First, system overview:
Power equipment inspection system is a basic work to effectively ensure the safety of power equipment, improve the reliability of power equipment, and ensure the minimum failure rate of power equipment. At present, domestically adopted methods of manual patrols and manual paper media recordings have many deficiencies such as many human factors, high management costs, inability to supervise the work of patrolling officers, and low degree of informatization of inspection clerk.
The RFID power inspection program introduces the current advanced RFID technology +GPS (satellite positioning system) +CDMA/GPRS technology, mainly to solve the following three important issues in the equipment inspection work: 1. Invalid inspection, missing inspection, or 2. Inaccurately; 2. The manual inspection results are inefficient, easy to miss or wrong; 3. It is difficult for managers to understand the circuit conditions in a timely, accurate and comprehensive manner, and it is difficult to formulate the best maintenance and repair programs.
Second, the system works:
During inspections, the inspector automatically sends a message to the center through the handset (every 2 minutes, interval can be set), and reports information such as the position and time of the current inspector. If a fault is found, he or she will The type of failure, device number, and current handheld RFID information are sent to the monitoring center.
The monitoring center receiver receives the report information and stores it. The system reads the information received by the receiver through the system, decomposes the time, place, type of equipment, and discoverer of the failure, and automatically stores the data information in the database server and publishes it on the Internet.
The monitoring terminal uses the RFID system to display the inspection status on the software in real time, such as displaying the fault points found by various inspection personnel, the emergency status of various types of faults, the processing status, the current status, and the position of each inspection personnel at a certain moment. Inspection route.
The tower is affixed with an RFID tag. Through the globally unique identifier, the patrolling personnel must personally go to the site to obtain the RFID identification code, thereby restraining the staff from actually checking in place. At the same time, firstly, the latitude and longitude data of each base tower of all the lines that need to be patrolled are input into the server and the handset. During the inspection process, the lineman locates the latitude and longitude of the towers to be inspected through the GPS global positioning system. It is consistent with the original data input. At the same time, the patrolled information is recorded in the handset. After the patrol is returned or the CDMA/GPRS network is used in the field, the recorded information is input into the server and compared. In this way, abnormal conditions in the operation of the line can be discovered in time so that processing can be carried out in the shortest possible time, thereby ensuring the safety of the line. Due to the need to compare the data collected in the inspections with the server, it can effectively promote the improvement of the quality of circuit inspections, ensure the arrival rate of line inspection personnel, and eliminate missed inspections and incomplete inspections.
The system can also collect, analyze, and analyze various historical data stored in the database, and display the frequency and occurrence of a certain fault in a certain period of time in the format of various types of charts or reports for managers to predict and analyze. Strengthen management and formulate countermeasures to achieve the purpose of pre-control, to reduce the incidence of accidents and ensure the smooth progress of safe production.

Fourth, system advantages:
1) High weather resistance: able to withstand the sun, rain and rain, tolerate large temperature changes (usually -30 ~ 70 °C), and even withstand flooding;
2) Strong adaptability: automatic identification can be read under harsh climatic conditions; reading of automatic identification is not disturbed by substation environment;
3) Strong anti-counterfeiting capabilities: The logo cannot be copied and counterfeited, and human cheating is avoided;
4) Easy to install: It can be buried directly on the cement base, and the installation equipment is simple and the process is simple;
5) Strong against vandalism: able to resist general man-made destruction; able to prevent malicious destruction of children or livestock;
6) Long service life: The service life is more than 10 years;
7) Convenient operation and maintenance: maintenance free, reducing management costs;
