TECHNICAL FIELD

[0001] The utility model relates to the technical field of distribution equipment, specifically to intelligent distribution equipment. BACKGROUND

[0002] In the field of aviation, especially in military and special civilian aircraft, the reliability and stability of the power management system are crucial. The power system not only provides stable energy for each system of the aircraft, but also maintains normal operation under various extreme conditions to ensure flight safety and the smooth completion of tasks. With the rapid development of electronic technology, modern aircraft have increasingly high requirements for power systems, especially in special task aircraft such as rain enhancement machines, reconnaissance aircraft, early warning aircraft, etc. These aircraft need to perform complex tasks, and higher requirements are put forward for the stability, reliability, and intelligent management of the power system.

[0003] Traditional aircraft power systems are usually composed of simple distribution panels and some basic protection devices. These systems often lack intelligent management functions and cannot effectively monitor and control each power-consuming device. In the event of power system failures such as overload and short circuit, the reaction speed of traditional systems is slow, and the fault handling capability is weak, which may lead to serious equipment damage or even flight safety accidents. In addition, with the increase of electronic equipment on the aircraft, higher requirements are put forward for the flexibility and expandability of the power system.

At the same time, these aircraft often need to work in extreme environments such as high temperature, low temperature, high humidity, and vibration when performing tasks, which puts higher requirements on the stability and adaptability of the power system.

[0005] With the development of microelectronic technology and computer technology, intelligent power management systems have become a research hotspot in the field of aviation. Intelligent power management systems can realize real-time monitoring, fault diagnosis, automatic protection, and remote control of aircraft power, greatly improving the reliability and safety of aircraft power systems. However, most of the intelligent power management systems on the market are still in the research and development stage, and are expensive, making it difficult to meet the needs of large-scale equipment. Therefore, a new intelligent distribution equipment has become a problem that needs to be solved by technical personnel in the field. INVENTION CONTENTS
