Wherein, the colors corresponding to different atmospheric corrosivity grades are different, such as: the atmospheric corrosivity class is divided into 7 classes,the colors from the highest grade to the lowest grade are red, orange, yellow, green, blue and purple respectively. Thus, atmospheric corrosion dynamic change in the corresponding area can be visually observed through different colors, observers are timely warned, and according to the determined W1、W2And W3The maximum value of the three values is determined, so that the text corresponding to the maximum atmospheric environment data is inserted into the corresponding sub-area, and the main environmental factors influencing the corrosion rate at the current time point can be further determined.
