The invention discloses a railway wagon folding type manual brake shaft falling fault identification method and system, and belongs to the technical field of railway wagon detection. The objective ofthe invention is to solve the problem of low working efficiency of existing manual detection and the problem that a neural network cannot ensure accuracy, a false alarm rate and detection efficiency at the same time. The method provided by the invention comprises: firstly, taking a truck folding manual brake axle image, then adjusting the image to a uniform size, and carrying out prediction through a Faster RCNN; carrying out the step of performing prediction through the Faster RCNN network comprises the following sub-steps of predicting a mounting base at the tail part of a folding type manual brake shaft, a manual brake handle at the head part and a connecting part of a bracket connected with a vehicle body through the Faster RCNN network; reducing the data precision to FP16 in the prediction process; and according to a prediction result, carrying out fall-off fault identification of the folding manual brake shaft. The method is mainly used for identifying the falling-off fault of the folding type manual brake shaft.
