Problems solved by technology
At present, dual-network redundancy technology is required to be applied in actual production. For dual-network redundancy, two network ports are often connected to a CPU at the same time. Although this is simple, it requires high CPU and handles two The IEC61850 protocol coming from the network port reduces the real-time and reliability of communication analysis

Description
technical field [0001] The invention relates to a multi-network port and multi-CPU protocol conversion device based on a switching chip, which belongs to the technical field of electronic communication. Background technique [0002] The IEC61850 standard is the only global common standard in the field of power system automation. Through this standard, the engineering operation standardization of smart substations is realized, and the engineering implementation of smart substations becomes standardized, unified and transparent. No matter which system integrator builds the smart substation project All can understand the structure and layout of the entire substation through the SCD (system configuration) file, which plays an irreplaceable role in the development of intelligent substations. IEC61850 includes MMS (Manufacturing Message Specification) messages, GOOSE (Generic Object-Oriented Substation Events) messages, SMV (Sampling Measurement Value) messages, etc. GOOSE message...
