Abstract: A cooperative control method and system for electro-hydraulic hybrid braking of a middle-low speed maglev train is provided, which relates to the field of vehicle braking control. The method includes: denoising operation data of a middle-low speed maglev train; using a controlled autoregressive integrated moving average model as an electro-hydraulic hybrid braking process model for the middle-low speed maglev train, and processing denoised operation data by using a least square method to determine parameters in the controlled autoregressive integrated moving average model; establishing a generalized predictive control model with time lag compensation according to the controlled autoregressive integrated moving average model and a Smith predictor; and performing cooperative control on an electro-hydraulic hybrid braking process of the middle-low speed maglev train by using the generalized predictive control model with time lag compensation.

Abstract: A machine vision detection method includes receiving a three-dimensional image of a part to be detected including a first part and a second part, determining a plurality of sampling positions that satisfy sampling conditions, acquiring first sample data of the three-dimensional image of the first part at sampling positions and second sample data of the three-dimensional image of the second part at the sampling positions, calculating a first height difference between a plurality of first sample data and a second height difference between a plurality of second sample data, calculating a third height difference between the first sample data and the second sample data, and determining that the part to be detected is unqualified when any one of the first height difference, the second height difference, and the third height difference fails to meet a preset detection criterion.

Abstract: The present application relates to a method, apparatus and system for inspecting a cell crush, a computer device, a storage medium, and a computer program product. The method may include: acquiring images of a flowing cell assembly by a high-speed image acquisition device; extracting image features from the images of the cell assembly; performing similarity matching between the image features and a preset crush model to obtain a similarity matching result; and obtaining a cell crush inspection result based on the similarity matching result.
