The invention provides a fluorescent probe for detecting amyloid oligomers and preparation and application thereof, and belongs to the technical field of A beta imaging agents, the fluorescent probe is a chalcone derivative, and is particularly developed based on optimization of the process of molecular torsion limited charge transfer and excited state proton transfer of a chalcone skeleton. The probe can be used as a specific fluorescence chemical probe for detecting and imaging the A beta aggregate, can dynamically monitor the A beta aggregate in an in-vitro fiber forming process, and has important significance on A beta related pathology detection and research.

The application discloses a crusher material automatic grading control method and system based on image recognition, which comprises the following steps: collecting a dynamic image sequence, extracting deformation gradient, normal change rate and edge disturbance features; collecting torque signals and the like, constructing a dynamic sequence and extracting a chaotic dynamic feature vector; collecting stress and acoustic vibration signals, and fusing to generate a multi-field collaborative feature vector; inputting an improved ResNeXt network, fusing three types of features, and outputting particle size classification and deviation information; constructing a grading evolution controller, performing strategy adaptive reconstruction, and generating optimal control instructions; and executing discharge port, rotating speed and feeding adjustment, and closing loop feedback to the previous process to realize dynamic control. Through the fusion of dynamic image topological features, crushing dynamics features and multi-physical field features, and in combination with an adaptive evolution control mechanism, high-precision identification and full-automatic optimal adjustment of the particle size of the crusher material are realized.
