The application of RFID technology in the inspection of substation equipment

RFID is the abbreviation of radio frequency identification, that is, radio frequency identification. Commonly known as electronic labels. RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not need human intervention. It can work in various harsh environments. RFID technology can identify high-speed moving objects and multiple tags at the same time, which is fast and convenient to operate. Through the RFID automatic inspection system, the security inspection ability of the power industry is greatly improved, and this work has reached a new level. Using RFID technology to inspect substation equipment mainly has the following advantages

first, resist external forces and quickly collect data

we know that transmission and distribution lines and equipment are important components of the power system. They are mostly in long-term operation. They are exposed to nature for a long time. They not only bear the role of normal mechanical load and power load, but also suffer external forces such as pollution, lightning strike, strong wind, flood, landslide, subsidence, earthquake and bird damage. The above factors will promote the aging, fatigue, oxidation and corrosion of components on the line. If they are not found and eliminated in time, they may develop into various faults at present, posing a great threat to the safety and stability of the power system. When carrying out power inspection based on bar code technology, bar code labels that are outside all year round are often unable to be read after assembly and service life due to wear or dirt on the outside of the label, because bar codes based on the characteristics of photoelectric technology have very high requirements for the integrity and cleanliness of label surface printing. The technical characteristics of RFID itself (strong ability to prevent pollution, damage, ultraviolet and other outdoor harsh environments, long reading distance, repeated deletion and writing of information, large storage capacity, anti-collision) have found the best solution to this problem. Radio frequency technology adopts the principle of radio technology. The reading equipment can quickly collect data through radio waves

second, control the arrival rate of safety personnel and standardize information input

the patrol inspection work is divided into two parts: substation patrol inspection and line patrol inspection. Among them, due to the need to cross mountains, the control work in place is particularly important. In order to control the arrival rate of inspectors. The method of "material object retrieval" has been used. That is, tie the marking strip on the equipment to be inspected in advance. The inspector shall take back the sign strip when the patrol inspection starts. To verify the inspection arrival rate. When controlling the inspection arrival rate based on barcode technology, although inspectors use barcode handheld inspection equipment to scan the barcode pasted on the equipment. The ID number information in the bar code is collected, but the bar code is easy to be copied and easy to be stained, which makes the arrival rate of power inspectors unable to be guaranteed. In addition, the substation patrol inspection requires inspectors to patrol the substation equipment regularly or irregularly, and simply record the operating conditions and operating parameters of the equipment. Using the RF reading and writing equipment system, it is easy to realize the work arrangement of inspection and the data collection of the effect of defect injection rate on the mechanical properties of micro injection molded blends. In the management of RF equipment, the information data is transmitted to the background system for analysis in real time through the on-site inspection and collection terminal, so as to realize the inspection in place control and the standardization of defect information input

III. patrol inspection in special environment to ensure the safe operation of power supply system

for some patrol inspection work in special environment, such as patrol inspection of equipment in high-voltage environment or equipment with a certain height, it is difficult to complete the patrol inspection work by using barcode patrol inspection method. The technical characteristic of RF technology is that it can collect the information in the RF tag in a special environment, and its maximum reading distance can reach about two meters. Using the RF inspection method can easily make up for the shortcomings of the barcode inspection method. The solution is to apply RFID technology to the process of road inspection, install RFID RF tags on the power equipment, and the inspectors can collect the information of the power equipment to be inspected from a long distance, and update the equipment information corresponding to the tags at the same time, so that the information data can be transmitted to the background information system in real time for data analysis and recording

IV. high performance and high reliability of intelligent inspection system

● advanced PDA application

the system adopts the latest mobile operating system PDA terminal based on micros0fl. The portable operation is very convenient and the operation is stable. It greatly improves the convenience and accuracy of patrol inspection. PDA has large storage capacity and enough space to store patrol data. PDA is equipped with high-performance CPU, which provides stronger processing power than other handheld functions. PDA also provides Chinese character input function and full screen handwriting function, which can directly input characters and Chinese characters by handwriting on the screen

● flexible defect description library

the system uses common sentence templates for defect entry. Normative description and record of defects, so as to standardize defect management

● secure data backup

in order to ensure the security of data, the system provides automatic data backup and recovery function. Data backup: the system is set to automatically backup data to the PDA extended SD card when the battery power is lower than 25% or when exiting the system. The backed up data includes: PDA end installation program, user registration information, equipment account information, historical patrol data and patrol tasks. Data recovery: when the data of PDA terminal is lost, install the PDA terminal program directly through the SD card backup installation program, and lead the user registration information, equipment account information, historical patrol data and patrol tasks before running the program

● perfect statistical analysis

detailed analysis and treatment of inspection records and defects is an important aspect to improve the application value of equipment operation management software products. The system intuitively expresses the inspection data and defects through charts, statements and other forms, which is convenient for managers to make correct decisions

● integration with MIS system

due to historical reasons, many computers often use 70% of their cobalt production capacity for systems in the battery field. This system specially designs the configuration interface for the original MIS system to realize data sharing and synchronization. Make full use of the original production MIS. The application of RFID in power equipment inspection provides a more reliable guarantee for the security of power equipment. The application of RFID in the power industry will certainly make the work of the power system to a new level, create huge economic benefits, and open up a broader market space. (end)
