Online early warning method and system for water cooling system

The invention provides an online early warning method and system for a water cooling system, and relates to the technical field of abnormal early warning, and the method comprises the steps: monitoring the operation state data of the water cooling system in real time; performing data cleaning on the operation state data to obtain standard operation state data; if the standard operation state data is larger than a preset value, the pressure difference of two inlet and outlet valves is calculated; performing consistency judgment according to the pressure difference, and calculating a consistency coefficient; setting an early warning threshold value, comparing the early warning threshold value with the consistency coefficient, and if the consistency coefficient is greater than the early warning threshold value, generating an early warning signal; and performing visual early warning according to the early warning signal. According to the invention, the technical problem that the stable operation of the water cool
