If the grid detection work is not in place, can not grasp the specific information related to power facilities in a timely manner, which for the power grid-related departments management, repair and recovery of the work is a very big impact. Therefore, it is necessary to establish a perfect power monitoring system.
How to use RFID tag to monitor power facilities?
RFID tags This technology actually emerged in the 1980s and has been used in specific areas, such as factory automation lines, warehouse goods management, or station ticketing. But this technology is becoming more and more mature, in smaller and smaller forms, at lower and lower costs, and increasingly suitable as an information carrier.
For example, it is difficult to restore the power grid after a snowstorm, so it is difficult because at the beginning of the construction of the power grid, in order to save drug costs, and did not use RFID or related technologies, resulting in problems after the inability to accurately grasp the relevant information about the damaged towers. Therefore, the post-disaster repair plan cannot be proposed in time, which delays the repair time. The power monitoring system using RFID tag identification technology can help solve this substantial problem.
RFID tags are attached to the power tower. From the first day of tower construction to scrapping, RFID tags record all its information like an ID card, including number, completion time, daily maintenance, repair process and times. In addition, they can also record the tower’s relevant geographical location and latitude and longitude coordinates, so as to build a GPS-based power network distribution map. The helicopter with RFID terminal interrogation RFID reader can read the status information of the tower from the air, and determine whether the tower is damaged, rusted, and its detailed address. The terminal rfid reader antenna is installed in the belly of the helicopter, leading downward.
RFID electronic tag technology compared to bar code (Bacrde) technology has the following advantages.
- No light source is required, and data can even be read through external materials.
- long service life and the ability to work in harsh environments.
- readable over greater distances.
- writable, accessible data and fast write times.
- the content of the tag can be dynamically changed
- multiple tags can be handled simultaneously.
- tag data access is password protected for higher security
- Objects attached to the RFID tag can be tracked and located.
The RFID TAG reader mainly includes radio transceiver antenna, data communication and the corresponding control circuit. Electronic RFID tags mainly include radio wave receiving and transmitting circuits, power supply and data storage circuits. The equipment that performs data processing and storage is often a PC, which is generally installed with the corresponding system software and database management software.
After understanding some of the functions of RFID tags, let’s talk about the practice
RFID tags in the system of practical applications.
When the tower is built, some fixed attributes of the tower are written into the RFID tag in advance, such as the completion time, the number of towers, etc. At the same time, GPS positioning equipment can be used to record the latitude and longitude information of the tower, which can also be written into the RFID tag as a fixed attribute. After each maintenance of the tower, the staff carries a handheld reader (usually a handheld computer with embedded RFID read-write module, the composition principle is basically the same as the reader) to write the relevant maintenance information into the RFID tag, including the location of the tower’s latitude and longitude, the current situation, the existence of problems and other information. According to the GPS-based grid distribution map to view the distribution of towers, quickly determine the geographic location of the problem tower. Provide effective repair solutions for emergency repairers. Arrange helicopter patrol of towers on time. Especially in the case of very poor land conditions after major disasters such as snowstorms, aerial monitoring is an unavoidable measure. The reader on the aircraft identifies the tower. After obtaining the specific information of the pole tower, returns the common reader to connect with the computer, transmits the read tag information to the computer management center for further processing. In order to make the information more intuitive, we can establish the GPS-based electric power network distribution map on the management platform, integrating map visual effect, geographical information of electric power facilities and database operation. After entering the latitude and longitude information in the electronic tag into the computer, the specific geographic location of the tower is directly displayed on the distribution map through database search, and a complete monitoring system is realized with the help of on-site photos.
So what problems do we need to deal with when using rfid tags and related systems?
1, RFID tags are not uniform standards. Electronic tags are divided into high frequency, UHF and other frequency bands, there are passive and active; 2. Communication. In fact, the metal parts of the helicopter, power towers and cables will interfere with the antenna of the tag and reader to some extent, and even shield the signal, directly affecting the normal communication between the reader and the tag. In addition, the high bit error rate is also an area where RFID technology needs to be improved. These need to be further improved, but with the growing popularity of RFID tags, RFID technology will gradually solve these problems, which is the way to any new technology.
In the future electric power monitoring system, RFID electronic label’s excellent characteristics and intelligent management will help people more timely and more prepared to grasp all kinds of related information. Once the electric power facility is damaged, it will guide the correct maintenance plan and save the valuable maintenance time. Thus, the whole power grid will improve the ability to cope with various natural disasters and make the power grid stronger.
