AI Technical Summary

Technical Problem

Existing power distribution equipment condition monitoring products have a wide variety of sensor interfaces, different sampling frequencies, and numerous data interfaces, which makes CPU processing difficult and data interaction between multiple CPU modules complex; at the same time, the fixed method of functional modules makes it difficult to quickly replace them.

Method used

An IED intelligent electronic device was designed, comprising a chassis, a fixing mechanism, an execution module, a bus backplane, and a display panel. The fixing mechanism, which uses a limiting chamber, locking holes, locking rods, a limiting plate, a strong spring, an electromagnet, and a limiting hole, is combined with an Ethernet switching chip to achieve a modular design. The execution module can be quickly fixed and disassembled using an electromagnet, and a 9-port 100M Ethernet switching chip is used to support data interaction between the main control board and the function board.

Benefits of technology

It enables rapid fixing and disassembly of the execution module, simplifies the operation process, reduces maintenance costs, improves the stability and reliability of the device, optimizes the modular design and overall monitoring costs, and meets the performance requirements of different data acquisition and interaction.
