Abstract

The invention discloses an oil liquid quality detection method and system. The method comprises producing an original excitation signal, carrying out amplification adjustment on the original excitation signal to obtain a target excitation signal, carrying out action on a sample sensor corresponding to sample oil and a reference sensor corresponding to reference oil by the target excitation signal to obtain a sample response signal corresponding to the sample sensor and a reference response signal corresponding to the reference sensor, carrying out differential treatment on the sample response signal and the reference response signal to obtain a difference signal, carrying out amplification adjustment on the difference signal to obtain an acquisition signal, carrying out impedance detection on the acquisition signal to obtain a target impedance spectrum response signal, and carrying out computing by the pre-stored reference impedance spectrum response signal of the reference oil and the target impedance spectrum response signal to obtain a sample oil liquid quality analysis result. The method effectively improves oil liquid quality detection sensitivity and accurately acquires a change case of factors in an oil liquid.

Description

technical field [0001] The invention relates to the technical field of oil detection, and more specifically, to an oil quality detection method and system. Background technique [0002] According to relevant data, most of the failures of mechanical equipment and hydraulic components are caused by oil pollution. Therefore, the detection of oil quality is of great significance. [0003] At present, the widely used oil quality detection method is the dielectric constant method. The conventional oil quality detection method based on the dielectric constant method is specifically to convert the change of the dielectric constant of the oil into the measurement of capacitance or voltage at a single frequency point, and then determine the oil quality. However, the change in the dielectric constant of the oil itself is small, so that the change in the voltage or capacitance caused by it is relatively weak; and the base signal generated by the sensor used in the process of measuring ...
