The utility model provides a pixel coloring method in transformer station remote browsing. The method comprises the following steps that a main station receives a picture file sent by the transformer station and then analyzes the same; the main station receives a public resource definition file sent by the transformer station and then analyzes the same; the main station receives detection point data sent by the transformer station, then gets a required displaying state according to a pixel color mapping table after analysis and dynamically draws on a main station picture; and the main station receives changeable detection point data sent by the transformer station in real time, gets a required displaying state according to a pixel color mapping table after analysis and dynamically draws on the main station picture. The pixel coloring method can solve a problem that pixel color and flicker state changes in monitored pictures in the transformer station cannot be accurately transmitted to the main station, so displaying color flicker states of each pixel in the main station picture during remote browsing is remained the same as relative pixels of the transformer station and therefore remote browsing displaying effect and user experience are enhanced.
