1. RFID Electronic Tag Concept and Application Prospects 1.1 Concept RFID (Radio Frequency Identification) electronic tags are not a new technology. This technology actually emerged in the 1980s and has been used in specific fields, such as automated production lines in factories, warehouse inventory management, and station ticket checking. However, with the increasing maturity of this technology, its smaller size, lower cost, and suitability as an information carrier, it has become increasingly suitable. RFID is an abbreviation for Radio Frequency Identification, a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data from them through radio frequency signals. 1.2 Prospects Power grid restoration after snowstorms is extremely difficult, especially in Jiangxi and Zhejiang provinces. This difficulty stems from the fact that, in the early stages of power grid construction, to save energy, some towers on the main power grid in Jiangxi and Zhejiang were located in mountainous areas. These mountainous areas have low temperatures and strong winds, making tower collapses most severe. Furthermore, due to local geographical and natural limitations, accurate information about damaged power towers cannot be obtained. Therefore, it is difficult to develop timely post-disaster repair plans, delaying repair efforts. Power monitoring systems using RFID electronic tag identification technology can help solve this substantial problem. RFID tags are attached to power poles. From the day the pole is built until it is scrapped, the RFID tag acts like an ID card, recording all its information, including its serial number, construction date, daily maintenance, repair process and frequency. It can also record the pole's geographical location and latitude/longitude coordinates to construct a GPS-based power grid distribution map. Helicopters equipped with RFID terminal interrogation readers can read the pole's condition information from the air to determine if it is damaged, rusted, and its detailed address. The terminal antenna is mounted on the helicopter's belly and extends downwards. 2. Feasibility Analysis 2.I RFID Working Principle RFID electronic tags are divided into passive tags and active tags. Active tags are powered by their own batteries, have a longer read/write distance, but are larger and more expensive than passive tags; they are also called active tags. Passive tags obtain the energy needed for operation from the magnetic field generated by the reader, are low-cost, have a long lifespan, are smaller and lighter than active tags, and have a shorter read/write distance; they are also called passive tags. Active tags, due to their advantage of long-distance identification, are mainly used for the identification of large, high-speed moving objects. The power poles mentioned here use active UHF ultra-high frequency RFID tags, with a frequency band between 860MHz and 960MHz, to ensure that helicopters can maintain normal communication with RFID tags from 50m away in the air. 2.2 Composition of RFID electronic tag identification system A real RFID electronic tag identification system should at least include electronic tags, readers, data processing and storage equipment, and system software. (1) RFID electronic tag (Tag): Each tag has a unique electronic item code and is attached to an object to identify the target object; (2) Reader (Raeder): A device that reads (and sometimes writes) tag information; (3) Antenna (Antenan): Transmits radio frequency signals between the tag and the reader. It provides power to the passive electronic tag on the one hand, and receives information emitted by the electronic tag on the other hand. It can also transmit written information to the electronic tag. In addition, each electronic tag also has its own micro antenna. RFID electronic tags consist of an antenna and a dedicated chip. The antenna is a copper film coil plated on a plastic substrate. Embedded in the plastic substrate is a very small integrated circuit chip (currently only the size of a sesame seed, and even smaller). This integrated circuit chip comprises a high-speed radio frequency interface, a control unit, and an EEPROM module. Compared to barcode technology, RFID electronic tag technology has the following advantages: 1) No light source required; data can even be read through external materials; 2) Long lifespan, capable of operating in harsh environments; 3) Longer reading distance; 4) Can write and retrieve data, with fast writing time; 5) Tag content can be dynamically changed; 6) Can process multiple tags simultaneously; 7) Tag data access is password protected, providing higher security; 8) Can track and locate objects to which RFID tags are attached. The reader mainly includes a radio transceiver antenna, data communication, and corresponding control circuitry. The electronic tag mainly includes circuitry for receiving and transmitting radio waves, a power supply, and circuitry for storing data. Data processing and storage devices are often PCs, which typically have corresponding system software and database management software installed. 3. Construction of Power Facility Monitoring System 3.1 Practical Application of RFID Electronic Tags in the System When power poles are first built, some fixed attributes are pre-written into the tags, such as construction time and pole number. Simultaneously, GPS positioning devices can be used to record the pole's latitude and longitude information, which is also written into the tags as fixed attributes. After each pole maintenance, staff carry a handheld reader (usually a handheld computer with an embedded reader module, its basic principle is the same as a dedicated reader) to write relevant maintenance information into the tags, including the pole's latitude and longitude location, current status, and existing problems. The distribution of power poles is viewed using a GPS-based power grid distribution map to quickly determine the geographical location of problematic poles, providing effective repair solutions for emergency repair personnel. 3.2 Relevant Processes Regularly dispatch helicopters to inspect power poles, especially after major disasters such as snowstorms when land conditions are extremely poor. Aerial monitoring is essential. The aircraft's reader identifies the power poles, and after obtaining specific information, returns to the computer. The reader connects to the computer, and the retrieved tag information is transmitted to the computer management center for further processing. To make the information more intuitive, a GPS-based power grid distribution map can be established on the management platform, integrating map visuals, power facility geographic information, and database operations. After the latitude and longitude information of the electronic tags is entered into the computer, the specific geographical location of the poles can be directly displayed on the distribution map through database searches, forming a complete monitoring system in conjunction with real-world photos. 4. Issues to be Addressed 4.1 Lack of Standardization in RFID Electronic Tags Currently, there are two authoritative international RFID electronic tag standard research institutions, representing the development direction of RFID electronic tag standards. One is AutoIDCenter, established in 1999 and headquartered at MIT in the United States; the other is UbiquitousIDCenter, established in Japan in March 2003. The standardized specifications offered by these two centers differ somewhat. For example, the AutoIDCenter specification uses 96-bit codes to describe the data contained in the IC tag, while the UbiquitousIDCenter uses 128-bit codes. The AutoIDCenter explores the IC tag mechanism based on the premise of utilizing the Internet, while the UbiquitousIDCenter considers using IC tags without an Internet connection. Both centers have now completed their respective infrastructure development. AutoIDCenter proposes an architecture consisting of a 96-bit ID called ePC, a PML server that manages ID information, and an ONS (Object Name Server) server that retrieves the location of the PML server. UbiquitousIDCenter will apply T-engine technology, including 128-bit IDs and a proprietary protocol called E-Operation (Entity Transfer Protocol). This also includes Address Resolution Servers (ARS) used to search for IC tags and server locations. The lack of standardized protocols is a significant factor hindering the widespread adoption of RFID. 4.2 In practice, the metal parts of helicopters, power poles, and cables can interfere with the antennas of tags and readers, even blocking signals, directly affecting normal communication between the reader and the tag. Furthermore, a high error rate is another area where RFID technology needs improvement. These all require further refinement of the solution, but with the increasing prevalence of RFID electronic tags, RFID technology will gradually solve these problems—an inevitable path for any new technology. 5. Conclusion In future power monitoring systems, the superior characteristics and intelligent management of RFID electronic tags will help people obtain various relevant information more promptly and accurately. Once power facilities are damaged, it will guide the correct repair plan, saving valuable repair time. This will enhance the entire power grid's ability to cope with various natural disasters, making the power grid more robust. Editor: He Shiping
