Hydraulic oil quality monitoring method, device and system

The invention provides a hydraulic oil quality monitoring method, device and system, and belongs to the technical field of hydraulic oil monitoring. The hydraulic oil quality monitoring method comprises the steps of obtaining hydraulic oil samples of equipment under different working conditions and different environments; performing data association on the detected quality evaluation index of the hydraulic oil sample and the working condition information and the environment information of the current equipment, and storing the data in a database; establishing a characteristic model of hydraulic oil quality evaluation index change; and matching the quality evaluation index of the target hydraulic oil and the working condition information and the environment information of the current target equipment with data stored in the hydraulic oil quality evaluation index change feature model, and judging the quality state of the target hydraulic oil according to a matching result. The method can judge the quality condi
