The application relates to the field of artificial intelligence medical technology and discloses an early esophageal cancer screening method and system based on artificial intelligence, which comprises the following steps: preparing an obtained esophageal epithelial cell sample of a subject into a single-layer cytological smear, generating an original digital pathology image through optical scanning; extracting independent cells therefrom, calculating local spatial moment parameters of the independent cells; determining the geometric principal axis direction and stretching degree of the independent cells based on the local spatial moment parameters; judging whether the stretching degree exceeds the length-width ratio benchmark constant of normal esophageal squamous epithelial cells, if yes, applying a local two-dimensional affine transformation to the independent cells along the geometric principal axis direction to offset the mechanical stretching deformation caused by sampling, and generating calibrated cell image data; inputting the calibrated cell image data into an artificial intelligence classification module, extracting cell pathological features based on a deep convolutional neural network, and outputting a screening diagnosis result. The application offsets cell deformation interference and improves screening accuracy.

This utility model discloses an external frame-type bulge monitoring power battery pack, including a cell module, a housing, a cover, a battery control system, and a cell bulge detection mechanism. The cell module is composed of multiple square cells arranged linearly and closely together, covered by an insulating plate and fixed by an external frame. The cell module is located inside the housing, and the cover covers the battery control system and closes to the housing to encapsulate the cell module inside the battery box. The cell bulge detection mechanism is set on the external frame and is used to detect the shape changes of the square cells caused by bulging in real time. This utility model achieves stable cell assembly and cell deformation monitoring through the cell bulge detection mechanism integrated on the external frame, improving the early safety warning capability of the battery pack.
