RFID technology helps smart grid asset management
In recent years, my country has included the Internet of Things and smart grid networks as a national key project. The introduction of Internet of Things technology into smart grids can not only effectively integrate resources and infrastructure in all aspects of power production, transmission, distribution and consumption, and improve The informationization, intelligence and integration of the power system have greatly improved the utilization rate of the power infrastructure.
The Internet of Things includes three levels: perception layer, network layer, and application layer. A smart grid designed based on the composition of the Internet of Things consists of a perception layer, an analysis layer, a data layer and an application layer.
1. Perception layer: Data collection and perception are mainly used to collect data on power supplies and equipment. In the power Internet of Things, the State Grid Corporation of China identifies information resources such as power supplies, equipment, and assets into an RFID electronic tag. Such as material classification code, equipment classification code, functional location code, etc.
2. Analysis layer: Through the RFID handheld terminal, the information of the perception layer can be analyzed and transmitted without barriers, high reliability and high security.
3. Application layer: It mainly includes application support platform sublayer and application service sublayer. Among them, the supporting platform is mainly an ERP platform. Application services mainly include power material procurement management, equipment inspection and repair management, fixed asset management, and asset life cycle management based on this.
4. Data layer: To be precise, the data layer does not belong to a specific layer of the Internet of Things technology, but uses PDA security technology to analyze data to the data center.
The system structure diagram of the smart grid designed based on the above architecture, in which the power equipment, inspectors and the electronic tags covered on it belong to the perception layer, the PDA handheld computing device belongs to the analysis layer, and the client PC and server correspond to the application layer of the system And data layer. The Internet of Things for smart grid applications should mainly include a perception layer, a network layer, and an application service layer. The perception layer mainly uses wireless sensor networks, RFID and other technical means to realize the collection of relevant information of each application link of the smart grid; the network layer is mainly based on the power optical fiber network, supplemented by the power line carrier communication network and wireless broadband network, to achieve various types of perception layers Information transmission in a wide area or a partial range of power system information; the application service layer mainly adopts intelligent computing, pattern recognition and other technologies to realize the comprehensive analysis and processing of power grid information, realize intelligent decision-making, control and service, thereby improving various applications of the power grid The level of intelligence of the link.
What are the applications of RFID technology in smart grids?
Power Asset Management
Traditional electricity meter management generally uses barcodes, but it was later confirmed that the barcode information cannot be changed and the capacity is small. The barcode labels are easy to fall off and damage, which easily affects the normal reading of the equipment. Therefore, the power company uses RFID instead of barcodes to achieve effective metering. management. Attach RFID electronic tags to the electric meters, and then collect the data information of the electric meters through the corresponding RFID equipment, and manage the fast in and out of the electric meters through the RFID channel machine, which realizes the batch identification of the RFID tags of multiple boxes of electric energy metering equipment.
Electrical equipment management
Whether it is installing access doors at the entrance of a small warehouse or using other methods such as platform installation to manage warehouse tools, when workers use readers to read tool tags, there will inevitably be cross-reading and omissions to make it unclear which ones are taken away. The question of what tool. Using RFID technology, put tools with RFID electronic tags in a specially customized smart tool cabinet equipped with RFID readers. Whenever the tool is taken out of the cabinet, the system will record this operation in real time. It will immediately determine the details such as: who, the main responsible position, when what tools were taken out, and when to return them. The system can also set operating permissions, and can automatically issue a warning when a tool is not returned within a certain period of time.
Operation process: The fully enclosed cabinet provides a keyless access method, and the storage of tools is very simple → After the employee swipes the employee card and touch screen login is completed, the cabinet system is turned on, and the employee is authorized to access the tools → click the desired tool on the touch screen , The electromagnetic lock of the corresponding tool storage drawer will be automatically opened, the software will automatically record each access operation in real time, and automatically update the database → Once the access operation is completed, when the drawer is closed, the touch screen will immediately display the update status of the item.
Power file management
Generally, file management based on RFID technology consists of a system and terminal management equipment. Its terminal management includes RFID electronic tags, Honlu UHF channel access control, UHF handheld terminals, Honlu RFID reading and writing equipment and card issuers, etc., which are systems to obtain information Important port with output information. The entire system realizes the informatization management of the file management process through the close cooperation of all links. Among them, the Honglu UHF handheld terminal plays a pivotal role in the deployment of the entire RFID system, which can quickly realize file storage, borrowing, returning and querying.
Power inspection management
Power equipment inspection is a basic task to effectively ensure the safety of power equipment, improve the reliability of power equipment, and ensure the minimum failure rate of power equipment. Through the RFID handheld terminal, paperless data collection can be realized, and at the same time, the equipment and power equipment management department can effectively supervise the work of the inspection personnel, and realize the electronic, information and intelligent inspection work, thereby maximizing the work Efficiency ensures the safe operation of power equipment and power equipment with a low failure rate.
Compared with traditional power grids, smart grids can achieve intelligence based on the complete mastery of power grid information, based on the premise that RFID read-write devices collect data, and ensure data security, stability and reliability during data transmission and conversion. The smart grid realizes the management of the entire life cycle of equipment, reduces the workload of equipment storage and inspection, and improves the automation level of equipment management.
