The Application of NFC Passive Lock in the Power Industry

Situation of electric power industry

my country's electric power informatization market has a huge space. From 2017 to 2021, State Grid's investment in informatization generally shows a fluctuating upward trend .

Due to the high security and stability requirements of the power industry, customers in the power industry have high requirements for the advancement and reliability of information technology products and services. By the end of 2021, the market size of the industry has exceeded 75 billion yuan.

With the continuous expansion of the scale of the power grid , the equipment in the power grid is increasing year by year, and the production operations are frequently crossed, making it difficult to authorize and record;

With more and more equipment, it is becoming more and more difficult to manage various power equipment, and the phenomenon of outdoor equipment theft and damage is becoming more and more serious, and the difficulty of superior supervision is also increasing. How to solve the current management problems and how to solve safety problems through effective technical means are the safety management problems that the electric power industry is eager to solve.

About NFC technology

The passive lock system based on NFC (that is, Near Field Communication) technology uses radio frequency RFID, wireless communication, infrared sensors, global positioning and other technologies to construct a system that covers everything in the world, interconnects, automatically identifies and A network of information sharing. It uses the operation mode of large integration and cloud computing to provide management and service functions such as online intelligent identification, positioning, tracking, monitoring, control, maintenance and data statistics, and realize the integration of management, control and operation.
