Intelligent substation process level switch visual operation and maintenance system

The invention discloses an intelligent substation process level switch visual operation and maintenance system, which establishes communication connection with a process level switch, receives SV/GOOSE messages, monitors the operation state of the process level switch, performs visualization of physical links, generates a two-dimensional code by one key, and directly obtains process level switch information by scanning the two-dimensional code through a visual terminal. The system is reasonable in design and simple in principle, is used for realizing link connection visualization and operationstate visualization of each port of the process layer switch, has the characteristics of real-time uploading, quick query, accurate positioning and timely alarm. 1) Physical links and virtual links of the process layer switch are in one-to-one correspondence for real-time online visual monitoring, monitoring information is uploaded to a WEB server in real time, an inspector scans a two-dimensional code label on a switch,
