Converter valve cooling capacity multidimensional analysis early-warning method and system

The invention discloses a converter valve cooling capacity multidimensional analysis early-warning method and system and relates to the field of converter valve monitoring technologies. The system comprises early-warning units, a man-machine interaction device, a central processing unit and a data collection module, wherein the data collection module is used for collecting a state quantity of a converter valve cooling system and transmitting the state quantity to the central processing unit through a data collection interface; the central processing unit is used for assessing the cooling capacity of the state quantity and outputting an early-warning signal of the assessment result through an advanced early-warning unit, a first early-warning unit and a second early-warning unit respectively; and the man-machine interaction device is used for inputting a user instruction and displaying a monitored value of the state quantity. According to the method, a cooling capacity quantitative model is established from di
