With the development of my country's electric power industry, power lines continue to extend, power equipment gradually increases, power networks become increasingly dense, and the task of protecting power facilities becomes heavier and more arduous. It is reported that most of the sudden power outages are caused by the damage of power facilities by external forces such as illegal construction on construction sites. Due to the increase in construction, vicious accidents such as cable digging, car collision, and channel damage have occurred frequently, causing great harm to production and people's lives, and its social impact and economic losses are difficult to calculate.

At present, the protection measures for power equipment mainly adopt the method of manual inspection. Due to the complex situation of the construction unit, the difficulty of supervision, and the coordination of multiple departments, the traditional protection measures for power equipment can no longer meet the current actual situation. It mainly has the following deficiencies:

1) Lack of real-time supervision means: manual inspection is adopted. Due to the large area of the power grid and the distribution of equipment, it is impossible for manual inspection to monitor all electrical equipment 24 hours a day. Therefore, destructive construction often cannot be detected and prevented in time.

The personal information of construction personnel, construction units, project leaders and other information are not uniformly managed. When early warnings or accidents occur At that time, it was impossible to find the relevant person in charge at the first time.

4) Lack of unified deployment management for the entire power facility protection area: In the power facility protection area, there is no real-time and unified management platform, resulting in problems such as untimely discovery of problems, low efficiency of communication and deployment of personnel, and waste of human resources.

Radio frequency identification technology (RFID) is a non-contact automatic identification technology, which has the characteristics of identification work without manual intervention, multi-label long-distance reading, low environmental requirements, long service life, data can be encrypted, and stored information can be changed , high reliability, convenience and quickness, etc., will become an inevitable trend in the future development of the power industry.
