RFID technology can identify high-speed moving objects and can simultaneously identify multiple labels, the operation is quick and easy. By RFID automatic inspection system, greatly improving the security inspection capabilities of the power industry, so that this work has reached a new level. The use of RFID technology for substation equipment inspection mainly has the following advantages.
First, against external forces, rapid data collection
We know that transmission and distribution lines and equipment are an important part of the power system. They are often in long-term operation and are exposed to nature for a long time. They not only withstand normal mechanical and electrical loads but also are subject to contamination, lightning strikes, Strong winds, floods, landslides, subsidence, earthquakes and bird damage. The above factors will promote the aging, fatigue, oxidation and corrosion of various components on the line. If they are not found and eliminated in time, they may develop into various kinds of faults, posing a great threat to the safety and stability of the power system.
When patrolling based on bar code technology, the bar code labels of perennial outside often can not be read due to the wear or foulness of the outside of the bar code because of the integrity and cleanness of the printed surface of the label based on the characteristics of photoelectric technology The requirements are very high. The RFID's technical characteristics (antifouling, damage, UV and other harsh outdoor environment and strong ability to read a long distance, repeated deletion of information, storage capacity, anti-collision) for this problem to find the best solution. Radio frequency technology uses the principle of radio technology, reading equipment only through the radio waves can quickly carry out data acquisition for two.
Second, the control of security personnel in place, the standardization of information input
Inspection work is divided into two parts: circuit inspection and line inspection. One line inspection work due to the need to cross the mountains, in place of control is particularly important. In order to control the inspector in place rate. Have used "physical recovery" approach. That is, the need to patrol the device in advance tie the mark bar. To be patrolled by the inspector will be the flag to be retrieved. To verify the inspection rate. Bar code technology based on the control of the inspection rate, although the inspector using bar code handheld patrol device can be pasted on the bar code scanning equipment. Collect bar code ID number information, but the bar code is easy to be copied, vulnerable to the shortcomings of the defaced power of the inspectors in place rate can not be guaranteed.
In addition, the work of substation inspection requires inspectors on the substation equipment for regular or irregular inspections, and equipment operating conditions, operating parameters for a simple record. The use of radio frequency reading and writing equipment system can easily patrol work arrangements and defect data collection. In the management of radio frequency equipment in the field through the inspection terminal collection of information and real-time transmission of data backstage analysis of the background system to achieve the inspection in place control and defect information input standardization work.
Third, special environmental inspection, to protect the safe operation of power supply system
For some special environment inspection work, such as inspection equipment that is in high-pressure environment or is clamoring for a certain height of the device, the use of bar code inspection is difficult to complete the inspection work. The technical characteristics of radio frequency technology lies in that it can collect the information in the radio frequency tag in a special environment and can reach a maximum reading distance of up to two meters. By using the radio frequency inspection method, it is easy to make up for the shortage of bar code inspection methods.
Solution The application of RFID technology in the line inspection process, the installation of RFID tags RFID equipment, inspection personnel can patrol the power equipment for long-distance information collection, and update the label corresponding to the device information, so that Information data real-time transmission background information system for data analysis, record.
Fourth, intelligent inspection system of high performance, high reliability
Advanced PDA application
The system uses PDA terminal based on Micros0fl latest Mobile operating system. Carrying operation is very convenient and stable operation. To a great extent improve the convenience of inspection, accuracy. PDA storage capacity, there is enough space to store inspection data. PDA configuration of high-performance CPU, than other handhelds to provide more processing power. PDA also provides Chinese input function and full-screen handwriting function, can be directly on the screen input characters and Chinese characters.
Flexible defect description library
The system uses common sentence templates for defect entry. Defects of the normative description and record, so that defect management standardization;
Secure data backup
In order to ensure data security, the system provides automatic data backup and recovery functions. Data Backup: The system automatically backs up the data to the SD card of the PDA when the battery power is lower than 25% or exits the system. The backup data includes PDA installation program, user registration information, equipment accounting information, historical inspection data And inspection mission. Data Recovery: When the PDA terminal data is lost, the PDA terminal program is directly installed through the SD card backup installation program, and the user registration information, equipment accounting information, historical inspection data and inspection tasks are run before running the program.
Improve the statistical analysis
Patrol records, defects for a detailed analysis and processing is to improve the equipment operation and management software products an important aspect of the value. The system through the charts, reports and other forms of inspection data, the defects of the intuitive presentation, easy for managers to make the right decisions.
Integration with MIS system
Due to historical reasons in power enterprises, there often exist many computer application systems. The system of the original MIS system designed to configure the interface to achieve data sharing and synchronization. Make full use of the original production MIS. RFID inspection of electrical equipment should be, for the safety of electrical equipment to provide a more reliable protection. The application of RFID in the power industry will surely bring the work of the power system to a new level and create enormous economic benefits and open up a broader market space.
