The invention relates to a method for diagnosing faults in a high-pressure common rail system of an engine, which comprises the following steps of: breaking at least one cylinder in an engine by adopting a cylinder separation technology; measuring the rail pressure in the high-pressure common rail system after cylinder breakage on the basis of a crankshaft rotating angle; filtering practical rail pressure measured in real time to form input rail pressure; sampling the input rail pressure at a predefined crankshaft rotating angle interval to form a sampling signal; selecting the sampling signal positioned in a rail pressure stable area of the high-pressure common rail system as a characteristic sampling point of rail pressure; filtering the characteristic sampling point to generate rail pressure obtained after cylinder breakage; solving a rail pressure difference value of the rail pressure obtained after cylinder breakage and factory rail pressure; and when the difference value is higher than a preset threshold value, judging that the high-pressure common rail system has a fault. The method also comprises the step of compensating oil spray amount and oil pumping amount which are associated with the rail pressure difference value into the factory oil spray amount and oil pumping amount if the high-pressure common rail system has the fault so as to calibrate the fault.

The invention relates to a residual network rolling bearing fault diagnosis method based on time-frequency analysis. The method comprises the following steps of S1. collecting vibration signal data, converting a vibration time domain signal of a rolling bearing into a time-frequency map by using short-time Fourier transform, and converting the time-frequency map into a two-dimensional gray level time-frequency map; and S2. performing feature extraction on the signal by using a residual network, and diagnosing a fault type of the bearing, wherein the input of the residual network is the gray level time-frequency map generated in the step S1, and the output of the residual network is a fault diagnosis result.
