[0002] The application of power intelligent data communication gateways (usually referred to as power gateways or intelligent gateways) in power systems primarily enables communication between substations and main station systems such as dispatching and production stations. They provide data, models, graphics, and file transmission services to enable main station systems to perform functions such as substation monitoring and control, information querying, and remote browsing. Current research mainly focuses on the software level, improving the operational quality of communication systems, but neglects research on the hardware level of power intelligent data communication gateways. Therefore, in practical applications, the following problems are encountered:

[0003] Stability and Reliability: Due to the continuity and criticality of power supply, smart gateways must ensure extremely high operational stability and reliability; any failure could lead to serious consequences. Insufficient Scalability and Flexibility: If the smart gateway's design is not flexible enough to accommodate future needs by adding new functions or interfaces, it may become obsolete as the power grid expands and technology advances.

[0004] To address these issues, we designed a smart power data communication gateway. Utility Model Content
