reliability of smart grid data.
Precautions
(1) The integration of the chip and grid equipment does not affect the normal and safe operation of the equipment.
(2) When integrating injection molding with power grid equipment, pay attention to whether injection molding materials will interfere with UHF RFID RF signals.
(3) There are many devices in the smart grid system, and it is necessary to study the classification of smart grid high-security RFID technology, improve the automation level of smart grid equipment management, and improve the safety and reliability of smart grid data.
As the demand to control diesel engine emission increase, the in-cylinder optimisation technology is not satisfied with the standard request; In order to achieve the standard IV or higher standard level, it need to use SCR technology, SCR is mainly technology to reduce the emission of diesel engine emission.
