The invention particularly relates to a multi-beam system fault diagnosis method of an underwater cruise device, which comprises the following steps that: step 1, a plurality of slave machines convert electric signals of an underwater acoustic transducer into image data, and a host machine performs preprocessing of noise reduction, edge detection and graying on the image data to obtain image data; the main control computer receives the preprocessed image data and marks the preprocessed image data as an initial image; 2, sequentially connecting a multiplexer of the signal verification module with a slave according to an array sequence, sampling image data connected with the slave and an electric signal of an underwater acoustic transducer, and converting the electric signal into a verification image by a simulator according to the electric signal; step 3, the signal verification module inputs the image data and the verification image into a neural network algorithm to obtain a verified comparison image unit; and step 4, the main control computer receives each comparison image unit of the signal verification module, the main control computer segments and compares the initial image and the comparison image, screens the image blocks of which the comparison values are greater than a preset threshold value, and tracks the slaves corresponding to the image blocks.
