The invention discloses a track safety detection system based on improved AlexNet. An abnormal vibration signal judgment module of the track safety detection system determines that a driving vibration signal of each driving vibration signal detection area in each selected historical period is a normal driving vibration signal or an abnormal driving vibration signal; the vibration signal data set establishing module forms a model data set; the data enhancement module performs data enhancement on the model data set, and divides vibration signal data in the model data set after sample expansion into a training set, a verification set and a test set; the convolutional neural network model construction module constructs a convolutional neural network; a model training module uses the training set to train an AlexNet model; and the signal test module determines the track safety condition of the to-be-tested driving vibration signal test area. According to the invention, full-time and full-domain detection can be carried out on the track, and early warning can be carried out on external construction, track abnormity, personnel invasion and other problems.
