Technical Field

The core of smart grid is to realize the digitization, networking and intelligence of power system, and the remote monitoring and control technology of power distribution cabinet, as a key component of power system, has become an important part of smart grid construction.

[0003] Traditional power distribution cabinets have many limitations in data collection, processing and communication. First, in terms of data collection, traditional distribution cabinets often use manual inspections or simple sensor monitoring methods, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate or missing data. Secondly, in terms of data processing, the traditional distribution cabinet has a low degree of intelligence and lacks the ability to deeply analyze and process data, making it difficult to promptly discover and deal with potential fault hazards. Finally, in terms of communication, the communication protocols of traditional distribution cabinets are not unified, the data transmission speed is slow, and it is easily interfered by the external environment, resulting in poor remote monitoring and control effects.

[0004] In addition, with the development of smart grids, higher requirements are placed on the safety and stability of power distribution cabinets. Traditional distribution cabinets often use mechanical locks or simple electrical locks for electrical interlocking. This interlocking method has problems such as low reliability and easy cracking, and cannot meet the security requirements of smart grids. At the same time, during data transmission, traditional distribution cabinets lack effective data encryption and verification mechanisms, which can easily lead to data leakage or tampering, thus affecting the stable operation of the power system.
