Abstract

The invention discloses a method for detecting hidden faults of multiple train sets. The method comprises: collecting images of different preset positions of multiple train sets at preset time intervals, and storing the collected images; The components contained in the images of different preset positions and the pre-established mapping relationship are obtained to obtain the concealed fault detection rule of the EMU; the mapping relationship is the corresponding relationship between the components and the concealed fault detection rule; according to the recent several The images of different preset positions of the EMU collected once and the hidden fault detection rule are used to detect the faults of the components contained in the images of different preset positions of the EMU collected in one of the most recent times. The hidden fault detection method of the multiple train set of the invention improves the concealed fault detection capability of the multiple train set and the early warning capability of the fault occurrence, enhances the safety protection level of the multiple train set operation, and provides an effective means for preventing the "sick" operation of the multiple train set.

Description

technical field [0001] The invention relates to the technical field of detection of running faults of multiple train sets, in particular to a detection method for concealed faults of multiple train sets. Background technique [0002] When the EMU is running at high speed, any small and subtle fault may cause a major accident, so it is very important to improve the accuracy of the detection of the hidden fault of the EMU. [0003] However, most of the existing EMU operation fault detection methods only realize the inspection of the deformation, displacement, and falling off of the major components, and do not really detect some hidden faults such as loose bolts, broken anti-loosening wires, and misplaced anti-loosening marks. Realize maintenance and protection. Therefore, EMUs often run "sick". Contents of the invention [0004] The technical problem to be solved by the invention is the problem that the existing detection method for the running fault of the multiple train...
