when the digital processing module receives the pressure data transmitted by the digital acquisition module, carrying out extremum removal and averaging on the pressure data acquired in each time period to obtain pressure average values, sequencing the obtained pressure average values according to the acquisition time, drawing coordinate points in a binary coordinate system of the pressure average values and the acquisition time, connecting adjacent coordinate points, and calculating the slope of each section of connecting line;
if the slope of each section of connecting line is the same and the slope is zero, judging that the pressure of the hydraulic oil on the filter screen is stable, and no impurity larger than the filter screen holes exists in the hydraulic oil; if the slope of each section of connecting line is the same and is larger than zero, the pressure of the hydraulic oil on the filter screen is determined to be gradually increased, impurities larger than the meshes of the filter screen exist in the hydraulic oil, the impurities are uniformly distributed and more in quantity, and the weight change of the filter screen is compared after the filtering operation is completed; if the slope of each section of connecting line is the same and the slope of the rear section is zero, judging that the pressure of the hydraulic oil on the filter screen gradually increases and then tends to be stable, distributing impurities in the hydraulic oil uniformly and reducing the number of the impurities, and comparing the weight change of the filter screen after the filtering operation is completed;
if the slope of each section of connecting line is different and the connecting line is in an ascending trend, judging that the pressure of the hydraulic oil on the filter screen is gradually increased, and comparing the weight change of the filter screen after the filtering operation is finished because impurities with different sizes exist in the hydraulic oil;
the number of modules are used for calculating the difference value between the front pressure data detected at the filter screen before the filtering operation and the rear pressure data detected at the filter screen after the filtering operation to obtain a pressure change value, and comparing the obtained pressure change value with a first set pressure value and a second set pressure value; setting a second pressure value as pressure data of the filter screen when hydraulic oil with corresponding viscosity passes through the filter screen;
if the pressure change value is greater than or equal to the set pressure value I, judging that more impurities exist in the hydraulic oil and the hydraulic oil needs to be replaced; if the pressure change value is smaller than the first set pressure value, judging that impurities in the hydraulic oil are less, and comparing the pressure change value with the second set pressure value; if the pressure change value is smaller than the second set pressure value, the hydraulic oil is judged to be still usable without replacement.
