The invention relates to a multi-sensor traction machine excitation loss monitoring method based on one-dimensional multi-scale convolution. The method mainly solves the technical problem that a multivariable and nonlinear relation contained in a traditional convolutional network is difficult to accurately describe. According to the technical scheme, the excitation loss monitoring method comprises the specific steps that S1, excitation loss sensitive characteristic parameters are collected from existing data, and the types and arrangement forms of multiple paths of needed sensors are determined; s2, acquiring field loss characteristic signal data of the permanent magnet synchronous traction machine under typical working conditions through a multi-path sensor, and constructing a representative field loss characteristic database; s3, preprocessing the characteristic signal data in the field loss characteristic signal database according to the physical attribute and the sensitive expression form of each field loss sensitive characteristic, and updating the field loss characteristic database; s4, building a lightweight network model; s5, determining the output type of the network according to the field loss degree interval division; and performing network configuration and network training.
