RFID technology transformation equipment inspection highlights the advantages

RFID technology can identify high-speed moving objects and can identify multiple labels at the same time. The operation is quick and easy. Through the RFID automatic inspection system, the security inspection capability of the power industry has been greatly improved, and this work has reached a new level. The use of RFID technology for transformer inspection equipment has the following advantages.

First, against external forces, rapid data acquisition

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 and not only bear the effects of normal mechanical loads and electrical loads, but also suffer from pollution, lightning strikes, Strong winds, floods, landslides, subsidence, earthquakes, and bird damage, etc. The above factors will promote aging, fatigue, oxidation and corrosion of various components on the line. If they are not discovered and eliminated in time, they may develop into various types of failures, posing a great threat to the safety and stability of the power system. When bar code technology is used to perform power inspection work, bar code labels that are often outside the world often cannot be read because of the external wear or contamination of the labels, because bar codes are based on the characteristics of optoelectronic technology and the integrity of the printed surface of the label and the degree of cleanliness. The requirements are very high. The technical characteristics of RFID itself (such as anti-fouling, damage, and ultraviolet light, and other harsh outdoor environments, long reading distances, repeated deletion of information, large storage capacity, and anti-collision) have found the best solution to this problem. Radio frequency technology adopts the principle of radio technology, and the reading device can quickly perform data acquisition by radio waves only.

Second, control security personnel in place rate, standardized information input

The patrol work is divided into two parts: transformer inspection and line inspection. Among them, due to the need to overhaul mountains and patrols, the control work in place is particularly important. In order to control the rate of inspectors in place. Have used "real recovery" method. That is, the device to be inspected is tied to the device in advance. At the beginning of the patrol work, the inspector will retrieve the signpost. To verify the inspection in place rate. When bar code technology is used to control the patrol arrival rate, although the inspector uses a bar code hand-held patrol device to scan the bar code pasted on the device. Gathering the ID number information in the bar code, but the disadvantage that the bar code is easy to be copied and vulnerable to being defaced, makes the power patroller's in-place rate unable to be guaranteed. In addition, the inspection work of transformers requires the inspectors to make regular or irregular inspections of the substation equipment, and to record the operating status and operating parameters of the equipment. The use of radio frequency reading and writing device system can easily implement inspection work arrangements and defect data collection. The management of radio frequency equipment through on-site inspection collection terminal to the real-time information and data transmission back-end system analysis, to achieve inspection in place control and defect information input standardization work.

Third, special environmental inspections to ensure the safe operation of the power supply system

For patrol work in some special environments, such as patrolling those devices in a high-pressure environment or being trapped in a device with a certain height, it is very difficult to complete the patrol work using a bar code patrol method. The technical characteristics of RF technology lies in the fact that it is possible to collect information in radio frequency tags in a special environment. The maximum reading distance can reach about two meters. The use of RF inspection methods can easily compensate for the lack of bar code inspection methods. The solution applies RFID technology to the process of circuit inspection. RFID equipment is installed with RFID tags. Inspectors can remotely collect information on the electrical equipment required for inspection, and update the equipment information corresponding to the tags. Real-time information data transmission back-end information system for data analysis and recording.

Fourth, the intelligent inspection system of high performance, high reliability advanced PDA applications

The system uses the latest Mobile operating system PDA terminal based on Micros0fl. The carrying operation is very convenient and stable. It greatly improves the convenience and accuracy of inspections. PDA storage capacity, there is enough space to store inspection data. PDAs are equipped with high-performance CPUs that provide more processing power than other handsets. The PDA also provides Chinese character input function and full-screen handwriting function, which can directly input characters and Chinese characters on the screen.

Flexible defect description library

The system uses common statement templates for defect entry. Descriptive descriptions and records of defects that standardize defect management;

Safe data backup

In order to ensure data security, the system provides automatic data backup and recovery. Data Backup: The system sets the backup data to the PDA's extended SD card automatically when the battery power is less than 25% or the system is exited. The backup data includes: PDA installation program, user registration information, equipment accounting information, history inspection data And inspection missions. Data recovery: When the PDA terminal data is lost, the PDA end program is directly installed through the SD card backup installation program, and the user registration information, equipment accounting information, historical inspection data, and inspection task are introduced before the program is run.

Perfect statistical analysis

Detailed analysis and processing of inspection records and defects are important aspects of improving the application value of equipment operation management software products. The system intuitively expresses inspection data and defects through forms such as charts and reports, facilitating managers to make correct decisions.

Integration with MIS system

In the power companies, due to historical reasons, there are often many computer application systems. This system has specially designed and configured interfaces for the original MIS system to realize data sharing and synchronization. Make full use of the original production MIS. The application of RFID in the inspection of power equipment provides a more reliable guarantee for the safety of power equipment. The application of RFID in the power industry will surely make the work of the power system a new level, create huge economic benefits, and open up a broader market space.

Asp Roof Sheet is made of galvanized metal plate and high weather resistant synthetic resin plate by advanced high temperature hot pressing process. Therefore, compared with ordinary resin tile, it has stronger weather resistance and corrosion resistance, making its service life reach 25-35 years in various corrosive environments, especially suitable for roof tiles of various acid pickling workshops, chemical plants, steel structure plants, warehouses, etc. And we can produce a variety of colors to meet the aesthetic needs.
