description The invention discloses a VRML (Virtual Reality Markup Language) file binary compression coding method for a power transmission operation and maintenance scene, which overcomes the problems of long downloading time, low network transmission speed and high power transmission operation and maintenance overhead caused by redundant information and overlarge file size in the VRML file in the power transmission operation and maintenance scene in the prior art. Comprising the following steps: S1, dividing a geometric model defined by the VRML to obtain a plurality of sub-domains; s2, analyzing an attribute feature relationship between the current sub-domain and the previous sub-domain, performing binary compression coding on the sub-domains according to an analysis result to obtain a bit stream, and storing an attribute feature stack; and S3, storing the obtained bit stream according to a sub-domain arrangement sequence, wherein only the attribute feature value of the corresponding sub-domain coded as 1 is stored du
