Step one：Parsing SCD file, the SCD file represents transformer substation system configuration describing document, in extracting IED
Inputs, the IED represents intelligent electronic device, offside IED titles is obtained by iedName fields, by intAddr fields
Obtain the reception physical port for receiving empty terminal and this empty loop；
Step 2：Parsing SPCD files, the SPCD representation of file transformer station physical configuration describes file, obtain cell, screen cabinet,
Device, board, the physical port of device, by IntCore elements the connection of physical port involved by screen cabinet internal optical fiber is obtained
Relation, the annexation for shielding cabinet, device, physical port between screen cabinet involved by optical cable is obtained by Core elements；
Step 3：The reception physical port in empty loop is as search starting point with step one, in traversal step two in SPCD files
Physical port annexation, includes two physical ports, when one of port is searched in physical port annexation
During physical port, then using another port as the progressively unidirectional search forward of next search starting point, until the physics end searched for
Mouth corresponding device is IED equipment or switch device；If the search end is IED equipment, judge whether this IED title is step
Offside IED titles in one, if so, then this physical pathway is the physical pathway in empty loop in step one；If the search end is
Switch device, then with whole physical ports of switch be again that new search starting point continues to search for forward, final iterative search
To IED equipment, then judge that whether this IED title is the offside IED titles in step one, if so, then this physical pathway is as walked
The physical pathway in empty loop in rapid one.
